[forrest] passed along this diy foot-pedal ‘midi’ controller. It’s a good re-use of hardware, but not a true midi controller. The pcb was gutted from an old keyboard, and the pedals were scored from a mad 60 mile tour of the local radio shacks clearance bin. Since the pedals are simple momentary on switches, it was a matter of wiring them to the controller and using a laptop to generate signals via usb midi interface. Replace the keyboard pcb with a drum controller and you’d have an interesting stand alone solution.
Just so I could enjoy some extra crow, I managed to leave one other entry out of my published list of Design Challenge entries. [Jason] sent in this MEGA32 programmer/dev board. He kept it single sided, but you’ll need a parallel port to use it.
