Shop made bench power supply.
I have an atx dual sata 550 watt power supply... I have seen a bunch of instructables on here that allow just a few different voltage selections.. I have also seen a few with potentiometers to allow it to be more adjustable (dial up or down the voltage).
That is what i want, i dont want to be limited to just three different options. S my question to you is, what type of potentiometer do i need to buy for this? And will a regular autostore purchased dashboard voltage meter window work?
Also, what type of fuse/or breaker should i use?. Do i even need one? I also head i need some kind of "switch" for this as well. I found circut diagrams, i found list of items needed, but most of the instructables ihave found arent very specific on the specs of these extra items needed... Any help or direction would greatly help. Im going out to radio shack today and would love to grab the items needed to finish this priject.
