    I have been asked through the PM here on BackYard Chickens Forum to build a incubator step by step with measurements and pictures. So here goes.

    1. You will need to keep the cost down, it wouldn't take long to
    exceed the cost of a store bought "bator".
    2. Use recycled parts whenever possible.
    3. Have fun doing it.

    We will need to gather the parts before we build. I had an old Power supply that I was going to throw out. So I will start here. First remove the power supply from the computer. and take the four screws out of the power supply case. They should be located on top.

    Remove the top and locate the fan on the inside.

    Then remove the four screws that hold the fan in the case.

    You will need to cut the wires as far away from the fan as possible. You should end up with this.

    That should be it for the fan except for the wiring of the fan. I will cover that in the next post as well as the rest of the parts needed.

    I could use some advice on the fans. I bought a fan with power supply already attached....but it was way to powerful. I returned it, and bought a smaller fan, and it has 3, not two, wires. What do I buy for a power supply (it's supposed to be a 12V)? (I cannot find specs, am going back to the website....geek.com.....to find them.)

    Advice?

    One wire will probably be a ground. If you want to try and skin back the wires and just hook 2 at a time up to the wall wort. I believe it will work. You won't hurt anything the output from the transformer is only 12vovlts.

    Thanks! It worked. I'm just so paranoid about burning the house down (and obviously lack any knowledge of wiring/electricity.) This just might come together today.

    here is the picture of the styrofoam ice chest I would to use.

    Quote:Computer fan info:

    Almost all computer fans run will at 1-12 volts; the more volts, the faster (and louder) the fan gets. Do not exceed 12 volts.

    The power wires: The red wire is the + (positive) the black is the - (negative). If there is a third wire present, (usually yellow) that is the RPM feedback wire. On newer computers, the motherboard uses the RPM feedback in coordinance with the CPU/motherboard temperature monitor. When the CPU/motherboard gets hot, the motherboard applies higher voltage to the fan making it run faster thus cooling the system. So when using in an incubator setup, you don't need to connect the yellow wire. Tie it back or cut it off.

    You should be able to use any AC/DC converter that is rated at 12 volts or less. Less voltage, less speed, less air movement. Considering the small size of the incubator, I'd probably go with a 5 or 6 volt. The fan will last longer, and we don't need to circulate the air around that fast anyway.

    I'm trying to do the same thing...
    hook up a 12 v pc case fan to my still air styro little giant.

    I have tried two power supplies (from the thrift stores, I suppose phone chargers or something) with it, here's what happened. And I followed the directions to hook the red fan wire to the power supply wire that is "dotted" with white lines, the black to the other and didn't do anything with the third (in my case, blue) wire.

    Ok so the first was 12 volts output, 1500 mA (as I was advised by my computer geek friend to use greater than 750 to keep from over heating the fan). When I plugged it in, that made a bad hot plastic smell and the fan didn't move. Unhooked it from that one and tried another power supply that was 12 volts out and 750 mA--that one made the fan smoke. I wonder if I killed the fan.

    Any suggestions out there?

    Ok I'm answering my own question. I showed all of the above to my computer geek son in law. The fan I have is 12 volts so that was right. He said it is rated 400ma or .4amps I think? I fried my fan.

    Back to the old drawing board in the morning!
