My local Makerspace has some shelves called Hack or Die Anything on these shelves must be taken for a project or within a few weeks it willed be binned. I found a rather nice Network Attached Storage device made by Netgear which obviously didn't work or wouldn't have been sat on the shelves! However, the case was extruded aluminium and rather nice. Sat right next to it was a 50V server power supply that looked almost the right size to slot inside the case. And with slight hacksaw modifications it did. Ebay provided the rest in the form of a programmable dc-dc converter with a display for current and voltage. The result is a 0-50V variable power supply with programmable settings, voltage and current displays.
