Well heck, just let me muck around and be happy for a minute or two, eh?
What the hell is a voltage divider? I don't have specs on either end of
this mess and if I did, they'd likely be off by a bit because of the old
and corroded factor. Sort of like the basic specs on my brain. :) I'll
continue with my little experiment tonight, after all, I have a fire
extinguisher.
