I designed and created a conceptual radio that utilized the action of wrapping string around pegs to control the radio. I was inspired by the meditative nature of the string, and hoped to create a mystical object with a unique interaction.
Video of working radio:
Stations are determined by the number of pegs that are touched by the string, which is conductive. The placement of the spool on one of the three metal rings turns the radio on and determines a high, medium, or low volume.
The radio is programmed using an Arduino Uno.
