How a Drawdio is made?

drawdioDrawdio is a pencil that lets you draw music. 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…

Drawdio on Veroboard from Dylski on Vimeo. Click on the images for larger versions. The upper diagram in the photo below shows the track cuts that you need to made on a 29×5 piece of Veroboard. It’s an underside view – note the letters on the left and see how they correspond to the diagram beneath the circuit board. The lower diagram shows the component layout and how they wire into the tracks on the underside.
The components fitted. Note that for Q1 I used an 8050 NPN transistor and for Q2 I used a 8550 PNP transistor. Special thanks to Dave for picking out the parts I needed!
I could not source any copy foil so used the core of some mains cable…
The completed Drawdio.
