This is the first channel that comes to my mind when I think of YouTube. UK based, features a strapping young lad with a particular sense of humour. He covers gaming as the channel's name implies but he does it from the perspective of computer hardware and its capabilities. He covers a lot of computer hardware (old and new) and pre-built systems. Great channel for the budget-conscious viewer.
James Rolfe and his Angry Video Game Nerd series. Must watch, highly recommended, specially the early seasons. Also there are a couple of movie analysis episodes.
[YouTube] Protect this man at all costs. Phil specializes in retro PC hardware, software and systems in general but also tends to focus in sound cards and audio solutions more than anything. He's a very meticulous person, you can notice he goes into every option and tries every combination about a topic before publishing a video. He has a very resourceful companion website to support his channel in which you can find a compilation of drivers for old hardware and much more: https://www.philscomputerlab.com
[YouTube] Hosted by Christopher Barnatt, this channel has a vintage feeling but actually covers newly released stuff. This channel covers in depth, as its name suggests, computers (hardware and software) but has a heavy focus in single board computers, the channel is well known for that. Chris also has a very 90s looking companion website to match his releases on YouTube plus many, many more key information. The SBC page on his website has been for me a very helpful SBC hub, it could help you too find the right SBC for your needs. Have a look at his profile and you'll see he is quiet a figure: https://www.explainingcomputers.com
[YouTube] A strongly recommended channel for the US folks. This channels covers the ongoing PC hardware deals, mainly Amazon and Newegg. The main host, "the tech dealer" is scarily what I consider the most overall intelligent mind in the world. He has figured out everything about everything: You give him the variables, he process them and always comes out with the right conclusion. Man, I wish this guy to be my priest when I get married hehe. Anyways, this channel is a family owned one and you can feel it after you have watched it a lot. What I like very much is when in rare occasions, he pulls out his hat and becomes "the PAPA deals" and starts lecturing you about economics and life in general...truly a wise guide to follow. Man, I wish this guy to adopt me. A solid recommendation to follow, he explains video after video, in full details, the same topics over and over again and he never seems to get tired of helping you.
[YouTube] I don't know anything about the person behind this channel but he seems to be a complete champion in his area. Somehow he covers the exact same programming topics I'm into. I seek guidance and "confirmation" in his videos. Totally recommended if you are into C/C++ and/or computer gaming programming.
[YouTube] Prepare to melt your brains. This guy, he's one of those. What an intelligent mind, be afraid. I'd personally put him to lead a country instead of a YouTube channel. He covers deep programming topics beyond your understanding but he does it in the best way possible for you to get it. You'll definitely need a background in programming for this one. Extremely recommended for programmers in general and specially for game developers.
[Page] Fascinating article about a subjective opinion of AES-GCM, its design, pros and flaws. Conclusion: Unless you have guaranteed access to hardware AES instructions then use XChaCha20-Poly1305.
[YouTube] Hosted by Johnny Millenium. He showcases his video game collections and gaming experiences in a very personal, warm, nostalgic and happy manner. He goes a couple of times beyond games and covers illustration, comics, manga, anime, books, music, other collectables and hobbies. Also with supporting footage. Apparently he has owned every game console or system able to play video games. A complete family man now, he never seems to run out of topics for his videos.
[YouTube] Hosted by Jason, this channel goes heavy on game collecting. It is known for its guests format, having friends and savvy people (sometimes from other channels) co-hosting the show. This channel covers all the gaming platforms and their game releases. Pay attention to the "hidden gems" series, you may found your next purchase in there. It is colloquially said that when that series goes live, all the games covered there spike in price. Many blame the show for the market price hikes but there is no solid way to link that to the channel. Oh and shout-out to "Radical Reggie" (The Radical One), he's a frequent guest in the channel and he's a serious lover and collector for the Sony PlayStation consoles and also apparently the Nintendo GameBoy Advance.
[YouTube] A gaming channel for the technical ones. This channel is right now entirely run by Joe Redifer, his partner Dave took a different path in life but does some cameos from time to time. Joe is a very technical and meticulous person with all his stuff, he's well known for that. He goes into deep details when covering hardware and game releases. He's also one of those persons that go into every option, check ever combination possible, try new things and find workarounds. If you need something to be found in a game, Joe is the guy. The channel is well worth for the stop motions, the best ones you'll ever see. Joe is a professional stop motioner more than anything. Oh and don't skip the endings, Joe always has an extra sketch for you in every single video. Great work Joe!
[YouTube] Another channel for the technical people out there. MVG is unique in the sense that it tackles hardware and software topics not only from a technical perspective but also from a hacker/programmer one. The man himself being a clever game developer pro, he was involved in the early scenes of the original X-box homebrew. Here you'll watch videos about hardware and software but generally about some flaw, something that was well done, or something that impacted the gaming community. Very well known channel for its "Mistakes were made" series.
