Over at NYC Resistor, we put together a little team to enter the Jello Mold Competition at Gowanus Studio Space. The team members were me, Astrida Valigorsky, Mimi Hui, and Catarina Mota. After a false start or two, we ended up making a working toy piano out of jello (and some electronics). The Resistor JelTone tied for the Creativity Prize, and you can see it in the videos below.

That same weekend, I took some of my homemade instruments, including the 8-bit violin and a second JelTone (built in haste at the last possible minute), to the Solid Sound Music Festival for the CDM/Moog Handmade Lounge. After all my jello melted, on the second day of the festival I rebuilt the JelTone with fruit salad instead, and here it is:

You can download construction plans and arduino code for the jeltone on thingiverse.

The jeltone was a finalist at the 2012 Guthman Musical Instrument competition.
