Ooh "stupid kid" electricity story time? Yeah alright.

I as a toddler apparently had an affinity for arc welding coins by pulling out my nightlight ever so far. I also (on 220v) would jam metal objects in the German outlets.

Then as a teen I had been told that the electric mower was unplugged @ the house so I began detaching from the mower side. It was not unplugged, so my hand slipped and finished the 110 circult. That was fun.

Or that time where I was attempting to repair a camera flash with a (metal) jeweler's screwdriver. That's when I learned how a camera flash uses a huge loving capacitor to fire.

I had an ex whos parents had a house. When the lived they they wired up some deck lights with a length of romex attached to the outside of the deck, held on with wire staples. They eventually moved out and rented the house to her aunt and family. The family hooke the dogs leash to the romex and let him use it for a run and after a while it rubbed through the wire. It was raining one day and the father came home and fount his wife and kid both dead in the yard, as near as anyone figured out the kid went out to unhook the dog and was electrocuted, the mother saw her kid and went to help and suffered the same fate. the dog was fine though.

I think you can use a autotransformer to go up from 208V to 240V or down. Or 277 down to 240. But you cannot use an autotransformer to go from say 277V to 120V or 4160V to 480V because it provides no isolation like a regular two-winding transformer does.

Also here are all the AC voltage combinations I heard of:

69/120
120/240 (Edison two pole)
120/208
240/400
277/480
347/600
580/1000 (mining equip???)
2400/4160
4160/7200
7200/12.5k
13.8kV
34.5kV
69kV
138kV
345kV
500kV
1000kV (one test transmission line in Japan)

Aren't some of the lines I see with 4 conductors per phase 765kv? At least that's what I was told.



There was one near where I lived and we used to walk around under it with fluorescent tubes, and they'd light up. Also, on humid nights, the corona discharge was drat near deafening. Sounded like a million frying pans frying bacon.

E: eesh.. sorry about the artifacts in this crappy jpeg.

I was a smart enough kid to not get shocked, but...

When I was 7, I got a copy of the book Getting Started in Electronics from Radio Shack (great book for newbies, by the way - I got ANOTHER copy in the military as a "textbook" for the basic electronics course.) I decided to explore the ~world of electricity~, eventually getting to the point where I made my own variable ~0-40VDC bench power supply powered off 120VAC and cobbled together from random salvaged parts.

It was very cool. At least, very cool until I plugged it in, and it started vibrating across the bench for some reason. And for some odd reason, I had 360VAC coming out the other side according to my lovely little multimeter.

I figured out the backwards transformer pretty much immediately, but it took me quite a few years to guess that I probably hosed up the rectifier somehow on top of that. Between poo poo like that, solder fumes, and the repeated soldering iron burns, I'm probably lucky I made it to adulthood with enough smarts to even think about college. :v:

My electricity story is that my stove in my old house had a control panel (all the buttons and the display) that had plastic clips fail so it fell backwards into the housing. I decided to fix it without turning off the oven, figuring it would be 12v at most. I touched something on the panel and got loving lit up, probably by 220V. I fell backwards onto the ground and had some convulsions. Thankfully, that was no permanent damage but I scared the poo poo out of my parents, my wife, and my dog.

I unplugged the unit, zip-tied the loving panel back in place, put everything back together and never touched it again.

On Sunday I replaced the battery in my truck. Tightening down the terminal clamp on the negative terminal, I accidentally touched the back of the wrench to the positive terminal. I threw the wrench in the snow and stood there looking around for a few seconds, then decided the terminal clamp was tight enough. I had *specifically* told myself *not* to do *exactly* that, yet it happened. :downs:

My truck starts fine now.

That warning sign is probably in a lab that is normally occupied by people who can be described on paper as "Highly Qualified Personnel" though in reality there are as many idiots with advanced degrees as among the general population. Listing the exact names of the hazards on the sign that also says "don't eat here, don't use this as a desk" is a good idea.

Your average PhD student in Chemistry (or similar) is going to completely ignore anything that doesn't cause their brain to light up on certain key words. NaOH and dodecylbenzenesulfonic acid should light up the brain in that case. Also, "eat" and "desk", because people in labs ABSOLUTELY do those things in the labs and other places where you should not do that. But grad student office space is a non-priority for the Department admin, so you'll park your laptop on the bench next to the pipettors and clear out one of the flammables storage cabinets (which will be full of aqueous solutions of horribleness, but nothing flammable - that poo poo's under the fume hood) for your backpack.

I discovered that when I was taking apart an old disc film camera to see how it worked, and the capacitor's leads touched my hand, causing me to throw it across the room reflexively.

So of course I did the logical thing and built a box to connect it to one of those big 6v lantern batteries (with a power switch and a button so I could activate the flash to discharge it), ran a pair of wires to the capacitor's leads, and attached them to a pair of old extendable TV antennas duct taped to the body of a broken phone's receiver. It eventually got confiscated at school, and as far as I know is still sitting in the back of a closet somewhere, with the wires cut so nobody hurts themselves on it.

When I was like 13, me and a friend of mine took a lamp cable and stripped the cable off the copper, then plugged the cable in the wall and touched the exposed cabling together.

We blew the gently caress out of that breaker but somehow didn't kill each other. Only 110v but gently caress that scared me straight.

When I was 14 in 9th grade science class, working on some kind of dumb electric circuit light bulb exercise, my lab partner took the suicide cord and wired it up to a pair of old rusty tongs, then handed it to me with a paper towel saying "hey could you hold this for a sec." I absentmindedly grabbed it while writing in my notebook, and my arm contracted so hard that I punched myself in the chest and gave myself a lemon-sized bruise that lasted a week.

They make a pretty decent ad hoc taser if you remove the bulb and extend some leads.

Stick a fork in an outlet, wrap some copper around it, and run it intot he back yard. The problem will solve itself after that.
