The Resistor JelTone: an edible toy piano

Posted on Monday, September 5th, 2011 in Arduino by NicholasCLewis

A group from  NYC Resistor (Ranjit Bhatnagar, Astrida ValigorskyMimi Hui and Catarina Mota) made an edible toy piano, called The Resistor JelTone, for the Jello Mold Competition.

As part of our experiments we realized that jello and fruit, which contain a lot of water, are conductive. Embedded in each jello/fruit key is a sterling silver pin (food safe) connected to an Arduino microcontroller underneath the piano’s base. Below the piano’s case is another sterling silver pin. With this setup, the JelTone can either be played with a metal utensil connected to the Arduino, gloves enhanced with conductive thread, or bare hands by touching both a key and the piano’s case.

This project is open source with all the files hosted on Thingiverse.  It could be interesting to see other applications for using the resistance in food to control electronics projects.
