Analysis of front mold thread core pulling mechanism

When we design molds, we occasionally encounter products with threads. External screw products can be half-exited by front and rear molds, or two sliders can be undercut. For products with high requirements for internal threads, only thread core pulling mechanism can be used. Here is a set of front mold thread core pulling mechanism molds for everyone. Through product analysis, it is found that…

The urge to create smth more elaborate/decorative from the original base design vs both the desire to keep it simple enough to draw repeatedly and the need to have it read clearly, all while keeping it distinct and recognizable 🙃

MIT libraries are thriving without Elsevier

I'm coming to BURNING MAN! On TUESDAY (Aug 27) at 1PM, I'm giving a talk called "DISENSHITTIFY OR DIE!" at PALENQUE NORTE (7&E). On WEDNESDAY (Aug 28) at NOON, I'm doing a "Talking Caterpillar" Q&A at LIMINAL LABS (830&C).

Once you learn about the "collective action problem," you start seeing it everywhere. Democrats – including elected officials – all wanted Biden to step down, but none of them wanted to be the first one to take a firm stand, so for months, his campaign limped on: a collective action problem.

Patent trolls use bullshit patents to shake down small businesses, demanding "license fees" that are high, but much lower than the cost of challenging the patent and getting it revoked. Collectively, it would be much cheaper for all the victims to band together and hire a fancy law firm to invalidate the patent, but individually, it makes sense for them all to pay. A collective action problem:

Musicians get royally screwed by Spotify. Collectively, it would make sense for all of them to boycott the platform, which would bring it to its knees and either make it pay more or put it out of business. Individually, any musician who pulls out of Spotify disappears from the horizon of most music fans, so they all hang in – a collective action problem:

https://pluralistic.net/2024/06/21/off-the-menu/#universally-loathed

Same goes for the businesses that get fucked out of 30% of their app revenues by Apple and Google's mobile business. Without all those apps, Apple and Google wouldn't have a business, but any single app that pulls out commits commercial suicide, so they all hang in there, paying a 30% vig:

https://pluralistic.net/2024/08/15/private-law/#thirty-percent-vig

That's also the case with Amazon sellers, who get rooked for 45-51 cents out of every dollar in platform junk fees, and whose prize for succeeding despite this is to have their product cloned by Amazon, which underprices them because it doesn't have to pay a 51% rake on every sale. Without third-party sellers there'd be no Amazon, but it's impossible to get millions of sellers to all pull out at once, so the Bezos crime family scoops up half of the ecommerce economy in bullshit fees:

This is why one definition of "corruption" is a system with "concentrated gains and diffuse losses." The company that dumps toxic waste in your water supply reaps all the profits of externalizing its waste disposal costs. The people it poisons each bear a fraction of the cost of being poisoned. The environmental criminal has a fat warchest of ill-gotten gains to use to bribe officials and pay fancy lawyers to defend it in court. Its victims are each struggling with the health effects of the crimes, and even without that, they can't possibly match the polluter's resources. Eventually, the polluter spends enough money to convince the Supreme Court to overturn "Chevron deference" and makes it effectively impossible to win the right to clean water and air (or a planet that's not on fire):

Any time you encounter a shitty, outrageous racket that's stable over long timescales, chances are you're looking at a collective action problem. Certainly, that's the underlying pathology that preserves the scholarly publishing scam, which is one of the most grotesque, wasteful, disgusting frauds in our modern world (and that's saying something, because the field is crowded with many contenders).

Here's how the scholarly publishing scam works: academics do original scholarly research, funded by a mix of private grants, public funding, funding from their universities and other institutions, and private funds. These academics write up their funding and send it to a scholarly journal, usually one that's owned by a small number of firms that formed a scholarly publishing cartel by buying all the smaller publishers in a string of anticompetitive acquisitions. Then, other scholars review the submission, for free. More unpaid scholars do the work of editing the paper. The paper's author is sent a non-negotiable contract that requires them to permanently assign their copyright to the journal, again, for free. Finally, the paper is published, and the institution that paid the researcher to do the original research has to pay again – sometimes tens of thousands of dollars per year! – for the journal in which it appears.

The academic publishing cartel insists that the millions it extracts from academic institutions and the billions it reaps in profit are all in service to serving as neutral, rigorous gatekeepers who ensure that only the best scholarship makes it into print. This is flatly untrue. The "editorial process" the academic publishers take credit for is virtually nonexistent: almost everything they publish is virtually unchanged from the final submission format. They're not even typesetting the paper:

https://link.springer.com/article/10.1007/s00799-018-0234-1

The vetting process for peer-review is a joke. Literally: an Australian academic managed to get his dog appointed to the editorial boards of seven journals:

https://www.atlasobscura.com/articles/olivia-doll-predatory-journals

Far from guarding scientific publishing from scams and nonsense, the major journal publishers have stood up entire divisions devoted to pay-to-publish junk science. Elsevier – the largest scholarly publisher – operated a business unit that offered to publish fake journals full of unreveiwed "advertorial" papers written by pharma companies, packaged to look like a real journal:

https://web.archive.org/web/20090504075453/http://blog.bioethics.net/2009/05/merck-makes-phony-peerreview-journal/

