Compact solar charger / flashlight
by dkennell, published
This compact solar phone charger has a one-piece case, a 2 watt solar module, and a 2700 mAh lithium ion battery. The 3 bright white LEDs give a nice focused beam for a flashlight.
Print case and assemble electronics. Use the 10 ohm resistor for the 3 bright white LEDs in parallel and the 1.2 kohm resistor for the 3 mm indicator lights.
