This above video was really fantastic and i should appreciate your cool teaching skills. Kindly do come out with the updated one with feedback circuitry while i go through your entire series of videos . By the way your explanation of formulas for resistor values and capacitors were too good. Thank you.
Thanks 😊
I ll definitely upgrade this with feedback
Wow..Sir Excellent...I liked and enjoyed your video... Very Informative and Educative....God Bless you
Thanks 😊
Do like and share with your frends too
You are excellent. Got much confidence in electronics. I want to make a auto on off fogger system for my greenhouse operated on 12 volt. 10 seconds on and 10 minutes off with automatic repeating cycles. If you can make a 12v dc timer with on and off time regulated , it’ll be of great help for lakhs of farmers also. From market if we purchase all the gadgets it will cost not less than 28000 Rs. I watch all your videos and use it for my agricultural projects which is proving excellent. Your knowledge is excellent. Salute to you. I am a retired lecturer and now looking after agriculture. Thanks
You can easily make a timer using any Microcontroller or arduino
For that you can follow my arduino series you will find many videos related to your query.
Thanks

Hello Singh Ji, Your video Tutorials & Mode of Teaching is very nice. Please give me an idea to make a Dc Regulated Variable Power Supply From 0 to 30v & 0 to 10 amp.I have a 24v SMPS Power Supply with 10 amp output.How to use Buck Boost Convertor with it to get required stable output voltage & current.Also mention how to use separate digital Volt & Amp meter for monitoring voltage & current.Thankyou.
Sir agar me ek 2n3055 use karu toh yeh circuit kitne amp pr work karega?
I made a charger using 12-0-12 5amps transformer and 300w buck converter to charge 24v lithium phasphate battery but charging current is not increasing above 0.75amps.pls give me any solution.
Can I reduce the voltage and current of 24V bus battery using this circuit?
Can we use bu 508 instead of 3055
(Because i have bu 508)
Please reply..
Sir maine ye sircuit banaya to nahi lekin aapne diagram me 317 pe jo input diya wo 1no. Pin pe he usme koy galti to nahi hai na?
💯👍
Thanks
That is nice.
A simple way to make a variable supply. But we could not use it practically.
Using Buck Converter the voltage and current can be stabilized.
We can make a good variable power supply from any old computer SMPS using Buck Converter.
Try to make a project from SMPS.
I ll do it
Bd139 ki jghe or kon konse tr. Lga sakte h
Excellent video. I want to make a similar power supply but with feedback circuit and controller. If you could make a video for the same.
I ll try
This video could be perfect if you made a all new circit .. rather than using that old one.. so that concept of connection would be christial and clear.. please do not take this cmnt in a wrong way i like your channel and as per my point of view i have given you a feedback
With controller power supply is required. Pl. Explain.
great but current ko without load kaise set kar sakte???
Wind turbine se kitni coil turn se kitne size se kitna volt aur kitna ampere banega vo kaise pata chalega ,

Sir make part 3 with feed back circuit
Hello Mr Singh , after watching this clip I have one problem . Will this circuit work on a fluctuating pulsating DC input and give a constant out put .This I am intending to use on a 6V dynamo of a car to charge a 12 V battery as 6 V batteries are unavailable . The output of the dynamo increases with RPM and is pulsating between 0 and the positive voltage . Thankyou
To charge 12 v battery your input voltage should be greater than 15 v
Above 15 v it can regulate and provide constant output
Hello bhaji can you please make a video of battery charge auto cutoff with transistors without relay thanks
Why heat sink not used for voltage regulator 7812 ?
Can we connect resister to led both end to glow it or register should only be at positive side of led?
You can connect resistance any side of the led
10/10
Thanks

सर, क्या यह display reverse voltage/current show कर सकता है जिस प्रकार से multimeter में show होता है या फिर damage हो जाएगा?
Hi
Could this power supply be used to run a 12v car amplifier (to power a subwoofer)
Yes
@@TEKNOISTIX im impressed to see such promt reply by you. Really appreciate 🙏.
I just checked, my amplifier ouputs 250w rms
Pls upload a schematic (circuit diagram)
HELLO SIR
I have made this circuit. It is almost working fine except the output voltage. i have given the input power of -12 and +12 from smps. It voltage in the input side is 23.8 but out is 22.3 and is not increasing. yet it is decreasing to 0 but not increasing may i know the reason, where i am wrong. i have put 200 ohms resistance at the place of 220 ohms at mossfet and potentiometer. Rest all the value is as same you explain . kindly suggest.
These little drops occur because of diodes used
Every diode have its own knee voltage
So don't worry if you are getting 22.8
Its a 100% working project
عاشت ايدك بس المقاومه النصف متغيره شنو عمالها
Sir feedback circuit video
How do we make this PS short circuit protected at output for full voltage & full current?
Short ckt protection video is also available you can add that circuit with this
SMPS and Power supply both provide us DC Outputs, so why we use it in different equipment ????
sir 12-0-12 transformer hai to two filter caps 4200mf/50v series ker ke center tape ko dono caps ke center me jod k bhee kaam ho jaeyga. coments me picture send nahi ho sakti nahi to bhej deta. +15 0 -15 center refrance se. 0 +30 from ground refrance.
7812 ke jaroorat na padey shyad fir
Useful vedio,me janana chahta hu ki,agar 5v ki 1amp ki led h,or sath variable supply lgate h,agar current ko 1amp set kre or voltage ko 5v se down krenge or jab 5v constant rakhe or current ko 1 amp se down krenge to dono time me led ke liye difference hoga,
Me difference nhi samaj pa rha hu,
mujhe question nahi samjh aaya
Can you measure its VOLTAGE Regulation (No load to Full load Voltage Change) and ripples
Done in comparison video of voltage regulator and buck converter
Hii, can I add Darlington pair at power transistor to amplify current as I don't have 10 amph transformer or if there is any other way to do this then please tell me as my father is telling that if I didn't make anything working then he won't give me money to future projects
Firstly you need a source
If you don't have a 10 amp transformer
Then make a 5 amp supply amplifying currently will not give you a reliable circuit
toh bhai feedback kaise use kare or kya hota h wo
Plz design with feedback circuit
I ll do it
Bro pls upload the proper schematic diagram of this updated version of psu...and if possible try to give us the gerber files of ur circuits...that would a very great addition to your already fantastic tutorials
Connect me on Instagram i ll send tje circuit over there
And for gerber files i ll make a video on pcb designing with a free software so everyone can make therir designs by own

@@TEKNOISTIX bro I am on Instagram and following u. K.aol.733...pls upload the circuit
Here, voltage control and current control are dependent to eachother then why we are using two control knob instead one?
Sir computer ki power supply use kr skta hoon input main???
Yes
@@TEKNOISTIX thank you sir thanks a lot
Sorry i am not electrically good but question is i got lots of good and bad PC power supplies lying around. Is there any possibility to pull out massive transformer from there and use it for this project. Amperage and size wise are pretty beefy but not sure about Voltage. If someone can point me in right direction.
Ibll study about it and then i will be able to guide you
Can it be till 50 v what need to replace pls tell us
Meed to replace voltage regulator and rhe transformer
Clarification regarding 3055,in place of 3055,is it possible to incorporate mosfet,so that power dissipation can be reduced,any comments plz,thanks for upgrading the power supply
3055 in place of 3055?
Mosfet in place of 3055
3055 comes in mosfet pacage too
