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!
