EEVacademy | Digital Design Series Part 1 - Introduction To Digital Logic

[@missing1person]

I would love to see eevAcadmey

[@AnalogueGround]

I don't think Dave should do this on a regular basis - there are others on KZbin who do it much better - Ben Eater for instance. Don't get me wrong, what Dave does is superb - nearly 1000 videos uploaded can't be bad, but projects get started and forgotten (Lab PSU, Nixie Display) - Teardown Tuesday and Mailbag Monday are now anytime it suits! This sounds overly critical but it's not intended as such, it's just that when you spread yourself too thinly I would imagine that it would be difficult to commit to something like an eevAcademy. 'Students' could be let down by content suddenly not appearing because something in the dumpster was more important. I think Dave does what Dave does best and we expect too much from him. Nearly 1000 videos of self opinionated and informative technobabble is a great achievement.

[@michaelhawthorne8696]

AnalogueGround : I think you have a valid point, he does have 2 children now (at the time of writing) which weren't there at the beginning, (Gosh, remember that, the video quality.....) I have to say though, what he produces (Consider the family extras) is the best on youtube to date. He is an engineer with a wealth of knowledge and what he sends out is easier to remember because it's so visual..... text in a book is flat and not always clear. Many people do teardowns and I haven't seen them all but I don't think I need to, Dave provides excellent information and that will do.

[@TopherSnags]

Dave did a survey just days ago (go check it out i think its on the second channel)... there is a huge demand for these tutorial videos.

[@ramzi1957]

yeah and adder and demonstrate that every logic can be done with NAND. I think more people should be interested in low level logic :) it really helps on conservative programing and also general programing where you don't want to rely on "what if" it works.

[@mancelprince97]

Why is this reply exactly the same as "svampebob007" replied a month ago? Even the :) is the same. Are you the same person or is one of you a robot?

[@andyjopson4402]

A logician's wife is having a baby. The doctor immediately hands the newborn to the dad. The wife says, "Is it a boy or a girl?" The logician says, "Yes.". ;)

[@jeremiahfourtwenty]

Thanks for the logic video Dave. I am back in school at 42 and every video helps.

[@LazerLord10]

As I sit here nearly finishing up my first computer engineering course, this video is great!

[@wingnut2009100]

yes more. took a technical course on digital, forgot most of it. this is a good refresher.

[@nickandpammorano9346]

I agree! Sign me up and put me at the top of the list!

[@WereCatf]

This is probably the first time Dave talks about a topic that I actually already know and that didn't go over my head :D

[@AdamTheAd-vanc3d]

Sweet mother of jeeesus !!! , this has got to be the most easiest to follow videos on logic gates. Your explanation has taught me something which ive been trying to understand for yeeeears in just over half an hour !!! Fantastic video Dave .👍👍

[@PerBuch]

wow.. Dave Cad going digital :-)

[@FLyyyT_]

beat me to it. good i made sure lol.

[@khronscave]

Same here :P

[@AJ-kj1go]

I one of the (many) people who love your channel but lack the background in EE I loved this.

[@unconsciousALLY]

thank you sooooo much I was so lost and frustrated at my comp organization & architecture class because they don't do hardly any in class examples. You are a live saver thank you so very much

[@duncan8238]

Fantastic stuff mate, thanks so much... 20 years since I studied this stuff and now finally I am starting a job that requires me to know it... I'm well chuffed I found this channel!

[@LOTFI__TECH]

man! you've put me 20 years back when i was doing this in the university . i like it !!!!!!!!!!!!!!!!!

[@amicklich6729]

I think it works great for tutorial videos. It's a good platform for when you don't want to be distracted by various goings on in the background. It's just you and the material face to face.

[@mardav1545]

I'm finally getting the gist of digital logic. Just looking at it in a book looks like gibberish to me. Thanks Dave and keep up the good work and add another and another.

