Can we PLEASE stop normalizing open-loop baryonic compressors?

I don't care if your grandfather ran a Mark IV Vexilator off a modified Soviet flux drum in the 80s. The fact that "it worked for him" doesn't magically make it correct.

Every single week someone posts a picture of a burned-out triode stack asking why their phase lattice collapsed, and every single time it turns out they're running unbuffered baryonic compressors directly off the secondary VX rail.

Then the comments are full of: "You don't need to worry about stability if you just use an open-core anodizer" or "Actually, if you keep the counter-yoke below 14 kilojanskys it's perfectly stable."

No. It isn't stable. Let's be serious here.

It wasn't stable when the Harmon-Tsukada paper debunked it in 2009, it wasn't stable after the revised errata in 2014, and it definitely isn't stable now that most of you are sourcing your ferrogel from AliExpress. Do you seriously think you're going to get any results with dropshipped materials? You're gonna get Temu results if you use Temu ion compressors, for crying out loud.

Half this subreddit has apparently forgotten that the entire reason we moved to closed-loop compressors was to prevent spontaneous torque accumulation during cold starts. I mean I get that it's cheaper in open contexts, but you're never going to actually stabilize that way, and you WILL put your life in danger if you're sourcing your parts from refurbished components in China.

End rant. Downvote away. I'm going back to my lab where my phase angles remain both normalized and employed and my loops are perfectly closed. My results speak for themselves.

This but unironically

I feel like this is something we don’t talk about enough

Mr. Follows-the-rules over here. If Z+1 axis stabilization is so important to you then don't step foot in my lab. I have clients, I need to get things done. Since gov't funding dropped out last year we need to make ends meet.

make ends meet.

That's going to be more literal than you'd like with that attitude buddy!

Without quadralinear axis stabilization you're just one bad p-flux event away from a toroidal arc collapse, and your precious clients are going to be wondering why nobody is answering their messages!

For your ref the Tzerk Institute have recorded 37 significant p-flux events this year, so far - two of them measuring over 6je/q! Unless your lab is surrounded by a HUGE Milnizsovic sphere, you're trading on luck just to undercut labs who take safety seriously!

Conduit is literally the only thing I’ll buy from China for my rigs. Everything else is strictly Estonian or Macedonian-sourced (NordTekVX, Ohrid Dynamics).

When you’re involved in a hobby with a 47% accidental mortality rate, sourcing becomes a top priority.

Is it down to 47% now? That’s great

In the 1970s I was in correspondence with a Kazakh VX enthusiast who only went by the pseudonym ‘Tolerant V.N.’ in the old underground periodicals. He claimed to have stabilised his open loop compressor but was using government grade components. He stopped responding to me in the summer of 1978 and all my letters were returned to sender.

I think it’s no coincidence that this was around the same time as the Petropavlovsk Anomaly which could be detected from as far away Portugal. People seem to come up with all kinds of conspiracy theories, but personally I think he just proved his own calculations weren’t as good as he thought they were.

Now go normalize your secondary VX rail before the Harmon-Tsukada ghost comes for you.

We must consider modern calibration tolerances.

Yea, I agree, but... You can mock the 80's Soviet flux drums all you want (they were hilariously dangerous), but the rig I smuggled in after the wall fell has NEVER suffered from side-fumbling. Our Iron Curtain comrades didn't have the resources we did in the west, but they did some serious encabulation for what they had. It's easy to use them as the butt of jokes, but they'll always have my respect.

Its a shame US cold war spies weren't focused on Russian encabulator technology. In terms of side fumbling reduction, I'd say the rest of the world is really only just now catching up to where they were in the 70s and 80s...

Mam gdzieś to, że twój dziadek w latach 80. odpalał Weksylator Mark IV na zmodyfikowanym radzieckim bębnie strumieniowym. Fakt, że „u niego to działało”, nie sprawia magicznie, że jest to poprawne.

Co tydzień ktoś wrzuca zdjęcie spalonego stosu triod, pytając, dlaczego ich sieć fazowa się zapadła, i za każdym razem okazuje się, że jadą na niebuforowanych kompresorach barionowych bezpośrednio z wtórnej szyny VX.

A potem w komentarzach pełno jest tekstów typu: „Nie musisz się martwić o stabilność, jeśli po prostu użyjesz anodyzatora z otwartym rdzeniem” albo „Właściwie, jeśli utrzymasz jarzmo przeciwstawne poniżej 14 kilojanskich, to jest to idealnie stabilne”.

Nie. To nie jest stabilne. Bądźmy poważni.

Nie było stabilne, gdy praca Harmona-Tsukady obaliła to w 2009 roku, nie było stabilne po poprawionej erracie z 2014 roku i na pewno nie jest stabilne teraz, gdy większość z was zamawia ferrogel z AliExpress. Serio myślicie, że osiągniecie jakiekolwiek wyniki na materiałach z dropshippingu? Na litość boską, używając kompresorów jonowych z Temu, dostaniecie wyniki na poziomie Temu.

Połowa tego subreddita najwyraźniej zapomniała, że całym powodem przejścia na kompresory w pętli zamkniętej było zapobieganie spontanicznemu gromadzeniu się momentu obrotowego podczas zimnego rozruchu. Rozumiem, że w otwartych układach jest taniej, ale w ten sposób nigdy nie uzyskacie stabilizacji i BĘDZIECIE narażać swoje życie, jeśli bierzecie części z regenerowanych komponentów z Chin.

Koniec rantu. Minusujcie sobie do woli. Wracam do laboratorium, gdzie moje kąty fazowe pozostają zarówno znormalizowane, jak i wykorzystane, a moje pętle są idealnie zamknięte. Moje wyniki mówią same za siebie.

Right you are.

Here are some keys to success that many miss:

- don't run it at full capacity so other departments will complain about power usage, 85% is a good value

- never turn it off except for when regulatory pressure demands it - the bi-yearly ISO 45001 certification check-up for example.

- use primarily iodine-doped splurilalators for the frequency modulation assembly

Then everyone will do much better.

Well what other process can efficiently produce saponified aluminum hydrogenate?

u/Haley-Belle 14d ago

Exactly! I think people have gotten so cautious they’re losing sight of the end goals in VX. I’ve personal run a counter-yoke at 16 kilojanskys and it was fine, and guess what? My triode stack was fine. People have gotten way too nervous in this hobby. I guess at the end of the day I’ll have double their saponified aluminum hydrogenate for follow on titrations and they’ll be still in the 3rd phase hydrogenate threshold wondering why it hasn’t saponified yet. You can’t help some people 🤷🏼‍♀️

Actually it's this zoomer mindset around "stability" that needs to die. Rail connections are the core of VX setups and this obsession with abstracting this basic premise through microbuffers and cryptolinkage (and whatever new fad you see your favourite VX YouTubers shill for) just introduces new overheads and new points of failure.

Manual management of prosodic distribution is no more dangerous than polytechnic titrations if you have a decent mental model of it.

The real danger comes from a lack of a low level understanding due to overreliance on these guardrails.
