Back in the days of GCSE DT...
I was building a power supply from an old computer PSU. Simple stuff, just connecting the outputs to various sockets, and adding an LED or two. After finishing, I put it all back together and all was seemingly well. However, attaching the outputs to shiny things made it switch off for no apparent reason. So I took it apart again, but neglected (by purely accidental means) to remove the very powered power cord. Of course, whilst poking around inside, the inevitable happened and I got a sizeable shock. Made me arm feel all funny, it did.

"Hm. That was a bit dangerous," thought I. So I unplugged the cord, and continued poking, albeit with a numb-feeling right side.

Unfortunately, it had conveniently slipped my mind that PSUs contain a few large capacitors. They hadn't been discharged.

Yup, numb-feeling left side for the rest of the day.

Length? About a metre, and full of electrons.

heh
did something similar
but didn't get chocked
was poking around a PSU with a screwdriver without knowing about the capacitors. was removing the fan or something, I can't really remember.
Must have poked at the wrong thing.
Good thing I used an insulated screwdriver.
