Youtube is full of videos like that. A few sample excellent channels: https://www.youtube.com/@animagraffs https://www.youtube.com/@engineerguyvideo https://www.youtube.com/@Lesics/videos The problem is more that they are drowned under the volume of content available.

I'll recommend a couple of other channels: - Old Royal Navy instruction manuals and documentaries: https://www.youtube.com/@davidbober7035 My favorite is Hands To Flying Stations (1975): https://youtu.be/cALccuPShQc - Historic films and clips, mostly focused on workplace safety: https://www.youtube.com/@markdcatlin My favorite is NASA's Toxic Propellant Hazards: https://www.youtube.com/watch?v=ND2TeNfcmKA

I'd like to throw in a recommendation for Huygens Optics: https://www.youtube.com/@HuygensOptics

Everything you ever wanted to know (and more) about light and lenses, explained in a way that's totally comprehensible if you learned electricity and magnetism physics in college.

Have you seen Technology Connections on YouTube?

A criticism I have with not just Technology Connections but plenty of similar channels is that each video seems to just be whatever they thought of doing next. I would love something of the same caliber of quality but with a blueprint for an entire series that would cover the compete gamut of a subject. A popular YouTuber mentioned on HN, and deservedly so, is Ben Eater. His series on building a 6502 computer on a br…

That series Ben Eater did was really fantastic. Between following along in Logisim and trying a more ambitious design afterwards, it was the most fun I've had in a long time.

The obvious solution is to actually have librarians correctly classify the videos. DDS focuses on the nature of the work itself, not on the keywords or spam in the content. Librarians understand how to class all kinds of works, and it should be relatively simple to build a DDS/MDS index (Melville Decimal System since it's open, see https://librarything.com/mds ) for YouTube videos. Just like with books, disagreement…

> The obvious solution is to actually have librarians correctly classify the videos Which videos? The 500 hours of video uploaded every minute?

There is already auto captioning done by YouTube. It would be trivial to plug an ai that generates tags and classify each videos based on the whole content. I am sure they already do that.

Yes - he's one of the very best! I loved his 3 part series on making a reflector telescope from a single chunk of glass.

Fax machines go way back to the 1800s, before phones, surprisingly old! Another classic is Tim Hunkin’s secret life of the fax machine https://youtu.be/yuUyt9RG7pk which features a clip from the video in TFA.

Pantelegraph -> wirephoto / radiofax / teleautograph -> telex / weatherfax -> fax

Older even than the Pony Express.

Western Union predates the Pony Express by about 10 years, which operated for only 18 months. It was the Webvan and WU was the Amazon.

For a slightly later version of this: My most popular YouTube upload is the telecopier scene from Bullitt, where you can see the police use the latest and greatest "fax" technology of 1968. I uploaded the video without almost no information, but in an surprising twist, a lot of the youtube comments are actually pretty informative. https://www.youtube.com/watch?v=nQGAaCSFlJI

There’s a similar device used to transmit the first recovered victim’s fingerprints from the funeral parlor to FBI field offices in Silence of the Lambs.