Naturally, academics and their institutions hate this system. Not only is it purely parasitic on their labor, it also serves as a massive brake on scholarly progress, by excluding independent researchers, academics at small institutions, and scholars living in the global south from accessing the work of their peers. The publishers enforce this exclusion without mercy or proportion. Take Diego Gomez, a Colombian Masters candidate who faced eight years in prison for accessing a single paywalled academic paper:

https://www.eff.org/deeplinks/2014/07/colombian-student-faces-prison-charges-sharing-academic-article-online

And of course, there's Aaron Swartz, the young activist and Harvard-affiliated computer scientist who was hounded to death after he accessed – but did not publish – papers from MIT's JSTOR library. Aaron had permission to access these papers, but JSTOR, MIT, and the prosecutors Stephen Heymann and Carmen Ortiz argued that because he used a small computer program to access the papers (rather than clicking on each link by hand) he had committed 13 felonies. They threatened him with more than 30 years in prison, and drew out the proceedings until Aaron was out of funds. Aaron hanged himself in 2013:

https://en.wikipedia.org/wiki/Aaron_Swartz

Academics know all this terrible stuff is going on, but they are trapped in a collective action problem. For an academic to advance in their field, they have to publish, and they have to get their work cited. Academics all try to publish in the big prestige journals – which also come with the highest price-tag for their institutions – because those are the journals other academics read, which means that getting published is top journal increases the likelihood that another academic will find and cite your work.

If academics could all agree to prioritize other journals for reading, then they could also prioritize other journals for submissions. If they could all prioritize other journals for submissions, they could all prioritize other journals for reading. Instead, they all hold one another hostage, through a wicked collective action problem that holds back science, starves their institutions of funding, and puts their colleagues at risk of imprisonment.

Despite this structural barrier, academics have fought tirelessly to escape the event horizon of scholarly publishing's monopoly black hole. They avidly supported "open access" publishers (most notably PLoS), and while these publishers carved out pockets for free-to-access, high quality work, the scholarly publishing cartel struck back with package deals that bundled their predatory "open access" journals in with their traditional journals. Academics had to pay twice for these journals: first, their institutions paid for the package that included them, then the scholars had to pay open access submission fees meant to cover the costs of editing, formatting, etc – all that stuff that basically doesn't exist.

Academics started putting "preprints" of their work on the web, and for a while, it looked like the big preprint archive sites could mount a credible challenge to the scholarly publishing cartel. So the cartel members bought the preprint sites, as when Elsevier bought out SSRN:

https://www.techdirt.com/2016/05/17/disappointing-elsevier-buys-open-access-academic-pre-publisher-ssrn/

Academics were elated in 2011, when Alexandra Elbakyan founded Sci-Hub, a shadow library that aims to make the entire corpus of scholarly work available without barrier, fear or favor:

https://sci-hub.ru/alexandra

Sci-Hub neutralized much of the collective action trap: once an article was available on Sci-Hub, it became much easier for other scholars to locate and cite, which reduced the case for paying for, or publishing in, the cartel's journals:

https://arxiv.org/pdf/2006.14979

The scholarly publishing cartel fought back viciously, suing Elbakyan and Sci-Hub for tens of millions of dollars. Elsevier targeted prepress sites like academia.edu with copyright threats, ordering them to remove scholarly papers that linked to Sci-Hub:

https://svpow.com/2013/12/06/elsevier-is-taking-down-papers-from-academia-edu/

This was extremely (if darkly) funny, because Elsevier's own publications are full of citations to Sci-Hub:

https://eve.gd/2019/08/03/elsevier-threatens-others-for-linking-to-sci-hub-but-does-it-itself/

Meanwhile, scholars kept the pressure up. Tens of thousands of scholars pledged to stop submitting their work to Elsevier:

http://thecostofknowledge.com/

Academics at the very tops of their fields publicly resigned from the editorial board of leading Elsevier journals, and published editorials calling the Elsevier model unethical:

https://www.theguardian.com/science/blog/2012/may/16/system-profit-access-research

And the New Scientist called the racket "indefensible," decrying the it as an industry that made restricting access to knowledge "more profitable than oil":

https://www.newscientist.com/article/mg24032052-900-time-to-break-academic-publishings-stranglehold-on-research/

But the real progress came when academics convinced their institutions, rather than one another, to do something about these predator publishers. First came funders, private and public, who announced that they would only fund open access work:

https://www.nature.com/articles/d41586-018-06178-7

Winning over major funders cleared the way for open access advocates worked both the supply-side and the buy-side. In 2019, the entire University of California system announced it would be cutting all of its Elsevier subscriptions:

https://www.science.org/content/article/university-california-boycotts-publishing-giant-elsevier-over-journal-costs-and-open

Emboldened by the UC system's principled action, MIT followed suit in 2020, announcing that it would no longer send $2m every year to Elsevier:

https://pluralistic.net/2020/06/12/digital-feudalism/#nerdfight

It's been four years since MIT's decision to boycott Elsevier, and things are going great. The open access consortium SPARC just published a stocktaking of MIT libraries without Elsevier:

https://sparcopen.org/our-work/big-deal-knowledge-base/unbundling-profiles/mit-libraries/

How are MIT's academics getting by without Elsevier in the stacks? Just fine. If someone at MIT needs access to an Elsevier paper, they can usually access it by asking the researchers to email it to them, or by downloading it from the researcher's site or a prepress archive. When that fails, there's interlibrary loan, whereby other libraries will send articles to MIT's libraries within a day or two. For more pressing needs, the library buys access to individual papers through an on-demand service.

