Finally, finally, a video that actually teaches something, no noisy background music, no video only type instruction, no heavy accent, no fast talking and excellent camera angles, along with excellent diagrams and presentation. Yes, I wish I had you as my high school electronics teacher. Maybe I would of attended more classes and actually learned something. Keep up the great videos.
I am 72 years of age, and I so wish you had been a teacher at my school way back in the 1960's. Every aspect of your youtube vid is 100% perfect, no music, clarity of annunciation is great, presentation cannot be faulted, even at my age I am still learning thanks to you. Please dont' stop. Thank you.
It's amazing how so many of us want these type of videos yet so few produce them even though we almost always voice our opinions on the unwanted music and editing of the majority of poor quality videos. Keep up what you are doing because you are one of the few that actually care what us the viewer actually want to see and learn from.
Hi Bill, You have one of the most listening-friendly, patient, relaxed and slow tutorial voices I've heard. I thoroughly enjoyed this tutorial and your easy-to-follow instructions. Well done and thanks.
Brilliant! No wobble cam, no annoying music. Well scripted, well lit and well presented. Thank you! The ATX PSU that I "rescued" from a long since redundant PC now has a new purpose in life. Keep up the excellent work.
I avoided this video initially due to the length of the video. Having wasted a lot of time elsewhere I came back to watch this one. I now feel comfortable, safe and confident to proceed with this project. Clear, concise and intelligible comments and well shot video with good circuit diagrams. Thank you.
Very useful, thanks Bill. A local computer repair shop here in Ontario gave me two older (but functional) ATX power supplies for free. I used these to make to PID controlled heating devices, one for heat bending guitar parts, and one for a 3d printer filament dryer. Of course, I used the guidance in this video for the builds.
You are a calm, decent and respectful man. The explanation is clear and most importantly there is no background music. Thank you very much. My only objection is to adding a resistor , as it constitutes an unnecessary load to the circuit, especially since it is connected in parallel.
OUTSTANDING! I have been waiting for you to do this video.. I have watch others do this but most of them are fly by the seat of your pants young fellas.. I wanted to make one for my new hobby (at 66 I am teaching myself something new!!) I like to see others ideas but only follow those men I think know what they are doing. And you are one of those men.. I really thank you for all of your hard work in making these little videos (it really shows) thay have been an immense help to me.. as I am a little slower then I was when I was a younger man.. But I an not through yet... Carry on your teaching is very much appreciated..
@tinkmarshino... My story precisely! Cardiologist by day, projects on weekends at 66!! Thank you for such well-done clear instructions for the project!
Your way of explaining everything is second to no one's. I would love to have your calm demeanor. I've learned so much from you are a semi-newbie to electronics. Well done Bill!
Very nice video, well-explained and thorough. I do have a minor quibble, however. The ATX spec defines the PSO function as edge-triggered, rather than level-triggered. In other words, you do not have to lift PSO to +5V and keep it there - simply pulsing it to +5V will turn on the supply. The spec actually recommends a momentary switch for this function, rather than an SPST as you have used here. Turning off the supply is a matter of holding the momentary switch down for 4 seconds. So one brief pulse to turn on, 4 seconds to turn off. I have not seen any damage to PSO circuits as a result of continuous application of +5V, just saying it's not part of the spec. Personally, I use the ignition switch from a 1974 Chevy Vega (the only part of the car worth keeping) mounted on the side of my case to do the start-up. So far, the PC has not leaked any oil, which confuses a Vega key.
This video is a very useful tutorial. I actually did this and converted an old computer power supply into a bench power supply in a single day at almost no cost from this video. Keep up the great work!
Wow! Am I lucky to have just found this channel. The standards of construction and presentation are stellar! The dialogue is clear and even though I have been into electronics for decades, I am still learning.
The wiring diagram starting at 20:22 is the first of its type that I have seen on a site like this, and it makes all the difference in the world. A simple schematic like the one you use makes duplication a far simpler task than trying to remember all the connections made over 15 minutes of video. Genius. Added comment: Posted the above before seeing the end of the video. A visit to the web site is even more inspiring. Step-by-step with downloadable pdf? Doesn't get any better than this. Thanks again!
Thank you for another great video! I have built a similar bench power supply from an old ATX I had about a year ago. It has proven extremely useful and was quite easy to make. If you are at all interested in electronics, just do it! It's easier than you think, just be safe. Also, I would suggest adding a USB port to the 5V line, as a power outlet for USB connected devices (Arduinos, for example). It makes the bench a bit more useful.