[@kathyquinlan5922]

Ahhhhh This brought back memories from Tech when I did my apprenticeship in Electronic servicing Digital Systems :) We learnt the 6502 processor and programmed on embedded systems in machine code (write the program, hand compile, type the program in with a hex keypad in a monitor shell). I would love to go back to those days.... DSE still sold electronics, EA still had Projects, Silicon Chip had great projects too. Near the end of year 4 (I did a second 3rd year subject to pick up a second area which was radio and TV servicing (got me out of work for 1 day a week) The Basic Stamp was released.... Feels like it was only yesterday ;)

[@larrylonger9892]

Big thumbs up for this and all the other tutorials you made Dave. Best wishes for you and your family and all the best for your further future from me to you.

[@richardgoebel226]

How ever you choose to present your tutorials I still learn from them. I look forward to Part 2 on Basic Digital.

[@guilherm502]

It could be called "EEVersity"

[@shockwavecity]

This reminds me of the Forrest Mims electronics books i read when i was a kid. Love the hand drawn illustrations.

[@soarster]

Please keep it up, you seem to be getting through in a clear and concise manner that I crave. Just found your channel recently and have been bringing lately.

[@wolvenar]

I most certainly want to see more of this kind of video. amazing teaching

[@JimK0QJC]

I like it. Dave's style is refreshing.

[@tedvanmatje]

hi Dave, the beauty about this new format is that you don't need to be in your lab to present it and it can all be quickly done from home. the way I see it, it's a win-win for all - we get our brainfood and you get valuable time with the family. good stuff, mate! boolean algebra brings back memories. still on the fence, ref. a new channel. just do what you do and all will be gravy. :)

[@fish0741]

Love this, Hope it becomes a regular, separate channel. Call it EEV-Ed or EEV-Concepts Thanks for all your efforts love your channel. I've been a Appliance Repair Tech for 30 yrs. and learn something all the time. Most Appl. are becoming all electronic so learning this is very useful.

[@frankbuss]

Good idea with these tutorial video style. It is better than your normal whiteboard, because the viewer can always see everything and much clearer, and your voice doesn't change all the time because you are turning your head like with the whiteboard, which was a bit annoying in your videos. This video could be uploaded right to Khan Academy :-) Maybe just post it in your main channel, but with different labeling. Regarding the content of this video I didn't learn anything and I just skipped forward, but no wonder because I programmed small and big FPGAs for some years already and I do a lot of retro-computing electronics, but analog basics videos would be very useful for me. Or advanced digital stuff, like explaining meta-stability and how to avoid it etc.

[@shadow7037932]

I would totally back a Kickstarter/crowdfunding for Dave to make some solid EE videos ranging from (beginner to advanced concepts) to put up on Kahn Academy. Dave explains things a lot better than like 90% of the professors I had in college.

[@GrantsPassTVRepair]

I appreciate the way you simplified this. I look forward to more of this nature. Thanks!

[@banananaa]

This video practically summarized a week worth of lectures when I studied to be an electrician. This hand drawn stuff reminds me of all the fun watching my classmates struggling with the subject. (Because of our incompetent teatcher who got fired after a single period.) I'll have to check if I've got some of the schematics left from the end of the course and post them on the forum as some of them were quite fun to solve.

[@DrakkarCalethiel]

EEVBlog uploaded a new... Instantly opens KZbin. Very good idea with the tablet. Much better than the whiteboard.

[@Electrolab28Ag]

Love it. This exactly what some of us who are newbie's to electronic need. I would definitely like to see more. Not necessarily on a different channel. Thanks for the lesson.

[@jaywalkah]

Love it, Dave. Trying to self-learn my way up into engineering (can't afford Uni) so if I'm able to do that, a portion of my salary will go towards your channel. Thanks for everything you do!

[@Orbis92]

I really like this format, but I hope you do beginners and advanced stuff :)

[@WereCatf]

As a fellow beginner, I too hope for more beginner-stuff :)

[@TomStorey96]

That was about as beginner as you could get. You can't really explain logic gates any simpler! But if you still need more, or perhaps Dave's style doesn't talk to you, try Ben Eater. He's got some great videos on logic.

