I finished building an incubator for a guy in Missouri last night. He has a Ranco on the way so he just wanted it controlled by a rheostat instead of a Herpstat. It holds 4 egg boxes, has a small fan to circulate air, and because it uses a rheostat I added a 120v small green light to show whether the unit is on or off, and how much power the heat tape is receiving. It also has a Lexan viewing window and interior viewing lights.
