For all of you asking "WTH is that resistor on the 5V doing there?": For the PSU to correctly regulate the +5V output voltage it needs to have some sort of load attached, at least 5W to trick the PSU into thinking its attached to the motherboard.

[@JamesGravesJr]

If I were to do this project, I'd likely try using a 5W LED light, on a flexible stalk.

[@WarrenPostma]

@@JamesGravesJr Great idea! Often when we are working we need a task light to focus on some thing we are doing.

[@mashedpotatoes5323]

Some power supplies don't need any resistors on the outputs. I used to buy and sell computers so I have quite a few spare PSU's and some of them seem to work just fine by shorting the green sense wire to ground to get it to turn on, as other PSU's will need a load on the output to turn on.

I made a less refined one of these years ago. It did it’s job and served it purpose until I pushed it beyond its capabilities. This video has inspired me to make a new one. I have a lightly used 1400w modular Corsair PSU sitting in my graveyard. I think it’s time to see what I can do with it.

Thanks, I like the variable addition. FYI, rather than an expensive 10 ohm power resistor, I use an old 12v 1157 taillight. The 5V lights up the inside of the box with a glow to tell you it's ON.

Is the 5v from the power supply going to high or low beam on the bulb?

What is the function of the power resistor? can it be replaced or is that expensive resistor optional?

[@miguelcalderon3702]

@@diegof.8052 Some power supplies do not turn on unless there is a load on it. Basically the resistor makes the power supply think its connected to a motherboard so it can supply power.

[@diegof.8052]

@@miguelcalderon3702 Thanks for the clarification. The power resistor used in the video is expensive, do you think the resistor you see here amzn.to/3lw9rGO can work? By the way, to date Daniele Tartaglia has not yet uploaded the schematic electric or the list of materials he used. 😒

[@miguelcalderon3702]

@@diegof.8052 well every power supply is different so one might need a 10 watt resistor, others 12 watt and so on. But yes those resistors should work just fine just make sure you have some kind of cooling in the housing like a fan or something to keep the resistor and components cool. And to turn the supply on just need to ground the green wire(you can can connect a switch between both wires so it only cuts on when you press the switch. And for a 12v power supply connect a 3-4 black wires to a black banana plug(-), and 3-4 yellow wires(+) to another plug and you should get 12 volts and the same thing applies for the rest of the colors on the supply. Just make sure you know the output power of the wire colors on the power supply. And careful when testing inside the power supply because they can produce alot of amps and that can really mess you up.

[@BrunodeSouzaLino]

One way you can discharge the caps without attaching stuff to them (which could cause those large value caps to blow up if you exceed what they can take) is unplugging the supply off the outlet and keeping the power switch pressed for about a minute.

[@roygalaasen]

I think I would discharge them safely using resistors to be on the safe side. My first thought when he opened the box was, yikes! That is going to burn some hands. Never assume they are discharged just because they have been standing on some shelf for years. I once had a look into a DVD player that was struck by lightning to see if I was bothered to try to fix it. My thumb came across one of the capacitors, and in a second I got an entry and exit burn on my thumb. That for a device that had been unplugged on a shelf for a full year. Be careful, and know what you are doing before opening up. Those things are so easy to overlook, and you get no warning signs at all.

[@jaaps772]

Watching this video gets me in a tranquility flow.

[@sincerelyyours7538]

The Good: The front panel artwork is awesome. I especially like the method used as I'd not seen that before. The Bad: As usual with these DIY supplies, there is no way to adjust Constant Current which means that the supply will feed its maximum current at whatever voltage it is set for into the load whenever a short circuit is encountered. Since these ATX supplies can deliver 25 amps or more, that can be very dangerous, both to the operator and to the circuit under test. It's a very useful troubleshooting technique to be able to dial down the current so that when power is applied, the current is limited to a level that is safe for the circuit. This is also especially useful for charging Li-ion batteries as you want to both limit the current and taper it off as the battery reaches its maximum voltage, otherwise it could blow up in a spectacular fireball. Don't ask me how I know this. Also, why mount the power resistor on the outside? It'll just bang into things and possibly scratch them up.

