Magnificent. I have done something similar but with only LM 350K. It can handle just over 3 amps. With a 24 volt transformer the output voltage is 1.2V up to 30 volt DC. Built in 1980 and still holding.

Aapka video ka dikhane ka Tarika bahut achcha hai Aisa koi itna saaf suthra nahin dikhata hai achcha Laga❤❤

I am beginner electronics, no education your video is help me alot

Great!!, what i was looking for and excellently explained for people like me, newbie in the electronics, thanks

Excelente trabajo, muy explicito y muy práctico, Me permito hacer una observación: En el minuto 7:40 sugiero que el cable amarillo debe ser conectado a la pata Vin del LM317 para poder así obtener lecturas inferiores a los 4VCD el resto: MUY BUENO.

Yeah like it too ja go the way he draws the wires makes it easy for me to understand and see the connection, Great stuff thank you E 😎

I have all these parts put aside to build a PSU similar to this but never got round to building it.. must put one together when im not mad busy. 😊

very informative and neatly explained with graphics too.. i have seen first of this kind.. WILL HELP ALL NOVICE STUDENTS.. FEEP IT UP BRO... YOUR GRAPHICS WITH ACTUAL COMBINATION IS VERY INFORMATIVE.... ALWAYS WE WILL LIKE SUCH VIDEOS.... TAKE CARE... YOU ARE GENIUS SIRJI... JAI BHOLE.....

thank you so much just because of you I learn excellent power supply

Connection is wrong.... But project is very nice

Excellent. Your method of explanation is wonderful and revolutionary in the world of electronic. It can be followed every one. So that a beginner like me can understand very well. Thank you.

Très bonne vidéo et surtout la manipulation avec Paint qui explique bien. Well very! intereting Thank's

Woo! nice idea friends thanks for sharing

Muy buen trabajo , limpio y practico. Lo voy a copiar, pero con un toroidal. Gracias!

The transformer is 12-0-12 Volt 3Amp. You are using it as 0-24 Volt 1.5 Amp . How it will give you 3 Amp current ? secondly the the meter is powered by out put of the circuit which is wrong. because if your voltage go below 4 volt(As it is a Variable Voltage Supply) the meter will go off because it needs 4 -30 volt Dc to operate. So it should be power on through the DC generated by transformer and the yellow sense wire should be connected to output voltage of the circuit.

Молодец мужик! Все так подробно и грамотно

Hello Your totos are well presented and nice. But having made feeds with thypons (printed circuits) for high schools with high school teachers (between 1998 and 2011) I would have a suggestion on security: the food should be secure, either in a wooden box as you show not PVC but closed, to avoid electric shock. cordially Patrick France

mis respetos para todos los que nos enseñan su trabajo y de los cuales he aprendido mucho,..pero este se me hizo muy bueno,..excelente

Excellent demonstration and it is helpful to students ,hobbyist and application engineers in the field of electronics !

Excelente video, yo tenía problemas para conectar el display digital en la fuente y solucioné. Gracias por compartir!

Really good explanation thank you. Vary valuable. 👏🏼

Best teching method.... Thank u....

Muy buen trabajo, si le conecto un cautin para regular la tension se caera esta.

يبدوا صاحبنا من الهند احسنت ... واصل

fiz minha fonte ingualsinha a sua fucionnolu perfeitamente, no lugar do potenciomentro coloquei um zerner de 13 volts e no lugar dos trasitores 2n3055 coloquei os bipolares mje 13007 . ta com 13 voltes de saida e uns 20 ampres fuciona muito bem em um som altomotivo

La caída de tensión es horrorosa,más usando un lm317...tendrías que poner las resistencias de 10 watt que están en paralelo a la entrada del lm317 y colector del transistor.

