I don’t mean BETTER. That’s a different conversation. I mean cooler.

An old CRT display was literally a small scale particle accelerator, firing angry electron beams at light speed towards the viewers, bent by an electromagnet that alternates at an ultra high frequency, stopped by a rounded rectangle of glowing phosphors.

If a CRT goes bad it can actually make people sick.

That’s just. Conceptually a lot COOLER than a modern LED panel, which really is just a bajillion very tiny lightbulbs.

    Pneumatic tubes were way, way cooler than email.

    Of course, you could only use them to send a message to someone in the same office building, so the comparison isn’t perfect… but you know what I mean.

        Tom Scott does a youtube video about one in Canada (IIRC) where they send radioactive medicine from the lab a down the road to a hospital due to the half life of the medication making traditional transport (ie vehicles) impractical.

        The two major hospitals, relatively near me, use a combination of tubes, and robots, to dispense medications. One is working on completely robotic food service, and has completely robotic floor cleaning/polishing. Both, also, have robots that do the basic landscaping maintenance, like mowing/edging. There is more, it is interesting to walk around and see all these infrastructure systems work. Feels, at least partially, like the promised future of sci-fi.

      Before ATMs, bank drive-throughs (the ones with multiple lanes for cars) had pneumatic tubes to send cash and checks to the bank teller, or receive cash.

    I like the look of vacuum-fluorescent displays (VFDs) – a high-contrast display with a black background, solid color areas. Enough brightness to cause some haloing spilling over into the blackness if you were looking at it. Led to a particular design style adapted to the technology, was very “high-tech” in maybe the 1980s.

    OLEDs have high contrast, and I suppose you could probably replicate the look, but I doubt that the style will come back.

    Cars used to be cool. Every car company had some kind of sporty car, a couple cheap cars, a big luxury sedan and, a while ago, a station wagon.

    Now every car is an SUV or CUV. Sedans are getting phased out. Cool sports cars don’t make money so they don’t make them. People don’t buy station wagons so they don’t make them. And they’re pushing big, angry trucks on everyone.

      I think that some of that is fuel efficiency requirements forcing convergence.

      The sedan thing weirded me out too – I mean, when I think of a “car”, I think of a sedan – but as I understand from reading, that related to people wanting larger maximum cargo space in the car, like if they had to shove a piece of furniture or something in it. I’m in the sedan camp – in the very rare case that I need to move something really large, I’m just gonna U-Haul it. But I can at least understand the concern people have.

      The truck and generally-large vehicle thing, I think, related to a combination of:

      • The chicken tax. American auto manufacturers have a 25% protective tariff covering the “light truck” class, making it much more profitable for domestic sales.

      • Fuel efficiency exemptions granted that class (which I suspect may have something to do with regulations resulting from lobbying from said manufacturers and them having incentives surrounding the above chicken tax).

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

        CAFE standards signaled the end of the traditional long station wagon, but Chrysler CEO Lee Iacocca developed the idea of marketing the minivan as a station wagon alternative, while certifying it in the separate truck category to allow compliance with less-strict CAFE standards. Eventually, this same idea led to the promotion of the SUV.[106][107]

        The definitions for cars and trucks are not the same for fuel economy and emission standards. For example, a Chrysler PT Cruiser was defined as a car for emissions purposes and a truck for fuel economy purposes.[2] Under then light truck fuel economy rules, the PT Cruiser had have a lower fuel economy target (28.05 mpg beginning in 2011) than it would if it were classified as a passenger car.

      • High American towing requirements. That is, American vehicles have far more restrictive towing requirements than in most other countries – you need a larger vehicle to legally tow a given load than in many other countries. I suspect that the regulations may also have something to do with American automakers lobbying for protective regulation; it pushes American consumers to buy from that protected class of vehicles.

      Long story short – I think that you can probably chalk a lot of that up to rent-seeking out of Detroit.

      I’d take it even further: Cars used to be cool - in the 50s to late 60s. Modern cars look so bloody bland in comparison. I’m sure there were duds as well, but the models that show up in period pieces look way cooler than anything we have today.

        I’d say a hatchback is a sedan with the trunk/boot removed, while a station wagon has the trunk/boot extended to the roofline. Hatchbacks would end up shorter than the sedan or wagon version of cars.

      It’s because people want a big boot. In Europe hatchbacks/cross overs are favored over sedans for that reason. And people just don’t like the look of a station wagon/estate car. Only the luxury brands still make sedans.

    Disney lost their old camera tech used to make a “yellow screen” with sodium vapor lights.

    It’s actually better than a green screen because the yellow light is so specific that even if you remove that particular frequency of light, everything else still looks fine. You can do all sorts of things that would normally be very difficult to pull off with any of our green screen tech (like drinking water in a clear bottle or wearing a rainbow dress).

      Considering LEDs are so good at producing a very tight wavelength, I wonder if this could be replicated with more energy efficient lamps.

      Or if non visible spectrum lights can be used to make similar alpha channel masks that don’t affect lighting the scene.

        A laser, maybe, but definitely not LEDs. Vapor/gas lamps produce the narrowest frequency bands possible, because it comes from very well defined atomic transitions (Hz range). LEDs produce frequency bands with widths in the GHz/THz range, while semiconductor lasers can maybe reach KHz if they are really good. So, unfortunately, for this type of applications, vapor lamps would probably still be needed.

        Source: I work with lasers and spectroscopy.

        Edit: very good idea about using non-visible light!

          Is there some filter that you could put up over the LEDs that would block everything but a very narrow frequency of light?

