Drawdio Musical Pencil

Who would’ve thought that the humble pencil could actually be equipped with technology to produce your own symphonies (OK, maybe random music) simply by doodling on a piece of paper? Designed by Adafruit, the Drawdio analog synthesizer circuit is able to strap onto any soft-leaded pencil as it is able to produce a veritable cacophony of sounds as you put pencil to paper. Guess with enough time and practice, you will be able to carry a decent tune. If you want to compose your own tune in a more professional manner, then we’d suggest you give this $19.50 Drawdio kit a miss. Should you decide to pick it up, make sure you have some basic soldering skills in order to piece it together.
