I tried hooking up the outdoor sprinkler and had a disaster. The booster board got fried when i shored the output leads. Meanwhile the Pi and sprinkler board got very hot. Something is very wrong. I shut it all down. I studied flights today to Alaska and I think I picked out some winners. We mos likely will go the day before to avoid hassles of being late for the cruise start. Dinner tonight was Lima beans and salad. Very nice.
