“This article is the first in the “Projects” category. It’s a very inexpensive way to make a pretty good DC bench supply or dedicated 12 volt supply for working on projects or powering devices. As of this writing, a good quality and powerful ATX PSU (power supply unit) can be obtained online for about $20.00 or less. With the addition of a few inexpensive electronic parts (binding posts, LEDs, resistors, and some bits of hardware) a person with moderate electronic skills can do this project.”