This is how things were predicted to go. The libraries used their own circulation data and the webservice Unsub to figure out what they were likely to lose by dropping Elsevier – it wasn't much!

https://unsub.org/

The MIT story shows how to break a collective action problem – through collective action! Individual scholarly boycotts did little to hurt Elsevier. Large-scale organized boycotts raised awareness, but Elsevier trundled on. Sci-Hub scared the shit out of Elsevier and raised awareness even further, but Elsevier had untold millions to spend on a campaign of legal terror against Sci-Hub and Elbakyan. But all of that, combined with high-profile defections, made it impossible for the big institutions to ignore the issue, and the funders joined the fight. Once the funders were on-side, the academic institutions could be dragged into the fight, too.

Now, Elsevier – and the cartel – is in serious danger. Automated tools – like the Authors Alliance termination of transfer tool – lets academics get the copyright to their papers back from the big journals so they can make them open access:

https://pluralistic.net/2021/09/26/take-it-back/

Unimaginably vast indices of all scholarly publishing serve as important adjuncts to direct access shadow libraries like Sci-Hub:

https://pluralistic.net/2021/10/28/clintons-ghost/#cornucopia-concordance

Collective action problems are never easy to solve, but they're impossible to address through atomized, individual action. It's only when we act as a collective that we can defeat the corruption – the concentrated gains and diffuse losses – that allow greedy, unscrupulous corporations to steal from us, wreck our lives and even imprison us.

Unknown Pleasures.

I've been thinking about the possible, well, mechanics of Elster and Ariane's physical intimacy.

Specifically, whether it would be possible for Ariane to reciprocate, sexually, to Elster in some way - I have to think she'd want to, and it's hard not to imagine Elster wouldn't want to indulge her.

Some spicy musings on the possibilities to follow.

Obviously Elster isn't intended or built for sexual pleasure; we can actually probably assume that she doesn't even have genitals, if the black surface "shell" is indeed the exoskeleton Replikas are said to have. What we see when she salvages the arm and chestplate seems to suggest the same thing too, that her exterior as we see it is simply part of her body as a whole.

(I'm also inclined to interpret her "pod" as something closer to a dialysis machine than a bed or cot simply for sleeping - something that manages the waste products her external anatomy seems to make no allowances for, as far as we can tell.)

But we know from her behaviors that she definitely does have some kinds of sensation through this exterior - in particular, we know she has the approximate touch-feedback of a human, required to operate lots of the human-suitable mechanisms she comes across, and she does seem to feel some kind of pain when she's injured.

This makes sense - both these things serve obvious practical functions. Elster, as a combat engineering unit, needs to know how tightly a bolt is fitted every bit as accurately as she might have to know how hard she's squeezing a trigger; and pain is a useful thing for any organism as a self-preservation measure, especially prudent for a comparatively valuable unit type.

You can of course calibrate the roughly appropriate trigger pull standards for any number of weapons into your LSTRs as they're rolling off the production line - but the bolts, nuts, screws, panels and fittings she's going to work with in the field will all behave differently due to their unique conditions and environments. So she does definitely need to have a kind of sensation coming back, even if only to know how far to crank a wrench before it breaks something.

Following this logic, and maybe even the Nation's preference for efficiency and physical specialization in the Replikas, it would seem to me that the most sensitive interface points of her body are probably her hands, since those are the tools of her function.

As for pain - well, we know pain and pleasure in human bodies both occur via the same pathways, and given how closely Replika biology mimics that of a Gestalt, we have to assume that's just as true. Which is to say, if she can feel physical pain, she can potentially feel physical pleasure too - even if she isn't constructed with that in mind. It might just take some creativity, and some engineering knowhow to "hack" her body to use it this way, which I'm sure the two could muster between them.

Imagine then, if you will, Ariane and Elster experimenting with a jury-rigged contraption of multimeter and radio parts, wired in through the finer structures of her hands, to see if they can figure out how to induce the equivalent of organic pleasure through her existing sensory mechanisms.

Not just for a fun little experiment or to pass some time, you understand - but to find another way they can share and love each other in the freedom and isolation of their exile, even if it has to be invented. Another way for Ariane to reach for Elster despite the limits and restrictions the Nation has defined for them; another way for Elster to let her in.

Imagine Elster kneeling, so she won't fall if she is to be suddenly overwhelmed, hands outstretched like a religious devotee, while above her Ariane begins to tune into the responses she wants, chasing her ecstatic threshold like a radio operator might chase a precious, narrow, signal on the dial.