I really liked how you showed how you did it. Great job, but it does look (FUBR)

Great video .... Thanks

C'est parfait . De plus, je ne trouvais pas la solution pour brancher ces foutus Voltmètres/Ampèremètres chinois ... se repiquer sur la masse DC du pont de diodes.... je n'y avais pas pensé.. Il faut dire que le net est truffé de montage à la con.... surtout quand la source d'alimentation est unique... Merci!

may I suggest, connecting the 270Ω resistor to the output end of the parallelled 1.5Ω resistor instead of the output of the LM317? That would compensate for the voltage drop in the emitter follower resistors, keeping the output stable from no-load, to full load. (leave the capacitor connected as is, for stability) The LM317 works by making sure the reference voltage between the adj and output remains exactly the same. If voltage drop appears across the 2N5532 and the resistors connected to the emitter, it will automatically compensate. That makes it a true regulated supply. You should not see any change on the volt meter, when connecting a light bulb or motor. Connecting a couple of diodes in series with a low resistance between the output of the large resistors and the BASE of the 2N3055 will limit the current that the transistor can conduct, in case of a short circuit. Make the value low enough, that the current limit built into the LM317 can protect itself, as well as the power transistor.

Muy buenas . Muy bien por la presentacion , la musica Ok . y el video way , pero podrias enumerar los materiales utilizados . un saludo . GRACIAS ..

Super sir Really great It is very clear Can you send me the components list

asi es que se deben de explicar los proyecto lo felicito ya comparto el video excelente

Good idea you explained how to connect one by one

Very good .nice explain.

Boa idéia vou fazer aqui também.

HOLA, MUY BUENO. GRACIAS desde Argentina

you will be a successful youtuber not immediately but definitely

Excellent project

What's the point of the two 1.5 ohm resistors? As you can see the voltage drops from 13.3V to 12V. That is not a regulator, it is a simple emitter follower. In order for this to be a regulator you need a feedback to the output of the LM317. That's why it doesn't work properly.

Mr beauti full design and development very good project thanks

Excelente tutorial que ya lo reproduje, mi inquietud es si le puedo poner un transformador de 30 voltios ya que no tengo experiencia en electrónica solo lo hago por pasatiempo que me quedo de la pandemia del virus-19 en la que no se nos permitía salir de casa. Gracias

That 270 ohm resistor would better get connected directly at the output, and this way you have a more stable voltage when you put a load on it.

Very good sir love you so much,😍😍😍

Yellow wire out mai denathaa aur amp meter ke .. black n red series connect negative battery's ko dete too aapko amo bhi dikhyaga aur .. relay dalte to auto cut hota

Сильно просаживает.

Great video as always .Keep the good work sir .You are the best teacher .I have learned a lot from you 😁

I was impressed what you shown how you connected the components , can you please show two light automatic indicator,(Green and Red) and name's of each materials, I am not electronic profession but i want to make my own battery charger with your presentation also don't use board diagram i don't know how to use it, Thanks.

Nice idea friends thank.

Is there a way to connect a Potentiometer for amp adjustments? and add 1 more power transistor as well? thank you btw you articulate the steps wonderfully thank u:)

Deveria ter colocado o esquema eletrico com os valores dos componentes.

Brow...u r presention is superr...awasemm.....keep it up

good viedeo

Very nice, regards from Brasil !

Hello friend, good morning, good project, the one you explain in the video, I really congratulate you. friend I have a transformer of 31v and 7 amps, tell me, I can use it in this project too, please, if it were kind, tell me yes or no. take care and thank you.

SUPERB SOLUTE LOVE FROM PAKISTAN

Why you use 2 Resistor at the OUT voltage?

Muy bien, excelente trabajo

very practical and objetive, thank u !

Good video, I chose it among all to do my voltage regulator. Greetings from Colombia

This is voltage regulator IC , not a transistor, its Called Pass transistor used for incising current, not controlling voltage, you dont need this transistor for voltage regulation . Lm317 will cut it , up to max 40V , that is about 25V Transformer .

