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.

I'm not crazy old, but I'm old enough that the supermarket I went to as a kid had these at all the checkout aisles and the cashiers would use them to send cheques/reciepts/ whatever.

It was awesome to see.

Big hospitals still have them to send medications and random lightweight stuff around the complex. My wife has worked in two large hospitals that had pretty extensive tube systems, used especially with pharmacy.

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.

Edit: bothered to look it up

I know of a hospital where the local university sends tracers with F-18 for PET scans in much the same way. Half-life of 110 minutes.

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:

My kid's car is like this. I've been calling it retro-futuristic, which I think is a pretty apt description.

[–] Chaos0f7ife@lemmy.world 2 points 3 weeks ago

CD players/walkmans. Wearing your headphones and jamming out music on your CD player makes you 10X cooler in my eyes.

I was thinking the other day how much cooler flap displays at stations and airports were compared to modern displays.

Such a nice interface between computer control and a purely mechanical display. Watching them update, flipping through all the variables to land on the right one, and then clearing was so cool.

I miss the noise they made too. Haven’t seen one for like 20 years now.

Electromechanical stuff. Like old jukeboxes, pinball machines or anything else that required programming before the widespread use of microcontrollers.

Some people have already mentioned stuff akin to this, like the mechanical govenor, or the post abt THIS MUSEUM IS NOT OBSOLETE, but it really deserves its own thread.

Technology Connections on YouTube has made some great videos about devices like that.

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.

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)

[–] WoodScientist@lemmy.world 1 points 2 months ago

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!

Electric guitars. They sounded better. Newer ones just sound louder.

[–] itstoowet@lemmy.world 0 points 2 months ago (1 children)

They also feel...worse? Jumbo frets, thick coats of polyurethane, cheap pickguards, plastic pickup covers, etc — yuck.

I've been buying weirdo vintage guitars (teisco, musima) and they feel way better in my hands. The pickups are usually pretty low output, yeah, but the cleans sound so so good.

[–] IchNichtenLichten@lemmy.world -1 points 2 months ago (1 children)

Looks awesome! I'm guessing the body is about 1" thick?

[–] itstoowet@lemmy.world 0 points 2 months ago (1 children)

Well that one is a baritone (26.5" or 27" scale) but still pretty thin (about as thick as the typical strat) and ergonomic.

My other guitar, a 1960s teisco, is one of the lightest guitars I've ever owned:

I'm gonna modify this one though and put a tuneomatic on here, the intonation is quite terrible.

That bridge looks like it's just a flat metal bar, yeah that's gonna cause problems.
