# DIY variable power supply ## Introduction I built this because I needed a lab power supply and all the lab power supplies I could find online were too expensive. This is built with 4 necessary components and the rest is optional. ## Supplies. - SK-60 or SK-120 buck boost converter (The SK-120 may not fit as I made it for the SK-60) - 60 watt usb-c pd power supply (or 120 watt depending on which buck boost converter you have) - 4mm banana female plugs - Wires ## Optional supplies - XT-60 connector - Any other connector you want to put on it ## Equipment - soldering iron - 3d printer - glue gun ## Build If you have everything it is very simple. Everything is marked on the Buck boost converter (SK-60 or SK-120) where the power goes in and where it comes out. The USB-C PD module is hot glued in. It has held up for 5 months so far inside while being swung around in my backpack. When hot glueing the module in I inserted a usb-c cable inside of it so it would be aligned well. ## Tips - If you use this design make a cover at the top because otherwise assembly is very difficult. - If you use an XT-60 connector make sure that the side with the corner is the ground. ## Contact For any other contact just message me on signal @Smikkelbakje.01 ## Pictures ![Foto](/md-assets/IMG_6547.jpg) ![Foto](/md-assets/IMG_6548.jpg) ![Foto](/md-assets/IMG_6549.jpg) ![Foto](/md-assets/IMG_6550.jpg) ![Foto](/md-assets/IMG_6551.jpg) ![Foto](/md-assets/IMG_6552.jpg)
