Drawdio kit – v1.1 STEM Electronic Pencil Kit

Drawdio is an electronic pencil that lets you make music while you draw! It’s great project for beginners: An easy soldering kit with instant gratification. Essentially, its a very simple musical synthesizer that uses the conductive properties of pencil graphite to create different sounds. The result is a fun toy that lets you draw musical instruments on any piece of paper.

  • Runs on a single AAA battery for many hours (even ‘nearly dead’ batteries will work)
  • Use any pencil – mechanical or plain. The kit comes with a 2B pencil, the softer the lead the better
  • Ridiculously fun for all ages
  • The electronic kit comes unassembled with all electronic components, PCB, hardware and pencil. AAA battery and tools necessary for assembly are not included. Please check the kit contents list below to see what is included. Assembly is very easy and takes less than an hour, even if you’ve never soldered before!
