If you like NileRed I think you'd enjoy "Applied Science" and maybe "Cody's Lab". "Scrap Science" is pretty good, I felt bad for the guy after spending a year failing to make heavy water. I spent a couple years in a chemistry lab and that guy's "bathtub chemist" techniques make me cringe but it all generally works out, well, aside from failing to make heavy water. The "Hydraulic Press Channel" is very tangential but…
You've more or less posted my entire Youtube subscriptions list there! Applied Science (Ben Krasnow) is one of my favourites. Cody's fantastic too, for the backyard-science angle. I find Hydraulic Press a bit too "let's break stuff and laugh", but it's fun to watch and switch off for a few spare minutes. Same for Backyard Scientist ;) Post-Apocalyptic Inventor is good for my scrapyard-challenge-but-real fix. My real…
Yes the Hydraulic Press guys have a lot of "boom ha ha" content but they sometimes have more intellectual content such as "We're going to make homemade particle board out of sawdust" and I'm like, no, you're not, I know its way to complicated, but its fun to watch them try and be partially successful.
If you like retrocomputing, then "Moshix" channel will provide a couple hundred hours of mainframe content. The editing is slightly off, moves too slow during non-interactive content such as watching scripts run, and too fast during interactive content while hand editing JCL and typing sysprog tasks in general. Just because you CAN type 100+ wpm doesn't mean its a good idea during a screencast. The content is very compelling, regardless of editing decisions.
Something I don't like about retrocomputing is stuff I started out doing is now considered retro. Or even worse, stuff that was futuristic when I had a couple years in, is also considered retro. I guess getting old beats the alternative.
