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 connected to your garage door.
That spring will fucking kill you.
Batteries
I too was going to say microwave before reading the post body. Honestly though anything with a large capacitor, I can’t give you examples unfortunately because I study physics not electrical engineering but some of those fat fucking capacitors will fry you and they hold their charge.
Anything with large capacitors?
Word for word my answer
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.
- 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.
That is my understanding. I remember hearing stories about dudes visiting a dump or whatever, kicking through the screen of a CRT and getting zapped like fuck
Unlikely. Even the best capacitors would discharge through leakage in 5 or 10 minutes.
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?
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.
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”.
Microwave
kids today don’t know about the scary suction cup on crts
I heard once that old smoke detectors have some radioactive isotopes in them. Not sure how true or dangerous but sounds bad.
Ionization chamber smoke detectors have a tiny grain of Americium in them, which is radioactive. However, the radiation is almost entirely alpha particles which are relatively low risk as they don’t penetrate skin particularly well.
They are also still sold, though you should buy the other kind (which use light beams instead) because they’re significantly better at their jobs.
They’re low risk unless you ingest them, because then they’re hitting internal organs directly.
Also if you pool the Americium from 100 detectors together they become pretty dangerous.
Ahhhh gold old nuclear boyscout…
I forget the details, but each design has a use-case.
Though for most people, the newer design is likely the better choice.
If it had warnings about not opening it, or not containing user serviceable parts, don’t fuck with it.
Of course I understand caution with ⚡️, but just about everything has a ‘do not open’ label on it (in the litigous US anyway). Do we not care about right to repair?
I thought in the context of the question it was obvious what I’m referring to.
I had a problem with the control panel in my Panasonic microwave and was able to fix it pretty easily. Everything I needed to get to was inside the right front of the microwave; the control pad membrane and the sticker that goes on the front of it.
