We have no solar cells, which would have been cool, but the battery idea is
useful. We have a lot of mini-motors, so maybe one of those attached to a
bank...

No polarity switches either, but I'm going to put them on the next Pitsco order.
Thanks for the suggestions Mr. Davis. I hope the team will be able to make use
of them. As you said, 200 is a lot of caps!
