My experience with electric shock pretty much mirrors Russells. This sort o= f thing is not to be encouraged. In my view building something such as that= 'tingler' box is irresponsible in the extreme. Bad enough to get zapped accidently.

Edison used DC distribution - and publicly made capital out of how much saf= er than AC he claimed it to be . Too many of his line staff found out how fatally dangerous it could be :-(. Avoiding electric shock generally is a good idea [tm].. I've had numerous 230 VAC shocks - nothing at the full "holding on with bot= h hands" level, but enough to be increasingly careful with age. I've had DC shocks (fewer) - including a 1200V DC one in my early teens tha= t could have been fatal but only gave me a nasty wack. And a very few RF burns for completeness. Some people only manage the one that kills them.
