Instrument-a-day 28: wind up time code

Turning the click-clack of an old wind up motor into MIDI time code to control the playback of a recording.

 

Next I'll try controlling the speed of a video!

 

(Inside the box, the wind up motor has a flapping arm that interrupts a light beam. Each clack of the motor generates a MIDI SPP command which tells the computer how far / fast to move through the recording.)