Imagine, once they'd started making a real science of it, that they'd want to bring more intimacy, more closeness into the process. Imagine Ariane sitting on Elster's torso in their cosy little bed cubby, studying her reactions as she makes herself an expert in them, taking her own pleasure in providing Elster's this time. Imagine her sitting on Elster's face while Elster faithfully offers their invention up to her, so that she can ensure as artfully as possible that they both come in time.

You might even imagine them getting real weird with it, refining and minimizing their devices, and installing parts into some of the cavity gap somewhere, like the space we've seen inside her torso, so Ariane can pop open a panel and reach inside to invent a new kind of powerful, visceral intimacy, one that's entirely unique to them.

Imagine the exchange of trust involved. Not just from Elster to Ariane either, but from Ariane to Elster; both in sending her fragile human hands into the unyielding structures of her lover's armored and artificial body, and in having to rely on Elster not to let her do any harm, even from well intended ignorance.

Just some thoughts. Got thinking about the possibility Ariane might be curious to experiment with Elster's physiology, beyond basic maintenance, after seeing @arainydancer's great latest animation "Fixer", through no fault of hers.

IWTV Ep4 - Rewind the Tape

"How does Claudia joining Lestat and Louis’ family affect or change them, separately and also as a couple?"

@iwtvfanevents

IMO, Lestat saved Louis' life, but Claudia gave Louis a reason to go on living. Cuz unfortunately for Lou, he thinks his value came strictly from external sources; the value other people put on him & judged him by--his career & socio-economic status; his worth as a Black man (a product of slavery and the literal value/prices put on Black bodies; how his role/actions affected "my people"); his orientation ("identifying as a homosexual," "embracing my sexuality"); and his place/dynamic within the nuclear family unit (at the DPDL estate, and at 1132 Rue Royale).

By Ep3, Louis had lost everything--out of business when Storyville was shut down; thoroughly disrespected by white racists at every turn, from Ordinance 4118's segregation bill & Finn O'Shea "a white man who used to work for me" burning down the Azalea after stealing his money to open his own "No Coloreds Allowed" competitor, to Tom & the Alderman screwing him over ("a dumb pimp who got robbed blind years ago"); his white husband cheating on him with a white woman that used to work for him & laughing in his face about it; and Lou dumping Les during the race riots on the night Lestat wanted to make "our anniversary."

But ironically, Les had a point about making that night their "anniversary:" a night of change, evolution, transformation & rebirth for ALL of them--most obviously for Claudia, the baby phoenix vampire rising from Storyville's ashes, but for Loustat too.

IWTV focuses on how Louis was affected & changed by gaining Claudia, first as a daughter & then as a "sister." She became his central axis--everything revolved around her. Louis had discovered what unconditional love truly meant.

That was something Lou'd NEVER experienced before. Everyone's love for him came with conditions, clauses, terms of service--from Grace's conservative judgementalism, to Paul's dogmatic religiosity, to his p.o.s. mother's resentment, hate & homophobia. The affection b/t Lou & Lily was a transaction bought & paid for. And where to even start with Monsieur "Without Apology" de Lioncourt. 😒 And in turn, Louis' love was tainted--he lost touch with Grace, he was blamed for Paul's suicide (and likely blamed himself sometimes), his relationship with his mother had been ruined LONG before he became a vampire, and Lestat...jfc.

But in Claudia, Louis could finally pour all of his love & attention & affection on someone who could love him back, tabula rasa, a newborn vamp who just wanted food, home, comfort, safety & love from him, with all a child's demanding.

Sadly, Claudia did NOT love Louis unconditionally. By the end, she genuinely hated him (and ofc Lestat), for all the ways he'd "dragged his family into this mess" (especially in Paris), and hopelessly "failed" her, and chose other men over her (regardless of whether or not he really DID, that was how SHE FELT). Lou'd learn the hard way in Merrick that NOTHING he'd given her had been enough.

As horrific as it was, Merrick was the best thing for Lou; forcing himself to face Claudia's ghost, her diaries, and her true feelings about him. In the end, he had to learn that loving people (and being loved) couldn't be a crutch, or his reason to keep living or not.

Lou'd HATED himself his entire life, deeply depressed & full of "self-loathing;" and after losing Claudia he couldn't pretend to be happy anymore (even w/ Armand, despite how long they stayed together).

Same goes for Lestat. For all his vain cocksure braggadocio, Lestat hated himself too. (Despite claiming he didn't in ToTBT.)

Lestat thought his value came from what he could provide/give/do for others--the gentle son who stayed by his mother Gabrielle when the Marquis & his horrid brothers abused them; the Wolfkiller who saved the town & hunted food for his family; the gallant hero/lover who rescued the damsel in distress & whisked them away on a whirlwind adventure/romance (Gabrielle, Nicki, Louis, etc). Whatever people wanted, he'd give them, lovebomber supreme.

This ultimately culminated in his role as the vampire Maker, the god of his own Savage Garden, creating the world through his image of what he felt the world was/should be like (a la the Chateau Era).

Cuz he suffered from chronic abandonment issues--everyone he'd loved most had betrayed him & left him--first & foremost God.

So it all snowballed from Lestat's own traumatic childhood, trying to find God (freedom, food, home, comfort, safety & love) but being dragged back into Hell over & over (LITERALLY in Memnoch).

