Anyone designing their own high-speed circuitry out here?

    I think no one likes me the second time around either. LET sucks, will go hang around with EE nerds. And by the way, I WILL build a motherboard, eventually.

    Farewell,

    Yes, your basic sensors can be made as JLCPCB for dollars, it's designing that that takes the time and effort. But surely you know JLCPCB isn't equipped to make server motherboards due to part availability and complexity.

    I don't know who JLCPCB is so I have no idea what their capabilities are.

    They are a relatively big and after dumping their (open and hidden) ads all over the place quite well known "go-to" place to get boards made. But their main strength seems to be that they are very cheap (but IMO not the right place to go to for quality and/or a bit more sophisticated boards).

    TL;DR (IMO) you didn't miss anything of relevance.

    So it is otus afterall

    Does anyone have snickers here? @FAT32 do you have one? I gave mine to my dog

    Ah, good times. Remember going all out on these people. Got that MEDIUM warning for that. Nurturing experience for sure. Thanks @khadhafi1083.

    I will cover this in my next post in
    https://lowendtalk.com/discussion/198755/my-journey-to-a-software-as-a-service-deployment-platform-aka-my-journey-to-5k-monthly#latest
    Nothing serious, just a brief "That was really useful" note.

    So don't forget to check on it once in a while.

    Everybody thinks that it would cost so much more in small quantities but we do it. Not a lot of motherboards but we design and build our own KVMs and environmental sensors. (plus a few other things)

    Uhm, KVMs and env. sensors (vs. modern mainboards) is like saying "I sometimes snorkel very near the cost, surely I also can salvage and repair a sunken warship in 3000m depth".

    You can get the boards stamped in China for a few cents each in quantities of 20-30.

    Stamped? uhum. PCBs are not stamped, they are milled - especially in the quantities we're talking about here.

    Our remote sensors, temp, humidity, pressure. Cost us about $3 each to build. Our KVMoIP modules we've developed cost us about $13... and that's with and expensive buck converter. We build them 10-20 at a time.

    "expensive buck converter"? Uhum. fyi: buck converters are dirt cheap.

    Anyway, while I doubt the depth of your knowledge and expertise in electronics I'm not here to belittle you. You design and use your own KVMs and sensors? Great, and possibly a smart move. Kudos.

    A modern mainboard however is an entirely different league, that's for real EE professionals with high-end equipment, years and years of expertise, and many millions in their back. Their logic analyzers alone almost certainly cost more than your house ...

    Btw: Why design a mainboard from start? There is plenty of things (and components) on existing mainboard that are compromises, often ugly ones, like e.g. cheap crapacitors, lines with "just about good enough" questionable routing, aso, aso. Hell, even just improving "lowly" power supplies might save you quite some money (if you run many).

    In other words: there are plenty interesting (for an EE) things on or around a modern mainboard worth attention and some work if one is so inclined.

    I have bad news for you: compared to EE nerds the LET people here are really nice and patient...

    Will do. It's WIP, I need to change some things in there anyways.

  • Philosophically the world is kind of fucked long term if the bootstrapping necessary to create a server motherboard is beyond the reach of a small team/budget and/or a lifetime of learning

    It isn't. This guy just isn't an EE.

    Prototyping is expensive, full stop. It's mass production that gets the price down and even then, it's small margins.

    Exactly, it practically creates this really annoying barrier. You start to think you are powerless and that you can't even create a motherboard of your own. Don't worry, it will be changing.

    Learn to dream and get your dreams to become realities. Don't shut something down, just because you can't do it. You are right, I don't like labels, so I don't try to label myself as "something", I just am, I am above this bs.

    Small teams can and currently do it. They don't do it for low volume. Go look at the price of a component for 10. Now look at the price for a million.

    Motherboard is generic term and simple motherboards are made daily. But the issue is the "server motherboard" where you need signal integrity for the PCIe lanes and RAM and that means serious test equipment from Agilent or Rohde & Schwarz. It also means you know wtf you're doing, that takes experience.

    That being said, CAD design is an area ripe for AI. Giving it some datasheets and telling it to make the reference design will cut down on tons of hours. Also, for auto-routing algorithms. I have yet to meet an engineer who made substantial use of the built in auto routing capabilities (an instructor I had 25 years ago said the best ones start at 100k).

    Dreaming doesn't give you an education or skills. What kind of silly shit are you going on about? People with 4 year degrees don't design server motherboards right out of school. And decent CAD tools aren't free. If you were in fact an Electrical Engineer, you sure as fuck would use that label.

    Learn to dream. I didn’t read your essay, but I know you tried to be offensive. Y’all talk too much without consequences. Go study, baby boy—I’m not wasting time on internet armchair quarterbacks.
