Dave ... I just retired from the industry a year ago after 52 years. I've been watching your video blogs for months and must say that you do the very best job explaining concepts in a very entertaining manner than any other I've found. GREAT JOB !! I have seen in the comments trolls troubleshooting your videos. Don't let them bother you. You have something really good going on here.
As a very “young player,” it’s great to hear that kind of endorsement from a seasoned pro.
Well, that made me feel old - in college days, before they stopped students from sneaking into the faculty dining room, I sat at the table next to Clarence Zener. Woo Hoo - brush with greatness!
Brush with brush with statistics fame: my doctoral advisor took a stats course from Rensis Likert, inventor of the now ubiquitous Likert Scale.
I'm just a hobbyist, but I have deep love for electronics. Videos like these also keep us amateur students interested in the subject.
Thank you for taking the time to make it. I loved it. I'm going to binge watch all the fundamental videos in the series!
I like these sort of videos the most Dave. Very educational. More of this would be great.
Exactly!
200% agree. these are my favorite type of videos too...
I fully agree. This is why I subscribe to EEVBlog. I never bother watching mailbags or teardown videos.
I totally agree!
+rovku and many others don't bother watching tutorials and only watch the mailbag and teardowns. They have an equally valid opinion. In fact data seems to show that they outnumber the tutorial people.
Working 35 years in the professional electronics industry and i never considered the iconic shape of the zener symbol. We are never too old to learn something new! Thanks Dave :)
Fundamental Fridays has to be the best segment on the EEVBLOG.
thanks dave
You are fifty times better than my instructor, Dave. You should record these kind of videos more often. Thank you.
Yes
Who needs a degree when you have Dave!
I am literally gonna say in a job interview that I watched a lot of eevblog
If they don't know him then they suck
i wish i had watched these videos in school. i'm working now and these are great for building the intuition i should have built as an EE graduate (instead of getting bogged down with math).... i'm learning way more here than i did in my 2 semesters of analog electronics courses.
Amen!
Still good to go to school to get graders you dont even need
@@Rainbow__cookie
You need the grades/knowledge to perform better at work.
Fundamentals Friday!!!
YES!!!
MY FAVORITE!
Cannot tell you how much i love your teaching videos. Again awesome !!!!! Thank you so much.
knew most of this already but still learned something interesting. Thank you! Your videos are always worth watching. Much appreciated!
Dave, Very nicely done. I have learned a lot and appreciate how well you put the concepts and related functional specifications into perspective. Keep up the excellent work! Thanks, Bob
Great design teardown, good references to the data sheet with explanations,practical use of hardware,basic circuit calculations with various loads and input supply .All in all, this video sets the standard.
Man I wish I could hang out with you for a week. This stuff comes so naturally to you. I am learning so much and I have been working with electronics for 20 years.
what a great presentation Dave I look forward to seeing more of your foundation series videos.
Thanks Dave, I always appreciate the fundamentals videos. They might never bring in the number of views that the mailbag or teardown videos do but they will be on RUclips for many many years to come (hopefully), helping out future newbies and also rusty oldies like me that need reminding.
looked at tons of videos for zener diodes this was the best one. thanks
I think I struck gold. This is one of the best videos I've seen explaining Zener diodes. Thank you!
Incredible straightforward explanation! Thanks, Dave!
I love this guy. I suggest the videos made by him to anyone that wants to learn about circuits.
great video Dave. takes me back a few years when I studied electronics. have long forgotten some of these principles.
I'm so happy your channel is in my life. helping lots in my mechatronics class
Mr.Dave, you are so great man. You deserve a lot. thanks is not enough for you. I learned a lot from you. I wish all professors would be like you. This will change the future of education. On no account, do not stop making videos, please. Big thanks from Egypt.
Even though I'm quite familiar with this topic I found this to be quite interesting. Let's hear more of this kind of stuff on the EEVBlog! Tear downs only go so far...
Always love the fundamental video, partly because it is recognition what you know (of course gratifying 🤓) and picking up additional information! Can't go far and deep enough.
