content: Even leaving aside the obvious fakes and scams I find most videos quite useless. I search for "how to make X" and I get a bunch of videos where some guy is seen working with his tools for 30 or 40 minutes and, at the end, he has made something.If it is wood he is seen using the table saw, the drill, some hardware... and in the end he made some piece of furniture or something.If it is metal then he is seen using a lathe, a drill press, maybe a milling machine and in the end he made something.If it is basic electronics he is seen soldering a few things together and in the end he has made something useless.I just don't get it.I know how to use tools. If I didn't know how to use tools I would be searching for videos on how to use those tools.If i want to build a structure, a piece of furniture, a metal thing,a tool, an electronic circuit then what I am looking for is plans, ideas, designs, drawings, diagrams, schematics. A tutorial on everything I need to know, what I should look out for. That is what I need. Not just watch some random dude in his workshop doing things. That contributes nothing to what I am looking for.I have to wonder if those videos are directed at people who know nothing on the subject and just like watching other people work.I want a good intro an what you are going to build. What is the finished product. Then a good explanation on how to go about it. I do not want to see a video where the guy just starts out cutting lumber in a mysterious fashion.Just give me a set of plans and don't waste my time.And get off my lawn! Sheesh!

content: Quote from: soldar on March 18, 2024, 09:46:56 amI, too, don't think howto/tutorial videos are sufficient for conveying such information.I once got into an argument with Dave about how useful tutorial videos are. Dave ended up calling me a troll. :'( I don't think I was expressing my position clearly at all.I know there are people who prefer videos, and obtain sufficient information from them, but I always worry that they only get a superficial understanding, only enough to look like they understand; that they do not understand enough to correctly apply the understanding in real world situations.The best videos are the ones that describe the reasons behind the choices in the plans or implementation. Stuff like "this gusset is here to support the join in case of forces in this direction, and that cross member spreads the load between these points", or "to transfer these signals over 1m distance, we're using twisted-pair cable with a shield foil/mesh and differential signaling" or "the primary winding is triple-insulated, which helps avoid shorting mains to the low-voltage side; this is good for safety".I particularly like the teardown videos by AvE (BOLTR), BigClive, and DiodesGoneWild. It is never just "this is good, buy this" or "this is bad, don't buy this", but an examination of what in the thing is done well, and what is iffy or downright dangerous. You need practical experience to do that, and the videos are like looking over the shoulder of a talkative old hand who is telling what they see and think. It is not that their opinions matter much, it is more that they describe the reasons, experience, and logic behind those opinions; and those are the valuable part that is difficult to obtain except through lots of practical experience.Funnily enough, I often encounter the exact opposite in higher math, where the disposition centers on proving some statement or other is formally correct, but applying it for solving real-world problems is usually left "as an exercise": exactly the opposite to what is most useful to me and people like me! Seeing Bessel functions still makes me cranky.Thus, I do admit that there are people who get everything they need out of tutorial videos and similar material, but I don't; and I worry that of those who claim they do, most get an understanding that is too superficial/simplified to actually apply in practice.

content: Quote from: soldar on March 18, 2024, 09:46:56 amPretty much the whole idea with Youtube. Entertainment and views.As soon as you concentrate on design, engineering, or any profession really, you narrow down the potential viewer base and don't earn any money (there are of course a few exceptions). I see this in many areas. Many have tried taking their profession to Youtube and tried to make a respectful amount of educational videos. They get a few hundred views, so they don't earn any money. Then they start doing these stupid Reaction Videos, in where they sit and stare on a video clip of someone else doing something and possibly giving their expert opinion about it. Suddenly they have tens of thousands of views. It's ridiculous.Look for a reference to a blog, web page or github with design plans. Or their videos are 30 to 60 minutes and consists of several parts. These ones are serious, but few and far between.

There has to be ademonstrable reason explained in advancefor me to watch them.

