Felix Bänteli and his friends from the fabulous kulturbüro in luzern  made a very cool, solar powered, wristwatch-like-synthie. I redesigned their version. it has now a nice product-like finish without loosing it’s geek-factor.

It has a tiny solar panel,  two buttens for beat and melody, a piezo (simple loudspeeker) and a minijack(headphone) out… and it is controlled by a AVR ATtiny13.

Make your own! the hole documentation on

And of course, its made completely in the FabLab Luzern
