useless machine

(This idea is not original to me. There is some suggestion that Marvin Minsky at MIT created the first. I went with a design that uses no processing power. A DPDT switch is wired to a power source and a motor, such that flipping the switch reverses the polarity. A second switch turns off the machine when it is in reverse and the mechanism has fully retracted into the box. I had to glue a bit of wood to the bottom of the lid of the box, because otherwise it wouldn't close on its own when the mechanism retracted.)
