DC Variable Power Supply
This project is a compact, adjustable DC power supply built around a DC-DC buck converter module sourced from AliExpress. It features an integrated LCD display that shows the output voltage and current in real time, making it easy to dial in precise voltage levels for electronics work and prototyping.
The enclosure is custom-designed and 3D printed, housing the buck converter module, a power switch, and a DC barrel jack for input. The design keeps everything tidy and accessible, with the LCD display mounted on the front panel for clear readability during use.
