It’s probably a proprietary connector made specifically for Yamaha, or Yamaha made it themselves. It’s loosely based on car connectors from what I can see, but I don’t think you’re gonna find much info about it.

I’d just go in “guns blazing” with this thing. If there is a replacement for it and it’s fairly cheap I mean. If not, I’d try and pry the silicon off with some of my DIY tools for these sorts of situations.

I wish to know how to open this socket to access the rubber/silicone seal inside, and to know that first I need to identify the name of this connector

What exactly do you mean by this, is the connector sealed?

Oh, sorry, I completely misunderstood you, my bad 😔. With “hack it” I understood “hack the forum”, not the captcha.

Yeah, as I said, most factories closed by the end of the 70s, but some operated till the USSR dissolved.

The system wasn’t that bad to be honest… at least not in Yugoslavia. USSR was a different story. We had all the perks of the west with none of the obligations. Of course, you can’t compete with the western tech markets (yes, we did try that, look up Zastava, Yugo, Iskra, Gorenje) with a system like that, it’s just not designed to compete with capitalism, so it was doomed to fail when everyone around you is capitalist. Oh well, it was good while it lasted.

There are other open forums, free for registration. I could look up the URLs if you want, I have them in a plain text file on my PC (I’m on my phone right now), some are also good, like vinafix for example (not ex USSR, but still good, it’s Vietnamese). I haven’t visited them in years though, things might have changed. I started working in IT and just lost interest in that… no money, no point in doing it. Hardware is dirt cheap nowadays.

Oh, and the URL is remont-aud.net, not remont-aud.com, sorry my mistake 😁.

As I said, it’s not about learning Russian. There are tons of translation tools these days and time is of the essence (most of the time). No one has the time to learn how to hack these forums (unless you have an exploit tested and ready to go).

No, they were done with Nixie tubes by the end of the 70’s… well, most of them.

Jr. Highschool history teacher visited, said they employ old ladies in the Moscow subway to watch the escalators just because everyone needed a job.

That was one of the main problems with communism and socialism. Not enough incentive for education, so just make up jobs, no matter how stupid they are. We called those jobs “doorknob operators” in ex Yugoslavia. It was a shitty deal, but there was no incentive for a large portion of the population to actually learn something useful because even if you don’t have anything other than a 4th grade education, you still had to be part of the workforce, and instead of forcing people to actually get a degree (mind you the state was the only employer at that time, even though, at least in ex Yugoslavia, there was an option for venture capital and self-employment in the 80’s, but no one actually did it… or very few, and on a very small scale), they just went “the hell with it 🤦… just… do something”… which could have panned out in the long term, but no one could know.

So uh… what Soviet electronics forums should we be visiting OP?

remont-aud.com and electrotanya.com. The second one is free from registrations, but the first one, no… and they hold most of the goodies when it comes to device schematics.

There are others, some are hidden from search bots, some hidden completely… of course, invite only. It’s not always the schematics that are shared, but the knowledge and knowhow that is worth the effort. Most stuff does eventually get leaked though.

It’s not about learning Russian… it’s about getting info without having to bother hacking into the thing… which is gonna take a lot more than having to copy/paste snippets into Google Translate.

Yeah, I ran into those as well, but those are for fans with separate windings for different speeds, 1, 2, 3 or low, mid, high. You can’t use them for controlling a fan with one winding.

You can, I have, it works… good enough. It’s not supposed to work in that mode, with chopped up sine waves, but it’s not such a big deal if you keep the motor cool, and it will stay cool because it’s a fan, a table fan… just mounted on a wall… and the motor is practically exposed, so it will be directly cooled.

Could you share the links of those cheap ones? Are those IR/RF controlled? Cuz I know about these, but they don’t have remotes.

EDIT: This is what I had in mind, but this is for LED lighting…

I know what I’m doing and I know what I have to mod to make it work properly and within engineering limits (I am an engineer). I just don’t have the time to make one myself, I just don’t.

It’s a synchronous AC motor, about 100W (maybe less, haven’t measured it), single phase, 230V~, but what does this have to do with what I asked?

Might be cheap for western salaries, I make about 10K euros a year 🤷.

I can mod the controller to not catch fire… I just need a PCB anyway, I don’t need the case.

Yeah, saw these on AliExpress as well. They’re not cheap, they’re like $20. I was looking for something fairly simple, like $3 to $5, nothing fancy. I would even be OK with just 3 levels if it was fairly cheap.

Oh well, I guess I’m gonna have to make one myself… simple things are off the table on online shops from what I can see.

A lot of kids, a lit of screaming, yelling, cheering… no wonder 🤷.

evil laugh while resistor melts…

Apparently it wasn’t as hard as everyone thought it would be.

Maybe add a few hundred amps as well.

The sun: Damn it, I knew it 😠. I thought I was special 🥺.

Meeh, we all make mistakes buddy ☺️.

Even Keith Flint.

Yeah, IDK why, just feels kinda natural.
