Tom has written up how he built his automated chicken feeder. First he constructed a large funnel inside the chicken coop. This feeds into a hardwood block where the auger is located. He had originally tried using a drill bit run by a slow moving copier motor, but it couldn’t slip so it would jam occasionally. The bit was replaced with a coil of stiff wire. It didn’t have as fast a feed rate so it needed to be run for a longer time period. The final piece is modifying an outlet timer so it will drive the motor directly using battery power. The power circuit has low enough requirements that it could eventually be driven by a solar panel.
