Feeling a bit nostalgic, Hack-A-Day reader Brandon has been hacking on a Nintendo Power Glove. The original Power Glove was sold by Mattel as a unique controller for the NES. It used ultrasonic sensors to determine orientation and could detect four different positions per finger. The finger’s resistance varies depending on how much it is bent, so Brandon used an LM339 comparator to determine the mouse clicks. For the actual mouse interface he used the guts of a Gyration mouse. He’s got a video of the beast in action plus links to an original Power Glove ad.
