--------------------------------------------------------------------------------
This time we make this unique looking 180W Lab Bench Power Supply Unit/Battery Charger from some spare components, scrap parts, & the main module to this project being this Digital Step down converter Variable Power Supply module.
With an adjustable DC output of up to 36 volts & 5 amps out of this cool little box, the applications to what you can power with it are endless... From prototyping with fun circuits, to testing whichever components you need to test, to even powering a common household device through this thing, a power supply is a hands down essential apparatus to have at your workbench!
This DIY Power Supply has also been featured in the Australian "DIYODE" Magazine!

@spongerobert Жыл бұрын

@@MaxImagination Your way is better if you're doing everything from scratch. I would maybe do it in 2 parts. Regular ATX PSU to supply the 12v and 5V and then all the other doodads in a separate case but adding easy battery connectors is a really cool idea as it makes it somewhat portable. Or even better, power the whole thing with an old laptop power brick especially if you have a beefy 130w brick lying around.

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!

How are the batteries and laptop adapters "less stable"?

@MaxImagination Жыл бұрын

Batteries may be the most unstable, but laptop adapters do not have variable output power - is what I probably meant.

@jeffbaker8808 Жыл бұрын

@@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.

Great video what is cost of making this bench power supply?

@MaxImagination Жыл бұрын

Hi there. Thank you! The total build cost may vary from USD $35-60 depending on what you don't yet have in terms of parts.

@@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!?
