The Resistor JelTone is an edible and playable toy piano created by NYC Resistor members Ranjit Bhatnagar, Astrida Valigorsky, Mimi Hui and Catarina Mota for the annual Gowanus Studio Jello Mold Competition.

As part of our investigation into the properties of Jello– we realized that both jello and fruit, are conductive. To create the Jeltone, we fabricated several flavors (tangerine, coconut, greentea, etc.) of Jello in key-shaped slabs. Each key was then perched atop a food safe sterling silver pin connected to an Arduino microcontroller (hidden conveniently underneath the piano’s lasercut acrylic base).  To complete the circuit, and play a noise, a metal utensil can be connected to the Arduino, or it can be played with gloves enhanced with conductive thread. Bare hands can also play the jeltone by touching both a key and the piano’s case at the same time. Alternately you can also make the Jeltone using slabs of  fruit.

If you’d like to make your own, you can get the project files, code and instructions from Thingiverse.

JelTones were exhibited on June 25th at the 2011 Solid Sound FestivalMass MoCA and at the Jello Mold Competition (where it was awarded the creativity prize and was both played with and devoured by the exhibit visitors).
