This simple device uses a few components to rectify the alternating current (AC) from the shake-a-gen, store it in a capacitor and convert it into a steady direct current (DC). The output can be used to run a low power device. It is also wired to an LED which lights as the generator is moved and also for a little while afterwards. An LED can also be wired across the generator connections so that both the AC and smoothed DC power can be observed.