[@jonka1]

Very well explained as always. Thank you for wanting to do this.

[@benedictnothing]

That was good. I needed a quick refresher on this stuff. Cheers!

[@theniklas]

I like this, tho I would personally prefer a darker background. :)

[@EEVblog]

The problem with a black background is that I'll likely be pasting in datasheet stuff, and they all have white background.

[@deadbugengineering3330]

Most PDF-readers can invert colors. Check the "Accessibility" tab to select "use high-contrast colors".

[@Stereotype3]

It doesn't have to be black either. Just a grey/brownish tone is so much easier on the eyes.

[@craigtucker777]

white is appropriate colour for this kind of continent

[@dermihai]

Maxamps check Khan Academy

[@ArdaX95]

yes please we need more tutorials, a dedicated tutorial youtube channel would be great! thanks Dave :D

[@eddiespencer1]

Probably the easiest to understand explanation I've seen. Thanks for doing this, man!

[@JLSoftware]

Appreciate the post of introductory material.

[@ingenierocristian]

Please, continue with this awesome job with the EEVacademy!

[@dosgos]

Really like the Wacom whiteboard. Great lecture as well. Learned a lot today

[@LordGryllwotth]

I liked it! Feels like school again. Refreshing.

[@nielsgissel6134]

EEV you have a hidden talent in drawing ;) I love your video. You make Boolean logics easy ...

[@colcaboom1626]

Love it Dave, keep it up. One idea for these is tips on how to pickup freshly made china arduino/pi copies and make complete systems with them, mostly the dos and donts for that. :)

[@Spender604]

No problem at all with this new format, and a very good lesson at that!

[@deanrubine2955]

I've known this stuff for 40 years. I'm in it for the interjections. Yes bingo! Beauty!

[@billmoran3812]

Excellent! I like the format. Perhaps a separate channel to allow those of us who are serious about learning to subscribe. One suggestion, it would speed up the presentation a bit if some portions like diagrams and truth tables were done off camera like you do with the whiteboard. Very worthwhile content. Digital logic only existed as theory when I was a student. My only foray into that world in the 60's was making a crude calculator that used a dozen or so 12AX7 vacuum tubes.

[@Pumoneon]

Light-on-dark color scheme please!! MY EYES ARE BURNINGGGGGG. Nice video Dave! Thanks!!

[@trent33511]

Dave, liked the style and the information. Absolutely keep it up!

[@insoft_uk]

Maybe try a blueboard next time giving it a EEVBlog signature , also picture in picture of you talking in the corner to give it a bit of life to the tutorial.

[@ElixTwo]

I love it!!! Please do more! Thanks Dave!

[@yourcurtainsareugly]

This is more my style than Crash Course Computer Science. It's more in-depth and doesn't gloss over the math. I loved my discrete math class. I remember in particular having fun with contrapositives: "That which does not make me stronger kills me", "If you can't get out of the kitchen, stand the heat".

[@jjkosinski]

Great. Cannot wait til the next video about logic. Thank you. Gave thumbs up.

[@rasimbot]

Classic format with markerboard and facial expression is better for me

[@DragonsDenCreations]

Like it very much. Easier to see and hear as opposed to the regular whiteboard. Plus the datasheets and other paste-ins drop more naturally onto the screen. And there is the added bonus of fewer distractions from you moving around and such. I also have a feeling that this format is much easier on you to record and edit. So thumbs up all the way.

[@SuprSi]

That was an awesome lesson. Easy to follow, I like the whiteboard style delivery with your wacom tablet. I'm looking forward to next one about simplifying logic circuits. Thank you Dave!

[@Knight_Astolfo]

Seems like good main channel content. Like a continuation of the earlier basic videos but digital; rather than the analog whiteboard.

[@shaunmorgan372]

Good review of gates, defiantly expand to the rest of the topics, karnaugh maps and simplification, etc!

