The Tiny TS is a credit card sized (100x65mm) fully open-sourced synthesizer with a 1-octave capacitive touch keyboard. It has Audio/CV/Gate outputs and 6 synth parameter dials.

The DIY project site is found here: https://janostman.wordpress.com/the-tiny-ts-diy-touch-synthesizer/

These are the 3D STL-files for printing the casing.

There is also a PDF-file included for the panel graphics.

Fancy building it?
