Good day folks. Since I currently lack a bench power supply at work, I thought I'd take matters into my own hands and get one myself. Since it would see relatively little use with the workload I get around here, I didn't want to blow a lot of cash on it and get a "proper" one, so I turned to Ali once again and did an experiment to see just how much I can cheap out to build a lab PSU, so I found THIS.
Of course, I could've gone with one of those DPS modules and a laptop power brick or something, but what attracted me to this kit is that it's linear which albeit inefficient AF is supposedly better than a switching module due to low noise on the output....I already had some discussions on this in my threads about the two DPS-based PSU builds I did and how I was worried about the noise on the output being unsatisfactory for electronics...
Probably the only thing wrong with this particular kit is the caps, obviously, since they're bound not to be of particularly high quality, which can be worked out, but other than that the circuit seems legit enough. Even better: they offer the schematic, so if anything goes pop it should be easy enough to repair
