Let me start off by saying, thanks ebay! I just ordered a battery holder (3x AA holder, 4.5v) and a couple different sized smallish solar cells. The batteries I'm working with are calling out for something to keep them in line more than electrical tape, and the larger solar panel is a stated project goal. I hope to get everything in before the end of the month, and at which point I'll snap more photos and do a more detailed log entry.