I'm not sure but ,if anyone else is searching for electronic circuit board repairs try Saankramer Electronic Magazine System (should be on google have a look ) ? Ive heard some pretty good things about it and my work buddy got amazing success with it.
Hi, from South Africa, I do enjoy your presentation on all things electronic, I am a 73 year old retired Elec-Eng and I lecture for 10 weeks, once a week, August to November, at a "CAD" College. The students I lecture Mechanical and Architectural students and we do Electrical Design using AutoCAD and SolidWorks Electrical CAD. I have a few "breadboard" exercises for the students and I think your "ATX" power supply/bench supply is just the thing for these exercises. I will be visiting the computer-scrap-joints to ferret out a few ATX's units before August this year. thanks
Some newer power supplies have several "rails" to separate the load. If you want to pass through a lot of current, you should probably consider which wires you use, and not just pick the ones on the motherboard plug. Also, if you don't want to open the power supply, there's no stopping you from simply leaving things unconnected. Some power supplies also have modular connectors, which makes it even easier to pick the ones you want. In any case, these things are so easy to find. Nice video, showing how easy it is to use.
Fantastic presentation.....this is so user friendly especially for those that are relatively new to anything electronics. I like the coloured voltage levels etc and the wire paths with the visual presentation of the inputs and where they go to......even my long deceased granny could follow this plan and she was into crystal sets in the 20's.
Very clear & simple wiring video with many cautions included. Gives very safety assurance in wiring-up step by step. TQ especially on the part on volt-amp meter wiring caution. Pl continue your generous effective teachings
Hello,i am retired and live in the Netherlands,i was looking for info for arduino ,and i came here on this channel,and this is what i need.No irritating music is fun to see the video,s on the channel.So keep going on ,on this way. Thanks mwrv1,
Thank you. I really appreciate the step-by-step, easy to understand, and well illustrated presentation of your videos. As a beginner in the world of electronics, It makes it incredibly easy to get started. I literally harvested an old power supply last week and was wondering how I could do this.. and like magic one of your videos popped up.
I would have to say this is one of the best tutorial video’s I’ve seen on RUclips yet. Great video, easy to follow and very informational. Fantastic job.
I'm so glad I stumbled upon your videos. I graduated with a CS major, only taking a few digital electronics and ECE courses in my time at school so I am expanding outwards in that field and I was looking for a way to utilize parts that I already have. You have made my night.
Junked an old computer recently for the gold and was not only looking for ways to reuse the other bits, but have needed a bench-top 12v power supply for a long time. This is *exactly* the video I was looking for. Thank you!
Thank You, you explained everything in a very detailed and simple way. My knowledge of English language is weak, but spite of this I understood everything. You are perfect teacher.
In the midst of building this with a 3D printed case, thank you very much for a comprehensive and detailed overview, so helpful and useful in planning our project !!
@@als1023 Sorry, I didn't look to see how old your post was... duhhh! Anyway, glad it went well. I've a mind to use up an old ATX supply this way but I'll have to content myself with making the case from plywood.
Amazing video! Thank you so much. Looking at this power supply and thinking of how to turn it into a bench supply felt like a daunting process. Within 10 minutes of absorbing your knowledge, I feel confident. Very nicely thought out and explained.
Yep. I enjoyed it very much! Never thought I'd watch an ATX bench power supply video from start to finish, while being fascinated. This was professional and good quality.
Amazing. I was literally taking a break from building the same style PS. I was researching the different 5V lines. Thank you so much for your informative videos. Now I will add the volt/amp meter. I enjoy your videos so much.
For the first time in my life I understood what all these wires do. Other videos just rush through this topic. Thank you so much for making this video. 👍
Thank you so much for this informative video! I'm in need of a bench power supply, but am on (disability) a low budget. I do have a few desktop power supplies laying around so this will help me immensely.
You're a great instructor, very well done. One correction about the 4 pin 12v connector, It's was made to provide good clean direct power to the CPU itself, not its fan.
Excellent video, covering all aspects. Awesome narration and very attractive voice with beautiful pronunciation & punctuation. One of the best diy video I've seen after great scott.
I built one of these years ago and it was very useful. Instead of the load resistor on the 5V line, I attached an old style, filament light bulb. I mounted it on the PSU box and it helped inspect circuit boards at times. I also added a custom 0V dock on the box for my multimeter - one wire frequently needs to be grounded.
