AIGA Workshop: Draws circles within circles and a random awkward blue mark all around.
Build the circuit! Connect the Bits in the following order: Power + Branch + Slide Dimmer + DC Motor. From a free side of the Branch, attach a Wire + Vibration Motor.
Connect the circuit to a popsicle stick with the rubber bands.
Attach a plastic disk to the shaft of your DC Motor. See link below [d-shaft templates.pdf]
Set the whole circuit on top of a plastic cup and affix it with tape. The DC Motor and plastic disk should be hanging off the cup and facing downward.
Tape charcoals to the plastic disk. Make sure each charcoal is touching the drawing surface.
Attach another piece of charcoal to the vibration motor.
Make a cover for your robot, switch it on, and watch it mysteriously make marks.
