I've watched 25 of these tutorials and this is the 1st one that actually helped me build my very 1st circuit!!!

Your English is very good. Your videos are very, Very nice and informative. Presentation excellent. It is so nice to watch video without annoying music being played. It is so nice to hear you speak while instructions are being shown and explained very clearly. You have the best videos for electronics projects on KZfaq. YOU ARE A VERY, VERY GOOD TEACHER THANK YOU

You had me at, "enough talking, let's make something" finally a tutorial that's shows how to do this without the extra info. The videos for these types of circuits are ubiquitous on KZfaq. I know some folks need that extra info, but I am only interested in how it is put together. I am not smart enough to understand exactly how it works. Subscribed

My stupid head is hard to understand electronics and circuits but when you lay it out like this it is much easier !! Thank you Mr Cro Man. Subscribed

I do like these "open framework" circuits of yours - very much a literal circuit diagram

your English is clear and easy to understand, Your explanation and visuals are very informative. thank you!

I just found this video and found it quite fun to see this skeletal method of circuit building. I had used the 317 to create a self regulating heater circuit for my 1950s model train. I added a thermistor as the R2 and a fixed reference resistor for R1. There is a heater coil on the output and it is used to vaporize an oil in the smoke housing. I also have a small DC Can motor and fan to blow a puff of air through the housing in synch with a Chuff Sound board. If the Heater gets too hot it can burn out or use up all the oil in the housing. If it gets to cold the oil stops evaporating. Other variables i had to deal with is the Track Power that runs the motor in the engine starts at 5 volts and goes up to 17 Volts. I isolate the 317 from that variance in track power by 1st converting the AC to DC then running it into a Buck Boost Board set to 9 Volts. I find that with the heater I used 8 to 12 Ohms will heat up to 150C with 9 volts. The other variable I had to accommodate was the fan to make smoke flow out. It will cool the heater down as it pushes out the smoke. When all put together the heater will start up at 9 volts as the thermistor is very high resistance as room temp 25C. As the thermistor sees the Temp approaching 120C it will start to reduce ohms and being R2 it lowers the output power. Then as we turn up the track power the fan moves air faster so the thermistor will cool and Ohms will increase which raises the energy sent to the heater. If i have all the parts correctly balanced and the right R1 value the system balances between 120C and 130C quite nicely. This provide a nice puff of smoke at low speed leaving the station, then once on the main line and speeds increase the smoke maintains a nice plume out the stack as the engine speeds along. Then as we slow down the Thermistor will begin to heat up with less air flow and that will lower the energy coming to the heater. It all works really nice. We used to have good smoke at low speed then none at high speed or burn up in low speed and have smoke at high speed. It was a battle to have fun smoke at all speeds. this 317 is so simple and easy to configure we even have a circuit board made and we can sell the assembly to other Train Hobbyist. And it is all very affordable for them. I appreciate you continue to teach today and applaud your efforts. I try to share with other train folks but these older trains are left with older guys now so it is harder to bring young ones along. We are using 3D Printing to make spare parts and new engines. We hope to bring new Hobbyist into our model train because it is a very good scale. 1/64 scale which is larger than HO but smaller the O (Lionel). I am trying to use science and technology to help keep it alive. We are now finishing our Sound System with ESP8266 Microcomputer. I am at 73 learning C++ AGAIN! But with Arduino and these new boards it is all part of the IOT and STEM like studies which i find online like this lecture and demo you made for us to learn from. I wish you very well and hope you get many more viewers. Thank You for a great video, Dennis in Virginia USA

I did enjoy your video- relaxed, entertaining and informative ! Thanks !

Perfectly illustrated and explained. New sub

This was interesting and thank you for the great camera work it’s easy too see what you are doing. 👏🙏

Thanks for doing this tutorial. It is simple to follow and not complicated. Very informative.

Your videos are the best! I plan to breadboard at first then I will solder the the circuit together.

Excellent video thank you. Your second language is fine. 😁

Best and uncomplicated circuit presentation I have come across. Thanks for sharing.

Plain and simple project with explination makes it very interesting aswell as likable.

Hi , I like the design of yours , good this project to regulate the fan motor on Fume exhaust that I has building. Thank you 🤗

Very Good Video, Not Boring ! Thanks For Your Time & Effort 👍🏼

I enjoyed your video and how humble and kind you are expressing how much fun building these simple circuits and speaking English considering it is not your native language. However, I understood every word you said. Congratulations for all. I will subscribe, and like.

