I am an avid viewer of Dave Jones’ videos on YouTube and really like his series of videos on power supply design. I actually decided to go along for the ride and make my own unit, because my current power supply died some time ago. I went with the revision B version of his design, but modified it a little to suit my needs. The first version that I built only does away with the USB jack, but the second version that I designed also gets rid of the µCurrent circuit and removes the push buttons from the board. My design is better suited to go inside of an enclosure with buttons already installed. The rotary encoders are mounted to the board, but one could easily run wires to a pair already mounted on a front panel.
Below are some pictures of the first version.
