Machine converts light from microfiche reader to music on a Casio keyboard

Andrew sez, "IEEE Spectrum reporter Josh Romero did a short video piece about the microfiche-to-MIDI machine that I showed at the Bay Area Maker Faire. The machine converts light from a microfiche machine into MIDI signals, which are then played through an old Casio keyboard. The machine is used by the band Microfiche in a few of their songs."
