@bellluna9017 : Just waiting for the Veritasium internet geniuses.
@Watchyn_Yarwood : Excellent, as always! Your animations and explanations are spot on. I would like to see an in-depth video just on three phase. I find it fascinating yet difficult to understand.
@tomg921 : Your video's have a way of explaining a complex subject very easily. Wish your videos were available 55 years ago when I was learning about AC power. Thanks
@zmsays : Thank you for putting this together and making it so much easier to understand!

This time we make this unique looking 180W Lab Bench Power Supply Unit/Battery Charger from some spare components, scrap parts, \u0026 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 \u0026 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!

@MaxImagination : Hey everyone! Thanks for watching! This DIY Power Supply has also been featured in the Australian "DIYODE" Magazine!

@bru57000 : WARNING ! RCA sockets are not designed to feed current (2amp max), use banana sockets instead (10 or 15 amp max)
@rickymeadows5176 : 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 !
@saptaksarkar30468 : 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 !
@saponi2 : Great job! I built a similar power supply a while back and used almost the same components. You added a few things I hadn't thought of. Great job!
