Tried killing myself this morning, very stupid
-
This morning I got into work about 2 hours before everyone else. The company I work for designs "appliances" for the medical industry. We help to save lives, but I'd need a non-disclosure form signed from everyone here before I could say more. So I get into work and I am planning on mounting a computer power supply to a piece of nylon board along with a controller circuit and an assembled product. Someone could take this with and demo it. The assembly uses 12 VDC, so a CPU supply is perfect. I solder a large amount of wires, add fuses, switches, relays. Now in order to get the power supply to work outside of a computer, I've got to short pin 14 to ground. So I do this. Everything is ready. My left hand is lying on the supply, the cover is off, so my hand is on top of the internals. And... I insert the power supply cord to the back of the supply. The switch was in the on position. If you have never felt AC voltage flowing though your body, I DO NOT RECOMMEND IT. I jump back and I am not fried, my hair is not on fire. My heart is going about 300 mph and my left pointer finger is a little sensitive. I say to myself, "You lucky son of a ....." The secretary walks through the door, she smiles and says good morning. I reply back in same fashion as she sips her coffee and walks past.
I'd suggest a career change - programmer maybe - anything that doesn't involve actual knowledge and usage of hardware. Stay away from moving electrons; they bite. If you must dabble where no sane layman would play, wear gloves. I work with circuits that operate at 120V to 69kV every day, and although OSHA would shit about it, I can tell you that plain leather gloves - dry - are sufficient to protect you from up to 240 volts. Above that level you need to use rubber gloves rated for the voltage you're playing with. I have two sets - 600V and 30kV. If you plan to continue sticking your fingers in places God never intended them to be, I'd recommend buying some appropriate protective gear. It's not cheap, but what's your life worth? Have fun, and please do stay alive, if you can. If you ever want a cheap thrill, try holding on to a telephone circuit and calling it at the same time. The ring signal is 120Vac and it feels every bit as good as line current, but it's current limited so the damage done is less than lethal.:)

I was fitting a light switch in my house a long time back, I asked a friend to throw the mains switch off, he said OK, so I gripped live and neutral to pull the wires down the wall so I could access them, as soon I did that my eyes fuzzed over and I was thrown outside the front door of my house. Apparently it was an old main consumer unit (mains board) and he'd missed 1 switch that contact the lighting circuit. Needles to say the next I had the mains board replaced for a upto date one.

I have, but with 220 V, not 110 you get in the US. Quite scary. Worse, I was on a ladder and I almost fell off. :~

Is it? A supply that is designed to pump out several amps, as in, probably 10 or 20 or more? Is what you're powering requiring that much juice? And what about all the other voltages coming off a CPU supply? I don't know about you, but "perfect" means the right tool, in this case, something that closely matches the power requirements of the equipment you're powering, not something juryrigged that's probably complete overkill. Well, that's my 2c. Marc

Depends on the quality of the PSU. A cheapo will generally react badly to a highly unbalanced load and have significant voltage shifts as a result, a better quality one won't care.

He'll be able to light dead flourescent bulbs simply by walking past them, I'm sure. I do that all the time, and I've only licked a 9 volt battery once in my life.
