Hi, I still have the EEV Blog diagrams though i really want build something much simpler with 4 channels at leastbrOften electronic projects are living well under 500 mA per channelbrThanks for sharing,brRegardsbrJean-François

why can't I just make one out of a variac, a microwave oven transformer and a rectifier?

Can we get a tutorial on the frankenstein resistor please? :D
Comment from : jonas duell

A quick note - just tried this with two LTC 3780, and both gave faults out of the box While trying to respect the "do not touch" the under-voltage protection pot in the end that needed turning clockwise a lot to get the fault light to go out and the OK LED to go on Worth considering in case you see this too -- thanks for an excellent video!

can someone tell me whats that background music called?
Comment from : Вук Ристић

Hello, Trying to make the same project and I'm stumbling upon a problem When I replaced the Vout potentiometer the reading goes from 0 to 25K Ohm only and the circuit is not working Tried to measure the 500K potentiometer and when it's not connected to the board it reads fine, but once soldered with extension cables (10cm long) it goes from 2 to 25K only The original and 2 other potentiomenters show similar values connected and all working fine by themselves not connected

Can i use 12V 208A - 240W led strip Switching Mode Power Supply with all protection and charging high amp batteries make video pls
Comment from : Geeth Perera

I used to watch these videos in college thinking when I earn I will make all this for myself Now, I am back here earning and thinking to start this again A great great thanks to GREAT SCOTT for all this content <3

Does the middle potentiometer even makes any changes mine doesn't make any difference when I rotate it
Comment from : Free Web & Mobile Apps

do you really use this power supply personally or you made this just fo the sake of youtube video?
Comment from : Abhishek Kumar

Can i use a toggle switch to short the output so i can adjust the amp ?
Comment from : Burak Ergün

Hello, we have an agricultural land that has no electricity Now, if we want to use a motorcycle battery, which is 12 volts, to get different currents, such as 10 or 12 amps, what transistor should we use?

Can we fix the buck boost module on a metal Cabinet with the cabinet acting as heatsink for the module ?
Comment from : Amit Ghosh

Is this power supply module available in dual rail type ?
Comment from : Amit Ghosh

Nice project, but I think instead of telling people to not try this project if they are inexperienced with electronics (because they have to wire a plug themselves) I would have told them to find another power supply that doesn't require you to wire your own plug An old laptop power supply would have worked well for a lot of people
Comment from : MrSpeedfox

i heard that the digital multimeter you used has a voltage range of 0 to 30(not sure or tested)
Comment from : GOYUM SANDEEPA

how does it look on an oscilloscope on and off load ??
Comment from : Abdelhamid Khattab

I know this board gives a minimum output voltage of 08v, how to reduce it to 0?
Comment from : Đô Hà

is this short circuit proof
Comment from : EEI

Isn't under voltage protection important if you're powering this with a battery to prevent over discharging?
Comment from : wills4705

Very helpful video, thank you I was able to use a lot of the information you shared to make my own power supply: youtube/9PlQcmx1cBQ

Another good video Yes there were some things that could have been done better but other than not including a fuse I look forward to the next video
Comment from : Odyssey In Electronics

Bro, hold the terminals when you torque down those screws! Had me cringing thinking the solder joints were about to snap 😂 Awesome build though!

wonderful explaining
Comment from : KITT BELL

eeeh, why bother about grounding that will just trip the GFCI
Comment from : Albin

I built a variant of this power supply 6 years ago as well as a smaller one of a different design about a year later Six years on & both bench power supplies are still going strong with my using this variant just this evening to help build another electronics project
Comment from : GuRu Incognito

You can build a variable voltage power supply that goes up to 12 volts with an old PC power supply
Comment from : O the minecrafter

Hi, so this project will have same functionality as variable bench psu of which I actually wanted to buy to make use of the current limiting feature but cannot afford because of financial constraints Will this be able to help me troubleshoot laptop motherboards when in SHORT??
Comment from : Reagan Sansoucie

What about the noise? IS the circuit noise low or high? Please let me know because I will be building this
Comment from : At A Glimpse

What about the noise? Doesn't the circuit have noise?

Is it only ac supply

Boy those Chinese screw terminal always seem like they're one turn away from being ripped off the board ;)

I will make this, but the enclosure will be made of plastic

Can you use 250k ohm resistor instead of 200k ohm? Please reply quick

I just put a fuse to be safe and a colling fan
Comment from : Cat the comment bot hunter

The potentiometer need special mounting, do not mount it on front panel directly - there is a way how the amators do it

Used a bench power supply to build a bench power supply How ironic

Hello can you make a small variable 30v power supply please, it's for my individual project please, with schematic please love from Philippines ❤️❤️❤️
Comment from : aLvin87 ِ ِ

Nice, but i probably would have used a more powerful supply, 12V 10A Not because I need 10 amps but because I know those chinese power supplies very well and they tend to fail if you use them to their full rating without taking a look inside of them and improving the heatsinking, some solder connections, and sometimes change some questionable capacitors

Thankyou for the 'cup of water' tip - I'm building a power supply, and today's testing will include redistor current dumpbrYour advice probably saved my workbench ❤

I want one, But i need one who can do 12V 60Amp???

I LIKE THIS ONE ☝️
Comment from : SILVATRAOZ

Could someone provide a purchase link for the box as in the video?brI've been looking for it but can't find itbrI would be very grateful if someone was willing to provide the link
Comment from : MFR04

If you don't want to deal with high voltage AC wires, there are power supplies which have a plug just like the one on the back panel, except directly onto the power supply brbrThese are usually put into servers, so you gotta trick it into thinking that certain contacts are connected by shorting it with a resistor (all external and low voltage work) Plenty of tutorials online

Can I use a 24V 17A supply instead of the 12V 5A?
Comment from : Tiaan Nel

Whats name of the black power supply you are using?
Comment from : AFGHANISTAN TECHNOLOGY

Not like this! No capacitive or inductive reactances on lab power outputs
Comment from : Nix Nax

I know that it is unimportant, but you changed at the first try of the 12v 5a power supply neutral and live

Comment from : Naldo Silva

as far as i see the ltc3780 should not go up above 80W without an extra heat dissipation how can we manage this with two potensiometers? thank you
Comment from : stortoaranci

1 It's NOT mandatory for current limiting A current limiter is extremely easy and simple to build, requiring only four components including an ammeter, and can be added to any ol' nasty power supplybrbrIt's nearly never worth your time to build a variable-voltage variable-current power supply because it'll cost you four times as much money in parts as a complete functional Chinese power supply from Amazon complete with about three thousand five-star reviews
Comment from : Tim Hofstetter

Hello Scott I think you missed something very simple and must in every circuit, that was the fuse brbrAlso as an upgrade you can also include reverse polarity, short circuit Which I think you have already included in another video

Comment from : Mouleesh waran

If your gonna try this id recommend getting a wall adapter (idk the word) like an old 12 volt charger to try it out first so you dont kill yourself Otherwise use the hand opposit to your heart (ussually the right) so that if you get a shock theres a lower risk of heart faliure Good luck! sry for bad english btw

I have watched a few of your videos and wording if I can get some helpbrbrI need to make a power supply that will output 12 volts @ 30 amps Any know how to help me?