This is fantastic. I took electrical training and the master test. I later took computer classes that included building a computer from scratch. Now if your video had been included with any of my classes. I would have had a better understanding of why the connections were as they were. Instead of plug in play and pray. Thanks for this incredible video.
This rocked as all of your videos do. I found your channel when I got into Arduino and I am hooked. Please keep up the great work! Subscribed! I created and 3D printed the control panel. I'll post the files on thingaverse and add a link soon.
Splendid presentation! Excellent illustrations, articulation, and explanations. Last night I took apart an old PC to destroy the HDUs. I saved the power supply with in mind to use it as a bench supply. Came here to find out how and hit gold.
Hey All. I built this and it rocks! My power supply can give me 5V at 25A, way more then a $200 supply I saw on the net. The only issue was getting that 50W 8RJ resistor. I had to wait 2 weeks for it and now Amazon's not getting any more in. I also 3D printed the control panel and it looks cool. If you're messing around with those WS2812B LED Strips, or motors, you're going to need a lot of power (amps). Thank you for an awesome video.
Greetings from Australia, thank you so much for the detailed project, a true gentleman and genius , well explained and excellent show , especially adding the current /voltage display unit, excellent and back - to - basics switching approach , thanks for sharing , can’t wait to make this project, I’ve subscribed, and definitely 200% thumbs up, champion!
Bravo! You speak low and slow enough for me to follow you. You are, in essence, the Mr. Rogers of the electronics workshop. You make it easy for me to repair the Commodore Amiga's that pass to close my way by your creative prowess. :)
I agree for what you talking about it is well explained, I can relate to convert ATX variables power supply into personal projects, it’s very handy to run those 3 voltages specially in electronics as required, conversions, modifications is an interesting hobbies as long as you know what you doing, it’s a pleasure to achieve something like that specially for testing, very good on you, just keep it up peoples thoroughly learnings how to educate them through your knowledge regardless, Bless you
Hi Bill. Thank you so much for your detailed and easy to follow instructions. I've been looking for awhile for a tutorial on making my own Work Bench pc power supply. I am 76 years of age. I started in my teens and here I am still learning. I will be subscribing and following your channel from now on. Blessings
Thank you very much for your interesting and helpful videos❗️You explain every detail so clear that everyone can understand what you are doing. For me as a hobby electronic your selfmade easy projects are so good. Hope you go on... Regards, Boris🇨🇭
Got a spare PSU, been wondering how to convert it into a power supply for my Electronics Projects, Thank you awesome video good explanation and I have one of those meters that I've never used too, job done, just waiting for the parts.
Thank you for the excellent in-depth tutorial. Your method of wiring of the meter has yet an added advantage. I wired one into a similarly designed circuit, but used the output to supply power to the meter. An inductive spike from a load that I disconnected under power damaged the meter. I was able to troubleshoot and repair it, but had I used your technique, it would have been isolated from the load. In my case, I used a small “wall wart” to supply the meter.
I built this on to a black perspex panel (which I will box up properly later), and put a little voltmeter on each rail, (plus fused each rail). I added the V/A meter circuit too, so that I can feed a dedicated circuit when I am messing about with the little kits, and monitor things. The sense wires I have run out separately, so that I can use them as required. Many thanks for putting this up, it was extremely helpful!!
Hi man, great video! I love how clear you are explaining everything on your channel. Thanks. I have a question. I made my ATX bench, and all the outputs are ok, but with a slight instability in tension, like +/- 0.02 volts, and when I want to use it to power my servomotors (controlled by Arduino), this slight instability makes my servos jitter very hard. Do you know what can be de cause and/or solution to this? Thanks in advance everyone!
This is absolutely the best electronic teacher and course, display I have ever seen. During this covid 19 crisis I seem to have time on my hands and this project really fits into my plans as I often need to check amp draw on automotive fans, pumps and stuff.
Excellent vid ! I'm looking at adding a bench power supply to my shop, and was wondering if one of these would make a good solution to meet that need . The clear well-measured narration was a GREAT help in following along with what you had in mind. All the BEST - and thanks again for a great vid ! - C.
Now that is a very beginner friendly video. Well Done! Only one hickup and i think it's major: 23:18 Don't crimp and solder! You solder low current lines and you crimp high current lines. This is because high currents will heat up the wires and might eventually melt the solder. When the solder melts, it leaves gaps between all the tiny copper threads the wires are made of, thus massively reducing the area of contact between the wire and the lug. Now all the current has to go through these smaller areas of contact, heating the thing up even more. If you are lucky it does not start to burn, if you are not, it does! And that's why you shouldn't mix crimping and soldering!
from 28:07 ...........There is a distinct difference in the usage here of the term ------Ground ----- This is actually the minus (- ) ..negative rail. and not to be confused to Ground of the Mains. !!!
