DIY Mini Synth with Capacitive Touch

Build your own capacitive touch pads using copper tape, bare conductive paint or other electrically conductive material! The code used in this project works the same with any conductive material.

3D Printing and CNC Milling

This project uses both processes to create a custom synthesizer that is simple to use. This guide will cover basics of using the Bantam Tools Desktop CNC and Eagle CAD to create PCB shields for the Circuit Playground Express.
