Demos: 6D-14 Induction and Capacitor Flashlight

This is a flashlight without the usual power source, a dry cell. To operate the flashlight, shake it vigorously in an up and down motion for 30 seconds. This back and forth motion passes a strong magnet through an induction coil. The energy generated by the motion is stored in a capacitor. By engaging the switch, the capacitor will discharge through the light.