[YouTube] Carl is not Carl. This channel is absolutely recognized for its dedication to Super Mario Maker. Troll levels, puzzles and all sort of creations are all extremely fun when played by Carl. There is a lot of channel culture to be acquired in order to understand all the memes. There's almost not a single time when Carl is not laughing, screaming or talking about science. Seriously, his laughter (and gameplay) will cheer you up and bring you joy whenever you need it the most. A good and positive recommendation overall.
[YouTube] Vinesauce as a whole is the biggest brain fart on the Internet, you'll love it. It is mainly Vinny and then Joel doing videos separately on their own. I personally watch Vinny the most, sorry Joel. Vinesauce is generally gameplay with brain farts in the background but then there is also...it's impossible to explain here. Watching this channel is more like an important life choice or life project, you'll have to invest a lot of time into it to get what I'm saying. I suggest you to start watching the Metal Gear Solid series (1-2-3, forget about the date) and then you could jump into the more modern stuff. On a personal level I like Vinny Vinesauce because he is a very clever guy, he does a lot of stuff, he is well connected to ground but can also move to higher levels in life/thoughts/philosophy and have empathy. The thing I like the most about him is that he has something that I don't and that is the ability to fully express what's on his mind. He can dump whatever is on his brain to full extent and still be understood, I can't do that and I treat it like an ability or a gift. Recently, Vinny made a poll about what is the most liked thing on the channel: Most people voted "Gray Leno" but it seems I was the only one that voted for "the fart with reverb", buy hey that is just me. I like to play this channel while I do other stuff because I feel like I'm hanging out with good company. Vinny, you are like the brother/best friend I never had but always wished, sniff. I'm not crying, you are.
[YouTube] Mitch is/was the world record Super Mario Bros 3 speedrunner. His main community comes from Twitch but then YouTube gets the edited playback versions and recently simultaneous livestreams. Mitch focuses in SMB3 speedruns mainly but also is a NES adept and occasionally plays other Mario games, also from other consoles and all from original hardware. Aside from the game runs, it is all about the community bashing Mitch and then Mitch bashing back the community (in a fun and jokes context). I personally and heavily recommend the "SMB3 points-based tournament" (all seasons)...OMG what a great series.
[YouTube] Small but good gameplay channel that covers mainly classics and their remakes. I am personally fond for the PlayStation 1 games in there (a lot of Crash Bandicoot). For some time I thought the person behind the channel was an A.I. because the level of gameplay is immaculate, you would think it is a TAS playing and not a human. This is a great channel to be used as a guide, I've used it to help me with Crash Bandicoot 3, Cool Boarders 3 and Serious Sam HD TFE. It is always nice to playback this channel and relive the good times.
[YouTube] John Bain, the Cynical Brit, the TotalHalibut. Sadly he is no longer with us, at least not in physical form. TotalBiscuit was a video games critic and commentator that lived through the best gaming times and provided us with entertainment, honest opinions, meticulous reviews, recommendations and a strong British accent. It is all still there for you to watch. He caught my attention because he was almost the only one that before starting a game, he reviewed the entire main menu, exploring every option and even gave his veredict on the looks and usability of the GUI. The channel was well known for its "WTS is..." series. I'd suggest that you watch one video in particular: "WTF Is... - Warhammer 40k : Space Marine ?" as a small introduction and then I'd also suggest you to watch his Terraria sessions with Jesse Cox. We miss you John, R.I.P.
[YouTube] A great tinkering channel with modern (and old) technologies put to use. Mainly an electronics projects channel: You will find a lot of science here, a lot of experimentation and some weird creations. Scott is very methodical, well organized and does explain the math or shows the diagrams for his projects. You'll have to dive into this channel because there is a lot to uncover.
[YouTube] Luke's channel feels like an original youtuber one. He does a lot of electronics repairs, specially arcades and video game consoles. He also has "some of that" (channel's culture) retro gameplay on original hardware and software. Some collections from time to time. He is living in Japan which affects the hardware and the games shown in his videos. There is a little bit on Japan culture. I personally recommend all his "Hard Off" videos, they are relaxing and addicting. Actually watch all of his videos (the date matters not), they are all entertaining and informative.
[Website] Renzo Mischianti's personal website. This website contains many articles to SBC and microcontroller stuff. Particularly for me, his ESP32 articles were very helpful and maybe they can be for you, have a look. There are many embedded computing websites but this one I liked the most. A little gem on the Internet.
[Page] A useful tool for the ones that don't have all this knowledge on their heads. You build the resistor value by choosing the resistor's color bands.
[Page] It is commonly acknowledged that fans should not be regulated with resistors. There are better ways like a variable stepdown. We use resistors because they are cheaper and have a small footprint. If you insist in this route then here is an informative page with a resistor value calculator.
[YouTube] A very special music channel. This guy mixes multi-channel, video games themed, Acapellas all by himself (and Charl, his cat). Amazing compositions that you'd definitely want to check out. There are songs for the most well known game titles but even if you don't recognize them, it is quiet fascinating listening to them. A lot of time and quality has been put into his content, please give it a try, you'll absolutely love it.
