A bench power supply is extremely useful for electronics hobbyists, but they can be expensive when purchased from the market. In this Instructable, I will show you, how to make a mini-lab power supply with a limited budget. It is a great DIY project for beginners as well as anyone interested in Electronics. Instructables Link: https://www.instructables.com/DIY-Mini-Lab-Power-Supply/ The Power Supply is based on XL4015 DC-DC buck converter module. This module can provide an adjustable output-voltage from about 1.4V, up to the input voltage and current output from 0mA to 5A. It only requires only a DC power supply with a voltage range between 12-30V. I have used a 24V/3A DC adapter. The power supply can be used for the following purposes: Variable Power Supply Battery Charger Constant Current LED Driver Solar Charger Controller Components Used: XL4015 Buck Converter: https://amzn.to/3qS4jir Volt-Amp LED display: https://amzn.to/37aZIAn 2 x 10k Precision Potentiometer: https://amzn.to/3ndO25c 2 x Binding Posts: https://amzn.to/3mdRHPf DC Jack (5.5mm x 2.1mm): https://amzn.to/342MnrS 2 x Rocker switch: https://amzn.to/3a09uqN Fuse Holder: https://amzn.to/378BVRk Fuse: https://amzn.to/3gCeeEi Heat Sink: https://amzn.to/2Kj8C5P 20AWG Wires: https://amzn.to/380lXYI Heatshrink Tubing: https://amzn.to/3qQOEzW 12-30V DC Power supply: https://amzn.to/379leVW
