This board came about while I was prepping to teach a workshop on how to make some e-textile sensors during a music / sound hacking class. I wanted to get the musical circuit onto the body quickly without needing to solder up a circuit nor the need to commit to a schematic. Soldering is not what I would be there to teach them and soldering takes some time to do! The breadboard would allow for components to be easily changed to effect pitch and speed of audio circuits.
Because the sensors or switches would be made of fabric and plastics, metal snaps make for a great mechanical and electrical connection between the sensors or switches and the audio circuit.
