Physical Face Following with OpenCV on Android


Here I am again, less than 2 days after my latest post… this must be the shortest delay ever between 2 consecutive posts.

 

First of all I hope you guys will approve of my choice of face to follow ! πŸ™‚ Β  The English title is “All about my mother” by AlmodΓ³var, which I’ve never actually seen, but my wife tells me it’s a really good movie… !

You people must have been wondering “what the heck was going on” and why haven’t I posted anything for the last 3 months or so… keep reading and you’ll find out more !

Electronic Anti-roll system for tractor (or how to connect IOIO to a Basic Atom


“Tractor”, what tractor… ? That’s what you must be wondering right now, as I don’t often blog about tractors… especially full scale agricultural ones…

This is a slightly different post for me, in that it’s about some help I gave to 2 guys in Germany, working on a hydraulic anti-roll system for a tractor.
Wow… I never though I would be working on “revolutionising the agriculture” as they’ve put it… πŸ™‚

Android IOIO Wii Motion Plus – Gyroscopes


First of all, the more I work with Android, the more I love it … ! It’s so cool to have both Linux and Java and everything is so open and hackable … !

Android IOIO Wii Nunchuck


I’ve already written a post about how to connect the Wii Nunchuck to the Lego NXT using LeJOS, and there is also information on my blog about how to do the same thing with an Arduino (though I can’t find it right now, so no easy link…).

It’s only fair that I explore the same thing with an Android phone and the IOIO board.

Kalman filter – simplified version


Finally… it’s been a while since I’ve started looking into filtering, and more precisely Kalman filters… since I started on my quadcopter project, to be more precise…

After reading the descriptions and formulas found here (highly recommend the short introductory pdf !) I decided I had to code my own simplified version.

WiiMote IR Camera with Lego NXT Brick – LeJOS


This previous post talks about how to connect a IR Camera from a WiiMote to an Arduino.

There’s also this one, talking about how to connect it to the .NET micro framework, FEZ Domino board (which also has hardware details on how to extract the mentionned camera and solder it on its own little board…).

It’s therefore time I wrote a quick post, on how to interface this wonderful camera with a Lego NXT Brick, programmed in Java thanks to LeJOS !

Tiger 1 BB airsoft RC Tank – V2


It’s all about the same project as here, BUT with a different technology: instead of using the FEZ Domino (.NET micro framework based) board, I’ll be using the Lego NXT controller and an Arduino board for low level interaction with the electronics.

NXT + Arduino internals
