Here’s a first: an XBox controller hack that lets you control it with another controller (PSP, Nintendo DS, etc.). The game interface uses relays to activate solenoids, which than press the buttons. Video clip after the jump.
How this works: The XBOX buttons are physically pressed by arms (stiff wire) attached to servos that are controlled by a Basic Stamp 2. The BS2 is controlled by a gumstix over a serial port. The gumstix talks udp and accepts commands. So if you want to control an xbox, you basically have to talk a simple udp protocol to the gumstix.
