- Alpha Phoenix, a combination of physics and simulation. Thermite art, optimizing gerrymandering, growing large single crystal ice, practical demonstration of the speed of electricity, etc. https://m.youtube.com/c/AlphaPhoenixChannel
- Huygens Optics[1] : Retired Philips' research scientist that worked on OLED development and makes highly detailed videos on different subjects, all relating to light (eg: Making optical logic gates using interference, DIY photolithography, Making a Mirror with a Variable Surface Shape).
- Marco Reps[2] : German guy doing electronics videos, usually about precision/exotic instruments (eg building a CERN open source 8.5 digits voltmeter, High speed thermal camera, Detecting cosmic rays with a raspberry pi). Has the same type of humour as Tom7
- Styropyro[3] : Laser hacker, creating stupidely powerful lasers (think 100W continous handeled laser)
- CuriousMarc[4] : Guy working on restoring old 60-80s electronic/computer equipment. Is most known for his ~25 part series on restoring the Apollo Guidance Computer. As a sidenote, Ken Shirriff, which writes die reverse-engineering articles at righto.com (which frequently pops up on HN), frequently appears in his videos.
- Scanlime[5] : Highly detailed reverse-engineering/hacking/explanations videos. Sadly she isn't that much active anymore.
- der8auer EN [6] : German guy doing mostly videos about CPUs/motherboards (think insane overclocking, etc). However he has a few hugely detailed gems, such as demonstrating how 7nm chips are troubleshooted, by probing them under a SEM[7]. Also as a sidenote, he shoots all of his videos twice, once in german and once in english, instead of just dubbing over them, which is an insane dedication imo.
- Applied Science [8] : Relatively well known channel, describing various experiments that he does in his home shop, like : Building a LCD, Silicon wafer etching, DIY mass spectrometer, etc.
- Cathode Ray Dude [9] : In-depth technical videos about mostly vintage video gear, which at first glance you wouldn't typically find interesting. Same kind of nerdy humour as Tom7
- Technology Connections [10] : Hard to describe the style, mostly videos about technical subjects, going much more in depth than you though was possible, with a really nerdy/dry humour.
I might have missed some, but those are the main ones that comes to mind.

To the contrary, it is very easy to describe: it is an entire channel dedicated to the latent heat of water.
(For those who haven't seen it, he goes into refrigeration and heat exchangers a lot and this topic constantly comes up, becoming a running joke)
The Channel: https://www.youtube.com/c/TechTimeTraveller/videos
Videos mostly about retro computers and companies from the 70s and onwards.
It's amazing how high quality the videos are and how much effort this guy puts into them even thjough he only got about 2k views per video up until the latest vid. Seems the persistence finally payed off.
I always get a kick of delay line memory. The Mercury memory also mentioned on the Wikipedia page, which I've seen in person (but sadly not in operation) at the Computer History Museum, is literally sound waves in liquid metal. How much cooler than that can memory get...
Though the nearby (and at their time quite popular) "storage tubes" that were effectively CRT screens with very long image persistence are cool, too, and one of the fewer dynamic storage technologies where you can see the individual bits. The actual ones, not just a representation: https://en.wikipedia.org/wiki/Williams_tube

If we are willing to run an authoritative DNS server, we can simply find open DNS resolvers, then query TXT records from our own domain, with a suitably near-infinite TTL. It's free real estate^H^H^H^H^H^H^H^H^H^H^H storage.
Perhaps that's not hard enough for harder drives. We can do the same thing, except use NX records from an arbitrary domain as the storage medium. We can query e.g. a01234-somedatahere.example.com, which will produce an NX record in the resolving DNS server. We can later "read" this data by issuing the same query and seeing that the TTL is not the original NX TTL of example.com. This is a destructive read process, so we will need to immediately write whatever we read, but suitably altered to avoid a collision, e.g. a01235-somedatahere.example.com.
However, I'm not sure it's fair to talk about "limiting ourselves to ping", as I'd argue that there are vastly more generic hosts replying to ICMP echo than there are open DNS resolvers (which I know includes all openly available nameservers). I believe the video also has shown that the number of pingable hosts pretty much approaches the number of hosts with an external IPv4 in the first place, at least the map he's shown looked lighter than dark to me.
* subject drive to 100t press (it got thinner!)
* immerse drive in acid (little change) or base (drive dissolves!)
* subject drive to industrial guillotine
* warm drive with oxy torch
* drop from 300 ft tower (little change)
and so on. All good fun.
While I can’t say I understand everything that’s going on, I am simply amazed by the creators talent and knowledge.
Captain Disillusion is definitely up there. His Flight of the Navigator video is one of the most remarkable things I've ever seen on the internet.
Edit: spelling.
This is a weird way of implementing one, but it's using multiple ICMP queries, each acting as their own delay line.
And also infect all my peers.
>6 Conclusion
>In this paper, we decided that sometimes it’s more fun to do things the hard way, and then did so. Using several different techniques and some needless digressions, we created block devices that could support small filesystems, which then could host a fitting file. Each filesystem was bad when considered as a regular hard drive, but good when considered as a Harder Drive. We also compared these drives to the most popular cryptocurrency. The idea was to make the point that cryptocurrency is so egregiously bad that it resembles a “SIGBOVIK joke gone wrong” more than something one would make on purpose. This part may not have been as fun.
