Adjustable Voltage regulator LM317 how to make!

[@funnyworld5482]

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 KZbin. YOU ARE A VERY, VERY GOOD TEACHER THANK YOU

[@roo1871]

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

[@djredphoenix6671]

[@dustinbrown7601]

Not my first circuit but very explanatory thank you good work

[@Deepaksingh-tn8eh]

Just go on Google and it will take you to perfect working videos

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.

[@owenvinall9970]

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

[@gamesbeforedames]

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 KZbin. 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

[@vincentperiolat4610]

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

[@ccv3237]

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.

[@davidstephens189]

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.

[@SunilKumar-ee2pz]

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

[@akashtechguru8190]

what is 10uf capacitor voltage rating?

[@ConceptXX]

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

[@Tsnafu]

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

[@disguisedcat1750]

Pleasing to look at

[@mehomut]

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

[@Aston3003]

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

[@JWest1]

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.

[@robertobravo3563]

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

[@dfn808]

My students never listened :) Thanks for sharing.

[@anantalalsarkar5345]

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.

[@VolosProjects]

Thank you my friend:-)

[@gabrielmassa]

Great video mate. And your English is very good. Can understand perfectly.

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.

[@owenvinall9970]

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.

[@RalphPoggenpoel-gq1by]

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

[@attilarivera]

your english is good,, what u need is to improve your soldering technique... LOL

[@kiranshashiny]

The output voltage keeps fluctuating 11,1 to 6.83V and different values. Nothing changed after or before the 10uF capacitor. I could not use this project the way the circuit was explained. Maybe I missed something.

[@somerandommadman38]

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.

[@wavescomplete5085]

Why i follow this i just got failed many time.. But easy for me use mosfet/power transistor for variable voltage....I can close my eyes

[@arnoldpadolina85]

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 ??

[@Bladder777]

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?

[@georgemc5924]

Thanks for a great video. Easy and clear understanding with pretty nice communication. hvala ti puno

[@kadarsetiawan3461]

The maximum supply input is how many volts sir..?

[@isitoone1180]

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

[@chongshenchang9367]

You didn't mention the values of those capacitors..

[@DennisMurphey]

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 try this. Success. Thanks a lot.🙏 from India.

[@gullinbursti]

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.

[@VolosProjects]

Thank you for this comment😀 i am glad you find it entertaining and useful.

Why is there connection on potentiometer between output and adjust ?

[@hobikidalbadminton]

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.

[@reinerk.7856]

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.

[@VolosProjects]

Thank you for advices.

[@PyricDemon]

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?

why is your schematic different than your soldering , i cant se any dirct connection between 1and 2 on your pot ,in the schematic

[@Bladder777]

Looking at it again, isn't the whole thing flipped? Working from right to left...so the LM is obviously facih away from camera

[@stinger220]

why would you solder output to ground? Wouldn't that short out?

[@codyswanson8481]

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!

[@CorneredCat0]

Yeah, dodging at least will do if there's no fan

[@arrrgoyle5695]

@@CorneredCat0 Sorry to disagree. I have enjoyed the smell of solder for >60 years.

Thanks alot sir , can you tell me the value of resistance?

[@ConceptXX]

Oh brother lol. Instead of repeating things other people have said, research it yourself first. Then if you still believe you're comment has merit, you will be able to tell us why. For now though, I believe you're telling fibs and making everyody scared and hiding under the bed when soldering, including me

[@mrgreggwinfrey9298]

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

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

[@contentoso]

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,,

[@kapoioskapoiou8631]

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?

[@surenbono6063]

..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?

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...
