Jason,

I would think that you would have much more respect for electricity.

Mains voltage can be lethal.  Even though YOU hardly notice it all
anymore.

There is a range of current. I believe that it is between .75 and 1.00
milliamps which will stop the heart. ( I am sure somebody on the list
can quote this better).  The voltage almost doesn't matter even a mere
12 volts will do the job and thats 1/10th standard mains voltage.

Along the same lines, I believe that there is a frequency that will also
trigger fibrillation of the heart, regardless of voltage.

There's an old joke about an apprentice watching an electrician work on
a live box.  The older guy was standing on one foot while he worked.

Well, he asked the apprentice to finish up while he went to lunch.  The
next thing you knew the apprentice was thrown halfway across the room. 
Shocked, dazed and not much worse for the wear.  He stumbled to his
feet.

" I don't understand it.  I did exactly what you did.  I stood on one
foot so as not to get shocked while working on the live circuit."


"Dummy..." the wise old electrician replied.  "Don't you know I have a
wooden leg?"

If it was a humid day, maybe even the old guy would feel a tingle.

I feel that this cavalier attitude will someday cause us all to mourn
for your demise and the reputation of Tesla Coiling.

There are a lot of youngsters on here looking for guidance.  If you want
to take chances, go right ahead, but don't publicize that anything below
say, 2500v is okay to be careless with.  Getting zapped in the garage
numerous times is not something to be proud of.  It indicates a lack of
respect with what you are dealing with.


So, to sing along with Allanis Morisette , I'll lighten up a bit.

" I got one hand in my pocket..."