[@taiwanjohn]

I like these tutorials, and the Wacom tablet seems to work just fine. Also, please keep them on the main channel (so I don't have to subscribe to multiple channels). Thanks!

[@andrewsharp3945]

I enjoyed it, a few verbal slip-ups but it could work really well! I prefer digital to analogue anyway. It can stay on the same channel because it won't be long before you start to get practical and build some digital circuits. Great job Dave!

[@the3dom]

Excellent video. I wish I have this video 20+ years ago. Separate channel 'just' for this will be great and one video per week.

[@EEVblog]

It would be a couple per week.

[@marcusbaker6042]

I like this Dave. If I remember, you can load in pre-made templates and add your magic to them... might be the start of EEVblog U...

[@veyselgokdemir]

I think it is good type to follow lessons and key ideas as real time.

[@LoLDistrictChannel]

great video... you explain it better than my teacher at college... thanks a lot...

[@call5sam]

Great video, It actually caused me to out my thirty year collage texts dealing with this issue. Pleas keep up the good work!

[@laser-sj]

dave this really needs its own channel...

[@bretthaupt1019]

I like this format about as much as the whiteboard. Little newer Whiteboard feel, which is a nice way to present things, and probably easier for you to use.

[@tag_of_frank]

MORE. Bring it all the way up to looking at a circuit diagram and comparing with the real life circuit

[@Eo_Tunun]

Looks like a good idea to me! You could call the new channel the EEVniversity? You are pretty good at teaching, many will benefit from such videos.

[@jac8696]

I like a cleaner interface like the one you get when using a dedicated digital pad like the Wacom. It allows you to write faster (and explain what you're writing) compared to a white/black board because you don't have to make the writing so large. I would be inclined to keep it on the same channel. Your channel is already huge, so I don't see any harm in keeping it that way. I would just add a category / playlist for these things. I like the idea of using bench footage as well with these tutorials, as seeing something in action helps make ideas / concepts more concrete. You can go from the Wacom introducing the subject, to the bench showing it in action.

[@Mrhollerr]

I just got introduced to bullion algebra last week so this video is going to be handy

[@therealjakeott]

This was fantastic. Thanks for the rundown!!

[@timmgiles]

eevlab is my immediate thought

[@vinicius.schmidt]

Waiting for your simplification tutorial! Thanks for class!

[@vinicius.schmidt]

kzbin.info/www/bejne/nnfZonicj8uAqqM

[@goose300183]

I like this, Dave. It reminds me of Khan Academy, which I think is a good lecture channel for various things. Suggestion for a continuation of this: Show us how the basic gates are physically implemented, for instance how these gates can be made with transistors etc.

[@louiskar]

Please, more of this! You should also do a series on basic electronics, talking about ohm's law, kirchoff's law, super nodes, super meshes etc. +1 for a darker background, it doesn't have to be black. This is really cool, thank you!

[@famossfla]

Dave you explained it so well I was anxiously waiting for the test :-) Great format with the tablet. I love it......

[@mattsadventureswithart5764]

More teaching, please. Here or another channel matters not, but education which is also entertaining is a good thing

[@larryg2320]

Love it! Very good refresher too. Might include a discussion about negative & positive logic and maybe why/when it's used. I saw a lot of neg logic in older digital military equipment. :-)

[@ralphf4416]

Dave's EEVBLOG DIGITAL LOGIC SCHOOL

[@ElectroMac74]

dave, drawingwise your 4 years old! no fences... good stuff, by the way

[@taekwondotime]

@26:00 It's commonplace to not write any symbol for the AND operation. (The dot is often omitted.) Therefore A and B would be written: AB. Also, it's commonplace to use an apostrophe (') to represent the NOT symbol as well. So "not A" would be written: A'.

[@megamonkey56]

this is fantastic!! i look forward to future episodes.

