Power Supply
thingiverse
This DIY power supply combines a step-down DC-DC LM2596S, a voltmeter, and a 12V to 5V step-down regulator for two USB ports into one compact unit. The voltage can be easily adjusted using a single potentiometer, while the dual display simultaneously shows both the original voltage and the voltage after adjustment. The entire assembly is housed in a custom-made case crafted from a laser-cut plexiglass plate and complemented by two 3D-printed components.