Super

Mantap

Very good

Excellent

Great word

good video and helpful.

ok, muy buen video, saludos desde Argentina!!!

have an arista power suppluy with that 2n3055 transistor need to reconnect that transistor to board any ideas where those wires of base emitter connect

muy linda la explicación solo que no enseño lo del led y el valor de la resistencia

thank you for your video.

excelente amigo thankyou my freind

Gracias

An excellent video, and very useful! Thank you, sir!

THANKS

GOOD GOOD AND NICE WORK THANKS

este si es bueno..pocas palabras y mucha acción :-))

Your channel is awesome! And of course You have received the registration button from me

good job more video...

great product thanks can you please make same product 220v ac to 450v dc

Nice

Great job. Sir i Fail to understand the usage of power transistor and other components like resistance1.5 ohms,capacitor and small cap.the similar adjustable power supply can other wise be made. Kindly advise and guide to remove my doubts please. Regards

good vdo . sir ......but sir iss se hum 12v tractor ki badi battery charge kar sakte hai kya???????. plg tell me

Excelente. fuente muy buena. Una pregunta maestro cómo conecto la resistencia shunt que vino con mi multimetro, es igual al del video. Gracias desde Veracruz México.👍👍👍👍👍

What are the components and cable size for the adjustable voltage transformer and is it for 110v or 220v? I'm new at this but I would like to learn, never too late.

Ini sangat bagus saya hanya bisa meniru... Saya mempunyai travo/Transformers 4A untuk komponen yang lain ada yang harus dirubah.. Tolong jawab

Amigo aqui uso a rede 110v. Este funciona em 110v Ou as peças são diferente? Grato por compartilhar. Parabéns!!

hello, nice video, but i have 2 questions: 1/ why put 2 resistors at the output ? 2/ why this voltage drop with the light and how to reduce the voltage drop ?

maestro ante que todo saludo y un abrazo . me pregunta es que pasaría si yo uno las dos puntas o sea el positivo y el negativo de los voltaje de salida ¿ abria un corto ? se lo pregunto porque yo diseñe una muy presida a esta con la diferencia de que le coloque un LM317T y cuando unía esos voltaje de salida me daba un corto y me quemaba los diodos rectificadores. se que las que tienen protecciones se apaga sola pero las que no tiene maestro ¿ hay que tener cuidado y no unir estas voltaje ?deme una orientación maestro gracias y disculpe u otro colega que me oriente

que buen tutorial gracias, pero por favor podrías contarme cuanto es el voltaje máximo? por tu ayuda mil gracias

What do you think if they only use an LM338 that is 5 amps ?, so only the LM317 is replaced and it goes straight out without the need for the 2N3055 ... I appreciate your opinions, regards!

muito bem nota 1000

Amigo donde esta el Link del plano para descargar y hacer esa fuente

The best ,i like

Sukses and berhasil

beutyful

Estimado tenga usted mis saludos. El circuito lo proyecté en Multisim (Simulador de ctos.) y al llegar con el potenciómetro descrito de 10k, sobre el 50% el voltaje no varía. El rango de 1.2 a 22.2v solo se obtiene cuando reemplacé el potenciómetro por uno de 5K. Saludos.

Good work, I've 24-0-24 5A transformer lying around, kindly drop me the components list or should I use the same in the video.??

Bonjour, magnifique vidéo 😄. Je débute et j'ai une question : -Je souhaite utiliser le lm7805 afin d'obtenir en sortir une tension de 5v à partir d'une tension d'entrée déjà stable de 24v. Dois-je obligatoirement utiliser des condensateurs en entrées et en sortie du régulateur car la tension est déjà stable ou puis-je utiliser simplement le lm7805 avec en entrée ma tension de 24v dc ? D'avance merci pour ta précieuse sollicitude 😊. Cordiales salutations.

por lo que vi al someterla a carga tiene mucha caida de tension, no es una buena regulacion, el voltaje no se mantiene con un consumo de casi 1 amperio o el transformador no tiene una buena relacion de potencia amperios, si es de 3 amperios, con esa carga de 860 miliamperios no es para que se caiga casi 2 voltios, seria aceptable una caida de 0,6 voltios a travez del transistor de paso.
