workshop physical computing
build your own ribbon controller!
As a follow up to the physical computing workshop, Johannes Taelman made a nice tutorial on making your own ribbon controller.
Ribbon controllers are (multi) touch sensitive strips that you can connect to your microcontroller (e.g. arduino.cc) for your own audiovisual calamities.
Don't be afraid of the diagrams and formula's, it's quite easy to make.