I really liked! Thanks from America!

Your English is clear and great, the content is superb

I've made this circuit many times over the years. Be sure to mention the amp rating for that op amp is 1 amp per manufacturer specs.

Best tutorial of LM317 regulator!!!

My students never listened :) Thanks for sharing.

As seen by other viewers, I too viewed many videos creating this circuit. Yours by far is the BEST of all viewed. I was able to build one, but still waiting for the screw connectors to arrive.I just used solder. You seem to be a most friendly man who knows how to communicate with others. One thing and if you can help, I am having trouble locating the resistor. I can find the 220 but it is the physical size that is hard to determine while looking online. Keep putting up the great videos...

Thanks, I watched so many and looked at somnay examples...this is the best thank you. Will definitely be following

Really like the CyberPunk design and am gunna steal it and call it my own 😎 Seriously, electronics is art and your designs and soldering technique is exactly the way it should be…..thank you

Your English very clear to me Thanks a lot for this video It's really helpful

You were right. Nice job 👍

I like the way he explains very patiently & & clearly 😊👀❤ that make me to understand well 😇 👀♾️🍀🍀🍃🙌👏

My Dear Brother, Your circuit making is very good indeed! and I appritiate your job undoubtedly! You have told that you don't know English language well! but once upon a time You were a teacher in profession! I think Your English was not so bad as you think. We had no difficulty to understand your conversation. Thanks a lot. My advance congratulations for your all upcoming videos.

This is exactly the last piece of the puzzle that I was looking for it's been about as fun as playing league of legends, but it hasn't been one hell of an adventure though.

Me gusta como trabajas lo haces que parezca todo tan fácil. Muy ordenado muy limpio muy curioso. Felicitaciones gran trabajo aunque es una chorrada siempre pero hecha con mucha inteligencia.

Indonesian watching, thank you for the content, good luck always. 👍👍👍🙏

¡ Thankyou vm, very useful, didactic and well done. Health for you and yours !

Fantastic video, good topic, and excellent English

Electronics is an international language, thank you for explaining it in English.

Out of all hundreds if not thousands the people that make these electronics / circuit videos, there's only a dozen or so that are actually watchable. Seems like they all have that same stupid obnoxious public domain playing too, lol. And from the good ones, only a handful are also entertaining. You fall into that category, keep it up bro! I've probably watched your power source / load videos a dozen times this week, really excited to try out some of these ideas.

Very nice and informative thanks !

Your English is fine. Thanks for the instruction

Good and thank's your tutorial... 🙏🙏

Nice video, thanks :)

Having a hard time with this circuit I'm using a 10K potentiometer and at higher voltages it adjusts normally but as soon as I get down into the three range it all of a sudden drops down to nothing I can get it to 3.3 volts but it doesn't stay there it wanders up and down even with the capacitor. I just realized I was using an old potentiometer as well I don't know if that could be yet I noticed that there was some soulder stuck to the leads so I obviously used it before

Very neat work! And your English is pretty good!

Thank you so much, I wanted to make this for my DIY cooling fan for my laptop. So it doesn't run at max speed all the time

Very versatile!

Wow sir that's awesome

very good ... hello I'm from Brazil 👏👏👏

Nice soldering!

Not a bit was boring dear, Your cam work focusing is great, And you are damn good at English .

You speek nicely make a video on transfomer binding i m from India 👋

Hj, can I use 35V incoming voltage? also it will be nice if you can send me the list of material. Thanks for your set up is excellent

Thanks bro brilliant video.

Liked and subscribed!

Thank you very much yuor explanate is very nice and Easy I try to make like this

I seen the smoke come up from the solder and I literally tried dodging it in real life. My friend please use a fan while soldering, you might think it may not bother to do it a little bit. But collectively over your lifetime that's an incredibly dangerous amount of lead to breathe in. Think about your safety not for yourself but for those that love you. Take care and thanks for the video!

very very nice sir I'm impressed to you

May I ask for your help with a diy battery to replace original ones that power heated gloves. I opened the case that houses two 18650 Li and a pcb that configures batteries in series. The pcb also has a press button that, when connected to battery, turns power on and selects between four power modes, 25, 50, 75 and 100%. I have spent hours searching for the same pcb but haven't found it nor one similar to it. Is there anything you could suggest that I do?

