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.

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

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 KZread. 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!
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.

You're the best teacher ever. I really appreciate what you did. Thank you !
This is by far the most educative approach regarding optocouplers! Thank you so much for Engineering Mindset
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!
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😊

This is truly the best KZread channel for the engineering minds.
Id have to say this channel has tons of good content, nice work !
I love this video. Very clear and instructive. Animations of current moving makes it easy to follow. Thank you for posting !
Great video! Very instructive, definitely 10 out of 10 !
I can't thumb this video up enough times! Wonderfully explained!

One of my favorite channels on KZread. 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.
This is the best educational videos ive seen yet very easy to follow and very informative.
I LOVE THIS TYPE OF CONTENT! Great work Paul! Can you make a video on other types of optocouplers? it would be helpful too..
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!
Thanks a million times for your amazingly detailed and comprehensive video, it's highly appreciated
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!

About 4:30 is where it starts to talk about the physics, good stuff!

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.
Nicely explained. Suggestion for BOM consolidation: 390 ohms would do just fine for every resistor in the demonstration circuits. No need to stack multiple resistors of various values in series for something as simple as an optocoupler, whether it's an integrated package or a homemade Vactrol.

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.
Simply demonstrated optocoupler circuit,thank 's for you sharing and added knowledge,,sincerealy your's

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.
I have learned som much from this channel, thank you thank you
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 ...
Clever use of the photoelectric effect.
Fantastic explanation thanks a million.
Beautiful world of electronics, physics laws and maths. Thank you for very informative video
This is really interesting. Thanks for explaining this stuff to us viewers.👍
wow, this is some quality video creation
You are so gunious some staff 1st time I understand because of your so gunious exponation you are truly angel thank you sir. 🙏😀.

My First time on this channel. Fallen in love with it
Great illustrations.
Great Explanation!!!
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!

You can also use them to isolate analog signals from their sources. Generally, negative feedback is needed to keep the bias at the optimum level and the gain predictable.
It's so satisfying watching the video. 😍
This is an enlightening and very educative video. I would like watch more of this. But i have a question for you for this particular video and this is: why haven't you added the current rating on the diode in the calculation?
Love your videos and your videos are the BEST
I've learned more watching the first half of this video than I'm comfortable to admit.

Hi brother super your all the explanation you said was very clear Thank you brother👍👍👍🙏🙏🙏
Simply great teaching, thanks for sharing your knowledge!! May I please ask you about a "conclusion" I have arrived to, via your videos? In your video about BJT does it look like you can adjust the "door" how much it is open, by adjusting the current, or in a way make it act as a resistor. And in this video do you show that one side is an LED and the other side a light-activated BJT. My question is since a LDR is very unliniar if it's possible to use the BJT optocoupler as a variable resistor?
