This is a demo for Drawdio – a pencil that lets you “draw” instruments.

While creator Jay Silver compares it to a theremin, it’s closer to a Tannerin or Electro-Theremin.

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 MacGuyver 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.

DIY: Make it. Remix it. Play it.
