This is the obligatory first post.

If you are here , it means you care one or more of the following: Raspberry Pi, Apple, Linux or computer application development.

On this site I'll put Raspberry Pi news , and I'll be gathering interesting things I found about the above themes.

Everybody know me because my Google Docs and you must understand that I do this just for fun, and because I have seen interest from people.

If you want to know something about me, you can.

Tomorrow I'll start with the regular post, and I'll recovering from Google Docs daily news gradually.

As I have not yet implemented a commenting system, you can leave me any questions, encouragement or whatever you can think here:

Why Raspberry Pi?

Raspberry Pi

First because it is impressive that a project that cost created by a few people with some extraordinary skills.

Second because it is so optimized pcb allows you a media center, a download center, a server, your own cloud or recreative game machine in the size of a credit card. Is it not amazing?.

It also allows me to keep in touch with my Linux side, asleep but latent at least. I liked so much that has been the perfect excuse.

Burn Linux OS to USB/SD from OSX (Terminal)


Today we'll see a simple way to burn a Linux operating system image, any flavor or variety, in a flash drive or SD card with OSX. If you are interested ...

The steps are quite simple:

  • Download the iso. We are going to call generically ubunarch.iso (lest you dispute)
  • Once downloaded, open the terminal and type the following command:
    hdiutil convert -format UDRW -o ubunarch.img ubunarch.iso
  • Now let's see where our USB/SD drive are:
    diskutil list
  • Unmount the drive (if not unmounted, re-run the command). N is the drive where you want to install the operating system:
    sudo diskutil unmountDisk /dev/diskN
  • Now we'll copy the image to the device (replacing N by your drive and ubunarch with the name of your file):
    date +'Start: %H:%M:%S' && sudo dd if=ubunarch.img bs=1m
  • Well done!. Now before removing the drive, unmount it with (keep an eye to N):
    diskutil eject /dev/diskN

EXTRA!: Possible new x86 emulator


One of the things that attract me from Raspberry Pi was emulation. Unfortunately,Dosbox port it's very slow in most distributions (It's said that on RISCOS works fine).

I got in touch with Patrick, developer of one of the best Nintendo DS x86 emulators, to see if it would be possible a port from a86, and this is what he said:


I am currently working on an Android port (called ax86) of my DSx86 emulator, but after I get that done I would like to at least look into porting it to Raspberry Pi as well. I believe much of the stuff I do for Android I can also use with Raspberry Pi, and I would not even need to worry about keyboard and mouse emulation, as I can use the real hardware. :-)

So, in short, yes it is possible, and I might start working on it some time in the future."

OpenMSX compiled for the Raspberry Pi!


Do you like the news about emulators? I love them. Always try the emulator and after 2 minutes I'm bored. True story.

I've had several computers in my life, but my favorite is the MSX.

Now I have the opportunity to play Athletic Land on my RasPi.

As argument in the forum the user who has decided to compile, it works well with the 900 Mhz configuration. If you want better, press F10 to open the console and type "set scanline 0"

The BIOS should go into "/home/pi/.openMSX/share/systemroms/", and it is recommended that you have at least msx2.rom and ms2ext.rom

You can add it to EmulationStation. Adding the file es_systems.cfg following:

DSx86 port on the way


A few days ago I mentioned the possibility of a new port for Raspberry Pi. It's purpose is to allow you to run old DOS games on your Nintendo DS game console. Patrick told us that he might start working on it some time in the future.

Well. Its creator was kind enough to get back in touch with me to give me the following news:

"Hi again!

Just to let you know, I just today buy a Raspberry Pi. So, the possibility that I will port DSx86 to it increased considerably today. :-)

Tip: save and compress at the same time with dd and gzip

An interesting tip I've found:

To save and compress, the command is as follows (replace xxx with the ID of your disc):

dd if=/dev/xxx conv=sync,noerror bs=4m | gzip -c > xxx.img.gz

To decompress and restore, the command is as follows (replace xxx with the ID of your disc):

gunzip -c xxx.img.gz | dd of=/dev/xxx conv=sync,noerror bs=4m 

For other operating system than OSX, use capital M.

I found an ATI drivers offered to install it without complications. You can also install the Intel drivers too if you have it, which is essential today.

Main advantages:

  • Always Up-To-Date Drivers.
  • No dependency from your official notebook manufacturer.

rpix86 progress


Like I said in some moment, we'll have soon a new x86 emulator, for those who wish to run any oldies game or application.

The progress is doing is to match the emulator that already has on Android called ax86.

From what I read, It will be support directly from the GPU for graphics modes, which is good for the speed issue (now emulate a 80486 20MHz). One problem is the operating system and their optimizations (we think Raspbian). You also have to think that we only have one CPU, which must be run all the processes of image, sound, input,...

On his blog you can see a screenshot from the game Little Big Adventure.

From here I continue to bet for this emulator, and if you want to donate in any way to the cause, you can do it.

The tip is to keep your profile in RAM. This uses the tmpfs filesystem.

The benefits, would be to reduce disk writes, keeps your SD Card safe, increased speed and responsiveness (They said up to 50%), especially in the use of plugins.

To do this, run these three commands in the terminal or console:

sudo wget
sudo chmod +x install
sudo ./install

ChameleonPi 0.3 & PiMAME 0.6 Beta out!


This weekend we have an important mission. No matter the emulator or the game, but the platform.

Our case, Raspberry Pi is becoming one year after launch, a platform for games, media center and very interesting projects.

ChameleonPi it's a Raspbian remix without the X graphical environment that uses it's own launcher to run emulators for old computers, arcades and consoles.

This version brings new features:

  • Added NES emulator

  • Added SNES emulator

  • Support for Joystick

  • Added pdf reader

  • Bug Fixes

The image is only available this weekend as a direct download.

PiMAME is similar, but mostly just to MAME and more optimized for this system. New of this beta are:

  • Support for the XArcade Tankstick.

  • New menu at start to choose options before launching emulation.

  • PIP (the Pi IP service) is available to install (but off by default).

  • New admin options in the web frontend to Reboot and Shutdown your Pi.

  • Smaller image should now install on most 2GB cards (with some room to spare).

Automation university project with Raspberry Pi (Spanish link)


I found a pretty curious post about home automation project that I want to show you. Nothing better than the words from the author about this project to know it:

I recently presented a project with the Raspberry Pi in college where I study Computer Science.

The goal was pretty generic and was used GPIO pin header that brings the Raspberry Pi and to control the I/O from a mobile device.

So for this project I thought of making a model of a home and simulate home automation.

Raspbian Server Edition Version 2.3 1GB Image

Probably few people need such a small image of the server version from our friend Madman, but it is worth mentioning the decrease of size for an operating system to fit on 1GB. Remember that there is not an iso, It's an img file.


MAME4ALL port for Pi


Sometimes I think the only thing that interests me from Raspi are emulators. I see Frogger in the Pi and the nostalgia come to me :_)

This time we have an old version (v0.37b5), but games are working at full speed. It's RasPi Optimized and uses dispmanx graphics, SDL input and ALSA sound. It works with X-Windows and console.

Still no joystick support, but work on it.

Recommends the following configuration in config.txt file (tested on B model, 512 MB)

10.000 Hits!


Well, I have nothing prepared for this great event, but it deserves a few words.

Two months have passed since the blog started. There are still many things to do around here, and as you know I've been out a few weeks because of my wife.

Almost 100 post, visitors from USA, UK, Argentina, Chile, Germany, France, Mexico and particularly Spain.

First, let me thank the comments of encouragement that I have received, both on Twitter and in the blog. It seems silly, but I was excited about your comments on this difficult moments, and this makes a difference to me. Now you are part of my circle, as would said Google ;)

Now it is making some progress on the web (I hope I do not take another 10,000 visits). Most you come here to read news about Raspberry Pi, I know, and forgive me that sometimes post content that interests me. Let's see if I can separate content for anyone having to read any of the other topics that interest to me, both in the feeds and with the sections in the header.

Of course, any improvements or advice you may offer, are welcome. I also want that this blog to be a point of interest to help you spread your post or blog. Whenever you want to give visibility to your post, please send me your link, which I will publish it. Ditto if you have a store or business.

This post is dedicated to my wife who encouraged me to continue the blog, and my daughter, who can't stop dancing Mickey Mouse Club House and were it not for the 27" iMac, it would be impossible to devote time to blog .

And you, of course!. Hope to continue reading, the best is yet to come...

rpix86 is ready! (updated post)


rpix86 is based on DSx86

It's available the first release of this emulator for x86 systems!.

It is still in beta and has a lot to do. It runs once downloaded typing rpix86 or rpix86 -? for detailed information. To exit, simply press ESC or CTRL-C

For now only runs on console, so exit the desktop environment and start reminiscing abandonware classic.

Thanks Patrick!

2 useful Mac tools: PiCLoner & PiWriter


I have two applications on Mac to create a backup of your SD card (PiCloner) and another that is a graphical interface to copy the operating system from the .img file to SD (PiWriter).

Remember the right way to do the same as PiWriter in the Mac Terminal:

N is the drive of your SD card
$ diskutil list
$ sudo diskutil unmountDisk /dev/diskN
$ date +'Start: %H:%M:%S' && sudo dd if=myImage.img bs=1m of=/dev/rdiskN

PiBang Server Edition


The previous post was my 100th post, and I see that every day is more difficult to find updated news about our Raspi. Many blogs have several days without updating, and perhaps means the Pi fever is down. Hopefully not.

We all tend to use either Raspbian or Arch Linux. Sometimes they do not bother to try other alternatives. Wrong.

PiBang is a good solid distribution now takes a version Server, all command-line based on Debian and access to their repos. Also you may be interested in their desktop version that uses OpenBox instead of LXDE, lighter.

RasPlex: New Media Center Distribution

A blog reader called Hugo Ruiz, told me days ago we have a new distribution based on OpenELEC, but using the Plex app, which as many of you know, is an alternative with enough followers to XBMC.

It's still in beta, but it works pretty well. Supports AirPlay and AirTunes.

Search files & directories on Linux


Today we will learn how to search files and directories filtered with various parameters.

The command we use is find. Consider a few examples:

# find / -name -iname '*hta*' -size +100M -mtime +3


  • The complete system (/)

  • All files or directories containing hta ('hta')

  • Ignoring case (-iname)

  • With size larger than 100MB (-size +100 M)

  • Files modified more than 3 days

# find / -empty

Find files and empty directories (-empty)

As a final command, the following will search the folder sizes ordered from lowest to highest:

# du -hs $(du -s * | sort -g | awk '{print $2}')

RetroPie Project: Definitive Guide!

RetroPie Project splash boot

I'm very excited to share with us this post :D

I decided to make a tutorial a little longer than usual. Today we will test this distribution based on Raspbian and making accessible to anyone the world of emulators with a Raspberry Pi as I mentioned above. Let's Start!

NOTE: This review is based on SD-card image from 03/07/2013, but also is valid for the script you can find on GiHub.

Download the img file (1.3 Gb) and copy it to your SD-card. Either method is valid.

The first thing we get once we started the SD-card, it's a notification if we have connected a joystick or pad. It is appreciated this setup screen, because sometimes is quite complex for many of us to configure the joystick in the Terminal. Anyway we need to execute a command to have joystick support in all different emulators anyway.

What does we get once we booted?

The first thing we see is the next screen.

Cave Story

"Cave Story is a freeware platform-adventure video game released in 2004 for the PC. It was developed over five years by Daisuke "Pixel" Amaya in his free time. Cave Story features 2D platform mechanics and is intended as a homage to the classic games that the author played in his youth, such as Metroid." - Wikipedia

Menu Control and management

we move with the cursor or pressing left or right with the control pad. We will move around emulators which have ROM or game uploaded.

By pressing ALT+F1 show us the following menu

Menu pressing ALT+F1

We can see several options: Restart, Shutdown, Reload and Exit. With the last option we will go to the Terminal and we'll have Raspbian distribution ready to use. I recommend to expand the file system if you have a SD-card over 4 GB running raspi-config and overclock to 900 Mhz.

If you have a joystick, you also need an aditional step as I mentioned above because the script does not correctly configure the control in all emulators. You'll have to run a program to configure the control pad in the Terminal:

cp ~/RetroPie/configs/all/retroarch.cfg ~/RetroPie/configs/all/retroarch.old
cd ~/RetroPie/emulators/RetroArch/tools/ &&
./retroarch-joyconfig -j 0 >> ~/RetroPie/configs/all/retroarch.cfg

With the command above you will have the joystick calibrated to all emulators. The first one make a copy of the configuration file. The second one setup the joystick. Parameter -j 0 is for setup the first plugged joystick. Run again with 1 for the second joystick, and so on...

Initially appear in the menu the game Cave Story, Doom and Genesis emulator (Megadrive), although the latter two doesn't work until you upload some ROMs. Let's load some games!

Remotely accessing the distribution

We have several choices. By default we can access from our internal network, since it has been configured Samba so we can seamlessly access. Another possibility is to activate SSH, but I recommend the first one.

Samba bring us access to games directories

After copying the ROMs, it is best coming back to the ALT+F1 menu and select Reload or Restart.

Well, let's play some emulators, not all. Wait!... It's gonna be so easy!

ZX Spectrum

We start the emulator and the next screen appear

Failed to load a game directly

Damn, it seems the emulator is based on FUSE under X-Windows without joystick support. You have to load games from File menu. I prefer the Terminal based version because it brings joystick support (or I have not been able to successfully configure). Aside must be configured to have more screen resolution. This can be done in the Option>Extra... menu.

FUSE emulator

You must to configure the screen size if you think it's small. Here you are the options

If you need the joystick and better full-screen support, I'll teach you to install another emulator. First you have to exit to the console (remember, ALT+F1):

$ sudo apt-get install fuse-emulator-sdl spectrum-roms

$ nano ~/emulationstation

And we changed the final ZX Spectrum section the following line:

COMMAND=fuse-sdl %ROM%

Options appear by pressing F1. With Options>Full screen put the emulator in full screen, and Joysticks have options to configure how you want your pad. It's a matter of trial and error combinations, since according to the game sometimes you have to select Sinclair1 or Kempston. Remember to save the configuration with Options>Save. To change the game, File>Open.

Super Nintendo

Best SuperNes game. Don't you think?

Super Mario World!. It's running at full screen and it's pretty fast and stable. No comments :D

Sony Playstation 1

Pretty slow to load the iso, but it's ok once is loaded into memory

Do not forget to copy the scph1001.bin bios with the isos in the same directory. If doesn't work try to copy the bios in ~/RetroPie/configs/psx. Supports both .Img as .7z, and I think that is the only emulator besides MAME that supports compressed files.

It also supports .bin files, but you must modify the ~/.emulationstation/es_systems.cfg to support these files. Just add .bin .BIN to EXTENSION= in the appropriate section. Perhaps best is to rename the .bin to .img or compress on .7z format, you decide.

NOTE: Make sure inside the file .7z you don't have the .bin into any directory.

Genesis (Megadrive)

Hellfire running with DGEN. I love the music from the 1st stage

Perfect! It works the control pad and the game run at full screen with no problem.


It appears the front-end emulator, but it's not taking the directory where you uploaded the game from the remote computer, so you have to change it clicking on Add Game y following the path /home/pi/RetroPie/roms/scummvm

Add Game menu from scummVM

It's done! :D

The Secret Of Monkey Island running on scummVM


Final Fight!. Insert coin! Insert coin! Insert coin!

It seems that the speed is pretty good. Remember that if you have joystick and you have not configured under Terminal as I mentioned above, will not work. If you download ROMs from Internet, some of these will not work, because we are running the AdvancedMAME port, despite being the most compatible, you may have problems with any of the .zip files.

Game Gear y Game boy Advanced

Sonic was very adictive on Game Gear. SEEGAAA!

Perfect for Game Gear, nothing to add except that we may have to modify some values to display at full screen. Sound on GBA is lamentable. I forgot to mention that each one has its own retroarch.cfg configuration file in case you want to customize it. You can find it in the folder ~/RetroPie/configs/


Losers guys in the world of FPS

No matter: Doom1, Doom2, Everything works perfectly with full screen and joystick support.The .wad file already installed doesn't work, you must search it on the internet or in your floppy disc. The engine has support to doom.wad, doom2.wad, heretic.wad y Hexen among others.


A prize to someone who know what's that game

Not yet supported as many others you can find in the image file, but is available the Amiga emulator called Uae4all. Here are the steps to follow and enjoy any game of this system:



Starting emulator:

Alt+F1 to exit emulationstation

cd /home/pi/RetroPie/emulators/uae4all/

This starts the emulator. NB kick.rom has to be called: "kick.rom", this is case sensitive. If it is called Kick.rom you will get an "error:disk not found".

A box will appear. Choose: "select image disk" and find the game to load in the appearing browser window. To start the game choose Run.

NOTE: Thanks to user called FreddyT for share the comment with us.


The best of this project is that the joystick or pad support is a good idea. It could be bring some freeware ROMs, but everything is working out of the box.

The project have many features to publish several articles. The options we have in the retroarch.cfg configuration file opens a range of possibilities thanks to libretro library in which the system is based. I found a Wolfenstein 3D directory and others.

I miss the Scrapers as PiMAME prepared by Shea Silverman already commented recently. I think is understandable and can be configured, because all of these distros are using the EmulationStation if I no mistaken.

Also remember that if you have a controller connected by the GPIO connector, you can make use of it and play with your native Nintendo, PSX, PSX2, SuperNes, N64 or GameCube controller.

Thus far we have come. I hope you enjoyed it. I'd like to ask you... Do you want a second part of the post? ;)

Ubuntu 13.04 on a 27" touch screen

It's amazing how well they have mastered the touch system in the Ubuntu updated operating system that has to go out this month.

I believe that although I have always seen it as a waste of time, since the keyboard and mouse will always be much faster than touching the screen and staining it, are moving in a very positive way with this control system.

If they want to somehow revive repetitive features that are occurring in the operating systems and to copy each other, one will have to uncheck from the rest.

Ubuntu although criticized for decisions that are altering its operating system for better or worse are trying it at least, and I dare say better than Microsoft with their Windows 8.

I honestly do not believe me just yet (especially being the April fool's day). As discussed is quite stable, and completely moving environment with OpenGL, so the speed must be amazing.

I think Raspbian now has a serious competitor if all the talk about this is true.

rpix86 v0.04 released!


We have a new version of our favorite MS-DOS emulator.

I would like to say one thing to Patrick after the criticism he has had because some routines he have copied from Dosbox ...

This blog was the first who contact with Patrick and get the news that was developing rpix86. We always had excited the idea of a MS-DOS emulator as worthy as it has in other platforms, and each new version we have always proclaimed the good work of this guy.

Maybe we have not generated as many visits as others blogs because this modest blog is quite specific and sack the news that others will not take or do later. But I'm going to continue posting news and contributing with ideas so we can all remember those old glories days.

The most important information about the changes in this new version:

  • Added support for 80x50 text mode. This is used by some of my old MIDI software, and also by Little Big Adventure setup program.

  • Added support for USB analog joysticks (and foot pedals). Like in the old DOS days, up to 4 buttons and 4 analog channels are supported.

  • Added emulation of Roland MPU-401 MIDI ports in "dumb UART" mode. All the MIDI commands are sent to /dev/midi1 device, so if you have a General MIDI synth connected to your RPi using an USB MIDI dongle, you should now get proper MIDI music out of your DOS games.

  • Stripped out the debug symbol information from the executable, as that decreased the size of rpix86 to less than half of what it was.

Thanks a lot from a rpix86 mega-fan!

Optimize and speed up your Raspberry Pi


Ever since my first PC 286 to the present days, I have been obsessed with optimization: an operating system, programming code, an application...

We are going to know how to optimize a little our Raspberry Pi.

At the time of MS-DOS I had the cleaner autoexec.bat and config.sys in my neighborhood, and also created a Windows XP distribution of those Lite called Protini that was quite famous in some forums.

That which does not require running, Why have it in memory? I'd rather have RAM or free space used by processes or programs that do not use.

So I will be putting commands and support for those who need to accelerate Raspberry Pi to infinity and beyond. If you want to bring some other command or trick, you can send it to me and we will build this post among us: D

Let's start with some simple processes for those who just walked into the desktop environment among others. The following commands can be copied to a file for later run or enter them manually one by one.

## Stop the ntp service
sudo service ntp stop

## Stop the triggerhappy service
sudo service triggerhappy stop

## Stop the dbus service. Warning: this can cause unpredictable behaviour
 when running a desktop environment on the RPi
sudo service dbus stop

## Stop the console-kit-daemon service. Warning: this can 

unpredictable behaviour when running a desktop environment on the RPi
sudo killall console-kit-daemon

## Stop the polkitd service. Warning: this can cause unpredictable 
behaviour when running a desktop environment on the RPi
sudo killall polkitd

## Remount /dev/shm to prevent memory allocation errors
sudo mount -o remount,size=128M /dev/shm

## Kill the usespace gnome virtual filesystem daemon. Warning: this can
 cause unpredictable behaviour when running a desktop environment on the RPi
killall gvfsd

## Kill the userspace D-Bus daemon. Warning: this can cause unpredictable
 behaviour when running a desktop environment on the RPi
killall dbus-daemon

## Kill the userspace dbus-launch daemon. Warning: this can cause 
unpredictable behaviour when running a desktop environment on the RPi
killall dbus-launch

## Uncomment if you'd like to disable the network adapter completely
#echo -n "1-1.1:1.0" | sudo tee /sys/bus/usb/drivers/smsc95xx/unbind

## Set the CPU scaling governor to performance
echo -n performance | sudo tee /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

To be continue...

PiMAME 0.4 Beta 4

New version of this distribution which now supports more emulators. From here we give Shea Silverman Congratulations on your marriage, because he has been married a few weeks ago.

Curious that this distribution called PiMAME and we all know, now support more emulators and somewhat neglected which gives it its name, as there is a speed problem in AdvancedMAME.

This release includes:

  • Neo Geo support with the GNGeo emulator!!! (Full Speed and Audio)
  • Neo Geo roms and bios are stored in the same Roms folder.
  • Raspbian upgraded and updated.

Arduino Uno vs BeagleBone vs Raspberry Pi


I have a few days between work extreme fighting with MySQL and leisure spending PAL to NTSC audio from Mac to put in a video. Let's see if I can tinker with Raspi, as I have prepared several tutorials that I hope you like them.

I leave you with an article of those where we like to compare these three monsters of the digital age, they are the jewel of microcontrollers.

Raspberry Pi and GPIO (1)


Probably site Diverteka is one that has more hispanic fans. Its clean Wordpress theme and content so enriching is what motivates us every day to visit their website.

The tutorial presented to us today is known as the great port of our Raspi *GPIO. *GPIO is like that neighbor that we all know but of which we know nothing.

It teaches how the Raspberry Pi communicates with the world, the hardware associated with that port, as well as the way Linux handles the same, finally managing a card (XUE-001) that allows control from a signal Raspberry output and one input.

An article to save favorites and keep it in mind.

News this week...


Well, at last Friday. This weekend we play with our Raspberry Pi. I give some ideas to cover news this week have been several blogs.

  • PiParted v0.03

    Distribution from GParted LiveCD ISO dedicated as you all know to download and install distros from (easy method). Size: 149 MB.

  • Rpix86 has logo!

    Finally have this great DOS emulator logo. Patrick has been busy, but the MIDI synthesizer support continues to progress.

  • PiMAME 0.6 Beta 5 - Now with PlayStation support!

    As you can seen in the video, everything seems to go quite well with the PSX1 emulator. In the next version will come with a distribution updater not have to be downloaded every time an image.

  • New OpenELEC 3.0.1

    Frodo 12.1 Updated with corrections for our Raspi among others, several drivers and packages updated in the distro. Full list of changes here. Download here

  • Starting with Arch Linux

    One of these days I will try this fantastic distro. Fran Carver has an article explaining the first contact he had with Arch Linux in Raspi.

rpix86 v0.06 released!


rpix86 version 0.06 released!

This version contains the following fixes and improvements:

  • Added serial port emulation support (use the new -sNUM parameter).

  • Changed the -h and -w parameters to not force 4:3 aspect ratio.

  • Added 4DOS.COM download question dialog when starting in X Window.

  • Added an icon to rpix86 when running under X Window environment.

  • X Window title bar shows now also the version number of rpix86.

  • Keyboard and mouse reading is slightly more efficient than before.

Remote monitoring with an RC car, Arduino and the raspberry pi (translated link)

Monday and I could not have touched the Raspi, but I have something going on... ;)

I link to a post that I found quite full. I dedicate it to my father, who sure likes.

Translated link:

Beaglebone Black comes to stay with us


It seems that the Raspberry Pi had its moment of glory, and is already looking for another PCB to do more for the same price. Beaglebone has fit some features of your card, and now sell for $45. Is it worth it? Let's see its features...

Took several days looking for interesting information to post on Raspberry Pi and it seems that everything has been exploited already in our Raspi. We do everything with it: emulators, robots, speech synthesizers, home automation, download media center, servers. The possibilities are endless and its usefulness goes beyond a simple desktop computer.

Those who have always opted for a reduced price equipment and the possibilities we have raised, we see in the Beaglebone competent rival.

Hardware Specs

This new version calls himself Beaglebone Black. It come with a ARM Cortex-A8 1GHz processor (ARMv7 v6 compared to the Raspberry Pi), 512MB DDR3, Graphics Accelerator, microHDMI, miniSD, 2GB of internal storage for the operating system Angstrom Linux among other features.

Those who missed it have a good operating system, we can install Ubuntu (Did not you say good OS?) Or whatever ARMv7 compatible, Android included.

For those who like to be in contact with the outside world, has connections to get bored.

They are $10 more than RasPi, but as they say, comes with the power supply and network cable, not to mention the internal memory of 2 GB with Angstrom Linux preinstalled.

Is it worth buying then one Raspi? Depends on what you're going to use it. Today we have taken advantage of this pileup to levels that would not have never imagined at first. He still has plenty of life, and will continue in the gap much longer. There is no planned obsolescence, but if you want a half decent desktop environment with a good web browser (yeah, with Flash support) or to run Android, Beaglebone is your alternative.

Raspberry Pi: Making Raspbian OS Lite (under 500MB)


Today is one of those days that excites me. First, today Canonical released a new Ubuntu OS and with a new version I feel like a child to test it on my iMac. So today did not bother me, LOL.

Second because the tutorial that I found today is on diet Raspbian distribution for those who do not get into LXDE for anything, and we connected our Raspi Ethernet cable. These are simple steps, and you lose nothing to try the script that have element14 forum.

Read/write on ext2/ext3/ext4 partitions from Mac & HFS+ from Linux

Ubuntu 13.04 on iMac (mid 2011)

I have spent almost a week with Ubuntu 13.04 on my iMac, and the most difficult to me was to config the keyboard and mouse Bluetooth and access to both partitions from each operating system, more mostly by ignorance, so here are my notes, because has not been easy to find the solution. Let's Started!

Access HFS+ partition from Ubuntu

In theory, we can access the file system without problems, but when we try it on any folder in /Users/yourusername, we find the following message:

Access denied to the folder

To fix this, nothing easier than starting our OSX, and right click on the folder you want to access from Linux and select Get Info. Below, we can see the user permissions. In our case, we will share the Downloads folder.

We see that the permissions for everyone is set to No Access.


So we change it to Read or Read/Write.



TIP: Maybe is not a good idea to OSX that you set up write permissions in your file system from another operating system. As a general rule I set read only, and create a NTFS partition to data exchange.

With these steps, you will have access to the partition of our OSX and best, without installing anything.

Smiley happy

Access ext2/ext3/ext4 partitions from OSX

To access our Linux partitions, we will install two applications: OSXFUSE and fuse-ext2.

Install FUSE

Once you reboot the system, we will have access to our Linux file system, in this case disk0s3.

FUSE partition

I recommend its use in moderation, and with a little care when copying files. Better if you use it to read files. Until next time!

PiMAME script installer

First of all thank you for the 30,000 unique visitors that we've been living experiences together with our Raspberry Pi. Hurrah!.

Our friend Shea Silverman has been kind enough to arrange for us their PiMAME installation script from their Raspbian distribution, which we will be able to enjoy your compilations in any OS we want. Let's see how to install it.

The script will install all you need to run PiMAME, including Frontend Web, FTP server, etc...

Let's install it. We walked into our favorite distribution and type:

sudo apt-get install git
git clone
cd pimame_installer
sudo. /

To update once we have installed:

sudo. /

To uninstall PiMAME, nothing easier than typing the following:

Preconfigured Airplay speaker (Shairport) - Raspberry Pi image


Sometimes compiling an application by ourselves can even cause more of a headache. Perhaps it is the case that we do not have much time, and we seek the simplest solution.

In this case, a user has created a Raspbian version of this music server using AirPlay V 1.0 protocol running like an AirPort Express station. You can have your entire music collection on a desktop computer, iGatgets or Android and play from Raspberry Pi.

It has been tested with Airfoil (PC/Mac) and Honey Player (Android).

Raspberry Pi motion detector with remote alert using Realtime and Python


Motion technology takes years between us. It allows us to perform certain actions upon detecting a change in an image or video.

The tutorial I found seems interesting, and who knows, maybe I make a tutorial about it. Here we discuss Sergio Costa uses Motion as capture engine, and Realtime for system messages on the server.


News these days in the Pi World


Weekend AFK. Let's do a review of what happened these days...

  • MAGPI Num. 12: This monthly electronic magazine available in paper format too, this time talks about various distros for our machine, printing with CUPS2 and making music with SCHISM.

  • Update XBMC 12.2: The interesting thing for our Pi is in an error with video codecs and audio. Changes are already included in your favorite distros (OpenELEC, Xbian and Raspbmc), you only have to update them.

  • FirefoxOS for Raspberry Pi: Looks like we have an image to test this new OS. Not as mature as a few months ago, but we can not make use of keyboard and mouse apparently. The thing promised.

  • Formatting an SD with a Mac: It is trivial for some of us, but others do not know how.

  • Beaglebone Black vs Raspberry: It appears that the BeagleBone not yet a Raspi Killer, do you?. Decide you with in this article.

  • Building a scale machine with a Raspberry Space Invaders: These are the projects that make you think of someday you could do by yourself, but you do not find the the time.

Voice Control on the Raspberry Pi 2.0

This script use Google's APi to speech recognition

Sure we've seen on more than one occasion our Raspi executing actions via voice commands. A user called Steven Hickson shares her script with us to do the same with your Raspberry Pi as simple as be possible.

On his blog you can also find very interesting scripts, do not miss out.

New shared notes: Ubuntu join to the family


Family grows

I like Ubuntu, I feel comfortable with him on almost all flavors least KDE (Flame wars!). Now you have at your disposal my most beloved script for this flavor updated on the lateral bar.

In Spanish, but perfectly understandable.

They are notes I try one day be a script really. Being able to run quietly and without fear when you have Ubuntu just installed, go for a coffee, and when you come back you'll have your operating system with steroids. You are being warning. I hope you edit with your preferences.

Before we had shared for a group of people and now I make it available for my followers. So here you have it.

Now you can pass from having a heavy slow Ubuntu when you boot the system, who I'm pretty sure will occupy more than 600 MB in memory, to this:

Raspbian updated!

Just read the news that upgrading the distribution

sudo apt-get update && sudo apt-get upgrade

we have a new batch of updated packages, most notably support for new camera from the creators of the Raspberry Pi and available soon and new option in the raspi-config script.

Kernel 3.8.12 +

There's also a kernel updated. The easiest way we have is running the Hexxeh's script. Instructions for installing and upgrading the kernel as follows:

sudo apt-get install git-core
sudo wget -O /usr/bin/rpi-update && sudo chmod +x /usr/bin/rpi-update
sudo rpi-update

Install Subsonic server in Raspbian


These days hard to find a story that has something of interest to the community.

Well, all you have seen the camera from raspberrypi's guys sold out in half a day. It happens like the Apple's products: first you buy and then think what you'll use. Too much hype I think.

