The capacitive sensor
4 May 2017
But when Madame saw the rgb led strip I was testing, priorities changed.
– Let’s use it in the kitchen! And I want to be able to manually light it up.
Alright you know what it means. Let’s go working!
First try : Proximity Sensor for Arduino
I first tried to use the Proximity Sensor I bought with a Sensor Kit for Arduino. I wanted to detect the movement of a hand below the sensor.... Read More
Image resize / editing
1 May 2017
Let’s imagine, for example, that you own a blog and you sometimes write a blog post.
You may need to resize your images or create images thumbnails in batch.
ImageMagick is a program/lib that can create, edit, compose, or convert bitmap images. It provides many usefull scripts that can help you.
Mogrify is one of them. It provide an easy way to processing your images.
Let’s make some thumbsnails:
Once you have all your images in your directory create a

iot4i first release!
30 April 2017
Last week I told you about my new project, the scotchshelf, a rgb wooden shelf.
I worked on the digital part of the project, and the iot4i project is born!
You can find two projects in the iot4i group on gitlab:
- the iot4i/controlcenter that is the web app that will help you to manage the IOT.
- the iot4i/firmware that is the esp8266 microcontroller program.
The first milestone had only one business feature : we wanted to set the current color from a web browser, and see that the led strip bright with this color.... Read More
IOT devices inception
25 April 2017
Let’s talk about IOT.
In this post I said I wanted to learn how to use Arduino compatible micro-controllers.
Do you remember the dream layers of the movie Inception? What I discovered is almost as disturbing. There are a ton of available chips, and each chip can be integrated in a ton of module boards, and those module boards can be integrated on other development modules…
So to make it clear in my mind, I proceeded by choosing the chip first, then the module, and finally I found what I wanted with a development board.
And that is my feedback.... Read More

HUGO Static website engine
16 April 2017
Back in the club with a quick little feedback on HUGO that is the static website engine that runs this blog.
I started to work on HUGO yesterday, so I can only tell you what I feel after few hours.
Let’s go back few month ago when I had a try with Jekyll for the recalbox.com blog, an other static website engine written in Ruby, but I was not convinced. The thing was too low to compile, and too complex to run, even with Docker. I made a quick homemade blog engine for recalbox.
So what do I like so far with HUGO :... Read More

I decided to make this blog to share with anyone who would be interested feedback on :
- what I do for living : Software Enginner in Scala/Java and everything.
- what I do for fun : recalbox and D.I.Y. things.
