I'm sorry if this is not the best place for this, I couldn't think of anywhere better to ask about it
the reason most of these people are youtubers is because I went through my youtube subscriptions for ideas
edit: I've just realized I forgot to add rule to the title but I don't know how to fit it in there with it looking not bad
Posy has many videos along the lines of technology connections with incredible macro footage as well as lots of other random interesting stuff.
mitxela for well documented high quality projects blending mechanical and electrical engineering.
The Tim Traveller is basically Tom Scott if only covering strange historical things. And unlike Tom Scott he's still making videos.
Cathode Ray Dude does a mix of long form content like technology connections, but focusing on relatively modern computers.
I LOVE posy, just a dude talking about whatever catches his fancy and making beautiful videos about them.
