These huge mechanical clocks in church towers.

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.

A nixie tube is a bunch of tiny lightbulbs shaped into numbers in a single pack with different pins each turning on a number.

Clearly the modern number display is better in many ways, but you were asking for coolness.

Lighthouses.

Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and the advent of much cheaper, more sophisticated, and more effective electronic navigational systems.

They were quite important for a long time. We used them for thousands of years, and they're often unique in form, iconic. And they're a good subject for photos and paintings, and I think that the light effect from them is neat. Lots of books and such using them, like ones on remote rocks, to get an isolated setting ("the lone lighthouse keeper").

But the past few decades of technological advancement have probably closed the end of their era.

I could mention toasters or pinball machines or flickering light bulbs or unusual people movers, but instead I'll save some time and just link the whole obligatory channel: https://www.youtube.com/@TechnologyConnections

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.

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.

Portable music players.

They were the coolest when they used minidiscs.

Also, waving a magnet around a crt was fun.

Older forms of computer RAM.

Before integrated circuits, we had core memory which was a grid of wires and at each intersection was a little magnetic donut that held a single 1 or 0.

Before that they had delay line memory, where they used vibrations traveling down a long tube of mercury, and more bits meant a longer tube to store a longer wave train.

The Gameboy.

The switch is neat, but it's too large.

Horsehide bomber jackets of the sort worn in WW2.

We can make cheaper and lighter synthetic materials. But I like the look that leather jackets acquire with wear over time (and particularly horsehide, which is less-available today than cowhide, as we don't have many horses around any more).

They aren't gone -- it's still possible to obtain them. But in 2024, they're really limited to people going out of their way to get them.

Interchangeable automotive/bicycle parts.

Or for that matter, interchangeable anything parts.

Both cooler and better at the same time. Interchangeable parts made it easier to both customize and repair your own stuff..

Carburetors are pretty fuckin cool.
The concept seems simple: utilize the vacuum from the engine to pull in fuel. But they're extremely complicated with all the tiny orifices and passageways to perfect the amount of fuel going into the engine at different points.

Unrelated sidenote: i got deja vu writing this comment. Interesting.