[@stspringer2003]

How would you incorporate "dial down the current" in this build? Thanks

So most supplies you find on the tubes use 3v, 5v and 12v wires, each with it's own terminals. This uses only the 12v for usage and uses the step up step down to adjust to what you want, which also adjust the current (amps). I like it.

[@Daunlouded]

I would have mounted the dummy load inside on the "front cover" part near the fan for increased cooling and is out of sight. Other than that it's pretty good. Also some rubber pads (from old laptops) would keep the PSU from sliding on the table.

Another thing you can do with an old ATX power supply is use it to power LED light strips. You can light every room in your house off a single power supply. I bought a strip of lights an arduino and salvaged an old power supply, a pvc pipe and some old vinyl gutter to make programmable fish tank lights for under 40 bucks. Not only do I have light for the fish tank that had I bought in town would have cost at least twice as much, but I can program it to shut off at a specific time, adjust not only color and over all light level but individually light sections of the tank if I want. I can have a morning program and an evening program, or whatever I want. If you can't program an arduino, then just buy a premade LED controller that wifi links to your phone. Not as versatile but way easier to setup. I have even managed to mix in colors along with the white light to make the decoration colors pop more and even make the fish appear more vibrant. the strip burns out after a few years of use, but so do normal light bulbs and at a replacement cost of 14 dollars it's not a big deal. Because most LED fish tank lights have to be replaced when they burn out.

[@terryboyle]

Thought there would be a dedicated USB plug from the early on-screen comments

[@therealjammit]

I'm certain I saw some leaking electrolytics in the ATX power supply. Good idea. I was thinking of rewinding the transformer and feedback on one for a single output, variable voltage (9 to 15 volts) power supply. Much easier to leave the other voltages intact and add an adjustable boost/buck converter to the 12 volt rail. I'd also add a few extra grounds.

because old atx power units needs to have some load on 5v line to supply current on 12v line; if you don't load the 5v, the 12v is very poor; it's just a design feature and not a fault. But some other rather new power units don't need that... just try put your unit's 12v under load and check voltage.

[@bgable7707]

what potentiometers did you use and from where thanks.

[@androndeau]

Quelqu'un a-t-il trouvé la valeur des 3 potentiomètres ? Et quelle est le voltage de la led témoin d'alimentation ?

[@arduinopcduino6441]

@@androndeau En fait, a 6m28, il y a une image du potar, c'est 220 KOhm. Pour la LED, il utilise le fil gris des alim ATX qui correspond à "Alim OK" , donc un 12V quand l'alim est OK après c'est dommage de ne pas fournir un schéma de câblage quand on voit le travail éffectué...

Oui on voit un potentiomètre de 220k mais les 2 autres ne sont pas les mêmes. Il faut croire que personnes n'arrivent à avoir les valeurs de ces potentiomètres lol

Good video, sadly it would cost more to buy parts where i live than to buy a desktop supply off aliexpress. Also from my experience if you draw high amps through even 12v wires for extended periods they will melt (considering most people bind together for better amperage) simple fix better wire. I love tinkering but you soon learn why youtube etc can be bad as most don't actually show/teach you the dangers of what happens if you F*k something up. Keep it up

[@김수한-o2z1u]

How is the voltage control and wiring method is the same when connecting other bolt meter than boltmeter shown in the video?

[@guilhermetorresj]

It surely depends on what "voltmeter" you want to use. The one he used had a diagram on its sticker for the connections. The control method he used was simply replacing the trimpots of the converter for regular potentiometers and sticking the knobs through the ATX PSU's metal cover for easy access.

[@CapnSlipp]

Man, boltmeters exist? I’ve got all these left over screws and bolts and I’m not sure what will go with what. Had I know I could just get a boltmeter, I’d have just done that ages ago!

