An exploration in new ways of interacting with common objects the Droplet Radio looks at how a radio can function without any visible buttons or controls. A weight sensor is used to determine the volume, which increases as rocks are placed on the radio. The tuning is controlled by a magnetic hematite stone, which is moved across the darker wood. A magnetic potentiometer reads the position of that rock and tunes to the appropriate station. The radio is made of solid wood and its underside is hollowed out. A sound bug is used in place of a traditional speaker and attached to the underside of the radio, effectively turning the entire radio into a speaker.
