Title: Solar battery charger
Post by: tattoosteve99 on March 31, 2012, 09:19:18 PM: Upon finishing the project I figure I would post here instead of the flashlight thread.

It is a charger for iPhone, lion batteries (4.2 volt) and other USB devices. Working on it was a learning experience and I enjoyed learning as I went. Next I will add the solar panels and figure out a charging circuit for nicads and other AA,AAA batteries. Also this device will charge using 8-30 volts dc from any jack. It also has a battery backup for dark times although it will not fully charge a device or battery.

Heh. We should have a section here dedicated to projects that use breadboards :)

True homebrew.
