Subject: On/Off Temperature Sensor For Fans

I\'m glad I found your site and and planning on building your temperature controller for fans in my a/v cabinet. I already have fans that change speed depending on air temperature, so what I would like the controller to do is basically just be an on/off device. Once the thermistor hits a certain temperature, I would like full voltage to be allowed, and not just a trickle to start at that starting temperature. Is there any way I can do this?

Thanks in advance!

Oh yeah, if anybody else was interested in this, I ended up building this version that simply turns fans on and off.

I got parts from that added up to less than $10!!

And here is a different one you could try as well but I did not pick-

Oh and I haven\'t yet but am planning on putting this site\'s \"temp controller\" in line after this other one I built, that way it actually turns the fan\'s power on and off AND has a variable speed controller!

Hope this info has helped somebody!