Rarely, how-to YT videos have links to sites with "16000 woodworking plans" or such more stuff. These sites are not free.If you demand useful and practical information -- pay for it.

content: I disagree with the OP. In today's world where manufacturers who make any type of electronic aren't releasing resources to help repair their products, YouTube can be a more powerful tool than ever to help the customer repair the product themselves.Some YT creators are better than others at conveying information. Some have become professionals at it like Dave Jones and others might just be putting up one video that they think could help someone else. Have you ever watched w2aew's channel? He provides tons of how-to videos on different EE topics (novice to advance) and he is an excellent teacher. Probably one of the best IMO. And there are many others out there like him - you just need to find them.I started my own channel last year. It is more of a videoblog to document my experience learning electronics. It has helped me continue to learn because people with more experience will comment and provide me more information on the circuit I might be working on than I knew before. At the same time, I get people commenting from all over the world asking for help repairing their own products. It's pretty cool! I'm also a Lab Instrumentation Engineer working on lab equipment where the manufacturers of said equipment are nortorius for keeping all info on how to fix thier products propriety. So I'll put a video up on fixing one of these pieces of equipment to help someone else in my position who has no resources.I do agree with some of what others have said in that everyone has different motives for putting up their videos. And people have different reasons for watching them. But regardless, they are far from useless.

content: Quote from: fmashockie on March 18, 2024, 01:39:16 pmWell, you would disagree, wouldn't you?Let me expand my OP. There are channels that are entertainment, comedy, etc and they are fine for those who are entertained by them. There are even channels, like This Old Tony, where comedy is an important part of the show.There are channels that deal primarily with tools and how to use them, metalworking tools, woodworking tools, electronic etc. Fine as long as they are done competently. Stumpy Nubs comes to mind.But I am referring very specifically for videos I get when I search for "How to do X" or "how to build X". Clearly I want to build X and what I want is a video where the guy first of all shows the finished product and explains the basics, the advantages and the limitations, the pros and the cons, the materials and tools needed, etc.I do not want to get started on a video where I am going to watch a guy working in his shop for 35 minutes, not even knowing what he is building, and have to wait to the end to see if it suits my needs. Nope. Sorry. Not watching.Also not interested in clickbaitty nebulous titles like "why don't welders do this?".Also, as has been said, guys who are wasting time with ums and hums while the figure things out, like I am their friend there just keeping them company. Nope. Sorry. Don't waste my time.Matthias Wandel is pretty good in that he starts out explaining the issue he is going to solve and how he is going to solve it. He does not waste time. Cutting, drilling and other routine operations are speeded up. Good because I've seen a table saw cutting wood a million times already and I have no interest in seeing it again. He explains the how to do it and that is enough. His audio could be better but I guess it can be overlooked.This rant was triggered because I thought of making a sheet metal brake, to bend sheet metal and make enclosure boxes for electronics. Most of the videos suggested by YouTube were absolute crap. If I do go ahead to build a sheet metal brake I will probably start by making my own design. YouTube is not helpful.

Some will link their plans if they've bothered to create them, but often its just some one off build based on what parts they had on hand.Terrible rant.

content: I have learned an enormous amount from YouTube, across a wide variety of subjects including electronics. It's why I've paid for a Premium membership for many years now. Sure, the signal to noise ratio can be a problem, but when I find a good channel I subscribe to it and check it regularly and don't waste a lot of time on useless videos unless I'm only looking for entertainment.Put it this way: my YouTube to TV ratio is probably somewhere around 1000:1. And I have multiple 4K TVs all over the house with Apple TVs and a subscription to almost every streaming service you can name (certainly the big ones). The family benefits more from that than I do.

content: Yea, it's hard to sort the junk from the gems. Some tasks do lend themselves to video format quite well, like how to do some specific mechanical task such as bleeding the brake system on a car.But as for building an electronics project, video really sucks when all we need is a schematic, mech drawings, parts list, etc. Video usually adds very little value.I find myself watching many YouTube instructional videos at 1.5x or even 2x speed just because the creator talks too slow or takes forever to get to the point.

With just a few seconds you could have a look at the intro and the illustrations and know if it was something which might interest you. You could skip forward or back, you could stop to review something specific.No doubt though that video has an advantage when needing to illustrate movements or certain techniques.I am referring only to videos about how to build this or that. I am not referring to humor or comedy or interviews or arts, etc. I am referring to things like "how to build your own diesel-electric submarine" and all you see is a guy welding for a long time.

There are very few technical videos where moving pictures are vital; I mentioned the Pace soldering videos as being one of the few examples where movement and pictures are important.

