Solar Joule Thief HEWEY Boxed
This is the ‘Automatic Solar Joule Thief’—-“Hewey”–boxed. The device is a simple Joule Thief LED/charger circuit with an automatic solar charger attached. It uses super capacitors instead of batteries to store the energy. “Hewey” gathers energy from the sun for a few hour a day into a large super capacitor then waits. When it gets dark he then turns on his white LED lights. While the white LEDs are on, energy not used is being recovered into a smaller capacitor. A switch allows for swapping of the capacitors.
