<<Can we add 'Camera Flash unit', or am I the only one. It was a
good one
too, had my arm tingling for 1/2 hour, and intermittent heart arrythmia for
a few days...>>
We make beacons (strobes) at work of the order 2.5 to 24 joules. I am
regularly discharging one of the flash caps through my fingers (ouch!). I
remember a few years ago getting a real belt when my wedding ring zapped
the
back of a board. Didn't much like wearing it again for about 2 years.
<<Then there's 'touching the live and neutral pins of a plug'. This
particular product (A professional minidisc recorder from a large
manufacturer), to conform to CE regs, had a cap across L-N, built in to the
product, and connected after the IEC socket but before the power switch,
with no discharge resistor. As a result, if you happened to switch off the
product on its power switch, then switch off and unplug the mains lead,
there was a random voltage between +340 and -340V across the L and N pins
of the plug, depending where on the mains cycle you'd unplugged it...
electrical russian roulette :-)>>
We have a Yamaha PFP100 piano that does the same. Always a belt when
packing it into it's flight case.

Jon
