Power protection update

The protection method shown on the left here has served me well during these deer deterrent experiments, but I found out the hard way that it's not good enough to work with a wall wart.

Water has a way of sometimes working its way into places you don't want it, and that's bad news for one of these power transformers.

Lately I've been using medium sized plastic bags to keep our power connections dry. Make sure the opening faces downward so that any water will be forced to break the law of gravity to get up in there. The plastic bag pictured on the right is positioned under the board where the motor is mounted for some added protection.
