I had a spare 3D printer and 260-watt 12-volt power supply. With a simple modification, I converted it to a variable power supply range of 4.8 to 19 volts. Follow this guide: http://imajeenyus.com/electronics/20151028_smps_variable_voltage/index.shtml Then, I designed the case for it to incorporate the variable potentiometer, LED display, and two banana plugs. Parts: IEC plug (push-fit) Rocker switch LED display 0.56" - 30V 2 x Banana Plugs 1 Knob Electronics: 2k2 resistor 2K resistor 10k Variable Linear Potentiometer 47nF Capacitor
