Step 10Green: Solar charged batteries
Now for the green part: solar charged batteries!
I opened up one of those solar-outdoor light things and found a simple circuit and 3 AA batteries inside! The solar cells would charge the batteries during the day. I replaced the flimsy wires with stronger hook-up wire, and soldered on connectors to the terminals - now when I want to charge the turret, I just have to take the battery outside for a day and I'm set.
