Sure can! Made one a few years ago that cost a total of under $15.00. It keeps temps within a degree or so if you keep the room temperature stable.

First, go bug your local pet store and talk them out of one of the large styrofoam boxes that their tropical fish come in.

Either buy an undertank heater or find someone who got suckered into buying a heat rock before they knew any better and talk them out of it.

Go to Walmart or Home Depot and buy a digital thermometer with a probe for measuring both inside and outside temps, and a plug in lamp dimmer (the ones you plug into the wall outlet and then plug your lamp into.

Put the UTH or hot rock into the fish box. Plug the dimmer into the wall outlet and plug the uth or heat rock into the dimmer.

Make or buy a wire 'shelf' to set over the uth or rock, so the egg container is not in contact with the heat.

Put the probe for the thermometer into the styrofoam box on top of the egg box. (Do not put the probe inside the egg box!) Put the cover on and adjust the dimmer up or down until you get the temperature you want. Do this a few days to a week before you expect eggs, as it takes a while the first time to get the temp right.

I've hatched beardies and leos with this, and will use it for my corn eggs when I get some.
