I needed a bigger incubator so I started working on this on Thursday. I just need to cut some plastic lighting grates down for the shelves.
It's 24"w x 48"h x 18"d, can fit 12 egg boxes and is made of solid birch. I built in a Herpstat thermostat, then I also built in a closed system, self exhausting computer power supply that powers a 3 channel, blue backlit speed controller that powers and controls a pair of interior lights, a pair of 50mm fans that blow down against the back wall, and a third 50mm fan than blows from the back toward the front of the unit. The Herpstat powers two - 3' sections of 11" flexwatt. I painted the whole thing gloss black and finished the window trim in gloss white, and gave it 8 rubber feet. I used weather strip along the inside front and a set of magnetic cabinet latches so the door snaps shut and has a tight seal.
It only took about 45 minutes to get up to 89.5° and it's been stable ever since. I can't wait to start filling it up.

Back showing the power cord and exhaust for the power supply. The 2" hole on the top leads directly to the power supply intake. All the other possible intakes were sealed to prevent air from being able to escape from the incubator.
Finished incubator (minus shelves and tubs)
I quickly drew in the egg crate shelves