You've covered the essentials very well, Dave! It doesn't hurt to refresh my memory from way back at Community College.
Great job! In Poland in my university, professor recommend your videos - so it is the best proof that there videos are immensely educational. Thank you.
Very good and detail explanation on Zener. Got clarity on some of my question I had in real-world application.
I know this is an old Vid Dave, but your channel is invaluable. I've been binge watching for days now, and really cleaning up on the theory I missed out on in college some 20 plus years ago.
I tried watching other RUclips videos but they confused me even more but your sir really helpful I'm really glad I found your channel
Fundamentals Friday is my favorite episodes. I have no idea if they are popular, but over time, these will be the most important episodes you do.
You are a very good teacher. Funny at the right times, light but full of info that's easy to digest, and you have a pleasant voice.
I think the way things are taught, especially how they are said, plays a big role in students being capable of absorbing the concepts.
Thank you Dave, I have to say your videos are very helpful and informative. With the knowledge of EMC testing, I have always dreamt of working as in EMC design but at least with your videos I am extensively increasing my knowledge on the basics. Who knows something might Knock the door and will remember you for sure. Thank you again!
Excellent instructor and Zener diode lesson. Thank you for teaching.
From a beginner, thank you very much, that answered my questions perfectly on using a zener diode as clamping protection.
Very nice. Best video about zener diode seen so far. Comprehensive enough to get the idea and simple enough not to lose interest/attention till the end of the video.
I'm in love with you Fundamental Friday videos, please keep up the awesome work
Great video, many thanks Dave !
A Very good video! No worries about extra length - the longer it takes, the deeper you can dig.
Man congrats. I was googling in order to understand but without lack. The real secret of zener diode is actually its dynamic resistant that explains exactly how it regulates the voltage. Thanks so much for educating us.
I wanted to thank you especially for the videos like this. The amount of knowledge you share is vast, but the way you share it is the greatest part about it. Thank you for sharing your time with us and teaching with clarity, vigor, and enthusiasm. Cheers!
Vigor and enthusiasm indeed! Much appreciation Dave.
Thank you!! I was aware of the basic properties of the Zener diode, and didn't understand why people avoided them as a solution for voltage regulation, and your tutorial helped me to understand why.
I really like your channel , and finally its Fundamental Friday , i was missing this part on your channel .
Dave, love your videos and clear explanation! Keep up the great work!
Finally, I understand what the Zener is for :D thanks a lot, Dave!
Love your tutorials. keep up the good work and get well soon.
Thank you for making these long form videos reviewing electrical components in depth. I've been out of practice for a while... I graduated college 9 years ago and have been working in other industries. I was in dire need of fundamentals review.
I just absolutely nailed a HUGE interview thanks in large part to your channel (specifically op-amp and transistor circuit analysis). Your energy and presentation made these topics very fun to watch and easy to follow along with. Lets see if i get this job... :)
Thank you so much for sharing this kind of knowledge. It was so hard to choose between engineering and human services in college!
Thanks! I haven't looked at this stuff since college, and I still learned something I remember having trouble with.
Love your work Dave. I’m currently studying an AD in electrical and electronics engineering and your videos are much easier to understand than any of the material provided by the university.
Your teaching style with smiling face is awesome. Thank you so much Sir.
Awesome video and a very interesting and useful topic. Love fundamentals videos. Demonstrates the potential of some people to explain what others can’t in the classroom. If you have the video about how to calculate the Rz and Zener, it would be great to put link in the description.
Awesome. Wanted to mention that I'm missing the times when you did EE lecture kind of videos. Enjoyed all of them.
I learn so much from your vids Dave, please do more of this sort of basic theory and common application stuff..
Nice explanation! Looking forward to the video about clamping and protection devices.
great discussions about zener diode . thanks for sharing your idea sir.
Thank you for the information on the component symbol. It is interesting that component symbols are based on a characteristic of the component. This makes complete sense, but I find it fascinating when I discover why the symbol is used. Great video
Your videos and tutorials are excellent. Please keep it up good work!