YouTube, like forum sites, get content from outside creators and manage to (hopefully) make some profit after paying expenses.For regular website pages there used to exist places like Geocities but they have pretty much disappeared. Surely it must be much cheaper to host a few pages with text and pictures than to host and serve video.I used to have my pages in Geocities. Then I moved to hosting I had to pay and when the price skyrocketed I just took them down . I do not understand why I cannot find free or very low cost hosting.

content: I come down in the middle. A blanket condemnation of YouTube videos seems inappropriate. But I do agree that it is often a frustrating medium. A great many of the presenters enjoy the sounds of their own voice too much, spend too much time setting the stage for what they are doing or whatever. My boredom threshold is exceeded long before I even really understand where they are going. And there is plenty of scam material and material from people who should really learn to tie their shoes before trying to teach someone else how to do something.After saying all of that, I really do learn a lot from the videos. Sometimes a better way to use my tools. Sometimes a tool I didn't know I needed. How to reach the damned connector for an automotive sensor that is buried between the firewall and the engine. And many similar things. While tggzzz is right, reading is a lot faster, I can absorb the YouTube material while sweeping the floor or doing other mentally non-challenging tasks that would be difficult while perusing a paper document. And that presumes that an appropriate paper document exists. It is hard to write a good document on how to get to that buried automotive sensor, but there seem to be a lot of both professional and back yard mechanics that can put up a video that is useful for this type of thing.YouTubes algorithm for suggesting videos isn't too bad. It has learned that I really am not interested in the flat earth material, the gotcha political stories, and all the other drivel that populates the channel. At least 10-20% of what it suggests that I view I actually find useful or entertaining. And that is a rich enough vein for me to continue processing the ore.

content: This is a rant repeated to oblivion and the generalization carries zero merit. It is similar to say that Google is useless because it returns 110.000 hits on a subject and most of them are off-topic. You can get better at handling the search tool and its switches/syntax. Also, the more you use it, the more you develop a feel for the type and quality of content based on the title and the channel/website.I have used the platform to create "how-to" videos for GUIs that carry much higher information value amd lead to a much faster resolution when compared to a wall of text. Explaining menu options, right-clicks and other events (which ironically are sometimes shown in an animated GIF no less) are less efficient in text. Concomittantly, I also created long form user's guides and quick tips in text form, only to notice how short span attention is prevalent these days. A large number of people complain there is no user's guide, then when pointed out to it, don't read and ask questions where answers are easily searchable in the documentation.At last, as tzaboo mentioned, the financials are extremely favourable to publish content on Youtube, Odysee, etc.

content: Quote from: CatalinaWOW on March 18, 2024, 11:34:57 pm"Tips and tricks" type of videos, as well as tutorials on how to effectively and safely use a tool, are indeed useful. (Clickspring, Joe Pie, Blondihacks, Keith Appleton, et cetera.)There are also quite a few two-minute or shorter videos on how to open various laptops and tablets without damaging anything, and those are excellent, better than a text-with-pictures. In fact, the ones I like don't even need any audio, as the visual steps suffice.Dave's jellybean component videos (or rather, their audio!) are similarly useful. Something you might learn from a more experienced coworker or adviser at a sequence of coffee breaks or one-on-one brainstorming sessions. Very useful.So yes, there definitely are things best described using a video/audio; no question about that.As I understood the topic of this thread, and how I answered, was on the statistical side: the proliferation of using videos to present advice in cases where a video is a poor format for it.The worst negative examples I can think of are math tutorials. Presenting the needed steps with short sentences explaining what is done at each step and why allows each learner to proceed at their own pace, and concentrate on the detail they have most trouble with.When I was at the university, I often annoyed other students by asking the lecturer why a specific solution approach was chosen. Annoyingly often the answer was a variation of "because it works", which meant that the lecture itself was useless to people like myself who assume that the mathematical proof of the method stands, and are only interested in applying the method to solve "real-world" problems. For example, I still have not found any description for choosing a solution method for partial differential equations other than "try each until one works". Iknowsuch a method works, because ask any mathematician, and they'll show you the working method in real time; I just haven't found one who can explain what they based their choice on (except "I've seen this form before"). Even Arfken-Weber-Harris ("Mathematical Methods for Physicists") scatters the solution methods all over, as if they were completely different things –– and of course, to a mathematician the methods are different, with the only connection being that they can be applied to the same general type of problem.The mathematicians I've complained about this just give me the side eye, O.o, o.O,They don't seem to understand at all what I'm complaining about.Similarly, like I mentioned in my earlier post, I do believe some people get all they want from videos. I do not, and I do not trust that all who get what they want from videos alone, actually get an understanding sufficient to apply in the real world successfully.I do get more than a bit frustrated when those people assert that because they believe they themselves do get sufficient understanding from videos,everyone must also, and that anyone complaining otherwise is just stuck in the old times and complaining out of contrariness.

