DIY battery powered power supply

thingiverse

This is a project to build up a DPS5005 (or similar) into a Ryobi One+ battery powered adjustable power supply. You will need: - 3D printed case - Ryobi One+ battery - DPS5005 power supply or equivalent (DPS3003, DPS3005) - Combined red/black binding post - 2 spring contacts - 2 screws for securing the spring contacts - 2 ring connectors for attaching to the spring contacts - 2 ring connectors for attaching to the binding posts - 18 inches of 18 gauge wire. Assembly of this kit is pretty straightforward, but may require using some tweezers since you have to work down inside the 3D printed case. A completed assembly can be seen in the last picture. Four wires are involved: +/- from battery to DPS and +/- from DPS to binding posts. I offer a few electrical component kits on ebay at https://www.ebay.com/itm/142614452091, as well as the complete case and electrical kit for sale on ebay at https://www.ebay.com/itm/142868063866.