Returning to the subject of the post, the most interesting thing I found in one of my favorite sites is this tutorial to use the Subsonic application, which is the same as having Spotify but with your music, and accessible from anywhere in the world.

And it's free, as we like.

The idea is to mount a Java-based server, download a .deb and now from any web browser on the network, access to http://ip_raspberry:4040/

As I've been reading over, have to support video streaming. You may have to check it out in depth. It has applications for all platforms.

Install RetroPie on BerryBoot 2.0 (spanish pdf)


We love RetroPie, and recently commented that I have several SD cards. Many times we miss, because you never will go to fill a 16 or 32 GB SD Card, so Berryboot comes to the rescue to install more than one distribution to a SD Card.

A user has been kind enough to share with us a pretty elaborate tutorial to copy RetroPie and any other operating system on a SD Card with Berryboot.

Thanks Mirror from all of us.

We compile L'Abbaye des Morts for Raspberry Pi (.deb included)

L'Abbaye des Morts

Cover from the indie game L'Abbaye des Morts

POST UPDATED: 18/06/2020

This week is challenging.

I've tried to compile a program for the first time in the Raspi and see the steps to do it. For this mission I wanted to port a game and make tribute to its creator Locomalito, which has become a little more famous than he's already because the great game Maldita Castilla for Windows.

I include the .deb package if you don't wanna compiled by yourself at the end of the post.

Here we go!

Start from the beginning

Locomalito is a user who develop video games just for fun or to get some goal: program, draw, and with his friend Gryzor87, which composes the soundtracks for their games, are able to create a nostalgic magic that surrounds us and traps in time, all with an retro-indie style.

L'Abbaye des Morts trailer

In the 13th century, the Cathars, who preach about good Christian beliefs, were being expelled by the Catholic Church out of the Languedoc region in France. One of them, called Jean Raymond, found an old church in which to hide, not knowing that beneath its ruins lay buried an ancient evil.


The first thing we found when compiling a program is knowing what libraries have been used. Generally we have a README file who indicate the libraries who has being used. Let's go to download the source code.

We visit their website where we can find information about the game and several extras like posters, manuals, soundtrack among others. Click on it. In the download's area we see the source code file called abbaye-for-linux-src-1.11.tar.gz at the time of the article.

Well, we have downloaded in our Raspi. Now uncompress it:

tar -xzvf abbaye-for-linux-src-1.11.tar.gz

We go into the directory and take a look to the readme.txt or README in this case.

The program requires the GCC compiler and SDL libraries.

In this case, we found the necessary packages. Just install with:

sudo apt-get install gcc libsdl1.2-dev libsdl-mixer1.2-dev libsdl-image1.2-dev libsdl-ttf2.0-dev libsdl-gfx1.2-dev

Now from the uncompress directory, execute the following:

make abbaye

The program will read the configuration file and will start the makefile's compilation.

It was made it easy. What if we unknown what dependencies need to install? The best friend you have to search dependencies is apt-file, which indicate to us, passing as parameter the name of a file, their package. Just install it with:

sudo apt-get install apt-file
sudo apt-file update

their use is simple: sudo apt-file search package_name

Installing the binaries

Ecstasy comes when you see the program compiled without errors.

Install it by running sudo make install. Now you can play it from the console by typing abbaye or from X searching in the game's menu section.

Main menu

In case you want to uninstall, sudo make uninstall

Patching the code

The game may consume many CPU cycles, is playable in the X, but there is a small flaw when running on the console due to screen flicker which makes it visually unplayable. This defect will serve to teach you what means modify the source code.

If we go to the place where we extract the source code, we note that is structured into several files grouped in directories. We are interested in the /src/main.c file.

As we know that the bug corresponds to the graphic section, we seek something about SDL initialization. A few lines from starting the program, see the following code:

#ifdef _RENDER_320_240
  pantalla = SDL_SetVideoMode(320,240,8,SDL_HWSURFACE|SDL_DOUBLEBUF);
  pantalla = SDL_SetVideoMode(640,480,8,SDL_HWSURFACE|SDL_DOUBLEBUF);

If we go to the SDL documentation, we see that there are several graphics modes and that one of them will fix our mistake.

Searching in Google find that the failure is due to double buffering, so we changed those lines of code to work only with the CPU:

#ifdef _RENDER_320_240
  pantalla = SDL_SetVideoMode(320,240,8,SDL_SWSURFACE);
  pantalla = SDL_SetVideoMode(640,480,8,SDL_SWSURFACE);

Notice that there are several possibilities to fix the flicker, but the case was to show you how to modify the source code.

Done. So we just have to repeat the above steps to compile and install binaries files with make.

Nothing more. The truth is that it was not difficult at all. We've hit a big game without dependency problems, the challenge to modify the code and I leave for another post the creation of .deb packages. Enjoy it!

What?, missing something?. Aaaw, yes. Take the .deb package. Install it with dpkg-i abbaye-des-morts2-0armhf.deb

RPi-Monitor: Raspberry Pi self monitoring ver. 1.3


RPi-Monitor - Web Interface

Because the alternatives already exist to monitor disliked Raspi, Xavier Berger decided to create his own solution.

RPI-Monitor separates the extraction of information from the presentation layer for security reasons, which is appreciated.

The worst thing is that it does not contain any login system so if you have your server exposed to internet, be careful.

1.3 has these features:

  • Bugs fix related to dependencies of package v1.2.

  • Added package status improvement.

  • Improve embedded server to work with a secure reverse proxy.

  • Add governor info in CPU status

In this new version 1.2 we have the following improvements:

*Bugs fix related to uptime.

*Adding preload spinner for statistics.

*Added package status into status page.

*Prepare embedded server to work with a secure reverse proxy.

*Remove SSL embedded capability (which is not working in RPi) to reduce dependencies.


Download it from the official repository in Github:

sudo wget -O rpimonitor1.2-1all.deb

Install the dependencies by executing the following command:

sudo apt-get install librrds-perl libhttp-daemon-perl

Installation or upgrade can be done with the command:

sudo dpkg -i rpimonitor1.2-1all.deb


The first thing we do is restart the monitoring process with:sudo service rpimonitor restart

To access it, so just enter your browser to the following address: http://IP:8888/ where IP is the IP of your Raspberry Pi.

Fastdosbox speed up dosbox over 250%


Like their creator said: Fastdosbox is a fork of dosbox, based on the sources of dosbox SVN. It brings to Raspbian the dynrec x86 emulation. In other words a boost of 250% over the official version.


*Speed of a 386DX @ 25Mhz thanks to dynrec x86 emulation.

*Splendid upscaling using dispmanx.

*Based on the sources Dosbox SVN and Dosbox 0.74.

*Between 200% to 250% the speed of Raspbian dosbox v 0.74.

*Console only, no support for X11.

To make it work once installed, go into the game directory and write dosbox exec where exec is the name of the executable, which is usually a .EXE, .COM or .BAT

The have available for 2.49 euros in the PiStore, which I recommend, or you can download the compiled free version compiled by myself (steps to compile apps was mentioned in another post) from this link.



Pidora 18 release


Sorry, but I needed to do this xD

Pidora is a distribution based on Raspbian who has changed backgrounds, icons and sounds and now it seems Dora the Explorer (hence its name).

Just kidding :P

Pidora is a Linux software distribution for the Raspberry Pi computer. It contains software packages from the Fedora Project (specifically, the Fedora ARM secondary architecture project)...

Its compiled specifically for the ARMv6 architecture used on the Raspberry Pi packages which have been specifically written for or modified for the Raspberry Pi, and software provided by the Raspberry Pi Foundation for device access.

There are some interesting new features we'd like to highlight:

  • Almost all of the Fedora 18 package set available via yum (thousands of packages were built from the official Fedora repository and made available online).

  • Compiled specifically to take advantage of the hardware already built into the Raspberry Pi.

  • Graphical firstboot configuration (with additional modules specifically made for the Raspberry Pi).

  • Compact initial image size (for fast downloads) and auto-resize (for maximum storage afterwards).

  • Auto swap creation available to allow for larger memory usage.

  • C, Python, & Perl programming languages available & included in the SD card image.

  • Initial release of headless mode can be used with setups lacking a monitor or display.

  • IP address information can be read over the speakers and flashed with the LED light.

  • For graphical operation, Gedit text editor can be used with plugins (python console, file manager, syntax highlighting) to serve as a mini-graphical IDE.

  • For console operation, easy-to-use text editors are included (nled, nano, vi) plus Midnight Commander for file management.

  • Includes libraries capable of supporting external hardware such as motors and robotics (via GPIO, I2C, SPI).

Wayland to speed up the desktop

First, thank to all of you... 40,000 visitors!. The blog is unstoppable. I received daily several emails thanking to me for the blog and I try to answer the questions from you. The Google Docs has increasingly followers and next week we have our first contest!, So pay attention.

As you know, the desktop can be a bit slower to move around than you're used to on your Pi. This is because all the processing is made by the the CPU...

The desktop system is not optimized to use the graphic core BCM2835 on the Raspberry Pi. The Raspberry Pi Foundation and a company called Collabora will remedy this.

If you've seen the video that heads this article, you will see the preview they are riding based on Wayland, a new system that will handle composition specifications coexisting with the X for a new generation that will build the full potential of graphics chips and not just the Raspi. We will look at other platforms and distributions (except in Ubuntu, who have decided to create their own solution).

Wayland core running on the video as we mentioned, but in parallel to OpenGL ES, so we can continue using both 3D renderings, freeing the ARM CPU to handle other tasks.

This will be implemented before the end of year, and we will be able to "play" with it in the next version of Raspbian before launch the final release.


Warranty Services: Farnell


When our Pi or any device under warranty stops working, we always go into a cold sweat and we feel a choking sensation. Then we need to use the warranty service.

I met a user who contacted with me to see if I could solve the problem with their Raspberry Pi. At the end he had to use the warranty with the company Farnell (Spain).

In my case I had to use the Apple's warranty service with a new iPad when it Home button stopped working and they changed it with a new one.

Felipe Maza tells us their story, maybe it can help more than one:

  • In the summer of last year I received a Raspberry Pi bought in Farnell.

  • After 10 months, the last May, 6 my Raspberry Pi stop working, after several tests changing cables, cards and so forth, could determine that the PCB was not working correctly.

  • On May, 8 I write to the technical service Farnell in Spain (link) explaining all the tests I've done.

  • The same day Farnell UK responds with apologizing that the device fails and give me a code to attach to the package with UPS shipping to pick in the direction they say.

  • On May, 9 I give my address.

  • The May, 10 UPS comes to take my Rasberry Pi.

  • On May, 17 they issue a refund invoice for the amount of Raspberry Pi and shipping charges.

  • On May, 21 appear in my account the money, the transaction dated May , 16.

Excellent service with Farnell. We often forget, especially when we buy products to China, what will happen if you device does not work.

Have you had warranty issues with this or another company? Now it's up to you comment.

Thanks to Felipe for sharing their experience.

PiSNES: Super Nintendo Emulator


Port based on SNES9X 1.39.

This is an old version of SNES9X but was chosen as it runs, mostly, at full speed on the Raspberry Pi unlike the more recent versions of SNES9X. Game support is therefore not as good as the newer SNES9X versions and graphics & sound is not as accurate but it plays most popular games very well.

Checkout the readme.txt for more detailed instructions.

The keyboard and joystick can be configured by editing the file pisnes/Full/snes9x.cfg

Games that will not work, for example, are Yoshi's Island, Street Fighter Alpha 2, Star Fox, Super Mario RPG.

PiBang updated!


I always thought that this distro is the eternal forgotten, and it will not be because it's slow.

Today it has just release a new version based on the Openbox variant with SystemD incorporated.

If you want to know more...

In case you do not remember, PiBang Linux is a Linux distribution for Raspberry Pi inspired on CrunchBang Linux, and based on Raspbian although with some differences.

PiBang Linux is moving to SystemD. Please feel free to test it!. Improvements:

  • SystemD, because has a faster boot, it is easy to learn, and it still supports initscripts

  • Terminator will be replaced with LXTerminal

  • XCompmgr will be replaced with Compton (gives us better transparancey)

  • First spin of the updated raspi-config utility.

Do not hesitate to try it and tell us your experience.

Control home automation with android (translated link)

Our friend Juan is right, anyone can assemble a home automation system with a little skill, but if not for this type of articles, we couldn't.

In this case, we are taught to create an interface for our automation projects with AppInventor, which will allow us to design applications for mobile devices in an easy way.

Translated link: RSPPI - Control home automation with android

Warranty Service:


Following this series of articles, we asked the guys at about it's warranty service. We bill directly with Juan de Dios, one of its creators.

When someone has contacted us have tried to fix the issue, in some cases the problem was the client and another the hardware was the problem.

What most have valued us, is that we know about the product, know what your settings and usually produce the same judgments, so the RMA that are generated usually come derived from hardware issues with the SD Card. Farnell knows something about that.*

Another common case is usually video problems, HDMI output does not work after using the RCA, or somehow have to force configuration for some TV, for that also we support.

*The new website is being prepared, and when it's ready a user may initiate a ticket and thus may better manage RMA.

The level of impact on the Raspberry can be around 1%, this little PCB number 90% is a problem in the support of SD card on one side is broken and not making good contact.

At the time that a client is contacted and referred us to a problem, we usually ask for a telephone number to contact, we talk to him, says your case and advise you on how to return it.

At the time we received the item, we check this and we send a new one from our permanent stock.

As always, we have tried to take stock of all items, some of which we are the dealer who has to bear the warranty, if the items like the wireless keyboard, which we bought directly from a supplier in China, if any incident occurs, we are who assume the cost of it, changing it for a new one and if the customer returning dismiss the purchase amount.

Another advantage of this distributor, the fastest to send you a Pi (only in Spain) to your home. Trust the amount of customers that you can read in the timeline of Twitter

Berryboot for dummies (NOOBS)

Geek Gurl show you a new method to install a OS on your SD Card

At least that's what it seemed to me.

NOOBS (New Out Of The Boot Software), is a new way to copy the operating system on an SD. We copy the software image on the SD-card, and once started you must to select the operating system you want to install. You also have option to configure the config.txt. But you get more...

If you get bored and want to install another (removing the previous one, is what differentiates you from Berryboot), press SHIFT during boot process and we have the option to install another operating system again.

The method is created to make it easier to install the various SO, especially for kids.

Raspbian Server Edition 2.4


Don't know how he does, but SirLagz stripped Raspbian in a way that few do, in the best sense of the word.

Probably his Server Edition is the most famous to make our Pi connect to the world to serve websites, ftp or whatever comes to mind.

This time has minified the image size from 1 GB occupying the version 2.3 to a little over 650 MB. It would be nice if someone donate some money to the cause.

Project with Bluetooth dongle: "Who's home?"


I always dreamed when I was teenage, enter my own home and that a woman's sultry voice would welcome me and if I have any mail. The reality is much better because it is my daughter who comes running when she hears the door and gives me a hug (the best of the day). For the first one, there is a solution which I detail below.

The project that I found on is used to enter the house and our Raspi run any command using the communication between a bluetooth dongle and a mobile phone.

In this case, It tell you when we enter or leave home, but the possibilities of modifying the script is there. Does anyone dare?.

Some Configs to Increase DosBox Performance on Raspberry Pi


Over the weekend I like to enjoy some emulators and test/compile some programs (still trying to get some decent karaoke player for the Pi).

I always try to get the best performance for an application, and in this case has appeared in my * Twitter timeline* an article to optimize dosbox or fastdosbox and play Dune 2 natively. Enjoy it.


Voicecommand v3.0 Changes

Here is a small list. I've had some help from a couple of committed users who have come up with some new good ideas which is awesome...

  • There is now a ~ option that finds the word anywhere in a command. For instance ~music==pianobar will work if you say: let's hear some music, play music, or music.

  • !filler is now a string so you can set it manually. If you put it to 0, it will be empty and if you put it to 1, it will be FILLER FILL for compatibility issues.

  • Example scripts have been added in the Misc folder for you to play with. These can send and receive emails and text messages as well as posting to facebook; all using only your voice.

  • Flags can now overwrite the config options and can be reversed by following them with a 0 or enforced if followed with a 1. Ex. if !continuous==1 in your config file, you can force it to run only once with voicecommand -c0

  • The commands and keywords are now case insensitive. So no tricky case matching.

  • Multiple language support has been added. This is based on your country code which I think you can find here (plus enuk and enus). Look up your country code and use that. Ex. For US: !language==en_us, for Spain !language==es, for Germany !language==de.

  • You can set a Wolfram Alpha API and maxResponse (the number of branches) like !api==XXXXXX-XXXXXXXXXX and !maxResponse==3. This will give you better answers. You can sign up for a Wolfram Alpha API on their website for free.

  • Logging has been enabled into /dev/shm/voice.log. It throws stuff to this instead of /dev/null

  • The need for tts-nofill has been removed!! Now tts doesn't use any filler unless you send it yourself.

Hardware Hacking. Lessons for Raspberry Pi (translated)


We often find quality content on our Raspberry Pi, but from time to time any site stands above the rest. Hardware Hacking is starting slowly, but its content is so rich and interesting that I'm dedicating today's post.

These are the lessons we have now:

  • Lesson 0 - Getting the Raspi

  • Lesson 1 - Preparing the SD card with the operating system (Windosws and Mac)

  • Lesson 2 - First Time Setup

  • Lesson 3 - Configuring the GPIO port

  • Lesson 4 - Blink LED (LED flashing)

You are not going to be disappointed, even if we think we know almost all of our Pi, you may be surprised with some other information.

In addition, you can find other very interesting articles about Arduino and electronics among others.

Good luck to the guys at Hardware Hacking and... keep at it!

AEROS for Raspberry Pi


While one native port of AROS (Amiga Real Operating System) continues, here is another project called AEROS pretty interesting.

Want to know more?

AEROS is a hybrid distribution between AROS and Linux(Debian 7.0 for ARM). The pity is that this version to our Pi is only for registered users, but you can access a public beta.

Benefits for AROS users of having Linux under the hood:

  • more drivers (printers, scanners, NIC, Videocards and more)

  • you are able to run every Linux app including Wine (which enables the use of Windows (TM) apps without the need of Windows(TM))

  • AROS - Developers can use Linux development tools

  • AROS apps can utilize Linux tools to enhance there own functionalitiy.

  • Single AROS processes can be forced to run on a single core.

Comparing AEROS beta 1 with 2 on a Raspberry Pi with 256MB RAM

Benefits for Linux users of having AROS on top Linux:

  • Fast desktop, maybe the fastest on LInux

  • Allows you to run AROS apps and games too, most of them come from Amiga and have a low footprint. You will like how fast they are.

  • Allows you to use JanusUAE - an integrated Amiga emulation... classic 68k Amiga apps can be used in coherency mode

As I mentioned, we have a public beta, limited to the option not to install Linux applications. I leave you with it.

12MB Minimal Image for Raspberry Pi using the Yocto Project

The Yocto Project

Image created by the prestigious blog cnx-software using Yocto Project tool and explanation of how to create your own distro. What will you get? An image with just 43 MB occupied space and 20 MB RAM used.

Something that I've always liked it every time a new version of Ubuntu, customize it to create an iso image with my favorite packages: proprietary drivers, upgraded, essential applications to me... Also did the same with XP and XPlite (Do you remember this application?, What times!).

This is a pending task I had in mind these days after seeing the extraordinary work being done by @Manel Alonso to Cubieboard with his own distro called Cubieez. Congratulations!.

The Yocto Project is a platform that will allow us to build an embedded Linux distribution that exactly matches the needs of our projects.

Now I can think about a distribution with no Scratch or graphical environment, or software you will not ever use, lightweight, XBMC and emulators loaded ready to use, with NFS and Midnight Commander of course :P

Do we turn dreams into reality?

Raspberry Pi Reading Car Diagnostics (OBD-II) Data

I never cease to admire the utilities that people find to this board. I sincerely encouraged to find links for you every day like this that I present below.

I have been surprised this morning when I saw as buying an adapter for less than $25, you can diagnose your vehicle and receive information directly in your Raspi.

ODB is a communication standard for reading data from your vehicle if it is relatively new.

Our friend Martin O'Hanlon has developed a GUI to read data through this adapter in Python called pyodb.

I hope someone is encouraged to try.

We have search box on the blog!


We exceeded the 60,000 views!

This is my gift for your confidence :)

If you see the top right of the blog, you can find a search box in which you can input any word or phrase related with the blog. Examples: gpio, pimame, retropie,...

As always, my sin is the perfectionism in the code and in my eagerness to learn more, I wanted something that did not overload the blog and make experiments with other things that I comment below.

[The Beginning]

The first thing I thought was to use a search widget from Google. But it does not get along with sites in several languages, and the outcome is never as customizable as one would like, so I took the long way: Develop it from scratch.


I'm not very good at designing, so I found online the search box in It's made with CSS3 and if your browser is not compatible, it show a clear search box instead of having rounded borders.


I Likes jQuery and I use it day to day. But I want to avoid using it, as after all one of my goals is to learn. Overloading the blog with a library that internally has not uses just not worth it. It's dynamically loaded when you need to display a larger image (only if necessary). The typical lightbox when you click on a screenshot, but I hope eradicate jQuery in the future, as it was a quick fix at the time.

For the rest, a bit of code to make the request to the server and displayed in a modal label the result.

The modal popup is a project called picomodal and occupies 1,754 bytes.


Collect the information, filter it to prevent SQL injections among others and I use for the first time a distributed object caching for the results obtained from the database, which I hope to gradually incorporate in other petitions. It's called phpfastcache and it has been already commented here.


Sorry If I lost my time with this, but the result is a search engine that don't overloads the web and displays headlines in less than a second.

PiMAME: Little F.A.Q


We started the week resolving some questions you can find with this Raspbian loaded with emulators from Shea Silverman.

Here we go!

[Do not hear sound through HDMI]

Execute the following:

sudo amixer cset numid=3 2
sudo amixer cset numid=3 100%
sudo amixer cset numid=3 unmute

Edit the file config.txt as follows:

sudo nano /boot/config.txt 

and remove the # character from the line hdmi_drive=2

[I can't see the ROMs in the emulators]

Runs under the command line as follows:

sudo chmod 644 roms/*.*
sudo chmod 755 roms

Remember that you can use files in .zip although beware with uppercase extensions.

[How to configure my Xbox 360 Pad]

Edit the file advmenu.rc as follows:

sudo nano .advance/advmenu.rc

and changes from none to auto in the line device_joystick

Now install the driver:

sudo apt-get install xboxdrv

Edit the file rc.local as follows:

sudo nano /etc/rc.local

and added after the lines with # characters the follow:

xboxdrv --trigger-as-button --id 0 --led 2 --deadzone 4000 --silent &
sleep 1
xboxdrv --trigger-as-button --id 1 --led 3 --deadzone 4000 --silent &

changing *--id * by *--wid * if your pad is wireless.

NOTE: The pad will not work on menus, only in games.

[and my USB Pad]

OK. Install the driver:

sudo apt-get install joystick

With the pad connected, execute the following:

jscal -c /dev/input/js0

Where js0 is the pad 0, js1 is 1,...

In this calibration app, do not touch any buttons until prompted. First set the horizontal axis pressing back + button (0), center+button (128), front+button (255). For the vertical axis: up+button (0), center+button (128) and finally down+button (255).

[Why cant' load some ROMs in the MAME4ALL]

This version is a port of MAME 0.37b5:

If it does not work the ROM you want, try the AdvanceMAME.

[Where can I get the ROMs]

Search on the internet, or the links below as the law of your country allows it (I am not responsible blah, blah, blah ...):

[End words]

The list of questions and answers will be updated with more questions. I recommend reading the official forum to answer your questions or below in the comments.





Well, as you see, I've been away for a vacation los in a village, no internet and only my Raspi, friends, pool and party out of control :P

I programmed a script to post some articles that doesn't worked, and as I turn to go on vacation, I'll update Monday morning until Friday and will not see me here.

Perhaps I tweet something from my account, and you have the Google Docs with a list of blogs, so you know what to do while I'm gone ...

Tether Your Raspberry Pi with your iPhone 5

iphone tether

I wish I could this holiday to share my internet data mobile from my iPhone to the Pi.

These steps from Dave Conroy will help us to achieve this.

Never hurts to have this information closely. The good thing is that with this guide, do not need to run anything once you connect your iPhone to the Pi. It will automatically connect and have internet.

To do this, the first step is to install a number of packages for the Raspi to detect the device. After setting the file /etc/network/interfaces, we have internet through the iPhone in the graphical environment.

To get it from console, you must be follow a few steps more.

By the way, I recommend you to take a look at other articles he have on his blog.

Raspberry Pi at 1400 Mhz!

raspi hot

I think the max level I've overclocked the CPU has been 950 Mhz.

It's easy to do without void the warranty on the configuration set in the script raspi-config (called Turbo Mode), but there is a brave man who want blow up their Raspberry Pi (literally).

A forum user tells us under what conditions his machine has been overclocked to reach this processing speed. Want to see it?...

He tell us in the forum and did not use any active or passive heatsink. The configuration has been reached so far is:

  • ARM: 1400

  • GPU: 500

  • Core: 550

  • SDRAM: 750

  • OV: 6

He used PiBang, although I don't think is relevant. Do you encourage to do the same?...

Thank You!


First of all, thank you for the visits yesterday. About 800 visitors in a day is something I'm not ready.

Maintain a blog seems easy but search daily interesting news, images, test, translate,... is hard work without reward.

Also thank you to for supporting the site with your banner. Honestly if you live in Spain and do not want to do your life complicates looking keypads, cases or wires, the best is a pack available on their website. In a day or less you'll have it in your home, not to mention the impeccable service and warranty which commented earlier.

The supreme gratitude goes to my dear wife and those who comment, retwitt and spread news through this blog.

Now I want to make a stop along the way and discuss a few things that I have prepared for the blog:

Most importantly, minor changes like more buttons to share on social networks. Try to get other content like programming. The Google Docs come famous and I am translating into English as people demand. I think it is more successful than this blog :P. In fact I think there is no other document ON THE INTERNET like that (true story).

And most importantly, a contest. I bought a pair of Arduinos for $9 that I mentioned recently, and that you can get in this link.

If you want to join, send articles or want to change something on the blog, you know what to do.

See ya!

Windows-Raspberry Pi Cross Compiler


Cross compiler, by definition, is a compiler which builds software for another platform, not the platform it is running on. This means we can develop and compile our applications from Windows environment for the Pi.

Raspberry Pi is a powerful machine for the limited features it has. Developing software under it, when it is a simple program does not engage much difficulty or time to compile the results. But when we tackle more complex projects, it becomes rather tedious task, especially when debug any process.

The advantages of the cross-compiling can imagine: Working with the environment in which you feel more comfortable, speed development time and debugging, compiling for different machines ...

One can compile from Windows to Linux or Mac OSX, or you can compile from x86 to ARM or x86_64.

In the following link, we have the steps to configure a Windows machine and compile our projects with Eclipse. The libraries are you can buy for $ 10 or compile them yourself according to the environment you prefer (Raspbian vs Debian, arm-linux-gnueabihf vs arm-linux-gnueabi, dynamic linking to ld-linux-ld-linux vs . SO.3).

This method I want to extend it in successive post, looking for other development platforms such as Ubuntu or Mac OSX. Stay tuned.

LemonPOS on the Raspberry Pi


Maybe this is not going to interest you, but everyone knows someone who works or has a pub, bar, restaurant,...

LemonPOS is an operating system designed to make the function of POS (point of sale). Tell you why it is interesting.

The biggest problem is the industry is finding quality software that runs on a different operating system than Windows. Some companies rely on to develop their own, which is a mistake because they end up dropping out due to development costs.

As a general rule, to keep track of this type of software usually no expense spared in hardware and have a mid-range computer / high for software that just consumes memory or space.

The power consumption makes these devices to be connected throughout the day is also a detail to consider.

That's why it's a great idea to have a hardware like the Raspberry Pi, with software of this kind.

arkOS: Securely self-hosting your server


arkOS is presented as an operating system based on Arch Linux with three important premises when hosting your own server: fast, easy and secure.

The best thing is that everything is made from a specific environment that make the installation of any service easy and hassle free. It's time to go forgetting pacman and apt-get...

The functions that can be set when a server operating system are typical: web server, mail, social networking profile and your own file server on the cloud among others. It also lets you easily configure the environment to connect to internet if you have no self-control.

The system has its own control panel called Genesis that will allow us to control all aspects of the operating system without having to run any command in the terminal: System Monitor, users, applications with its own repository, plugins ...


I believe without a doubt that if you need you own server, you must choose this solution.

Download from file sharing sites (uploaded, MEGA, freakshare) on your Raspberry Pi


Today we'll see how to download from hosters like Uploaded or Mediafire

Updated July, 2017

Best of Raspberry Pi for me is saving resources on tasks that require some time to process: Modify massively thousands of files or download torrents are some of them.

Today we are going to download/upload files from sharing sites such as MEGA, 4shared or Mediafire in Raspbian or Debian based with plowshare.

What is plowshare?

Plowshare is a command line tool (CLI) to upload/download files from sharing websites such as MEGA, Uploaded or FreakShare.


  • Plowshare supports around 44+ different hosters.

  • A small footprint (few shell scripts). No java, no python! Run fast on embedded devices!

  • Few dependencies and portable. bash and curl are enough for most hosters.

  • Support for automatic online captcha solver services.


First, install the dependencies:

sudo apt-get update && sudo apt-get install recode spidermonkey-bin sxiv

NOTE: If you have premium account, do not install sxiv package.

It is necessary for some hosting the next to solve Captcha, but do not install it if you do not ask:

sudo apt-get install libhtml-parser-perl rhino

Now download and uncompress the next file from github, and run:

git clone plowshare && cd $_
sudo make install
plowmod --install

plowmod enable some hosters by default (Uploaded, Mega,...)


The command to download is called plowdown. To use, simply write plowdown followed the download link from X-Windows:

plowdown http://url_to_download

You need the X because Captcha show you a picture. There are packages that convert the image in ASCII format to be used directly from the terminal such as aview, but I have not managed to resolve none with this method.


From the desktop you can see the Captcha and solve it.

If you have premium account you don't need enter into the desktop. You can download directly from a console.

To do this, you must add the parameter -a 'user:password'. Example:

plowdown -a 'user34:1234'

We can also create a .txt file with all the links you want to download and invoke it as follows:

plowdown -m downloads.txt

Karaoke on Raspberry Pi


One of the biggest frustrations I've had with the Pi is to be able to use it as karaoke machine. I have tried several methods but the guys from Pi-Fun seem to have discovered a way to make it work, but the method is somewhat complex...

The basic problem is to hear the microphone through the TV and play the .kar at the same time. The system failed but now has been updated the sound drivers on Raspbian and seems now it works.

The method requires two SSH connections and install a few packages. Fun is guaranteed.

Download music from GrooveShark (CLI)


Today we will learn to download music from Grooveshark with the command line (CLI)

People loves music and loves to accumulate hundreds of thousands of songs on their hard drives. Today we have services like Spotify or GrooveShark to listen online what we want without having to store them on our HDs...

...but if you are human and you still want to store it, we will see a way to download music from the command line, as the pros likes ;)

You must to download the following code from the GitHub repositories:

git clone

We entered the Python folder and find the song you like writing ./ 'query'

Example: ./ 'drive by'

Example of downloading a song from the command line

That's it. Easy as they like to newbies (and more to the pros).

Raspberry Putting to work


Every programmer has ever met with some repetitive work to do modifications to several hundred files or having to generate scripts to download something massively for hours.

The Pi has the power of a Pentium 300 Mhz, but consumption and environmental impact is minimal.

Patolin, user known for its excellent tutorials, shows the creation of a Python app which helped him to extract information from a website to a database and saving which earned him execute that script on a Raspberry Pi.

