[Jason] sent in his low-tech, but interesting hack to allow the use of a DDR pad with his Gameboy advance to play PacMan. He took a $15 DDR pad, gutted it and wired directly to each of the foil pads that he wanted to use as buttons. For his project, he simply wired each pad directly to the DPad buttons on his Gameboy. It’s really a pre-manufactured version of [fbz] zone switches that she built for her backpack strap wifi detector.
By the way, [matt] over at Instructables wanted me to let you guys know that they’re giving away a $15k Versalaser.
