I was looking at pwm as that seemed to be the norm but if the frequency is low, just the high and low or pulsout with a variable pause in between is easy enough.
My objective is to keep heating to a minimum to conserve power when running on a car battery, hence bob's idea of calculating dew point and regulating heat.

I lied, 4 components

The FET is a MTP3055V, good for 12 amps !!. But any digital N channel FET would do.
Dew point calculation is very clever to save power, would also need an ambient temp sensor. Could be easily handled by even the 08m2 and a bit of code.
Bobs article is a work of art though, a whole different ball game and very comprehensive.
