You should add a high power dummy load on the power rail (in this case red 5V) to keep the power supply a little bit more stable for low amounts of current I forgot to mention that

Dont do it like that The soldering an mechanical quality of this build is bad as hell ^^

Watch those displays I did this project and tried the wiring I created a short, which my power supply thankfully recognized and shut off immediately I also accidentally swapped voltage polarity and immediately lit my wires on fire So do be careful If your display has a yellow wire instead of a blue one, look up a tutorial on how to wire those; they give good guidance on interesting wiring conventions I've only got the hardest part left: making the chassis look decent Good video

Love how it's impossible to separate "DIY variable power supply" from "I took a PC power box and put some banana plugs on it", thanks, clickbait culture :))))))
Comment from : Bobo

I know that i am really late but i wanted to ask if i wanted finer control for the voltage how could i do that? Could i just add a second pontentimeter of higher resistance value to the original one?

Is the buck boost module still works pls pls tell
Comment from : LL Lasantha

Is it xl4016 based buck converter ?
Comment from : Amit Ghosh

how many amps?
Comment from : Albin

Just buy the kit don't be cheap
Comment from : GlareTV

No link for stuff that you use?
Comment from : Jay Montano

Somehow I don't think less than $10 works, since the power supply itself is $20
Comment from : James Stephens

The only issue I have with SMPS is the fact that you can't really do anything with an oscilloscope unless you use an isolation transformer I built my power supply with a linear transformer I just used an MOT rewound to 24v

This bench power suply can be limit voltage

great vid!

I got the DSW5020, the 20 amp version Worked for awhile Suddenly I can no longer test my laser diodescan't get more than 125 amps out of it even when I set the max amps to 5 Really strange I tried changing the power source but that did not help either No longer works
Comment from : Andrew Baer, MD

Can I solder a normal 100 kOhm resistor to a 100 kOhm multiturn potentiometer in order to get to 200 kOhm? Can't find a 200 kOhm multiturn potentiometer! My step up booster uses the 204w trimmpot

Great video I think this will be my first electronics project

1:29 There is a story about Made in PRC
Comment from : B T

So the regulator can go up to 3Amps, but the power supply can go up to 30amps Did you use the 30Amps output or not? Did you use only the 12V output?
Comment from : sotospt52

A couple of questions Why solder multiple 12v cables to the input of the converter? Why not just one 12v cable? Is it just for redundancy? Also, would you pick the the highest voltage output from the pc power supply or would it be better to pick the highest amp output on the pc supply Last question, what is the middle potentiometer on the buck boost used for ? if the other two are used for voltage and ampage adjustment If anyone could help me with this It would be much appreciated!
Comment from : Daniel Baker

The link for buck-boost converter doesn't work, is there any alternative for that ?

Nice video nice information about the price it’s over $20 I don’t know how you came up with $10 approximately but it’s nice thank you
Comment from : Eli Dari

TKS for sharing your knowledge So if I want to put more Ampers I have to use another device, I would like to put 13,8V with 20 Ampers is that possible? TKS

A or B pots are you used?
Comment from : Vata’s lab

Nice power supply, but less than 10$ if you have most of the components
Comment from : Daniel Carrasco Marín

Well, < $10 considering reused power supply, and excluding shipping cost, is those included, it brings up to $40so keep that in mind everyone
Comment from : Raagam Parmar

Great video! Thanks! One thing though, is the links to the parts you have are mostly gone now The listing has ended, or there sold out, or just gone for good Do you mind updating that page?
Comment from : -canCode-

what the hell is under 10$ Either you are a liar, or you forgot to mention you maybe paid 10$ of your own money and the rest comes from sponsors
Comment from : Little Bastard

Great explanation, and your website and links are great!
Comment from : Capn Ridiculous Witts

$10???? The meter alone is half of that

Great project Last week I found working ATX power supply on the street and I want to make an adjustable power supply Your tutorial is the best one I have found :D thank you very much! Amazing work!
Comment from : Maro

I have question if I apply 12 5a at the input of the buck converter what is the output voltage and current

which software you are use for design schematic diagram? pls tell me
Comment from : AH SABUJ

