This always looked neat to me but unfortunately I am not very handy. It was my brothers project. He moved out and left some items behind. This was one is them. My brother isn't too crazy handyman so this can't be hard at all to finish up. Basically the piece you get is the back of a 360 controller with the tilt board installed. 2 small Holes are cut to turn tilt on and off.
All you need to do is win the auction, get the item and solder a couple wires to your existing controller. Make this the back to your existing controller and you're good to go! :)
