Ok here are a couple pics of the modifications that I made to my LG.
The fan I used is actually the fan out of a computer power supply rather than the one that cools your processor. I used some little plastic spacers to pull the fan out about a half and inch from the styrofoam, and like I said earlier, the fan is pointed so that it blows up toward the styrofoam and away from the eggs.
The modification that I didn't mention earlier is the addition of a larger knob on the temperature adjustment. It made it much easier to make smaller adjustments. I also took a piece of thin hard plastic to make the metered gauge around it.
Nice pics. I've been thinking of doing this, as I have 10 computers in my garage I bought for a buck at a city auction. I just bought my LG at an auction this weekend.
Question: I see you ran the wires from the fan back down toward the bottom of the circuit board, but the manner and area of connection are hidden on the pics. Can you tell me where the connection to the power is?
Another picture showing that would be great.
I didn't actually tie into the heater unit power. My fan was a different voltage so I used an old ac adapter that was the right voltage for the fan. I just cut off the end and hard wired it to the fan. I ran the cord through the heater box just to keep it out of the way. My bator is full of eggs at the moment so a pic might take a week or so to get.
