It's been running with the 7" pan under it for the last few hours. I really don't know how to adjust the temp yet but by playing with it a bit it is holding rock steady at 103 degrees at 45% humidity. I could only find one 7.5w bulb in town so I just have it in the "heat on" socket.
I'm surprised it is holding the temp as well as it is. It's in my body shop, on a table with the doors open. We have about a 8-10 mph breeze, and the temp was in the upper 50's when I opened the doors. We are now knocking on 80! If it can maintain itself this well with changing ambient temps just think of what it can do in a more steady room at home!!!
Incubators can be such simple devises that work wonderfully. I wonder sometimes why I think I need to add bells and whistles to everything. Oh, ya... because I am not going to be able to turn my eggs manually. I am never around the same time on any given day to baby sit. I need controls and a turner.