And trying to connect with his fledglings & being abandoned over & over, as vampirism had turned Lestat into a monster/the Devil.

Claudia effed up Les' God Complex, but he needed that humbling. He needed to take accountability for all the things he'd done wrong, and the ways he'd failed as her Maker/Creator/Father. Cuz we know Les loved her deeply in the books--he just didn't know HOW to love.

Together, I think Loustat was most affected/changed by having Claudia in the way they were able to come back together and rekindle their love for e/o through loving Claudia--she really was an effective bandaid gluing them together, when Lou would've left Les in Ep3.

Claudia was an outlet for Loustat: she gave Louis someone he felt he could "do right" by (after he'd failed Grace & the kids), and she gave Lestat someone he could bond with as a sadistic vampire killer.

So yeah, Loustat (mostly Louis) did the best he could by Claudia, but we see where the road to Hell is paved with good intentions.

Ultimately, in the books, Loustat is only able to come together to "do right" by another daughter when they take in Rose; making up for the mistakes they made with Claudia. (But even there, we see the ways Rose still suffered from loneliness/abandonment, especially when Lestat over-corrected by giving her more freedom & autonomy by being more hands-off & distant, instead of overbearing & controlling.)

Super Duplex S32760 Flanges Manufacturers in India

The manufacturer and supplier of Very Duplex Steel Flanges made their products in a variety of sizes and forms for the customer in response to interest. The manufacturer, stockist, and supplier of the entire stainless steel item, including this, is Sankalp Alloys Overseas. They provide everything and deliver the product while maintaining excellent quality and price as well.

Super Duplex Steel Flanges are regarded as the best in the series of steel Flanges based on their characteristics and strong points. The austenitic toughened steel is offered in Very Choice with a few components like copper, zinc, and chromium. The majority of businesses use a lot of Duplex steel products since they provide high strength when they come into touch.

There are many kinds of Flanges accessible, for example, Welding Neck Wall It is by and large utilized in low-temperature and high-pressure applications since they required the unhindered liquid stream conveyed by the line framework. Long welding Neck-They is equivalent to a weld neck just contrast in a lengthy welding neck the tightened center point (neck) is expanded and performs like an exhausting expansion. Slip-on Spine It is appended to the fittings or the line by two filet welds, one external the hole and the other one executed inside the rib. They are handily perceived by their minimal and thin shape.

Strung Rib This is attached by screwing the line into the spine rather than using a crease weld. They are typically used in small, low-temperature, low-stress applications like utility and water management. They are legally required in dangerous areas like petrol stations and industries. Since welding associations could be dangerous in this type of environment. Spine Attachment Weld To connect this type of rib to the lines, a single fillet weld is performed on the exterior of the rib. Joint-joint ribs This spine frequently uses an alloy with a stub end and a component with a level spacing. Dark Spine Due to the necessary catapulting forces and the structure pressure, these Flanges reduce outstanding mechanical forces.

A few other exceptional sorts of rib are Nipo rib, Weldo rib, Turn Rib, Elbo Rib, Lactro Rib, Growing spine, and Lessening Rib.

[foggyparadisecandy]

On Guilt vs Shame

People get this wrong all the time so here's a way to frame it up:

Guilt is a sense that "I did something wrong."

Shame is "I am fundamentally flawed as a human being."

Guilt can be productive because it requires you to understand who you want to be and how you want to be perceived. And if you do something that isn't in alignment with that, guilt is a complex mechanism that tells you "I might need to look into this and adjust either how I'm acting or how I want to be perceived."

Guilt can also be triggered if you acted perfectly in alignment with your beliefs but you come to find that you have hurt someone else or done something that is harmful to someone else. A well-meaning effort, as you intended, might have landed wrong because of something you weren't aware of. When you become aware of the new information, then you can adjust (if you choose to) in the future.

Guilt is based on the external world for the most part - how were you or your actions pereceived by others.

Shame can be overwhelming and debilitating. Usually shame is internal focused and based on assumptions that you are being judged harshly by others. Although in reality, you are usually putting it on yourself.

In this internal preoccupation, you might end up berating and beating yourself up with shame. Some people will do this as a path to forgiveness but it can be extremely destructive to your ego and self-esteem, and does NOTHING to help fix whatever triggered your shame.

Let's say you do something awful and hurt a friend horribly, and you feel ashamed and start beating yourself up. That self-hate and being angry with yourself will consume your mind and time. What might be a better course of action is to make amends. Reach out and apologize and attempt to fix the situation, if possible, or explain how you will make sure it doesn't happen again.

Guilt can lead to shame so you need to watch out for the non-productive mechanics around shame.

Bottom line: if you are feeling shame, take a breather, and figure out what triggered the shame, get out of your head, and take positive steps to resolve the core issue with the external parties so you can repair relationships if you feel it's warranted.

Not all guilty feelings need action. If you screwed up, and it's irreparable, well then, just learn what to do next time to keep your behavior and your self view in alignment.

I'm still figuring all this out so if you disagree or want to add something, I would love to hear it.

I hope this helps you keep track of guilt and shame in your life and focus on positive outcomes.

