How To Read Schematics 3. Learn How To Understand Circuit Diagrams

[@LearnElectronicsRepair]

*I now have plenty of schematics to use for a part four - you can keep sending them in but they may not be included. Unless viewers like the idea and it continues. Thanks to everyone who emailed them to me* 🙂

[@napoleon760]

Just coming across this. Gone through the 3 videos...where is the fourth?

[@H3yoiu]

Thank you very much! For all your videos. Have been interested in electronics since my school days, and the passion to learn about the subject had increased over the years. I discovered your channel almost a year ago, and love your way of explaining the stuff in detail. Thanks again for spending your valuable time in making these videos...always looking forward to them. Is it possible to do a video of an brother printer L3550cdw power supply, the printer does not power ON. So far, I have been unsuccessful in finding the schematics for it. Thanks

[@castlecodersltd]

This mini-series has been great, thank you for it. It would be good if you would do a video on identifying, on actual schematics, the basic building blocks (start up circuits, the current sense, voltage dividers, etc) because sometimes, in complex diagrams, it can be harder to identify them ☺

[@JaimiEvans-qc1ji]

Thank you for showing us how to read schematics and showing just how you really need to know how the components work before you can even start to read a schematics. This is making me go back to your all you need to know about components videos . Thanks again look forward to more videos

[@billguitarvin]

Richard, thank you so much for this video series on reading schematics as well as all the numerous other videos you have made! I have learned so much, thanks to you. I too would love to see some videos on typical building blocks that are found in circuits. Thanks again and take care.

[@rhearowland8362]

Could you do a more in depth video about the basic building blocka of schematics? What you've shown in the 3 videos is really helpful in learning and understanding, a more in depth one for the building blocks would definitely help tho❤

[@Dutch-linux]

I know how to read schematics... but you explain it very well once you know what things mean on schematics it is easy to read them another great video

[@Dutch_off_grid_homesteading]

Heya, 46:43 I would love to see more bilding blocks to unterstand more schematics. 51:10 dc to dc converter look it up on google wel the most explanations by differant people I don't unterstand but the way you explain it I unterstand right away so I would be happier if you explain it ( in a new video ( I could even pay you for it, I mean you put time in it to make those video's))

[@mickduprez9598]

+1 for building blocks, I understand how the components work by themselves but how he explains what each component is doing in a particular 'block' is very very helpful, cheers.

[@jonsumisu9016]

Your videos are the best. I was lost when looking at schematics, but following your advice and trying to understand the flow of the signal, and then just concentrating on that part of the schematic, I get a much clearer view of which components might be causing the problem. Thank you so much.

[@guymunson4863]

This is gold, thankyou

[@DrTonyS-eq5xs]

Excellent video look forward to your next one with example schematics from your viewers

[@tomaskorenek1259]

great helpful video, please do more of these how to read schematics videos, sometimes i do work on old amps and despite having schematics i struggle to locate the fault - especially if its something uncommon. I do aprecciatte your effort to teach us the stuff - thank you

[@andyantoniou7667]

one of the best schematic videos, very well demonstrated and easy to follow

[@paulhyland4653]

Yet again ann awesome video thanks

[@andymouse]

Looking forward to part 4 ....cheers.

[@florinb114]

very good, thx

[@itsallgoodman8867]

good stuff, thank you

[@SimonSlothindianer]

Watched all three parts and learned A LOT! Thank you very much.

[@Lightrunner.]

Great Video.🍻💯👍 Thx Richard . Ähm, question. Where are the cobolds who transport the electrons 🤔🥳🤪🤪🤪🤪🤪🤪 Vodoo😂

[@nelsoningalsbe8262]

Richard after watch all 3 videos 3 times each I think I have some parts of what your teaching being ham for mor than 30 year I'm learning more from your teaching about my hobby i love so much I will say with all my heart thank you so much 73 n4jrs

[@marauderofdeath6401]

Another great video in a great series!

[@mareksettle]

Thank you for your time and dedication to these videos. Your knowledge is priceless, and your personality makes it fun.

[@JayJay-wv1vx]

Where is part 4 of this series? Pl update the discription of this video and post link of part 4 in this discription. Thank you.

[@davestake44]

Another great video thank you.

[@JohnVullo]

Thanks a lot! I bought an incredibly rare MIDI controller called a "Synthaxe" last year. It has two small problems with it and I've been trying to figure out how it works to repair it and keep it going for as long as possible. These vids are def helping me get a better understanding whats going on.

[@666gelinas1]

Great video! Looking forward to #4

[@davidshertzer900]

This is a great video series- thank you for sharing your knowledge.

[@user-zn6oc2vs8i]

Stupendous channel my friend!

[@MarkHunterLionstar]

Great Refresher for me! Thanks!

[@kriswillems5661]

The main difference between processors and microcontrollers is not internal RAM or ROM, but the presence of hardware timers, PWM modules, AD and DA converters, programmable and often multi-functional or bidirectional GPIO pins and other hardware modules that are meant for controlling other external hardware. The first microcontrollers almost never had internal RAM or ROM (nowadays ROM and RAM tends to be integrated).

[@Prash1c]

Thank you for part 3! :)

[@justmc62]

Thanks again Richard for your fantastic tutorials... I think I've watched just about all of them 😊... Would really like to get to know the application and operation of " op amp '" devices better. Unless I can't find it , I don't see any of your basic "How to Fix Stuff " tutorials explaining them... Would that be something that could be persued in a future video? Or point me in the direction of where it would be... TY

[@LearnElectronicsRepair]

I will be doing 'all you need' about op-amps soon

[@andymouse]

I am glad you finished off the 'O' in ' μ Cont ' (31:10) as I was mildly offended !......cheers Lol !

[@Dutch_off_grid_homesteading]

Heya, oke I have some schematics so that's gone be fun part 4 your spoiling us nice

[@sivoltage]

is there a part 4?

[@Foobar_The_Fat_Penguin]

I read that transistors are designated with Q because the old TO18 packages look like the letter Q. And it was written on the internet, so it must be true.

[@nabman_]

Q is for quiesence.

[@gerardpierre9756]

Very informative

[@damdam9625]

excellent

[@jonsumisu9016]

Why are things changed when the old way was better? The old way of showing tracks crossing made more sense, and was much clearer.

[@darkdepth1991]

Still onboard for part 3 :)

[@kironsk7697]

A audio amplifier's fuse which is situated on the output of a bridge rectifier getting burn out once the power is turned on. please tell what are the possible reason of it? And input voltage of bridge rectifier is 26v ac and I found 36v. DC on the output of bridge rectifier so is there problem with this bridge rectifier?

[@fisforfriendship6093]

So microcontrol controls few wpecific things and processors control multiple signals

[@gbondbasic]

yes more please

[@Dutch_off_grid_homesteading]

Bedankt

[@simplefaithforall3174]

"Q point = Quiescent point, resting point. When the amplifier circuit is left undisturbed, Q point is all quiet." When a signal is applied the circuit become active of course and is now non-quiet!

He sounds like present-day McCartney in an interview.

[@Synthematix]

Stoke on trent?

[@garypoplin4599]

1:09 - Too bad you can’t make your mouse cursor bigger, also. I can hardly see it unless you move it slowly.

[@LearnElectronicsRepair]

Yeah it has been mentioned and I fixed this on later videos

[@garypoplin4599]

@@LearnElectronicsRepair Thanks for all you do. I’ve learned more electronics from you than I ever did in engineering school!

[@user-xg6rn6ym5o]

Video's good but doesn't really get to the point spends way to much time trailing off