Available a few days ago but has been slow to upload their image. Before the jump to what will be version 3.2 of this great Media Center, I recommend to all fans of this distribution to update. I pass on to detail the reasons...

  • First, boot speed. They have a problem that could slow your boot, and now is completely fixed.

  • Speedup fanart and thumbnails loading.

  • Network caching.

  • GUI optimizations (on RPi showing the Systeminfo output should have much lower CPU usage now).

  • Improvements,fixes in Avahi/Zeroconf and Samba.

  • OBEX protocol support (Bluetooth) for file transfer.

Replace Dropbox with BitTorrent Sync

bittorrent sync

I have recently changed service cloud storage. The 7 GB available in Dropbox had I been outgrown. I changed it to Box and now its 25 GB I haven't got storage problems...

Interestingly I did not think to use the Raspberry Pi to store and sync all the files I use most on my computers, whether PC (Windows, OSX, Linux), tablets or mobile phones.

Jack Minardi gives us this tutorial to have synchronized the files at any time by the Raspberry Pi as a node.

Notice that it has nothing to do with sharing your files in the large network of torrent there on the internet, but to use this protocol to keep our files online.

Learn to emulate a Macintosh from Raspberry Pi with vMac

Mini Mac

1/3 the size of an original Mac with a Raspberry Pi inside

Yesterday was the most read news on the Net: John Leake has built a Macintosh scale with patience and has incorporated a Raspi to run under Raspbian a Macintosh emulator called vMac.

Would you like to run the emulator and see how is it?. Follow me...

Do you want one? Me too...

[Files needed]

First download the emulator and necessary ROMs. Calm down, you can find it in this post.

Download updated January 24rd, 2014: Mini vMac 3.3.3 emulator

Download: Mediafire > (ROMs)


Nothing easier that unzip both files in the same directory and rename it from vmac.rom to vMac.ROM.

tar -xzvf minivmac-3.3.3-larm.bin.tgz
mv vmac.rom vMac.ROM

Start the X if we are not already and open LXTerminal. Now type in the directory where we have all files, the following:

./Mini vMac

[Install the Operating System]

The first thing that appears is a screen indicating the disk image is missing.


We will open the directory where the files is located with the File Explorer (PCManFM) and drag it to the emulator's window the file hfs20M.DS.

Now you'll be asking installation disks. Go dragging to the window the files, starting with Install 1.image.

Once the process is finished, you will have to restart and here we are.

And the winner is... OpenELEC!


Most of us have a mini SD card ready as a media center. Curiously Raspbmc and Xbian always are the new handsome kids on the block. I read daily and I always wonder the same thing: What's wrong with OpenELEC? Let's see some info to know what's the best of the best...

OpenELEC, the ugly duckling that nobody wants has spread its wings, has faced his brothers and declaring himself like the winner. have compared again the latest versions, especially of Xbian 1.0 Beta 1.1 (July 14) vs OpenELEC 3.1.6 (August 20). The last one has optimized a lot their system.

If you want my personal opinion, I tested these three solutions since I have the Raspi and I always come back to OpenELEC. There must be a reason. By the way, What's your favourite distro to use like media center?

rPlay mirroring with Apple devices and Raspberry Pi


I can not be more excited!.

Think I mentioned, but since I sold the AppleTV , the most feature I miss is the mirroring function, useful if you want to duplicate on another screen what you are doing on the iPad, iPhone or iMac.

Luckily VMLite guys are carrying this functionality to the Raspberry Pi, with a fairly promising.

I have a beta private copy and teach you how to install it and their functionalities. Do you want to see it? Let's go!...


rPlay supports AirPlay and AirPlay Mirroring. For iphone 4 and iPad 1, you can't do AirPlay mirroring, but you should be still do AirPlay for Photos/Music/Videos. For iPhone 4S and iPhone 5, iPad 2 and above, you can also do AirPlay mirroring.

It's a daemon running on boot once you've installed. You need to download the application, change the system memory to give the maximum to the GPU and enter your license key.

[ How can I get a license key? ]

Easy. Now It's free. Just register a user in the forum and ask for it. In a short time you will get in your mailbox account with instructions needed to make it work on your Pi.

Link: Forum

[ Prerequisites ]

Update the firmware of your Raspbian with

sudo apt-get install rpi-update && sudo rpi-update

Now give more memory to the GPU with sudo raspi -config. The model B needs 256 MB and model A 64 or 128.

Now install the dependencies and the software with:

sudo apt-get install libao-dev avahi-utils libavahi-compat-libdnssd-dev libva-dev youtube-dl
sudo youtube-dl --update
wget -O rplay-1.0.1-armhf.deb
sudo dpkg -i rplay-1.0.1-armhf.deb     

We go from any computer on the same network to the browser and type: http://IP_PaspberryPi:7100/admin or you can start X from your Raspbian with Midori and go to the next url: http://localhost:7100/admin (user admin user , password admin).

There you can find a front end to configure some parameters. We need to add our license key at the end of the page. You can also do it directly modifying the file /etc/rplay.conf

Now restart to get rplay run automatically the daemon.

If we want to stop/play the daemon:

sudo /etc/init.d/rplay start
sudo /etc/init.d/rplay stop

[I want to uninstall rPlay]

sudo /etc/init.d/rplay stop && sudo dpkg -r rplay

A picture speaks a thousand words: I present my first Youtube video related with the Pi. I show you several features about rPlay to give you an idea of its actual performance so press play and enjoy!

Partition backup with fsarchive (Linux)


Bart has learned the lesson. Now it's your turn.

Do you have an USB or mini SD with about 64 GB+ data that just take a few gigabytes and you want to make a backup with dd command?. The image will fill those 64 GB but you are occupying just the 1%.

The solution is to use the command fsarchiver and just copy the data, not the free space. Would you like to know more?...

This is the stage: A flash drive or SD card with about 64 GB and only 2 GB usable with data, but we want a backup of the entire system because we are testing various configurations and files.

Our solution is to make a complete backup of that specific partition. As a rule people do it with dd command and goodbye problems. But copy every bit, even free space, so you get a file with all the capacity. What a waste!.


Fsarchiver is a tool for cloning hard drives very efficient. Supports the use of multiple cores, so we obtain our copies generated in seconds. It's the continuation of PartImage, created by one of the authors but rather enhancing it. It supports many file systems, including NTFS, ext4, btrfs and reiser4.

Other notable features include compression multi-threaded of the disk image files, along with file-based images(instead of blocks) to improve compression and ignoring the clusters unused.

[ Installation]

You can find the application in the official repositories of any distribution. On Debian is installed with sudo apt-get install fsarchiver

[ Use]

Insert your flash drive, HD or SD card and run the following to see a list of available partitions on your computer:

sudo fsarchiver probe simple


My current partition table

The best way to see its use is with an example. In my case, I want a copy of the partition sdb2:

sudo fsarchiver savefs -j4 -o backup.fsa /dev/sdb2

Let's see the parameters passed to the file:

  • -j4 indicates I want to use my 4 processor cores. To know how many cores do you have, run: grep -c 'cpu cores' /proc/cpuinfo

  • -o overwrites the output file.

  • backup.fsa is the file name with the cloned image of the partition. You must use the .fsa extension.

  • /dev/sdb2 is the partition I want to clone.

I created the file in a short time, everything will depend on your computer.

NOTE: You can add the -zX parameter to compress the image, where X indicates the compression level 1-9. To see these levels, read this section.

As an additional note, if you want to backup the system known as MBR, will be sufficient to run the following (now we would use the command dd):

dd if=/dev/sdb of=sda-mbrl bs=512 count=1

[Restore a copy]

Damn! My OS doesn't work with the actual configuration!. Hey! No problem. Fortunately I kept a copy. I will restore it with:

fsarchiver restfs backup.fsa id=0, dest=/dev/sdb2

The option id=0 indicates that you restore the first file system found.

Obviously there are many other parameters, but these are enough. If you want more information I refer you to the following links. Thank you!.

MicroXwin on Raspberry Pi

Xorg X11 vs MicroXwin on Raspberry Pi

X Windows is a network oriented and client-server design with the X server responsible for all graphics operations.

MicroXwin is binary compatible to the Xlib API. However it is neither client server nor network oriented. Graphics operations are implemented in the linux kernel via a kernel module and makes this solution smaller and faster than traditional X Windows.

Why should you consider using MicroXwin.

  • Snappy GUI - MicroXwin has 2X times faster graphics, faster event handling, low latency and low round-trip delays.

  • Lower Memory Usage - MicroXwin's kernel based X server uses < 1/2MB versus 29MB used by Xorg's frame buffer X server.

  • Compatibility - MicroXwin is binary compatible with standard X11 at the Xlib layer. So you can run all the standard applications and window managers.

Now is available on Raspberry Pi. If you want to test a demo, download from the link below.

hydrophobic is the fear to water, and in this case from what I understood, the repellent is because the angle of a water droplet exceeds 150 grades and with this compound the surface would have an angle much less.

SDL2 for Raspberry Pi at last (binaries inside!)


For months I have wanted to make a review about engines/libraries/frameworks to develop video games. Nobody in their right mind today would develop a game from scratch.

SDL is the most famous library to develop video games, but also slower when running it on the Pi, until now...

This second version really takes time with us, it was not until a few days ago that it has received an update to work on the Raspberry Pi properly. The version that will be compatible with the numbering 2.0.1, but there is a user that has compiled this library (I leave the binaries along with the headers at the end of this post) in the official forums.

  • Work without the X.Org server

  • OpenGL ES 2.0

  • ALSA based Sound drivers

[ Raspberry Pi ]

Maybe you don't know what the hell is a Raspberry Pi. You can get an idea in this link. What is certain is that it has changed the way we view the electronic science, programming and Linux for many people and kids. We have opted for it, even Google donated 15,000 units for schools in the UK and has created an environment for web developers called Coder.

It has got rivals, but has never fallen from his throne. I would have never imagined we could do so many things with it: Home Center that plays Full HD, music and photos, retro game console, downloads/files/web/print/database server, video surveillance and security systems, home automation, robotics, teaching, VOIP, video screen for demonstrations, play content from your phone to the TV, weather station and so on. All this in the hands of anyone who wants to take forward and yes, perhaps you can do it with your computer, but not with a power consumption of a few [dollars,euros,pounds] a year.

[ Mission accomplished on the blog? ]

Of course not. There is still much to do and learn. Expand a little more the other sections, improving the usability of the web, my own tutorials...

The blog was the continuation of Google Docs, updated daily and as I said on another occasion, is the file with more documentation and links collected about Raspberry Pi in the World.

It's pretty sacrificed get a blog and update it almost daily. It's a challenge finding articles, projects or new that are not cover in the main channels, but I'm happy with some tutorial that has become famous this blog, like the CuboPuntes or the RetroPie guide, which continues to receive visitors. The English translation help me to improve my knowledge of the language (no one has complained yet) and something you did not expect: comrades. People with your same passion we discussed all that excited to do with this plate so small and that after two years since its launch continues to surprise us.

Mupen64Plus - N64 Emulator for the Pi

Nintendo 64

Not long ago we discussed the possibility of emulating the Nintendo 64 in our Raspberry Pi.

Many thought it was not possible, but a user began to rewrite the code to be executed on the GPU directly thanks to OpenGL ES 2.0 and now we can see ourselves the result...

We have a repository on Github with Mupen64Plus emulator source code. If you want to try before you will have to solve the following dependencies:

sudo apt-get install libsdl1.2-dev

Now clone the repository with:

git clone

Enter into the directory and run: ./

With the compiled binary, we search a ROM and put it in the Pi and run: ./mupen64plus /home/pi/mario.n64. If you haven't got any available, you can try a demo with: ./mupen64plus m64ptestrom.v64

Trackers: Review on Raspberry Pi

music tracker

Do you remember Scream Tracker?

This post has brought me many memories. I want to dedicate it to my friend Paco Rodríguez , a great music lover who has decided to compose in the Raspberry Pi.

Whether you like to compose or if you've never tried or, why not, you want to listen true masterpieces, keep reading on...

Necros / FM - Revelation

This morning I dedicated to collect information about this possibility and compose your own music. Trackers allow us to create music with little knowledge of music theory.

The song you hear in the video on these lines belongs to a composition created with a music program called Tracker.

As we read in the Wikipedia Music trackers (usually referred to simply as trackers) are a class of music sequencer software used to create and edit module files; they allow the user to arrange notes (pitch-shifted sound samples from the module) stepwise on a timeline across several (traditionally monophonic) channels.

2nd Reality - Purple Motion - Unreal - Impulse Tracker

Chip Tune (as it calls itself now) is the progress of this king of composition. More than once we found a .S3M * or *.MOD file if you take time playing with computers. It seemed incredible that any guy could compose that way.

I leave you with a list of links if you want to practice and who knows, perhaps in a future you are a master of the Chip Tune. winking_tongue_out

Aurora.mod. A classic.

Tips Book on (Spanish)


Sorry, this post is only in Spanish.

Starting with a Debian OS


When we have enough experience to manage with the Raspbian operating system, it's time to become independent of it. Here are some tips to make you feel comfortable with other Debian based distribution, in this case we will use PipaOS.

These tips are not so easy to find. That is, I'll teach you not to configure a static IP or your WIFI dongle, for it we already have hundreds of tutorials. Let's begin:

[ Expand the partition ]

The image usually comes with a size that does not correspond to the full space on SD card.

In the special case of PipaOS, comes with a partition at the end that we will erase previously. If not your case, pass the next point to expand the partition.

Update Feb 9, 2014: Skip first step if you have 2.3+ version.

1) First enter parted with:

sudo parted /dev/mmcblk0

print <- show partitions rm 3 <- delete partition number 3 quit <- exit from parted

2) Now we get into fstab and remove the last line: sudo nano /etc/fstab

To expand the primary partition, automate the steps thanks to a script not to complicate a lot:

sudo apt-get install parted
sudo wget --no-check-certificate
sudo chmod +x rpi-wiggle
sudo ./rpi-wiggle

Press ENTER to restart and when finish the repartitioning, you can delete the file and if you want also parted with: sudo rm-wiggle rpi && sudo apt-get remove parted

NOTE: The partitioning process can take several minutes depending on your SD card. Please wait to shell prompt.

[ System Updates and critical applications ]

The second thing we do once we have expanded the file system is to install a number of programs and update the distribution. Add or remove applications freely think you will not need.

sudo apt-get update && sudo apt-get install mc git-core ntpdate ca-certificates build-essential keyboard-configuration locales

If you want rpi-update to kernel's updates:

sudo wget --no-check-certificate -O /usr/bin/rpi-update && sudo chmod +x /usr/bin/rpi-update

sudo dpkg -i *.deb

[ Alternatives to take into account ]

It may be the case that some tools are not installed. If you intend to install the bare minimum, you might want to achieve our goal without "dirtying" the system. Here are some commands that will help you:

ifconfig = hostame -I (letter I uppercase)

Problems with wget y https: add the parameter --no-check-certificate

[ FAQ ]

No space left on device

It is because the temp folder is in the RAM and has no space for the operation you're running. One way to fix it is:

sudo nano /etc/default/rcS
change the last line

Reboot and try to reinstall the package again. Go back to the file and change again with RAMTMP=yes when finished

I want autologin


Edit sudo nano /etc/inittab and add to the line 1:2345:respawn:/sbin/getty 38400 tty1 a #:

#1:2345:respawn:/sbin/getty 38400 tty1

Add below:

1:2345:respawn:/bin/login -f sysop tty1 </dev/tty1 >/dev/tty1 2>&1

Where sysop is the user name (on PipaOS case).

To be continue...

AEROS Beta 5 available

AEROS is a hybrid distribution of AROS and Linux (in the moment debian 6.0 for X86 and 7.0 for ARM is used) available for ARM and x86 systems.

I posted recently about this operating system. The bad news was that only allows registered users to download (I think it requires registered user make a small donation).

The good is that it has been released beta 4 to the public, and now we can install applications through the application lx included, something we could not to do before.

The new beta is now available as ARMhf like Raspbian or Debian Wheezy.

Who is encouraged to try? After watching the video, we see that the OS goes to the right way.

Minibian 2013-10-13 available


New updated version of the earlier appeared three months ago that we did echo. A few changes to note except the update to kernel 3.6.11+ #538 and updates pertienentes of her older sister. As features to consider, I would highlight:

  • Fast boot

  • Fits on a 1 GB SD card

  • Ext4 file system with disabled swap

  • Sshd enabled by default

  • IPV6

We recall that the user is root and password raspberry. raspi-config not installed by default, but can be fixed with apt-get install raspi-config

As a personal note, this version is faster than the previous one.

Introducing SmartBot: Raspberry Pi compatible robot


SmartBot: your Smartphone robot

Everyone may think that the new revolution is 3D printers. I think we forgot something that surely going to explode from NOW. I speak of the world of robotics to anyone.

In this case, having a mobile making "brain" of the beast, you can control a robot with programmable features as discussed below...

The next revolution is called SmartBot. It connects to your mobile phone via the audio jack (among others) and to use all the advantages of your mobile device (GPS, BT, accelerometer) to control the base presented.

Battle robots, games, learning or using it as a pet. The possibilities are endless and the most interesting is that it is programmable and has its own SDK. We can build as you will see in the video presentation an Arduino or other development board.

It has a programming system based on script. I invite you to visit the website to see all the features we can get. Its cost around 150 euros.

Happy Friday!

OpenELEC with steroids by MoDi


Media Centers for Raspberry Pi is shared between Raspbmc and OpenELEC. The trouble is that we have to preconfigure certain parameters whenever you install from scratch because of a new version and sometimes is rather bored do this task.

Fortunately, thanks to spanish user MoDi, we have a custom OpenELEC build that you will not have to configure, and add at our disposal an XBMC overclocked with everything you need to enjoy streaming, BitTorrent and much more...

This compilation is based on builds made by the user RBEJ and is based on Frodo (v12). It comes with a 900 Mhz overclock. In the forum you have detailed instructions and comes loaded with the following addons:





  • XBMC Library Auto Update







  • rtmpgui+










From here we thanks to Modi and hope to continue to improve this compilation.

EmulationStation + Omxplayer = simple media player


The truth is that I found this initiative pretty ingenious to get EmulationStation as a launcher for the omxplayer. Sometimes we do not need XBMC if what we do is just watch some movies or listen a music list...

Perhaps it isn't the best choice, since you have to manually create links to each file you have on the file gamelist.xml (although you could automate it), but it strikes me that for some project that shows by default a simple media list, it might be just ok.

Forum: > EmulationStation + Omxplayer = simple media player

iTunes Server on Raspberry Pi


Many of us use iTunes as an audio player. The trouble is that not always have ALL the songs we have available, and the best would be an external hard drive with songs repository to access remotely from our iDevices to them.

Raspberry Pi will help us on this mission...

forked-daapd is an iTunes music server, which can be controlled by Apple Remote on iPod/iPhone or by an app like TunesRemote+ on Android. You can also control it via iTunes itself. It can output audio locally or to Airport Express compatible devices.


With apt-get:

Add the next line to /etc/apt/sources.list:

Now: sudo apt-get update && sudo apt-get install forked-daapd

Edit /etc/forked-daapd.conf restart the server with sudo /etc/init.d/forked-daapd restart

[Pair with Remote]

Make the file pass.remote on your Library with two lines: one with the name of your device and another with the PIN that Remote give to you when trying to pair with your Library. That's all!

For more information you have the forum and the project readme below.

KANO: Raspberry Pi Kit for kids in the house


When my daughter has a few more age, I will teach how to program but I don't want she was be a programmer. I think it's the world's sacrificed profession. The kit that I show below is a start to learn not only how to program, but to bring the Raspberry Pi to the age for which they were designed.

I'm sure this kit from Kickstarter will get financiation before the end of the week (It just starting).

Comes with its own operating system, based on Raspbian I guest, with some changes in the graphical environment. Perhaps Santa bring to your child one of those.

Wolfram API on Raspberry Pi


Seems like yesterday when we reach 100K visits and we exceeded 130K. I'll have to start thinking about what to gift when we reach 200K unique visitors :)

I usually put news that you can't easily find if you daily blogs, but the news I found today is very interesting: Raspberry Pi Foundation has announced a partnership with Wolfram Research to include Mathematica and the Wolfram language.


Almost any workflow involves computing results, and that's what Mathematica does from building a hedge-fund trading website or publishing interactive engineering textbooks, to developing embedded image-recognition algorithms or teaching calculus.

We have it in the Raspbian repository and you can install it with sudo apt-get update && sudo apt-get install wolfram-engine. It may take about 45 minutes, so be patient. If you don't want to install it, you can try in the next version of Raspbian.

I think this will bring a new world of possibilities for our Pi and interesting projects will be born here, so be prepared...

RACHEL Pi: Get all the knowledge on a SD Card.


I had this link saved for review and today I have taken a look.

It is a distribution that act like a server and show to the machines that connect to it from a we browser, various information sources such as Wikipedia or the Khan Academy courses. All offline and only need a SD card with 32 GB.

RACHEL (Remote Areas Community Hotspots for Education and Learning) gives more value to have a Raspberry Pi and have it as a server.

It's for schools with few resources where they can't get an internet connection or it's very slow.

Updates for OpenELEC & RetroPie


Today I would like to thanks the people who contact me by e-mail or Twitter for congratulating me on the blog and ask some other things about the Pi. Weekly I receive many emails and I try to answer them all.

Today's news is that we have updates from two of our favorite distros: OpenELEC and RetroPie...

The latest version of RetroPie 1.9.1 fixed "freezing" bug. Let's remember that changes in version 1.9.0:

  • Added emulator Mame4All-RPi & Mupen64Plus-RPi

  • Added configuration script to the "splash screen"

  • Added configuration menu for RetroArch NetPlay

About OpenELEC, currently is under maintenance and I could not access the features of this new version, but you can download in the link I left or you can enable the option "automatic updates" from the OpenELEC menu.

Synergy: One keyboard and mouse to rule them all


Synergy is a client-server application that allows us to control with a keyboard and mouse several machines. Imagine you have an iMac, a PC and the Raspberry Pi. Installing this app allow you to use the keyboard and mouse of one of the teams in all three, so no longer need three keyboards and three mice and save you to keep your desktop clean (which you needs).

This solution is perfect especially for owners of a Pi, and it's not difficult at all. Just installed the server program on a desktop computer and the client on the Pi with sudo apt-get install synergy

It's explained more clearly in the next blog.

After spending so much time reading about Raspberry Pi, I think we are gradually seeing what the majority use is given are: Media Center, server, emulators for retro systems and Ambilight.

Today's post is dedicated to the brave who want to learn to build your own Ambilight system...

And nothing better to do that than with some videos that leave me impressed.

In this first whole process is about assembly of LED strips on the TV and installing Raspbmc.

In this second part we configure the necessary files for perfect synchronization between the strips of LEDs and the OS.

Doom's Aniversary (20 years). Celebrate it with the Pi


It seems like yesterday, but Doom has 20 years on his back

Many of us have thankfully grown in a time of revolution in video games. There was innovation in programming methods to stand out in an emerging market like PC video games. Doom was the star on the fps genre.

Today we're going to enjoy this game on the Raspberry Pi...

I remember I bought a Sound Blaster Pro to a friend to fully enjoy this game on my 486 DX2 - 100 Mhz. No one can forget the soundtrack that accompanied us on each stage.

Let's Rock! (ups!)

We felt powerful with that shotgun or the chainsaw. The good news is that there have been many ports along the years, and our Pi could not disappoint us.

The best existing version to run on our beloved Pi is Chocolate Doom. You can download from the Pi Store. This version supports Dispmanx under SDL 1.2, using the GPU acceleration to play the game.

Overclocking on the Pi

rpi overclock

We have already talked about this twice on this blog. The Wikipedia explain as the process of making a computer or component operate faster than the clock frequency specified by the manufacturer by modifying system parameters.

It is a fascinating world that not all people make a practice. The Raspberry Pi Foundation allows us to implement a default oc setting from the application raspi-config.

In my case I always have the Raspi overclocked to 950 Mhz, but I have two sinks and allows me some peace of mind.

Today I read in the forums that the user JoJo_ReloadeD has come to put the CPU to 1133 Mhz with this same system.


Hot spots in the Raspberry Pi

Curious detailed heat released in the power connector.

The values in the config.txt file are:

over_voltage=12 # Although in theory the maximum value is 8, 12 also works ;)

Top Operating Systems recently updated (December, 2013)

sd pile

Today I have started to visit the different Operating Systems that we can get to the Raspberry Pi and I've made a list with five ten that OS which have been updated in recent months and those who have long not been updated. Do you have curiosity?...

DISCLAIMER: I mean built images dates.

We all like to get the Operating System with the latest patch updates, software and repos. In our world, not always possible if you have a distribution created by a user independently or with a specific goal. So we have a hundred of them, but in the end many end up in oblivion.

You can find a candidates list in the Operating Systems section inside my Google Docs. Interestingly on the official website are not updated links in the downloads section of any of them.

The list I put below are OS with a .img already created and does not need compilation. Perhaps some are rolling relased.

Those who have long not been updated are:

I hope this list helps a little more to your choice of Operating System for your Raspberry Pi. I'll update it when I feel or any of my dear readers asks me.

About pipaOS, soon you will have news here about this Operating System created by a Spanish.

HOWTO: Bluetooth with OpenELEC


Today we'll see how to pair BT devices with OpenELEC

The new OpenELEC 3.x version has not only improvements about performance and speed. One of the features that best took into account has been setup any Bluetooth easily (keyboards, mice, speakers, headphones or mobile), and all through its menu.

I want to show you how to set up one of these devices (in this case an Apple Wireless Keyboard) with OpenELEC 3.2.4 on the Pi


Before the end of the year I'd planned to make a tutorial. I wanted to see if this new version is easier than before. The answer is yes.

The first thing to do is buy a Bluetooth module if you have not one already. You can purchase the Conceptronic USB Bluetooth which has been tested in the online shop through this link in Spain. In my case I'll use one from Trust:


It has given me more than a headache on the desktop, either with Windows or Linux... but with OpenELEC on the Pi has worked for me from the first time.


Raspberry Pi ready to pair... the lucky guy is an Apple Wireless Keyboard

As I have mentioned in the beginning, I will connect the keyboard from my iMac. I had trouble with that in the past too.

The first will be install OpenELEC (the latest version at the time of this article is the 3.2.4) on a SD card and plug your BT adapter (make sure you get enough power) before boot the Media Center.

Now we'll go to System > OpenELEC menu as I show you in the screenshot below:

Press the image to full size

The system will be loaded as modules in the kernel to use your BT adapter. From the menu on the left, we will access to the Bluetooth section and there will appear different BT devices. To setup the keyboard, you should turn it off by pressing the power button for 4 sec. and turn it on by pressing it again another 4 sec. A green light will flash and the keyboard magically appears...

(MAC Address hidden to respect devices anonymity)

Then we select the keyboard and press ENTER or click with the mouse. Then it ask what we want to do:

Rarely in life you can trust like in this case

Select Trust and connect to not ask us again in the future to match again.

Now depending the device you want to connect, will ask you for a PIN code which is usually 0000 for mice and headphones, or 1234.

PIN Code Request

Now the difficult part:

  • In OpenELEC you must write 1234 and click on the button Done.

  • On your keyboard you must press 1234 and hit ENTER.

With this you will have already paired your device forever with OpenELEC as you can see in the capture.


Fuck yeah

NOTE: No device was forced to marry with the Raspberry Pi after this tutorial. For this couple, they have some dates but they were distancing until he returned to his former partner (iMac 27", just so you don't say that size does not matter).

News this week

EveryDay Practical Electronic

This week we had some movement in the Pi World. I have holidays and buying gifts but I've compiled some of them for you. I also just observed that I have exceeded 150K visits in less time than I expected. Thanks for take into account this blog to keep you inform of news about the Pi. I got news that I can not reveal until January yet, but it will give more international projection to the blog. Let's start with the news...

  • Raspberry Pi has become the "toy" fashion, and many magazines from the electronics sector have regained benefits from articles that talk about it. EveryDay Practical Electronic is one of them. I leave an article from the last number for those who want to see and if you want, purchase. Download:

  • New Raspbian, Raspbmc and Arch updated images that you can install via NOOBS. More information on the official blog. Link:

  • Special mention deserves Raspbian, which has been updated and some of its features are: new firmware 3.10 kernel, X accelerated driver included and enabled by default, Mathematica and Wolfram language installed by default, Scratch and PyPy updated, new V4L2 camera driver and package v4l-utils updated. Download:

  • One of the problems we have on the Pi is the limited power it has for web browser. Midori which is the default browser is not the best alternative, but thinking about this someone have been proposed to develop a browser, called Web for now, in order to browser according to our Raspberry Pi specifications. For now it is quite unstable, but if you take a chance in the next link you have the instructions to install it. Link:

My Google Docs hacked (Holy Innocents' Day)


The worst that can happen is that someone steal your Gmail account with all its consequences.

This morning I woke up with several emails from users telling me that my Google Docs has been compromised by a hacker group known as Al Quadim. They have write the following message:


Now I'm a little nervous. I'll see if Google want to reset my password. I wish someone in the comments to tell me if you has been in the same situation. I will keep you informed.

NOTE: Today is like the April Fools' Day in Spain. Sorry for the joke.

Streaming PC Games to Raspberry Pi with Limelight-Pi


The PC users with nVIDIA graphics accelerator are in luck. If you have a GPU of the GTX 600/700 series, you can send your games and play them streaming through the Raspberry Pi...


Limelight is an open source Java implementation of GameStream nVIDIA, but built for Linux/OSX/Windows.

Limelight Pi is still in a very early stage, but will transmit your Steam games to your TV through the network with the Pi.

Maybe is not a Steam Machine killer, but comes close.

Updated: A user has tried and it works!. He recommended that we install to solve input and audio problems the library libopus-dev. Thanks Felix Piechaczyk!.

Raspbian minimal: What's your choice? (Part I)


Sometime as developer or admin with expertise, we need a distro with a few installed packages and a bunch of free RAM. In this case, we can use a Raspbian minimal. I cover on this article two of them.


The main focus is to have a small, updated and stable distribution that is fully compatible with official Raspbian "wheezy" image, without GUI and unneeded tools.

MINImal raspBIAN image for Raspberry Pi (Minibian)


Last file uploaded: 2013-10-13-wheezy-minibian.tar.gz (188.5 MB)

Login: root | Password: raspberry

Some useful commands to take a look. Click to full size


  • Kernel 3.10.25+ #622 ARM HF (Hard Float)

  • 22 secs boot

  • 583 Mb disk space used

  • Fit on 1GB SD Card

  • Optimized ext4 file system with swap disabled

  • Targeted for embedded or server applications (NAS, Web server, electronic applications)

  • 100% full compatible with official release

  • DHCP client enabled

  • SSHD enabled

  • 45 Mb RAM used after boot

Notes: No desktop environment installed, as usual on this kind of distro. build-essential is not installed (60.5 MB of additional disk space). config.txt only with the option to set GPU, but you can fill with others as you can see on raspi-config is missing. camera-utils is installed by default.

Click to full size


  • 3.6.11+ hardfp kernel with latest raspberry pi patches

  • Disabled incremental updates, means apt-get update is much faster

  • Workaround for a kernel bug which hangs the Raspberry Pi under heavy network/disk loads

  • Latest version of the firmwares

  • Fits 1GB SD cards

  • A very tiny 118MB image: even with a 2GB SD there is a lot of free space

  • The clock is automatically updated using ntp

  • IPv6 support

  • ssh starts by default

  • Just 14MB of ram usage after the boot

Notes: The author cover two versions: soft or hard float support. config.txt have several default options. Boot process is faster than the first Minibian commented before. We have a swap RAM partition, but you can disable it to reclaim RAM.You need to use gparted or another similar app to resize the partition, because there is a swap partition at the end who doesn't allow to resize the first. You can delete it with the next commands anyway:

parted /dev/mmcblk0
print <- show partitions
rm 3 <- delete partition number 3
quit <- exit from parted

On both distribution raspi-config is missing, but you can install it with the next commands:

echo "deb wheezy main" >> /etc/apt/sources.list
apt-key add raspberrypi.gpg.key
apt-get update && apt-get install raspi-config -y

The Wolf of Raspberry Pi


Higuer!, but beware of the roof!

