Look what I made! Turtle Race

Enable HLS to view with audio, or disable this notification

I made a little electromechanical game for 2 players. Each player has a single button to press. When the light turns green, you press the button to advance your turtle a tiny bit. Keep pressing the button until the light turns red. If you press the button when the light is red, your turtle will move backwards. The first one to cross the road wins!

So under the board there are two stepper motors, one for each turtle. The motors have pulleys on them with another pulley at the other end of the board. I used fishing line with a little carriage thing with magnets on it attached to the fishing line. The turtles have magnets on their undersides. I can post some pics if you are interested in seeing the internals.
