Computer SMPS "Hacked" into Variable Lab Bench power supply 

SUPERB ! This is the BEST, MOST USEFUL project I have seen on youtube ! You made a versatile PS costing thousands of rupees from SMPS of a scrap PC ! SHABBASH ! Congratulations for such a brilliant job, it not only gives a useful money-saving product, but also increases our knowledge. Finally about the Arduino Voltage-current display : Doesn't matter if it is costlier or takes lot of time. Whoever wants to learn about Arduino will do it, and whoever wants PS immediately will buy Multimeter/Panel-meter

Sar aap bahut acchi tarah se samjhate Ho. Isliye बहुत-बहुत dhanyvad , Aapka har video bahut achcha hota hai dekhne per maja bhi aata hai aur bahut sikhane Ko milta hai

I'm also an electronic enthusiast bro just super impressed by your knowledge in basic electronics

A lot of good knowledge in this. I'm trying to make a buck convertor using tl494 and this might help me in building.🙂

Very hardworking person.good job.

Sir u are awesome, your teaching techniques are very good 👍 thanks for this ,

Great her technician ko kam dam me useful Keep it up display Ka detail video Devo amp digit 4 or 5 Milli amp dikneko koshish banav thank you your job

you are different from other hindi youtubers. keep it up

অনেক অনেক ধন্যবাদ ও কৃতজ্ঞতা। আপনার কাছ থেকে অনেক কিছু শিখেছি। তার মধ্যে এটা খুব প্রয়োজন ছিলো আমার। একদম নিজের মতো করে মোডিফাই করতে পেরেছি। কিন্তু দাদা, একটাই সমস্যা, সেটা হল চপার থেকে নয়েজ আসে। আমি ডিলে সার্কিট ঠিক থাক মতোই লাগিয়েছি। তবে ভোল্ট একদম বাড়ালে নয়েজ অনেকটাই কমে আসে।

Sir maine notification on kiya hai lekin mujhe notification milta hi nhi mujhe apka channel search krke new video dekhna padta hai

Good tiching karte hai 👍👌👌👌👌👌👍👍👍👍👍👍👍👍

So detail explained..... Very very useful...subscribed

Superb job, please explain practical connection of your Volt & Ammeter connection (LCD)

Very good sir nice video age video continue please good nolegbale video volt and amp Miter ka video continue please

Apni khub bhalo bhojan

Best explanation

Sir game ap ka video bahut pasand Aya very good video sir hame volt AMP Miter market se nahi karida ham use banana chahte hai pls ap us video Ko banayiye hame us video ka intajar rahega thankyou.

Arduino code and circuit diagram?

U have great knowledge in electronics, I have personally tried to find this setting for variable voltage and current, but miserably failed.... Thank you sir

Aap bahut acchi tarah se samjhate ho thanks One request plz voltage divider formula ka video bana a

INDIAN GREAT SCOTT!

Itna sara dimag kaha se lagate ho yar hm to ye jan jat me nahi karte he shop me milta he vohi us karte he.good mine yarr 👌👌👌👌👌👌

Reflection Ur ✌️✌️✌️ hardwork

Wait kar raha tah.....😍😍

Sir kya baat hai.... Maja aa geya

Bhai maan gaye. ❤

Knowledge bahut hai aapke pass..... Great...

Very good. Sorry excellent 💯👍

sir ap abhout inteligent hai

Dimg ghum gya 🤯🤯🤯🤯🤯

👌👌

Dada apner to pochur Knowledge. Apni electronics jonno ki kono spacial course korchen, pls janaben dada . Amar o electronics details a janer khub iccha ache

Darun laglo ❤️❤️❤️but ami jodi ampere ar short circuit protection circuit er kono setting change na kore only voltage ta barai tahole kono problem hobe? Karon ampere ote 20-25amp day full load e jeta sufficient but amar shudhu voltage ta baranor dorkar seta ki kora jete pare? Please bolben comment er Opekhay roilam. 🙏🙏🙏

Genius.... darun sir ❤

Aaj isko banaya aapki help se....but kuch question hai..... Q1. Jo fan cabinet main install hai wo bhi voltage ke sath slow fast ho raha hai....kiya ye sahi hai ya galat....? Aur iska rehena jaruri hai...? Q2. SMPS se noise aaraha hai...kiya isse problem hoga...?

I think one of the best looking because of that display and great reverse engineering

Good tiching 👍👍👍👍👍👍👍👍

I am 3rd comment er love you sir

Master

Kya 12v5A adapter (13.2v without load) se kya 5Ah bike ki battery charge kar sakte hai?

👏👏Osm 👍👍👍👍👍👍👌👌👌👌

Sir aapne bahut hi achhe dhang se explain kia hai. Sir circuit diagram kaise download karte hain , us per v ek video banaye. Thank u.

Bhai mujhe 12 volt se jyada chahiye per jab increase kerta hu toh automatically shut off ho jata hai. Ushke liye kya kerna hoga?? Mai chahta hu yeah feature 20Volt per trigger ho.

👍👍🙏

Excellent 🤝🤝🤝🤝🤝🤝

🙏🙏

Is voltmeter ka code and connection chahiye.

