There's an Aztec city building game called Tlatoani. It's in early access, but has enough meat on the bone that it's one of my goto games.

Out of curiosity I checked Steam DB for active player numbers. I have discovered at any given point I am 10% to 25% of the given player base BY MYSELF. I am 1 of 4 people playing this game right now in the world. With the prevalence of the internet I always assume whatever weird bullshit you're into there's at least a thousand people talking about it; making memes outsiders could never comprehend. It's actually novel to fly under the radar for once.

What do you do that doesn't have a community associated with it?

    Earlier this year I tried out a Steam demo of a game called "That Time I Found a Box" and got hooked on it. It's a very unique card game where you create and enhance the cards as you play. I played it for days and eventually beat the demo - the devs told me I was the first person to beat it.

    The full version just came out on Steam - I'd recommend taking a look. It's a bit janky and not for everybody, but it does something unique that really clicked for me.

    Thermodynamics, specifically refrigeration cycles.

    Its probably my autism showing but the fact that we can just move funny fluid around and make heat move is absolutely fascinating. I can spend a lot of time making theoretical refrigeration cycles with different fluids, thermoelectrics, heat capacities, repurposing car junkyard AC systems, etc.

    Millions of people do it for work, sure. I doubt any of them are "into it".

    I touch r134a the most in my day to day life, cuz i fix a lot of people's car AC... But I have a soft spot for propane (R290) or propane/butane blends. Yes it's flammable to a degree but it's naturally provided, cheap as hell, zero ozone depletion and very low GWP. It has usable pressure/temperature curves that are easy for compressors to handle and can produce temperatures as low as -30C.

    I've refilled old farm trucks with propane from a BBQ can and gotten good AC out of them. It's kind of cool.

    I have a lot of obscure interests, but not as obscure as yours.

    • Finding former Pizza Huts in North America. It's just such an iconic building design. There's a documentary out now on them, but I've been fascinated for almost a decade now.

    Ah, well the good thing is its pretty easy to set up. Most nodes are already flashed with recent enough firmware, so you just attach antennas, connect to your phone, do some quick setup for your region and go for a walk.

    Then you realize you want a node that stays at home.

    Then you want one on your car.

    And reachable from work.

    Then you see that hill in the distance and think "that'd be a good spot".

    Then you see the mountain on the horizon and wonder if you could hit a node up there.

    Then all of a sudden you realize you've single handedly set up the infrastructure for your part of the state and are out more cash money than you told your partner and need a side hustle to afford to finish the second mesh you're building out.

    I’ve been thinking of setting up a node at my local ski area, both for others to use, but also to make custom timing equipment that can send start and finish messages to the timing computer and keep us from having to haul wires up icy race courses all winter.

    I’ve never actually set one up or used one yet though, so it’s probably a few years off.

    I've seen a bunch of old Pizza huts turned into Chinese food restaurants and I saw two that became small used car offices. They are always so easy to pick out. I legit loved old Pizza Huts with the sit down pacman machines being a common fixture when I was a kid.

    Well.. I'm using an instance that has 10 active users according to https://piefed.fediverse.observer/list :)

    I wanted to move from Lemmy to PieFed, because its development is faster than that of Lemmy's and because its maintainers have values I have nothing against and because I want to help a cool project grow.

    And then I had a bunch of criteria that I wanted my instance to fulfill, and piefed.ee was the only PieFed instance that fulfilled all of my wishes. So, now I'm apparently one out of ten :)

    Whenever I'm going abroad within Europe, for a bit over month before that, I start buying stuff only with banknotes. I put all of the coins made in Finland or (other) Baltic countries in a separate pocket and then make sure to use those during my travel.

    It feels nice that people get to see coins that they don't see that often. And at the same time, I'm increasing the relative amount of non-Finnish coins in Finland, which I also think is good, as that helps people here notice that there's more to the EU than just Finland :)

    I would guess it's unlikely that all that many other people do the same.

    I'm really, really into what I can only call technological bootstrapping. Like, we started out on this planet with nothing, and then built everything. How did that happen? Primitive tech is another name, but the emphasis is usually on the very first stages.

    That itself has gotten me into obscure things like metrology, greenwood working and small-scale semiconductor fabrication.

