Yup, you are correct; I am one year away from high school.  And that sounds
awfully bad...  Thank you for your advice, and I will go through the safety

Just a comment, I've gotten electrocuted a bunch of times (I'm lucky to
still be standing) and had no problems.  The recent ones was when I was
modifying a ATX powersupply as a bench top type for use in my projects; I
got shocked two times by those large heat sinks while taking live
measurements (luckily my dad was there).  The rest were in my childhood.

Ray, I want to word an exterme set of cautions for you. I don't know how old
you are, but I've gotten the impression you are in high-school

I think I'm rather lucky to have gotten away with such experiments about the
same age, having gotten myself across a 450V supply in my American Bosch
radio. Really, it's a whole different thing to work with HV compared to
digital. Don't do it without supervision and training. Please. I speak as
one who had a hole drilled in his finger from the experience. Even if you
think you know what you are doing, it can get you.