So here's the new toy that's been distracting me the last couple days. My decade+ old oversized ASUS gaming laptop finally pooped out several months ago, leaving me daily driving my Steam Deck of all things as my main home computer. And don't get me wrong, the Deck has performed remarkably well in that regard, but I've been meaning to get something a bit fancier for a while. Something that could handle 1440p gameplay at a decent framerate while streaming or recording, can manage image and video editing well, and in particular can run some VR games. I've been interested in VR gaming ever since Lobac posted about some of that a while back, especially with the Meta Quest 2 being a solid headset at a really aggressive cost. With the Zuck giving up on the metaverse, the Quest is likely never going to be cheaper than it is now.

I'd waffled for a while about building a PC, but in the end I psyched myself out and decided to go with a pre-built instead. Yes, that means willfully overpaying for the end product by a few hundred bucks to pay someone else to do the assembly and initial set up for me, but in exchange I only had to research one product instead of half a dozen separate components, plus there's a single warranty where if anything doesn't work it's somebody else's problem to fix it, and I'd only have to deal with a delay.

After watching and reading a bunch of reviews, Skytech seemed to be a decent choice for system integrator, with solid to positive reviews for various prebuilt models they offer, including Gamer's Nexus who tend to be pretty harsh on pre-builts. But it was this review from JustIN Tech that sold me on this Azure 2 model. "Performance equivalent to last gens best, but at half the price" is the exact tag line I was looking for, and after a recent price discount it was just within my $2k range.

In retrospect though, I should have done some more research on the specific components. I'm quite happy with the intel 13600 cpu, and while the included cooling setup is overkill for that chip, that just means I've got some free thermal space to overclock or upgrade in the future. Plus, it's pretty, and I'm shallow. On the other hand it turns out the nvidia 4070ti is not well thought of - generally considered badly overpriced, plus has the extra negetive association of being just a rebranding of the failed '4080 12gb' that was so roundly panned that its release had to be canned altogether. And the PNY model that came bundled in my unit isn't even as nice as the Gigabyte one in the JustIN Tech review. One of the reasons why Gamer's Nexus is the better channel for these sorts of reviews is that they do secret shopper and get the same stuff regular folks get, where as brands know what they're sending to channels like JustIN Tech and can take pains to make the best possible impression by including better components and taking extra care in assembly and packaging.

So what should I have purchased instead? I don't know. Maybe the 'blue' model of the same Azure 2 line, which is three hundred dollars cheaper to swap out the 4070ti for an intel Arc a770, which would probably have been more than enough for my intended use cases. Heck, with 4 extra gb of vram it might have even been better than the 4070ti for me in the long term, and if not then I could use the money saved towards swapping out to a better AMD card next gen. But the blue model comes in a blue version of the case, which wouldn't have made the swirly rainbow rbgs pop as much.

Anyway, while I might have made a different choice if I had done more research, that doesn't mean I'm at all unhappy with what I got! The Azure 2 arrived promptly. The build quality of the system is very nice. No damage, no loose or cross-threaded screws. Everything worked right out of the box when plugged in - including all the various external ports. Skytech certainly did a good job putting it all together. While the 4070ti might not be the most reasonably priced card for its performance level, now that it's here and paid for regardless, it seems like it should be able to do everything I want it to, at least for now. And if I end up replacing the gpu sooner then I would have liked, eh, we live and learn.

And while it doesn't matter at all compared to cost and performance, the swirly rainbow rgb lighting makes me feel like a Real Gamer (tm).

Desk is getting a bit cluttered tho.

As for performance, It's quiet and runs cool while playing my current games at top settings - though my particular game selection (mostly just Elden Ring on max settings with Ray Tracing), and my 1080p, 75hz monitor aren't exactly putting it through its paces yet. A new monitor is one of several upgrades & accessories I plan to get to go with this thing in coming months. New monitor, VR headset, an extra ssd on which to install linux - I figure I'll keep the windows install on the side, on the off chance there are games or utilities I can't get running in Linux down the line.

But anyway yeah, that's what I've been so busy with lately, delaying liveblog posts.

[whentherewerebicycles]

it is a rainy gloomy day. i got up early and had a good productive morning working on job materials until i was looking up something for my CV and discovered that my university... apparently gave the faculty/staff award i won this fall to someone else. i’m kind of baffled but mostly i feel pretty shitty about it, because... what? i just emailed the woman who notified me i’d won it to be like sorry can you... clarify what happened here... but i feel like regardless of her response i can’t list it on my CV because if you google it the first thing that comes up is the name and bio of someone who is not me. so i guess just... okay. trying to reserve uhh full bad feelings until after she responds... but what a fun way to get lightly screwed over on the way out. it mostly feels bad because there were so few external mechanisms in that job for recognizing quality work, and it was nice to have that tangible “you are doing good stuff here” recognition from the institution. so... okay. i might cry about it a little to vent the bad feelings and then try to uhh move on. sure wish i could go for a long walk!! i think i will set job stuff aside because i’m kind of in a funk bleh. i guess i will work on cleaning the house instead.