content: Quote from: Nominal Animal on March 19, 2024, 08:09:16 amAgreed and agreed, because "short" and "moving" and "text superfluous".QuoteAgreed. But don't forget the large books in the library containing mathematical functions/operations. Using them is a case of visual scanning and pattern matching until something suitable is found. Mathematicians were (are?) addicted to them.Also don't forget something as basic as integer division is a process of successive iteration. Subtract repeatedly until you've gone too far, and then reverse, and repeat with the remainder. That isveryobvious when you see how mechanical calculators operate. You have to crank the lever several times in one direction until a bell rings, then reverse one crank, shift left and repeat.PDEs and to a lesser extent integration is also similar trial and error.QuoteThat is, IMNSHO, a classic indicator of Dunning-Kruger syndrome. While it may be sufficient for monkey-see-monkey-do tasks, it will be insufficient for many novel innovative tasks.

content: Quote from: tggzzz on March 19, 2024, 09:30:03 amTo be clear, I was not actually referring to anyone participating in this thread, any past thread here, or any personal messages sent to me!I was remembering the few cases where I was tutoring or trying to help a teen, and reached for a book or suggested a chapter in a book, and they responded with something along the lines of "can't you find a video for me instead?" followed by a frustrating discussion about what is understanding, what is knowledge and application of understanding, and what is copying and learning by rote.I only realized just now that that part could be read as if I was railing against anyone asking if I knew a good video on some subject; that's not the case at all. For example, RoGeorge recently asked me for advice on a good Python GUI tutorial book/article/blog/video in the Programming / Python thread, but I couldn't give any because I haven't seen any. (I ended up posting an example instead.) There is absolutely nothing wrong in considering multiple different sources, and even falling back to Youtube when nothing better can be found!When tutoring teens in math and physics, the hardest part is getting them over the "I don't know how to do this!" / "I can't do this!" mindset.(There is no "can" or "cannot", there is only "try and see what happens". Force and Magic can smell my butt. Take it one step at a time, no matter how unsurmountable the problem might looknow.)I believe this mindset is related to the quick and easy answers that proliferate on the internet, with actual understanding requiring effort that is not normally rewarded or required, leading to the superficiality and short-term objectives; with videos preferred over written text simply because they require minimal (cognitive) effort to pass the minimum requirements.The meme version of my complaint is "I don't wanna read that, it's too long. Can't you make it a TikTok video instead?"

You could probably train a machine to recognize which solution method to apply given a sufficiently large training set of PDEs. With experience, a human brain could apply the same learning. We tend to call this "intuition", but in reality there is no such thing. Intuition is just a fancy word for "I can guess what to do because I see a pattern in the data."

content: I want to double down on one of my prior points. A good textual document is more than enough for almost all of the topics mentioned in this thread. Such a text is difficult to generate for most people, and the number who can do it well is in my opinion declining in this video focussed era. Meanwhile the number who can do an adequate or better job of video content creation is increasing.This partially changes the discussion from suitability to availability. Trash text content has always existed. Time winnows out the lesser documents. Presumably the same will happen for video.

Most of what I want from those videos is to see how things fit together. For most things its complex. If learning from books was so great, why would people spend a fortune to learn from lectures in colleges? Really smart people learn quickly from book, while less able people gain massively from lectures. However, even the smartest people pick up new things faster with a combination of books and lectures.

For understanding ideas, graphics are generally the best choice, but for seeing around the details of a specific product, and how awkwardly shaped things fit together, video can be a real boon. A key issue with the proliferation of how to videos for niche things, like specific product repair, is they just wouldn't exist if they were not as quick and easy to produce as a crude YouTube video. So, your choice is a less than ideal format, or nothing.

