I've just finished assembling a QSC MultiWii interconnect board. This is a board that The Crash Cast put out a year so ago. Its Arduino 328 based and uses various sensors, mainly the Wii Motion+ and Nunchuck boards.
Everything looks to be assembled right, no smoking or arcing. Firmware uploads just fine. The problem I'm running into is that when I have the firmware running, the console shows the quad drifting and rotating.
I have a youtube that shows this: http://www.youtube.com/watch?v=rQAkqBl2zQk
I have pictures on my Tumblr page showing the board: http://itchetiky.tumblr.com/
Thanks for your help.
