I had to merge my "lab" with my living room to make space for a future flatmate. That means I pull all my projects from their dark, lost corners and places, see their flaws and want to revisit them. Like some of you told me, I was not really going to use it, since it was way too loud, big and other good reasons. Some weeks ago I got some old laptops with 19V PSUs and I thought that with the regulator I bought this would make a good PSU instead. With a ten-turn potentiometer and a 4euro voltage and ampere meter display it could get quite useful.

The wiring was a bit tricky, I will need to write it down or make a sketch for it. There's also a 3D printed case (almost) now!
