Im asking this question as last year i built a gaming rig, which has 6 x 125mm fans and 4 temperature probes controlled by a very neat fan controller and temp sensors.

The unit runs on a 12 volt rail from the PSU (power supply unit) through a standard molex plug.

Im guessing a Jaycar speed controller works in the same way?

if it would work, you could have a damn fancy dew heater controller for under $50, and for a few more dollars a touch screen model
I don't have a lot of expierence with electronics but it would have to work in the same way if used on dew heater straps. The added bonus being that you can have a probe for each giving the current temperature.

It is a pity they do not provide a photo of the board.


Re: Measured temp of the resistor dew strap....

I took multiple readings of the resistor dew strap that I recently made and at maximum it is averaging just under 60 deg C. I don't think I would ever need to run it at maximum. I will need add some extra thermal insulation to the outer surface to direct the heat more efficiently into the areas it is meant for.
