Great news! The results of the Ph.D admission exams are out. And I’m in! I’ll be a Ph.D student the next 3 years.. it’s gonna be fun!

Today, I’ve been once again at the Fablab Italia to assist a conference about digital fabrication in Italy. While I was there I had the opportunity to finally see their professional laser cutter in action. The guys where cutting a 1 cm thick (I think) plexiglas panel.. The precision of the process is incredible and very cool to see

I’m back to developing stuff.. And I can already show you something cool.. here is the very first FreeIMU v0.4.1 prototype, featuring MPU6050, HMC5883L, MS5611. Testing it next days.

I’ve been playing with FreeIMU v0.4 and its MPU6050 for some initial testing. I used the code that Noah Zerkin shared on a previous post (thanks Noah!) which supports 6DOM accelerometer+gyroscope on chip DMP sensor fusion and changed it slightly to output quaternion data as expected by the FreeIMU_cube Processing sketch in the FreeIMU library. Programs used for this tests are attached

If you are following my blog, you know that I’m into hand assembling of SMD/SMT components on PCB boards for prototyping or small series. So, I’m always in search of tools to make me more productive by making the job easier or faster. A month ago, I stumbled upon a China made Pick Up and Place

John Patillo, one of the very first guys in starting a “child” project based upon my FreeIMU hardware and library, just posted a comment sharing his last progresses in his own Smart Skeleton project. John, who’s a Biology and Human Anatomy & Physiology College teacher by day and an Arduino/electronics hacker by night, is working on using

LibreTooth is a side project I developed during my various human-computer interaction device prototyping. In the past, I’ve been a fan of Sparkfun’s Bluetooth Mate Gold, a breakout board for the Roving Networ’s RN-41 Class 1 bluetooth module. It’s quite superior to other cheaper Bluetooth modules you may find in China through ebay. Unfortunately, Sparkfun sells

As you may have heard, the Arduino team just released the version 1.0 of their IDE which comes with quite some changes in the programming APIs. So, I spent some time updating all my Arduino libraries to be used with Arduino 1.0. From now on, I consider previous versions of the IDE/API no more supported. So, if you are using my

It’s been a while since the announcement of the first FreeIMU v0.4 prototype built and you may be asking what I’ve been doing with it.. Well, the tests I’ve been doing so far with my v0.4 prototypes have been completely successful.. the unit works great. Unfortunately, I’ve been able to only test the 6 axis (gyro &

Thanks to myself, timecop and Alexinparis, FreeIMU v0.4 and its MPU6050 are now supported in MultiWii. At the moment, the code doesn’t use the DMP due to the lack of documentation for it. The MPU6050 I2C master features are instead used, so the magnetometer is now read directly from the MPU6050. Code available on MultiWii
