Project Status
5/1/10 Parts ordered
5/7/10 Some parts arrive - start assembly.
5/11/10 It works! Finished assembly except for box.
5/15 Doesn't work exactly. I can charge an old iPod, but not the iPhone 3Gs. May have to do with voltage levels on usb pins 2&3. More research is needed.
This seems like a good place to start researching.
6/16/10 Put project in a mint tin. Seems to work ok, but sometimes finicky about charging iPhone.
8/4/10 Works great!. Previous problems probably due to not charging battery up enough. I have been using it for over a month now. The battery can be charged up to 4.16 v.
This setup works best if the solar panel is actually outside, not behind a window or screen.
8/8/10 Adafruit now sells all the necessary parts for this project and has a new version of Minty Boost out.
