Drawdio: Turn Almost Anything Into a Theremin
Loading...
Uploaded by wakeupsilver on Nov 18, 2008
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.

isn't it dangerous to use??
tingulee 1 year ago 3
No not at all. For example, if the human body is 1 M-Ohm, and if the voltage in the Drawdio circuit is 1.5V DC, then the current is 1.5uA. That is 1.5 "micro" amp or 1.5 out of a million of an amp. It is generally not considered to start to be dangerous until you get to at least 40V or more, and even then the power source must be able to supply a very high current for a significant amount of time.
