Hey everyone! Thanks for watching! This DIY Power Supply has also been featured in the Australian "DIYODE" Magazine! Read and learn more about it from their 60th issue here: diyodemag.com/features/project_power_diy_variable_lab_bench_power_supply
Its a really cool thing...but im just a pc techie and you lost me at about 8 min so I had to go and find the "for dummies" versions of all the other stuff, cool vid though 👍🏻
Love seeing younger generation folks taking initiative to do projects like this ! After 40-years of being a machinist , I watch their skills using crude tools & angle grinders & think to myself " my God, what could these kids build if they had access to a bonafide machine shop " ? Great vid !
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!
That’s not necessarily true, I have a really thick high quality cord the auto rca on it is small but the video you can tell it’s a lot thicker wire and you can see the connector is beefer. I use it with my amateur radio, I’m sure there is quality ones that support more amperage from radio / video equipment stores
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
You have done a great job on this tutorial. Not only did you put a lot of effort in explanation but also provided links for everything ! Shows that you really motivated for this project and tutorial. I wished every tutorials were like yours'. Keep going, you have a bright future ! 👍
Good job on this, helps a lot on ideas. Only thing I would suggest having worked with Lion batteries for so many years, the actual voltage of the battery is far more important than an indicator light. If the voltage is
Thanks for your comment and pointing out this interesting but important key thing about Li-Ions. I've charged old cells that got pretty warm when charging but still charged up. Yes, they are probably the most unsafe battery cells to work with, so precaution is number one. I appreciate your input on the project, good for others to keep in mind as well. Cheers!
Yes! It sure is a super duper handy device to have on any maker's workbench, especially with multiple user-friendly features in one box. Thanks for your comment! :D
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
This power supply is action packed with features plus all components can be sourced quite easily. In the end you have an invaluable tool for most electronic projects. Using recycled parts is also a huge bonus!
Hey, Epic build. Just a tip. It will be easier to put the metal plates under/behind a old piece of wood to drill holes in it and so they wont bend also. 😉
Honestly i'm not a fan of the phono sockets as they are not high current connectors, as you suggest 4mm jacks would be better, but i appreciate you're working with what you got. Also props for making a point about earthing/grounding, it's a life-saver and many people skip it.
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!
Using the RCA jacks for the variable power was slick. I wondered if I would want some your features more modular but your design saves soo much space and works so well integrated, it's really hard to argue for it. great job.
What a great device. It's multifunctional and usefull device. One thing though. I saw you commented on another Electric DIY UA-camr video. He had bunch of fake videos in his channel. Please don't give them credit by commenting on their videos.
@@MaxImagination I think I replied to your comment that time. Now I don't remember the channels name. The video you commented on wasn't fake video, but that channel had lot's of fake video too
@@MaxImagination The bad thing is that you put lot's of effort and work on your projects but your viewers are about 20k-30k. The fakers have millions viewer and subs. This is the worst part of UA-cam.
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
@@MaxImagination that makes more sense then. I'm watching this because I'm trying to make my own power supply for my tattoo gun out of scrap stuff I have lying around.
It's currently the tool I'm using most at my workbench. Also, the 18650 cell charger couldn't have been a more handy integration. Thanks for your comment!
Good Work Very Good, I recommend using a Transformer as power supply instead of switching power supply, Transformer will last way more longer than SMPS But very good though
Best DIY Bench Power Supply video I have yet seen. And I’ve watched a lot of them. I might use your PVC pipe method you used with your recent RC car body instead of the boards, otherwise it’s pretty sweet. Glad I found your channel
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.
And a lot is what it needed! I couldn't be more glad with the way it turned out, all working well, it should be the source to many more upcoming projects. Thanks for your comment, James 🙂
You and Linus techtips are my favorite tech channels now. Very fun even with someone who has limited experience with these things. I will be looking forward to your future videos. I hope you grow to 10 Mil someday!
Holy crap, I came across your channel by chance and I have to say... MAD RESPECT my guy! It's really amazing to see someone your age taking on and sharing such awesome projects and DIYs, keep it up! You've definitely got a bright future ahead of ya!
Hi! Thank you. I now use ABRO epoxy, I might've linked something like it below in my affiliate store front in tools and supplies that I use. Check it out. Cheers.
It would be nicer if you posted the full circuit diagram with all the different parts shown, As it is one has to figure out things here and there and do a bit of guessing too. Is it a tall order?
The full circuit diagram is linked in the description, hand-drawn. Yes, you have to do a bit of thinking too to make an intermediate project as such come to life!

