A year ago I made a simple solar charger for Lithium Ion Batteries it worked well, but I was not completely satisfied. I wanted to take it to the next level.
Prototype of Solar Charging Device
I decided to use 123D Circuits to create a nice schematic as well as a custom PCB Board. I plan to order the PCBs and make a kit I could give to people interested in solar charging. I think this is a good example of how small ideas can develop into great projects as well as the development from prototype to product.