I feel like Dicaprio. Several users have linked an article on my blog here and the num. of visitors has grown as you can see in the graph. I'm still freaking out!. Thanks!

Clearly that will not be repeated again, but has encouraged me to make an article that many people have asked me by e-mail: Review of the RetroPie guide I published in March last year and possibly the article with more visits I've achieved since I started the blog.

So keep an eye this weekend...

By the way, we're very close to 200,000 visitors. There will be surprises and contest!.


Nintendo 64 emulator branch master updated! (binary included!)


Yesterday the Mupen64Plus-RPI Emulator for the Pi was updated. It seemed incredible that the Pi could move the emulator with the ease that it does, but we see that almost nothing is impossible...

Super Mario 64 on the Raspberry Pi

Now his author is working on a wiki to adjust the configuration file according to the game. By the way, if anyone has any list and wants to share, I leave the forum link below...

If you are interested to compile it, you have the steps in the post that I published here.

Framework to control Raspberry Pi: WebIOPi


Still sick, but today I woke up with a little encouragement to get some information that seems interesting to the blog.

This time, I found a very interesting framework with which we will be able to have TOTAL control of our Pi. Do you want to see more?

WebIOPi is not updated in a while, but it's worth bearing in mind. Let's see what we can do with this framework:

  • Control, GPIO debug and use of sensors from a web browser or any application.

  • Written in Python and using Arduino syntax.

  • Support serie/SPI/I2C ports with a list of functions to control more than 30 devices.

  • Client HTML + Javascript to create a Web UI.

...and much more that you can find in the link.

Well, I'm going back to bed!...

Happy Birthday, Mac!


Today is the day that Apple introduced to the world the first Mac 30 years ago. My tribute will be to review and emulate a Macintosh with the Raspberry Pi with the vMac emulator...

I leave my MSX and bought a PC 286 directly. I did not even know what a Mac means when Amiga were the best and the PC was still expensive computers. I grew up with MS-DOS and Windows without knowing the rivalry between Mr. Jobs and Bill Gates, and I thought that the mouse was invented by IBM.

Over time, we must recognize that Apple has had much to do with the advancement in the digital age we have had in the last 30 years.

I leave the link to install the emulator, which I published in his day on this blog.

Power Saving Tips


The resource-saving energy with the maximum use of the power of the Raspberry Pi is something that any of us obsessed. The power to control every bit or volts is sometimes even vital for our projects.

Sunday is a great day to learn a little about energy savings thanks to Baba AweSam Blog. If ypu don't use the USB connectors, you will learn to eliminate it from system for projects requiring the minimum amount possible.

PiCAST 2.0 out!


Chromecast takes time with us. It is a technology that like to us, but it has not been implemented everything would have liked to Google.

PiCAST is an alternative to this device (or so intended), but it was difficult to configure and even received money from user. Its creator now shows version 2.0 to amend past mistakes.

Now we have the opportunity to download and run the installer with the following statement:

chmod +x ./

Presumably we can listen to music, open a web browser and watch videos. I have not tried and if anyone does, I'd like you to comment below.

Mic on Raspberry Pi


Test Labs

Don't know if happen to you that sometimes you have many things to do but an idea arises, an email from someone, something you think you can do, and leave it all to get to it.

That's what happened to me today. I wanted to test a microphone on the Pi and I'll do it. Will it work?

I have one that comes with the Singstar PS2 with an USB adapter. Karaoke is one of my passions frustrated.

I remind you that the Raspberry Pi has no microphone input and the only way to try one with Jack connector is buying a external USB Sound Card.

The first thing we have to do when Raspbian boot up is to check if any microphone is detected. There are many ways to do it, but I remember now this:


Mic detedted!. Press to full size.

As you can see, has been detected in the device 006 a Microphone Sony SingStar USB.

Now let's see where it has been placed in the list of sound cards (the system detects it as a sound card):

cat /proc/asound/cards

Card num. 1 is a USB-Audio - USBMIC. Press to full size.

With that information we can now launch a recording program. I'll use arecord that comes installed with ALSA utilities:

arecord -f cd -D hw:1,0 -d 20 text.wav

With this parameters we recorded with CD quality for 20 seconds a file called test.wav, using the hardware of the card 1 (microphone).

To play the sound, with a simple aplay test.wav is enought. If you don't hear anything, in advanced options with sudo raspi-config utility you can change the audio output jack to HDMI and vice versa...

ADDITIONAL NOTE: If after the first record we detect that the recordings are incorrect, we have to disable the USB 2.0 driver to use the USB 1.1. To do this, add the file /boot/cmdline.txt to the next line, to ensure that the recording is done perfectly:


Happy Friday!

Mr. Silverman need to know how this new version behaves, so if you test, contact with him to tell it's amazing.


PiCore 5.2 for Raspberry Pi


Today I wanted to write about Picore, a distribution created by Robert Shingledecker running directly in RAM. Yesterday 5.2alpha1 version was released. I have tested it for you.

Nobody complains that there are no operating systems for our Raspberry Pi. Almost all of us use Raspbian, but gems like this open our minds to explore alternatives that have always been there. Just need a little push and see what offer this version of Tiny Core Linux to us.

picore install

alpha version download links, but we can choose stable releases too.

Installation is as simple as choosing the version that best suits our needs:

  • is the base system without graphical environment but with all the power at our disposal. It takes about 7 seconds to boot. The changes you make will not be saved on every boot, although this behavior can be modified.

  • contains the same as above, but with SSH Server for remote connections and midnight commander. For connection via SSH the user is tc and password piCore.

  • presents a graphical environment with Dock on the bottom bar. Boots in about 25 seconds and it have several utilities to configure the network, mount partitions or install programs among others (I found browsing SDL2 who giving to me many headaches on Raspbian).

PiCore base system. Click to full size.

It starts with a default user named tc with no password and you can't run as root. Comes with a SWAP partition zlib compressed in RAM, although it can be disabled through the boot codes or directly on /mnt/mmcblk0p1/cmdline.txt.

PiCore with graphical environment. Click to full size.

To find applications on the terminal, use the command tce-ab app_name. This command will allow us once you have found our program, several actions such as install or download it.

Terminal. Click to full size.

In conclusion,I liked the first contact with this distro. I hope to test it more thoroughly and if you test it, I would like to know your opinion.

See you soon!

Discovering Picore (Part II)


We continue with interesting aspects of this distribution called Picore that we review in the previous post.

I warn you that it's a distribution that aims to maintain a "fresh" state on every reboot. Basically, the application you are going to use is downloaded and run in RAM memory and dissapear at the next reboot. That's the philosophy, but we can install applications maintain it always available. Let's see a bit how the system works and if it's really worth.

I opted for piCore-5.2-X that has a simple desktop environment but ready for any task. I want to thank bmarkus which is the main package builder and he offer to us support for Raspberry Pi in the forum. Let's start!...

[ Resizing the SD card ]

First thing we'll do is reclaim the entire space of our SD. To do it, follow some simple steps in the Terminal:

sudo fdisk /dev/mmcblk0
Press: p, d, n, p, 2, first cylinder of the Linux partition (in my case, 673), w

You can see the Terminal running these commands in the following screenshot

Resizing the SD card with fdisk. Click to full size

Once we reboot the system, format the partition with:

sudo resize2fs /dev/mmcblk0p2

On this partition we'll have available the /tce directory where you can store documents, videos and other files, and applications that you download through the application manager. Two directories that are not volatile on each reboot are /opt and /home too.

/dev/mmcblk0p2 now has 1.7 GB free. Click to full size

[ What if I plug a flash drive? ]

If you're in X, automatically is mounted the /mnt/sdaX directory if you have the application PCManFM loaded. If not you have the MountTool that you can find in the Dock and mount/unmount any drive.

[ Now I want to try some apps ]

Before you must know the meaning of several concepts that, although at first seem confusing, it is not when you try.


Apps. manager

When installing an application, we can get from various sources. The principal will be the Cloud > Browse option and if you have previously downloaded any app, appear on the option Load App Locally. Packages has the extension .tcz.

Now let's look at the four methods that Picore Apps. manager presents to us:

  • OnBoot (tce-load -wi app_name): The application is loaded into RAM memory and will be ready at the next reboot (this is important). Must be included in the /mnt/mmcblk0p2/tce/onboot.lst file. If it's not included, add it by yourself. Boot times may be long, since that loads everything found in the file onboot.lst into the RAM.

  • OnDemmand (tce-load -wo app_name): Similar to above, but not load any app into RAM memory at startup, although is created shortcut menu if the application has the option to do it.

  • Download + Load (tce-load -wil app_name): Download the app and load it into RAM at the same sesion. This is the recommended option. You have available these apps in the /tce directory always.

  • Download Only (tce-load -w app_name): Just download the application in the /tce dir. If you want to load, run: tce-load -i nombre_app.

Once you have found the application, choose one of the four methods in the bottom left and pressing the "GO" button if you are in X.

Apps, mc, top & dillo3. Click to full size

To load previously downloaded apps, just go to the Apps > Load App Locally option, choose the program and press the Load button. From the Terminal: tce-load-i app_name.

Reviewing the package list, these are some packages that have caught my attention: aircrack-ng, bluefish, compile-essentials, curl, dillo3 (web browser), dropbear (light SSH server), ffmpeg, filezilla, firmware-atheros, firmware-ralinkwifi, firmware-rtlwifi, gnumeric, node.js, ruby 1.9 to 2.1 and go (programming languages), gparted, gpicview, grep, gstreamer, gtk 1-2-3, htop, ImageMagic, viewnitor (image viewer), kismet, lame, lftp (ftp/sftp/fxp/http/bittorrent client), LXDE, moc y cmus(music player), mp4v2, mpg123, nano, ncurses, netsurft, nfs-utils, nmap, ntfs-3g, openbox, pcmanfm, python, git, python-RPi.GPIO, rpi-videocore (raspivid, raspistill,…), wiringpi, mongoose (simple & functional web server, more info here), samba, SDL, SDL2, transmission, wget, wireshark, vnc.

[ Conclusion ]

Although these are the first steps to understand this operating system, it has many possibilities. You can read the pdf manual here. There are many missing packages in the repository and you don't have the possibility to watch videos yet. Hopefully that will come soon.

To fight daily I prefer Raspbian sincerely, but for a specific project like home automation control, a small web server, security camera control or connection through the GPIO port certainly it has much potential.

Now it's your turn.

Raspbian minimal: What's your choice? (Part II)


We continue exploring new distros, new flavors, to boldly go where no operating system has gone before...

Remember I start to write about some minimal Raspbian based distribution on this article. Now it's the turn of two new OS very interestings: pipaOS and PiBang Linux.

pipaOS. A Debian Raspian based distribution for the Raspberry Pi board computer.

  • No specified on its website. Read the notes.

Notes: Inspired by Crunchbang Linux. The author cover three versions: server, openbox and i3. Long time that not being updated. Pibang use SystemD. They have their own repository and a forum to get involve.


This 4 presented distros are for me the best option to get a Raspbian minimal with a base system packages. Like I said, I recommend pipaOS because it's the lighter distro I've tested and fast. I hope you liked these articles.

Do you know any other minimal OS?...

How to build your own OS with Raspbian Net Install


Something that I think is a "must have" on operating systems are modularity. I mean anyone can create one without much knowledge and that you can customize it as you like. On this post we are going to use an unattended installation of Raspbian with armhf and build a new one according to our needs.

Introduction (skip if you wish)

Long ago, what I liked most at the time of Windows 95 was compress the Windows folder with arj, delete useless files and see if I got more noticeable speed on my 486 DX2/100 Mhz. When failed or BSOD appeared, I extracted the folder and start again.

With nLite and other tools, everything was easier with XP, but I spent much time and years of my life in this practice.

When I discovered Linux thanks to a friend (Gentoo), I was fascinated with everything that he could do with Linux and I tested many distributions (Mandrake, Red Hat, Debian, Ubuntu). It was unbelievable all you could customize, but I wasted long time compiling software, drivers and kernels...

Now that I have some years and my time is money, I bought an iMac where everything works, to install an application you just have to drag it to a folder and all hardware works perfectly.

And here I am again with the Raspberry Pi. Returning to my origins and testing ways to have a distro that suits my needs because I think that there are too many packages installed on Raspbian. But it's normal. It is made so that you do not have to fight with anyone or anything.

However, if you're a fighter like me, let's see how to customize a distro Raspbian minimal. Perhaps other methods that would be ideal (like PiLFS, maybe I'll try it someday), but the easiest way I've found is with Raspbian unnatended net installer, so here we go!...

Creating SD image and unattended installation

The version that we start to use will create a base system, in this case with preset for use as a server, but is valid for any other use, installing the latest packages from Raspbian downloaded at the time of filesystem generation.

  • Download the next file:

  • Extract the .zip content on SD card previously formatted with FAT32.

  • Connect it to your Raspberry Pi and the installation begin to partition and install packages.

NOTE: You need to configure your static IP if you don't have DHCP on the router configured. Watch the official documentation at the end of article for details.

The user is root and the password raspbian

Raspbian unnatended net installer

I'd like to highlights some characteristic:

  • Completely unattended, you only need working Internet connection through the Ethernet port

  • DHCP and static ip configuration (DHCP is the default)

  • Always installs the latest version of Raspbian

  • Installation takes well under 15 minutes with fast Internet from power on to sshd running

  • Fits in 512MB SD card

  • Default install includes fake-hwclock and OpenNTPd to save time on shutdown

  • /tmp is mounted as tmpfs to improve speed

  • No clutter included, you only get the bare essential packages

  • Option to install root to USB drive


After the computer restarts, can do a number of customizations:

  • Set new root password: passwd

  • Configure your default locale: dpkg-reconfigure locales

  • Configure your timezone: dpkg-reconfigure tzdata

Install latest kernel and firmware package:

apt-get update && apt-get install linux-image-rpi-rpfv raspberrypi-bootloader-nokernel
&& cp /vmlinuz /boot/kernel.img && reboot

For improved memory management performance: apt-get install raspi-copies-and-fills

Optional: Create a SWAP file with

dd if=/dev/zero of=/swap bs=1M count=512 && mkswap /swap
echo "/swap none swap sw 0 0" > /etc/fstab

These steps will increase the consumption of 11 MB RAM and are not necessary, but recommended.

Remember you can access through SSH.

Add user

  • Now you are God, so the best method is become mortal: adduser pi, or any name you prefer.

  • To view the groups we belong to, run: cut -d: -f1 /etc/group.

  • If you want to add your new user to a group: usermod -aG {groupname} username. Example: usermod -aG audio,sudo,ssh,video pi

  • To view the groups you belong to: id user_name

Install packages

Everyone is free to install the packages you need or think you will need. In my case I usually install the following as pi:

apt-get update && apt-get install mc unzip nano sudo git build-essential alsa-base

To enable the sound module, run after the installation of alsa-base, the next: alsactl init

Back to restore everything

If for some reason you want to redo ALL the steps, run the following:

mv /boot/config-reinstall.txt /boot/config.txt && reboot

When restarts, it will run unattended installer again.

Final Thoughts

We have seen on another posts the use of Raspbian minimal distros and known another alternatives. I definitely think distros like these and better to manage the Pi resources and memory. We have also learned or remembered basic tasks such as managing users and groups. Do not hesitate to try it and if you find problems, you can ask in web project hosted on *Github * or here in the comments.

Now you have a script on PiKISS project to config all the steps without much effort.

Commodore 64 emulator to celebrate Valentine's Day


We can't spend a lot of money in a day like this, but certainly if you call any restaurant in your city, I'm pretty sure you can't take any reservation. So it is best to stay home with your Raspberry Pi and try this emulator I propose to you...

100 Commodore 64 games in 10 minutes!

VICE emulates one of the best selling computer of all time, the Commodore 64. Casually, I have an original one gathering dust and I've never used it (please, don't kill me).

I thank the user welshy from the official forum for this gift. How great you are, man!

I put the links of the binary if you have a partner, but if you are a "forever alone", here goes the source code to keep you busy...

PS: Post dedicated to my two women, Elena and Laura. For the first I gift you this night and to the second the next morning. I promise to play with you to Pac-Man 2 (SNES) or TMNT (MAME).

Reach 200.000 visits!

thank you

10 months were required to reach the first 100K visitors, and have just enough over three to reach 200K unique visitors...

Still here, with more or less regularity in my post. Often depend on the accumulated work, family life or simply looking for some news that has not yet appeared in the media, and it is an increasingly difficult challenge to overcome.

Is there anything that has changed in recent months? On the international scene, a lot of PCBs who continue trying to get a better Pi, some very interesting. But the strong community behind our Raspberry Pi, proudly shows us that it is still the right choice for our projects, emulators, media centers or to get an online server.

Looking back when I reached the first 100K visits, I commented that wanted to expand the other sections, and I think I will do the opposite: Now I will focus exclusively on talk about Raspberry Pi. The reason is simple: It's what interests me today and I think also the people who know my blog. The blog has achieved many visits from places outside Spain. I have more care when writing articles in English and at least for now no one has complained.

I'm not going to entertain a lot: I want to thank to the Google Docs fans, to people writing me emails, comments or retwitt/share my posts. For me it is a real pride that you are my reader, really. Also people who call or write me if I want to work on a project and earn some money. This is always great and now I have three of them.

I hope we keep reading for a long time!

Turnkey Distributed Search Engine Solution on the Pi: YaCyPi


Google was our favorite search engine when Yahoo or AltaVista taught to us what was the advertising. Now Google and his "Don't be Evil" slogan, sell our information and unfortunatelly we have a strong dependence to use it today.

What about get your own search engine with your Pi? I'll teach you a new Kickstarter project with this idea in mind.


"YaCyPi is a turnkey solution for the Raspberry Pi with the goal of turning a common ordinary Raspberry Pi (Model B) into your very own search engine. Using the software YaCy, you no longer need to be bound by Google, Bing, Yahoo, etc for your internet queries."

Like I said, It's a new Kickstarter project who has reached this goal in a short space of time.

It's based in a Puppy Linux OS. It's a decentralized search engine technology based on a peer-to-peer index-sharing network, under GPL license. You can run this OS not only in the Pi: Odroid3 and BeagleBone Black are included.

More info and current project status in the link below.

Link: > YaCyPi - Turnkey Raspberry Pi based Internet Search Engine

Time, time, time


Today I have not found anything interesting to talk about, so I want to comment something you should know: I use to update old post to "modernize" or update its contents. Sometimes changes are simple links that no longer work, I add others to give more information or I extend it...

This usually does not take a long time. Sometimes I think it can help.

Today I have also been reviewing the Google Docs those blogs that have stopped publishing information for 3 months. It's been over 10 who have thrown in the towel and feel bad because they have very interesting articles.

Must add tests with my Pi to post an article or resolve any doubt from someone who write to me.

Anyway, there are many tasks and sometimes I run out of time to find information (that's another story) to the blog and it is increasingly difficult to find.

To all this I call "background work".

I would like you to give me your opinion about this blog. If you like it as is, or do you prefer quality content rather than both "background work" or want to put news even if I take it from other sites. At the end of the day this blog not only is for me.

Thank you.

News this week on the Pi World


Always good to know the most relevant news about our Raspi. This week has been on the cover...

  • Wolfram Alpha present a demo about its new programming language: It will incorporated directly on the Raspberry Pi and give us access to all the information offered by this great engine of knowledge.

  • Tutorial: Using Telegram from Terminal: An article quite carefully worked about this new system messaging clients on the desktop and web.

  • PiTFT, an elegant way to integrate a touch screen with a Raspberry Pi: If you want to have a touch screen for your projects with a resolution of 320x240 pixels and 2.8 inch, on (translated) talk about it and its possibilities along with a case to fit.

Happy weekend!

2 years with the Raspberry Pi: Happy Birthday!


News does not stop repeated in all blogs: Our beloved Raspberry Pi turns 2 years old. From here I want to write my impressions and take a look the plans about their future...

It began as a project to bring programming to the English education system, and has become a set of goals and projects that have upgraded to better development board and why not, personal computer for everyday use.

In the interview published by to one of its creators Eben Upton, says that neither expected so successful. It has not only entered into the classroom, but have created very popular clubs mainly focused on getting this board game throughout the world.

For just $36 we can get one to run some small projects with large-scale capabilities. Not forget to mention we can get a great Media Center or a great entertainment system with games.

The Future of Raspberry Pi

Apart from hardware improvements are still working, we'll achieve software improvements and the most important news is the release of the documentation about 3D graphics drivers for BCM21553 GPU thanks to Broadcom, which would support multiple devices to run Android 4.x. It will cover acceleration based on OpenGL ES 1.1 and 2.0 natively for many more projects that are already supported. If you want to expand the details about this documentation, you can see it in a great article on

Let's not forget a port of a web browser based on Epiphany and Wayland support.

Will we see a Raspberry Pi 2.0 in the horizont? The answer is NO. They think the Pi still have a lot of life and they don't want to leave it behind.

I have many projects for use it and in a year running this blog, I have not bored of it and I have not even thought that I need another having more power like the BeagleBone Black, although I miss that could run Android properly or have a decent web browser, but it will come, I'm sure.

PiMAME 0.8 Beta 1 SD card image available!


In early February I write about the script about PiMAME and we had available a preview of this distribution Raspbian based, to play emulators without any effort. Today we have the image available to make things work out of the box...

Remember that PiMAME is a Raspbian distribution with menu at startup so that we can enjoy with PSX, MAME or Neo Geo emulators, among others.

I have a couple of post waiting for this release and now that I have I can't seen the news anywhere. As said, unless it have some bugs to correct, everything works fine.

I will update this post when I test it. While here it is.


News this week on the Pi World


Short but intense. Sometimes we are not have any other possibility.

TGIF!, but later than usual. I review the panorama for the week in the Pi World...

  • Make: now has a winner:. Participants in a competition they have done recently, has won $500 prize with the development of Gerrit Polder's Slow Scan TeleVision (SSTV) Camera wich send TV signals encoded in FM wave from the Pi to TV. Awesome!

  • OpenELEC releases new Beta 3.95.1: Updated various packages but mostly important is the high version about* XBMC Project Gotham (13.beta1)*. The image can be downloaded here.

  • Customize RetroPie loading screen: I loved to change the look of my Windows 95 with the Microsoft Plus! package. Since then my Windows seemed all but the operating system by Bill Gates. Today I do not usually change more than the wallpaper from time to time, but I still like to do each distribution personalize something "yours." If you use RetroPie, this forum thread can help you change the boot screen. There are some that are adorable. By the way, their script continues to improve and it is capable of running Mega CD games. I ask to you... Did you know that there is a second part of Another World called Heart of the Alien for this console?.

Happy weekend!

OpenMSX 0.11.0 for Raspberry Pi!


Updated 05/Oct/16: New 0.13.0 binary here!!

In this post you can get the latest version of the OpenMSX emulator I've compiled for you and if you are a PRO, how to compile it by yourself...

openMSX 0.11.0 dev version running on the Raspberry Pi from VampierMSX

[ Compiling... ]


In four hours and solving a few dependences, you will get the compiled binaries of this great emulator

Now you have a PiKISS script to do it automatically: Check here

First download the source code. It can be obtained from Sourceforge website here. The date of this version is Nov 8, 2014. If you want to know the changes, visit this link.

Once uncompressed in a directory, you must resolve dependences. With Raspbian for example use the next command:

sudo apt-get install libsdl1.2-dev libsdl-ttf2.0-dev libglew-dev libao-dev libogg-dev libtheora-dev libxml2-dev libvorbis-dev tcl-dev

Arch Linux:

pacman -Sy libpng libxml2 sdl sdlimage sdlttf tcl zlib gcc make python-2

We need to install gcc 4.7:

sudo apt-get install gcc-4.7 g++-4.7
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.7 40 --slave /usr/bin/g++ g++ /usr/bin/g++-4.7

Then you only need to run the following to compile and install:

export CXX=g++-4.7
sudo make install

[ Binaries ]

I created a .deb package that you can install and download from the next url:

Direct Download: openmsx0-11.0armhf.deb

dpkg -i openmsx_0-11.0_armhf.deb

Remember you have to install dependencies: sudo apt-get install libglew1.7 libtheora0 libao4

Run a rom file with: openmsx file.rom

To uninstall: sudo dpkg -r openmsx

It use as bios the C-Bios which is royalty-free, but you can use a bios dumped from an original MSX as I teach you in this post.

Notice: if you want to emulate real MSX systems and not only the free C-BIOS machines, put the system ROMs in one of the following directories: /opt/openMSX/share/systemroms or ~/.openMSX/share/systemroms

If you want openMSX to find MSX software referred to from replays or savestates you get from your friends, copy that MSX software to /opt/openMSX/share/software or ~/.openMSX/share/software

[ Function Keys & OSD Console ]

You can define the Function keys in the settings.xml file. The most relevant are:

  • Menu key: Menu.

  • F9: Rewind to load the tape faster.

  • F11: OSD Console.

In the OSD panel, we can type help to list all the available commands, for example toggle_fps.

[ Optimize ]

Best machine to emulate and with the best compatibility are: Philips NMS 8250 (MSX2, 50 fps), Panasonic FS-A1WSX (MSX2+, 60 fps) o Panasonic FS-A1GT (MSXturboR, 60 fps).

The emulator is not scaled, so If you want play with full screen, change the next lines on the /boot/config.txt file:

framebuffer_width = 800
framebuffer_height = 600

NOTE: The next optimizations are already included in the 0.11.0 version.

To speed up a little, edit the next file: nano ~/.openMSX/share/settings.xml. Add to section the next lines hosted on

SliTaz: New distro for the Raspberry Pi


SliTaz is distributed for Raspberry Pi as a series of files with a size less than 100 MB uncompressed, providing a fast, robust and elegant system who work entirely in memory.

Another distribution to ARM devices.

SliTaz run in RAM when booted with an compressed root file system called an initramfs/initrd. The amazing is that the whole system will be loaded in just 20MB of available RAM.

The list with supported packages is still low, but their functionality to perform server potential is so great. It can even be generated with a proprietary tool and get a fresh raspberry flavor :P

You will need to uncompress the base package and create in your SD three partitions: boot, swap and root . Then run the installer and that's all.

I have not made ​​it to work by a permissions problem, but I hope do it soon and offer to you a deeper analysis.

Open Lighting Project on Raspberry Pi


Today we will learn something about the Open Lighting Architecture

One of the things that give more attention on the Pi is the versatility to suit any hardware project: Control servo motors, lights, automation systems, etc..

Open Lighting Project tries to establish a standardization protocols to control lighting systems via software and open source hardware.

The next awesome video shows what can be achieved with this system...

Raspberry Pi OLA opendmx FT232 sn75176 MovingHead LightScanner

The Open Lighting Architecture (a.k.a. OLA), It is a framework that supports all types of devices and architectures. This project participated in the Google Summer of Code 2012/13. Another interesting aspect is that you have an API for languages like C++ or Python.

In short, buy a hardware that suits your project and the software that we present in the following tutorial from and you can control any lighting system no matter how powerful is.

It's an interesting system mounted on Open Hardware certainly be cheaper of your projects and was previously only available to enterprises.

News this week on the Pi World


Begin April reviewed the panorama of raspberry with new OpenELEC version and commands that you should know to handle yourself with your Linux distribution...

  • OpenELEC launch beta 4.3: Earlier this week woke up with this new version called internally 3.95.3 with improvements in BCM2835 driver, xbmc 13 beta 3 updated and patches to the kernel among others. You can download the image from > OpenELEC-RPi.arm-3.95.3.img.gz (.img)

15 useful commands you should know: RPI is Linux, and as such, move freely through the console is our daily bread. gives us this great article in which we learn to use the feared console for neophytes.

  • Raspberry Pi - Admin Panel: This personal project seems elegant and very well executed. This is a panel for monitoring The Pi via web . You only need to install NodeJS. Link:

I leave you with a video that I liked about the differences between Arduino Uno and Raspberry Pi.

Happy weekend!.

HOWTO: Adding a new emulator to PiMAME menu


PiMAME has become in the preferred distribution with a bunch of emulators to play. The new awesome frontend presented to us in their new beta and the boot animation that can be personalized, even easier we want to love this distribution.

Do you need a new emulator into the supported systems menu?. I will teach you how to do it in the last Beta 8.x...

PiMAME comes loaded with many emulators, but it may be the case where you want to incorporate your own or another that is not in the menu.

[ Prerequisites ]

Let's see we need before anything else. First we are going to install the new emulator. In my case I'm going to choose OpenMSX who I compiled for you recently, but you can install what you want. Write down the path to the executable. For OpenMSX is /opt/openMSX/bin

In the /pimame/roms directory create a new one with the name of your emulator. In our case: mkdir msx. Now you need to put some games inside.

We will download a jpg file from internet with the image that will appears in the menu. I have chosen the following:


Sony had their particular MSX, too

You need to copy it on the directory /home/pi/pimame/pimame-menu/icons/default

[ Modifying the menu ]

The new PiMAME menu is written in Python, so you have to edit the source code but do not fear it, because it is an interpreted programming language and we will not have to compile it again. Simply add the following lines, previously modified with information on the emulator you have installed, to the file /home/pi/pimame/pimame-menu/config.yaml

NOTE: Make backup to this file if something goes wrong: cp /home/pi/pimame/pimame-menu/config.yaml /home/pi/pimame/pimame-menu/config.yaml.bak

- label: Nombre_emulador
    visible: Yes
    icon_file: imagen_emulador.jpg
    roms: /home/pi/pimame/roms/roms_emulador/
    full_path: yes
    command: ruta_emulador

My code is:

- label: openMSX
    visible: Yes
    icon_file: msx.jpg
    roms: /home/pi/pimame/roms/msx/
    full_path: yes
    command: /opt/openMSX/bin/openmsx

Done!. With this steps we have a new option in the PiMAME menu:

rpi module

What the hell is this? I tell you: A RAM module disguised as a Raspberry Pi. LOL

Busy week as you have seen, or not seen in this case as I have not written anything so far from the past Sunday, but I'm happy with everything that is happening in my life, and also happy to show you what happened this week in the Raspberry Pi scene.

If you are a Google Docs fans you've seen many updates throughout the week. It is easier to update and still have their dedicated followers. I appreciate the messages of encouragement and that you share it. Remember the contest to win a book about Raspberry Pi .You have until next week to participate.

  • New product, Raspberry Pi computer module: This module seems a laptop RAM module but is a miniaturized Raspberry Pi for specific projects, containing the BMC2835 processor and 512 Mbyte of RAM. Is designed for those who want to create their own PCB and is the perfect complement to the Compute Module IO Board. More info: > RASPBERRY PI COMPUTE MODULE: NEW PRODUCT!

  • PiMAME to the Crowdfounding: Our friend Shea Silverman recently married and had no idea how much money does a house and of course, now he need a Kickstarter campaign to buy a bunch of pieces, buttons and so on, to test their famous distro. Let us help!. PiMAME Kickstarter.

  • Control applications with the voice with Jasper: Now you can take the control of your Pi talking to it. Two guys from Princeton University have developed a voice control system with a Raspberry Pi. All the info in

Howto make Raspberry Pi a reliable server system!


This week I am a little distracted with personal business, but remember that the contest ending tomorrow and you can win a book about Raspberry Pi. You have the details here.

Today I bring you a link for those who plan to just set up a server on your Raspberry Pi, from the point of view of the SD card and file system optimization.

Guido Stepken is a professional from Berlin and he has been reviewing the importance of a good storage system. In this case the SD card, although we use for almost everything, has a very low access times and is best to get a good quality SD card and use the best file system like this one by Samsung called F2FS.

Do not miss this interesting article if you want to make the most of your card.


