The Resistor JelTone

thingiverse

The JelTone, an edible toy piano, was created for Gowanus Studio's Jell-O Mold Competition and displayed at the Solid Sound Festival. It was a finalist in the 2012 Guthman Musical Instrument Competition. The team behind its design includes Astrida Valigorsky, Ranjit Bhatnagar, Mimi Hui, and Catarina Mota. For construction, use two 12x12 acrylic sheets in contrasting colors, a small high-impedance amplifier, food-safe wire, and an audio jack or cable. Attach the Arduino to generate 12 musical notes simultaneously using the _12tone_synth.pde source code. To play, place jello, fruit, or other conductive materials in the keyboard frame to form keys, touch the salad pile with one hand and the keyboard with another, or clip alligator clip jumpers onto forks or spoons. A logo can also be added for a retro look.
