Energy Storage Module
The Energy Module consists of a circuit board and capacitor. The circuit board converts AC electrical energy into DC energy, which is then stored in the 1.5 farad Gold-Film capacitor. Coil leads can be soldered to the two input pads and an LED can be soldered to the two drive pads. A reed switch can be soldered across the two standoffs, which when activated will allow the capacitor to power the LED.
