1” Reusable Bicycle Inner Tube
Create a ”battery holder” by stretching a slice of innertube longways around a AA battery.
1
Press shaft of hobby motor into piece of hot glue stick. This creates a vibrating eccentric weight.
2
Make it spin! Slide wires under bands at ends if battery (= on). Disconnect to open circuit (= off).
3
Make it stand! Attach marker legs w/ sticky foam strips. You can orient cup up, down or sideways.
4
Make it wiggle! Stick motor + battery to cup w/ sticky foam. Hot glue stick will need space to spin!
5
Test to see if drawbot can stand on 3 legs and move! Adjust as necessary.
6
Make it draw! Remove marker caps & hit the dance floor. What can you adjust to make different marks?
7
Clean up is easy- apply marker caps back on and recycle your dance floor kraft paper.
