First!  :-DD

Edit: Really, though, I like this new segment. It's nice to see you answering questions directly even if the comments found on Youtube aren't exactly of the highest quality on average. Most content creators completely ignore comments or even disable them.

Good luck with your surgery, by the way.

Disabling comments is just stupid. Ignore them totally if you don't like them, but comments are essential for a channels growth and success.

Well, to the quality of the content question. I do agree that video quality dropped significantly.

If some interesting thing takes more than 5 minutes to setup, forget it, it is not happening. More and more things get tabled for later, which never happens. This is understandable, since you need to make scheduled videos, but it is also very apparent and is not looking good.

More and more videos (including this one) are of a type that is easy to make (comparatively, of course) - talking head or screen capture.

Edit: Just for comparison, quality of Mike's or Micah's videos is superb, but those videos are rare, but they are way more enjoyable.

I guess it is just a different style and the need to make some money out of it. Unlike Mike's videos, I mostly "watch" Dave's videos in the background without paying much attention, anyway, there is just not enough "good stuff" there to warrant full attention.

I skip through a lot of videos.  Is there really a need to make them a certain time content?  Its a video.  If there is something a beginner doesn't understand, they can back up.

One thing that I've been missing on your channel recently are videos where you do design work. Those used to be interesting.

Nice segment.

As I wrote over @ youtube:
Quote from: what I wrote on youtube
Any chance you may want to talk about Power Supplys and Electronics a bit more?
And especially take a look at some higher End ATX PSUs?

And also tell something about the importance of voltage regulation and ripple & noise as well as output protection.

I'm asking because some ATX PSUs, even in the higher price range, do not have working output protection. So it's entirely possible to burn a DC-DC module. Or they don't switch off when they are heavily overloaded...?

an example of bad protections and another example is the EVGA 550GS...

I won't start to bother you on capacitors (yet), but please, please take a look at the datasheet of the capacitor.
TDK Lambda held a webinar here in Germany some time ago, with Conrad.de where the question if japanese capacitors are really better or not came up.
He answered that it's not and it all depends on what you want and what you are willing to pay for.

As for companys like Teapo (wich aren't that bad by the way), they are mostly rated for the worst low ESR capacitors they sell and most japanese companys don't have capacitors in that range...

I would really be happy if you'd take a look at those things and make a short video about it!

I like the idea of this video.  Giving a video response to questions/comments is a great way to maintain a solid connection to your audience.  Much like picture-in-picture.  ;D  Videos work much better than typed text.  Text lacks the ability to convey expression outside of a couple of formatting options.  I liken communication via text as trying to appreciate opera via teletype.

The only criticism I would make is that some of the responses went on for longer than I felt was necessary, sometimes repeating ideas.  I realise this will happen with unscripted content, but just something I felt was more prominent than I felt it should be.  I did notice there were several editing cuts (so one wonders how long you did spend on the shoot) but I do appreciate the effort to trim it down.


Like any of my comments - throw them into the mix and see what sticks to the wall.

There's something in me that says that answering troll comments is pointless and a loss of time because they'll of course never learn from it anyway or not even read it (definition of a troll...), but in this form it could have the advantage of being educational for others in a much more useful way than a written reply.

About the voice... you just get used to it I guess ;D I had a very hard time back when I discovered the channel a couple of years ago, but the content was interesting enough to "put up with it"... it doesn't disturb me anymore.

Dave,

at first, I hope you'll get better quickly, after your cruciate ligament repair.
(What about a teardown and repair video of your knee, during surgery  ;D ;D ;D ? )
Weeks or months w/o sports (afterwards), that's really tough, so I can really feel for you, if you were grumpy the next time..

This new format is great, as you're more vivid in this video.. and this is more entertaining, for me, at least compared to the old-style mailbag videos..

I think this format has potential, as it allows Dave to address e.g. recurrent questions, and to answer to viewers that may not be interested to e.g. participate to the forum threads.

I hope that it won't be used only as a defence from various accusations and negative comments, but possibly also to add extra notes to previous EEVblog videos (interesting stuff that was left off a video, quick updates, etc.)

Knowing Mr. Wafflemaster's habits, perhaps here is where I'd welcome an 'extreme' cut: no more than e.g. 2 minutes to answer any comment  ;)

I like the comments and answers concept.

The best thing is you take the time to answer questions. It’s a valuable source of information.
When I started in electronics there was no internet and I didn’t know anyone that could help me with my questions. I wish I had these resources back then.

