I found this while looking for a teardown of a Wii Nunchuck remote since they're cheap and include a
3 axis accelerometer. I mentioned an interface board
the other day, but the responsiveness of the interface in this video grabbed my attention. If you like it, you should check out
this [
via] Nunchuck Arduino RF controlled robot. You can find details on that bot
here. The accelerometer itself only runs
about $10, but it's a pretty small SMD part.