Maynard, Wayland-based desktop for Raspberry Pi

Maynard thanks to Marco Barisione

Be honest, LXDE is a lightweight desktop but not have hardware acceleration makes opening any application an odyssey and take longer than we wish. Nearly a year ago we know the development of Wayland but everything is in a Alpha state and we don't know when come to us.

Maynard will be a X replacement with hardware acceleration and moves quite well as you can see in the video. It doesn't support applications that are not developed for it yet, but you can try it if you dare running the following commands:

Banana Pi

This is NOT a Raspberry Pi

This week we have as usual new and good projects to keep an eye. Want to know more?

  • Mosquitto message system: I had read about this project, but not sure what it was. It is a system to transport messages with the MQTT protocol. Devices can "talk" with a variety architecture. Imagine a sensor sending messages to a mobile or an Arduino. |
  • Banana Pi, Raspberry Pi clone with steroids: Pow! Right in the kisser. This is a new competitor you have to look twice to avoid confusion with the Pi. Bring a 1GHz Allwinner A20 dual-core ARM Cortex-A7 con 1 GB de RAM for about $55. Details in You can buy it on their website or although careful you do not go to brew a Raspberry Pi.

  • piCore 5.3alpha2: This distro advancing with leaps and bounds and brings kernel 3.14.1, Raspberry Pi firmware (14 April, 2014), BusyBox patches applied, improved tce-load. |

  • Raspberry Pi on tutplus: I wanted to finish recommending the website with good tutorials about Raspberry Pi.

Nothing more people. Until next time!

Rpi Simple Monitor (Android App)

rpi simple monitor

From the Twitter account @raspipc I know a new application to monitor the state of our Raspberry Pi through Android. Their name: RPI-Simple Monitor...

The application displays information about CPU, RAM or temperature through an elegant interface.

You need to install a server program on the Pi.

I encourage everyone to try and I'm pretty sure the developer would appreciate feedback through their Twitter @laux_es or in the Google Play.

Survive to the Back Week with a Raspberry Pi: IRC clients

pi hacker

Since last April 28 is celebrating an event called The Black Week (La Semana Negra in spanish). Objective: Survive one week only with the Shell with no desktop environment. Do you accept the challenge?.

xkcd comic

Courtesy of

I found it interesting proposal and I'm actually excited, since many people are moving into the Linux world thanks to the Pi. You don't be afraid black background with letters any more!.

You should avoid write startx voluntarily, but keep calm, because you are not alone. I'll show you some applications to notice that you do not need a mouse to write an email, browse the internet or post to Twitter.

Today we start to get into the IRC and meet people like you who are participating in this initiative. So you can share and learn about new applications that will serve you throughout this week.

My proposal for a good IRC client will be weechat.

To install: sudo apt-get install weechat

Once we execute it with weechat, we will connect to the freenode network typing /connect Now we can enter various chat rooms, but which we are interested to get into #semananegra on spanish irc channel, so type: /join #semananegra

Another usefull IRC commands are:

  • Change nick name: /nick new_nick

  • Send a private message: /msg nick message

  • Show users in the channel: /names

  • Leave chat room: /part roomname customexit_message

  • Exit from the app: /quit

Another keys:

  • TAB: Autocomplete nicks or texts.

  • Alt+Cursor left/right: You move through the different buffers you have open (To learn more about the buffers, read the link I put at the end of the article).

With this you can manage a little longer, but there are still many things to learn, but that depends on you ;)

If you don't like weechat, you can install another one like irssi or you can use a XMPP client called profanity.

Just for today. You can comment your impressions if you wish.

See you tomorrow!

Survive to the Back Week with a Raspberry Pi: Read emails


We continue with the challenge of being 7 days without X. Is it painful for any of you?. Today we'll install an email client.

As you can see, these articles are being focused on the daily use than any normal user can give to a computer from a non-professional perspective.

[ VOW ]

I put my heart next to yours, to do ours one wider and secure. I pledge to you, terminal. I'm yours for a week. When I feel weak, I will be strong and will not tear the X when ascii videos overwhelm me, I will be strong and see the entire series of Star Wars in ASCII, I'll be strong when the eyes do not bear it, I'll be your shadow when you do not know any command, I will smile, I will cry.

Until the GUI do us part.


Cone. Press to full size.

The mail client I will use is called cone. You can install it from the repositories: sudo apt-get install cone

I will use a Gmail account through IMAP, which is the most common, but you can set it to any other account. Just be aware that to access via pop/imap to your Gmail account should have this option enabled from your account (read here).

To set up a new email account, just follow these steps: Press M (MAIN MENU) > N (NEW ACCOUNT) > I (IMAP). In the next screenshot you can see my configuration (with password invented to mislead the number of characters, hehe).

Configuring cone with Imap. Press to full size.

Done, it is so easy to read your mail from console!. Now I leave you to search how the hell you can send a mail, because I have not yet achieved, LOL.


  • Star Wars: telnet

  • BOFH (Bastard Operator From Hell): telnet 666

Transform you Raspberry Pi into a video game console with INDIEGO-OS (Indiegogo)


Another crowdfunding project that we can see and based on the premise of using AEROS operating system already talked as platform launching an SteamOS alternative like store. Let's see what offers to us...

Always is good for the community to support interesting projects to use with the Pi. Today I find this campaign to create a friendly environment with the AROS core and can be used on PC, Mac, RPI, ODROID or others. The UI is based on the Amiga MediaCenter and you can run games from Amiga , Windows (via Wine even ARM), Linux or AROS all via emulation. According you can read, it has the compatibility of Linux, because it is based on Debian, with the speed of AROS.

For the "free for all" AEROS release, which is something that concerns us all, they need 3,000 euros.

It is said that you will also have access through this system to Steam, Desura and other stores. For the Raspberry Pi, is planned to be also a gateway to Streaming from PC (with Limelight) and also serve as a platform of entertainment to watch multimedia files (videos, photos, music). Other things to pay attention is that run Windows 8 ARM apps with wine, though not perfect.

I leave you with the video of the campaign.

XLink Kai for Raspberry Pi

xlink kai

Xlink Kai is a tunneling software for Windows that allows you to create a direct connection between two or more identical game consoles through internet.Originally created for Microsoft original Xbox, it now supports Xbox 360, Nintendo Gamecube,Sony Playstation 2 and Playstation Portable.

It works fooling game consoles, in other words making them believe they are in the same network the other console is, to achieve this it requires you to connect your console to the same network router or switch where your PC is connected to internet, then let the software web interface detect your console.

To install, you need to download, uncompress & run the next package:

tar xzvf kaiEngine-7.4.28-RC1-linux-arm-headless-raspberry-pi.tar.gz
cd kaiEngine-7.4.28-raspberry-pi

PiKISS for Raspberry Pi & ODROID-C1: A bunch of scripts with menu to make your life easier


NOTE: If you want to know the history changes, visit this link

This is my most ambitious project for the Raspberry Pi.

Install an application on Linux is not complex. Sometimes just type sudo apt-get install and get the application installed with all its dependencies. But... What if we need to install more than one such as a web server?, Is it not in the official repositories?, What if you want to get rid off input commands?. Please, an easy way to set my WIFI network!.

Don't despair. PiKISS has come to help you...

[ Introducing PiKISS ]

PiKISS Main menu

PiKISS (Pi Keeping It Simple, Stupid!) are Bash scripts for Raspbian (for now) which has a menu that will allow you to install some applications or configure files automatically as easy as possible.

PiKISS (Pi Keeping It Simple, Stupid!) are shell Scripts (Bash) for Raspberry Pi 1 & 2 (Raspbian and derivates) and for ODROID-C1 (Ubuntu) soon, which has a menu that will allow you to install some applications or configure files automatically as easy as possible.

The idea is offer facilities to manage your operating system, selecting an option in a menu and answer [Yes/No]. If you need check dependencies, install an app, modify a script at boot, add a line to a file or download other, PiKISS will do it for you.

Forget about type and edit any command or file anymore!

What some users have said about PiKISS:

  • "It could have happened to me!"

  • "What a silly! (I'll install it when I go home)"

  • "Now I don't need to fight with the terminal? Shut up and take my money!." - Easy, it's free.

NOTE: ** 100% Free of viruses and Trojans. Not available in stores. The author of **PiKISS is not responsible if you get bored with your Raspberry Pi because everything is too easy. Online until I wish or Internet is destroyed.

piKiss --help

[ Installation ]

You can get it from GitHub:

git clone

Now install emulators is very easy with PiKISS!

[ Update ]

If you want the latest version, just enter into the directory with cd PiKISS and type:

git pull

NOTE: If you use another flavor from Raspbian, maybe you need to execute the next command: git config --global http.sslVerify false

[ HELP ME! ]

PiKISS grow up according to users requests ( or I'll append scripts that I consider necessary, but I call to the community to share, improve and help to add new scripts to the existing one. If the project grow, is up to you.

Don't you know how to configure your static IP?. Easy now!

NOTE: If you want to know the scripts included on this project, please visit this link.


This project has involved many hours thinking, searching, refactoring and testing code. I accept donations due the effort to make new scripts. Donations are not required or expected. Any amount that you feel is appropriate would be appreciated. Simply click on the Donate button below. Thank you! :)

Syncthing: Open source P2P file sync



We all know bittorrent Sync and I talked about this method to have the files on hand.

Syncthing becomes the solution to these open source systems such as centralized storage like Dropbox...

With Syncthing you have a way to store your data and have it available whenever you want and wherever you wan, using the P2P protocol.

Some of its features are:

  • synchronize as many folders as you need with different people

  • responsive web GUI;

  • cross-platform: Syncthing works on Linux, Mac OS X, Windows, FreeBSD and Solaris. There's also an unofficial Android port;

  • Syncthing doesn't require advanced configuration and it should work out of the box, both over LAN and over the Internet;

  • secure & private: the data is only stored on your computers, without using a central server; all communication is secured using TLS;

  • every node is identified by a strong cryptographic certificate and only nodes you have explicitly allowed can connect to your cluster;

  • open source app, open protocol.

Curious that even though looking at my blog, I can't find no post has mentioned Sonic Pi, and soon we will see the version 2.0 of this free program that allows development to teach programming through music...

With Sonic Pi you'll be able to teach some programming concept through a simple programming environment, ideal for starting from the earliest age.

An example:

# flight of the bumblebee RasPi.TV style (or lack thereof)

# first some rythms
speed = 0.45  #set overall speed
breve = 8 * speed
semibreve = 4 * speed
minim = 2 * speed
crotchet = 1 * speed
quaver = 0.5 * speed
semi = 0.25 * speed
demi = 0.125 * speed
hemi = 0.0625 * speed

Still do not know what new features will have this new version, but in the article on The Mag Pi last month you can read a full article.

News this week on the Pi World

Raspbery Pi

It seems like yesterday when was on sale the Pi and have already been sold 3 million units worldwide.

I will continue here, updating the most complete Google Docs for the Pi and increasing PiKISS scripts, which remains in the gap.

Let's review the international scene!...

See the summary appeared on the blog on the RPI that I found interesting:

  • Size: 85 x 54 mm

  • Number of expansion cards: tens

  • Noise level: 0dB

  • Weight: 45g

  • Display: 1080P / HDMI

  • Power Consumption: 2.5 W

  • Maximum altitude reached by a Raspberry Pi: 40 km

  • Maximum number of Raspberry Pi in a cluster: 64

  • Use: Servidor Web/Mail, Media Center, emulators and games, video streaming, DIY projects, etc...


  • Pipplware 2.0 FINAL, Portuguese origin distro with many features: Having gathered in a single distribution XBMC, XFCE, Chromium or RetroPie is not an easy task, but this distribution succeeds. Ideal for beginners in the world of the Pi. It has a very good menu system and was updated last month. Maybe I dedicate an article next week |

  • MagPi released (June): Do not miss the interesting Magazine which is the number 24. I found it very interesting, in special an article about WIFI Sniffing |

See you!

The World Cup with Raspberry Pi or Ubuntu

Brasil 2014

SCRIPT UPDATED: 18/Jun/2014 7:37 GMT +1

NOTE: Now you can enjoy more channels with the new script that I have prepared. Click on this new post: PiKISS: Two new scripts join to the family

I do not like football, but with the excuse to watch the match we meet friends for lunch/drunk.

Want to see it too? Take your Raspberry Pi or a computer with Ubuntu because I have prepared a script to enjoy the show...

NOTE: Sorry, only spanish audio, but if you want it in english, tell me in the comments...

Just boot your Ubuntu or Raspbian and execute the following:

curl |bash

For Ubuntu you need to install mplayer and with Raspbian you will need omxplayer (HDMI output). Both should have them already installed in their respective operating systems.

If the signal goes, I will try to update the file.

PiKISS: Two new scripts join to the family

tvstream PiKISS

These days I'm kinda busy with the generation of two scripts that have seemed to me very interesting to the PiKISS project: Stream TV channel and DLNA/UPnP server...

[ Streaming Spanish TV Player ]

Today, the only way we have to watch streaming channels is installing on XBMC (OpenELEC, Raspbmc,...) a plugin to view it. With the World Cup, I've parsed a xml file where come all channels created by PiKoMule here. It's a fairly updated today file, and have been used to create a menu (which has given me more of a headache).

Notice that 80% of channels do not work today. I hope PiKoMule update as soon as they "fall". However the script is here for you to test and comment.

Channels that have tested now and work are: GolTV, GOL TV Option 2, EuroSport HD, HD FightBox, La 1, Antena 3 Neox, Energy, The Sixth Clan (Pat the Postman), 24H, 13tv, RTPA.

For future updates, I hope to incorporate international channels if I get another xml file.

[ Rygel: DLNA/UPnP Server ]

Rygel is just one of the many Media Server in the World. Its function is to share multimedia files by streaming audio, video or images via the server where you install it. I opted for this one because of its simplicity and consuming memory. Its main features:

  • Browse and play media stored on a PC via a TV or PS3, even if the original content is in a format that the TV or PS3 cannot play.

  • Easily search and play media using a phone, TV, or PC.

  • Redirect sound output to DLNA speakers.

I've done tests with an iPhone 4/iPad Mini with the AcePlayer App, and a 40" Samsung TV with very satisfactory results. You can use any application with DLNA/UPnP support.

TVPlayer is already in PiKISS and Rygel will be tomorrow.

Happy Wednesday!

The most interesting thing for me this week has not been curiously visiting channels where I search for information, so this post is more like a whole week working on my little blog for all relevant news, but surely you will like...

Tor or how to hide your tracks on the Internet

Tor Pi

By now we all know that each search direction we visit or comment that we make on the internet, like it or not, will be registered with our IP.

Tor becomes a project to not reveal our identity (IP) passing through other PCs and so leave our hidden secret to all kinds of requests corporations, governmental or not.

I admit that sometimes I have done internet searches undesirable and I'm ashamed. But surely you do this practice too. YES, I searched Youtube video of Rebecca Black or use Google to know how to shave without cutting.

But the NSA will not know this information because a user has prepared this script to convert Moebius Linux distribution in a whole onion router. It would be interesting to do the same for Raspbian, because I'm not a fan of the distribution that has used its author. It remains to incorporate into PiKISS.

New Amiga emulator port on the way: uae4all2


Currently we have 2 Amiga emulators for the Pi: UAE4All and UAE4Armiga4Pi than I've spoken. Both are based on uae4all1, which has no support for HD files.

uae4all2 comes with several interesting improvements, including support for HDF files, AGA...

There remains much work to run the emulator decently as says the user is developing the port, but if it's running on various platforms such as Pandora or GP32X or other with a capacity similar to the Raspberry Pi processing, I can say with total security that this emu goes to the right direction.

I think it is not difficult to compile. As it has done will upload the binary and see if it works as well as on other consoles and devices.

I leave you with a video of the emulator running on a Nexus 10.

Raspbian Net Install+PiKISS = Perfect OS combination


This is not really a post, it's more a recommendation.

Yesterday I just got to try again Raspbian NetInstall UA, which is a Raspbian minimal distribution with minimal packages without much...

I tried on it PiKISS and to my surprise almost all the scripts works except some of it with missing packages.

I have found with the most optimized Raspbian OS existing. That's why I added a new script to the family to set some settings in this cropped version of Raspbian. You can find it in the Config section of PiKISS.

PiKISS RaspbNetIns

New script to config Raspbian UA Net Install

The result has been a considerable improvement in emulators. For example MAME4ALL runs at optimum speed without sound problems I always had in Raspbian with some roms (TMNT2).


Laura testing the distro. She is happy with the result.

I advise change. Your impressions in the comments.

Updating your MiniDLNA to version 1.1.3 (binaries inside!)


MiniDLNA is a DLNA/UPnP-AV to see your media content in other devices (SmartTV, tablet, smartphones). I think this is the first solution that comes to mind every time we need to use this service.

I bring you the latest version that came out earlier this month...

The version on Raspbian repositories is a bit obsolete (1.0.24) and the people in the forums have some trouble when compiling it.

So you just have to download the .deb package and copy the configuration file to the folder /etc. To install it and run, you know:

sudo dpkg -i minidlna_1.1.3-1_armhf.deb
sudo minidlnad

However, I added a script that will save you a lot of work on the PiKISS project which it will download the source code to compile the latest version available or install this version 1.1.3.

Just remember: to update PiKISS, you will have to enter the directory where you have, and type: git pull

News this week on the Pi World

Raspbery Pi

This week has been quite active on the blog and on Friday I stay on top, so the section is full of news today. The most anticipated: the sale of the Raspberry Pi modular version for large and small projects. But that's not all...

I wanted to remember that this week PiKISS has received some updates and added some new scripts: checklastmodimg, minidlna, Epiphany Web Browser, crispy-doom, Quake 2, MAME4ALL, Gameboy Advance & PCEngine.

  • PiFox, tribute to Star Fox: Earlier this week we saw proof of concept created by the Imperial College London. An independent game with 5800 lines of code with a Bare Metal system for ARM devices that you can visit on GitHub. As a curiosity, they've used a Raspberry Pi emulator called PiEmu with the source code available too. If you are left wanting more, here you can find a video of a Tetris multiplayer programed with about 4000 code lines in pure assembly code | > PiFox

  • Build Space Invaders with Python: In only 300 lines you can create this arcade classic if you like. It is a good start for those who want to learn programming or how to develop a video game | > Create Space Invaders on Raspberry Pi (part one) (part two)


Official distributions updated and a few more
  • NOOBS is updated and with it, all official distributions for Raspberry Pi: Great news for those who likes change their operating system often. This week we have renew with almost all distributions from the official website, including NOOBS | > Downloads
  • Compute Module Development Kit on the sale: Created to develop embedded projects or applications, this new Raspberry Pi simplifies the design process through a modular system to provide the necessary power to your ideas. Now you can buy at stores like element14 for about 158€ (£126.68).

uae4all2: Binaries available!

uae4all2 menu

As I said recently, soon we are going to have a new Amiga emulator on scene.

A user already has ventured to compile the new emulator and we have available binaries at last. Shall we try?

To give work, unzip the file at the end of the post and be sure to install the necessary dependencies:

sudo apt-get install -y libsdl1.2debian libsdl-image1.2 libsdl-ttf2.0-0 libguichan-0.8.1-1 libguichan-sdl-0.8.1-1

The emulator runs with ./amiga. It is advisable to move around the menu with the arrow keys on the keyboard for now.

You need to get ROMs and copy it in the kickstarts dir. I remember what emulates each:

  • kick13.rom = Amiga A500

  • kick20.rom = Amiga A500+/A600

  • kick31.rom = CD32

Problems about this uae4all2 version:

  • No change DriveSpeed 1x.

  • Custom Config does not work yet.

Environmental control (GUI):

  • "Esc" resets / loads a disk

  • "Ctrl" back in the game

  • "Arrow keys / tab / enter" menu navigation

In Game:

  • "Ctrl" returns to the menu

  • "Alt" switch input (joystick / mouse / stylus?)

  • "Home / end / pg up / PgDown" for fire buttons, etc..

Of course, you have ready the script in the PiKISS project, including kickstart files (ROMs) and a game called...

News this week on the Pi World



It seems that the escene moves a lot in the world of emulation. This week we had the arrival of a new version of emulationstation, but also other news I will discuss below...

  • HummingBoard-i2 available for $45: SolidRun has released a new competitor for the Raspberry Pi, exactly the same size but with some improvements and available at various prices. It is best to watch the video below and judge for yourself. |


  • RetroPie updated to 2.1: I have kept an article comparing PiPlay Vs RetroPie that I hope someday to finish, and while they appear quite frequently new versions about this both OS dedicated to emulation. petrockblock bring the facelift of EmulationStation and now use the SDL2 libraries (with which I am always fought), which has been completely rewritten and with a few improvements |

  • Spreadsheet with Twitter hashtags: I've adapted the code from for a sheet showing all the hashtag #Raspberry_pi & #raspberrypi from *Twitter*. Now you do not need an account on this social network to be informed every minute about your favorite plate. | Google Spreadsheet > Twitter Archiver cloud service for Raspberry Pi

I usually use to save my files (sorry, Dropbox sucks), but I've never used this kind of storage services with the Pi. Wants to backup all my photos, and looking for some services I found, with which we'll have 15 GB of free storage available and has a referrals system to increase this size. Let's see how to configure it in our beloved Pi...

If you stop to think, on a device like the Raspberry Pi make backups is something important by several factors. I reinstall the operating system every week and sometimes I forgot to make copies of some files. For addressing me today, I need to upload 10 GB with photos and videos, so the Pi will help me a lot in this task that may take quite.

[ Installation ]

First you need to sign up on If you do so from this link, you gain 5GB with extra storage.

Then download, unzip and access to the program:

tar xzvf Copy* copy/armv6h/
cd copy/armv6h/

You have two apps: CopyCmd & CopyConsole. The first allows you to certain actions such as download a file or also get the public link you want to share. The second is the one that allows you to synchronize a local folder with the one stored in the cloud. To view a list of tasks you can perform, run these files without arguments.

[ Some basic commands ]

Let's see some fictional examples to learn better how to manage with the commands. We start with CopyCmd:

Create photo folder in the cloud:

./CopyCmd Cloud -password='mypass' mkdir /photos

Copy files from your Raspberry Pi directory to If you want to copy to the root directory, would be /:

./CopyCmd Cloud -password='mypass' put origin.jpg /photo

Copy directory with all its files from a remote server to the PI:

./CopyCmd Cloud -password='mypass' put -r /home/pi/photos/ /photos

List files in the cloud

./CopyCmd Cloud -password='mypass' ls

Download files to your Raspberry Pi:

./CopyCmd Cloud -password='mypass' get photo.jpg photo.jpg

NOTE: We repeat the name of the file as you can see in the above example, since it means: local_file_path remote_file_path.

The most interesting about CopyConsole is the function of keeping synchronized two directories as usual in all these services. an example:

./CopyConsole -daemon -password='mypass' -root=/home/pi/photos

So, everything we have in /home/pi/photos keep synchronized on both sides, local and remote.

Nothing more. Of course, there are clients for all devices and operating systems, so access to all your files from anywhere is assured.


Download: Copy.tgz

Download entire website via FTP with a single line command


Getting out a little from the standard pattern, I tell you that yesterday I needed to back up the blog, hosted on 1and1. The trouble is that the only way to do this is by FTP. So as I make copies every Friday, I show how you can download your blog with lftp or wget with a single line without flinching. Want to see it?...

It's not the first time I talk with some of my clients or friends and they forgot to make backups of the blog. They think it will work as long as the disaster by either hosting or hacking exploiting vulnerability arrives: Everyone gets nervous and can not remember when was the last time they made a backup.

[ LFTP ]

LFTP is a ftp/http client that support ftp, ftps, http, https, hftp protocols. It's a common package in any distribution and if you have not installed, you simply type sudo apt-get install lftp

To make a remote backup, simply type the following:

lftp -e 'mirror / /path/' -u user,password website

Example: lftp -e 'mirror / /home/john/my_backup/' -u johnftp,rpi43v3r\!

NOTE: The password, if you use characters like !, must be preceded by a backslash \

[ Wget ]

Not a day that does not use this command on my daily chores. Here to download this blog:

wget -q -P /url/path/ -r ftp://user:passwd@website

Example: wget -b -P /home/john/ -r ftp://johnftp:rpi43v3r!


  • Argument -b causes the files to be copied in the background and generate a log, although we could have used -q for not show the exit.

  • wget is a little faster than lftp.

Benchmark on Raspberry Pi


We have seen many users doing overlock to know their PIs limit and not turn it into an ornament for your desktop.

Benchmarks allow us to know the computing power that has a CPU/GPU in general, and today I'll show you a command to check yours...

Credits goes to Dinesh Auti, which has developed a post to show how to use it.

Just run the next command called bc (binary calculator), which calculated the values of Pi with arbitrary number of decimals.

time echo 'scale=1000;4*a(1)' | bc -l

Curiously, the author of the article with an raspberry Pi without overlock has given the following results:

  • 1000 decimal: 4 sec 37 milliseconds

  • 2000 decimal: 24 sec 29 milliseconds

I remind you that you can know more technical details with the nbench tool, which is available for installation via PiKISS.

sshfs: Mount remote directories via SSH protocol


In my day to day I use Ubuntu installed on iMac (the teasing that I can receive, I know). When I remotely access my Raspberry Pi or other equipment with Linux, I usually use Filezilla, but I discovered a cool way to access my directories through the main operating system through sshfs...

This command will allow us to mount our file system on a remote directory on another computer. To do so simply install it first and create the folder where it was mounted:

sudo apt-get install -y sshfs
mkdir rpi

Load the module with: modprobe fuse

Mount inside our operating system the remote directory with:

sshfs user@server:dir_remote dir_local

An Example: sshfs pi@ /home/ubuntu/rpi

With this we'll have the pi directory on another computer, no matter if it is on the local network or in the cloud. If we want to unmount it before turning the Pi off: fusermount -u /dir_local (Following the example: fusermount -u /home/ubuntu/rpi).

Amiga UAE4ALL 0.3 rc4 emulator for Raspberry Pi

Amiga 500

Amiga 500

User Chips bring to us a new version of the Amiga emulator. Details below ...

Only two dependences:

sudo apt-get install -y libsdl1.2-dev libsdl-mixer1.2-dev

This is the best Amiga emulator I've never seen.

New in V0.4:

  • Now joystick can be used to go back from emulation mode to menu. If you have a joystick with more than 4 buttons, any button except the four first one will trigger the main menu.

  • Now Amiga Vsync is synchronized with Raspberry Pi one. It enables perfectly smooth emulation. Since emulated Amiga is Pal, ensure to set Raspberry Pi to 50Hz display mode otherwise graphics jitter will occurs.

  • Since Vsync management is completely rewritten, Auto frame skip is less effective than in previous version. However it looks like enough for Raspberry Pi (especially with cyclone core).

  • Improved double buffering: CPU is no more blocked on Vsync waiting.

  • Menu can be driven using Joystick.

As always, you can download with the rom and a game from the PiKISS project.

Banana split Pi

This week has contacted with me Lemaker, the company who make the Banana Pi which we talk at the time, to offer one of their plates. So you will see content about it on this blog soon.

Anyway, we'll see some news this week have been posted on the Net about the Pi...

  • Wyliodrin: Interface for lacy developers. Best is to see the video that heads this paragraph: Programming from the browser with a similar language like Scratch that will result in lines of code in Python |

  • Remotely deploy projects to the Raspberry Pi using NetBeans IDE: IDR Solution teach us how they have developed their application for the Pi using Java through this development environment |

  • Raspberry vs Banana: hardware duel. With the incipient arrival of Banana Pi, I was looking and I found this post that compares the two plates. Maybe it's not very honest if they are Lemaker partners, but there it is. Do you have one? |

What is it?. This weekend you will know...

Begins in September and with it new goals, new hopes and fresh news about the browser epiphany we could already installed via PiKISS...

I have to comment that this week I got the Banana Pi in my hands, but it seems that it have a problem and the HDMI show something wrong. I hope to resolve it soon in the forum or from the technical service.

Moreover, Lemaker guys have told me if I would be interested in writing a book about the Banana Pi, but I'll be somewhat busy. I would not mind if any of you could help me to write the book and distribute income generating. If you think you can do it, I accept candidates. Please send me an e-mail.

Retro-remake: Conquestador for Raspberry Pi

3 luces

Dedicated to the memory of Javier Cano, TOPO Soft developer

Las Tres Luces de Glaurung (a.k.a. Conquestador) was a legendary 8-bit computer game created by TOPO Soft in the called Golden Era of spanish software, when Spain became the second largest 8 bit computer entertainment software producer in Europe, only behind the United Kingdom.

Today you will be able to play the remake made by masoftware guys and ported to the Raspberry Pi by myself.



It was probably one of the first MSX titles I had. It is one of those games that are desperate difficult at first until you become the character control. The good thing is that you can save games.

The object of the game is to find the Three Lights and leave the castle. These three jewels, like the rest of usable objects are stored in chests scattered around the map. But these boxes can also contain harmful things, so that we will be very careful. Probably at least one or two gems will be in the lower regions, where the danger is greater, but this is not certain. In any case, once we must turn to the right side of the castle where the exit door, taking care to carry, also is the key that opens this door, in which case we will have completed the adventure.

To play, you need to unzip the file you'll find at the end of this post and install Allegro libraries:

    sudo apt-get install -y liballegro4*

Now start the graphic server with startx, open a Terminal and cd the Glaurung directory. To play just run: ./glaurung

News this week on the Pi World


As you know I recently got a Banana Pi for various projects I have in mind. Unfortunately after much test I think it's broken. So I'm waiting for another, so you'll have to wait a little those who want to see more news on this board. This week we talk about translators, xming and video surveillance systems with motionPie...

  • Universal Translator: Based on Python and translation services online, this translator can get you more than a pinch, but do not expect miracles |

  • CCTV Security System with Raspberry Pi: We have seen some video surveillance guides on this blog and the Google Docs have a whole list. This tutorial is added as it is very cool, especially the case you can buy at this store called It use a distribution based on Buildroot and Motion called motionPie |

New release of Raspbian (& NOOBS too)


A few days ago The RPi Foundation upload a new version of the official OS Raspbian and the OS installer NOOBS. If you want to know what's new on this release, you can read the full post.

For those who are looking forward to change repos from Wheezy to Jessie, we will have to wait a little longer.

  • Epiphany browser

  • Switch to Java 8 from Java 7

  • New firmware

  • Minecraft Pi pre-installed

  • Sonic Pi upgraded to 2.0

If you want to upgrade your actual Raspbian distro:

    sudo apt-get update && sudo apt-get dist-upgrade -y


Synergy: Control multiple computers with a single keyboard and mouse (Youtube)


A year ago I talked about a software that allowed you to share keyboard and mouse with multiple computers. I tried using it but it did not work. Today I have made a video tutorial to see how it works and how comfortable it is...

Synergy on Ubuntu - Raspberry Pi

I have been tested with Ubuntu, but it works on Mac or Windows.

As you can see, the steps are simple:

  • Install the program on server (computer with keyboard and mouse) and client.

  • Configure the server with the GUI.

  • Run on the Pi: synergyc --daemon ip_server

I've noticed it only works with the desktop environment, so you have to type in the console: startx

For the lazy, I created for PiKISS a script that install, enable you to choose the server and run it on startup.

NOTE: The author now charge for the program but is still free. The nighty builds are available for all platforms. I'll leave the link below, although I installed it on Ubuntu and Raspberry Pi from the repository:

Lessbian: Jessie Raspbian server


Unfortunate name for a distro... What do you think?

We are all waiting to jump from Wheezy to Jessie on Raspbian to obtain the latest packages of our applications for both server and personal use.

Today I found this ready server operating system wich you can use for any task...

Lessbian is a stripped down Jessie Rasbian containing minimal number of useful packages to create a headless WiFi server.

This is a specialized distro intended for experienced developers and security experts who want a working base system to configure according to their needs.

