In this video, a Cyndustries Photon module is used to control a modular synthesizer with light:
The Photon Interface module comes with a black metal Littlelite brand high-intensity gooseneck lamp, a rheostat dimmer, heavy duty right-angle 4-pin panel connectors, and an independent 12 Volt DC power transformer for system lighting right where you need it.
The lower half of the module features a sensitive photocell with its own dedicated voltage processor which can be used as a performance controller when your hand passes between photocell and lamp.
The voltage processor has an adjustable attenuator and comparator and offers both positive and inverted outputs. Rushing the photocell suddenly with your hand will also generate a Gate Output for triggering different things, and you can switch between an external signal input or an adjustable internal voltage supply simply with the pull of a knob.