I like my intuition, but I'm pretty suspicious of its correctness, too.I call the understanding of the properties and behaviour without understanding the internal details "intuitive understanding", mostly for a lack of a better term, and because to me it is similar to being able to catch a thrown ball without being able to describe the trajectory of the ball (except in the crudest of approximations).

content: Just going to throw my 2 cents in:There is certainly a lot of junk on youtube. But I have found it to be an amazing resource even more. When I need to repair something in my home there is often an easily found video explaining and showing exactly how to do it. And often I'm looking for a repair for a specific appliance or auto part and I can find a video showing how to do the repair not just on a generic dishwasher or car, but my exact model.Most of the time it's not too difficult to avoid the junk or quickly ignore it since it's usually clear within a few moments that it won't be much use.On the negative side, there are many tutorials that would bemuchbetter in written form than in a video. But who am I to tell someone how they should offer/present something I'm not paying them for? I'm not their boss.It still amazes me how I can go to my computer or phone and ask nearly any question and much more often than not get useful answers immediately.It's like I'm living in Star Trek!

content: Quote from: Mechatrommer on March 21, 2024, 11:40:05 amMan, you sound like you are a bit cranky today. Is everything OK?Nobody is questioning the "right" of anyone to upload anything. I do not question "the right" of people to be rude, or have bad manners, or not use proper hygiene, or dress inappropriately or use bad grammar or bad punctuation or bad capitalization and spelling. I recognize the right of the people to do those things while, at the same time, I wish they didn't do them.And it is my right to express my wish that people be a bit more civilized and a bit less stupid. And I wish there were fewer videos but of better quality. That's all. I am not proposing we outlaw stupidity, bad quality or bad manners.It is my contention that videos which purport they are going to teach you how to build (say) a piece of furniture and then all you see is some guy working in his workshop, those videos are a waste of time and telling me to skip them is stupid because I have to open them and watch enough of it to realize it is a waste of time.

Even though I taught classes for years and have given hundreds of in-person presentations, I don't ever try to "wing it" when I record videos.My usual method is to record the whole thing straight through, backing up a sentence or two every time I make a mistake (and I make lots of mistakes). I then go back and cut out the "bad parts". No fancy editing skills necessary - just select the parts that I messed up and hit "delete"

content: Quote from: Mechatrommer on March 21, 2024, 01:17:38 pmAnd that is at the root of the entire problem. Instead of constructing your argument logically, you spew something out, and expect readers/listeners/watchersto know what you meant, instead of read/hear/see what you said. This is wrong.Quote from: Mechatrommer on March 21, 2024, 01:17:38 pmNo. I can read and integrate what I read quite fast, and I habitually watch Youtube at 1.25× or 1.5× speed, depending on how clear the accent is.When you use the poor search engine Youtube implements nowadays –– it isn't precise at all, and prefers its own algorithms over exact word matches ––, after winnowing the search terms down, you typically get about a dozen results. If only one of these is useful –– and that is commonly the case, except when the same video has been reuploaded by many people in the hopes of monetizing others' work ––, statistically you end up watching the beginning or spots of at least half of the videos. This takes dozens of seconds per video.I can read and understand and integrate the abstract of a peer-reviewed article in less than a minute, and estimate the usefulness of a "how-to" page or blog within seconds; let's say less than ten seconds per page."Difficult" here means "it takes more time than it needs to, and is thus wasteful and inefficient". Because I cannot implement my own Youtube search engine (their TOS forbids such, even if it were technically possible, which it isn't), I cannot affect the search situation at all. The increased amounts of garbage videos means the density of useful videos to garbage videos is steadily decreasing, and thus finding useful videos will require more and more effort, for a shrinking yield.You know this is happening to yourself too, because when you look at Youtube search results, you will look at the author and view count of each suggested video, simply because most videos are not worth watching, even though Youtube claims they match your search results.The solution to this problem is telling humans and authors how to do better. It is not being "the boss of them", it is the internet-age equivalent of not littering.

There was a "YouTube" back then, but it took a different form, and that form was magazines (not textbooks). Newsagent shelves were full of monthly magazines all all conceivable subjects, with several titles covering electronics. Every child who wanted to learn would be buying these magazines.The magazines would contain projects, reviews, tutorials, industry news, and adverts for all sorts of things to buy to make stuff.Granted, magazines have not quite gone away, but it is hard to imagine how rich the scene was in previous decades.One thing to mention about the difference between magazines and YouTube videos, is that magazines have editors to curate the content and maintain quality standards

They also aren't well-organized into categories and only a few of them have a cover that lists what's on the inside.Oh, and they are all freeI spend a good amount of my work day creating content that appears (among other places) on YouTube, so I'm all too aware of the challenges of finding concise, clear, and accurate technical information. No idea how to solve that problem - sorryIncidentally, one of the things I love about Germany is how many magazines are still being published compared to the United States. I'm amazed that even the smallest Buchhandlung sometimes has half a dozen magazines on a single hobby (model trains, chess, horses, etc.)

