Automatic chicken door. Using a motor from a rechargeable screwdriver and a simple relay circuit. Controlled by a mains timer - mains on = door open, mains off = door closed. Full credit to user cfabe for the original design. His video and link to the circuit design can be found here: http://www.youtube.com/watch?v=tJuWQ_j_mLA
