Beat-IR

This page has a simple goal: to track down the absolute simplest circuit schematics for room-wide sharing of a musical tempo.

(One could imagine more elaborate uses).

This technique was ideated by Sid, at Noisebridge, who suggested blinking a musical tempo to a roomful of analog and digital instruments, by bathing the room in a blinking infrared light.

(One could imagine communicating more complex musical messages, but that's beyond the range of this particular article.

Goal: To simply and cheaply communicate, via IR, to Midi synths, analog synths, CMOS synths, and computer synths.

Schematics:

IR-to-MIDI

IR-to-CV

IR-to-CMOS

IR-to-USB
