well, i had already tried to make an incubator, and it didn't work, but i kept the thermostat, so i had the water heater thermostat already there, and then i got a free pc fan, and a 12 volt battery charger,(to attach to the fan), then i went to walmart and got a plugin light socket, if you refer back to the picture, you will see that i use a 6 foot extension cord that has been superglued to the wall of the incubator, and plugged into the extension cord is the plug-in light socket, with the light bulb in it, and then i bought the plastic cooler at a swap meet for 5 dollars, and had the window pane for the lid of the incubator, and i had the hardware cloth already handy, and i had to buy pvc pipe for the egg turner and it was really easy to make and you can find on here how to make it, in the (Home made Incubator) section of BYC, and i had to get screws to screw the hardware cloth to the bottom of the egg turner, so that when i put the egg cartons on the egg turner, the egg cartons wouldn't fall through
