That’s it for the “big stuff”, now a list of all the odds and ends you’ll need: Soldering gun: Borrow someone’s if you don’t have one, you’ll only need it to make a few connections.  You’ll need the soldering gun to attach the extension cords to both the fan, and the heat tape (if you decide to solder instead of using Flexwatt clipset clips). Egg containers: You’ll need containers in which to keep your eggs.  There are hundreds of containers out there, pick one you like as long as it has a tight sealing lid to retain humidity.  I use the shoebox Rubbermaid #2218 (11”x7”x4.25”) (which have become increasingly difficult to find at many retail locations). Extension cords: I always use 16 gauge, light duty interior-use extension cords found at any hardware or “big box” store for $2.  You’ll need two; one for the fan, one for the heat tape. Incubation medium: I use a perlite/vermiculite mix for my medium.  Both of these products can be found at any “big box” store or garden centre throughout the year for a few dollars.  Note:  When mixing the two mediums together (two parts vermiculite to one part perlite) do so in a well-ventilated room or outside and wear a face mask.  (Asbestos particles in the vermiculite, don’t want that stuff in your lungs). To mix the proper consistency, add enough warm water so that the mixture looks dry, but clumps when squeezed in your fist without dripping.  Remember: it’s easier to add water than to take it away.  Flexwatt clipsets: You’ll need one set (2) clipsets to attach an extension cord to your heat tape. Duct tape: No project is complete without some duct tape!  You’ll need it to stick your heat tape, temperature probe and extension cords to the inside and outside of your incubator. 3” wood screws:  To attach the fan housing to the ceiling of the incubator.  You’ll need 4 of them. Wire stripper: To strip the extension cord wires, exposing the copper for soldering. 1/2” drill bit: To drill holes. Now we’ll begin to assemble the items to make an incubator. The first thing we’ll need to do is to take the wine fridge out of the box and remove everything that is not necessary.  In this particular case, all of the tubing, hoses and condenser unit that are necessary for cooling the wine fridge are unnecessary for an incubator.  In addition, they account for close to half of the total weight of the unit.   NOTE:  This is a good time to let you know that the gasses contained within the condenser unit and all attached tubing is harmful to the environment and should not be released into the atmosphere.  That said, you can go to any appliance repair shop and they will, for a nominal fee, remove all that stuff and dispose of the gas safely. Be careful to make sure that the electrical cords are not cut or removed as well.  In my case, I needed the electrical to allow the internal dome light and the digital temperature display to work.  When the condenser unit has been removed, you’ll have a giant gap in the back of the unit where it all was. Your next step is to determine where you will need to drill your hole so that you can run your extension cords and wiring through the wall of the fridge.  Take your time and plan out what location is best so that you’ll only need to drill ONE hole; central to the fan, the temperature probe for your thermostat and the heat tape.  I decided that since the fan and the temperature probe will both be located at the top of the enclosure, that the hole would be best drilled near them.  (I then knew  to wire the heat tape so that the end connections were also near that hole as well).  You will need to drill straight through using the 1/2” drill bit.   When the hole is drilled, clean up the messy edges with some sandpaper (both inside the fridge and outside) so that it does not rub against and weaken the integrity of the temperature probe and extension cords. Next you will need to remove the female end of the extension cords with a snip and separate the insulated wires by scoring a line between them and pulling them apart a few inches.  Strip the two wires to expose about ½” of the copper for soldering.   Once you have done this, feed the two extension cords and the probe through the wall into the incubator.    Now that the wires are through, determine where the fan will be installed on the ceiling on the incubator.  I decided to use a longer screw and a “bushing” made from three 1” cuts of 3/8” rubber water tubing (same rubber water line used for the “Rat Rack”) so the fan is sitting off the ceiling allowing it a cushion of air all around, thus eliminating any banging and unnecessary noise the fan may make.  You will now need to solder the two exposed wires of the extension cord to the two exposed metal connectors of the fan. Once you have soldered the extension cord to the fan, plug the fan in to the wall to test whether or not it works.  Use this time to figure out the direction in which the fan is blowing (as mentioned, you want the fan to be blowing air down, into the incubator).  Attach the fan to the ceiling with the screws.  I did not have to pre-drill the holes as all the walls are plastic.  Once the fan is attached, gently pull the extra cord through the hole and use the duct tape to tape it down.   updated Feb 1, 2011
