Hacking a Boss FV 50 volume pedal into a MIDI controller

Completed project. The grey wire is a usb wire that plugs into your computer and pedal appears as a MIDI device. The pedal still works as a volume pedal too! The usb powers the teensy controller inside, so you need no other power. Also, since you program it over midi, you don't need to take it apart to change the program!
