I've been experimenting with an X-Box controller as a  (2.4GHz Radio controlled) slot car controller. 

I believe ESRM allows use of these controllers via Bluetooth + PC, but I'm using an Arduino with nRF24l01+ radio module in the XBox controller so it talks directly to the car. I just tweaked the firmware I use on my other controllers and loaded it on. Works great.
