I am posting the schematic for a dual output lab supply I designed some years back and built for my own lab bench. It's a good learning project and can be simplified or built fully depending on complexity level of the builder. I am going to try to post the PDF file, then I will add technical info if it does go through.... to save a half hour of typing only to find out it won't post.
Previously used computer supplies can often be adopted for use as bench top power supplies. They are usually dirt cheap in any shop that sells used computer stuff. They have numerous fixed voltages already, and with some mods they can be turned into variable supplies.