Totally agree... The word GROUND should only be used to mean Earth/Ground. The green wire in your mains socket, the one coming in through the AC cord. That green wire is usually connected to the metal case of the power supply unit. It is NOT the same as the black wires! They call it the "0V" rail, as in zero volts. The 0V rail provides a reference point from which the other rails can be measured; that includes the negative voltages.)
I liked the how you use wood to place all those components instead of taking the hard way drilling holes on the power supply itself making life a living hell of doing it without proper tools. But the wood is soft and easy ...i never thought of that..you are da the best
Great use for an old ATX power supply! Following your directions in this video I cooked up one for myself, with one variation- I located the large heatsink encased resistor inside the ATX's case out of the way of anything and in the airflow of the fan. With it attached to the metal case, it doesn't put out much heat, but... I also reused a metal enclosure from an old car battery charger, and everything fit perfectly! I cut the back of the enclosure to expose the rear of the ATX so I could get to the switch and power cord connector, and buttoned it up neatly. Thank you for the share and keep 'em coming! I'm subscribed!
This was a really good explanation and walk through and I wish I had seen this years ago when I first modified one of my spare supplies. It took me far too long to get everything figured out but I managed it and didn't die in the process. In my case I used it to power some LED grow lights and I used the 5V standby line to power a relay timer which would then bridge the PS-ON and ground turning on the lights. It was really handy to be able to have the power supply turned off instead of using a bunch of switched and leaving the supply turned on. This is going back 15 years so well before any wifi based timers were readily and cheaply available.
Great video, just subscribed. I'm a 31 year old college student in the middle of an AC/DC basics class. Because of the Covid situation I cant be on campus, I just learned about ammeters and this video is a great visual aid. I'm pursuing an associates in mechatronics, but this video is fueling a desire to continue my education into engineering. Thanks for being on RUclips.
I have been considering doing this for many years but never got around to it. However, your video reminds me that for cost of extra parts, the amount of time and trouble it takes to build this, I can buy a better power supply for less money. If you have the parts laying around and the time and want to learn, go for it.
cool :) thanks. maybe you can combine voltages to come up with new values. (-)12v(+)connected(-)12v(+) = 24v (-)5v(+)connected(-)12v(+) = 17v (-)3v(+)connected(-)12v(+) = 15v (-)5v(+)connected(-)5v(+) = 10v (-)3v(+)connected(-)5v(+) = 8v
Thank you ❤! So systematically explained such a well organized step by step tutorial! Thank you once again! I am now using an ATX power supply which was gathering dust. ❤ Love from India!
Finally, finally, a video that actually teaches something, no noisy background music, no video only type instruction, no heavy accent, no fast talking and excellent camera angles, along with excellent diagrams and presentation. Yes, I wish I had you as my high school electronics teacher. Maybe I would of attended more classes and actually learned something. Keep up the great videos.
Lol, I wish I had a Electronics class in High School
Me during highschool: *evident stare that doesnt know what an electronics class is or if it even exists...

I mounted it on the PSU box and it helped inspect circuit boards at times. I also added a custom 0V dock on the box for my multimeter - one wire frequently needs to be grounded.
Extremely clear, extremely clean... as usual !
Always a great pleasure to follow you.
Thanks a lot.
Please teach me the diagram of input voltage selector
This is fantastic. I took electrical training and the master test. I later took computer classes that included building a computer from scratch. Now if your video had been included with any of my classes.
I would have had a better understanding of why the connections were as they were. Instead of plug in play and pray.
Thanks for this incredible video.
This rocked as all of your videos do. I found your channel when I got into Arduino and I am hooked. Please keep up the great work! Subscribed!
I created and 3D printed the control panel. I'll post the files on thingaverse and add a link soon.
I feel the same way!
Link? As it's been 8 Months.
Could someone tell an ignorant novice the fuse rating used please, I can't find it, not for lack of looking
Splendid presentation! Excellent illustrations, articulation, and explanations. Last night I took apart an old PC to destroy the HDUs. I saved the power supply with in mind to use it as a bench supply. Came here to find out how and hit gold.
Outstanding presentation, THANK YOU SO MUCH. I have been on line for years but yours is the first i have subscribed to.
