I came up with this question right after I wanted to take apart a microwave to see why it wasn’t heating anything before I remembered that that’s a very, VERY bad idea
Anything with large capacitors?
And people don’t realize how long they can hold power after the device has been “off”.
Edit - I forgot to add my thing! A good example of something that doesn’t sound scary is a TV, but it has large capacitors that can end you (or make a bad day).
Not a large capacitor in my case, but I took apart my old camera after it stopped working, and accidentally touched the capacitor for the flash. A memorable moment.
Word for word my answer
- Laser / LED printers can blind you and may have larger capacitors.
- Old CRT style TVs / Monitors can get you if not discharged correctly.
Is it true they can hold on to a charge for decades? I was told that but it seemed unlikely.
The coating on the inside of the tube can behave like a Leyden jar caps can accumulate charge over time even without an obvious power source.
why don’t you google that?
Do you ever find that sometimes when you intervene in to other people’s conversations to pull out some of your best absolute cracker lines like “why don’t you google that?” that people just don’t react properly at all? Like you’d expect an appropriate response like some light cheering and maybe lifting you up on their shoulders and handing you a medal and at least a couple of trophies. You know, something befitting of your incisive and insightful contributions, and instead they just kinda stop talking to you? That’s so weird huh?
Especially on a forum-style network dedicated to discussion 🙈
Don’t keep us hanging. Google it for us. (the punchline is in there)
No I expect everyone not to be lazy fucks and do some basic research on one liner facts
The original question I see as a useful conversation where a simple search would probably not give as valuable resultes.
Where simple facts like “how long does a crt tube old a charge” is a Google thing.
Desktop computer power supplies. Don’t open them.
How else am I supposed to put the magic smoke back in?
BS. Just drain capacitors. I’ve repaired a few (worthwhile ones) by replacing caps. You just need to know how. As with anything, read up.
Old CRT monitors. Particularly if they’ve been recently unplugged. There’s a cable in there my old teacher used to call “the superman cable”.
DO NOT backfeed your house’s electricity with a generator when your electricity gets shut down. You might electrocute someone working on those lines.
At least have it set up downstream of the main shut off and make sure that main is off before firing up the generator. There are devices available commercially that do that for you but they aren’t cheap and require professional installation.
I’ll expand the microwave to anything that can carry a large electrical charge without you really knowing. I had a UPC that started acting weird, that was one I just sent right back to the manufacturer. I’ll swap out batteries, but I’m not cracking open something with that much potential energy stored in it without me fully understanding everything about it - and unless I helped build the thing I do not know enough about it.
Ok firstly.
Never, work on anything that is still connected to a power supply.
This includes any stored energy. Isolate it first. Gravitational, electrical, pneumatic, hydraulic and chemical (if possible).
Don’t fuck with stored energy.
Secondly.
Learn how to test if things are live, or have any stored energy.
Thirdly.
Once you KNOW you are safe. Go hard, learn all you can.
If you’re gonna take a washing machine apart and you cut all the wires, make sure you cut the main electrical plug off as well or your dumbass son (me) will plug it in and electrocute himself with it.
and electrocute himself with it.
Um, aktschully, you shocked yourself. If you electrocuted yourself, you would be dead.
WAIT. UNLESS YOU DID DIE. DOES THAT MAKE YOU A GHOST?!!! A GHOST THAT CAN TYPE ON KEYBOARDS!!! AMAZING!!!
Yes, I am a ghost, I don’t type I just yell at it I till something happens, it’s exhausting.
You poor thing… :(
It’s not all bad tho, fuckin with people is fun.
Lol, I bet.
You are doing it the hard way. You can shrink yourself down and enter the keyboard. By flying underneath the key membranes you can short out the contacts and make the keys trigger. So I’ve heard.
You can harvest the transformers for a couple junk microwaves to make an arc welder.
If you aren’t experienced then pretty much all power supplies, battery backups, and motors should be left to someone else.
I saw someone lose a finger (later reattached) to a washing machine with a jammed tub. It was plugged in and on when they reached underneath it and yanked the belt, their sleeve ducked their hand into the drive wheel.
That said, if it fits your personality it can be both fun and satisfying to learn how to fix stuff. I try to teach anyone who’s interested and asks. Except LG washing machines, those things can fuck right off.
How did they reattach the finger to the washing machine?
Duct tape of course
super glue. Don’t get it on your eyelids, though.
This very much depends on your level of skill, experience and awareness of the dunning-kruger effect.
Since dunning-kruger isn’t valid, we’re halfway there!
This whole thread is making me anxious
Same
Microwave
Anything connected to your garage door.
That spring will fucking kill you.
kids today don’t know about the scary suction cup on crts
Air conditioner. I melted a screwdriver.
