Computer fan speed controller. any wants?

[banditpowdercoat]

OK, Update, I have the prototype working on 2 fans in my sump cabinet. Working great. Warm sensor up, fan speeds up, cool it down, fan slows down. My sump pretty much remains constant temp. These would be more benificial in automating Canopy fan's and as I do not yet have a canopy Adjust the Rheostat for the temperature. Takes a little fiddling to get temp setting right because Rheostat is not a set temp for a certain position. It's dependent on the load connected. Change any of the fan's, Add or remove some and the setting will require changing.

Heres a pic of what it will look like. 2 screws on the right for the incoming 12Vdc power supply, and the other 2 for the fan's

First batch of 10 will be at a Introductory Price of $15 ea + shipping