Dave, big :-+ to you.

If I may offer an opinion of a new to eevblog and newbie to electronics with a background in software (systems and compilers)....

I found your channel while working my way through AoE about a year ago and have been hooked since. Your video on op-amps was the ticket for that concept to finally register in my little pea brain. I would like to see more fundamentals, and you're correct that there are already a lot of those on the youtubes, but you do them so much better.

Maybe it's because I've only been watching them for a year (and still have a few more older episodes to watch), but I like the way you've been doing the mailbag and wasn't especially fond of the turbo version. That segment is so much about your personality and our entertainment, please do what you feel is natural and I'm sure it will work.

I don't see the justification for criticism of slipping quality in recent videos. I've been watching older videos along with the latest and it seems, if anything, quality has improved. The recent SA teardown was phenomenal as others have said. You have been experimenting, it seems, but I think that's great if you are doing it for yourself and not to please a few cranky viewers.

I really enjoy the interviews and especially the field trips. You offer an interesting perspective and you ask great questions. I think you show the "right" balance of intelligence; not making the video about how smart you are, but you show just enough to get your subject to talk geek and let them be the expert. Viewers underestimate how hard that is.

There is a comment above regarding more design work. I agree - would love to see more about your thought processes during the design phase. Not sure how to make that work in any volume of videos, though.

I guess my only real criticism is that you seem to overweigh negative feedback lately. You created a winning formula, Dave. Keep up the great work.

The channel used to have a lot more "hands-on" electronics and just the occasional blah video. That seems to have reversed over time, so it's now a lot of blah videos, which are a probably a lot easier to make, with the occasional hands-on. For me it has become less interesting that way, but I guess others seem to like it.

Things evolve.  Things change.  Some people will like the changes and subscriber numbers will go up.  Some people won't and the numbers will go down.

It's swings and roundabouts.

It's a matter for any blogger to assess the consequences of change - and while there may be some who bow out, if the overall numbers increase, then the change is a good move.  (IMHO)

As others have said, the SA teardown with the extra graphics effort was well worth it.  It doesn't take an Einstein to appreciate just how much more effort was involved and Dave's comment about this not being really warranted for a lot of gear is just simple pragmatism and practicality.

You really aren't going to get a whole new understanding doing this on a DMM, for example.

That how it feels but actually if you look back there were simply fewer videos. The "blah" videos are pretty much in addition to the usual content leading to more videos, rather than less usual content.
Easy to be biased, especially since for example when I found the channel I watched a load of videos, but those had actually been posted over years.

Here's something from the ESA:

Note the mosquito trapped in the prepreg on page 4...

But the jist of the paper concerns itself with factors that contribute to electromigration. I was talking to Dennis over at the Altium forum (long timer EE) and he had mentioned something about this a while ago.

Surprising that even Class 3 stuff is susceptible to this - not just asian made happy meal toys for McD's.

Many have said this over the years, so at one point I went back and analysed 100 or my earliest videos to 100 of the later videos (around 500-600 IIRC) and the result was that people were in fact biased, in reality there was no change in the frequency of certain types of videos. I simply added more  videos types, and people tend to remember certain videos and think I did more of them than I actually did. The data is someone on the forum....

Well Kilrah does have a point. If I look back in your playlist history, from the last year I see less in depth electronics/tech videos than 2-3 years ago.
Nowadays it's mostly mailbag, a couple of teardowns and some general tech news.
I guess Dave has the numbers (hopefully he keeps them up in categories) to see how many in depth tech videos he has over a certain period of time.
I can do it myself, but by hand, that's an awful lot of work.
The amount of videos Dave uploads in a year, is pretty consistent.

If we go a year back from now (so from #906-#774) he uploaded 132 EEVBlogs.
The year before that (#773-646) it was 127 videos.
From #645-501 was 144 videos
From #500-325 where 175 videos (a bit higher for some reason)
And #324-192 = 132 videos
#191-102 = 89 videos
And so from the start 102 videos.

Which is an average of 128±5 videos and a dispersion of around 30 (or 60 if you like to use 2 sigma)
This also brings me already to a conclusion that the earliest 100 and last 100 videos is not very representative.
To fully investigate how many tech videos there are it would be even better to divide every bit by two, and so look back over 66 videos.
Which represents roughly half a year. Better would be to use actual dates instead (but for me that means that I need to open a lot of videos and check the dates).

