Salutations. I’ve gone to school for electronic engineering, I’ve been a DIY tech hobbyist for many years, and I study these subjects virtually nonstop . But, somehow, Sorin you make things make better sense to me than any other professors, tutors, or texts can. Even concepts that I thought I understood well, I find myself learning about it something new. I enjoy watching, my friend. Thank you for being a fellow tech nerd with the ambition, time and generosity to share your knowledge with all interested on the Tube.😎👍🏼

hello sorin,yah it is easy to make,thats beacause you have a clear information about your project,i really love by making diy project.im just always waiting for your next video...keep up the good work sorin.

Awesome video, Sorin! I seriously love your soldering iron. Much respect.

whats fun in buying everything new when u can make it yourself keep up the good work love the vids

Great stuff Sorin... brings me back 30 years ago ;-) Respect !!! Greetings to lovely Romania!

Super lucrare. Imi place ce faci, explici clar fiecare lucru pe care îl faci. Good job !

Beautifully and professionally engineered and built!

Keep up the good work Sorin !!!

I'm in for the subscription! Again very informative, clear and funny, thanks again for sharing Sorin, great work 👍 👍

Nice design and construction, compact, and a reliable useful output, well done.. (Australia).

Very nicely done looks very professional. Thank you for uploading

Looks nice, I'd love to try building one my self

lovely build. truely diy. even the damn transformer is custom wound. Love ur channel :D Keep it up!!

Great video, and a smart looking PSU.

Nice equipment Sorin, congratulations !

great video,you do nice neat work,and you gave good advice regarding the V/A meter unfortunately I bought the two wire one not the good three wire one,but I learned something anyway.

Hey Sorin!! Long time No Chat!! This has a really good look for a really cheap price. I really like it!!!

love the project, keep it up bro!

Sweet build man, as for the cost argument, getting something custom built to the need can not be purchased, plus the learning experience is awesome. The other advantage to building is you now know how it works, so you can easily repair it.

Hi Sorin wellcome back , i love all your project . Imade one of your 18650 battery charger . it works very well ... tks Sorin

Cool video buddy! Nice build 👍

Nicely done

Nice build

I made a variable bench psu just yesterday, with the exact same dc-dc converter, however, I used a 90W laptop charger as the mains-to-dc conversion. Still a weird coincidence tho.

Very nice project!

Really nice job

Good job, bro 👍👍👍

Great video again. I particularly like some of the translations :) I'm not mocking as I cannot speak Romanian.

Nice work ♥️

Salut, @Sorin, imi place foarte mult canalul tau! :)

Interesting video, keep it up :)

Very Nice I love it

i have seen alot of these duy bench supplies but your presentation is the best because of the fact that you icluded the wiriing diagram ... just watching them do it without diagram can potentially burn out a component if you dont know whats happening .... thanks..alsoit was nice that you told me about the volt/amp meter destinction that one is good the other not so ...ill take the precaution when buying ty

Great video

Top work !!!

Nice Work Sorin ! I made a couple of them ! Switching power supply it's used in most electronics . Just if your working on microcontrollers based electronics a switching supply might give the designer a lot of headaches . Linear is the way to go ( if you can spear to dissipate some heat LMAo ! ) just modified one those 0 to 30 volt 0 to 3 amp DIY kit up to 0 to 25 amp . it was kinda fun . In the near future i'll post some of my own projects . Unfortunately they are not that entry level electronics . Anyway great to see peple from my own country doing this kinds of tutorials . Stay crative ! ;)

I like it. you deserve a subscribe

You should add smaller value potentiometer in series for better,more precise voltage set.Also adding 100nF paraller to big cap provide less hum in the output.

Can some one help me I’m trying to make a bench psu from a previous vid but I’m using a modern 650w psu. What dummy load resister should I stick on it. It’s has most of its power on 12v rail 648w @ 54amps 3.3v & 5v rails are 140w @ 25amps

@Sorin_DIY

hi. I don't think you can modify it, to get current limiting function. depending on the maximum voltage, you can use like me a step down converter with current limiter function and give the power supply another output.

Thank you for y?our video. This one was much better than your video on building a power supply from a PC power supply. Your English pronounciation has improved considerably. So I have subscribed now that I can understand you much better! Btw- The heat shrinking tubing is called eat Shrinkable TUBING. I am not certain what you are calling it but it doesn't appear to be right.

very good excellent projects engineer I have a doubt about the values ​​of the transformer you use for this project

Hi Flex type you have a product link

Can i reduce voltage drop if i use smps instead of transformer?. I'm using the same xl4016 converter.

@Sorin_DIY

4 жыл бұрын

you can't reduce the voltage drop. you can add a big capacitor in parallel with the step down converter input, 6300uF and 50V. it will keep the voltage more stable when you connect a big load, but only for 1-2 sec, not continuously. I think the only option is to use a more powerful power supply.

How to limit the current to a predefined value?

That was cool But thinking I would of added a couple more pots for fine voltage and current adjustment. But very nice nonetheless.

Excellent DIY! Thank you Sorin!

Cool video, please can you tell, how you connected the potentiometer with the amperage. I have having some problem with that, thanks.

@Sorin_DIY

your power supply is not complete. the 24V output it's the peak or the RMS voltage? did you connected the fan to the 24V output? have you connected a capacitor after the bridge rectifier? cooling fans usually need 12V maximum. the fan spins slower, because most of the power is used by the load.

Nice

What is the value of two resistors connected in parallel behind the capacitor and what is their use? If the voltage behind the capacitor is about 70V, how much resistor should I use? Please help, thank you.

The resistors are used to discharge the capacitors after the power supply is turned off. there isn't a fixed value, just enough to discharge the capacitors and not get hot in long use. you can use a 6.8Kohm and 2W resistor. If you use the power supply for a long time, you can check if the resistor is heating up, then you can use a more powerful resistor like 5W.

Now this is not a bad power supply. People just "hack" a computer power supply and call it a great power supply.

bonjour merci pour votre video pourriez vous me dire quelle transfo me faut il entre-sortie merci

hello, thanks for the tutorial, but I'd like to draw attention to the bugs. There is no description of the rectifier diode for powering the display in the drawing. Furthermore, resistance values (2W, or 5W?) Converter type Transformer values (2x12V, or 2X24V, or 1x24V, 1x 12V?) It would be good to add these data to the schema and description, especially for other handymen who want to build such a resource.