content: Quote from: pdenisowski on March 21, 2024, 01:53:00 pmI suppose with a little practice you can edit quite fast. It would take me forever. Steve Lehto must do the same thing but alsoyou hardly notice the cuts because the video is transitioned over a few frames and he is sitting still facing the camera so it is just a bit of blurring. And you cannot notice anything in the audio stream. I suppose with a bit of practice and the right software you can move forward quickly.It is not only the content that is important but also the quality of the video and audio.There is a guy who has a channel in Spanish and he does videos which are just unbelievable. He will record a 20 or 30 or 40 minute video outdoors, by the beach, in the wind, in one single take, with perfect audio and video. He is moving, walking, sitting, turning and delivers a long monologue without a hitch. I assume he had a very good cameraman but I have no idea if he can memorize the entire thing and if he just keeps doing it until he gets the entire thing right. In the technical aspect that channel is just amazing. I suppose professional actors also need to memorize their lines but I find it amazing. The guy can talk about a movie, a book, a character from Greek mythology and you know he is not improvising because the entire speech is just perfect. I guess that is what a true pro can do but I find it amazing when broadcast TV, where they have more means, is much lower quality. This guy is someone doing it for the LOLs and who says he does not want monetary support. Once in a while he will say something like "As you know I do not ask for monetary support; if you like what I do and would like to do something then get on the phone and call your mother or someone you know is lonely and tell them you love them and you care". I find his videos not only interesting in their subject matter but also impressive in their technical quality. Some things which may seem like defects are actually designed that way and you can see he repeats them in many videos. Every tiny detail is planned and designed that way. A perfect product done just for the pleasure of doing it. A very rare thing these days. As I say, the channel is in Spanish (even though the guy ran away and lives in Cyprus) but if anybody is curious, you can see his videos iXc5PYH04F0 , 7HyaiL5nwlo , gK_Cll61G-c , _mDsPCkNP-A , They are quite representative of some of his work.

I'm serious, and not trying to be snarky or anything.We're not talking about work log videos. I watch Cutting Edge Engineering Australia every Friday, Bad Obsession Motorsport whenever they get off their arses to publish a video, Frank Howarth's and Keith Rucker's work log videos, yes. Nobody is complaining about those, because those videos are about what they do for fun or profit or both.We're also not talking about videos that show how to replace the battery on a specific model tablet without breaking it, or how to reach a particularly tricky doodad on some model of cars. Those are fine, too, because they show a procedure that should not cause any damage while doing it.We're talking about the crappy videos that are supposed to help others but really do not, because the person does not understand what they're doing.For example, consider a video where someone is showing how you can tell a battery is almost depleted by simply measuring the cell voltage with a voltmeter.That is bullshit, because you need to load the battery (with a series resistor) to see what kind of a voltage it hasunder loadto tell how depleted it is.

In every project he would start out by showing the finished product; what he was going to build. Whether it be a greenhouse, a shaker chair, an amish cupboard, whatever, he would show it, describe it, point out what made it special, things to pay attention to.HE would then make the parts but explaining very precisely why he was doing it that way, why that joint needed to go that way, why this part needed to be glued before that other part, etc. It was not just him working with the machines and without explanation.Those programs were very well scripted and were very useful if you ever wanted to build those projects but even if you were just watching you would learn useful techniques.Watching a guy cutting lumber on the table saw without explanation is a waste of time that gets you nowhere.

Statistically, what do you think are the odds of a given video meeting your expectations? Practically zero. And that's normal. If you find some channels with great content that meets your expectations, great, enjoy. Otherwise? What point is there to make? It's just a completely "open" platform at zero direct cost (if one has a problem with the indirect costs, frankly the best would be to just go elsewhere), so complaining is exactly like, say, listening to hundreds of people in a meeting on some topic and coming back with "wow, those guys really suck!"

content: This thread is very reminiscent of an Eti thread.I don't like x. I expect x to do this. but x doesn't do this, and people should make x do this for me.Viewing youtube videos is optional. And if you are complaining that many - perhaps most - are "useless"to youthen I'm not sure what you expect anyone to do about it - or care.I suppose if your job is repairing things, and the first way you approach that problem is to look for youtube videos, then I can understand frustration if said youtube videos explicitly state they show you how to do said repair but then fail to do so. But I suspect that isn't what you're on about. Sounds like you assume and expect something from a youtube video from its titel, and it doesn't live up to that.There are myriad reasons people upload videos - money, likes, a genuine wish to help others, because their friends are doing it. Also - they are free for you to watch and as such come with no guarantees or quality control (whatever you expect that to be). Not sure you can compare youtube to old books, newsletters or even pre-2000 websites, as all of those had a higher bar because it cost money to publish and present that information, as such, it was more to the point, and generally more reliable.Maybe take a break from watching youtube for a while and spend your valuable time doing things that dont' make you angry?

