The pollux project has been a project I’ve worked on for two years with my friend and colleague Kasey. Today, that project has been released as FLOSS/OSHW with all sources on github. And it is also featured on hackaday. And that rocks!… ≫
Two years after the first try, I have worked on a few other electronic prototypes and now I think I have the experience I missed a few years back to put the prototype together.… ≫
I need to use the SL030 RFID reader on linux (on a beaglebone with i2c support enabled, of course). But when I tried to communicate with the device using i2cget, the device failed and disappeared from the detected devices… After the break, we’ll see why and how I solved it.… ≫
For a project, I needed to have a simple way to make a central software be able to send commands to several slaves appliances that are on the internets, i.e. they can either be on Internet with a public IP address, or be behind a proxyfied-firewalled private network that can only communicate through port 80. That’s how I came across a W3C working paper about a very simple technology based on HTTP/1.1 long-polling, called EventSource. The full story and real code after the break…… ≫
I got my hands on a msp430 launchpad to play around with it, and unluckily, the launchpad does not play nice with MacOSX 10.6. After the break, you’ll get my tutorial to make it work.… ≫
Je me suis depuis peu inscrit au statut auto-entrepreneur, et évidemment, j’ai vite eu besoin de sortir une facture. J’ai cherché sur le net, et ai trouvé deux blogs qui ont fait un système identique Tengu en suisse et Godefroy en France. Dans la suite de l’article, les sources LaTeX.… ≫
At Le Loop hackerspace, we often get broken, old or unwanted weird devices. Then recently we were given two Led Matrix displays with a technology from the 80s. First one was a one line with red led display and the second one was a green multiline display. So, here is a little story on how I managed to pwn them.… ≫

I just released my Master’s work done during my Internship at Bearstech. The code has been released under GPLv3 on my github. The goal of that project is to build some kind of distributed middleware that stores and share data across different nodes (whatever they are) indexed by metadata. For instructions on installing and using it, please read the wiki page.… ≫
Back in high school, I had the luck to get some experience and learn many things about stage lightnings. But, as I was already computer-litterate at that time I was amazed to discover that at the ethernet era, the protocol used for controlling lights was still DMX-512 based on RS485 serial line over a 3 points XLR. Because the DMX network configuration is a daisy chain, it looked to me a lot like BNC-based 10 base-T computer networks… with cable length, line terminals… being one’s worst nightmare.… ≫