Eres increíblemente creativo , me encanta tu canal y hacer tus proyectos

[@CezarVideoBlog]

hey dude, why shall i replace a good 10 turn trimer, with a one turn potentiometer? you can always use a 10 turn, panel mounted. not a good advice at all. I have to say, that adjusting a trim-pot with a fancy screwdriver make it professional... :) lol just i cant watch until the end, please fix the boards at list in 2 points, and never share the same heat dispenser radiator, of devices that do not use the same rail on the radiator (the heatsink - the heat is not sinking it is radiated on the ambient), is a hazard, and a disaster waiting to happen... totally unsafe, unprofessional ... not good, sorry just being honest.

[@douglasgrey5802]

I'm sorry, but I too am at odds with your comments. I read it several times to get the context of it... Firstly you totally missed the "fancy screwdriver" part. If you like wasting your time making that many turns to achieve your output, then go right ahead. As to your analogy of the "radiator"... you totally lost me there. I took " radiator" to mean heat sink? If that's the case, then you are way off base. Your reference to "fix the boards at list in 2 points"... haven't a clue to what your talking about, "sorry just being honest" here.

[@CezarVideoBlog]

@@douglasgrey5802 Hey mate, Can you please explain how i am way off ? Regarding the fancy screwdriver, yes, you need to turn it many times to adjust the voltage, in smooth steps, using a power-tool to turn a fine adjustment trimmer is just strange and unnecessary, not wrong in any way :) Regarding the danger, have you measured the voltage on that RADIATOR ( heatsink ) and ground plane ? is the voltage safe? is it DC OR AC? The regulator board is fixed to the Radiator(. heatsink for you) on one hole, ( kzbin.info/www/bejne/oWK2pYuBjLmhrNE) , the only thing that has to stay on a heatsink is the part(s) that need to be cooled. Please do not be naive, high voltage is dangerous, mains voltage is dangerous, and can kill. The reason the board come with 4 holes in the corners, is because it is looking proportional, and not for safe fixing the board. The Radiator can be at elevated potential, relative to ground. ( what happen when the heatsink melt the plastic spacer? In a nutshell, I consider that the advice given herein the video is wrong, and unsafe. Please do not do this at home, take it apart, make a nice enclosure to house the boards and needed stuff, is safer. The RADIATOR : The passive heatsink is called a RADIATOR because it using convection to dissipate the heat, so it radiate the heat, in to the environment, in this case the air, natural convection of forced by a fan, it is still a radiator, it is also called a heatsink, none of the terms are wrong.

the link to download and project part opens so much unwanted ads it's really very wrong that u said there is no virus, but what about the ads it's such a kind of virus only. and u did so much promotions in the description your description is full of other stuff in place of the main video content😒, u r just doing more n more advertisement don't fool people with more others stuffs first of all do the main video and their content understandable and easy to access. If you hurt then I'm sorry, i just trying to make u aware of it because most of the people don't like this. Hope u understand what I am trying to say.

Wouldn't recommend drilling a hole through a PCB, it could be a multi layer PCB with traces in the middle layer.

[@plug4uk696]

Biggest load of bollox I've seen!! You would never drill through a circuit board like that then to mount it on a large heat-sink using a self-taping screw screwing it down so the components short circuit on the underside. No insulated material was used to protect that circuit! Bit daft mounting that power resistor on the outside when it could have been mounted in the exact same spot on the inside directly in line with the fan blowing on it to cool it down more efficiently...

@plug4uk it certainly looks risky, but if there is only one copper layer in that board then it should be more or less safe, as he drilled through solid epoxy rather than any electrical connection. He's demonstrating that its possible to make more space for stuff if you are willing to be a bit unconventional. @jeremy Well people might get the wrong idea when they see this video, but unless you are into electronics and are comfortable working with 240V you should stay far away from a project like this.
