Dollar bill ghetto blaster is a dollar bill with a potentiometer made of velostat, a transistor and a coil speaker made out of conductive fabric with a magnet on the backside of the bill. The circuit is powered by a coin cell battery.
This project was made with JC Karich during a workshop “a kit of no parts” lead by Hannah Perner-Wilson at the Media Lab MIT of Boston.

Thank to HANNAH……
