The heaters I looked at all run on 120VAC (or 240)
We can probably do as Metis suggested and drive it with a relay from the existing control board, unless that's a half fast
hack, too. Does the existing heater control have adjustable PID parameters, is it linear, or what?
Another trick is specing the wattage we need. Too low and it won't get hot enough.
Too high and it'll heat up too fast and make the control loop twitchy.
I was pondering whether someone with some social skills could engineer us a sample or two.
Or we get some more nichrome and wind our own again. THAT part of the Mk IV seemed to work, no?
