Hi Dale.

Can that circuit be used for 115 AC fan control? ;)
Sometimes I feel like my brain and body are overheated
(no kidding ;) Fan is helping alot but it only has two position:
very fast blow and medium blow. I can't stay under it for long
unless I want to catch a flue. So I'm thinking to put some
controller in series to it. Implemeting PWM code would be easy,
probably some indication (like one digit 0..9 is enough)
couple buttons (increase and decrease) what else I'm missing?
