I am working on a project that is going to use a Wii balance board to act as a game controller. The WBB uses a Bluetooth chip to transmit its processed strain gauge data; does anyone know how I might hack it to make it non-bluetooth? i.e., instead of feeding the sampled and digitized data into the BT chip for transmission, it travels down a cable to a PC serial port? Is it as simple as desoldering the BT chip and soldering wires on the Tx/Rx, +5v, gnd, etc pins (or whatever configuration it uses)?
Also, does anyone have a decent schematic for one of these Wii balance boards? (can't find one on web anywhere).
