content: I think this would be useful for me.Is a cap charged, is it safe?A series of resisters with each leg going parallel resisters. Perhaps an LED indicator.This would help me moving forward in diagnostics safely.I assume a multimeter would do something very similar. In that case, more training!!!!Thoughts?

content: Why not hire an underling to count the electrons in and out? Y'know with one of those clicker counters like bouncers used to use on nightclubs when I were young and all this were fields as far as the eye could see.(I'm not really sure what you are asking.)

content: I'm not sure many capacitors could really appreciate a good dominatrixYou're looking for a device to discharge capacitors? A metal probe with an insulated handle and a 100k+ resistor in series to ground should do a pretty good job, but most of the time it's best practice to include bleeder resistors in your design to discharge them safely in a few seconds after power-down, and for all but really large capacitor banks, that can be done with fairly high value resistors and minimal lost power.Something like a multimeter's low impedance mode (if it has it) can also be used to quickly discharge caps safely.

content: It only works for leather or latex capacitors. In a pinch also with rubber types. Also be aware that if it's done correctly, it can be painful.

content: One trick I really like to do with mains voltage capacitors is to use a 1M or higher resistor in series with a blue LED as a bleeder. Uses very little power and the LED stays lit for as long as tens of minutes after the circuit is powered off. Since that's a long time to wait for actually working on stuff, I made a discharge/voltage test probe using a current source in series with a LED as well as a resistor/neon bulb. If the neon is lit, the voltage is high enough to take extra precautions. The LED continues glowing until the voltage drops to about 4V or so.

content: get a power resistor and solder it between two shielded bananas and put it in a plastic tube with epoxy so you can discharge stuff with shrouded probes.Don't rely on some indicator, drain and retest.For really high voltages when you work on the circuit you should make some fixtures to guide probes to the correct spot so you don't slip easily

content: There is/was a company in Western Australia called "B & D Rolladoors".It always seemed a quite "out there" concept!Surely there must be limits to all things, beside it would probably damage the doors, to say nothing of theparticipants!
