The Xbox controller is the nice enormous one from the original Xbox, none of that 360 stuff.
Arduino micro is of course the E: D Hedtracker (brilliant device, can we get official support, and a 'lean' axis please?

), will be using another to rewire a nice gameport throttle I've got.
Out of interest, will there be support for other generic home-brew input devices too?
