That's why I asked. I was thinking it would be as easy as a voltage doubler on a 12V rail, but then I started thinking about some of the stuff you were saying. I was just trying to think of things i could do to it just for the experience of it, but I don't want to spend my time building shit, either. As it turns out, there is plenty to do just converting a computer psu to a benchtop powersupply. I have made one of these before from a cigar box, but it was just hacked together quick and dirty. I used it for quite a while and it never let me down, but this one is gonna be pretty nice.
I have one more power supply question, though. What is the proper polarity for the power cord? I don't see anything about c14 and polarity. I know it's really the device that will mind or not, but I want it wired the way it's supposed to be.
I said no more power supply questions, but I do have a mystery. I was just going to use my meter and check the cord, then it would be easy enough to tell how the male part should be. When I put my test leads in the end of the cord it blew the 8a250V fuse. I switched the positive lead over to the 10A jack before I did that, I usually don't. I can't help but think that had something to do with it. I felt a buzz as soon as I got both probes in there and I immediately snatched them back out, but it was too late. The cord works fine powering a tattoo machine powersupply, so I doubt the cord is faulty. I have never had that happen to me. Any advice what I did wrong?
