From the project

Cacophonator KiCad project

This repository contains the KiCad project of a try at recreating an instance of the cacophonator by Arthur Harrison.

- Using THT (Through-hole) components - Designed for JSL 166x116x70mm Box

- Added a potentiometer to control the output amplitude (volume) - Should be a logaritmic (log) potentiometer - Added DC Input jack with diodes for multiple, concurrent, power sources - Battery (9V) - DC IN (9 or 12V))
