Drawdio Music Pencil Lets You Doodle Electronic Sounds

Feeling musically inclined, but haven’t the time or knowledge to write sheet music? Now you can produce your own sonic creations simply by doodling on a piece of paper.
Designed by Adafruit (in collaboration with Jay Silver), Drawdio is an analog synthesizer circuit that straps to any soft-leaded pencil, and lets you crank out electronic sounds while you sketch.
