I'm planning out a cabinet incubator build. Plan on using twin fans with 100w ceramic elements up top with water tray then a single fan/element mounted mid way down on separate thermostat to try and keep temps more even all mounted on False wall in the back. My qustion is. Has anyone ever used a linear actuator to rotate the egg trays? I've looked at how to make a simple homemade actuator and hook it to dual timer controls. Has anyone tried this?