Latest versions of hostapd, dnsmasq, kismet, aircrack-ng, tor, reaver, nmap etc. are bundled

We have three versions to download:

  • lessbian-2014.09.11 Jessie with systemd and root mounted ro (root password raspberry), has separate XFS partition for /var

  • lessbian-2014.09.16 Jessie without systemd, and has /var/spool mounted in extended XFS partition (root password is lessbian). Wireless power management is off by default at kernel level.

  • lessbian-tiny-2014.09.18: absolute minimal image with kernel 3.16 and wifi support

safe Pi

Today I have been tempted and bought an iPhone 6. After three years with the version 4 I needed a renewal, mostly because my wife will inherit it and I do not like Android operating system. Hopefully someday iOS could be installed in other Smartphones. Moreover, in this section we'll see how to open a safe "by the face", Perforce (another Dropbox killer) and learn what the hell it Shellshock vulnerability.

  • Security camera with face recognition: A good weekend project to have a safe that is opened recognizing your face. Code available on GitHub if you want to modify it for other purposes. |

  • Shellshock, learn to avoid it: In short, it is a vulnerability in the Shell Bash that takes advantage of global variables. For a user like you and me it's not a big deal, but for servers and big business can endanger a lot of valuable information. If you want to know if your computer is vulnerable, run the following:

env x='() { :;}; echo vulnerable' bash -c "echo this is a test"

If you get an error, your computer is safe.

To fix it:

apt-get update && apt-get upgrade bash

Pi Entertainment System (PES)


PES is a graphical front end for a variety of games console emulators that has been written in Python by Neil Munday which is intended for use on the Raspberry Pi.

Although Java is still the programming language most widely used in spite of me and Python is rising as the years go because of their community and their simplicity, are lenguages I would not use in my projects, and less one that should be a fast Front-End to load ROMs emulators.

Still deserves a chance. The image weighs a little already. Tell me what you think in the comments.

ScoutBot: Penetration testers for Raspberry Pi (IMG)


ScoutBot is a must have application for penetration testers who are looking for an easy and inconspicuous way of gathering info on a target's network.

Built for the Raspberry Pi, this powerful script automates complex footprinting and reconnaissance tasks. While you enjoy a cup of coffee sitting next to that open Ethernet port ScoutBot could be scanning the network or sniffing the traffic, all without the need for a keyboard or monitor.

Here are some of the features:

  • Scans the target network for open ports

  • Identifies Windows environments

  • Identifies dynamic routing protocols

  • Identifies devices by scanning with SNMP

  • Identifies DHCP servers and their advertised scopes

  • Checks egress filtering

  • Identifies the network's outside IP address

  • Performs a WHOIS to identify ISP

  • Performs a traceroute to the outside

  • Accepts static IP addresses

  • Accepts DHCP

  • Pre-configure for a completely automated attack

  • Works on any Raspberry Pi, no setup necessary

  • Free

Basically, you pre-configure the scan and then just plug the Raspberry Pi into the target network. This tool comes as a preloaded IMG which is ready to use.

NotanOS: Operating System in the cloud


NotanOS is an operating system on Alpha state that has caught my attention and reminded me to EyeOS.

Imagine install an app based on Node.JS and make available in any web browser a front-end with a entire graphic desktop...

Notanos on the Raspberry Pi

As mentioned, the requirements are minimal: any operating system (not Raspbian necessarily), node.JS and userserv. Then run the following and access from a web browser to https://ip-raspberrypi:

tar -xzf notanos.tar.gz
ln -sr notanos ~/Notanos

It don't have a demo where you can "play", but the idea is very close to EyeOS with a demo ready for you in this link.

Pi Vessel: new minicomputer for the whole family

PiVessel 01

Past Friday I mentioned this minicomputer that is searching founders from Kickstarter. A member from the staff contacted with me to expand the information in this blog, so click on continue if you want to know more about it and its great features...

A team of engineers from MSDGroup developed a new super-affordable minicomputer based on the Raspberry Pi platform with Linux operating system. The computer is equipped with all the components necessary for work and play right after the purchase. The Pi Vessel is assembled with a Raspberry Pi board (in two modifications: B and B+), 8 GB memory card, built-in power supply, as well as a Linux operating system. All this is fitted in a stylish aluminum case that will enhance any interior design.

The minicomputer can be purchased in two versions: Fully assembled and ready for use or as a package of components for assembly by the user.

The uniqueness of the Pi Vessel minicomputer lies in its combination of multifunctionality, affordable price and ultra-strong, stylish case.

[ Multifunctionality ]

PiVessel 03

The Pi Vessel is a minicomputer for the whole family that lets you work with text, presentations and spreadsheets, as well as play games, videos and audio recordings.The computer can also be used as part of a home theater, storing and playing films in full HD quality. In addition, the Pi Vessel can work as a control and information processing unit in a Smart Home system. In the office, the Pi Vessel can be used for streaming presentations via a projector, as a useful and inexpensive alternative to bulky PCs or expensive laptops.

[ Affordable price ]

The original idea behind the Pi Vessel was to create a computer that would provide its users with sufficient processing capabilities for work and play, but costing a fraction of other similar devices.The price of the Pi Vessel is $139. The mini PC is one of the most affordable computers on the global market.

[ Ultra-strong and stylish case ]

PiVessel 04

When developing the case for the Pi Vessel, the goal was to create a stylish and durable case that would effectively be a lifetime purchase. The result is a compact, stylish and ultra-strong aluminum case that can easily withstand not just a hammer blow, but also a weight of a car.

PiVessel 02

The Pi Vessel is assembled in Germany, and will officially be launched in January 2015 at the CES international show in Las Vegas. However, the backing campaign for the Pi Vessel will start on with delivery scheduled for December 2014.


New Banana Pro from Lemaker


Banana Pro

As we know, Raspberry Pi is not the only development board based on the principles of promoting science, technology, arts and math (STEAM). Plate that more direct competition makes to the Pi is Banana Pi, with best hardware, and now has been renovated with new and exciting features...

In early 2014 it was presented a new board with best hardware than Raspberry Pi, undisputed queen with 3.8 million units sold to date.

Banana Pro is an upgrade of its predecessor with more possibilities: SoC Allwinner A20 with Dual-core ARM Cortex-A7 (ARMv7-A) 1GHz Mali400 MP2 GPU and 1GB DDR3 SDRAM.

Now use microSD and SATA 2.0, WiFi 802.11 b/g/n (rtl8189es) and composite audio/video joined in one Jack. We now have 40 pins to connect with the outside world.

It seems that the new plates fever development has just begun and the necessary renewal of existing augur a promising future in this world to develop interesting projects at very low cost.

Install Latest Transmission on Raspberry Pi


Great tutorial I want to show you today to install the latest version of the best torrent client for the Pi: Transmission.


PopcornTime on a RaspberryPi with PiTV!


PiTV streams movies and TV shows from torrents like PopcornTime do...

To install:

sudo sh

Note that running this script on your system "hijack" Raspbian to make it yours. That is, many applications are installed and when you restart, boot to X with Google Chrome in background. Undo the changes is complex. Also it is a very early alpha version, but I've tried it and *it works**.

When PiTV is ready it will display a Raspberry logo on an orange background.


You can then access the remote control via browsing to the local IP address of your Pi as you can see in the capture above.

PiTV's remote will display all series and movies, which it can find on The MovieDB.

To play an episode or movie, select it and wait some seconds for PiTV to load the torrents.

Git Server on Raspberry Pi in 5 seconds


Many of my readers are developers. Sometimes we have needed to work with projects with code that does not want to share with the world. GitHub is the hub to save all the changes in our projects with a great version control system, but unless you want to checkout, all repositories that you think it will be open to the public.

If you want to store the changes you're making in your code with Git system on Raspberry Pi privately, read on...

The steps are complex and requires that you follow each of them without committing a fault, otherwise you might destroy your Raspberry Pi, ...naah!, just kidding. I thought it was something more complex because I am not an expert on Git. Just only use a few commands daily.

What I have done is create you a simple script to execute this in your favorite distro and I've uploaded to PiKISS

I leave the script below just in case you want to take a look:

OpenWRT and Latch on a Raspberry Pi


Security is one of the topics that I'm passionate about and I do not spend all the time I want, but I'm follow the best blogs about it and today Chema from Un Informático en el lado del Mal (A Computer guy on the side of Evil) has given us this excellent tutorial avout setting Latch with OpenWRT on Raspberry Pi. If you don't know what I'm talking about and want to know more, read on...

OpenWRT is basically an operating system specifically designed to provide network functionality to a computer or router that can act as a firewall, AP WiFi,sniffer, etc. Yes, you can install it on a TP-Link o Asus router or choose embedded devices such our lovely Raspberry Pi.

Latch is an online service to add a layer of security to any project: bank accounts, servers Web/ftp servers, developments,... All controlled by a panel to protect that what we protect: Our privacy. Recommended this read.

  • Slimming a Raspberry Pi: Now comes a time of abundant food and should lose a few Kg. Your Pi also wants to lose a few grams and some height for those projects that need it. Adafruit help us to eliminate parts of your Raspberry Pi but beware, it's not easy. | > Diet Raspberry Pi

  • FruityWifi: It's a tool to audit wireless networks for Debian systems. Very useful and easy to use with a cool Web interface that reaches version 2.0. It's worth a try for all the modules that brings incorporated. | FruityWifi


Bartop arcade with two players: I love gaming. Just name them and I go back in time, transported to those video arcades where we shared those afternoons with a few coins and freak people. If you can't get one because the size, I recommend a Bartop that fits anywhere. | > 2-Player-Bartop-Arcade-Machine-Powered-by-Pi

Raspberry Pi A+


20% cheaper, 24% shorter and 42% thinner!

Eben Upton spoke about it a few months ago and it's already the new revision of the Model A, with changes almost all expected...

Raspberry Pi Model A+ Launch

Obviously this is a B+ model cut in benefits to give your projects a system less power consumption. Here are its features, although you imagine:

  • 700MHz Broadcom BCM2835 CPU

  • 256MB RAM

  • 40pin extended GPIO

  • Better sound

  • 1 x USB 2 ports

  • 4 pole Stereo output and Composite video port

  • Full size HDMI

  • CSI camera port

  • DSI display port (Raspberry Pi touch screen display)

  • 4 mounting holes

  • Micro SD port

  • Micro USB power connector

  • The board has a smaller footprint but is fully HAT compatible

  • Size: 56mm x 65 mm

  • Weight: 23 gr.

  • No Ethernet port

In my humble opinion, they are still fail putting only 256MB RAM. They should have taken advantage and launch the plate with 512MB, I'm sure sales would reach the top. What do you think about it?

rPlay at the end of November for the Banana Pi


If I were you I would buying a Banana Pi.

Today browsing the forums on I see that the community is moving quite. Although lack of good support in the graphics hardware acceleration, we can see interesting projects soon.

For now, we will have a rPLAY version for Banana Pi (paid) with support for: AirPlay, AirPlay mirroring, and Miracast Chromecast. Video of his performance below...

PC as a Display for Banana Pi

The price of this software is not yet confirmed but will be around $5-10. Pretty good if they promise what we can see. The big problem of Raspberry Pi is their CPU and can't run Google Chrome decently, so I don't think it will continue its development beyond the beta we have.

The software will run on any version of Android 4.3+.

It will be available on the website and probably I'll get one license.

More info:

Lakka: Retro-gaming distro based on OpenELEC


Interesting this distro found in the Banana Pi forums and although provides experimental support, for Raspberry Pi is complete and quite stable.

But what have this distro that don't offer others like RetroPie or PiPlay?. Jump to the post and see!...

Lakka menu on Raspberry Pi

As mentioned, the author has taken the OpenELEC core, get rid of Media Center features and created an elegant menu like PS3 as you can see in the video above.

It's based on RetroArch and we can play emulators like NES, SNES, Sega Genesis or PSX among others, but the developer promises a fast system with the following features:

  • Based on RetroArch and OpenELEC

  • 85 Mb Distro with read-only access

  • Update system not based on package, but on the whole file system and kernel.

  • Open source

  • Friendly menu

  • Rewind, hotplug hoypad, video streaming, screenshot, pause games, save states,...

The team is currently debugging the front-end and not just be available for the Pi but will support Banana Pi, Cubix-i or Cubietruck among others.

You can try stable version, but also provided daily versions for different devices on the link leave at the end of the post.

[ Test Log]

  • I have tested a development version you can download here.

  • Overclock to High but It will work fine without modidy this parameter in the config.txt

  • On first boot, resizing SD to its maximum capacity.

  • It takes about 13 seconds to boot.

  • The menu run smoothly.

  • Comes with SSH enabled by default (root@root).

  • Added to config.txt, hdmi_drive = 2 to get audio through the HDMI port.

  • To copy ROMS it uses Samba, so you'll have to use another computer on the network. I have copied all without subdirectories and the menu show us sorted by the extension (.nes roms appears below the Nintendo menu, etc...)

  • I connected a wired XBox-360 control pad and It recognized in just 2 seconds.

  • Tested and working perfectly: FBA (Cadillac & Dinnosaurs), SNES (Kirby Superstar with craps sounds but this game is heavyweights. Super Mario Bros work perfectly), Genesis (Sonic 3), NES (Super Mario Bros 3).

Network Speed: raspberries Vs bananas

Lan Test

Many of us want to use the Raspberry Pi to build a NAS, DLNA server, Samba shared folder or any project that makes heavy use of the network. Sometimes we forget about the limited Raspberry Pi capacity of bandwidth that has the Ethernet port and we forget alternatives like the Banana Pi.

Frank Mankel is a user of a Google Plus community on BPi and shows us how quickly he test it using iperf. Let's see the results of a file transfer over the network...

The file used has 3.1GB from a shared folder with NFS to a IntelNUC with the following results:

1. BananaPI 1 to my IntelNUC DC3217IYE
2. BananaPI 2 to my IntelNUC DC3217IYE

The transfer was completed in 1:03, which are approximately 50 MB/s. Remember that the speed with the Pi is about 6-8 MB/s. What do you think?


Top Operating Systems with img updated recently (Nov, 2014)


It seems like yesterday and it's been six months since this compilation of operating systems. I think it's time to review the distros that have updated their images or have been forgotten...

Operating systems have recently updated their image are:

Distros which have not been updated in the past six months:

  • PiCore (May)

  • SqueezePlug (May)

  • SliTaz (Mar)

  • MinePeon (Mar)

  • Moebius (Jun 2013)

[ Conclusion ]

In the past has gone distros like Inferno that promised to be a very profitable experiment. Many are also committed pipaOS, but not updated since July and I think the author does not have a lot of courage to release it to the top (I've tried to contact with him and not responding). Leaves the list SqueezePlug that we can replace it with piCorePlayer. SliTaz still generate packages. I wanted to add Moebius because he enjoyed some popularity, but its author is tired of Debian distros, but promises a revolutionary new version. We look.

FreeBSD continues to update their OS. Media Centers also have regular monthly updates. I have joined the list updated with Diet PI that I want to keep an eye. We has Sonic-Pi, OpenSUSE and Slackware among others. Firefox OS added but still not more than a proof of concept.

Overall distros for Raspberry Pi are healthy and most stay alive... Live long and prosper!.

News this week on the Pi World


Does anyone remember BeOS and its true multitasking power?

Hello people! One more week, here we are with some news not so prominent in the weekly panorama as usual, but surely you are interested in more than one. Today I bring to you news about Haiku, clusters...

Raspberry Pi B+ Cluster (Super Computer) Part 1
  • The MagPi num. 28 (Nov): New and interesting articles with OpenCV, Arduberry, VoIP, Git, FUZE BASIC and much more. |

  • LinkIt ONE VS Edison VS Raspberry Pi VS Beaglebone Black: Development plates everywhere!. Here we have a comparison of four of them, and according to our needs, make better use one from another. Round one... fight! |

  • Raspberry Pi B+ Cluster (Part 1): In this first part of a series of three videos, Rasim Murtovic teaches the components needed to assemble a cluster server with four Pis. On the second install and configure Raspbian and the third will show you how to program for advantage in processing power thanks to the cluster. In the video that heads this article we can see a case to mount the cluster simple but pretty cool.


Haiku OS
  • What awaits us in Haiku Beta?: I used to be a BeOS user at the dawn of time. The news of a ARM port opens new possibilities for our machines. I have never seen a faster operating system like BeOS and more efficient for computers where we installed sheepishly Windows 95 or we fought with the Linux kernel to run X. Haiku accepted the legacy of this dead operating system. | Translated to english: > What awaits us in Haiku Beta? - Related:

OpenMSX 0.11.0. Choose a flavor: Banana or Raspberry.


This weekend I have been exchanging emails with the staff of openMSX emulator and have compiled the latest version of which I consider the best MSX emulator at the moment. Do you want to run on the Raspberry Pi at 50 fps?, Want to try the first port of this emulator for Banana Pi?. Enters without knocking!...

Athletic Land

Athletic Land: Best MSX game EVER!

If you want to see the changelog go to this announcement on

I know you're dying to try it, so if you have a Raspberry Pi, I updated the post where you can get it.

For Banana Pi users, I used Bananian as distro to compile and the link with instructions to make it work are the same as in the post I mentioned for Raspberry Pi users. You can find the download link at the end of this post. Remember to install the dependencies: apt-get install libglew1.7 libtheora0 libao4.

The emulator is surprisingly well on both platforms, although I notice that on BPi goes better.

I want to thank the members of openMSX Team and specially to Patrick van Arkel and Manual Bilderbeek for the help received in the IRC channel (freenode) #openmsx. Some of them already have a Raspberry Pi, so you will enjoy a compiled version by themselves of this great emulator soon.

Demo XBMC-Gamebox: Airplay mirroring for Raspberry Pi (Youtube)

XBMC Gamebox

Last Friday I wrote about a new competitor for rPLAY. Well, I have tested and I want to show you in the video below a demo...

First say that it's an image with 1.3 GB based on Raspbmc. I've tested with a *Raspberry Pi Model B.

With the first boot, the image resize the partition to take up all the space on your SD card.

Once the system has rebooted, you will see XBMC version 13.2 (Oct, 2014). Now you must to choose the language, which has not worked for me but it is not important.

In the Programs section we find Raspbmc settings and the last doesn't works.

We will activate Airplay mirroring because that's what we want.

XBMC Gamebox for Raspberry Pi

The system moves fluid as you can see in the video. I tried several games and some are not going at all well, taking cuts that make it difficult to play.

The video streaming has lag from iPhone 6 and iPad Mini Retina, perhaps due to the buffer is too small. If you play from the Video reel, no problems.

Doesn't works when you want to power off the Raspberry Pi from the power menu, so you have to unplug it even without being the Raspberry off.

The conclusion I reach is that if you want to use Airplay mirroring technology, this solution just works if you do not want to spend the money on an AppleTV. About Raspbmc, is not as stable as we would like but it's OK.

What if I want to run Gamebox from Raspbian to take advantages from Airplay Mirroring protocol?. You can. Follow the instructions in the next post in the forum.

SSH connections,... and forget about passwords!

SSH hodor

If you don't understand it, this blog is not for you

This guide is essential to our daily with SSH connections, but sometimes we become lazy (I'm the first).

I explain VERY EASILY how to generate keys you need so you don't have to write the damn password in each SSH connection.

Let's create the public/private keys and copy the first on the remote computer. Wrote the following from the computer where we are going to connect (in my case, a Mac):

cd .ssh
ssh-keygen -b 1024 -t rsa -f id_rsa -P ""
ssh pi@ < ~/.ssh/ 'mkdir -p .ssh && cat >> .ssh/authorized_keys'

OSX Terminal showing all the process. Click to enlarge

With the last command, we copy from our Linux/OSX the public key to the remote device. In this example, (my Raspberry Pi).


It was not so hard, right?. Why have you don't this before?.

If you want to type less, create an alias in your Linux/OSX: nano ~/.bash_profile

Example: alias sshrpi='ssh pi@'

And reload the shell with: source ~/.bash_profile

Now, every time you type sshrpi, will access from your computer to the Pi with no password.

Reflections about ODROID-C1: Another Raspberry Pi Killer?

Odroid C1

I don't comment usually anything regarding Raspberry PI direct competitors, but this has especially caught my attention due their price: $35. Want to know why I bought one?...

One of those videos that we love (OpenGL ES and the rabbit from Blender included)

The news comes from Amlogic S805 released the SDK for Android and buildroot for Linux with support for GPU and VPU (Video Processing Unit). The good thing is that ODROID has a good community and care about their product.

Its features are:

  • Amlogic ARMCortex-A5(ARMv7) 1.5Ghz quad core CPUs

  • Mali-450 MP2 GPU (OpenGL ES 2.0/1.1 for Linux and Android, no OpenCL)

  • VPU for hardware video decoder

  • Power Supply - 5V/2A DC input (2.5/0.8mm barrel). Typical power consumption: 0.5A @ 5V, up to 2A @ 5V with several USB peripherals.

  • 1Gbyte DDR3 SDRAM

  • Gigabit Ethernet

  • SPI, I2C, UART, ADC & GPIO with 40 pin

  • eMMC4.5 HS200 Flash Storage slot / UHS-1 SDR50 MicroSD Card slot

  • USB 2.0 Host x 4, USB OTG x 1

  • IR port

  • Ubuntu 14.04 & Android KitKat 4.4

Odroid-C1 architecture. Click to enlarge.

[ First impression ]

Not fair to compare it with the Raspberry Pi. It's seems a widespread effort to end the reign of the PI. I equate more to the Cubietruck with respect to performance and features. Banana Pi has good things and every day come out new distros and awesome projects from the community, but fails to support the GPU and although you can already test their abilities to play a 1080p video smoothly, it is not something you get out of the box.

It is also true that you start ordering and finally, among shipping and accessories, you have to pay around 54 Euros ($67), but is not bad price for what you get.

I see they have removed the analog jacks for audio/video and has no SATA port, although there is adapters for both technologies.

Odroid C1

Odroid Magazine Dec 2014

[ So What can I do with the Odroid-C1? ]

As you have watched, the connectors to "speak" with the real world are like the Pi, so you have the same possibilities except the disparity in some GPIO port pins. About the compatibility of accessories (Pi-Camera for example), I have not read anything about it, but now has on sale 9" screens and LCD 16x2.

Video playback through Android or Ubuntu reach 1080p due to the hardware decompression H.264/VC1/MPEG4/MPEG2 supports (No need to buy separate license such as the Raspberry Pi) . It is also expected to be compatible with the new format H.265 soon.

To web browser as I have seen in the video that accompanies the article, it behaves with Chromium but we have to test it and avoid drawing wrong conclusions.

For games, a new world of possibilities opens to have the perfect combo CPU/RAM/GPU. In the forums I have seen for ODROID in general that you can run games smoothly as Doom 3, PSP or Nintendo 64 emulators (Sorry, Raspbians), and... Wow!, finally a decent karaoke game to bother the cats in your neighborhood.

If you prefer Android, you have at your disposal a 4.4.2 rooted version for development and you can install the Google Play easily.

[ Final recommendations ]

Perhaps we are becoming very exigent, not because we are satisfied with having a decent desktop and some applications running. We want to see how to reach the best from our mini computers and every time, companies released new boards to the market with better performance because manufacturers know that.

It is too soon (it's in diapers) to have a community or interesting projects. We have to hold their hand and teach to take their first steps.

My recommendation is that if you have a Raspberry Pi and what you like is "tinkering", continues as you are and passes all these new "Killer-PI" boards, although it is true that something stagnant has been with respect to hardware.

If you want Ubuntu or Android with XBMC that just works with all kinds of applications, games or surf the web connected from the TV in your living room, put a blindfold and buy the ODROID-C1 this Christmas (I ALREADY have one).

SD Images to play Game Boy Color, Atari or MSX in a few seconds on Raspberry Pi


Occasionally Internet surprises us unintentionally. A French user with the nick Dr Floyd has created a SD customized for a single emulator images. You wont have to wait long, usually begin in seconds...

They are images that can download through Dropbox. Once decompressed takes about 4GB.

It's Arch Linux prepared specifically for a Pi based console called OctopusPi which was promoted by Kickstarter. Comes with Kernel 3.10.38-1. we can access through SSH (root@root) but games can be copied from the /boot/games directory which has FAT32 (1.5GB free).

Work with the Raspberry Pi Model A and B (problems with detecting joystick with model B+).

Emulators available are:

  • Game Boy Color

  • Atari 400/800/800XL/1200XL

  • MSX/MSX2

Berryboot on Banana Pi


Berryboot is a small distribution to install operating systems designed primarily for Raspberry Pi *. It has been ported to *Banana Pi to make it easier to install multiple distros and not die trying...

The first thing to do is to "burn" the image from this link. Then you can simply unzip and "burn" a SD as you would do with any other distro.

[ Installing your own images ]

Berryboot gives you the ability to insert a flash drive with an .img file and install an operating system that is not in their official repositories. This will generate a new entry in the menu and you can access through it. This is done by clicking on Install from USB stick. If you want a specific memory GPU/CPU shared setting, you must specify it changing the extension .img with .img128, .img192, .img224 or .img240

[ Conclusion ]

Berryboot provides a simple way to install distributions uncomplicated and from a very friendly interface. From Gentoo to Bananian through ArchLinux, Lubuntu or Raspbian. Recommended especially the initiates who want to start testing operating systems without stopping until you find one with which you are most comfortable.

HOWTO play emulators on OpenELEC for the raspberry Pi!


...Once upon a time a user called mezzo asked himself: "Why there is no retroarch addon for the raspberry pi?". So without thinking twice decided to compile the Library so he can play their favorite emulators within their favorute Media Center. And best of all, they shared their knowledge with the whole kingdom and with every house. The villagers could play games and watch movies from a leisure center...

Time ago we saw a first attempt and was only a matter of time before someone would improve the system to use emulators on this distro. I have always advocated for its stability and speed against their adversaries. Now bring us the opportunity to finish watching a movie and playing Hellfire from the Genesis Megadrive (my favorite game).

Supported platforms:

  • NES (fceu)

  • MAME (imame4all)

  • Master System/Genesis (picodrive)

  • Atari (stella)

  • SuperNES (pocketsnes)

  • Others (beta test)

We'll use a SSH conection to our OpenELEC distribution. SSH must be enabled. You can check it on SYSTEM > OpenELEC > Services. The user is root and password openelec.

You have two methods to install. Choose one:

Log into SSH and type:

unzip -d /
killall -9 kodi.bin

[ Method 2: The hard way ]

We need to install the Addon and run some commands in the terminal. My tests have been in the latest version of OpenELEC Kodi, which at the time of writing this article is the version 5.0.

We need also activate the option Show hidden files and folders inside Settings > Appearance > File List.

Execute the following in the terminal:

cd /storage/.kodi/addons/
wget && unzip emula* && rm emula*.zip
wget && unzip repo*.zip && rm repo*.zip
chmod +x /storage/.kodi/addons/*
ln -s /storage/.kodi/userdata/addon_data/* /storage/emulators
mkdir -p /storage/emulators/roms
mkdir -p /storage/emulators/advancedlauncher
# The next copy agame to test inside the rom folder (It's a Homebrew and free of use)
cd /storage/emulators/roms/ && wget && unzip && rm

Addon Advanced Launcher

Advanced Launcher & RetroArch Addons

Come back to OpenELEC and choose in the main menu Programs > Add-ons > Get more... > Advanced Launcher and press the Install button.

Select Advanced Launcher > Default with the right mouse button and choose Add New Launcher as you can see in the capture above, and follow the next steps:

Add New Launcher. Press to zoom.

Create New Launcher. Press to zoom.

1) Create New Launcher > Files launcher: When asked the application you want to launch, follow the following path: Root filesystem/storage/.kodi/addons/

Script Path. Press to zoom.

2) Select files path: We indicate the path of the ROMS: Home folder/emulators/roms/.

3) Now the ROMs extension, for Genesis Megadrive is bin.

ROMs extension. Press to zoom.

4) Application arguments we type: picodrive "%rom%" (or the name of the emulator you want to launch to the file extension. You can see list of supported platforms on the top of the post).

Emulator's name. Press to zoom.

5) Launcher title, I typed Megadrive.

Title. Press to zoom.

6) The platform, choose Sega Genesis from the list.

7) (OPTIONAL) I put fanart and thubnails inside /storage/emulators/advancedlauncher.You should then copy .jpg images inside that folder and add them manually pressing right mouse button on each game.

Repeat these steps for each emulator you want to have.

[ Add ROMs ]

Now we add ROMS clicking on each emulator, right mouse button and select Add Items.

Add Items. Press to zoom.

From now you can play your favorite emulators with hardware acceleration at 60 fps!.

Advanced Launcher with preconfigured emulators. Press to zoom.

[ And now what? ]

To copy the ROMS, we can activate SAMBA protocol and copy from our Desktop computer.

When playing, press F1 to enter the options menu of the emulator, and to select an option, press the key X, to return to the previous menu, Z. Press ESC to exit the game.

You can add more emulators. Go to project lakkatv where you will find binaries, although I have not tried this method commented on the forum, where you can also found Amstrad, Amiga or ScummVM binaries.

You'll be looking forward to playing with Joystick. When you're in the game, plug your pad or joystick and press F1 option and select settings > input > Bind all. You can import your RetroPie configuration and overwrite retroarch.cfg file in the following path: /.kodi/userdata/addon_data/

Here's the final result in a video (sorry for quality, was in a hurry and did not look at the colors on screen):

News this week on the Pi World


Here we are again. This week I have been doing backups of my main computer (sometimes feel that something bad will happen to the hard drive) and other've been testing and correcting the tutorial about RetroArch with OpenELEC, which for me has been the holy grail due I'm a casual player and I use the Pi to watch TV Shows mainly.

Let's see what other things have happened as always, in the weekly summary... Let's Go!

Incidentally, my ODROID C1 is lost in a plane in Korea and still waiting, so no tutorials until come to my home... sniff!

Mis apuntes de... responsive

misa responsive

Better late than never!

Well, after two years, it was time to do the blog responsive or adaptive to different screen sizes, so it will be more confortable for blog visitors navigate it with your tablet or mobile.

It's something that was pending for a long and planned to do a complete change regarding Back and Front-End, but better go step by step and change things slowly (I remember to you that this blog is programmed from scratch, no WordPress or similar CMS). For the Front-End I chose on purecss, but since I'm not an expert in design I decided to use Bootstrap due its simplicity and the help you can find on the internet about this cool framework.

However, I will continue making changes. If you notice something weird, let me know please.

You can post a comment if you like the change.

Thank You!

New RetroPie V2.4.1 released



Long ago we had no news from Petrockblock and this time presents a new version in beta state of the distro for retro-players like me. This time we have a stripped down version of Raspbian (from 1.2 GB to 610 MB) which has eliminated much of the preinstalled software. Let's see some new features...

  • Minor bug fixes

  • Updated RetroPie-Setup Script

  • Update of all components, e.g., RetroArch supports ZIP files natively now

  • Dispmanx can be activated or deactivated for each emulator individually now

  • The screen mode is configurable for each emulator individually now

  • Added Atari Lynx emulator

  • Added Darkplaces Quake (experimental)

  • Added Minecraft-Pi (experimental)

  • Added OpenMSX (experimental)

  • Enhanced integration of ScummVM

  • Stripped down number of installed system packages to a minimum

  • Reorganization of the binaries

[ Comments about this version ]

The first is that the Raspbian version is more optimized for games. Very fast startup and the detection of the XBOX360 Control Pad has done with no problem.

We see few options on the menu:

  • PORTS: Doom, Duke Nukem and Quaque 3 (all shareware, but work without having to get the .wad)

  • Macintosh: It has not worked for me, you may need the ROM or BIOS to work.

  • IBM: DosBox (I would have preferred rpix86). To exit, type EXIT and press ENTER.

  • Apple II: black screen and you need to restart RetroPie.

  • ScummVM (see 1.7.0, 3 January, 2015): Perfect.

roms folder with all the supported systems. Click to enlarge.

