Arduino head tracking solution for BCI application

Hi all, if you are looking for a low cost Arduino headtracking/AHRS
solution for your project, you may find my post helpful. I use an Arduino
board with a 11$ 9 DoF sensor board on ebay to create a head tracking
application base on the open source code for Sparkfun 70$ Razor sensor.
