Disco Noise
Disco Noise is a fun little noise synth that I created during the development of the Disco Distortion pedal. Creating a boost circuit to amplify the awful sounds coming from the “automatic” RGB LEDs when they do their little light show, and then running this signal through a 4040 to get lower octaves of these sounds. So with three copies of this circuit in the same box you can now harmonize with LED noise!
Disco Noise User Guide
This device runs on a single 9V battery (not included) or 9VDC power (2.1mm jack: center-negative).
Info:
The Disco Noise is a noise synthesizer where all the sounds are created by RGB LEDs. Which is a great sounding mix of peculiar and awful! The LEDs are run through 4040 CMOS chips which lets you divide down the signal and create octaves of madness.
Seperated into three individual “voices” with divider and volume knob. All summed up to a single output.
Controls:
Black Button: ON/OFF.
White Button: Wild mode (fast LED) ON/OFF.
Green Knobs: Rotary Switches to divide down the LED synthesized signal. Goes from screamy noise, to bass notes, to just low clicky silliness.
Black Knobs: Individual volume knobs for the three LED noise voices.
Enjoy!