Hey All. I built this and it rocks! My power supply can give me 5V at 25A, way more then a $200 supply I saw on the net. The only issue was getting that 50W 8RJ resistor. I had to wait 2 weeks for it and now Amazon's not getting any more in. I also 3D printed the control panel and it looks cool.
If you're messing around with those WS2812B LED Strips, or motors, you're going to need a lot of power (amps).
Thank you for an awesome video.
Greetings from Australia, thank you so much for the detailed project, a true gentleman and genius , well explained and excellent show , especially adding the current /voltage display unit, excellent and back - to - basics switching approach
, thanks for sharing , can’t wait to make this project, I’ve subscribed, and definitely 200% thumbs up, champion!
Hi, friend. Watch my video.

TWO WORDS, SIMPLE AND EXCELLENT!!!!! Better explained, it is impossible. Thank you very much for sharing your ideas.
You, sir, are my new favorite channel!
One of the best channels for hobbyists and students on RUclips
Your videos are great, good quality and very well explained. Keep up the good work.
Bravo! You speak low and slow enough for me to follow you. You are, in essence, the Mr. Rogers of the electronics workshop. You make it easy for me to repair the Commodore Amiga's that pass to close my way by your creative prowess. :)
I agree for what you talking about it is well explained, I can relate to convert ATX variables power supply into personal projects, it’s very handy to run those 3 voltages specially in electronics as required, conversions, modifications is an interesting hobbies as long as you know what you doing, it’s a pleasure to achieve something like that specially for testing, very good on you, just keep it up peoples thoroughly learnings how to educate them through your knowledge regardless, Bless you
Hi Bill. Thank you so much for your detailed and easy to follow instructions. I've been looking for awhile for a tutorial on making my own Work Bench pc power supply. I am 76 years of age. I started in my teens and here I am still learning. I will be subscribing and following your channel from now on. Blessings
Thank you very much for your interesting and helpful videos❗️You explain every detail so clear that everyone can understand what you are doing. For me as a hobby electronic your selfmade easy projects are so good. Hope you go on... Regards, Boris🇨🇭
Hi, friend. Watch my video.

One of the most comprehensive and complete videos I have ever seen on RUclips or anywhere. Bravo, and many thx!
We decided to take a drink every time he said power supply my buddy died it was the greatest idea ever
yessssss i hhad samre idieaaa
I'm not an electrician but this is by far one of the best illustrated and conveyed video's on the internet, bar none! Great job my friend.
Got a spare PSU, been wondering how to convert it into a power supply for my Electronics Projects, Thank you awesome video good explanation and I have one of those meters that I've never used too, job done, just waiting for the parts.
Thank you for the excellent in-depth tutorial. Your method of wiring of the meter has yet an added advantage. I wired one into a similarly designed circuit, but used the output to supply power to the meter. An inductive spike from a load that I disconnected under power damaged the meter. I was able to troubleshoot and repair it, but had I used your technique, it would have been isolated from the load. In my case, I used a small “wall wart” to supply the meter.
How do you tell if a particular supply requires a load as in a 8 to 10 ohm power resistor? Thanks
I built this on to a black perspex panel (which I will box up properly later), and put a little voltmeter on each rail, (plus fused each rail). I added the V/A meter circuit too, so that I can feed a dedicated circuit when I am messing about with the little kits, and monitor things. The sense wires I have run out separately, so that I can use them as required. Many thanks for putting this up, it was extremely helpful!!
Hi man, great video! I love how clear you are explaining everything on your channel. Thanks.
I have a question. I made my ATX bench, and all the outputs are ok, but with a slight instability in tension, like +/- 0.02 volts, and when I want to use it to power my servomotors (controlled by Arduino), this slight instability makes my servos jitter very hard.
Do you know what can be de cause and/or solution to this?
Thanks in advance everyone!
This is absolutely the best electronic teacher and course, display I have ever seen. During this covid 19 crisis I seem to have time on my hands and this project really fits into my plans as I often need to check amp draw on automotive fans, pumps and stuff.
Excellent vid ! I'm looking at adding a bench power supply to my shop, and was wondering if one of these would make a good solution to meet that need . The clear well-measured narration was a GREAT help in following along with what you had in mind. All the BEST - and thanks again for a great vid ! - C.
I think this must be one of the best teaching videos on the tube, I found the presentation clear concise and informative. Well done Sir !!!!
Thank you for taking the time as always to make such a diligent video.
This guy actually knows what he’s doing and knows how to teach thank you very much
Can you create a parts list that includes links so we can get the exact parts?
