After working in my solar panel for some time now I am finished. I soldered all the pieces together, then I came to some problems. First, the on of the battery's connecting wires snapped off. Mr. Umekubo soldered that for me. Next, the wires that connected to the USB output kept snapping, so they are smaller due to my many re-solders. Besides those mistakes, the machine works fine. I designed a laser cut case and the solar panel itself is big enough to easily charge my iPad. I am excited to use this project more, and fix the few problems it still has.
