White noise is an element which is often included with synths in order to layer the existing sounds with a sharp burst of energy. This tiny Noise Generator is a small PCB which provides a simple solution to adding white noise or pink noise to your project, using an Electric Druid Noise2 chip.
White noise is a familar and soothing sound, often added to electronic dance floor hits to deliver impact and a sense of subconcious comfort. This PCB offers both white and pink noise using an established chip that utilises the Voss-McArtney Pink Noise Algorithm. Both elements are key features for music making devices, and a small PCB such as this can offer a simple solution to adding noise to any project.
This Noise Generator PCB runs on 12V of power and has a L7805 to regulate power to the Noise2 chip. You’ll find an interactive BOM provided by the seller here with the schematics, KiCAD files, gerbers and more also on their GitHub page. The Noise2 chips can be purchased directly from Electric Druid to fund development of future chips!
The Nosie Generator is sold by Sonosus who are based in Fife, Scotland! The English 20p coin is shown for scale and is not included.
