After the unfortunate dismemberment of the hand on my lid-raiser coffin, I decided to change things up a bit and turn it into a MIB. Below you can see a test run showing the gear shape and slamming action. You may notice that the motor occasionally shuts off. This is due to the motion sensor hooked up to the power supply. (If you look closely, you can see me waving frantically, trying to get the sensor to activate.)

Since taking the video, I've upgraded the wall wart power supply with a PC power supply to give the wiper motor a little more muscle.