Remember that for other emulators, we need to add through SAMBA some ROMs. I tried several and all work perfectly and all the emulators recognized the joypad. To exit of each emulator, you must press the key combination SELECT+START.

What I liked is the resolution changes in each emulator to fit your screen perfectly.

Overall it is progressing rapidly and I think will become in the favorite system of many gamers.

News this week on the Pi World

Odroid Box

Here my ODROID-C1!

The weeks I write little news means I have some tutorial or much work at hand. This time it's the latter, that to be Freelance is not bad. However, do not neglect the section on Friday and I encourage you to comment about today's news. Here we go!

I just received today Friday my ODROID-C1. Has been delayed quite as I mentioned once before, but now I can spare some time to this fantastic board that has started stronger than others.


Review + Youtube: Android v. 1.1 (4.4.2) on ODROID-C1

Odroid-C1 with Android

I've never trust on use Android in this kind of boards due to my constant failures to make it works and do it efficiently. Today we can see in this article if it's worth having a ODROID-C1 with Android running multiple applications, games and emulators. I advise that if you have a Raspberry Pi, better stop reading...


The first thing I should say is I'm testing the Android version 1.1 belonging to Kit Kat 4.4.2. The installation I've done on a 8 GB UHS-I SD card from Sandisk I bought at the same hardkernel store. The image takes up 219 MB only. Everything I had read about Android with an SD was that I neither tried, It's very slow due to constant input/output access that makes the operating system and it was preferable the eMMC... Don’t you believe their dirty lies!. The operating system will run VERY smooth and perfect as you would do on any tablet. I'm sure with the eMMC the experience is flawless, but with an SD is enough, I assure you.

Once inserted the SD card and when boot, the system will resize the partitions available including one vFAT to act as SD card and where we can copy all we need through our PC.

Another positive aspect is that with an 8 GB card we won't run out of space, because the operating system itself will take care of installing applications on another partition if the home is filled. I made the test with resolutions 1280x800 and 1920x1080.

[ Featured Apps ]

I've installed some apps to test. Click to enlarge

I highlight the following installed apps:

  • ODROID Utility: The most important of this tool will be set the screen resolution if it does not fit to your screen.

  • DicePlayer: Player unpretentious but plays almost all kinds of multimedia files without problems (with 4K the system hang).

[ Recommended settings ]

  • Google Play: Not installed by default I guess because Copyright, but nothing easier than download it from this link and run through the file browser. Installing applications is very fast.

  • SuperSU: The OS comes rooted, but need to install this application (or similar) from Google Play to grant permissions to programs seeking access to certain files from the file system. One is Kodi. Without applications like SuperSU, Kodi can't access hardware decoding, nor the video player, so this step is strictly necessary.

[ Testing,... ]


AnTuTu Benchmark reach a score of 14196
  • Benchmark: Running AnTuTu v 5.6, ODROID-C1 I get 14196 points. If you want to compare...


Score of some tablets in the market

  • Video Player: Perfect. Tested with the default player called DicePlayer and Kodi. In fact, it is the best way I've found in ALL boards and operating systems I've ever tried to play videos without dropping frames. I'd tested 4K videos and doesn't work. Banana & Raspberry Pi are losing the war in this section.

  • Games: The limitation I found is in 3D games but not for performance, but because they are developed for use with touch screens and mouse does not work, so we can't press a button to start playing for example. Maybe there is a way, but I’ve not found a solution yet.

Mupen64+ with full speed. Click to enlarge
  • Emulators: RetroArch: Does not work the Nintendo 64 emulator, others I've tried like SNES, GENESIS or MAME runs flawlessly | PPSSPP: Well, except games that demand high graphics in 3D like God of War, currently unplayable. Kindom Hearts is a 3D game also, however it moves and looks smooth. | Spectaculator (ZX Spectrum): Nothing remarkable obviously runs perfect. | Mupen64 + (Nintendo 64): Mario 64 is nearly perfect, both in sound and fps. Maybe a few glitch in some shadows and textures, but hardly noticeable.

PPSSPP and the game Kindom Hearts. Click to enlarge
  • Control Pad: In my case I tried the XBOX 360 wired with the emulators and it works out of the box.

  • Web Browser: I tried the default one and Chrome. The navigation is fluid, not bad scroll across the page, no slowdowns. Mobile Youtube via the browser loses quality, best from the application. No, it does not work Flash but at this point, Who needs it?.

  • Youtube: I installed Youtube due it's a "must have" when my friends come to my house and of course it works as it should. In addition, very fast loading videos.

  • Karaoke: I have not tried to connect a USB microphone, but installing any application from Google Play you can play any .kar files. It seems incredible that something so simple can not work fine with the Raspberry Pi.

  • USB Devices: ODROID-C1 does not come with built-in Bluetooth. I have inserted a USB BT adapter and it has not worked, but not expected. A flash drive in FAT32 has been recognized.

[ Conclusion ]

I can say that Android behaves as it should and can work even operating system. It's a shame the problem with 3D games that only support touch screens, but is comprensible.

In short I conclude by saying that I'm very happy with the combo ODROID C-1 + Android. Not disappoint anyone and connected to the TV in your living room ensures you can use it as a center of entertainment.

If someone wants to try some additional application, just tell me in the comments.

Here you have the video. You can watch how run some applications mentioned in the post.


News this week on the Pi World


First, let me apologize for the fall he suffered on Wednesday due web hosting problems. It took about 8 hours to be solved.

I wanted to remind you that have collected on the right side bar, Google Docs about boards that I acquired and surely will be of particular interest for you.

This week we talk about ghosts, comparisons and VoIP.

By the way, I want to thank you again for the great reception that still has the tutorial about Retro Arch in OpenELEC and comments. Doubts in the post, I will try to resolve gradually.

Burning images to the SD card on OSX


I wanted to prepare this script, as I am constantly testing distros on the Raspberry Pi and derivatives. The solutions I have found on Internet from other users do not satisfy me or fail, so here my solution. Warning, to use it first must follow some tips ...

First of all, comment that this script is made for OSX (soon also works to any distribution of Linux) can burn any .img image into a SD card. The recommendations have to follow are:

  • DO NOT INSERT any USB or HD DEVICE when you use the script.

  • If you have inserted one or more pendrives/HD, will show YOU a list of connected devices and you have to specify which of them you want to use. By default, the device where the image will be copied is /dev/disk1.

  • Also applies to burn USB images not only SD useful to burn other desktop operating systems like Ubuntu, Arch, Debian,...

Remember to give execute permission when you download the script: chmod a+x

To run the script, you need to pass the image path as a parameter:

sudo ./ image_path

Updated distros for Raspberry Pi 2 and those to coming soon


It's appearing the revisions of operating systems to accommodate the new SoC on the Pi2. Let's see those already updated and those to come in the following article.

Raspberry Pi 2 With Kodi (xbmc) Openelec 5.0.1

Updated distros:

4 cores

  • Raspbian y NOOBS: It was hoped that the official release is already adapted to change. What I liked most is the boot start with the 4 raspberries symbolizing the 4 cores of the new processor.

  • Debbian Jessie: One thing I need is to change from Wheezy to Jessie on Debian based distros to get the latest packages. Well, we already have a version to test with Kernel 3.18 + firmware occupying 3 GB.

  • Snappy Ubuntu Core: Honestly what I have more desire to try as soon as I get the Pi2 is to test this minimalist distribution has also revolutionized the net these days. More info on Ubuntu website.

  • OpenELEC: Our favorite distribution for leisure and entertainment has been updated updating to the kernel 3.18 and it works really well as you can see in the video that accompanies the article.

  • OSMC: Formerly known as Raspbmc is another distribution to run XBMC based on Raspbian but still is not very optimized in its Alpha 4 release.

Raspberry Pi2 ejecutando Lakka
  • Lakka: The guys of this distribution based on OpenELEC to play emulators with RetroArch are looking for Beta testers on Twitter. For now and although it is not yet official, here you have daily builds for Raspberry Pi 2.

Available soon:

  • Retro Pie: We can't wait the new version adapted to the Pi2, although emulators in general are not ready to use multiple cores, so do not expect to see much better performance.

  • Android?: See this post from

  • Others: For other distributions that we use as Arch Linux, Pidora or Risc OS we also have to wait a few days or even weeks, but it will come.

  • Windows 10: It will take to arrive and not be a Windows to use as all imagine, but it sure we can use it for the IOT.

While I wait My Raspberry Pi 2 behind the door. Mr. Postman, if you're reading this, I promise you a beer if you are not late.

This week I've been disconnected from the news.

A couple of years ago, if some of us remember, my wife suffered a cerebral stroke which gradually recovered. This week she has had a very strong headaches and now is hospitalized. We don't know the origin of this sick, but medical specialist are studying, so I can hardly keep the ryth of the world. However, I have compiled the most important links of the week. From here I send the biggest hugs to my wife Elena, and the most tender kisses...

Fortunately, she is better and this Monday will practice a arteriography to watch if all is OK.

Time for a break

First of all, thank you for the words in the comments of the previous post. Medical specialist found something wrong and they have to operate the next Monday to my wife, so I'll be offline for another week, but I’ll try to publish my summary of news like every Friday. Thank you and apologize.

I've published an article about tools about make 2D videogames (in spanish), if you are interested or want to translate, you can find it here.

PiKISS will add support for ODROID-C1


For those who do not know, PiKISS are a bunch of scripts that I'm developing for the community. It lets you install software from a menu that is not in the repositories or compile it for you, easily configure static ip or your WIFI, mount a web server in minutes with little effort, among others. You will no longer need to write a command to the most tedious tasks.

I wanted to comment that soon I'll add support for ODROID-C1 and more specifically Ubuntu. I started refactoring the main code of the menu, so if you have it installed, I suggest that you run git pull to update.

More info: GitHub > PiKISS

Lakka new release for Raspberry Pi 2 & ODROID-C1


New version of which has become my favorite operating system for emulation. Updated the official version for all platforms and officially added Raspberry Pi 2 and ODROID-C1. The most important changes are...

On all platforms aspects such as shaders, cores and update packages are improved.

Raspberry Pi 2:

  • New snes9x-next, with better sound and compatibility

Known bugs:

  • Launching RetroArch is slow (10+ sec)

  • Launchin a game is slow (10+ sec)

  • The menu is laggy (30fps)

  • No audio on the N64 emulator


  • snes9x-next & pcsx_rearmed works flawlessly

Known bugs:

  • No vsync, so there is some tearing on some games

  • No N64 emulation, it segfaults on launch

  • The menu is too fast (130fps)

You can see videos for both platforms in the next link.


NetBSD & Ubuntu Mate for the Raspberry Pi

Ubuntu MATE

The Raspi has new OS, and now we are with ARMv7 seems that many distributions are thinking of a port and not just for our favorite board...

For NetBSD, the port comes both for the Pi and ODROID-C1. In this link you will find the latest stable version for the Pi. The funny thing is that they have optimized the operating system to use the GPU and support omxplayer, OpenGL ES, Quake 3 or RetroArch. Deserves a chance.

With NetBSD for ODROID-C1 is almost a piece of artisan and we must build image for ourselves. At least it's a start.

Ubuntu MATE 15.04 for Raspberry Pi 2 is based on the image of Ubuntu ARM (no Snappy Core) and still is a very early version, although fans of this distribution will see more progress over the month. I hope it will get support to the GPU to play videos.

CentOS community is working in a version to Pi2 and ODROID-C1 that we hope to see soon.

Docker-Pi for admins & developers

Docker Logo

As a developer, I have no choice to be the latest in terms of technologies, methodologies and new systems that make my day easier to carry the day. I use Vagrant and want to migrate to Docker, which is one of those technologies that I love him more attention. Is it worth it?

For those who do not know, Vagrant lets you create a separate virtual environment to your main operating system. The goal is for all developers working on a project basis and then there are no problems when launching the releases in the production center, for example.

Vagrant use VirtualBox. With a few commands, you have a virtualized OS ready to develop with your favorite language.

Docker is the same, but no need to create a complete virtual machine. It uses a small engine with a client and a server, and shares the kernel of your main OS, being more efficient.

Govinda Fichtner has created an operating system based on Raspbian for Raspberry Pi with Docker 1.5.0 and kernel 3.18.8. You will not have to install anything else. It supports OverlayFS, which in theory sweeps alternatives such as lvm or btrfs. Images to prepare a machine with Node.js, Java or Python should be compatible with ARM, but that they had already designed and created multiple repositories adapted to the ARM processors can be found in this link.

New Crispy Doom available to play Doom, Heretic & Hexen


Happy Pi day!

I spend all week improving my PiKISS project, and I noticed that the installed version of Crispy Doom is quite obsolete. A few days ago, has come a new version and I compile it to update my script, but that's not all...


To install the Commercial license, you must be the owner of a original copy

The time now is 8 in the morning here, I take from 3 awake, and more of a headache it has taken me to improve this script (Only tested on Raspbian). Features:

  • Install dependencies

  • Install the latest version of Crispy Doom 2.3, if not already installed

  • You can download the shareware or commercial versions of Doom, Heretic, Hexen and/or Strife

  • To play, simply type doom, heretic, hexen or strife or from the Desktop, choose Games and click on the game you want to play.

  • Compatible with Raspberry Pi 1,2 & ODROID-C1

Known bugs:

  • The Shareware Hexen and Strife versions does not work. I'll try to find another version that works.

  • On ODROID, maybe you must to play inside the desktop environment.


The script allow to you to install wads files. Enjoy!

If you want to install, go to the project on GitHub or download the .deb file you can find at the end of the post.

Remember if you have problems when run the game on the Pi, it's because you have not installed the patch for SDL. You should also run the following:

sudo dpkg -i libsdl1.2debian_1.2.15-8rpi_armhf.deb
rm libsdl1.2debian_1.2.15-8rpi_armhf.deb

Well. It's time to sleep for me...zzZZ

Quake 2 on ODROID-C1


We could already play Quake 2 on the PI a couple of years ago as I told you. Now I wanted to do the same with the ODROID-C1 board and to be easy for you, I've added it to the PiKISS repository. Now your fingers are save.

I want to thanks to Meveric for help to me with the ODROID-C1 support in this thread of the forum.


Install Descent 1 & 2 on the Raspberry Pi


I've added this game to PiKISS project. Enjoy!

New PiSNES for Raspberry Pi


Yesterday I had a problem with the port of Descent and I got in touch with his creator to fix it. Fortunately he solved and the port works great now. As a bonus, the script that I prepared yesterday install the HD textures and sound tracks in OGG format.

I also took the opportunity to update the script with a new PiSNES version based on snes9x with good news, and other not so good...

Starting with the not so good, I must say that at least for me, the port does not work in the Raspberry Pi Model B, but in the Raspberry Pi 2. Something curious because the SD card use in both boards is the same. I have already contacted the developer Squid to fix it.

What good is that works great. The new features are:

  • Support for two players

  • Compatibility with Xbox 360 controller, among others

  • Now use GLES2 instead of Dispmanx for post processing on the GPU

You can now update PiKISS with git pull and enjoy this update, or if you want to directly download the port, I leave the link below. By the way, I let you next game as a gift inside the script.

RetroPie 3.0 Beta for Raspberry Pi 2 & PiPlay 0.8 beta 9


We have available the first beta version exclusive for Raspberry Pi 2 of RetroPie whose function is to build your own retro entertainment system and play several of the most popular emulators. PiPlay also has a worthwhile test version...

How the hell I finished playing Zork?. Because is included on RetroPie. Click to enlarge

Changes on RetroPie:

  • Change emulators for the same platform or even apply different settings

  • Resolution is also configurable

  • New menu in EmulationStation with easy access to settings, configurations, file manager...

  • AdvanceMAME 1.2 (based on MAME 0.106), Rpix86 added again

  • Backup/Restore of individual gamelist/data and settings

Changes on PiPLAY:

  • Updated to the latest version of Raspbian

  • File Watcher scans and updates the games menu

  • Updated config controller

On RetroPie I notice that everything is very stable: Games like Quake 3, Duke Nukem 3D and Doom have all the necessary files to run Shareware version. With Raspbian behind, emulators move very fluid.

Time ago I didn't test PiPLAY, but the configuration system of controls has a technical and design that have left me surprised. In addition, the environment although somewhat slower than that offered by their competitors, does the job.

Next week we will have new version of RecalboxOS, a system that is becoming my favorite. Check it out.

Would you like I make a more thorough review of any of these systems?. What is your favorite?.

KODITorrent: Addon to watch movies & TV Shows through Torrent


Popcorn Time, Movie Box, TorrentTv, Flixtor,... are many and varied our options for streaming through the torrent protocol.

By chance I found this add-on that works perfectly on the Raspberry Pi and allow uncomplicated access to an extensive catalog with 720,1080 and even 3D qualities...

I had already comment on some occasion these alternatives, but don't gave me the expected result.

The menus are loaded faster on a Raspberry Pi 2 with no overclock. I've tested with OpenELEC 5.0.6 and usually takes about 40 seconds with a 20 Mbps connection to load on buffer.

HOWTO guide: sselph/scraper

Mame cubelindo

You can be a messy in your life, your sexual orientation or your room, but the vast majority have well cataloged our films & TV shows, and above all our ROM emulators: With its covers, description,... an odyssey if not exist tools like I am going to present today, called scraper.

Scraper in the world of emulators are those programs with the goal of search for us all the information about a game to present it in our Front-end favorite with the best looking possible.

RetroPie comes with a very powerful scraper programmed in Python, ES-scraper. Today I present an alternative programmed on Go simply called scraper, running on the terminal of your operating system.

[ Requisites ]

First we need to install the Go language. You have packages for any operating system, including source code on this link. I'll teach you to install it on any of them. At the time of publishing this article, the latest version of Go is the 1.4.2. According to the process, sometimes you don't get the latest version (is the case of Ubuntu), but no matter.

Mac (through brew):

ruby -e "$(curl -fsSL"
brew doctor
brew update && brew upgrade
brew install go

Linux, Raspberry Pi, ODROID (Ubuntu) (+ info):

Ubuntu/Debian: sudo apt-get install golang

Fedora, CentOS/RHEL: sudo yum install golang

For the rest of ARM boards, visit the next link.

Now download the source code and compile scraper:

mkdir ~/go && cd $_
export GOPATH=$HOME/go
export PATH="$GOPATH/bin:$PATH"
(Mac only) export PATH="$PATH:/usr/local/opt/go/libexec/bin"

go get
go build

[ Use ]

With scraper -help we can see all the available parameters. Click to enlarge

NOW you can use the program from any directory with ROMs, typing scraper in most cases. With mame ROMs, we will use scraper -mame. It is interesting to know some of the parameters. For example with ROMs for mame, we can use scraper -mame -mame_img "t, s" to download the title img or catch a screenshot if not find the first one.

scraper dir

Scraper generates a gamelist.xml file and the images dir

Once we have made the whole process, we would just to copy the images directory and the gamelist.xml file to the path ~/.emulationstation/gamelists/console_type on RetroPie, Recalbox or any project with EmulationStation.

To help you to know if failed to recognize a title, I recommend you when run the scraper, copy its output to a file with scraper > Games.txt and then cat Games.txt | grep 'ERR '

If EmulationStation have problems with recognize the images, execute the following command that point to the file gamelist.xml previously generated:

sed -i -e 's/.\/images\//~\/.emulationstation\/downloaded_images\/fba/ig' /path/to/gamelist.xml

[ Conclusion: The Perfect scraper ]

This system will save much time and effort to have all your ROMs with their pictures and some interesting info. It is a very valid alternative to the scraper that comes with EmulationStation, but more customizable. It takes a few seconds to recognize and download the information of each ROM. In my case (iMac), 685 ROMS has been scanned in 14 minutes. Now you can choose if you want to go from this...

Fixing PiKISS


I spend all day fixing PiKISS to the talk on the next week. I just wanted to comment in case you want to make a git pull.

Not only have corrections, some links failed, added new scripts and the damn error with the SDL libraries to which Raspbian has not yet uploaded an official solution... Hopefully not be too long.

DietPi for Raspberry Pi & ODROID-C1


I talked about DietPi before, A minimal distribution that now support ODROID-C1 boards. It have some apps to custom their own OS.

It's an idea I always had in my mind: Build a minimal OS. The user can choose what kind of software want to make the function of Media Center, Web/FTP server or emulators with RetroPie...

It has grown in performance since the last time I met, and now the concept is different. Initially we have a Debian minimal distribution (the size of the image is only 780 MB) with a series of pre-installed packages, which are:

  • Dietpi-config: Configure your board, you can overclock, configure networking, etc).

  • Dietpi-software: Install software (Look at the screenshot that heads this article).

  • Dietpi-update: Update the distribution.

  • Htop.

  • Ramlog (All logs in memory and uses less than 0.5MB of RAM).

  • Dropbear (SSH Server light).

  • Scripts preinstalled: treesize, cpu, update, logclear.

  • Automatically configures your network WIFI modifying a file in /boot/dietpi.txt.

For ODROID-C1, the list of software to install "ready to run" is similar to what we have on the Pi: Bittorrent Server, OwnCloud, MiniDLNA, phpbb3 (forum) or Web/FTP Server among others.

[ First contact ]

First the distro makes two reboots to increase partition size according to the capacity of your SD card. We see that loads the ntfs-3g driver and ask for the root user and its password raspberry.

Now give us a number of options:

  • Select software optimized for DietPi. Alerts you if you want to use a USB hard drive. This decision can not be changed in the future. It is recommended if you are using it to use BitTorrent, OwnCloud, Kodi, hindfoot, MiniDLNA. Among the software that can be installed, highlight the above, plus Modipy, Proftp, No-Ip, among others.

  • Additional Software: Vim, OpenSSH Client or Samba Client.

  • Configure the distro.

  • Go Start Install. Follow along in the process.

If you do not select any software, it will give you the option to boot a Debian Minimal, which is what I chose. The system reboots. Let's see how our system has run:

htop without installing any package. Click to enlarge

I found curious that when trying to log through SSH, tells me to complete the installation if I'm using DietPi-Software. It's a detail.

Dietpi SSH

SSH while DietPi-Software runs

The system takes just 21 MB of RAM. I going to run Dietpi-software to install LXDE + Kodi. I get a message if you want to start from boot any software selected. I say no and returns to the main menu. Go Start to install and then the Start Install button.

  • Begins to install LXDE (500 MB on the SD card) and takes about 41 seconds to install 415 packages. Phew, is the last time I do it.

  • Kodi 14.1 must take 145 MB and spend 30 minutes to install the software. From LXDE, it just take 11% of RAM.

Install jdownloader on Raspberry Pi


I do not usually use the Pi for my daily downloads, but I discovered that many of you it does: torrent, Emule, and few use hosters as Freakshare or uploaded. Today we will install jDownloader on the Raspberry Pi.

jDownloader, for those who do not know, is a cross-platform download manager developed with Java, which supports downloading through different hosters or direct download servers. As I said previously here, usually use plowshare (recently migrated from Google Code to GitHub) and sometimes the program is now mentioned, one of the best known.

Some emulators updated

Some emulators updated


Long time I had not entered my favorite section of the forums: Games. Today I found several updates and some additions did not know, like an Amstrad CPC emulator coming with an Alpha version very promissing...

Emulators have updated their binaries are:


  • Unreal Speccy Portable (ZX Spectrum), in version 0.064 includes the following improvements: gamepad support, able to browse files inside .zip archives,.szx/.rzx/.fdi support,memory leaks, uninitialized vars, etc. fixed | > Unreal Speccy Portable


  • uae4all2 (Amiga), Compiled by Chips, this version bring CPU frequency beyond 28 MHz, you can adjust the resolution by parameters and supports new joysticks. | forum


  • Picodrive 1.91 by Chips. Looks like this guy work hard to improve emulators that we already had. Good for him (and for us). In this case, he improve Picodrive compiled by Notaz with dynarec activated and OpenGL ES upscaling. | foro


  • CapriceRPI2 (Amstrad CPC) is an Amstrad CPC emulator ported by a Spanish guy using scaling GPU hardware and to be a first version looks pretty good. Valid for Raspberry Pi 2 only. |

Of course, I've updated and added these emulators to PiKISS along with some games so you don't have to fight a lot when installing.


Android Lollipop 5 on Raspberry Pi 2


Many wondered when reading this post, if it was true that we could run Android 5 on our beloved Pi2. A user has dared to compile and teaches us how to get it...

Android Lollipop 5 on Raspberry Pi 2

The truth is that there is no secret. As you can see in the video above, does not run as well as they should because of the hardware that has the Pi 2, but it's a start. I guess it still will not support hardware acceleration properly.

What we get before running in our Pi, a decent version of Android or Windows 10?

Ubuntu 15.04 released!


Right now I'm trying out the final version of Ubuntu operating system that has accompanied me many years, but maybe this is the latest version that I'm trying...

Link Yo download:

A few things to remember you: The first is that here you can get a script to burn the image to a USB disc or SD card from OSX Terminal. As simple as run ./ ubuntu-15.04-desktop-i386.iso and forget about convert the image Yo .img,etc...

Another thing is that I updated the Ubuntu Google Docs here where I have collected several post-installation steps.

Runs very slowly on a NetBook with 2 GB RAM, so erasing in 3..2..1

Before commented that perhaps this is the last Ubuntu I use as operating system, because Debian Jessie will be with us this weekend, and I think it's gonna be a version that will be worth try.

Update Raspian from Wheezy to Jessie


I've been all this time dealing with Debian Jessie on my Mac and I am delighted. Jessie now supports ARM processors, so it is very easy also upgrade our Raspbian distribution with little effort.

After the jump I'll teach you how...

By the way, if you want a script to help you when installing Jessie on your PC/Mac, I'm developing one here. You will find everything you need to install Chrome, Steam, Docker,... and adjust your computer so that you feel comfortable (bye bye OSX, at least for a while).

In the case of Raspbian, run the following commands as root:

apt-get update && apt-get upgrade && apt-get dist-upgrade -y
sed -i 's/wheezy/jessie/g' /etc/apt/sources.list
apt-get update && apt-get upgrade && apt-get dist-upgrade -y

Now to make sure everything works, run hostnamectl

Thanks to for the post.

Thinking about Windows 10


This week I want to change the section about the Pi World with some reflections about Windows...

Microsoft is doing the things really well. I remember the years from Windows XP and I could not understand what they were thinking when released Windows Me (Do you remember Millenium, don't you?). Since then it was downhill and without brakes, and perhaps some saw the light with Windows 7, but returned to the darkness with the Touch philosophy on Desktop and killing the Start button, but...

It seems Microsoft is looking for allies everywhere and in all communities. Some examples:

  • Windows 10 promises. Tell you a user who went from MSDOS to Windows, then Linux and later OSX.

  • Continuum for phones


  • Browser Edge (late, but we'll see how it unfolds)

  • Facilitate port applications from Android/iOS to Windows 10

  • Cortana (Siri's boyfriend)

  • Visual Studio multiplatform

  • Third-party apps developed with HTML and JavaScript to Office

  • Windows Store

  • Partnership with Arduino, the Raspberry Pi Foundation, and everything related with IoT (+ info)

HoloLens sounds more like concept art than anything else, but it is REAL... Fuck yeah!

What's now?. They are giving us pills and being pulled new versions of everything I've commented. So we can only sit down and wait... What do you think about it?.

See ya in the comments...

Making videogames for Amstrad CPC with Raspberry Pi/ODROID


I think you must feel retro, programming on a Raspberry Pi, a game for the Amstrad CPC listening David Hasselhoff.

For those who do not know, the Amstrad CPC was an 8 bit computer that marked trend between 1984 and 1990.

Today we will see how to install CPCtelera, an engine which has just released its first stable version and greatly facilitates the creation of games for this computer with C or assembly code.


8 bits logo

[ Introducing CPCtelera ]

CPCtelera is an integrated development framework for creating Amstrad CPC games and content which includes:

  • A low-level library with support for: graphics, audio, keyboard, firmware, strings, video hardware manipulation and memory management.

  • An API for developing games and software in C and Assembler.

  • Tools for content authoring (audio, graphics and level editing)

  • Multiplatform: It works on Windows XP, 7 and 8, and in Ubuntu / Debian, Arch, Manjaro, Elementary OS and Raspbian Linux distributions

His developer is a Spanish guy named Francisco Gallego (Twitter), among other contributors.

Running ./ after resolving dependencies. Click to enlarge

First we need to download the source code to compile it on your board. To do this, download and access to the stable version, or if you are a brave man, you can use the latest version from GitHub (I'm using the stable version):

wget && unzip -nq $(basename $_) && rm $(basename $_) && cd cpctelera-1.0.0/
# or use the last commit:
git clone && cd $(basename $_)

Now we install some dependencies: sudo apt-get install -y build-essential libboost-dev flex bison. On ODROID (Ubuntu) are already installed. Now you can invoke the installation script running the file ./ It warns you with the necessary packages and prepare your system to run the engine. On both Raspberry Pi 2 - 950 MHz and ODROID-C1, it has taken about 20 minutes to compile.

[ Starting the Engine ]


Coding like a PRO

We have everything installed. If we browse through the directories, we can see some interesting folders as docs/, which contains the reference manual, or tools/ to make sprites, compose soundtracks (Trackers), format converters, etc. Some of these tools are for Windows.

To create a new project from Bash, type:

cpct_mkproject [folder_project]

Now cd to the dir and you can see two directories:

  • src/ with the source code (the first time we just have a main.c). You can create files and directories of your game here.

  • cfg/ contain settings to compile the game through the file.

You have examples/folder with examples you can study. Just cd to the dir, run make, and automatically create .CDT and .DSK files. So cool, isn't it?!

[ Conclusion ]

Now it's your turn. I recommend you to start studying the examples in examples/easy/src, modify and compile it.

Remember that to get an emulator, you can install Caprice thanks to PiKISS for the Pi and test your creations (Do you know any emulator for ODROID?). At the end of this post you have a link to the reference manual with all the info you need to know about functions and methods available. If you know something about SDL, everything will be a little easier.

By the way, the developers accept donations via Paypal here.

News this week on Pi/ODROID World


This week has been much movement in terms of new boards. CHIP, with a cost of $9 (hopefully lower their shipping costs now that they have surpassed the million dollars on Kickstarter) has been the most we liked.

We can already can read the new issue of the ODROID MAGAZINE where I have published an article about how to install Quake II in ODROID. But... There's more!...


May issue. ODROID Magazine

  • Java ME 8 + Raspberry Pi + Sensors = IoT World Part I | Part II

  • ODROID MAGAZINE May: I could say that my article about Quake II is the best of the magazine, but I would lie: Install a classic RPG like Arx Fatalis (you will see a script to also install it in the Pi2 soon), emulate the Nintendo 64 or build a Dashboard to keep informed, are among the best you'll find in this great magazine |

Happy weekend!

LinkedIn help you to find a job


As you know, I am a freelance for a year and a half. Here in Spain and especially in my city, is difficult to find a job as Developer/Computer engineer being freelance and if so, is having contacts that "hold" you every month. So maybe it is time to seek paid employment.

I do not usually use LinkedIn (if you're curious, here is my profile in this network), but today I found that it have a fantastic searcher. If I want to focus on finding a job that makes use of my skills with Raspberry Pi, you can get a list with some companies interested in people with this knowledge, which today does not surprise me.

So if you want a job, you know that this social network can help you.

You're welcome.

Arx Fatalis for Raspberry Pi 2 & ODROID


In the May issue of the journal ODROID Magazine, you can read an article about how to play a classic RPGs with this board. I talking about Arx Fatalis.

If you had no chance to play this game, NOW IS THE TIME. Choose your board: Raspberry Pi 2 (Raspbian) or ODROID (Ubuntu).

