I just finished this for a friend, and now I don't want to get rid of it... I hate building things for other people that are better than what I have... I guess that's what happens when you're not paying for it though.

I just finished it today and so far it is keeping the temps right on. It is using two Herpstats built into custom face plates. One is in non proportional mode with the temp set a little above optimum running as a backup then the other one is what you use to set your desired temp. Your heating device gets plugged into the output of the thermostat with your desired temp and that thermostat gets plugged into the output of your backup. This way if the thermostat with your desired temp fails and temps ever get too hot the backup with shut down that thermostat along with the heating device. Then once the temp drops .5 degrees below the set backup temp it will turn the other thermostat back on along with the heat. If there is still a failure and the heat goes back up it will keep repeating this cycle, this helps insure that the incubator never gets too hot. Other that the top and bottom pieces being 3/4 inch melamine the rest of the outside is 1/2 inch melamine board. It was then insulated it with 1/2 inch foam and ran channels up both sides so the top fans can suck some of the hot air from the heat coil and blow it up top. The foam was then sandwiched with 1/8 inch shower board, or dry eraser board and trimmed with 3/4 x 1/16 angled aluminum. Just thought I would share...