[@raindogred]

The old white board sticky note style must be a lot of work to produce, and don't appear near as much as I would like. If these can be produced relatively quickly on the tablet, then I'm all for it.. Having a special channel, great idea...the ability to go back and scan through all the lessons, would be handy. Be good if you could re-upload the older ones in this series from the original EEVblog..so there's a full resource of learning on the one channel??. Possible choice of channel name is either EEVlearn or EEVclassroom. Only caveat I would say is, if you get Doug in for special masterclass - keep it on the whiteboard.

[@daveturner5305]

Dave - For this type of content I like this approach and look forward to a series which builds to include flip-flops , counters etc. Of course by then you would have to be demonstrating propagation delay amongst other things. To do so effectively one needs logic analysers/scopes etc. so the screencast could not be the sole vehicle of presentation. Please more back-to-basics and then build on it; whether you create another channel or not is almost irrelevant. Just make sure that if you employ other presenters they maintain your style of presentation - it's addictive.

[@nickandpammorano9346]

I am a beginner and old. Invoice this format, Dave. Please stick with this format . Please start a new KZbin just for those of us who want this learning course. That way, we can still get your regular KZbin feed On this Chanel. Also, if you have a learning channel, all of those who do not want or need this type of learning channel, will not leave negative comments. Thanks again for your great teaching skills.

[@maxine_red]

I like the format a lot and the topic as well. I also like to see more here, but as I said on twitter, maybe once a week tutorial stuff will be better to not overwhelm people. Like continuing "Fundamental Friday" I would really look forward to a once-per-week thing.

[@TheRealSkyL1nELP]

Just wrote an exam about digital logics with different circuits and creating Grafcets for several circuits for Programmable Logic Controllers.

[@criptonessy3522]

Great video, I really look forward to more especially as the lessons advance. I'd be fine with keeping as one channel, but others may find these videos too different from the usual content, in that case I'd have no problem subscribing to a second channel.

[@thejews3094]

very cool stuff Dave! EEVacademy would be a great channel to sub to. I enjoy the Khan academy style. I'm learning the basics and navigating the volumes of videos on one channel can get confusing.

[@zer0b0t]

Maybe you can explain BCD and flip flops, then make a simple circuit with transistors and capacitors like the bistable flip flop.

[@zer0b0t]

It explains a bit how memory works, BTW I like the new format with the drawing tablet.

[@svampebob007]

yeah and adder and demonstrate that every logic can be done with NAND. I think more people should be interested in low level logic :) it really helps on conservative programing and also general programing where you don't want to rely on "what if" it works.

[@TheEricBooth]

I really like this format.

[@swe3tdave]

Feels like looking at a video from khan academy, i love it, will watch every single one of them!

[@thepain2222]

Major thumbs up! I like the format and I don't really mind if you leave you leave it on this channel but it could make it easier to find something specific if it went on another channel. Whatever you decide in the end, I'll be there.

[@osscar29]

Absolutely great idea you got here , I will be watching

[@jackevans2386]

Logic gate truth tables can be boring, until you find a use for them. An XOR gate is an extremely useful device for turning a single channel oscilloscope into 2 channels, for viewing the timing relationship between 2 digital signals. Either signal may end up inverted on the scope display of course, but the timing relationship between the 2 is clearly visible on screen.

[@jetraid]

Excelent idea, mixed with some actual circuit to show the result is the best way to teach

[@peep39]

Even if it is more work, I prefer your regular format videos. I like the idea of moving this to a second channel

[@jamesbuchanan3439]

I do like. I'd like to see you bring it all the way up to and past synchronous logic vs. asynchronous logic, which of course requires creation of bi-stable devices.

[@neuralnets]

Too Khan Academy for me, I like the Dave personal interactions and funny facial expressions and the rawness of the DaveCAD. Still great.

[@RandyLott]

Great video, Dave. I've been a long time viewer, since early 2010. I like this format and I think you should keep it on the main channel.

[@SkyCharger001]

for ease of use I would suggest using a tablet with builtin LCD. (that way you can fully rely on your regular drawing/writing skills)