Interesting. Now I know why my DIY EPROM programmer wasnt working (very tight voltage requirements and I was using zeners with no knowlege of the internal resistance etc).
These videos are absolute gold dust. Thankyou for taking the time to make them.
I love fundamentals Friday and teardowns! I NEED MORE!!!!
Videos about electronic parts are very useful!. Thanks. It is also good to say where they are used.
I love these kind of videos!! Thanks for making another one!
Really comprehensive and easy to understand. Thanks for making this Videos.
Thank you for posting this explanation! ❤❤ Studying for my test and you explain so clearly! 😊
thanks Dave learn something every time from these and the older tear down videos.
Dave, any chance you could talk about more circuit protection stuff? MOVs, spark gaps, etc. and *when* each of them should be used?
Yeah, that's on the cards.
good. because abstinence-only education doesn't work with electronics hobbyists.
I would also cover speed, repetitiveness and energy surge ability of all those components - which to use in specific conditions and how to design a reasonably good protection circuit. If we are talking about protection...what about poly-switches.....
What does Dave mean by its on the cards
He is thinking about making vid about it...
These are your most useful videos
First and foremost, I'm happy to see you're healing quick and well, Dave! :)
I just love this kind of videos. I appreciate you taking the time to share your knowledge with us! :)
As a beginner in electronics, I'm fascinated with how microcontrollers work. Are you planning on making a video about this subject in the future? Just a suggestion. I'm sure other viewers will find it interesting and useful as well.
Thanks once more! :)
Yes yes yes. I already knew most of zeners but I love your basics videos! Do more of em!
Thanks for you video. Helped me with my Ham Radio studies.
Great explanation! Thanks, Dave!
Yes, love the fundamental fridays !
Excellent! Keep it up with the series!
Awesome! I like fundamental Friday! Thanks for the video Dave!
Dave,
Thanks for the refresher!
Rob
Good job Dave. Enjoyed it and learned quite a bit! Thanks.
Thanks Dave. Another very nice video
Lots of good information. Thanks Dave!
Short and simply done, nice lecture.
Such a simple and easy to understand explanation. Thank you.
This is my favorite segment!
U R absolutely the Best teacher in this World
The more you know....
Awesome video Dave!
Waiting for more of this kind :D
I do not know if you will ever read this, but i want you to know that your videos helped me a great deal through my exams and I can't express how gratefull I am. I am 27 yold from Greece studying for my 2nd Class Marine Enginneering Certificate after a long time away from the profession due to health problems and I've been through a lot lately. So many setbacks i can't even begin with. Your videos where helpfull and cheered me up while in a really bad place. As a mechanical engineer my electronics knowledge was limited to the stuff i learned at school and it has been a very long time in marine engine rooms's noise and heat since the last time i studied about electronics, so your style of explaining helped me fill many of my knowledge gaps in and pass my exams. I will never forget your help. I will also try to donate a little something as I am in a realy bad place right now... I wish i could do more. May you always have good health and keep up the good job. I wish you the best with the new lab .You have my everlasting gratitude and respect.
Thank you Dave!! Awesome video as always!! Very educational
very helpful. i was confused to understand the diode as normal voltage regulator but as you cleared things up that it isn't a good device when load is connected.
Excellent video. I like that he makes the occasional mistake and corrects it. Very real-life.
Thank you very much, Sir! That was VERY helpful!
You have to respect a guy who’s so enthusiastic about explaining things.
Thanks, in particular I found the dynamic resistance part rather handy, cheers
Great video Dave!
Thank you Dave, great video!
Great video!! I love these component videos!
Very nice, very easy to understand. Thank you, more of these would be awesome!
Awesome video! I always love fundamentals fridays.
My instructors in college (40 years ago) may have been good engineers but were poor teachers. Dave here surely is good at being both. Liked and subbed!
Especially after the comment at 10:48 I'm convinced that your inspiration for talking about zeners right now is the KNEE curve. :)
Love these fundamentals friday videos. thanks
