Desktop lab power supply

thingiverse

Dave Jones of EEVBlog did an excellent review of the D20V2A power supply module, a cost-effective DC-to-DC converter available on EBay for approximately $30. This project showcases how to transform this component into a compact desktop lab power supply. The holes in the case are designed to accommodate an M3 screw. To achieve a secure thread, you'll need to tap the hole. Don't be discouraged by negative feedback; PLA taps work well with minimal effort. To achieve a high-gloss finish on the front panel, follow this technique: apply clear acrylic sheet, spray paint one side of it, and then cut it out. Install the acrylic so that the unpainted side faces away from the user to prevent the color from being visible through the transparent material. For added flair, you can etch the painted surface for text or logos and reapply a contrasting color afterwards. When etching, keep in mind to mirror your design because it will appear reversed when viewed. For further details on this project, check out Dave Jones' YouTube video at https://youtu.be/hs__otW5GHk.