            Well, one possibility is using something known as Fabry-Perot filter. It allows an extremely narrow frequency to pass, due to multiple reflections and interferences inside the material. Put the light source material within this filter, and you get a laser. That’s essentially the main difference between a led and a semiconductor laser. The filter makes only a narrow band of the emission be “stuck” there, creating a feedback effect that eventually tends to infinity, and a good chunk of that power passes through the filter reflectors, which are intentionally not perfect.

            Other than that, I don’t think there is a filter that could be as narrow as the line emission from vapor lamps. Maybe using metamaterials, but a laser would be so much cheaper and easier. A vapor laser would certainly get the job done, but they are large and hard to maintain.

    Oh man…I have an entire ten page paper on the go about this topic and it just keeps growing. One day I’ll publish it in a blog or something, but for now it’s just me vomiting up my thoughts about mass market manufacturing and the loss of zeitgeist.

    The examples that I always use are a) Camera Lenses, b) Typewriters, and c) watches.

    Mechanical things age individually, developing a sort of Kami, or personality of their own. Camera lenses wear out differently, develop lens bokehs that are unique. Their apertures breath differently as they age No two old mechanical camera lenses are quite the same. Similarly to typewriters; usage creates individual characteristics, so much so that law enforcement can pinpoint a particular typewriter used in a ransom note.

    It’s something that we’ve lost in a mass produced world. And to me, that’s a loss of unimaginable proportions.

    Consider a pocket watch from the civil war, passed down from generation to generation because it was special both in craftsmanship and in connotation. Who the hell is passing their Apple Watch down from generation to generation? No one…because it’s just plastic and metal junk in two years. Or buying a table from Ikea versus buying one made bespoke by your neighbour down the street who wood works in his garage. Which of those is worthy of being an heirloom?

    If our things are in part what informs the future of our role in the zeitgeist, what do we have except for mounds of plastic scrap.

          I’ve got a drawer that has a stack of my old phones and devices in it. Among them is the CD MP3 player I’ve had since high school. It’s 24 years old, made entirely of plastic, it followed me all the way through high school and part of the way through college, and it’s in perfect working condition and bears only light scuffs. It might be my midlife crisis coming on but I’m tempted to start using the thing again instead of my smart phone. My PC tower has a 5 1/4" bay, I’m tempted to install an optical drive in it.

    Any mechanical regulation process that used to be handled by actual machine parts. Think of the centrifugal governor, this beautiful and elegant mechanical device just for regulating the speed of a steam engine. Sure, a computer chip could do it a lot better today, and we’re not even building steam engines quite like those anymore. But still, mechanically controlled things are just genuinely a lot cooler.

    Or hell, even for computing, take a look at the elaborate mechanical computers that were used to calculate firing solutions on old battleships. Again, silicon computers perform objectively better in nearly every way, but there’s something objectively cool about solving an set of equations on an elaborate arrangement of clockwork.

        He’s not talking about punch card programming, that’s way more advanced and requires a Turing machine, what he’s talking about is computers as the term was using before what you would think as a computer existed.

        The example in the video is for the computer on a cannon in a battleship. If there wasn’t a computer you would need to adjust the angle and height of the cannon, but that’s not something a human can know, what humans can know is angle to the ship and the distance to it, so instead you put two inputs where a human inputs that and you translate that into angle/height. Now those two would be very straightforward, essentially you just rename the height crank to distance. But this computer is a lot more complex, because wind, speed, etc can affect the shoot, so you have cranks for all of that, and internally they combine into a final output of angle/height to the cannon.

      To add, there is something about those old 40s and 50s era technical films like you linked that is just so… I don’t what exactly it is, but I find them fascinating and genuinely informative, even though they are explaining tech that is decades obsolete.

      It’s pretty awesome that they are still available 70+ years later in excellent quality!

      Someone showed me a record turntable with what must have been a centrifugal governor! What an ingenious device. (I got the impression from him this was unusual for a turntable, at least…)

        I was under the impression that all wind-up turntables (I.e.: from the shellac records and steel needles and mechanical reproducers era) were using mechanical governors

        Maybe I’m wrong though.

      H model C-130s, the ones with the 4 square blade props? The engines and props are mechanically governed. There are electronic corrections applied, but the core of the systems are purely mechanical. Still flying.

      Centrifugal governors are possibly one of the origins of the phrase “balls out” or “balls to the wall” (although many say “balls to the wall” has to do with the ball-shaped handles on old aircraft throttle levers)

      Also somewhat similar to governors are centrifugal switches, which are used in just about anything with an electric motor to disconnect the motor from a capacitor which gives the motor a little extra juice to get it going (I like this video for an explanation of how they work)

        I didn’t know that was a thing. Thanks! I’m honestly surprised some MBA bean counter hasn’t replaced those with a chip of some sort by now. Really cool!

    Bicycle shifters.

    The first iteration that could be operated without stopping was the Campagnolo Cambio Corsa.
    To shift, you had to reach behind you, where there were 2 levers.

    The first one loosened the rear axle so it could move freely back and forth in the dropouts.
    The second one had an eyelet you could use to move the chain sideways.
    You put the chain on a different cog, and the rear wheel jumped forward or back due to the changed chain length.
    Then you tightened the rear axle again.

    It’s terrifyingly beautiful:

    A lot of older tech had a way more interesting silhouette. You can see this clearly in how many objects live on in icon form. We still often use handset phones, magnifying glasses, gears, or the infamous floppy disk save icon. I think the staying power of these really comes from how ephemeral and formless digital tech can be.

      Reminds me of the device icons in Microsoft Intune.

      Android is represented by a rounded rectangle. Linux is a rounded rectangle, but yellow. iOS is, you guessed it, a rounded rectangle, but black.

      Windows, however, is a nice flat-screen monitor (read: a rounded rectangle on a stick)