I do have to say that there was a lot of interesting stuff in the last few teardowns lately.
On the other hand, most of the time it's nothing more than just summing up parts and if you have seen two scopes/analysers, you have seen almost all of them.

Anyhow, we can go far into this discussion, at the end you'll always end up discussing and debating about taste, feeling and expectations.
I guess we just have to see it as healthy critique to keep each other sharp, which you can take or leave. :) ;)

Interesting, and I liked the segment.

I will say that, regarding the student who wrote about the future of EE -- I think that question could use a LOT more thought. It is this EE's opinion that electrical engineering employment is indeed in decline, at least in the USA, and I suspect, other development countries. It's not that EE skills are not helpful, or that understanding electronics, systems, signals, etc, are not useful. They are all useful and will continue to be. But I think more and more of the work, in particular, the high PAYING work, will migrate to software people who understand the hardware "well enough." Which is fine. The fact is that EEs make good firmware engineers.

I think someone smart, with a solid EE background and a willingness to adapt throughout your entire career, should always find employment, but over time I suspect it will be less and less directly related to EE.

I mostly know Silicon Valley. I can assure you, semiconductor employment is way down here. Mostly, it is through attrition, as people retire and move on, but nobody is hiring loads of young engineers to design chips anymore. It makes sense. Though volumes continue to grow, margins continue to shrink, and chip starts are way down, because "big" SOCs with lots of peripherals can fill many niches that used to require custom or semicustom parts.

I'm not really a board guy, but speaking of SOCs, I think the proliferation of very capable parts with lots of cool peripherals is also obviating a lot of would-have-been design work. It's gotten really easy to plop down a uC and hook up a few things over serial links and a few standard interfaces. In essence, a lot of board design work has been slurped into the chips, where one team designs it once rather than every board designer doing it again. There might be more boards being designed than ever, but the effort per board seems to be going down fast, and that's actually not great for employment. Like you, I take apart a lot of stuff, and I'm blown away lately not by how complex many modern high volume boards are, but how dead simple they are.

I do hold out some hope that as Moore's law sunsets -- and it really is sunseting this time -- there will be renewed interest in creative EE design, as natural evolution in performance and capacity won't solve problems "automatically." That will perhaps mean more novel architectures, use of FPGAs, close HW/SW codesign, etc.

Of course, SV is booming, but it's just not driven by electronics. I suspect that there is a lot of growth in Asia and in development countries.

Here is what the US Bureau of Labor Statistics has to say about the 2014-2024 job outlook for EEs:
http://www.bls.gov/ooh/architecture-and-engineering/electrical-and-electronics-engineers.htm#tab-6

Note that over a 10 year period they are predicting essentially no growth for EE's at all. None. Compare this to employment overall, in which the predict 7% growth.

Finally, I think we all tend to think of EEs as the "model EE": clever, curious, and energetic -- and stays that way for 40+ years. But let's remind ourselves that 1/2 of EEs are below median. (not among the population generally, but among the population of EEs) If you know the student in question, you can make an informed assessment about that person's prospects, but when you are answering a generic question about prospects for generic EEs, I think the right picture to have in mind is that of the middling engineer, not a particularly good one. Will that person survive for a full career as an EE?

I'm not saying at all that EE is a bad career, and for all I know the number of people getting EE degrees is going down faster than employment, so that the prospects for an EE graduate are actually quite good, but it is important for students to know the state of affairs.

first off, i love how you included all of the negative comments. youtube is full of ppl who take themselves way too seriously.

second, on the unsubscribing for "bad content", honestly, i dont watch all of your vids anymore, partially because of the length of them. sometimes on days like today ill go and watch some of the longer ones that i had less interest in because of the title, but you have been putting out more content than when you started, so if the title dosent grab me right away, i may likely not watch a video. im not saying that is "bad content" but i can maybe see where he is coming from. BUT THAT SAID, i do think your channel has changed. your first videos, you seemed..... timid??..... idk, like it was forced. it seems since then you have become much more comfortable at it and your love of what your doing shows through, and i think it makes the video a LOT better. i dont think you should change what youre doing and lose that enthusiasm.

i can watch thousands of boring videos of people with annoying voices tearing down electronics, but your enthusiasm for it make your videos not the same old boring shit, which is why i, and im sure a lot of your viewers, choose your channel.  :-+