    Wait, I work in cleanrooms professionally. Fabricating my own semiconductors at home always seemed like a cool idea, but really out of reach. I kind of always wanted to keep old machines from the labs I worked at, but with such expensive things they never threw anything away (of course)!

    Isn't it prohibitively expensive and/or noisy? What type of projects do you do?

    Have you seen the Sam Zeloof videos? He's the main person I've seen actually build a chip in a garage.

    He buys his wafers, which is critical. Given a hot furnace you could refine your own metallurgical silicon in a crucible, but cleaning it will be a whole thing. The machine needed would probably be based on spinning band distillation, which you could make in a pre-existing machine shop. To avoid toxic gases and explosion hazards - which are the two things chemists have told me not to mess with - you'd want to use SiCl4, which is a bit different from the standard approach which uses hydrogenated species. The Siemens process back to silicon and monocrystalline casting is all that's left, and I wonder if they could be combined in a step if scalability isn't a concern.

    What type of projects do you do?

    If only I had space for a workshop, so it's all theoretical ATM.

    Which machines are noisy? Polishers?

    Ah, not to worry, even professionally it's very common to buy your wafers. I am on mobile data right now so I'll check out those videos later!

    Basically, every single machine that needs a vacuum chamber - so almost all non-wet processes, like physical/chemical vapor deposition, reactive ion etching, scanning electron microscopy (although a good optical microscope will do if you're not at the nano scale... Which is almost certainly the case if you're doing things at home).

    Honestly maybe I'm just too used to the lab setting and am underestimating how much you can actually do without vacuum processing. I'll take a look later: this all looked so out of the reach of an ordinary person that I never even considered following content creators who do this. Thank you!

    High vacuums are tricky. The first high vacuums were achieved with mercury-based Sprengel pumps, but mercury isn't available everywhere. Maybe you could make a small, slow turbomolecular pump work if it was mandatory (it's all about the bearing) but it seems anything that needs sealing is going to struggle without either that or a massive petrochemical industry to supply the needed high-quality synthetic oils. If you're doing technology all over again, I'd skip the vacuum tubes stage because of this.

    If you can get away with a low vacuum, a piston-type pump with castor oil as the sealant will do. It seems like a low vacuum would work for at least some kinds of VD. Maybe you can help clear it up a bit.

    (although a good optical microscope will do if you’re not at the nano scale… Which is almost certainly the case if you’re doing things at home).

    1 micron features is as ambitious as I've bothered to think about. For basic computing, like to run a CNC machine, that should do.

    That's cool! Can you recommend any resources on this? I've thought a lot about this sort of thing. I'm guessing semiconductor fabrication requires a lot of complex upstream tasks and isn't the sort of thing that's feasible at home. Would love to be wrong!

    "The Book", is a book that uses illustrations to explain how to recreate civilization. Dunno if it is good. That said, you can also try "How Things Work", which explains the workings of many inventions, with many wooly mammoths interspersed throughout.

    Man, that's one of the books I most distinctly remember from my childhood. I've looked into getting a copy, but a quick look indicates the original edition is actually pretty pricey now, probably because I'm not the only one.

    I think I can draw a pretty direct line between reading the logic gates section of it, and the CPU design project I still have going semi-separately from the bootstrapping. Although it's possible I learned about gates somewhere else first.

    Depends where you're starting. If it's sticks and stones, yeah, you're going to spend a lot of time building up. Even getting to the prerequisites for the Gingery-esque machine shop will be a trick, and you definitely need machining first.

    Sam Zeloof is the guy that actually did the semiconductors bit. He makes a transistor in the linked video series starting with a commercial wafer, some basic chemicals, a spinning piece of tape and an electric furnace. I read papers and just Wikipedia to get ideas for the parts he doesn't cover. The standard ways of doing things are heavily constrained by scalability, which as an artisan you don't care about, but will breeze past other things you really do, like ability to work in a small space. And, if you're starting from scratch, using only common, locally available elements.

    This sounds like the entire premise behind the manga/anime Dr. Stone.

    All humans on earth get turned to stone, and a young scientific supergenius teaches survivors how to essentially restart civilization from scratch.

    It's an absolute joy to watch. Maybe you'd dig it? :D
