I havn't checked the full range yet, but I will and post temps. It will have a fairly large temp range. Should be able to cover all temps required

Also, the range of temps will vary slightly depending on load of fans attached to the controller.

I like the idea of temp flexibility.
I'll need to work out how to jimmy a fan or three in my tank cover, its kinda cramped. If you can put together the controller for $ what you figure, I'll take one.
Let me know when you've got a working set up.

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

All parts used are RoHS compliant

Cool, Dan - You didn't say it would come with a Laptop!

Ya know, if you put it up on Kijiji for way more than its worth, someone is liable to take it off your hands and you won't even need to feel guilty

Is the temperature sensor inside the black box, or is it external? I.E. A temperature probe for the water, warmer water speeds up the fan.

And how would a person go about ordering one of these?

What type of adapter is needed and where would you get it? 12 VDC or 12 VAC?

Thanks.
