EEVblog #981 - Introduction To Digital Logic

[bktemp]

You should expand the poll to include the other variants.
I don't like the DaveCAD variant, but I like the talking head. So I would vote for virtual whiteboard + talking head. It doesn't add any significant information to the video, but it makes it more pleasant to watch if you see who is talking to you.
DaveCAD is good for some small schematics near a practical demonstration, but I don't like it for more detailed fundamental videos.

   Two thumbs up for the new format Dave, I like it a lot better than the old whiteboard lectures because it's easier to see. I couldn't personally make use of the information in this one as I have been working with logic for decades but I know that this stuff will be of use to the beginners.

Oh, and keep it on this channel please.

[oldnewb]

Even though it consumes screen space, it's still nice to see the person that's talking.  I think it's easier to lose the viewer's attention when there's nothing but writing and a disembodied voice.

And DaveCAD is a fun gimmick, but I don't think it adds anything in exchange for the screen space it uses.

[nugglix]

I voted for "keep it at the main channel" for a very simple reason:
It's new and as it looks like now even Dave can't say if this format will stay.
So why bother and waste time on it now?

As Dave explained above, this format is a more complex to produce.
So I think it would be a good idea to see if this holds true for the following
episodes or if routine and familarization can reduce this kind of cost.

In general I like the idea of more basic topics -- but that's because I'm a beginner.
Length and the typical Dave style made this a nice watch and I'd really like to see more
episodes done this way -- especially on more analog things (but thats me again).

Loved the basics. Good for ppl who are starting with electronics like myself. I'd love to see more of the basics like op-amp with real life examples but not complex. I would name these series of tutorials as THE DAVE SCHOOL OF ELECTRONICS [emoji4]

And the white board idea is very good too. Helps with following the cursor as you point out stuffs while explaining. If the cursor color  was black or something that pops out it be even easier to follow it.

How are you liking the Wacom Dave? Seems like you've gotten the hang of it pretty quick.

[Barny]

Thanks for the video.

I would watch the video on every channel.
But I would prefer when it would stay on the main channel, because its easier to find when you search for it later.

If someone don't want to get educated, he / she haven't to watch it.

And as a bonus, Dave will get more money when the videos get posted at the main channel.

good old logic circuits    my suggestion is to make a video on diode steering TTL or cmos logic inside the gates.

as for the video presentation, this is good, but add a dark border to improve contrast or invert to a blackboard. you may have too much on screen white over time. 
note- that a live eevblog whiteboard video has a border and Dave's head on the side for added contrast to the board white. also in live video, a whiteboard is often seen as off-white. or 90% - 80% white level. 
so to fix, IMO the border need only be 5% to 10% darker.  pre plan your freehand drawing spacing so you do not end up squashing / going off screen or a big blank space. save time erasing / rubbing off, if you can? just cut or edit out to save time.
I also like the use of inserted schematic art images. to save time & show the more complicated diagram blocks.
as its not a whiteboard you can add more color, in your inserted schematic art images , but gust a suggestion,
colors do change on a background. yellow will disappear & dark blue can look almost black. but invert to a blackboard and your red needs to be pink to look red on a dark background. yellow will look faded or white.
do you need a separate channel? not IMO.

That's why pure white is very convenient.

How so?
Surely a new channel with just tutorial videos is better to search?

[bibz]

Thought it was bloody awesome! Same channel different channel doesn't matter, hit the sub button once, get everything. Its funny how some people can't grasp the 'I don't have to watch every second of every video if I'm not interested' but then again I'm glad theres different types in the world.

[JPortici]

I think it's more a 2nd channel type of content.. you are not being seen in the video, you are doing voice overs...

the davecad one made me chuckle. really liked it

Yeah, I don't get it either.
The 2nd channel has benefits though:
a) If anything it's a good experiment to see how many people would actually sign up to a tutorial only channel, I'm kinda curious.
b) People who sign up get what they want every time. This leads to higher sub/view ratios which the Google algorithm really likes. This might help snowball the channel and also get it further up in the rankings than just having it buried in my main channel.
c) The other recommended videos from the channel will always be tutorials, i.e. exactly what people signed up for.
d) No inevitable complaints about flooding my main channel.

