Whisper Synth

Friend and Cycling 74 elf Andrew Benson writes in:

I just finished sewing together an FM synthesizer that lives on a wristband and is controlled by a little brown button that serves as a knob and a pair of small pressure sensors made from conductive fabrics.  The whole thing runs off of an attiny45 chip, which is a really cheap AVR microcontroller chip that I’ve programmed with some FM synthesis routines.  In case you are curious, I uploaded some videos of the whisper synth on youtube:

It is a quiet little noise-maker, and is super fun to play with.  All of the electronic connections (except for the little hand-routed PCB) are made using conductive thread. I’m still working on some finishing touches like strengthening the weak points with embroidery and providing slightly better protection for the circuit, but the functionality is all there. Let me know what you think!
