Variable Bench Power Supply

This is a simple adjustable bench power supply I built to help me in my instructables. 8 ) Some time ago I build another using a computer (ATX) power supply, but this kind of solution provides fixed values: 3.3, 5 and 12 volts. This is the less expensive solution you will find (just if you have an ATX as spare), and is useful if you will work just with these values, but this is not my case. This project works with around 0.8V-29.4V ~ 5A.”
