Today the Arduino team officially presented the Arduino Leonardo with a video from Massimo Banzi, while it’s been a while that the board has been launched and available for sale. I really like the Arduino Leonardo and I’m already using it in some projects.. today however, I decided to make a simple little example program which shows the

While everyone is crazy about the Raspberry Pi, I’m pretty skeptical about it. Why? Well, because it’s a closed source hardware based upon a BGA microprocessor using a 6 layers PCBs. What does that mean? Well, it means that it’s really a pain in the ass to create derivative projects from it.. So, although the

The problem of missing calibration routines for the FreeIMU has been bothering me for a long time.. I was aware of many approaches to the problem but simply never been able to work on it. Thanks to the help of Andrea and Pasquale Cirillo which provided me with some calibration code based upon the “infamous” AN3192 from ST

 just got back home from a 3 weeks holidays in Portugal.. I’ve been there with my girlfriend Arianna and we traveled by car along most of the country costs, looking for waves to surf but also for nice historical places. We really had a wonderful time there, Portugal is really a great place and we

This is a simple example of some of the stuff I’ve been working on recently. This is a demonstration of the soon to be released filtering capabilities of the FreeIMU library using the FreeIMU v0.4.3 as sensor board. The sensor fusion algorithm estimates the orientation of the board and from that an estimation of the dynamic acceleration

Back in July, I ordered one of the early versions of the Olinuxino A13 board since it seemed very cool: powerful, open hardware, easily to solder and develop derivative products from it… Unfortunately, there was a minor hardware issue on the VGA output which Olimex guys promptly fixed and share the fixing procedure with us. These are some pictures I took

I’m happy to finally disclose our work on PALLA, a spherical wireless device designed for usage in videogames and computer based leisure activities. I just opened its project page where you find all the details about it, including some publications on it. The device has been presented officially at the Fun and Games 2012 conference at the

I’m working on a little project using the CC430 microcontroller (specifically a CC430F6137) from Texas Instruments.. well, I was a bit skeptical about this project because the micro is pretty hard to solder, (it’s a QFN with 64 pins).. however, some time ago I soldered it fine and only today I finally had time to run some code on

I’m working on a user friendly calibration program, since I’m completely aware that what I released some time ago using a python script and Octave is very complex to use for FreeIMU library users. So, I’m creating a new calibration software which will use Python, Numpy and its linalg component to provide an easy to
