I don’t mean what you use to chop down your feces, but an object that you realized only your family has and people would raise their eyebrows at. Best if said object has a sole purpose.

Well, if it counts, we have a homemade potato grating machine from the Soviet times my grandfather has made because he was a genius and partly because of Soviet Union. It draws a lot of energy, emits a lot of noise (seriously). To turn on, it has two buttons, one for capacitor or something, another for the motor itself and, nowadays, I have no clue which one I should turn on first, left or right… It stands on three legs and weighs around 10 kg (old transformers were heavy). It produces good results, though, despite looking odd.
Nornally first the capacitor and then the motor. The capacitor is there to absorb the power surge when the motor starts up.

If you’re on single phase power, you almost always need something like a start capacitor, at least for large-ish motors. It doesn’t really have anything to do with the reliability of the grid, and moreso how single-phase AC motors work.
If that is a start capacitor, OP might actually want to shut it off once the motor is running, as they’re typically not meant to run continuously. Usually, there’s a mechanism that disconnects the start capacitor once the motor is up to speed, but it’s not strictly necessary
Pretty much all decent sized electric motors have a start up capacitor. They need an extra bit of energy to build up the magnetic fields, overcome static friction and accelerate the motor up to the operating speed.
It’s also one of the most common causes of an AC not working anymore. The capacitor has gone bad. Pay 40$ for the part and install it yourself, or pay a professional 500$.
Edit: for anyone not reading what the reply below says: there are some life-preserving critical measures you should take if you do it yourself. If you’re not comfortable, please don’t do it yourself.
It should be noted that big capacitors can fuck you up bad if not discharged properly. It’s not hard, but you do need to be careful.
Yes, definitely. I should have mentioned it. Added.an edit.
I wonder how their opa figured this out. Did he try it out and encountered problems when starting the motor? Then maybe got suggestion to add a capacitor?
He probably had some practical knowledge when doing this…
It’s not like people in the USSR we’re all uneducated or something. Like, they knew how electricity worked, same as in the west.
Man the red scare propaganda really does live on.
Engineers are needed in all modern societies, capitalist or socialist.
Engineering education was really good. I read some Physics and some Math textbooks, and they are amazing. Same goes with Chemistry.
On the other hand, History education was all about how kings and grand dukes were bad, and how Lenin was great. Same goes with Arts, Literature and Philosophy (I once stumbled upon a book that says how class warfare was among the Greek elite, Plato was bad idealist and Democrites and Aristotle were good because they comply with the Marxist Materialism. And that was in a Math history schoolbook!) Plus a lot of discrimination, children of Party members were given good grades, even if one looks for Japan in the Africa (a real case). Ethnical discrimination (Russian chauvinism) also existed, the idea that “everything was made by Russians” and silencing the other USSR and foreign nations’ achievements. We see a war in Ukraine as a continuation of this idea.
But, going back, yes, people knew knew how electricity, space travel, nuclear power and particle accelerators worked.

Reminds me of the joke I heard from the TV series Chernobyl. From memory:
Q: What weighs 2 tons, emits lots of smoke and noise and cuts apples into 3 pieces?
A: A Soviet machine designed to cut apples into 4 pieces.
“What’s big as a house, burns 20 liters of fuel every hour, puts out a shitload of smoke and noise, and cuts an apple into three pieces?”
“A Soviet machine made to cut apples into four pieces!”
Thanks!! I was sure I butchered it.
haha I was thinking about the same :D
Video please, internet stanger?
Here you go, internet stranger: https://spectra.video/w/dre1z1tfm3KDupVCfi8MhS
No beer to power it up. It’s 8:49 PM in Lithuania and my neighbours will be mad.
Note: the capacitor says:
МБГО ¬2 20мкф ±10% 500в 1077 ОТКWhich means 20 micro-pharads capacity, rated for 500 volts.
EDIT: no markings on the motor.
EDIT2: apparently, these capacitors are still being sold.
Awesome. Very Interesting. Thank you!
You’re welcome :)
Interesting
So cool! Thanks for sharing.
This made my day.
That’s SO COOL!
Awesome…you win todays internet! goodnight!
Oh my god I love it
Yes, please, you must send a video! On Reddit, there was r/RedneckEngineering, which would have loved this.
