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.
Video game consoles.
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.

EDIT: A few more car dashboards using similar style:

Some other devices using VFDs:
As a kid, I had this tabletop video game called “Dracula” that featured a multicolor VFD display. I loved that game.

Oh what kind of car? I’d love for this style to come back for a bit.

Newer, but I quite like the gentle amber LCD (not LED) displays of my car. At night it’s bright enough and sharp enough without being visually loud. I wish more of these displays were still being made, I’d love to use them in car-centric Arduino projects and data displays that would be consulted at night or that sort of thing.
I always ask my friends “How the fuck do you live like this?” when I hop into a car and the music UI is a garish color searing itself into my retinas permanently.
Thankfully, advertising companies have identified this marginal comfort I find in the warm interior lighting of my car and have proceeded to mount insultingly blinding screens all over the city.
The city being the midrise urban sprawl north of Beirut. What do you mean regulations on brightness habibi? You think you live in Paris? Imagine this: half the street is unlit because the power is out, but the advertising company’s invasive bullshit budget™ has enough foreign cash to burn to keep generators running all night for these shitty ads. Gotta beam an extra few kilowatts of photons straight into this sleepy driver’s eyeballs while they operate a motor vehicle, on a highway that a lot of people cross by foot. There’s a special on fish at the fancy supermarket, how will I live without that knowledge?
Thankfully, the “state” of Israel has identified that the civilian structures of Lebanon mildly inconvenienced me, and has proceeded toNewer, but I quite like the gentle amber LCD (not LED) displays of my car. At night it’s bright enough and sharp enough without being visually loud. I wish more of these displays were still being made, I’d love to use them in car-centric Arduino projects and data displays that would be consulted at night or that sort of thing.
Not sure if you mean VFDs or amber LCDs, but Matrix Orbital sells both sorts in small quantities that you’d use in a project and can interface to a microcontroller – I was interested in them myself when looking for small VFDs, years back. They’re going to be segmented alphanumeric or grid displays, though, not things with physical custom display elements like those car dash things, but that’s kinda part and parcel of small-run stuff.

Just choose the “amber” option if it’s an amber LCD you want.
Can also get their displays via Mouser or Digikey.
That’s exactly the kind of display I’m talking about. Nice to see they’re still around.
The ones I have are all just grids, higher resolution than these but still comfortingly blocky. I’ve actually replaced the dash display recently since the original one got deep fried under the sun and lost all contrast when the weather was above 20°C.
Ah, good to hear it. They do (or did, and I assume still do) also have higher res displays.
Going back to an earlier bit in the conversation, where you were concerned about light sources in the car, I think that auto-dimming might also help (not just with VFDs, but the brightness of any in-car display). My car dash has the option to automatically set brightness based on ambient light levels (something that I wish my desktop computer monitor could do…part of “dark mode”'s benefit is a mitigation for devices that don’t do this). I don’t know if that was a thing back in the 1980s or so, when these display designs were popular.
I also kind of wonder if eye-tracking, which has come a long way, could be made reliable-enough and responsive-enough to toggle off displays if the car can detect that a user is looking somewhere away from them. Maybe be conservative, not with some critical displays, but stuff like the radio or clock or something. Eye tracking systems normally use the near-infrared, as I understand it, not visible light, so I’d think that you could theoretically do it in a darkened car without problems.
All of the car’s interior lighting (all in amber) does dim automatically when I drive under a bridge or into a tunnel, and automatically dims when I turn on the headlights. So some rudimentary dimming was implemented in 2000 when it was made. No clue where the sensor is though.
As someone who also likes VFDs, I’ve fully expected that they’d be extinct in new products by now thanks to cheap LCDs and OLED. But I find it awesome that they’re still hanging in there.
The phones with the internal hidden camera, I was sure it would be the future
https://www.91mobiles.com/list-of-phones/pop-up-camera-phones
I want this so I can be sure my phone isn’t sneaking a peek at my pooping face
Yes! And full screen with no bs punch-hole or pricey under-screen camera
My previous had this & I liked the privacy of it.
Sex toys and local multiplayer is a way better combination than cybersex and online matchmaking
I generally can’t be arsed with online multiplayer – Just as a concept.
But I made great memories with my cousins playing Wii/GameCube local multiplayer titles. Smash, Mario Kart, Sonic Adventure 2, et cetera.
I too like to play “Smash” with this guy’s cousins
But do you bond burger my sister?
I have never played a game with random strangers ever. But! My brother and sister both live hours away from me (and each other), and we keep in touch by playing online co-op games every week.
I have a group of friends that I have mostly kept in touch with by playing online games too.
So I agree with what I think you meant, but I’m very glad online multiplayer exists in some form.
I mean. All my friends who match my freak live 120Km+ away from me and so I have played online games with them.
But man it’s just not the same as the experience of snacks, a beat up sofa, crowding around a television, yelling at each other, yanno?
Agreed!
Who said you can’t do it anymore?
Still trying to find a way to get microtransactions in there, but I’ve already got horse armour, thanks
Tell that to the furries. Every furry I know that has a VRChat avatar feels more at home with a VR headset strapped to their face.
Furries and strap-ons seem to go hand in hand
A bunch of tiny lightbulbs that use twisted light and quantum mechanics to turn on or off.
There was a virus back in the day that could take advantage of old monitors. It would move a turkey around the screen and if you looked at it too long it would cause eye damage.
This is the kind of rumor that tech geeks spread at a sleepover.

