An Open CVMeter

Did you know that most ceramic capacitors lose up to 80% of their capacitance near their voltage ratings?

My Business Card v2

At the end of this month, I'll be leaving my current job. I therefore thought it'd be a nice occasion to build a new business card for my future interviews:

A Personal Perspective on Managing an Open Hardware Project

I'm sure you must have noticed by now that during these last months I didn't put many projects on this blog. This is mainly because I'm currently working on the Mooltipass project, an offline password keeper idea I launched last december.
I've written articles on Hackaday about the technical aspects of this project, but none about my personal experience managing a team of contributors from all over the globe. I feel it's something that only has its place on my blog, so here we go...

Indoor solar energy harvesting: a platform to (finally) get some numbers

Means to extract solar energy are not new, but I'm still not seing anything solar-powered in my everyday life... Why is that so ?
Moreover, when you're trying to get some numbers on how much solar energy you could expect to harvest in an indoor environment, well... you basically don't find anything either...
So, let's build a platform that can finally give some info about the possibility to use solar energy to power your projects :) !

RGB led matrices with animated gifs

Hey guys, I just came back from a trip to China! Not only was it an occasion to visit this vast country but also a good opportunity to go to the numerous electronics markets in the cities of Xi'an and Beijing. Yes, even on holidays I'm still into electronics ;-) .
So here are the few interesting things I brought back, and especially what I did with them...

Electronic projects and Matlab

I have to admit, I am usually not the biggest fan of interpreted languages and high level programming. But in this case, they were very convenient.
This is thus a small article about what you can do in 3-4 hours with Matlab and a FTDI USB connectivity to your project. As an example, here is a project where my webcam output (well, kind of) gets displayed on my led matrix:

The Engine Control Unit monitor project

It has been quite a long time since I last posted a project on this blog... for the good reason that I am going to detail here for you guys!
So in this article you will see a quite complex project I have been working on for at least 6 months, which is an Engine Control Unit (ECU) monitor...

The FPSLIC matrix project

So... here is the famous project I was telling you about!
I'm pretty excited to explain it to you as I have been working on it for quite some time now (mainly because of license problems regarding the FPSLIC System Designer software): the FPSLIC matrix project.

RFID communication between 2 boxes

Hey guys!
It has been quite a long time since I updated this blog. Sorry for that, and to make up for it I'll describe here the technical details of a project I made for Logitech. I'm sorry but I won't be able to talk about the final goal of this project as it has to stay confidential. However, you may not need to know everything as the principe of the system is quite simple: do some RFID communication between 2 boxes.

The RGBW lighted carved plastic glass and its power supply

Being a DJ and loving to play with LEDs, I thought of a small project to realize during my third year in my french engineering school. The idea is pretty simple: light a carved plastic glass with RGBW LEDs located on its side. Let's see how this goes...