Arx Fatalis @ Raspberry Pi 2

[ Arx Fatalis ]

"This critically acclaimed first-person RPG takes the player on an amazing journey into the fantasy world of Arx. The game mixes intelligent story with immersive and actual medieval surroundings. Arx Fatalis allows the player to feel that all his actions have a direct consequence on those around him. The goal of the game is to destroy the secret cult of Akbaa, the god of destruction. As a player, you must prevent the return of such a cruel creature to the physical world. Should you fail, Akbaa is bound to impose its terror upon the world of Arx."-Steam

It was developed by Arkane Studio, a French company that would engage us later again with the famous Dark Messiah of Might and Magic. This company has had many successes and many cancellations until the company ZeniMax Media acquired Arkane in 2010.

It can be purchased on Steam with text in multiple languages (including spanish).

[ Arx Libertatis ]


Don't you want to walk through this dungeon now that summer is comming?

This is the port based on the source code released from the original game. So it can be enjoyed on new platforms now and forever. The game runs with ./arx and also brings another file named arx-install-data if you have the original game and want to use the files needed to run. The configuration files are in ~/.config/arx/cfg.ini and the files for the game you must placed in ~/.local/share/arx/

The configuration file can fix some problems. If for example gives you the following issue when run:

X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  154 (XFree86-VidModeExtension)
  Minor opcode of failed request:  10 (XF86VidModeSwitchToMode)
  Value in failed request:  0xa4
  Serial number of failed request:  131
  Current serial number in output stream:  133

You must to change the line resolution="auto" to resolution="1280x720", or another resolution that your TV support.

[ PiKISS, to the rescue again ]

PiKISS Fatalis

I have taken more than a week refining and testing the script. I had problems with the Raspberry Pi 2 and some textures, but as you can see in the video above, is playable. Maybe it's the latest version of Raspbian I use the problem and the SDL libraries (who knows). In ODROID runs flawlessly. I have installed the game on Debian 8 and PiKISS added support to the game, and if I ever want to play in my PC, it does not have to worry much about the packages you need to install or where to get the .PAK files.

[ Conclusion ]

Arx Fatalis - Speedrun [00:48:37]

The game immerses you in a world underground with much emphasis on combat and spell system he had seen in other games like Anvil of Dawn or Stone Keep. Now you have the chance to play again.

Playing with OpenBOR


Captain America against the Green Goblin clones by OpenBOR

Who has not played Final Fight?. I have spent my teen small fortune on two things: Playing arcade games and buying computer magazines (MSX-Club, MicroHobby, MicroManía, PC-Mania and Arroba if I remember correctly).

OpenBOR it is an engine that allows you to play games in the genre Beat'em Up. Most games are made by users, but some have a really good quality.

Do you want to install it?... Jump then!

She-Ra and He-Man gameplay

Actually there is not much mystery. I've spare my precious time trying to figure out how to run once compiled, but as always, I give you all done so you don't have to suffer as I have done.

First, the installation: Either by PiKISS, or typing in the terminal of your Debian(PC)/ Raspbian(Rpi)/ Ubuntu(ODROID):

sudo apt-get install -y libsdl-gfx1.2-4
mkdir games && cd $_
tar xzvf openbor_by_ulysess.tar.gz && rm openbor_by_ulysess.tar.gz
cd openbor


Directory Structure

Inside you will find the executable for your favorite system. Now we need to seek on the internet the .pak files and copy them inside the Paks/ folder.

Once copied, run the script from the root directory called ./


Saint Seiya

You can find games (also called MODs) without the .pak extension. Never mind. The structure must be the same for all games. Here's an example:


Paks directory structure

Inside data/ we have the files that compose each game, but it is important to maintain this structure: Paks/name of the game/data.

Now we run the file corresponding to our system. For the Raspberry Pi is ./openbor_rpi to access the menu. You will probably see a very small box in the middle of the screen. Search video settings menu and play around with the resolutions.

There are users who prefer lower the resolution of their monitors and run it with the following instructions:

fbset -xres 512 -yres 384 -depth 16
SDL_FB_BROKEN_MODES=1 ./openbor_rpi

The game controls are: arrow keys, [A], [S], [D], [Z], [X], [C] and [ENTER] to access the menu.

Now you can hit to everyone who put in front of you. If any reader know OpenBOR and wants to show us some MOD for this engine, we wait you in the comments.

We already seen on the internet tons of articles about systemd Vs upstart. A war that has ended as always: It was adopted systemd by default in many distributions and we have not ever seen the end of the World.

Let's see how to take advantage of this new system to load daemons with a few very interesting commands and we can learn to improve startup times of our favorite distribution too.

[ systemd ]

systemd is a suite of system management daemons, libraries, and utilities designed as a central management and configuration platform for the Linux computer operating system.


About the eternal battle upstart Vs systemd I read on a forum something that perfectly sums up what I think of this:

"Both are good, they are a vast improvement over sysvinit, they are well documented, have good developers teams behind and users will not notice the difference".

[ Start/Stop/Disable daemons ]


If we really want to know the status of a service, we use systemctl status service name. For example, systemctl status docker

  • To activate a service, we'll use systemctl start service name

  • To stop it, systemctl stop service name

  • If you do not want to start with the system a daemon, systemctl disable service name

  • To start a process with your computer (boot), systemctl enable service name

All these commands should be run with administrative privileges (root).

[ systemd-analyze ]

It is a powerful analysis tool that will allow us to meet all processes that start with the system and the time it takes, among many other options. I leave you a list of frequently used commands:

  • systemd-analyze: It shows the time taken to boot the kernel and other processes.

  • On my iMac 27" mid 2011 and Debian Jessie installed and after a couple of months of use, the result is as follows:

Startup finished in 5.756s (kernel) + 12.310s (userspace) = 18.067s
  • systemd-analyze blame: With this command you get what processes take longer to start:

5.869s systemd-udev-settle.service
2.352s early-readahead.service
2.231s systemd-tmpfiles-setup.service
2.202s networking.service
2.176s systemd-journal-flush.service
  • systemd-analyze plot > file.svg: This command is interesting. It generates a .svg graph with a timeline of all processes started. I show you mine:

file.svg build by systemd-analyze plot. Click to enlarge

If you want to take a look at the entire file, what you have here: file.svg.

[ Another commands ]

This system processes management brings many interesting tools. I'd like to highlight the following:

  • systemctl -all: It displays the status of all the services you can use, separated by columns as UNIT, which shows the name of the daemon, LOAD, if loaded, ACTIVE if it is started or not, among others.

  • systemctl list-unit-files: Displays all units (daemons) installed and their status (static, disabled, enabled, masked).

systemctl status

  • systemctl status nombredelservicio.service: Displays the status of a predetermined service (see screenshot above).

  • systemd-cgls: Displays a dependency tree of parent and child processes (usually system.slice and user.slice).

  • ps xawf -eo pid,user,cgroup,args: Another way to show the processes.

[ Conclusion ]

Study the system boot from your operating system, it's to devote several books. the good point about Linux systems, is that if you dislike this management system, you can change it.

We have seen some of the commands so you can begin to defend yourself, but there is more, and I invite you to delve into the subject, if you like, and comment the article.

Exagear Desktop: Run x86 apps on Raspberry Pi & ARMv7 (Part I+Giveaway)

Exagear Logo

Would you like to install some x86 Linux apps on your favorite board?. Surely you've heard about Exagear Desktop, a payment software that allows you to launch applications based on x86 (32-bit). Maybe you have doubts about if it really works.

The company Eltechs has contacted to me to make a review about their product. 5-10% is difference between ExaGear v1.0 and v1.1. I know only one similar solution - Qemu. Performance comparing to Qemu is 5x (500%)!

Are you interested or curious about how it works?. I've seen comparisons and graphics in several sites about their performance, but nowhere have made real test running software. I bring the first analysis about this product and we'll see in the following two articles if it really worth. In addition, we are giving away 10 free licenses of Exagear Desktop.

[ What really about? ]

This solution implement a virtual machine (VM). It's a container for x86 applications inside a board with ARM processor. That is, you have a host computer (PI, ODROID, etc.), an a guest (x86 VM).

I'm going to test the latest version, Eltechs ExaGear Desktop 1.1.

[ Requirements ]

This product takes nearly a year on the market, and it is compatible with the Raspberry Pi 2. Now it brings support also for Raspberry Pi A/B/B+, and have gained support to other boards like ODROID, Banana Pi, CubieBoard or any with ARMv7 processor, as mentioned before.

The requirements what you need:

  • Raspberry Pi 1, Raspberry Pi 2, ODROID, CubieBoard, CuBox, Utilite, Jetson TK1, Wandboard, Banana Pi or whatever with ARMv7 support.

  • For applications using MMX/SSE, you also need NEON and vfp support. This technology called NEON handles multimedia accelerate algorithms in general: Decode video or 2D/3D graphics among others. You can check whether your motherboard supports running the following command: cat /proc/cpuinfo | grep 'neon\|vfpv3'.

  • Ubuntu 12.04/14.04, Debian 7 or Raspbian. Check your Ubuntu version with: cat /etc/lsb-release

  • binfmt_misc kernel module. You should also have it, but if you want to make sure, execute one of the following instructions and get a result, it means that is supported:

cat /proc/config.gz | gzip -d | grep CONFIG_BINFMT_MISC
cat /proc/sys/fs/binfmt_misc/status 

[ Installation ]


Files needed for ARMv7 devices

In my case, I have several packages: Raspberry Pi, Raspberry Pi 2 and for ARMv7 processors. As you can see, it will install a virtual image adapted to the operating system that you have installed. That is, if your operating system is Raspbian, the installer will use an x86 Raspbian image as a guest.

There are two installation methods:

  • Automatic Installation: Run / as root in the directory with packages and copy your license key file on it (important). The script will make a series of test and will begin installing the necessary packages:

# ./ 
System memory configuration is determined as 2g/2g
HOST OS: debian
EXAGEAR package: exagear-mem2g_*-1_armhf.deb
EXAGEAR guest image package: 'exagear-guest-debian-7-wine2g_*_all.deb'
Installing prerequisites...
Installer on Raspbian with a Raspberry Pi 2

Exagear Desktop installing on ODROID-C1. Click to enlarge
  • Manual Installation: Following these steps.

sudo apt-get install -y bash coreutils findutils realpath curl binfmt-support cron  
sudo dpkg -i exagear_.deb
sudo dpkg -i exagear-guest-.deb
sudo cp  /opt/exagear/lic
sudo /opt/exagear/bin/actool

Ready!. Application is installed together with the packages needed to run everything correctly. The image what really does is expand in the directory /opt/exagear/images/\, the guest system. So, once we are inside the virtual machine, you will really work in that directory (similar to chroot command).

[ First steps ]

To ensure that the image that we installed is Ok, we can use command-ls. If you have a ODROID board, it shows you:

Installed guest images:

To access the guest system, you must type exagear:

$ exagear
Starting the shell in the guest image /opt/exagear/images/ubuntu-1404lts
$ uname -a
Linux odroid 3.10.79-87 #1 SMP PREEMPT Wed Jun 3 14:57:54 BRT 2015 i686 i686 i686 GNU/Linux

Eureka, you have your own x86 VM running!. It was very easy to get here. To return to our guest operating system, type exit

One detail to note is that users share the guest machine to the host computer. That is, within the VM, have the same users and the same folder /home that in your main operating system.

[ Giveaway ]

You have arrived at the end of the first part of this review. If you like to try this software, Eltechs has been kind enough to give 10 free Exagear Desktop licenses for readers of this blog. The rules are simple:

  • Share a message on Twitter, LinkedIn, FaceBook or Google Plus with the next text: "I want a free license of Exagear Desktop to My Raspberry Pi/Odroid/cubieboard (or whatever you want)". That is, if you want a license for your Raspberry Pi 2, would be: I want a free license of Exagear Desktop to My Raspberry Pi 2. You can see the supported boards on the official website of the product.

  • Send the link you have just shared to the e-mail:

  • Only one email per person and social network is allowed, so you can participate a maximum of 4 times.

  • It is optional, but if you want, you can follow us on Twitter: ulysess10 | Eltechs

  • You have until next Sunday 14th to participate.

Good luck!

Exagear Desktop: run x86 apps on Raspberry Pi & ARMv7 (Part II)

Exagear Logo

We have learned a little about running this software, its installation and how to run it. Today we are going to execute a virtual machine and some programs.

Remember that we are giving away 10 free licenses of Exagear-desktop v.1.1. (more information in the first part of the article).

[ Installing applications ]

What is the best way to install an application in Debian?... Exactly!, through apt-get:

sudo apt-get update

sudo apt-get update on ODROID-C1. Click to enlarge

In the screenshot above we can clearly see how the system is updating from 386 repositories. Not all commands are supported, for example, you can not use apt-get dist-upgrade.

As I said, both host and guest, shared user folder, and you can copy files from one machine to another.

In Raspbian, the best is modifying the file /etc/apt/sources.list that comes on the guest system, so you will have a broader catalog and updated software for testing :

deb wheezy non-free contrib main   
deb wheezy-updates main contrib non-free 
deb wheezy-backports main contrib non-free 
deb wheezy/updates main contrib non-free 
deb wheezy main non-free 
deb wheezy-backports main 
Example of /etc/apt/sources.list for Raspbian or Debian based

On ODROID boards, I'm going to install an application using PPA that I use in my daily life: The file manager Double Commander:

sudo add-apt-repository ppa:alexx2000/doublecmd -y && sudo apt-get update && sudo apt-get install -y doublecmd-gtk

Double commander it works perfectly on a ODROID-C1. Click to enlarge

Fantastic!. The program behaves as it should, and now I can manage all my file operations with this Total Commander's clone. It have been easy, haven't it?, How about trying a game?. In this case, I opted for one that you can find in the official repository: Armagetron Advanced.

sudo apt-get install -y armagetronad

Exagear can't run 3D games decently. Click to enlarge

The game has not recognized me the GPU in ODROID, perhaps due to a conflict and only reach 6 fps. On Raspberry Pi 2, I get a black screen and does not start, as you can see in the capture.

I'll try VideoLan:

sudo apt-get install -y vlc

After a while installing dependencies, and execute on both boards where I've tested (ODROID-C1 and Raspberry Pi 2), the display is shown in black when I play a .mp4 file. I have tried several video codec, but none of the supported work. Anyway, I had to try.

Since I'm a person with habits, my development tool is Sublime Text. Let's try to install & run:

tar xvf Sublime\ Text\ 2.0.2.tar.bz2

Sublime text 2 on a ODROID-C1. Click to enlarge

It works flawlessly, which is appreciated if you are a developer.

[ Wine ]

Let's do the real test and that surely will be willing to try: I'm going to test Wine. As you all know, Wine (Wine Is Not an Emulator) allows the execution of programs to almost all versions of Microsoft Windows under Linux.

sudo add-apt-repository ppa:ubuntu-wine/ppa -y && sudo apt-get update && sudo apt-get install wine1.7 winetricks -y

On Raspberry Pi (Older version):
sudo apt-get install wine winetricks -y

After installing a few dependencies. The first thing that occurred to me to install is a SNES emulator called zsnes, which has always been and will be my favorite.

zsnes. Click to enlarge

The result, it works almost perfectly. It is playable, but I can not put the emulator in full screen.

I don’t test much apps, only a few works. I guess my failures with wine are mainly due to each application requires a series of internal settings (native dll, optional parameters, ..), and there are some applications under Wine that does not work, such as Media Player HC, Internet Explorer 8/9, iTunes 10... My advice is that if you need to run a particular software, make sure it works on your PC with Linux before.

I’ll try more apps and expand this section in a future.

[ Conclusion ]

Exagear Desktop does what it promises: Run x86 Linux applications on ARMv7 processors. When you see that an application works with another architecture on your board, it looks like magic. It's common to run emulators of other machines and older consoles in this kind of systems. The same is done here. A curious fact is that I thought the processor would be 100% loaded whenever running a virtualized application, and barely reached 60% load. After spending several days trying it, I can draw the following conclusions:


  • If you have an application that you use on your PC and you don't want/know to compile it, or It is not available, this is the ideal solution.

  • Faster than other solutions on the market.

  • Very easy to install and use.


  • Almost all software I find, can be compiled natively on your board.

  • I hope you have a good Micro SD card and that contains at least 16 GB.

  • Don't you expect miracles or run PC games requiring 3D.

  • Obviously, in the Raspberry Pi 1, does not go as smooth as the Pi 2. I notice that, with a ODROID-C1, all the job is done smoother and faster, it perhaps due a more powerful CPU. Perhaps with the ODROID U3, we can't notice the difference between a native application or another virtualized.

That's all, folks. I'd like to make a video so you can see the load times or other aspects that may interest you more than me, but I could not because of time, but it's pending.

If you want to express your impressions or you want that I try some software in particular, use the comments below.

I hope it helps you.

Happy weekend!

Arch Linux + LAMP


Lately I suffer distrohopper. This has force me to install Manjaro, based on Arch Linux and leave a little aside to Debian, with whom I was delighted, but with Manjaro was love at first sight. I did not think that an operating system could be as fast on a computer that is already 4 years.

So back again and configure everything from scratch. This time I've installed Apache+PHP+MariaDB, the trouble is I did not know I was going to give so many headaches.

For this reason, I decided to leave here some notes to configure and have a reference for the future, because several guides that have followed, have not helped me a lot.

Here we go.

First you must to install the required packages:

sudo pacman -S apache php php-apache php-mcrypt mod_fcgid openssl mariadb mariadb-clients

I tried to avoid the AUR repositories to improve system stability.

We configure MariaDB. No matter if your databases are in MySQL or your connections are to this database. It's compatible.

mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
mysqladmin -u root password 'mypassword'
systemctl start mysqld

Now modify the file /etc/httpd/conf/httpd.conf (Here it's the majority of problems). I recommend making a copy of the file:

Add # at the beginning of the next line:

LoadModule unique_id_module modules/

Remove # on:

LoadModule rewrite_module modules/

Raspberry Pi and the IoT


This weekend surfing the web, I found a very interesting guide about the Pi and the IoT (Internet of Things), where you will learn among other things...

  • Learn the fundamentals of using a Raspberry Pi (booting up your Pi, using the Linux command prompt, remotely logging into your Pi, etc.)

  • Wire up simple circuits using a breadboard (no previous experience required)

  • Write and run simple Python scripts that will run on a Pi (no previous experience required)

  • Build multiple live Internet of Things projects that stream data to a cloud service

Banana Pi CookBook

Banana Pi cover

Has recently go on sale this book that collects 25 interesting recipes for Banana Pi.

I've participated in the elaboration of each chapter of this book, and I can assure you that it a MUST HAVE If you have one of these boards.

After the jump, I tell you what it's about.

What You Will Learn:

  • Discover how to configure and maintain your Banana Pi device

  • Install Android and a Linux-based distribution onto the Banana Pi

  • Attach external drives to your Banana Pi by using the USB or SATA interfaces

  • Install and configure common server applications and multimedia applications on Linux

  • Share files between your Banana Pi and other devices either in your internal network or over the Internet

  • Set up a secure web stack and run blogging software on your device

  • Connect remotely to your Banana Pi using SSH and VNC

  • Build simple electrical circuits and connect simple hardware elements such as LEDs, resistors, buttons to the GPIO pins

  • Configure a multimedia centre that is able to play high definition content

Its author is called Ryad El-Dajani and I think that is among the first to achieve great progress when set within the major operating systems available, features such as graphics acceleration, XBMC or create one of the best Arch Linux distributions on this board.

From here I wish luck to the author, it has been a pleasure working with you.

Recover files on Linux from NTFS partition

ntfsundelete logo


I usually have a NTFS partition to share files between OS X, Windows and Linux. Without wishing I deleted some files from this partition. Today I'll try to recover it without installing any software on my Linux distribution and in four easy steps...

There are too many file recovery programs. My favorite is TestDisk, but it's not for everyone. Today I'm going to show you how to recover files with an application that is already installed in most Linux distributions. It is ntfsundelete.

sudo fdisk -l. Click for enlarge

1) Unmount the NTFS partition: If you don't know what is it, use the command sudo fdisk -l. Now create a directory where the files will be recovered and cd into it.

2) Run the following in the terminal:

sudo ntfsundelete /dev/sdaX | grep 100% | awk '{print $1, substr($0, index($0,$7)) }'

Where X is the NTFS partition. You will see the files that have a recover probability of 100%. If you don't want to be so strict, delete the previous pipe | grep 100%. I used pipes to display the data that really care.

.png files list deleted. Click to enlarge

If you just want to recover such files with extension .png, add the parameter -m *.png to ntfsundelete.

3) Now we have several recovering ways. I'll try to recover the file gpu_performance.png:

  • By Inode: The first column shows the Inode. We would type:

sudo ntfsundelete /dev/sda5 -u -i 11812
  • By file name:

sudo ntfsundelete /dev/sda5 -u -m gpu_performance.png

Supports wildcards, so to retrieve all .png files, we must to use -m *.png

  • By time: In this example, we retrieve all files two days ago (2d).

sudo ntfsundelete /dev/sda5 -u -t 2d

You can use d, w, m, y for days, weeks, months or years ago.

Perfectly recover the file and change the permissions. Click for enlarge

4) Change root permissions: Finally, we recovered the file as root. We need to change the permissions:

sudo chown your_user *

I hope it helped you and if you see me, buy me a beer.

I had one of those productive morning looking for new ideas for the blog, which I will explain soon, and I have also gathered a lot of information for future post.

Today I want to comment the changes on a new version of this emulator for MS-DOS to the Raspberry Pi.

This version contains the following fixes and improvements:

  • Implemented missing FPU opcodes (TradeWars 2002).

  • Implemented JPE/JPO opcode hacks for TradeWars 2002.

  • Fixed DMA current register off-by-1 problem (Tyrian 2000).


Happy birthay to me!


Well, today is my birthday, so I have to take stock.

It has been a year with many emotional changes, I guess like everyone. Fortunately, today I live where I want, with the people I love and I love my profession, so my wishes are for:

Thinking that my wife has recover through an operation and everything went well, I'm looking back and see that we make the right decisions at the time. For Elena, I want that you keep trying to be more optimistic about life.

Laura, my daughter, I see you growing every day, and every year I think I live with her the best time and I'm around to see it, which is important. I wish you hapiness. I hope you never miss how affectionate you are with your family, who adores you.

To my parents, I can count on them and they with me, I wish they can live with us all the good/bad thing that around us. I am proud to have you.

To my friends, that I have something forgotten because my work, they know I will always be there, and whatever happens, I remember you every day. I want you to see life with the same light that I see it.

And you who read me, known or not, coming from all parts of the world, I can never thank you who have been there for reading. For you I maintain this blog and I wish it for many years.

I keep blowing the cake, fulfill years and have more experience, but will remain the same imaginative boy, confused, optimistic, entrepreneur and dreamer who you have always known.

BBC Micro:bit


Yesterday came out in almost every digital media and we continue receiving news about this new board have been made from the BBC quarters in collaboration with 29 companies, of which highlights some as ARM, Barclays, element14, Freescale, Lancaster University, Microsoft, Nordic Semiconductor, Samsung and the Wellcome Trust.

What it gives this board that is interesting?. I'll tell you after the jump...

The first is that sixth graders pupils from UK will receive one of it free of charge (This means about one million boards).


Let's check out some features:

  • Size: 4x5 cms

  • ARM Cortex M-O processor

  • 5x5 LEDs matrix

  • 2 programmable buttons

  • 1 accelerometer

  • 1 compass

  • Bluetooth LE

  • 5 I/O rings

  • 1 USB

This board alone does not make much sense to us and is more like an Arduino that other board, but imagine what you can do together with the Raspberry Pi.

It will be available in October and I have not read anything that is to be put up for sale, although being Open Source development, any company will.

ODROID-C1 manual

ODROID-C1 manual

Many times when we buy one of these boards, inevitably we downloaded an image and we start to tinker with the operating system, to see the performance that has our new acquisition.

Now it's time we take a look at a comprehensive free manual prepared for the C1 and this is quite complete.

The author of this document is Rob Roy, Chief Editor of ODROID Magazine.

The good thing about these books is that many of the tips and guides that are on the inside, perfectly can be extrapolated to other boards as the Raspberry Pi.

ODROID-XU4, new board XU3 compatible for $74


It seems that there is no summer for Hardkernel guys. While the ODROID-C1 stock is sold, new PCB come to scene. I present you the brand new ODROID-XU4.

ODROID-XU4 Hardware Introduction

I hightligh the next features:

  • Size: 82 x 58 x 22 mm approx. Weight, 60 gr with fan

  • Samsung Exynos 5422 octa-core with 4 Cortex-A15 CPU cores and 4 ARM Cortex-A7 cores

  • 2GB of RAM, HDMI, Gigabit Ethernet

  • Mali-T628 MP6 OpenGL ES 3.0 / 2.0 / 1.1 and OpenCL 1.1 Full profile

  • 2 USB 3.0 + 1 USB 2.0 port

  • No Jack or DisplayPort

  • Support Android 4.4 & 5.0, Ubuntu 15.04 and all OS for XU3

  • Power supply 5V-4A


The price included built-in fan and power supply. If you go to the product page, the numerous benchmarks speak for itself. I would emphasize speed of eMMC 5.0 and is an ideal for NAS or use it as Desktop PC, due to their high rates of transfer. The downside comes with the international shipping cost, amounting to $25, so at the end you pay for the board $100 dollars (about 90 euros).

Still, I think it is a very full board and in the context of price where it moves is hardly be beaten.

ODROID-C1+ parts
  • Change the HDMI connector to Type-A from Type-D.

  • Improved SD card compatibility

  • CEC function without RTC backup battery

  • Power path from USB OTG port as well as DC-Jack

  • Expose I2S signals for external audio DAC

  • Price: $37 (34 Euros)

Actually I consider the ODROID-C1 has a great value for money. Soon I will have the ODROID-XU4 in my hands, so I'll do the corresponding unboxing and will take several benchmarks.

Introducing OTTO, the camera with Raspberry Pi inside


The Next Thing Co. guys succeed with each project presented. It happened with C.H.I.P. I already mentioned here and it was not the first. It was a campaign that helped found the product I'm presenting today, which is nothing more than a camera created with the Raspberry Pi Compute Module. A curiosity with which you can take pictures, videos, GIF and more...


Something it has captivated to me. Maybe it's their shape retro or its interior. It has a smartphone app where you can import your creations via WiFi and unleash your imagination to compose and share GIF, timelapse videos, etc...

Yes, this can be done directly with smartphone even better and with more quality (and cheaper). I guess for those who have grown up with cameras like Polaroid, has some charm and romance.

In any case, I leave you with some links to meet this Open hardware creation that you can hack.

Minimal Debian Wheezy+Plex on ODROID-C1


I celebrate the 600th post today, so I took the opportunity to make a tutorial: I have proposed creating a Plex server to share home videos that I have through my network. Obviously I will use the C1 because the Gigabyte Ethernet card, but is perfectly valid for Raspberry Pi.


We will use for our C1 the image of minimal Debian Wheezy that you can find in the official forums. If you have the Pi, any Debian distro is good for you.

Gparted for resize the SD. Click to enlarge

To resize the partition on SD, we will have to use Gparted on a PC running Linux.

Access through SSH. Click to enlarge

Insert the SD in your board and access via SSH to the operating system. The root password is odroid.


In my case, I followed a tutorial on HTPCGuides where everything is explained in a way very clear. Basically you have to run this steps:

apt-get update
apt-get install libexpat1 ntfs-3g -y
apt-get install apt-transport-https -y --force-yes
wget -O - | apt-key add -
echo "deb wheezy main" | tee /etc/apt/sources.list.d/pms.list
apt-get update
apt-get install plexmediaserver -y

Warning, I changed the repo article from jessie to wheezy.

Done!. Now access from a PC to the following address http://ip-ODROID:32400/Web and you will see a control panel like this:

Web access from Plex. Click to enlarge

If you need to restart the daemon: service plexmediaserver restart

If you use another operating system, you must mount the flash drive you want manually or install the package usbmount. With hard drives, fdisk -l and add your partition to the file /etc/fstab.

Adding partition to /etc/fstab. Click to enlarge

Now click on the left menu option + to add content and... Enjoy!

[ Fix: Plex Media Server 'is not powerful enough' error ]

Come back to the server through SSH and run the next commands:

cd /var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/Plug-ins/WebClient.bundle/Contents/Resources/js/

sed -e 's/validateTranscoder:function(e,t){if(!e.canDirectPlay)/validateTranscoder:function(e,t){return false;if(!e.canDirectPlay)/ig' ./plex.js

[ Other tweaks ]

Although you can play multimedia content now, it is important to set some parameters to provide an extra security layer:

  • Create an account on Plex website and add your user to Settings > Server > General. This allow you for example to log in remotely.

  • Change the Plex computer name: It is done from Settings > Server > General > family name

  • Rename the host: For security reasons with the following command:

echo "new_host_name" > /etc/hostname # Where new_host_name is the new name of your host
  • Also check the file /etc/hosts to change the old name for the new.

  • Would not it be interesting to have a read-only operating system to avoid corrupting the SD and cutting power shutdown?. You can use another distro that comes in the forums or follow the manual that I made and you can read here.

  • Check out also the advanced settings.

[ Download the client ]

We have the server ready, but now, according to the device where we go to play the content, we have to install a client. Here are some free except for the iOS version:

Link: Android (Google Play) | VLC

Link: Plex for iOS (App Store: $4,99) | VLC

Link: Windows 8

More: Other platforms

[ Backup ]

Anything can happen, especially SD corruptions, and create the database can take hours, even days. It is best to back up the folder that is hosted on /var/lib/plexmediaserver/Library/Application Support/Plex Media Server. It is as simple as running where you want (creating an alias, a file or scheduled task) the next:

tar rvf /root/ibackup_$(date +"%d%m%Y").tar /var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/

[ Ending words ]

The truth is that it was a good idea to rely on this media server and regret not having used it before. The ease with which you set up everything and how well it performs in the network, make it the ideal partner for this kind of boards. I hope you liked this guide and now you can enjoy your media content.

Finally, after weeks of waiting, finally I got my ODROID-XU4. At first contact, I have feelings for three reasons: A small problem I had to boot from the eMMC, due connect a keyboard through the USB port 2.0, the fan noise (which I'm not used since working with iMac) and Ubuntu Mate, which is not yet mature to be used with this board. Otherwise, it behaves almost like a desktop computer in speed according to some tests I've done.

While I encourage to do some benchmarks, let's see what has happened this week in the Pi World...Let's go!

Compile with the next sentences:

git clone && cd moonlight-embedded

git submodule init && git submodule update
make -j5

We pair with nVIDIA Game Streaming: ./moonlight pair PC-IP. PC-IP is the IP where you have the card.

Once you have entered the PIN has given in your PC, you can add in nVIDIA Experience a short name to the game you want on Settings > Shield and type in your ODROID the following to start playing:

Thinking about Windows 10 IoT Core for Raspberry Pi 2


With the arrival of Windows 10 on your desktop, we had almost forgotten the leap it has made in a few months in the world of development boards. Not what we expected, because having Windows desktop in our beloved Raspberrys is elusive dream, but we must not underestimate the great work they are doing with Windows 10 IoT Core, which today will reflect a little.


As much to say that its Core has been released, it is still a beta and still take to get a stable version from the official website of Windows > IoT can be seen the projects being developed for the Internet of things: Weather Stations, robot kits, accelerometers...

What is interesting, firstly fusion hardware we all know, with development environments that have accompanied us throughout life as Visual Studio. They give us everything so you can develop an ecosystem that just works.

In this post I will collect interesting articles to use Windows Core. I recommend that all of this technology not lose sight, because the future as I see, is wearable devices, and especially the IoT that fortunately you know what means, and most people walking watching a screen in their hands, not yet.

Godot Engine on Raspberry Pi


One of the passions (frustrated) I have since childhood, is the creation of video games. You can read an article here I wrote a while.

SDL has always been the best choice, but I have little more than a year watching the progress of a game engine called Godot Engine that has nothing to envy to Unity or Game Maker, and it works. The best, the user x1212 is porting the engine to the Raspberry Pi with surprising results (See the video below)...
