BoostUpStation - Had an issue on a phone that I thought I had bricked, and this was the only place that I found a fix for it. Not XDA, no other sources had a fix for what I fucked up. I've been unlocking and flashing ROMs on phones since the Cynogenmod days, and this guy knew his shit, has a lot of other really informative videos.

ExplainingComputers - Focus mostly on SBCs but also does many other good videos. His recent video on Windows 11 was spot on in my opinion.

ExplainingTheFuture - Second channel from above, here he does a little more longform content on interesting topics.

digiblurDIY - If you care about having IoT devices locally controlled, this is your channel. This guy is extremely knowledgable, shows you how to flash Tasmota or ESPHome or even swap chips on devices to make them local.

Learn Linux TV - Has some interesting videos if you are into selfhosting and Linux.

Brian Lough - Videos on making things with small boards like Arduino boards.

DIY Solar Power with Will Prowse - Not sure if this would be considered tech or not, but this is a really good channel if interested in solar power and battery banks.

Hak5 - Security news

LGR - Cool retro gaming videos, I'm guessing most people already know about this one.

Louis Rossmann - He does a lot of talks on issues around tech, the big one is right to repair. His recent video on fixing a vibrating ring was quite funny.

Modern Vintage Gamer - Retro gaming, goes into a lot of the history of the modding scenes too.

Morgans Mods - For those intersted in home automation.

NostalgiaWindows - 90s kids will appreciate this.

2GuysTek - Found this in the Linux fallout, seems to have a decent, grounded take on it so I've recently subscribed but do not know much about the channel.
