A while back I built a powersupply from an old ATX PSU, and while it works great, I wanted to step up my game with a digital powersupply. As already said, it is powered by batteries (2 lithium cells to be precise), and it can deliver a maximum of 20 V at 1 A; which is plenty for most of my projects that require a precise powersupply.
