Build the Ultimate Bench Power Supply for Electronics

like your videos but I don't speak English and like me thousands or millions of subscribers activate subtitles in the most common languages ​​including Spanish and you will earn money and subscribers thanks and congratulations

Nice work. Did you know about reusing old PC-power supplies for DIY lab power supplies?

Impressive... I was watching the video and saw when you serialized the 5v... I thought... that's going to cause a problem... I've done the same thing... but you came up with a very elegant solution!

may want to look at the power switch. you had an arc when you turned it on.

Great video
what is cost of making this bench power supply?

Great job! I built a similar power supply a while back and used almost the same components. You added a few things I hadn't thought of. Great job!

I want max amps on a 750w 34w on 12 volt rail

Peter parker😅😅

I thought the smoke from inside😅. Nice work 👏

Well done. I need one of those for my workbench. Nicely done good sir.

Great work. Of the 10 or so units Ive watched videos on, yours is by far the most functional! Keep it up!

Great build, thanks for sharing

Nice. Good Job. You look handsome too.... :)

so buy all new stuff except for the case, ????

Really great job and good tutorial!
Only thing I recommend is to avoid using hotglue at all cost. I used to do the same until I had a poor connection that over heated and the hotglue caught on fire. It burns surprisingly well. Instead, I'd much recommend going for conformal coating for proper isolation :)

this video reminds me of college days when we used to build fascinating things from scrap.

Great project! What type of apoxy do you use for holding the ports in place? Looking for a small batch apoxy for similar use cases.

Why would you use only a 5v max USB charge hub board, all phones and
tablets and much more use 9 or 12 or more voltage.

And why would you use a heat sensor for the fan, why not let the fan always
spin, and i mean spin low rpm, then the power supply board always stay cool
and you do not have to buy an solder extra stuff.

And why not use the holes to put the wires in and solder them, or better make
conrectors on it and slide it over the connectors with the hole in them?

Have done it myself, and works great.

Are the ampere adjustable?

So what's the polarity? Is it indicated in circuit diagram?

This is great but I think I’ll leave the cell charger out, I’m in the uk so I’ll see how mine goes with 240v 👀

mengumpulkan banyak module, menggabungkan nya dalam satu kemasan, terlihat seperti memaksakan banyak fitur dalam satu box yang kurang layak. dari biaya yang anda keluarkan untuk semua komponen tentunya anda sudah bisa membeli Bench Power Supply yang di rakit oleh pabrik dengan fitur yang sama bahkan lebih canggih, dan tentunya bentuk chasing yang bagus dan simple

Thanks

"I have a strong grasp of Arduino programming, although I haven't had the chance to gain practical experience due to financial constraints. I am seeking assistance to acquire the necessary funds to purchase an Arduino. Any support, even $0.1, would be greatly appreciated. I'm currently residing in Ethiopia, which adds difficulty to obtaining the required resources. Please respond if you can help. pleas reply for me, Thank you."

It would be way easier to use a pc psu case as a case, since it already has some of the ports for this project, other than that, awesome project!

Nice job and great post and wow you are patient with "so-called" experts lol

great. thanks

Great video Max! You are my biggest inspiration

Do yourself a favour and buy some grinding discs for that angle grinder of yours. Please stop using a cutting blade as a grinding blade. Thats how you will seriously injure yourself kid !!

You used very powerful power supply which can output 20A at 12V but you used 5A step down converter why?

I want a BOM and schematics, pretty please xo 🙂

using pencaps as spacers blew my fucking mind. i am not creative enough. ive been wanting to convert an old laptop to a linux desktop and those spacers have held me back. subbed

very useful and very well made!

Can someone please help me how to make the temperature sensor thingy, i cant figure out what diode or resistor the young lad is using

I planned on using an old psu from dell using potentiometers to inject low voltage.

süper(TÜRKEY)

I would like have had front and back panel 3d printed instead of wood. Awesome DIY

Holy Crap - I saw this unit in your RC Flying Wing video, and I was going to ask where you bought it. Excellent job ! It even looks like a retail product.

I appreciate the video but its crazy you didnt use a drill for all those screws. Great job, you're extremely intelligent.

I am extremely happy that I found this channel. This is a fantastic build guide video, and a great approach to a lab bench power supply. Good job on both the build and the production of this video 10/10

When I was in my teens 50 years ago, I built a vacuum tube radio transmitter with a chassis made from 46 oz. juice cans. This reminds me a lot of that. Nice job!

Gostei muito do projeto. Vou me inscrever no seu canal. Queria dar uma sugestão para proximo projeto.
Fazer uma estação de retrabalho.

I am looking to scavenge most of my components?>

Power Block for ATX ???

Warning !!
The LM7805 will be very hot when it use for charging the battery, better used buck converter module with PWM feature.

This inspired me to make my own power suply and so i made a small size power suply with the same buck converter ,2 18650 type li-ion chargers 1 charger for smaller drone batteries (a voltmeter that can be switch betwwen inputs to show the charging proggres of each battery) and a stable 12v,5v output each with its own voltmeter 3 usb ports 2 thermometers to show the temperature of the buck converter and the 220v ac to dc converter and a fan to cool everything The case is 3d printed and it is a beast. Thank you (ik the thermometers are probably overkil but i think it looks cool

Very good nice explanation power supply I am make power supply
