Not entirely picaxe related, but the PWM would come from one so...
Has anyone, or does anyone just plain know, used a PWM signal to control the temperature of a peltier junction?
My radio telescope DC processor (If I ever finish it! It's in redesign number 7) needs temperature control. The cooler the better, but I can't afford liquid nitrogen or anything like that. What I'm going for here is more of stability than any increase in performance. I dont need fast dramatic temp changes, just the ability ot keep the temps of a few components at a reasonably constant level, and ovenizing is out of the question.
