Add a User Interface with Presets to Your Power Supply
A few years ago, Elektor published a 30-V, 3-A adjustable benchtop power supply dubbed UniLab2. To keep the total outlay down, it had a rather basic user interface. The Elektor Labs project highlighted this week offers a slick user interface for the UniLab2 by adding rotary encoders and a 4-line LCD. On top of that, you get handy presets for 3.3-V, 5-V and 12-V output voltages.