Your English is good, Sir!

Very good 👏

Your video is very interesting, I like it

Thank you! How to use same circuit to charge 8x1,2v batteries?

And you for this presentation,..I am curious of how to limit the current for a 1.25amp 12v fan, so I could have different speeds.

Oh my my , thanks for your good and calm English I loved your acsent really enjoyed and learned English is also not my language lovely explained video I liked & subscribed your channel 😊very good bye 💡

U explained so nicely..thanks..

Great 👍 video , can you maybe explain to me how to solder the good quality 10 turn potentiometer into this circuit?

Your english very clear

what happens when you load it and put amps through it? does it get really hot?

Well Done 👏

BRILLIANT AND ENGLISH IS VERY GOOD

Great video! The only thing I’d like to see is the schematic. Thank you!

I like this thank you

I have a question. I am trying to build something that is a bit unconventional to most people. I want to build a vape mod that is voltage regulated. I prefer to have a buck boost converter, but I cannot find one that is within the voltage specs that I am looking for. I want to have the ability to use either a single 3.7-volt battery or a dual battery 7.4v but it must have a 2.5v cutoff. I want to be able to adjust the voltage from 0v-10v on the output, and it must be able to withstand 30 amps of current, these devices produce a lot of amps running through the system and most boards I see can only output 2 amps which is nowhere near enough. Any help will be greatly appreciated.

When regulating to 1.5v does the LM317 dissipate more power as heat?

Not boring at all, thanks for teaching

..do we not have any DC voltage regulator above 12v.. example for Regulating voltage across mixed Solar panels in-between inverter.. let say I have 2*36dc 8 A but slightly different rating.. I want to regulate it's input voltage before it gets to the inverter... Is it available?

Very nice video Thank s❤❤

Excelente, el mejor de todos

I need this circuit to test mosfet ON OFF voltages. I will build this today.

Good job

Nothing to worry about your English, it's good enough... I am Srinivas from India.

i have done the cirucit, it was working fine untill i short the output wires, lm317 starts to smoke out. what would be the problem. the input power supply was 20 V with 4.5 A rating.

Good effort to improve bigginer skills . Love you friend

I had searched for a variable voltage regulator, but I was wondering if you could do it in reverse and increase the voltage from a 3.7v 10a-20a 18650 battery? Could this be possible?

Nice sir, but are the small lm317 circuits on sale from China good for dimmer low power 3V Leds?

Very Good Video, Can You Make A Video As Such With More Current Capacity And Or Control Of Current Also ? Thank You

Hello dear , your english is pfect . ı understude you hundert prosent TA3BS FROM TÜRKİYE

It can be work in 24volts ac ?? Just adding some bridge rectifier and a capacitor in part of an input voltage and the potentiometer will it burn??? Cuz mine i saw a bit simple schematic and i follow it but when i on it the potentiometer will keep burn and the lm317 is also damage so i should i do ??

Спасибо тебе большое. Такая схема единственная которая у меня заработала. Я спалил около 4 потенциометров.

I like IT. THX

thank this works

Hey thank you so much for this video. I got a question I am wondering why you soldered the potentiometer with wire connecting the two pins?

what is 10uf capacitor voltage rating?

can I ask? I have a Dc 3 volts portable fan and I want to run it with 18650 (powerbank) which is around 4,8volts. Can you show me what should I use to reduce the voltage which is not too bulky. An adjustable speed is ok I guess, to make it more interesting. Thx in advance.

What is the cap voltage ratings? I am on top of the Uf but lost for the voltage ratings..can I use up to 300 volts or 90 volts if those are made? Thank you so very kindly from Houston,Texas

Just asking why you are not using a heatsink for the lm

Voltage rating of used capacitors? Resistence watt?

how many watt do you recomend for the 10k pot ? i may want to use 60v

Excellent, but how much are the two capacitors and how much is the potentiometer?

Tell, am i right, is the input pin in the video on the right and output pin of the regulator on The left? All the stuff ivw watched the inout was in the keft, pin 1? Is the regulator just facing away from camera?

Nice video but I have some questions, why the resistor? Why 220 ohms , why ceramic capacitor in input? Why electrolytic capacitor at output and why u put less capacity in input instead of the output?