Bro Transfomer noise ker raha hai per jab out put ke ground ko apne fingers se tightly pakadta hu toh noise ekdam na ke barabar ho jata hai ayesa kyu?? Iska koi solution hai?? Please help😊

love u bhai superr

Nice

Sir ji.... Iss mein sirf 14v banaye 12v ko, jisse car ki 12v battrey charge kar sakte hai... 🙏 Aapki valuable information ke liye wait kar raha hu 🙏🙏

Great work

Power supply konsa company ka hey?

great

দাদা, প্লিজ উত্তর দিবেন। সব ঠিকঠাক মতো মোডিফাই করেছি, কিন্তু এম্পিয়ার ৫ এর বেশি হলে ভোল্টেজে ড্রপ করে। সর্বোচ্চ এমপিয়ার ৮ দেয়, তখন ভোল্ট ৮ হয়ে যায়। আমি RT 18k রিপ্লেস করে 15k লাগিয়েছি। চপার আগেরটা থেকে আরো বড় একটা লাগিয়েছি। কিন্তু amp বাড়ছেনা। এখানে মূলত amp কিসের উপর ডিপেন্ড করছে?

Can we make constant current source using a linear transformer and transitor

Mains voltage jan leva hota hai 1min me mar sakta hai, mai agar 59sec hatt lagau to safe hai na ?

12v battery charger banao jisme battery full charger ho jane ke baad power auto cut off ho jaye jaise mobile battery me hota hai, aur gadi me hota hai.

Bro please help Maine sab normal kar diya SMPS mai 12v bhe aa giya per transformer bhot awaaz kar raha hai... IC ke konsi pin check karu

Mere power supply me EST.7502 IC laga hai to kya isme ye trick work karega

Bhai pura circuit appne jaise dikhya maine bhi waise hi banaya. Per mera power supply on nahi ho raha fan jab power switch on kerta hu to fan 1 sec ke liye ghumta hai aur phir band ho jata hai. Output per voltage check kiya kuch nahi dikha raha. KA7500 ke 14 pin per approx 5V aa raha hai.

I have psu with another ic how can I do this

Sir atmega328 volt & current meter video b bnao jo ap ny bnaya he

Khichadi paka di Bhai tumne 🤗🤔🤔🤔🤔🤔

Brother ye bala digital volt meter cahiye kahan se mile ga please 🥺 bolo jo video me use kiye ho

Sir a 36 volt variable power supply

Isme max. kitne amp. Ka battery charge ho payega..? 12v..

Sir mere mein IC number hai CP7520D. To isme kya change rahega?

Load resistor 0.1 ohm (5w) ki jagah 0.5 ohm chalega...? Kyon ki 0.1 ohm (5w) resistor nehi mil raha hai abhi....

Vai me buck converter laga ke ek charger banaya tha. usme savi phone charge ho ra, lekin redmi ka koi phone charge nhi le ra, sirf indication aake chali jati he, me usb ka body ko bi ground kar diya koi solution batao, redmi ka koi vi phone power bank or charger ke siwa kisi or se charge vi nhi ho ra

Make a video of electronics ballast please

hc8012bx16 ic detasit chahiye a computer power supply me laga he adjustable hold and current please my help my

Atmega328 ke .ino file mil sakta he? Please. I want to make it

Maine v asisa banaya he but only adjustable voltage per usme output short honese bar bar transistors short ho ja raha he . Short circuit protection hat geya ha koi solution batao plese🙏

Bhai ossiloscope wala video kab aayegs

Bro please help. Please reply Bro maine Apne SMPS ke voltage already 14.2v pe set kar le hai ek resistor ke madat se. Aur merko SMPS se battery charge karna hai per SMPS current bhot zada de raha hai merko usko 5A pe limit karna hai bus ... Vo kaise karu ..

Bro dth powersuply se banao...❤️❤️❤️❤️

Mera psu main AZ7500 hay. Isme kam karega???? reply plz😰

वाल्ट एम्प मीटर कैसे बनाये उसका वीडियो बनाइये

4 pin ko set kar ke hm AMP bada sakte he.

Ardiuno voltmeter kaise banaya hai

Bhai mere pas jo SMPS hai usme only one 2003 ic lga hua hai kaise ban payega ..... 😭😭😭😭 Bta do plese ❤️❤️

Sir ji namste Voltmeter ko banana jarur batay sir ji

How did you make cutouts in that metal case please I want to know

Mere psu me eak ic laga hai please batao kaise kare

Arduino & display ki alag video banao sir please

Open the English translation teacher 😊

Bhai muje arduino ka code aur circuit diagram mil sakta he kya pls

Sir mera power supply mein tl 494 nahi hai lm 324 hai kese kare please diagram dijiye?

Can I modify only pin no. 1 and 2 of KA7500 ic.... If I need only increase voltage....??

Bhai yah display ka tutorial banaa do please

I have done that modification . Work well but main issue are lot of ripple volt at output. It is not useful modification to use it as electronic lab bench power supply.

My PSU consist of 7520 IC ........... can i apply your idea on this ic? shall it work?

Sab se achha ye to ap ne display lagaya vo. Ye kese set kiya he ap ne vo thik se bataye

How to power that 12V cooling fan sir??
