Happy B


I don't consider me a blogger. Or maybe I should ask what this word means to me. I see as follows: Members of a group (ie programmers, makers, chef, etc...) that reflect their progress/advances in a blog. Most share their code or cookbook so that it can improve together.

I didn't have any exciting project for so long. The path of a Freelance is not being an easy way and I spend all the time writing code or learn how to improve it. Maybe a don't manage my time well and having digital Diogenes syndrome can't help, or lose my time finding content that is not mine to save it "because can be useful in a future". That's the goal I've always had with the blog and Google Docs. Fortunately, in the way I have met many of yours. A few comments in articles, any conference when we met, for me was worth to continue with the blog.

This reflection that looks like a goodbye, it is quite the opposite. Today is my birthday, so I will try to propose me some goals, just because I'm tired of my routine and still expect me to stay half a century of life to prosper in all areas, especially as a person and developer.

I still want to thank you all, from the bottom of my heart. Here I will continue to inform you and make an effort to offer more quality content.


Getting Started with Electronic Projects (free epub)


With Getting Started with Electronic Projects, you will create several popular electronic security projects. This practical and accessible guide will show you more than just building handy and useful electronic security projects.

What You Will Learn:

  • Build an infrared beacon with the LM555 timer for someone interested in night vision.

  • Develop a motion detector using a mercury switch-activated car alarm sensor.

  • Redesign your PC sound card into a real oscilloscope and signal generator.

  • Build an RF power meter with some RF assembly techniques and programming skills.

  • Use several ZigBee devices and a BeagleBone to create a wireless network of alarm sensors.

espresso-arm: PID Espresso Controller + Siri


Projects where you join a bunch of technologies that seem so disparate, fascinate me. Hallee has been playing with his espresso and managed to make it work through Siri, hacking it with a ODROID-C2 (Although could also use any SBC).

As operating system, He used Arch Linux and technologies we already know: GPIO, Python and something I did not know: Homebridge in a Node.js server using iOS HomeKit API. All the details below.

News this week in the Pi World


I spent almost two weeks with a cough-runny nose and for me, it's not normal. I went to the beach, avoided air conditioners, rest at home, but nothing. I hope not to be another week like this. If you see me on the street, do not go near because this virus is heavy... Fortunately you can read comfortably at home and find out what I've been doing...
