The car moves

I did it: the car moves. It drives right across the kitchen floor, picking up speed. That said, it does not handle carpet very well (no surprise).

I can’t get a very good video of it by myself, so I’ll work on that soon. In the meantime, I’ll post a still.

I made a couple changes near the end:

  • Changed the gearing. The motor just doesn’t have enough torque to move the car with a 1:1 ratio, so I pressed some old Erector crown and pinion gears into service.
  • Added a toggle switch to turn the power on and off.

Future improvements would include a higher-voltage battery and a proper connector for it (so I don’t have to gator-clip the motor to the battery).
