This thing is so cute – it looks great, and sounds great too! This is the kind of device that will get a young maker hooked on synthesizers and circuit bending a young age and before you know it they’re hacking their own toys! Using standard through hole components like capacitors, pots, transistors & resistors, and the ubiquitous ATmega328 MCU, this thing looks easy to assemble and fun to play!

Source code is here on GitHub and project documentation is here on Hackster.io.

The Tiny TS is a credit card sized (100x65mm) fully open-sourced synthesizer with a 1-octave capacitive touch keyboard.