Gotta need more data on that…
Car washes. All those pretty lights and water effects are now replaced with an instant transition.
CD players/walkmans. Wearing your headphones and jamming out music on your CD player makes you 10X cooler in my eyes.
This may not apply, (as I know I’m simply saying a commercial product got worse as it had revisions) but Jawbone’s first earbud/headset used a small rubber conductor to evaluate skull vibration for noise canceling ( and likely there was some ANC using incoming mic audio from external sources). They continued to include a rubber bumper but I think the device leaned more on incoming audio from mics rather than from the rubber bumper. The oldest device presented the best noise canceling even after 3 product changes. I used every version until they stopped making headsets. I miss my Jawbone. I still have my OG.
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).
This was a really cool video!
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.
Automatic watches and grandfather clocks. The way they kept track of time using only mechanical principles is crazy. How does my automatic watch recharge itself using only the movement from wearing it and keep accurate track of time. Grandfather clocks are cool because they’re so power efficient.
They are very cool indeed. And the fact that you can have a century old watch on your wrist and it’s just as useful as a modern one. In fact I’m wearing a watch from the 50s right now!

I still think ZIP drives are pretty cool. Or using cassette tapes of any kind for data other than video/audio. Hella wish I had a DAT drive still.
Zip drives still hold the most data of any media. Science may say otherwise, but science doesn’t usually come in bright neon colored sleeves.
I dunno about you, but I have a hankering for the mid-to-late-80s aesthetic, but specifically that taken into sci-fi. I’m talking Cowboy Bebop, Outlaw Star etc. 80s tech but… Future!
Everything’s so chunky and functional. It looks like you could hit it with a sledgehammer and it would still work!
Basically, BUTTONS! Gimme buttons, lots of big buttons! I want things that go click so I can be sure I’ve pressed them. I don’t want a tiddly little touchpanel for my washing machine, I want a button that goes CLACK when I press it!
That’s extremely the aesthetic I love about cyberpunk. Sure the story in Blade Runner is great but look at all the neat shit!
Ooh, rotary phone switches. This YouTube channel (THIS MUSEUM IS NOT OBSOLETE) has a bunch of videos on them. I can only imagine how a massive exchange full of them must have sounded. They’re so satisfyingly mechanical.

Sam is a treasure. I wonder if I would ever afford to travel, but I’d sure love to visit his museum.
