Buy a basic electronics book. I'd suggest the ARRL Handbook, but there's tons of others. Or search the ARRL's website (www.arrl.org) for power supply projects. All the components you need to build such a power supply can be had at Radio Shack. With a little patience, a multimeter, and the right source of information ANYONE can build such a power supply.
