Drawdio is an electronic pencil that lets you create music as you draw. It’s a basic music synthesizer that leverages the conductive properties of the pencil lead and can generate musical tones based on its resistance.
It’s a lot of fun to draw a piano and be able to play the notes, once you complete the circuit. It runs off a single AA battery, so no need to source a strange cell size. And if you already know how to solder, go ahead and grab this kit anyway. It’s that fun!
Verdict: 9 out of 10
Fun to build, fun to draw
