Patrick.

I read your old thread a few times a while ago and being a retired advanced electronics teacher I might be one of the few who understands it. You did a good job with the circuitry and finding the appropriate parts. In my case, the pushers will be more cosmetic because I don't need them for cooling. They will work but independent of the puller and only when I turn them on. Thanks for the suggestion though. On a lighter note, I am expecting good things to come from the bathroom stall brackets.
