This bator does work-I've hatched and incubated in it. It's made from pine interior cabin siding and a plexiglass full-view window. Any technical details, you may have to wait till my DH can answer them. I helped him, but he's the one who does wiring at our house, LOL. View Hole for Video Camera linked to TV: Originally two courses of siding high, it was too hard to keep the temps steady so DH cut it down: Had to put a sheet metal guard in front of the bulb or it would get way too hot when the turner was tilted toward it.
