Death By Audio - Photo Modulator
Turn Light into Control
The PHOTO MODULATOR is a compact, light-sensitive controller that allows you to manipulate expression pedal-compatible effects using any light source. Shine a bright light - such as a strobe, flashlight, stage light, or even a lava lamp - onto the sensor to sweep your effect one way. Cover it in shadow, and it sweeps the other.
It works just like an expression pedal: light = toe down, dark = heel down.
Housed in a right-angle ¼” jack for an ultra-small footprint, it’s easy to aim the sensor at your desired light source. No batteries required.
Product Specs
Electrical Details
The PHOTO MODULATOR uses a cadmium-sulfide photoresistor connected between the tip and ring of the ¼” jack. Its resistance changes with light:
Bright light: <1k
Complete darkness: >1MΩ
A 47kΩ resistor connects the ring to the sleeve, mimicking the behavior of the potentiometer found in most passive expression pedals. This configuration ensures compatibility with a wide range of effects that accept standard expression pedal input.
Physical Details
Dimensions: 2.6” x 1.9” x 0.6”
Weight: 0.09 oz.
