Paul gets coffee! Thank you!
Hey, much appreciated. I say this because I do maintenance for XPO and Holland freight and we do knock out where we remove c channel from concrete and jackhammer concrete and repour and weld dock plate and bumpers. A lot of work but definitely appreciated by those forklift drivers n truckers to keep production going. Good job n forgive me for grammar.

Isn't this the best educative channel we have on UA-cam??..
I have been retired for 3 years. I had to understand schematics and digital circuits as wells as pumps and motors for my job in power plant operations. I was not trained formally as an electrician. I knew what I didn't know but I could understand what I needed to know for personal and plant safety. However, I never understood enough that I could explain it or teach somebody else. I wish I was trained with these videos 30 years ago because they are so clear compared to drawing in a text books. May be then I could explained how things worked better because I knew things did work.
@@dwayne7356 great to hear your part of the story,I wish you well.On my part,I am an HVAC technician,I came to realise there is no way you can troubleshoot air conditioner units without understanding basic electronics & circuitry,......I swear this channel has a way of making these things seem easier than they do on textbook
Glad you think so
Quite possibly.
It definitely is the BEST EDUCATIVE channel here on youtube
I’ve said this time and time again, this channel is the most well thought out and informative on this whole platform. Schools should be showing your videos to engineering students. Incredible guys, can’t praise you enough.
Thank you, Don. Very kind
Listen my guy... I have looked far and wide.. just got started with Arduinos, esp8266, and raspberrypi.. I understand the mechanical side, the software side, but just couldn't find a well versed and exampled documentary on how circuitry works.. on how to calculate the resistance needed and everything all in one video... This is genuinely GOLD man. This makes sense. Thank you
See our new video on how to build mechanical versions of electronic circuits? Watch here: ua-cam.com/video/Zv9Q7ih48Uc/v-deo.html
You break the components/circuits down so clearly with simple images it makes it much easier to follow than most of the other subject videos on UA-cam. Thanks!
I can't tell you how grateful I am for making these videos; I have a hard time accepting "this does that" without an explanation of the underlying foundations of why it "does that". Your explanation down to physical properties of the material is precisely what makes me go "oh! that's why!" and what I've been looking for all this time I've been trying to learn electronics. Keep up the amazing work and thank you!
This has got to be one of my most favorite educational channels.
Absolutely top notch!
Wait what's this? A tech video with actual NARRATION and ILLUSTATIONS? Now THIS is how it SHOULD be done!
The only thing (not!) missing is loud drama music overpowering is voice.
Now if UA-cam only had spell check for the comments section Lol! 😄👍
You have taught me more in one Video that I have learned in my Electrical Engineering classes combined. Thank you.
Me too
In the video starting at 13 min 30 sec, the second resistor in the drawing shows 220 ohms, but you meant this to be 22 ohms.
Thanks it's noted in the video description
Check out NEW resistor video, everything covered! ➡️ ua-cam.com/video/DYcLFHgVCn0/v-deo.html
I just found this channel and I don’t know how I ever lived my life without it. Thank you so much for providing such fantastic content!
This is by far the most educative approach regarding optocouplers!
Thank you so much for Engineering Mindset
Today I wanted to know how optocouplers worked. Don’t actually need to but it intrigued me. I can safely say THIS is the best video explaining it. Thank you for the calculation of resistor values as well as the real life examples of being able to add them up.