Main technical specification Model Products width(mm) Products thickness(mm) Capacity(kg/h) JW130+JW70 2200 1.5-12 600-700 JW150+JW90 2600 1.5-12 800-900 Note: The specifications are subject to change without prior notice. Product image display Transmission system The function of the drive system is to drive the screw and supply the torque and speed required by the screw in the extrusion process. It usually consists of a motor, a reducer and a bearing. Heating and cooling device Heating and cooling are necessary conditions for the plastic extrusion process to take place. 1. The extruder usually uses electric heating, which is divided into resistance heating and induction heating. The heating sheet is installed in the body, neck and head. The heating device heats the plastic in the cylinder externally to increase the temperature to reach the temperature required for the process operation. 2. The extruder cooling device is set to ensure that the plastic is in the temperature range required by the process. Specifically, it is to exclude the excess heat generated by the shear friction caused by screw rotation, so as to avoid the temperature being too high to make the plastic decompose, scorch, or shape difficult. The barrel cooling is divided into two types: water cooling and air cooling. Generally, small and medium-sized extruders are more suitable for air cooling, and large-sized ones are mostly water-cooled or combined with two forms of cooling. Read the full article

Mould Design in Plastic Injection Moulding 

Injection Moulding is an extremely versatile procedure.  It can be utilised for virtually any product. Injection moulding is the industry standard for manufacturing components for products.

There are some limitation needs to consider. Here are the rules to follow when designing your product to make sure quality and durability:

Wall Thickness

Keeping your walls thin will ensure a faster cooling rate and less materials used. Lower cooling rate and less material used will result in a shorter cycle time. This allows you more parts in a shorter amount of time, for less production cost

To strengthen parts, ribs are more effective than thicker walls. Adding ribs at right angles to a wall will add considerably to its overall strength. It is a common mistake to thicken the walls of a design to achieve this effect when ribs are a cheaper and more effective option.

Ribs should be about half the main wall thickness. There can be some leniency here, but not too much or the ribs will be completely ineffective. Half is the generally accepted standard and is more than enough to increase a wall’s strength.

Coherence

Try to make your design uniform throughout. That is, wall thickness, rib thickness and corner radii, for instance, should all be the same values. This will help the part to cool uniformly.

Corners & Edges

Corners could be an issue in a mould and will not come out flush. It is difficult to form plastic into a flawless corner. The outcome will look amateurish and messy, not to mention the power of the components can be compromised.

Corners and edges should be rounded wherever possible. Sharp edges do not always come out perfectly when the part is ejected from the mould.

Add a slight angle to the sides of your mould to allow easy release. A one- or two-degree angle should be applied to the mould on the face perpendicular to the parting line. This will allow for easy removal of the part from the mould.

Ribs

These are structural factors for your component, utilised for general stability control. Ribs are thin wall protrusions which extend vertically from a plane or wall. Adding ribs instead of thicker walls will provide greater structural support.

Bosses

These are empty, cylindrical protrusions. These are normally integrated in a style for accepting screws or other mating parts of your style. Making sure these are secured by attaching them a wall. Putting in ribs will means the bosses will stay straight as well as accommodate the part it was made for without an issue.

External Undercuts

A depression or protrusion in the exterior of the mould – the cavity half – could create issues if trying to divide parts from the mould. Adjust the parting line to lodge this.

Internal Undercuts and Overcuts

Related to external undercuts, these depressions or protrusions are within the mould – on the centre half. Adjust the parting line to lodge this.

Protrusions on the part that will snag on the mould core or cavity when it is opened can make it impossible to remove from the mould.

Threads

When your mould has a thread, always position it vertical to the parting column. This will make sure that the delicate thread isn’t damaged. It’s better, preferably, to not comprise a thread at all in the design. Making your design simple will lower the odd of something going wrong.

Injection mouldingdesign makes a superior product. The myriad possibilities far outdo the limitations. Designing for an excellent injection moulded part is the core of the design process.  These restrictions are the guidelines for making a flexible end product.

Colour use

Where possible, use lighter colours for your moulds. The mould is already cool when the molten material is being injected. As such it begins the setting process immediately and will sometime leave setting patterns. Using lighter colours will help y.to hide these patterns.

Injection mouldingis the industry standard for creating lasting, quality parts. To be able to take advantage of this technology your design must meet its minimum requirements. Small considerations are all it takes and the result is a successful product that will meet all of your quality needs.

Mounting methods for HDMI extenders

Although plenty of people buy a twisted pair network cable HDMI extender kit, few think about how to mount it properly.

In one of our articles (link to compact extenders) we talked about the hidden pitfalls of compact HDMI extenders. Now we would like to talk in detail about the "regular" kits. For the most part, they have a standard form: a metal case with a minimum set of inputs and outputs (HDMI, RJ45, power).

Of the new users of such kits, few understand the importance of its external appearance and configuration in terms of how it will be further installed in the room. When choosing a kit, it is important to consider the following question. How are you planning to position this device? Are you planning to hide this device on a table behind an NVR, TV, monitor, etc.? Or will the transmitter and receiver be placed in plain sight, e.g. on a wall, under a tabletop, or on a surface in some other way? That is why it is important to pay attention to its form factor and the kit itself.

