Modular-muse is an instrument building platform that consists of hardware boards and a software library to explore new ways of creating musical instruments.  Modular-muse was developed by Jiffer Harriman during his PhD work at the ATLAS Institute.  

The Sound Clippys Board is another platform consisting of an Arduino based board that allows for simple circuits to be used to trigger and manipulate sounds.

The Modular-Muse Library for Pd makes it easy to get started with sound design in this open-source and open ended audio programming environment.
