I found this cool site with lots of Wii and Atmel AVR controller hacks called Wind Meadow. There isn’t really much info on who runs it, other than some posts by ‘Chad’, but there are some great tutorials. Out of all the great hacks and projects worth looking at is definitely the ‘Wiimote Controlled Firefighting Robot’. ‘Chad’, also has a great tutorial (code included) showing you how to hookup a Wiimote to a microcontroller. If you’re wondering why there is so much interest in doing this vs just buying an accelerometer, it’s because the Wiimote costs $39 and there are lots of goodies inside including a 3 axis accelerometer which is $40 alone from most electronics sites. Anyway, check out the site when you have a chance.
