Thanks, but may years ago I got a shock from a 400uf capacitor charged
to 450 volts. From hand to hand. It made me tremble for MANY
minutes. I've been really careful since then.
How? There's not that much charge in a 100uf 300V capacitor.
Probably not in your specific case...but in a previous life, I was a military
corpsman on an Air Force base (among other places). There I learned that one of
the interesting things radar repaimen sometimes do is stick their fingers
between the leads of rather large capacitors. To make a long story short: In
six months, we had two folks arrive at the emergency room with 10 fingers
attached, 9 working. The 10th was usually removed fairly quickly to prevent
gangrene. Seems even a fairly low energy capacitor, given enough sweat on the
skin, can destroy most of the blood vessels in a finger.
Now come on! Every electrolytic made since 1938 has some overpressure
release vent in the rubber end plug or score marks on the aluminum
case. I've blown a few electrolytics in my time and they all just made
a mild hiss and a bad smell. Nowhere near the pyrotechnics you
suggest!
Again, didn't know the size of your capacitor, but I've still got a couple of
old Honeywell strobes in my attic that have much bigger caps. And one I saved
for parts after it exploded on my workbench and started a fire across the room
where the molten aluminum hit a pile of plastic boxes. Granted, there are
pressure relief devices built in, and they usually work...but every few million
(what...a week's global production?) or so it ain't going to work.
( except if you insert the cap leads into the AC line plug, then you do
get a bit more fun ). But we're not doing that.
Glad to hear you're not doing that on purpose.

I think I'll just closr up the case and be glad I didnt fry anything
else. C amera works fine when in normal light.
If the camera has an external flash connection (some do...most don't), you may
still be able to work in the dark.
