Kyle McDonald shows at Instructables.com how to make your own cheap 3d desktop tracker.
Here’s a small video (non embeddable in my wordpress..)
You need :
- One Arduino board
- (3) 270k resistors
- (3) 10k resistors
- Solder
- Wire
- Aluminum foil
- Cardboard
It’s using capacitive touch sensing.
How cool is that ?