@@EngineeringMindset Thank you! Really appreciate it.
You're the best teacher ever. I really appreciate what you did. Thank you !
The Optocoupler was my favorite device for keeping low/high voltage apart.Use to use it to drive Triac’s with it for light shows.Great video
This is truly the best UA-cam channel for the engineering minds.
Dude. You literally have the most informative channel on electronics. This has helped me a TON.
Your way of presentation is super
Thank you so much 🙂
First time I watched a clip from this channel I knew that I had to press subscribe
Best way to explain electronics
Glad I can trust youtube channel rather than my teachers .
This is the best explanation of a optocoupler I have seen... Thanks!
I can't thumb this video up enough times! Wonderfully explained!
A just can't fall asleep, if i dont watch one of this, it's just amazing...
I want to say keep the good work mate this channel deserve all the support 👌, I had recently a job switch to BMS and still find it quite hard to understand programs like Plain English(Continuum) or Function block(EBO,Vista) when doing troubleshooting, I appreciate if you could shed some light on this or somehow give an advice.Thanks again for all what you doing😊
Great movie! What a depth of delivery and at the same time how simple it is!
Great video and awesome job on making the content understandable.
Glad it was helpful!
This one so far most practical video on the channel 🎉 pls keep up this way! Thank you for creating useful content ‼️
Great video! Very instructive, definitely 10 out of 10 !
I love this video. Very clear and instructive. Animations of current moving makes it easy to follow. Thank you for posting !
I LOVE THIS TYPE OF CONTENT! Great work Paul!
Can you make a video on other types of optocouplers? it would be helpful too..
Vraiment super bien expliqué avec des exemples concrets et les formules mathématiques qui explique toutes
Here i am with my bachelor in Mechatronics having passed my electronics exam and getting a better explanation from this guy than from my professor
Let's hope your Prof doesn't recognise you 😂😂😂
Id have to say this channel has tons of good content, nice work !
Thanks millions for your videos.I am from the poorest of Country. no education lol. I love your mind .
Thanks a million times for your amazingly detailed and comprehensive video, it's highly appreciated
Very good presentation, easy to understand for people that are just learning
Very well explained clean and clear, I'd let my kids learn from this ( if I had kids) lol
Fantastic explanation and graphics. I always enjoy watching your videos!
This is the best educational videos ive seen yet very easy to follow and very informative.
This channel have everything about circuit 😂😂im so glad found it as before start my first year in university as electronic engineer student
It's 1am and I can't stop watching these videos. My mind in blown on how our world in built on what's basically Legos. I need to go to bed in order for work tomorrow!!!
One of my favorite channels on UA-cam. Could you please do a video on compressed air drying techniques, in particular HEAT OF COMPRESSION DESICCANT DRYERS. I’ve worked in oil and gas, pulp and paper, and defense and have had these in every industry but only recently had problems with them. Thank you.
When discussing optocouplers, it's a good idea to mention Vactrols aka resistive optoisolators. They aren't ofren used these days in new designs, but in the past they were widely used in audio gear like guitar effects and analog synthesizers. Since these are both popular topics, DIYers are likely to encounter the Vactrol sooner or later.
Your big talent I think is that you have a unique manner to make all the electronics to look like so simple!
You are a blessing for students. Thank you so very much.
I am so happy I can show this video to my kids. Thanks again.
Very nice and easy to follow demo as far as the basic functioning. Thanks Sir so much.
Clearly understands ur explanation. Thank u sir!
Great job sir .. I really admire your effort to explain the things in such a simpler manner .....
As a comp sci person, always struggled with these switches, very basic theory as you explained.
This was actually better than I thought it was going to be.
Thank you for explain with the animated circuit. 👍👍🌹🌹🌹🌹💝
Fantastic work !
Keep it up.
👏🏽👏🏽👏🏽👏🏽
Educational videos .I shared with all my friends . Salute to your hardwork.
Best chanel educating not only theory but practical too by visual animation. Fantastic explanation of circuit 👍👍👍
Thank you sir for the info about optocouplers🙏🏻👍
About 4:30 is where it starts to talk about the physics, good stuff!
I have learned som much from this channel, thank you thank you
Thought the title was "How octopuses work", which is why I clicked. Can't say I was disappointed.
Came for the octopuses, stayed for the electronics.
Octopuses for HH tier stuff
There's a slight mistake at around 13:20 where you put 220 ohms instead of 22 ohms. Overall, I like your video a lot!
I was like huh? 👍
The mistake must be intentional just to see if you are paying attention in this class. If you can instantly spot the mistake, then you are well on your way to becoming an electrical engineer!
Amazing, as usual.
It's so satisfying watching the video. 😍
Very easy to understand, the graphics are simple and to the point.
I worked in a nuke plant for a while. We were not allowed to take flash pictures behind the control panels (to verify wiring prints) because the flash could (and did, apparently) trip some opto-isolated components!
Oops...😉
عرض ممتاز وسهل ومبسط نشكر القائمين على البرنامج. ونتمنى ترجمة المقاطع إلى اللغة العربية.
Fantastic electron demo. Doesnt get much easier than that, and its not easy at all
Very interesting. Thanks for sharing and teaching us.cheers from Algeria.keep going please.

Fantastic and wonderful and beautiful and amazing and superb and brilliant explanation....thank u
I've learned more watching the first half of this video than I'm comfortable to admit.
Awesome video. You make it seem like a walk in the park. Should I have come across your content during my school days I was going to ACE most modules.
Exceeded video. Thank you. 👍
At the beginning, around 1min, the PC817 is showed with the pins 3 and 4 in inverted position. It would be ok in schematic presentation.
Sir,good explain. Thanks
