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".

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.
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
CRT TVs.
Desktop computer power supplies. Don't open them.
How else am I supposed to put the magic smoke back in?
Air conditioner. I melted a screwdriver.
kids today don't know about the scary suction cup on crts
Pressure cooker
- 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.
I'm treating them like guns. Assume they're loaded until you prove otherwise.
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.

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).
Word for word my answer
This very much depends on your level of skill, experience and awareness of the dunning-kruger effect.
So basically, go for it?
This very much depends on your tolerance for ragrets.

Since dunning-kruger isn't valid, we're halfway there!
This whole thread is making me anxious
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.
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.
But the blue smoke kinda smells good
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.
Current smoke detectors still do, and usually have some warning on them stating such.
If it had warnings about not opening it, or not containing user serviceable parts, donβt fuck with it.

P.S. Fuck John Deere.
Eh, I'm not sure about that broad. Macbooks say not to open them because "reasons", but most items in there can be easily repaired
Of course I understand caution with β‘οΈ, 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?
