Dear Sir, Not only your politeness behaved amaged me! but also you are a simple gentle person! it's my feelings to you ! I am a young man of 76+ , passing my liesure period watching various kinds of videos in you tube. Electronic job is hobby! and a little electronic job I am very much fond to it ! Sir , who told you that you don't know English well ! Your politeness will covered all your defect ! My mother language not also English? But somehow I managed. I was a former Executive of SAIL( Delhi) . Retired on 2008 . A lot of thanks for your knowledgeable as well as informative video too. Please stay well and be happy to make new video for us. A lot of thanks with warm regards Sir.
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
Your English is clear and great, the content is superb
Plain and simple project with explination makes it very interesting aswell as likable.
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.
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.
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 RUclips. YOU ARE A VERY, VERY GOOD TEACHER THANK YOU
My students never listened :) Thanks for sharing.
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.
Thank you for this comment😀 i am glad you find it entertaining and useful.
Best and uncomplicated circuit presentation I have come across. Thanks for sharing.
How can you add a voltmeter screen to this to see what you setting the voltage to? I added one to the output but No mater what I try it fails. Not sure why
@@skor1873what do you meant by it fails? Like it drops voltage or just turns off or blank
This was interesting and thank you for the great camera work it’s easy too see what you are doing. 👏🙏
Great video mate. And your English is very good. Can understand perfectly.
I try this. Success. Thanks a lot.🙏 from India.
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...
Your English is good, Sir!
Thanks for a great video. Easy and clear understanding with pretty nice communication.
hvala ti puno
Спасибо тебе большое.
Такая схема единственная которая у меня заработала.
Я спалил около 4 потенциометров.
Your English very clear to me
Thanks a lot for this video

I really liked! Thanks from America!
Not boring at all, thanks for teaching
I did enjoy your video- relaxed, entertaining and informative ! Thanks !
Very Good Video, Not Boring !
Thanks For Your Time & Effort 👍🏼
Hi i am Mohiuddin sheik From India, i like your electronic tutorials, sure your good in making tutorial videos in electronics. im basically an electrical Engineer served as electrical engineer in Gas Turbine power plant in India and 15 years in Kuwait. i am very much interested in making electronics projects, but i am not perfect in Electronics, i have 30 years of experience Electrical but not in small electronics projects.i can understand 132kv transmission lines 132kv/440 vlolts Transformers, not soo good in 220 volts /12-0-12 volts. i am not basic learner ive some knowledge. but in electronics not buck boost convertor like you. ill be following you and see your videos . want to learn from. Thank you.
Mohiuddin sheikwe all started without sufficient knowlege in a new area. Keep watching these videos but if you want to learn try and build them it's how we learn. The more you build and often break the more you learn. I learn more in many areas including electronics every day. Dont give up. I will be 72 in October if I can do it you certainly can too. From Down Under in Australia.
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 💡
Nice videos! Like the way you explain these things!
But you could work a bit on your soldering skills 😉
Never „carry“ the solder with the soldering tip to the soldering point.
Pre-tin both sides, then clean the soldering tip again and then solder the two spots together.
Thank you for advices.
Hi , I like the design of yours , good this project to regulate the fan motor on Fume exhaust that I has building.
Thank you 🤗
Your english very clear
¡ Thankyou vm, very useful, didactic and well done. Health for you and yours !
Thank you very much yuor explanate is very nice and Easy I try to make like this
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.
Great video! The only thing I’d like to see is the schematic. Thank you!
what is 10uf capacitor voltage rating?
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.
don worry,, i like your video. thumbs up !!!!!
I need this circuit to test mosfet ON OFF voltages. I will build this today.
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
Why do you need add a capacitor ? How`s the effect? I have seen video from other channels, nothing added. can you share , I want to get to know more. Thank Q
Dear Sir, a) the big capacitor is 0.1microF, how about the working voltage? b) the small capacitor is 10microF, how about the working voltage? Sorry to say that I have no knowledge in electronics. Just started to learn. Hope to hear from you soon. Tks.
You were right. Nice job 👍
U explained so nicely..thanks..
No problem, thank you😀
Why is there connection on potentiometer between output and adjust ?
Very good 👏
Very Good Video,
Can You Make A Video As Such With More Current Capacity And Or Control Of Current Also ?
Thank You
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?
Very versatile!