I'm an old scatterbrain.
I've big problems to remember where I heard the information.
When I've to remember which person on which channel the information is placed, I'm lost.

But, I'm ok with a separate channel.
I hope, the old fundamental-videos will be shown on the new channel too.

[Brumby]

I wouldn't get too precious about presentation 'tweaks'.  One of the main reasons is very simple.  Time.

I would not want to advance any suggestion that will take additional effort - without there being a fairly significant benefit.  "Dressing things up" could end up adding production time for every episode.  The result would be a time impact on everything else for Dave.

I think the people who would be watching would more likely be interested in the content.

Keep it simple - and keep them coming.

A separate channel would seem appropriate.


JMHO

[rrinker]

 I say, keep it on the main channel. Too many different channels I fear would lead to dilution - those that like tutorials the most will subscribe only to that channel, those that like teardowns the most would only subscribe to that channel. I only have my one little channel that maybe 3 people subscribed to to watch my train videos, so I may have it all wrong about how YouTube works when you create multiple channels - if it doesn't matter and what actually counts is the aggregate of all people signing up for all your channels, then I suppose it wouldn't matter.
 Perhaps after the whole additional host thing settles out and there's an EEVBlog Empire (just don't go all Palpatine) with a whole herd of hosts each producing content - then I can see multiple channels. Original EEVBlog channel with you only (and guests), and a channel for each of the various specialist topics that each host covers.
 For white screen tutorials like this - where appropriate, maybe add some camera work showing a practical demonstration of the fundamentals being explained on the drawing pad. Nothing fancy, quick and dirty breadboard level experiment to demonstrate the topic. In the event that a demo circuit would be somewhat complex, it doesn't even have to be built on camera, you could have it prepared ahead of time and bring it into the shot. Shooting sequence wouldn't matter, then demo parts could be recorded before or after the lesson, and inserted in the final cut where needed. It's hard to judge since in this case you happened to pick a topic I know very well (but I watched anyway), but for something I'm less familiar with, seeing an operating example of the theory being presented definitely improves my comprehension.

Great video Dave, surprised that nobody noted that:
(A AND B) OR (NOT A AND B AND C)
could probably be simplified as:
1. (A AND B) OR (B AND C)
Then if B is 0 then both 'AND' members are 0 then result is 0, hence it is equivalent to
2.  B AND (A OR C)

Notes:
a. parenthesis are optional in 1 but it reads better
b. to get a feel of intuitive simplificaiton of 1 ; think of 1 as if A is true then [whatever] else if A is not true then whatever can be simplified by a simple if else. (no second if needed)

I mentioned a 2nd part is needed on Demorgan's theorem and other simplification techniques.
Was too much for this video.

[fab672000]

I hope i did not spoil (part of ) the suspense of next video then

[lem_ix]

DaveCAD has an EEVblog vibe, stick with that

[MickF]

Great video Dave, I would like to see many more on a separate channel. The electronic whiteboard is great. Would like to see your face at the beginning & end of the Tutorial, but not picture in picture.

[Windfall]

I'd say throw everything on the one channel. It's all in the labeling (descriptive titles, telling screenshots).

I doubt that having a separately themed channel would make many people watch every one of the videos on that channel. Personally, I only watch all the mailbags (because they're unpredictably interesting). I don't watch any of the other 'themed' stuff consistently, for various reasons. Who does ?

[mtdoc]

Big thumbs up on the concept.

Keep it on the main channel - don't dilute your brand.

Show your face at the beginning and end but no picture in picture - it distracts from the content. Content is king!

[Mr. Scram]

How so?

The current two channels do not really seem to have a clear distinction, especially if you take older videos into account, which makes searching for something you have seen a while back a bit hit and miss. Adding another channel would possibly compound that.

Of course, this has to do with the format being tweaked and adjusted over time, but I have to admit that the current blog, blab, bant and second channel distinction is not really obvious to me either. Well, maybe the blogs, but the rest often seem interchangeable. I have wondered about that before.
