There are several incubators on instructables... why create yet another? Because choice is good, and I liked something from each of the others, not one in particular.
Those last two bullet items mean to write some software, which is what I do for a living. I spent about a day to get this done. I also had my 9 year old and my wife helping. Turned into a great family project!
Here are some of the instructables that I got idea's from:
UPDATE: So I did not have enough fresh air entering the incubator. Because of this my eggs did not hatch. If you follow this build, just make sure you add more ventilation than I did.
Using the hole saw we cut a viewing hole in the top of the container. Using a utility knife I cut a piece of plexiglass a little bigger than the viewing hole. Then traced the plexiglass onto the container and used the utility knife to trip a bit more of the container so the window would sit flush. Duct taped plexiglass into position.
For the egg holder, I used the scrap pieces of wood to make a rectangle tray about the same size as the opening of the foam container. Then stapled the screen to the bottom of the frame. Finally put some slats to be able to divide up the eggs.
I didn't want the egg holder to be on the bottom, but instead suspended. In order to do this, since the container is tapered on the inside, I carved into the styrofoam a tray holder with the utility knife and the rasp on the corners and two long edges.