This is madness.... so many worlds, so many characters, so manynstories combined into one series?!
I created the power supply. Would you like some pictures?
Link us!
Yes
Yes
You broke it down completely and made it look fun and easy. You are a great instructor.
Thank you !
Great video, well explained and very useful. Quick question - what rating fuses did you use for each of the 3.3v, 5v and 12v lines?
And what resistance resistors
Now that is a very beginner friendly video. Well Done! Only one hickup and i think it's major:
23:18 Don't crimp and solder! You solder low current lines and you crimp high current lines.
This is because high currents will heat up the wires and might eventually melt the solder. When the solder melts, it leaves gaps between all the tiny copper threads the wires are made of, thus massively reducing the area of contact between the wire and the lug. Now all the current has to go through these smaller areas of contact, heating the thing up even more.
If you are lucky it does not start to burn, if you are not, it does!
And that's why you shouldn't mix crimping and soldering!
from 28:07 ...........There is a distinct difference in the usage here of the term ------Ground -----
This is actually the minus (- ) ..negative rail. and not to be confused to Ground of the Mains. !!!
Totally agree...
The word GROUND should only be used to mean Earth/Ground. The green wire in your mains socket, the one coming in through the AC cord. That green wire is usually connected to the metal case of the power supply unit. It is NOT the same as the black wires!
They call it the "0V" rail, as in zero volts. The 0V rail provides a reference point from which the other rails can be measured; that includes the negative voltages.)
I liked the how you use wood to place all those components instead of taking the hard way drilling holes on the power supply itself making life a living hell of doing it without proper tools. But the wood is soft and easy ...i never thought of that..you are da the best
Thumbs up! Really good teaching, thanks.
Great use for an old ATX power supply! Following your directions in this video I cooked up one for myself, with one variation- I located the large heatsink encased resistor inside the ATX's case out of the way of anything and in the airflow of the fan. With it attached to the metal case, it doesn't put out much heat, but... I also reused a metal enclosure from an old car battery charger, and everything fit perfectly! I cut the back of the enclosure to expose the rear of the ATX so I could get to the switch and power cord connector, and buttoned it up neatly. Thank you for the share and keep 'em coming! I'm subscribed!
🤔🤔🤔was wondering, how did you not put the 5V rail to Ground with the load resistor in line between the 5V and Ground???
Thank you sir... thank you for posting this video!!!! This has helped so much! Thanks again.
This was a really good explanation and walk through and I wish I had seen this years ago when I first modified one of my spare supplies. It took me far too long to get everything figured out but I managed it and didn't die in the process. In my case I used it to power some LED grow lights and I used the 5V standby line to power a relay timer which would then bridge the PS-ON and ground turning on the lights. It was really handy to be able to have the power supply turned off instead of using a bunch of switched and leaving the supply turned on. This is going back 15 years so well before any wifi based timers were readily and cheaply available.
Excellent Video, Thank you for taking the time and doing this. I'm planning on building one, this has been very helpful.
@Jason Marquette Did you build one yet ???
Great video, just subscribed. I'm a 31 year old college student in the middle of an AC/DC basics class. Because of the Covid situation I cant be on campus, I just learned about ammeters and this video is a great visual aid. I'm pursuing an associates in mechatronics, but this video is fueling a desire to continue my education into engineering. Thanks for being on RUclips.
Always great and clear, as usual, Thank you!!!
I have been considering doing this for many years but never got around to it. However, your video reminds me that for cost of extra parts, the amount of time and trouble it takes to build this, I can buy a better power supply for less money. If you have the parts laying around and the time and want to learn, go for it.
cool :) thanks.
maybe you can combine voltages to come up with new values.
(-)12v(+)connected(-)12v(+) = 24v
(-)5v(+)connected(-)12v(+) = 17v
(-)3v(+)connected(-)12v(+) = 15v
(-)5v(+)connected(-)5v(+) = 10v
(-)3v(+)connected(-)5v(+) = 8v
i did it -12v with +12v making 24v for sensor and automation and it work fine
Okay, but note the current output is limited on the negative connections.
I have officially subscribed I love your videos you teach without being condescending, and it helps so much for someone like me
NEW DRINKING GAME! Drink every time he says "power supply" 🤣🤣🍻
Swapped it out for bong hits. Pretty blazed right now
Thank you ❤! So systematically explained such a well organized step by step tutorial! Thank you once again! I am now using an ATX power supply which was gathering dust. ❤ Love from India!
