I have had a cooler laying in my shop for a while, and the other day, I thought to myself, that would make a great incubator. Heres the great part. The cooler is a coleman 5640 Thermoelectric cooler.. So, why is this so great? Because the cooler can heat, or cool itself when plugged into a 12 volt circut. It also already has circulating fans. The only part that is missing to make it an incubator, is a thermostat to control the heat. I cleaned up the cooler the best I could, and gave it a test run to see if it even worked anymore. To power it, I robbed a power supply out of an old computer I had laying around. When I first plugged it in, It was in cool mode.. Not what I wanted. The fix to get it to heat instead of cool is simple though. I had to reverse the power leads. Now that I got it to heat, the next step was to see what temperature it would acheive. After 2 hours of running, it was up to 120f. Too hot for a bator, but a VERY simple fix. Just install an adjustable stat. On my incubator that I am currently running, I used the thermostat out of a fish tank heater. I have several more laying around, so this will be the stat of choice in this incubator as well. Heres some pics of the basic cooler, and the heating system that coleman was generous to include with this model cooler:

The inside dimensions of the cooler are approx 1 foot deep, two feet tall, and 1 foot wide. It will be a pretty small incubator, but I am guessing there is enough room to hold 50 or so eggs. This is a project I am just starting, and these are the steps that will be required to complete it.:
1: Cut out front door on cooler, and install a window
2: Install stat, and possibly a light
3: Make an egg turner that will fit in the cooler
4: TEST

So, these four steps should take very little time. This has to be the easiest DIY cooler idea I have thought up, or seen for that matter. Fan forced, and almost all the parts are already in place from the factory.

My main reason for using this cooler, and its already in place heating system, is because it is 12 volts. Where I live, our power from the utility company likes to go out often. With this cooler incubator If the power goes out, all I have to do is take it out to the car, and plug it in the cig lighter, and viola, back in business.

I will take pictures of the build process, and update this thread as I make progress.

So After the last post, I cut out the door, and screwed, and glued a peice of acrylic to cover the opening. I used silicone glue. :

I then Re-installed the door on the cooler:

Next, I took apart the aquarium heater by removing one screw on the bottom of the black housing:

Next, I cut off the heating element - This can be discarded, and will not be used:

I then cut a length of 1" PVC pipe, to protect the thermostat. It is long enough that the circut board DOES NOT stick out when you slide the stat into it:

Then I drilled a bunch of 1/4" holes in the pvc pipe to allow air to flow to the stat:

I drilled a 1" hole in the cooler to pass the stat through. I drilled mine in the top, close to where the heat is generated in the cooler to help prevent temperature overshoots:

I then installed the thermostat into the PVC housing I made in the previous steps:

Wired the thermostat up by taking the wires going to the "element" off of the terminal strip and hooking to the wires that came off the bottom of the stat, and putting the feed wires to the stat where the element wires were on the terminal strip:

I drilled a hole in the top cover so the stat dial sticks out to adjust it:

I just plugged it in, and in a couple hours, I will post the results of operation so far. The next thing I will be doing once I get the temperature dialed in, will be installing a 12v light, and a switch for the light so I can see in the bator. Then I will begin construction on the egg turner.

Thanks. It took about 1 hour to get it to this point. Oh yeah, Its up to 98f now. Once it levels out, I will work on humidity. The silicone smell at the moment is overwhelming when you open the door.. That should be gone by tomorrow. I have 10 more eggs ready to incubate, so I think I will put them in tomorrow or saturday. I am going to have more chicks than I know what to do with! lol.. I figure if a person has 3 bators, and you load one a week, you will have chicks hatch every week.. That could be fun. I figure I will end up keeping around 15 hens total, and any more I have will get sold on CL. They are all Barred Rock.. After the coon attack though, I only have 3 hens laying.

Hi Jason!

I don't understand what it is that you are using for a "heating element" since you discarded the one connected to the thermostat.

I also didn't quite follow the wiring description you gave for the thermostat. My mind missed something somewhere.

What did I miss?

I was wondering the same thing... I also started getting really nervous when scanned the pictures real quick. I saw that aquarium heater and my first thought was that glass will shatter if it's not submerged (been there done that) Then I saw the PVC and started to panic that it would melt.

Now that I see you discarded the element I feel better.

And now that I went back and read that you are using the cooler/heaters built in heater system, this post I just wrote is totally useless.

Greatjob. I think I may have one of those cooler/heaters (but smaller) hidden away in my garage. Hmmm maybe a project for next weekend.

Triggerjay, Which Springfield are you in. I may have a need for a few Barred Rocks as it's beginning to seem I got a few more BR roos than I wanted.
