How can you build a device to draw for you?
How To Make It
Let's start with the circuit. Power + DC motor (Tip: use the motor mate)
Tuck battery under DC motor and attach with rubber band.
Rubber band together the battery cable and insert your charcoal or marker. What other tools can you draw with?
Place the motor mate onto the DC motor
Attach the LEGO axle and wheel to the motor mate. Don't have an axle or a wheel? Make one!
Put it on paper, turn it on and let it draw!
