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.
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
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
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.
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!
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!
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.
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!!!
Wish I could join but can't afford right now but I'll tell you what this video is ridiculously awesome. I don't have much knowledge in this area but I do electrical and am easily intrigued by how things work. This is the way God has made me and it's exciting to be moved by science.
Oh my Gosh you are gunious 1st time I understand because of your gunious presentation thank you so much sir. I listened other video again & again but I didn't understand . but I understand your presentation so far thank you so much may God bless you sir you are gunious.
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!
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.
I still remember back in 1980. We had an industrial application to measure PH Levels. It had an optocoupler of earliest design. A 1/2" plastic tube with 2 wires coming out of each end . // \\ They lasted about 4 months, and had to be replaced at a 1980 price of $80/EACH. 🤓 Much at my bosses dismay (wasting company time), I found out that there was a photo-transistor on one side, and a PR-2 flashlight bulb on the other side. The bulb burned out every 4 months. 🙄 These were glued in place with silicone. Bulb was less that a dollar.🤐 Boss never accused me of wasting time again.😄😄
There were many very high quality optocouplers available in 1980 with extensive reliability data and used for the most sensitive and critical military and space apllications as well as commercial applications so you must have come across some really kludgy design.
Hi I appreciate your effort creating the video. I noticed around 1:44 that the load is connected to emitter. Usually the load is driven by the collector.
Very complete and concise presentation. I noticed one thing about PC817 though that surprised me. You show the pins 1, pin 2 on one side and pin 3, pin 4 on the other. According to the Sharp datasheet, pin 3 should be pin 4 and pin 4 should be pin 3. That is, the pins are numbered down one side and up the opposite side, not both sides from top down. Not sure that will cause anyone too much heart burn, but ...
Providing Complete knowledge about something is just great. You are the best. I don't get doubts while watching. Soo well explained. Thank you for your work. :)
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.
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!
I like your video´s. at 3:25 and onwards, you show two batteries. current in one battery flows into plus pole. on the other battery it flows into minus pole. Notice that i'm not referring to electron flow versus traditional current flow.
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😊

Glad you think so
Quite possibly.
It definitely is the BEST EDUCATIVE channel here on youtube

You have taught me more in one Video that I have learned in my Electrical Engineering classes combined. Thank you.
Me too
This is truly the best UA-cam channel for the engineering minds.

@@EngineeringMindset Thank you! Really appreciate it.
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
You're the best teacher ever. I really appreciate what you did. Thank you !
This is THE most interesting video i've found on this subject so far! Really well explained 😍
Thank you!
Glad it was helpful! Thank you
Best way to explain electronics
Glad I can trust youtube channel rather than my teachers .
Dude. You literally have the most informative channel on electronics. This has helped me a TON.
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

Your way of presentation is super
Thank you so much 🙂
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! 😄👍
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 one so far most practical video on the channel 🎉 pls keep up this way! Thank you for creating useful content ‼️
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
I've learned more watching the first half of this video than I'm comfortable to admit.
Great video and awesome job on making the content understandable.
Glad it was helpful!
This was actually better than I thought it was going to be.
Your big talent I think is that you have a unique manner to make all the electronics to look like so simple!
This is the best explanation of a optocoupler I have seen... Thanks!
Very well explained clean and clear, I'd let my kids learn from this ( if I had kids) lol
Thanks millions for your videos.I am from the poorest of Country. no education lol. I love your mind .
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!!!
This channel have everything about circuit 😂😂im so glad found it as before start my first year in university as electronic engineer student
A just can't fall asleep, if i dont watch one of this, it's just amazing...
I can't thumb this video up enough times! Wonderfully explained!
This is the best educational videos ive seen yet very easy to follow and very informative.
I am so happy I can show this video to my kids. Thanks again.
As a comp sci person, always struggled with these switches, very basic theory as you explained.
عرض ممتاز وسهل ومبسط نشكر القائمين على البرنامج. ونتمنى ترجمة المقاطع إلى اللغة العربية.
Very easy to understand, the graphics are simple and to the point.

About 4:30 is where it starts to talk about the physics, good stuff!
[13:10] the diagram shows 2 resistors with 270ohm and 220ohm instead of 270ohm and 22 ohm.
Very good and informational Video!
literally just seen that and checked comments for anyone else that noticed lol

Thanks a million times for your amazingly detailed and comprehensive video, it's highly appreciated
Keep up the good work Paul, I love how you can dumb these circuits so I can understand easily
It's so satisfying watching the video. 😍
You are so gunious some staff 1st time I understand because of your so gunious exponation you are truly angel thank you sir. 🙏😀.
I have learned som much from this channel, thank you thank you
Oh my Gosh you are gunious 1st time I understand because of your gunious presentation thank you so much sir. I listened other video again & again but I didn't understand . but I understand your presentation so far thank you so much may God bless you sir you are gunious.
Very good presentation, easy to understand for people that are just learning
Best chanel educating not only theory but practical too by visual animation. Fantastic explanation of circuit 👍👍👍
Beautiful world of electronics, physics laws and maths. Thank you for very informative video
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 😂😂😂
My First time on this channel. Fallen in love with it
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!
Fantastic electron demo. Doesnt get much easier than that, and its not easy at all
Thank you for explain with the animated circuit. 👍👍🌹🌹🌹🌹💝
I love this video. Very clear and instructive. Animations of current moving makes it easy to follow. Thank you for posting !
Vraiment super bien expliqué avec des exemples concrets et les formules mathématiques qui explique toutes
Thanks!
Thank you Cesar, much appreciated
Great movie! What a depth of delivery and at the same time how simple it is!

Great video! Very instructive, definitely 10 out of 10 !
Very interesting. Thanks for sharing and teaching us.cheers from Algeria.keep going please.
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.
Id have to say this channel has tons of good content, nice work !
❤️❤️❤️ I loVe ELECTRONICS BY your explanation..
Iam really fan of your video ☺️☺️ and ur animation is well good
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.

This is really interesting. Thanks for explaining this stuff to us viewers.👍
Hi I appreciate your effort creating the video. I noticed around 1:44 that the load is connected to emitter. Usually the load is driven by the collector.
Simply demonstrated optocoupler circuit,thank 's for you sharing and added knowledge,,sincerealy your's
You are a blessing for students. Thank you so very much.
13:38 Position H-20 looks like it’s seen some action 😉
Nice information will reach even beginners 🎉
Very nice and easy to follow demo as far as the basic functioning. Thanks Sir so much.
Very nice explanation. It's like in a classroom.
This is explained so well. Thank you sir.
I LOVE THIS TYPE OF CONTENT! Great work Paul!
Can you make a video on other types of optocouplers? it would be helpful too..
Very complete and concise presentation.

Clearly understands ur explanation. Thank u sir!
Back when I started in electronics a opto coupler was a diode and photo transistor wrapped in heat shrink
I like this video , very complete ...
Nice👍
Fantastic you tube channel. very thanks
Another excellent video with great explanation. Thank you.
Providing Complete knowledge about something is just great. You are the best. I don't get doubts while watching. Soo well explained. Thank you for your work. :)

Love your videos and your videos are the BEST
I enjoyed learning due to this video🤟
Good video but in Feedback circuits optocoupler are much more interesting in the way they work.
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...😉
i really love this channel
Hi brother super your all the explanation you said was very clear Thank you brother👍👍👍🙏🙏🙏
Educational videos .I shared with all my friends . Salute to your hardwork.
I rarely subscribe to channels but I did this time
