Bring back the good old days with a DIY Etch-A-Sketch dial that works on any tablet or smart phone! This instructable will teach you how to make a physical dial for your device. It is specifically designed to look and act like an Etch-A-Sketch dial but works with any app that uses dial controls. It is really easy, cheap, and most of the materials are household items you can recycle into this project.
You will need the following to make your Etch-A-Sketh dial:
1. Tin Foil
2. Scotch Brite non-scratch cleaning sponge (most any scratch resistant sponge should work)
3. A Nerf dart (with a suction cup end)
4. A thick and sturdy straw (mine is about 1mm thick with a 6mm hole, and came with a reusable water botttle)
5. A cap from a bottle (I used one from a milk carton)
2. A hot glue gun
