GMH 055 DIY Portable, Battery-Powered, 1-37 volt Power Supply

This DIY project takes an unused tobacco tin with a handful of parts and turns it into battery powered, rechargeable, 1v to 37v adjustable power supply. The center of the project is an XL6009 Buck/Boost converter. By swapping out the 10K trimmer pot on the board with a full-size Helipot and precision adjusting knob it’s possible to dial in the precise voltage needed. The LED displays both voltage in red and amperage in blue. The various outputs include a full sized USB, 2.1mm, and banana jacks. The project case was wrapped in Carbon Fiber Vinyl to give the power supply a much more modern look.
