Nothing memorable.

Plenty of static electricity shocks touching metal doorknobs. Where I live now it seldom gets very dry air, so it's been a while.

At one school I went to, there was this really long hallway we used to walk to get between one part of school to the other and down the middle there was this set of doors that was always left open. Some of us had discovered that while walking down that hall we'd accumulate a crazy amount of static charge and if you touched the door hinges it gave this HUGE shock. It was almost a challenge to see who could get the biggest one lol.

It was a very old building, so who knows what kind of history happened there lol. Got torn down the year after I finished at that school. Was kinda feeling nostalgic and tried to see if I can find pics of it and I actually did!






Only went to it for 2 years, had a class on the second floor of the section on the right, and another year in one of the portables.

To many times to count. I do a lot of the wiring at home and at work DIY so it is bound to happen.

One that sticks out in my mind was when I was wiring a new sub panel at work. The main panel was a hot 240v 100A circuit that was being ran to a sub panel with a 60A main. The wire had been pulled to the sub panel but nothing else had been done.

I asked the guy who had been doing the work the previous day if the power was still off at the main panel and he said yes. It was not. I arched the side of my screwdriver against the sub panel and the flash put me back about six feet and when I came to I was on the ground.

I still keep the screwdriver around as a reminder to NEVER trust the guy who is working on a job before you. Always double check.

It was a long time ago but I do remember my tongue went numb for a bit. I also felt really dumb and learned to be more careful about what I lick.
I never heard about licking any batteries. What is the sensation when you lick a 9v battery?

If you stick your tongue on both the positive and negative terminals of a 9 volt battery you get a little zap. It's how we tested those type of batteries back in the day. Try a new 9V battery so you know what one feels like compared to a depleted battery. It doesn't really hurt and it's hard to describe. It's a tingling and/or buzzing sensation. You can lick one quick like to get a feel if it's new or not. If it feels weak you can leave you tongue on it and get that slight tingling sensation. There is also a taste that goes along with the tingling.

I always just put a multimeter on DC volts and the prongs on the terminals. Never researched it, really. I know that the reading under load is considered more informative. One of my MMs (I think the Harbor Freight Ames) has a 1.5v and 9v load test for voltage. I have used that a few times. Don't know how good that is.

I find I've never felt anything from a 9 volt, I can lick it all day and it just feels like licking a fork or something. Getting my first shock as a toddler (I forgot to mention that one) may have gave me some tolerance to electricity.

Yeah, so when I was too young to even walk yet my mom was putting away the groceries and had the fridge door open, and I crawled up to the door switch that controls the light and pulled on it with my mouth, it broke, exposing the wires, and I got a shock. My mom said my face was half black, I'm guessing it probably shorted out and arced too. My mom was freaking out. They put those switches up on top now... probably because of kids like me. When I look back at stuff that happened to me I'm surprised I'm even still alive. Little kids are basically always trying to commit suicide the minute you look away for 2 minutes, and I really took that an extra mile.

A long time ago in the winter I would accidentally give my cat a static shock after petting her. She didn't like it at all and I felt bad when it happened.

Good advice.
I myself only ever trust one of these voltage tester screwdrivers and a multimeter. If the screwdriver does not lit up, i know i am save. I always test the screwdriver first with a separate present Live voltage to know for sure that it works.
Be aware that the voltage tester screwdriver works by the idea that there is a voltage difference (120VAC or 230V AC) with respect to Ground/Earth and that a human is a tiny bit conductive to Ground/Earth.

My mother is in heaven so she might be listening in / watching... Sorry mom.

But your Toddler story reminded that when i was 4 or 5. I had this electromotor but my battery was empty. And i want it to see running. So what i did was put the wires in the 220VAC outlet since the television and the lamps all worked. That was a huge zap and the fuse was blown. I did not get shocked but it scared me a lot.
My mother was quite surprised at the time because all of a sudden it was dark in the livingroom and i just was speecheless.

I saw a social media warning clip several years ago about keeping mobile chargers out of reach of toddlers. Apparently, quite a few of them have died chewing on the connector

Some of the cheaper ones don't have proper voltage isolation, so if you contact ground and one of the low voltage lines, you could potentially (no pun intended) actually end up with a 120v shock. Pretty bad design that's for sure.

My 486 mobo died from mold growth due to dust and humidity. I was trying to revive it by cleaning it and it did nothing so out of desperation, plugged naked 220V live wires into the mobo socket. One capacitor blew up and launched like a fiery projectile into the air and disappeared. I was lucky to get away unharmed.

Yeah, not a good idea. You could have popped a lot of capacitors and some IC's might explode. The epoxy package goes up in fragments. You are lucky that nothing came into your eyes.

There is usually an EMI (EMC) filter inside the charger to filter of the harmonics of the SMPS powersupply. Problem is that this filter is made of Chokes and capacitors. And the capacitors can still have some residual charge when the charger is pulled out of the power outlet. So, a shock is possible. I felt it a few times. chewing and sucking on 120V AC or 230V AC plugs is not a wise thing to do and parents should take care.

I think most of the deaths were from chewing the charging pins while the charger was live. Meaning those parents were not educated enough about electrical hazards or were just too careless to leave their toddlers unattended.

I messed around with motors and batteries some as a young teenager, built motors from scratch. Never messed with AC. Did some stuff with explosives, creating my own. Nearly had a catastrophe when a homemade gun went off by accident, missing my head by a bit. That cured me, didn't mess around with explosives after that.

I had a couple touching an oven handle....this was from childhood. Very odd it happened but it did

Then I had one gripping a spark plug wire.

Oh yes, sparkplug wires discharges, these are pretty similar to flyback transformer sparks from CRT tubes televisions.

I was working a dredging job in Tacoma. They had plugged up the jet pipes on the suction hood, picture a 3'x3' square vacuum cleaner attachment on an 8" hose, with 2" pipe around the periphery with holes in it to blast the mud loose.
I had cut windows in the 2" pipe to clear it out, and was welding those patches back in. I had wired the pieces in with tie wire and was welding with a 250 Lincoln DC. Seems straightforward?
I'm sitting in an aluminum workboat, soaking wet and bobbing in the sound.
Something like this.


All good though, right?
I am patching it back up and tossing the rod ends in the bilge. Brought my hand down with the stinger and unbeknownst to me, I had picked up a piece of that tie wire. That touched my thigh and POW in the front of the leg and out the back of the leg to that aluminum seat.
My ass was sore for a month.
