Comming soon, "Building Power Supplies" Tutorial

UP-UP-UPDATE!! Check THIS POST for the first of two (or more?) power supply tutorials I wrote for Instructables.

Every project needs power, and every hobbyist needs a variable bench power supply. It's a surprisingly easy item to build, either from scratch or scrap parts, and you'll get lots of mileage out of it.

We'll look at the components of a linear power supply, and various ways of building them. Some are safe and simple, others require working the 120V line voltage of your home. Use with caution!