Hi, I have a voltmeter ammeter with yellow black and red wires and black and red, if I connect the way you in diagram it shorts and shuts psu,can you tell how should I connect correctly to make it work for variable output?
Comment from : M B

Bro maximum out put current and voltage rating of this variable lab bench power
Comment from : Anshuman Mohanty

Your videos are very informative but I am confused on some basics For example, only one power source is used, so why not use just one black banana plug for all the dedicated voltage plugs? This would tie in with the common ground copper-bus suggested below--or have I overlooked something?
Comment from : Denzil Cypret

I would like to have AC not only DC, do you have any suggestions?
Comment from : Donald M

Just what I've been looking for! However, I am a noob and a little confused Does the output enable switch in the schematic have to be 'ON' to get variable output from the buck-boost converter? Also, will the LCD function when that switch is 'OFF'? I know, very stupid questions that are covered by the video but my infant brain won't recognize them! Many thanks!

Can we use step down buck converter
Comment from : Minakshi Minu

Hi please give me some advice I have a computer power supply that is rated at 350W I want to put a pair of USB plugs onto it to utalize the 33v 20A, 5v x 20A, 5v x 2A, and the 2 x 12v x 312W outputsbrMy plan is to do 2 x 5v USB, 1 x 33v 1 x 12 v to power a T12 soldering iron and the other a 12v a buck buck boosted supply What would you recommended?

Great vid! Thanks!
Comment from : Shawn Brown

Thank you for a great, helpful and informative video It is a shame small minded people make such a fuss about your less than $10 title and completely miss the useful information We should all be encouraged by your resourcefulness to reuse scrape and old material for our DIY projects

Is your schematic correct for the voltmeter module? My units have a yellow sense wire diyprojectseu/how-to-wire-digital-dual-display-volt-and-ammeter/brAlso, I use the 5V standby voltage from the ATX PSU - this means the meter is lit when the ATX has mains power but shows 0V and 0A When ATX output is switched on, Voltage is displayed

hi how are you? can i know how to make the labels that you are using on your project ?brthanks
Comment from : Markjastine

If I'm using a 300w ATX is it possible to get 12v 300w or 24v 300w?brI work with LEDs and need the powerbrWhy did you put the variable resistors the other way around to the display markings?
Comment from : LEO

Heu bro I want to buy a step-up and a step-down converter They should output the same voltage ranges?brThe step-down converter output from 13 to 35 Volts and the step-up converter from 5-24volts

Sad that you ruined the printed cover with carelessness Needle nose pliers would prevent all the scratches
Comment from : rm709

Great video, I got an issue, using a different model lcd, looks the same but its a bit different wiring, dsn-vc288, the problem I have is that I can only seem to see volts or amps not at the same time, i have to remove the thick red wire (amps) and connect the (thin) yellow wire (volts) but cant connect them both

Less than $10 click bait bullsht
Comment from : Xavier

I don't understand if you're voltage converter can only handle 3:00 amps how do you have all the buttons for or is that not part of the variable part

Led module Positive and negative is connect each other by that steel bar, Did you un-connect them?
Comment from : Aimless

I used this buck boost module with a 12v 5a smps but after connecting and switching on the supply I saw a crack on LM2596 ic but it haven't come out of the pcb I didn't connect anything in reverse I don't know what went wrong plz help
Comment from : Allone

What if we use bigger potentiometer with different value?
Comment from : Amateur Inventor

Hm I need a power supply But I have a PC power supply left over And I have two voltage regulators left over from another projectbrNot sure if I can get current limitations though
Comment from : Lennart Regebro

My ocd is kicking in your display have Tension on Top and Current on Bottom, and you don't put in same order for the potentiometters ? ^^

Comment from : Chicken McFly

Great video! Questions: If you were making a bench power supply like this with a transformer instead of an ATX, and a 3-in-1 Adjustable DC Regulated Power Supply DIY Kit, how could you get 33, 5, and 12 volts for the fixed voltage outputs?
Comment from : Thomas B

Thankew for such wonderful DIY My SMPS is from 2000 as well however my capacitors near the AC supply end were burned , they are 200v 330uf I tried to search for these online but found none If you had faced this I wonder huv did you find these capacitors