Might as well just buy one going this route. I’m looking to build one from components. Yes I will say it looks pretty good but how much do you have in it as far as cost?
I made the mistake of purchasing the SMPS converter when I could have used a PC ATX supply unit. One could save $20 here. I spent a total of around $50 making this PSU.
@@MaxImagination Your way is better if you're doing everything from scratch. I would maybe do it in 2 parts.

Hi there. It works for me fine as it is, I use it every day for testing my circuits. If I were to improve it, I'd probably just add a fuse at the AC input and some better connectors for power (|Banana Jacks). Apart from that, it works good and I don't think it is worth making an upgrade video. Cheers!
Sure. Check the diagram here again: drive.google.com/file/d/1xT-7rCxKNZLwKLg-iPQoXNK4AownCvSo/view?usp=sharing It uses a 10K ohm variable resistor (potentiometer) and a 2.2K ohm fixed resistor.
How about taking a solar birth bath and making it into a solar water pump that you can pump water out of a 5gallon water bottle into a hose so you can water a garden in places where you done have water
Or you could just fill up a watering can by hand the way people have been doing for 500 years. Not everything needs to be solar battery powered, my friend.
Hi and yes. The case may be 3D printed as long as you place suspended supporting posts for modules to be well seated, open space for heatsinks (to prevent meltdown). Insulating connections would still be a good idea, even with a plastic case. Cheers
@@MaxImagination I bought a 60W power supply for a rack based PC and hopefully can add a variable step down transformer with digital display for voltage n current, stick it in a box n be done with it!?
@@MaxImagination true, although variable laptop power supplies are available. (I have one.) There is a switch, so you get fixed voltages, for example 12, 15, 16 18, 19, 21 and 24 volts not variable, which I realize was the objective. Current limited to max amount; short circuit protection included.

Reminds me of my self when I was younger, but your better at it now than I was until I was nearly 35!
WARNING ! RCA sockets are not designed to feed current (2amp max), use banana sockets instead (10 or 15 amp max)
Thanks for your tip. However, if modified correctly, the sockets should work fine for carrying that amount of current.
Better yet, use Anderson Powerpoles

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 👀
Awesome video Max...
Glad you enjoyed it, thanks :D
Warning !!
The LM7805 will be very hot when it use for charging the battery, better used buck converter module with PWM feature.
True. I suggest using at least two LM7805 ICs or one LM2596 DC-DC buck converter.

Hi Max,
11 months on and with the benefit of hindsight, is there anything you would do differently?
If so, would it be worth a v2.0 video?
Thanks.
Hi there. It works for me fine as it is, I use it every day for testing my circuits.
If I were to improve it, I'd probably just add a fuse at the AC input and some better connectors for power (|Banana Jacks). Apart from that, it works good and I don't think it is worth making an upgrade video.

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
Sure. Check the diagram here again: drive.google.com/file/d/1xT-7rCxKNZLwKLg-iPQoXNK4AownCvSo/view?usp=sharing
It uses a 10K ohm variable resistor (potentiometer) and a 2.2K ohm fixed resistor.

Or you could just fill up a watering can by hand the way people have been doing for 500 years. Not everything needs to be solar battery powered, my friend.
You used very powerful power supply which can output 20A at 12V but you used 5A step down converter why?
That's so I can give it future upgrades with higher power step down converters and other power-related peripherals such as chargers.
How's the ripple voltage?
Hi. I haven't yet tested my lab PSU on an oscilloscope as I do not have one. Cheers.
Very nice!
Thanks for the visit!
Where do I find the thermal activated fan switch
Hi, Robert. You might find something commercial online or you make it yourself.
So what's the polarity? Is it indicated in circuit diagram?
Polarity of what?
Could one 3d print the case and other stuff. IAny worries about fire or melt down.
Hi and yes. The case may be 3D printed as long as you place suspended supporting posts for modules to be well seated, open space for heatsinks (to prevent meltdown). Insulating connections would still be a good idea, even with a plastic case.
Cheers
I want a BOM and schematics, pretty please xo 🙂
You can find the parts/components list and diagram in the video description.
@@MaxImagination I bought a 60W power supply for a rack based PC and hopefully can add a variable step down transformer with digital display for voltage n current, stick it in a box n be done with it!?
How are the batteries and laptop adapters "less stable"?
Batteries may be the most unstable, but laptop adapters do not have variable output power - is what I probably meant.
@@MaxImagination true, although variable laptop power supplies are available. (I have one.) There is a switch, so you get fixed voltages, for example 12, 15, 16 18, 19, 21 and 24 volts not variable, which I realize was the objective. Current limited to max amount; short circuit protection included.