Izvrsno zemljače. Ohrabrio si me da napravim regulator za malu željeznicu umjesto originalnog starog Mehano. Radi fino jedino što napon u tračnicama ne pada ispod 1V. Ali ionako da bi se vlak pokrenuo treba mu bar 3V.
ajde drago mi je da sam pomogao :)
Poslao sam mali video testa, i to 2x ali ne vidim nigdje da je poslano. Nadam se da je stiglo. Još trebam ugraditi polarity switch za naprijed nazad te sve polemiti kako treba i složiti u kutiju. Prethodni projekt mi je bio brzinomjer za male vlakove preko Arduina. Nisam se odvažio objavljivati na RUclipsu. Vama svaka čast i moja podrška za daljnje projekte i objave.
Di ste poslali?
@@VolosProjects poslao sam kao odgovor ali izgleda da se ne snalazim u tome.
Thank you! How to use same circuit to charge 8x1,2v batteries?
Wow sir that's awesome
The maximum supply input is how many volts sir..?
very very nice sir I'm impressed to you
Disculpenme por pregunta sin abrir la reseña, ya vi que el potenciometro es de 10k, la resistencia es de 220 ohm, el capacitor de salida es de 104 uF y el capacitor de entrada es de 10uF, Excuse me for asking without opening the review, I already saw that the potentiometer is 10k, the resistance is 220 ohm, the output capacitor is 104 uF and the input capacitor is 10uF, este es el mejor proyecto de estos reguladores,,
Good and thank's your tutorial... 🙏🙏
Great 👍 video , can you maybe explain to me how to solder the good quality 10 turn potentiometer into this circuit?
Thanks bro brilliant video.
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 ??
Circuit layout also great for cooling the lm317 😅😅😅
What is the voltage of the 10uF capacitor? Thanks!
Sir, if I use a negative voltage input and the output becomes a positive voltage, can I use that IC? If not, how do I find the scheme I mean? Thank you sir
Привет колега подскажи как несполить ли 317т резистором регулировочным
Nice....it can handle 40v.
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?
This wire is necessary to connect the 220 Ohm resistor to the adjust pin of the LM317
..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?
You didn't mention the values of those capacitors..
Well Done 👏
Nice sir, but are the small lm317 circuits on sale from China good for dimmer low power 3V Leds?
why is your schematic different than your soldering , i cant se any dirct connection between 1and 2 on your pot ,in the schematic
Looking at it again, isn't the whole thing flipped? Working from right to left...so the LM is obviously facih away from camera
how many watt do you recomend for the 10k pot ? i may want to use 60v
When regulating to 1.5v does the LM317 dissipate more power as heat?
what happens when you load it and put amps through it? does it get really hot?
I am not finding the circuit diagram which necessary.
Sir please tell me which value capacitor and resistance you use ?
am i correct: you connected the heatsink (you said also is the output) back to the ground and into the potentiometer ..... does this save power? does it reduce the heat of the regulator?
oh no... thats your output...... ok sorry i just came from a video where the guy measured the "output" from between the two resistors and ground.... which means he was reading the wrong voltage for "output". he was on a breadboard and he confused his own circuit.
Cool
Also make it attached with bridge rectifier ac to dc
What value of capacitor used at out put
can i use this for my vape setup? 2 batteries 3,7V 35A each
This can only handle 1a
Voltage rating of used capacitors?
Resistence watt?
I'm new to electronics. What is the different between this circuit and voltage divider?
Hi friend. Voltage divider is used for command but this circuit is used to make regular voltage and current to activate any load working under the battery source as well.
Сколько ампер? Сможете сделать 60 амперный на 12 вольт для автомобильных вентилятора.
Can i use 103 trimmer?
Resistance capacitor wats and other details please ❤
What is the stand you are using?
Can I use misfit z44 or 3205❔
عالی بود
thank this works
👍👍👍👍👍 explanation
What is the current that LM317 can handle? Say, can it handle 7A at 8.4V?
1A is max
Can I get the value of capacitor.
Jeli može da se poveže više ovakvih regulatora paralelno na isti potenciometar, imam trafo koji daje 30A i mislio sam da napravim jedan power supply ali me interesuje kako da regulišem struju A ,imam na umu da regulišem napon i struju na izlazu individualno
Stvarno ne znam, nisam nikad trebao takve amperaže. Al nekako mislim da ces morati neki drugi način nac.
How much AMP out put?
رائع
I like IT. THX
