How can
I make a cheaper chicken door opener with parts I can find around my
neighborhood?
Tom: Ashland, OH.
A car lock actuator is what Rob from Nifty-stuff.com
uses. He found two electric car lock actuators on ebay for 11 dollars
shipped, which is a lot cheaper than the drapery motor controller.
A junk yard might be a good place to find cheap actuators.
Edited to add:
After years of research, Mark eventually settled on this automatic chicken door.

If you're planning on
automating your coop, don't forget to pick up one of our chicken waterers. They never spill or
fill with poop, and if done right, can only need filling every few days
or weeks!
Hey WaldenEffect, I too am looking for a cheap/effective auto opener. I found the same designs you have, but getting 120v to my coop is impractical, and I want this to be seriously cheap. I'm collecting the parts to try this one out: http://www.instructables.com/id/Build-A-Motorized-Window-Blinds-Controller-For-Les/
As long as you counterbalance the gate, the motor shouldn't have to work very hard, so this batter-operated motor should have no trouble. I like the added convenience of the light detection as well. This is well beyond my tinkering experience, but it looks doable. I'll let you know how it goes. Good luck! _david
