Affordable variable bench power supply - with external power source

Brilliant idea and turns out looking and functioning very good 👍 Thanks

Can you tell me the size of these box

Great Project as always!!
I wish you presented a little bit the module used, and remplacing the potentiometer for the current settings is not that helping. With those chinese module, the current setting is very sensible, a little turn of the knob and gone to much. Any idea to make it behave a little bit as the voltage potentiometer. Even with those blue multiturn turn pot is not that great.
You should make a video to present PSU modules, you got a great collection of PS and experiance with them, also teach how to set max current on them without load, and tips of course.
Thx

Hi any cuircit diagram

could you please do some projects or DIY using transformers from computer UPS ?.... I have seen many videos of spot welding using this.

Yeah, 60 bucks only for the multiturn pots...loooool

Sir please reply to my question❤ can I charge my 6000mah battery with 0.300 mili amps current? Is there any issue to charge battery with lower current?

does the buck converter make the output linear or is it still a switching power supply

🤪 Promo SM

....Very good sorin i am proud of you keep going bro....

can/could you make an 12v to 220v ups which charges its own battery ?

Jak zawsze piękna robota, skorzystam z projektu👍. Pozdrowienia i 1 l. mleka dla najlepszego pomocnika❤

Sir please make video on dual output ups 9v and 12v for router

How much current it can handle?

In my projects I usually need very low voltage and amps--below the minimum settings on PSUs. It would be nice to see a video on how to make a power supply capable of fine calibration in the 0.1V-1.5V range.

Good job as usual, nice result. Scratches to your cat! 😸

satisfying symmetry! I-Robot, or Wall-E? Good reuse of old laptop batteries. I think there is room to add some cells for a rechargeable system. Why Jaws?

I enjoyed your video, but you did not explain what a millimeter is.

I like your videos man. Keep pumping them up

Tip : Anybody who`s after an high current 12volts psu, Old xbox 360 power bricks output 12 volt at almost 16 amp and can be bought for under $10 as so many 360`s died from the red ring of dth, look for the older psu as the newer ones output less current, there are guides on how to wire them up on YT.

It would be nice if it has it's own power source for portability, especially if there's no power outlet available. nice video and thanks

Superb video as always. Cheap power supply made from easy to buy components

what an awesome and unique project, love it!

Salut Sorin, ai fost vrodata in Thassos in vacanza?

Awesome Sorin, thank you for sharing your projects with us 😊

Sometimes it is handy to measure the voltage at the load instead of at the power supply output terminal. Simply put binding posts on the voltmeter leads and use an external jumper to connect to the power output terminals most of the time, and remove that jumper and use leads when you want to measure the voltage at the load.

Great video! I would add a fan to the step up converter and I would also put thermal paste on its transistors because sometimes it doesn't even come with it.

Are u Russian moi tovarish Sorin ?

That electric box has a nice feature, in the compartment on top, you can store some cables with banana jacks.

If wires, or any other parts are missing.....check the cat....

well brother ill see you in the next one keep on keepin on

yeah i could build one of these and i have all the things i need to build this but i dont have a case or potentionometers and i dont have money and never will so its sitting on the back burner until i get a job or money one day lol but yeah thanks for making this video so i know how to hook everything up wright lol man ive been wanting to make one of these for like 8 years now dang it lol

lol yeah i have one of these and i want to turn it into one of these power supplies but im poor and cant afford the potentionmeters lol or the case lol but what ever i bought this power supply years ago lol i hate being poor

How much power supplies does he own?

nice one :)

perfect :) thanks

No cat, no project!!!

If I was going to build a similar one, I would need to source another volt/amp meter. All that type, I've purchased in the past have absolutely terrible accuracy. Some can't even adjust to within 0.5V/0.5A, as the potentiometers reach their stops. Zero faith, in that type, Sorin.

Please put the Arabic translation so we can benefit from the video. Thank you."

How many DIY power supplies do you want?

Sorin: Yes

At this point Sorin owns every Modules from amazon or PSU or VPS

I used an old canon printer psu as a variable power supply for my projects. Can go as low as 4.6 volts to 25 volts with a max amp value of i think 3amps before overcurrent protection kicks in. I only took the sensing transistor out and replaced it with a 100k potentiometer so i can manually adjust the voltage, worked really well.

Im planning to transfer it to a better case, more specific, a computer psu. And i recently got another epson printer psu that has 45v 3a max output. Recently tested it amd it gene fron 2.2 volts to ofcourse 45v, way better minimum value than my canon printer. Might put two of em tgether as separate outputs in a single case.

stupid question here, what will you use it for?

I am using old computer power supply as a case for my DIY bench supply 🙂 It has more advantages

Yuhuuu

Thanks for the nice box recommendation

Nice power supply. And by the way, the cat's very cute 😍.

Very good

Now bro is owning the whole industry of variable power supply 😂
