Hi Bob....great work indeed. I was looking for inspiration and was recently reading your posts on this subject, you did last year.
I was looking at building (putting in the articles) a 4-6 channel PWM heater (I have designed & tested) and am now of the opinion that it is probably best done thru AVR (Arduino)...pretty much the same ideas you were at last year.
I sent Iceman my designs ( a week ago) for inclusion into the articles...maybe he didn't like it
. I can see why now!
Excellent work you have done!
