Simple automatic chicken coop door

My solar powered, self sustaining fully automatic chicken coop. With a solar powered automatic Cadillac antenna door, Food for a month, and water that never runs out... right from the roof! More details on the door towards the end of the video. Also, I drew up a wiring diagram. The antenna motor uses a constant power and ground source, and a positive trigger. The power source can be any 12vdc supply, and the trigger must use a relay in order for the antenna to work properly. This is the way to rock it... just grab the eggs when you're hungry!