Just like everything on the internet, since the bar for posting content/opinions/views/reviews is so low, its diluted so the price we pay for the convenience of having access to vast amounts offreeinformation is that one has to sift through a lot of crap. Nothing wrong with watching youtube videos, but it seems the OP was complaining that they spent lots of their time wathcing them - then complaining that they weren't what he wanted. Surely the simple answer is.. don't watch them?

content: Quote from: Buriedcode on March 22, 2024, 07:55:44 pmI think this is not true, but the good information may need some searching.You can tell if a review is worthwhile by watching it, but this takes some discernment. It is not that hard to see if someone properly understands the product and is evaluating it critically, and is not just describing it.

content: Quote from: IanB on March 22, 2024, 09:32:12 pmI have sufficient discernment to evaluate 10 sources.I don't have time to evaluate 10 videos, but text takes much less time to evaluate.Hence I don't watch random videos, only those recommended by other people with sufficient discernment.

content: Quote from: IanB on March 22, 2024, 09:32:12 pmIn the days before internet when you considered doing or purchasing something you either looked in a printed resource or went to a local expert. The printed resources were (depending on your location) hard to access in both time and money, but quick to evaluate. For this reason meta evaluations were common. That is you developed trusted sources and didn't often chase other sources.Local experts basically were either people who sold the service or product your were interested in, or someone who owned or had done what you were investigating. When buying a product these sources sometimes gave you nothing worthwhile. The most common and slightly better situation was to be able to see all that came in the packaging, and maybe to handle and operate the product. Less frequently, but not uncommon you could find people who owned or used the product and could tell you if they were happy, perhaps throwing in a couple specific raves or gripes. And rarely you got someone truly expert with the product who could succinctly identify all the strengths and weaknesses of the product and offer comparisons with other similar products, perhaps including a recommendation based on expected usage.YouTube (and the internet in general) provides analogues for all of these situations. The descriptive YouTube unboxing video is very much like seeing the floor display at a store staffed by clerks who know nothing about the product (except perhaps which one is being flogged by the sales manager). The strategies for dealing with the problems are also very similar. You don't return to retail stores that aren't helpful, and the same for YouTube channels.For those of us not living in a megalopolis with free access to a major university library and a huge variety of retail outlets the advantages of the internet versions easily outweigh the disadvantages which are mostly low entry barriers resulting in lots of low quality content and the data which is the most ephemeral in human history. Those with better access to the traditional sources may easily find the opposite to be true. Unfortunately the loss of the hinterlands market has drastically hurt the viability of the traditional resources so they are going away for everyone.

content: Quote from: tggzzz on March 22, 2024, 09:57:56 pmI can appreciate that, though I have developed a tendency to jump through a video to the middle or the end to start making an evaluation. I can quickly reject videos if I don't see any meat several minutes in.By the way, an amusing case of honest and critical reviews is Matthias Wandel reviewing a Vevor metal lathe. He said it had poor tolerances, mechanical problems, poor finish and inaccurate documentation. He asked Vevor if they were going to be upset with his review? They said, "No, not at all, keep being honest. We are selling at a price point, and all of the imperfections you report are to be expected at this price. We are not pretending anything different."

content: Quote from: IanB on March 22, 2024, 11:54:47 pmStrangely I can't. Well I can quickly jump to a random spot, but then it takes too much time to figure out the current context and listen to several sentences. Maybe 1 minute each time I skip. That's doubly true where you skip to a visual of a datasheet or slide, with a talking head explaining the relevant bits of the data sheet or slide. Better to just read the damn data sheet!Even in a good video I would need to do that several times to find the nuggets that make the rest of the video worthwhile.There's a lot to be said for formal scientific papers, which have an explicit abstract at the front, and conclusions at the end. You only have to read the middle if they contain something interestinfg or surprising.

I would have added a couple things and possibly made it unnecessarily more complicated for beginners.I have a crate full of old instruments of that type... which will probably never see use again.https://www.eevblog.com/forum/chat/show-your-multimeter!/msg5401139/#msg5401139
