A Six-Pack of "Light" Beer
Al Gore and company have helped us to see that our planet is in peril. Lend a hand, make a toast, and help illuminate ways for saving Earth -- all at the same time! It's easy to do your part: recycle, refill, and recharge.

Then click the link for the instructions page. Really, this thing should work OK without the diode. It's purpose is to keep the solar panel from draining the charged battery when it is dark. It's a symmetric kind of thing, put light into the solar panel, juice comes out; dark on the panel, juice gets sucked up... but slower than charging. The annode of the diode should go to the plus side of the solar panel.
