Create a Pumpkin Piano
As Halloween fades into memory and you start queueing up your Christmas tunes, why not turn your collection of pumpkins into a musical instrument? Robert Vorthman’s Pumpkin Piano is powered by a Raspberry Pi and an MPR121 chip connected to 12 touch-sensitive capacitive sensors. A dozen gourds stand in for piano keys, which, before they dry out completely, are moist enough to register a physical touch, triggering notes through a software synthesizer.
