EEVblog #981 - Introduction To Digital Logic

[EEVblog]

NEW screencast type tutorial!
Let me know what you think.
NOTE: The plan is at least several of these tutorial videos per week consistently. So on my main channel that frequency could swamp the other content, hence considering a new channel.

An introduction to digital logic, digital vs analog, logic gates, logical operators, truth tables, timing diagrams, and the dreaded boolean algebra.

I would put it on the main channel but use a different name like EEVwhiteboard to make it clear it is a video without any actual camera footage. So people shouldn't expect to see Dave on this type of video.
It looks quite similar to previous whitheboard videos, so I think the overall style is ok.

Interesting.  Twitter/Youtube seems to have recognised the video as Danish 

Enjoyed the video.  It's obviously basic stuff but I'm sure there is demand and you have to start somewhere.  Looking forward to you putting on your flip flops.

IMHO It fits nicely on the channel.  I was only watching "EEVblog #262 - World's Simplest Soft Latching Power Switch Circuit" earlier as I wanted to know a little bit about latches.  Nice to have stuff like this in the back catalog.

I've not watched the whole video yet but I think it's a good idea  It worked well for the Khan Academy videos and others. It would be nice to have it mixed with bench stuff where appropriate, but as the video pointed out there's no reason that would be mutually exclusive.

I don't have any preference as to whether it goes on main channel or a second channel so I said main channel for the poll since there was no option for like it but don't care which channel.

I would watch these tutorials whichever channel they were on but I do like the idea of a dedicated cannel where one could study the subject matter without being distracted by other content

Youtube poll is currently 75% keep on the main channel 
Perhaps I'm in a unique position to know that my audience will complain and scream blue murder if they suddenly see 2-3 of these videos popping up every week and swamping the other content. Even if the frequency and variety of the other content actually remains the same.
I might start the new channel anyway and upload to both for now perhaps.
Some have suggested playlists, and of course I'll do that, but most people actually don't use playlists, and Youtube's handing of them is kinda poor.

That's the idea. You only get tutorial content on the other channel. Same thing every time.

It will be interesting to see how this develops. I look forward to a repository that I can go back to as and when my understanding catches up with your teachings.

EEVFundamentals/EEVSchool. I think people would be more likely to complain if there were several uploaded per week, in which case a new channel would fit.

Probably going against the flow here but I prefer you with a whiteboard as there's far more interaction and personality than a bland soulless pad.

On the whiteboard you can be more expressive and it's also easier to track your hand as the eye will naturally track to it within the conversational flow whereas on this pad/screencast one has to focus on tracking the cursor. This would be the case even if the cursor was made more prominent than in the video above. Not to say the pad is all bad as I'm sure there are items easier to show on the pad but, imho, many things are better on the whiteboard.

As for the tutorials    and more please .. Not bothered which channel but ideally nicely indexed with playlists.
Your style of presentation with practical demonstration of both what works and what doesn't (traps for young players) is far better than any other style.

Please don't become another bland soulless theory only maths-fest channel - there are several already.

Nicely explained Dave.

I did something similar for a group of work mates who call themselves IT geeks, but did not know anything about digital logic..  Go figure!! Where do we get these people. 

A few of them found it hard to grasp how such simple gates could form a complex device like a CPU.
I used the analogy of Lego bricks. With only 4 different kinds of Lego bricks you can make virtually anything you like, as long as you have enough of them!!


Maybe have a picture in picture included in these sorts of videos. It would be nice to see your smiling face in a corner of the screen instead of just drawings 'magically' appearing. Everyone's a critic! Sorry.

I support the new idea. Watching Dave at a whiteboard or behind a DaveCAD drawing is bit more interesting to watch but if the new way fits Dave more I'm still okay and if the topic is interesting to me i will watch it. I did find this video interesting and watched it from the start to end even though there was nothing new to me... it was still interesting to watch like most Dave videos are.

Unfortunately you can't have both.
Whiteboard tutorials take more messing around, more setup time, more execution time, and they are less flexible.
This means:
a) Less enthusiam to do them
and
b) Less time to do them.

Please don't become another bland soulless theory only maths-fest channel - there are several already.

That's why I suggested a new channel.

I like the idea of a picture in picture format but that might be problematic for dave to produce.

I've had complaints before that this is distracting. Now it seems many people are saying they prefer this?

It's a bit messy with framing and eye angle, and you can't physically see if your face is covering any of the image.
I might give it go and see which one people prefer.

I liked it,very condensed. Not sure if newbies that look for these tutorials the most get put off by the other videos? Probably fine if the playlists are organized.

Maybe add your head for people that like the personal touch? I don't really care but can imagine the white background can test some people's concentration.

Would be nice if there was at least a short clip of the logic ICs in action but I think people would pass on that if it would reduce the frequency of these videos.

I like it just fine. Yea you would put it in the playlist but people will still find it in other ways easily so they will be found by people needing the tutorial.

Screencast then .. could you try some different cursors please?. Thin black cross on thick black text was sometimes tricky to see. Understand it might be the best for you when working though.

Please keep the practical demonstration and Traps for Youngs Players.
It's your Unique Selling Point (urgh, hate marketing wankery) and what will differentiate you from the KhanAcademy style tutorials.

That is fixed in the Smoothdraw program I believe.

But sometimes (often) you just need to present the theory.

Now that you have the presentation sorted, how about a couple of lectures from the UNSW EE curriculum?

Edit:
Or University of Sydney. Take your pick:  https://cusp.sydney.edu.au/students/view-degree-page/degree_id/449

I always get a chuckle when I see "Fundamentals of Electrical and Electronic Engineering" in the 2nd year of the course.
And I just did a 2nd year video

I thought that was pretty grim too. There's got to be some bone they can throw to the n00bs in year 1.

[EEVblog]

I'm going to try a new idea for this, I'll do a demo on the 2nd channel and see how it works