Most extenders look like a regular box:

There are extenders that have special mounting brackets built into the case itself:

Lenkeng LKV372AE

You can also buy extenders with a set of removable brackets that can be attached to the surface of your choice with screws. Perhaps this is a successful combination of the first two options.

Lenkeng LKV676E

Some manufacturers offer additional rack mounting brackets for transmitters and receivers. But this is often offered with expensive professional equipment.

Courtesy of Kramer

Instead of conclusion

Professional installers have found their own ways of mounting the kits. They use double-sided tape, ties, or other methods. We agree that some sort of life hack can always be found. But at the same time, we want to draw your attention to the variety of devices that are meant for specific applications. We also want to point out that sometimes manufacturers try to facilitate the subsequent installation of their products and that is why they really deserve a special thanks.

Precision Thread Milling on Swiss Lathes

In the realm of high-precision manufacturing, the demand for small, complex components is steadily rising, leading to a focus on both the accuracy and efficiency of threading operations. The Swiss lathe, known for its outstanding stability and precision, has become an ideal platform for performing thread milling. Thread milling is widely used in industries such as medical devices, aerospace, and electronics, especially in high-volume production. This article delves into the essentials, advantages, and applications of thread milling on Swiss lathes.

1. Introduction to Thread Milling

Thread milling is a process where a rotating tool cuts a thread by following a helical path on the workpiece surface. Unlike traditional tapping or single-point threading, thread milling requires precise CNC control of multiple axes, typically X, Y, and Z, to follow an accurate threading path. This process allows for the cutting of both internal and external threads and is particularly effective on Swiss lathes due to their sliding headstock and guide bushing system, which ensures stability and precision during threading.

Thread milling also offers flexibility and adaptability, enabling the machining of threads with varying specifications—a crucial feature for producing complex, high-precision parts.

2. Choosing the Right Thread Milling Tools

The selection of thread milling tools is crucial for achieving high precision and efficiency. Carbide thread mills are commonly used, as they handle high speeds and feeds well and provide durability in tougher materials like titanium and stainless steel.

Thread mills can be categorized as either single-point or multi-point tools. Single-point thread mills are versatile, suitable for multiple thread sizes and pitches by altering the toolpath in the CNC program. Multi-point thread mills, though faster, are usually designed for specific thread specifications. The choice of tool should be based on the specific requirements of the part being manufactured to achieve the best results.

3. Programming and Toolpath Strategies

Thread milling on a Swiss lathe requires precise programming to coordinate multiple axes and ensure the accuracy of thread geometry. CNC programs for thread milling typically employ helical interpolation, which simultaneously moves the tool along the X, Y, and Z axes, creating the helical path necessary to produce a thread.

To avoid tool breakage and maintain accuracy, thread milling generally requires multiple passes to reach the desired depth. Each pass progressively cuts deeper, ensuring the threads are formed with consistent depth and pitch accuracy. Proper programming is essential to control feed rates and pitch, ensuring the finished threads meet specification.

4. Advantages of Thread Milling on Swiss Lathes

Compared to traditional threading methods, thread milling on Swiss lathes provides several significant advantages:

High Flexibility: By adjusting parameters in the CNC program, a single thread mill can produce threads of various sizes and pitches, enhancing flexibility and reducing tooling changes.

Improved Chip Control: Unlike tapping, thread milling generates smaller, more manageable chips, which are less likely to cause blockages or damage the guide bushing.

Lower Cutting Forces: Thread milling generally requires lower cutting forces, making it ideal for thin-walled or small-diameter parts, where excessive force could lead to deformation.

Reduced Risk of Tool Breakage: Thread milling produces fine chips that are easier to clear, significantly reducing the risk of tool breakage—especially important in hard materials like stainless steel and titanium.

5. Applications of Thread Milling

Thread milling has found widespread use in several key industries:

Medical Devices: In producing bone screws and implants, thread milling ensures precise, high-quality threads while minimizing stress on delicate components.

Aerospace: The high precision of Swiss lathes makes them ideal for small-diameter, high-strength fasteners used in aerospace applications.

Electronics: Thread milling is particularly suited for creating small-threaded components, such as connectors in electronic devices, where high precision is required.

6. Tips for Effective Thread Milling on Swiss Lathes

Successful thread milling on Swiss lathes requires careful attention to operational details:

Optimize Feed Rates and Speeds: Use recommended cutting parameters from the tool manufacturer to prevent premature tool wear or breakage.

Optimize Toolpath: Whenever possible, use climb milling, which reduces tool deflection and can enhance surface finish.

Ensure Proper Coolant and Lubrication: Adequate coolant flow controls cutting temperature, prolongs tool life, and helps prevent material deformation from overheating.

Conclusion

In the field of high-precision manufacturing, thread milling on Swiss lathes stands out as a flexible, accurate, and efficient technique, ideal for producing small, complex parts. By selecting the right tools, programming accurately, and carefully managing cutting parameters, thread milling can significantly enhance both the quality and efficiency of threading operations. As technology advances, thread milling on Swiss lathes is expected to see expanded applications across industries, driving innovation in precision machining.
