Re: for Anand Dhuru

Hi Dave, thank you very much for the pointer; I found it very
informative and can certainly take some pointers from the math they
have explained.

BTW, some folks at the piclist also directed me to an app. note on the
X10 site that essentially uses a 16F877A as an X10 controller. Of
special interest was the way they had connected to the mains *without*
a transformer. I wonder if the coupling would be as effecient?

You might be surprised by my reluctance in using a transformer, but
thats basically because trasnformers available here are kind of
generic; they do not have any markings, nor brand mentioned. One just
goes by the color of the slug, and hope for the best. In my case, I've
found the one with the white slug (2nd stage IFT?) seems to work the
best.

Again, thanks.

Anand
