Last month I wrote about Adafuit's Drawdio kit, an electronic pencil that lets you make music while you draw.

Imagine you could draw musical instruments on normal paper with any pencil (cheap circuit thumb-tacked on) and then play them with your finger. The Drawdio circuit-craft lets you MacGyver your everyday objects into musical instruments: paintbrushes, macaroni, trees, grandpa, even the kitchen sink...
One day I bought a "harmonium" kit at the street market in Bangalore. I hacksawed the keyboard off to make the first ever Drawdio circuit. We played with it at a local school in the slums using plants, water, our foreheads, etc. My friend told me graphite would work too. Meditating on it, I realized the Drawdio circuit should be literally attached to a pencil to "draw audio," and that's where the name came from: Draw + Audio.
