So I went to Home Depot today and picked up all the stuff I needed to build a bator. I stoped at my dad's on the way home because he said he had a styrofoam cooler I could have. First, dad's cooler is a regular cooler - plastic on the inside and outside, with styrofoam in the middle. No biggie, just a little more difficult to drill vent holes in it. So I'm building the bator... I set up my hardware cloth, I put in a cake pan with some water, I set up a digital thermometer/hydrometer, drill some vent holes. Then I start fiddling with the light and thermostat. I either got the wrong kind of light fixture or the wrong kind of thermostat. I have tried EVERY possible wire connection and combination and NOTHING is working. For now, I have a bulb in there and I'm checking every 20 minutes or so to see how the temp is behaving. I got one of those hot water tank thermostats, it's looks like the one Miss Prissy (sp?) has in her post. The light I have is a cord with a plug on one end and a bulb socket on the other with those clips that will hold it in place if I were to put it through a hole of sorts. I went ahead and put some of today's eggs in there just to see what happens, but so far, I'm finding this a bit aggravating. It would really make me feel better if the thermostat was working... maybe I'll call my FIL tomorrow and see if he can offer some electrical input.
