Actually that must be the second thread I made of it.
I made the first one a long time ago, and it got locked. It had my own pictures from it so you could see it all put together.
Then I made the one you are looking at, later when someone asked how to do it.
I needed a larger incubator and ended up making mine out of an old winecooler....well a new wine cooler was $400 at homedepot but caught a deal on craigslist for $50. I gutted it and used the internal temp display plus my own temp/humidity displays. installed open shelves in place of glass, Reversed the upper fan and installed a low volt fan on the bottom to distribute heat Its large, stainless steel and has a tinted glass front, holds temps nice.
Heres a pic when i first brought it home that i had laying around after i gutted and tested out with an old thermostat i had laying around. Later upgrade to a proportional and added fans/shelves for accurate temp holding.
