Easy DIY Power Supply 80 Watt! Instructions: Print the parts and press fit the buck converter and button. take your laptop power supply (consider taking it apart for better airflow/making it fit, but only do this if you are comfortable doing this) then there are two options you can play with 220v which I don't recommend, and therefore will I not explain how to do it or you can print the "back easy) and just slide the 220v cable up in the slot. then glue the power supply into place with some hot glue and run the output wires into the input on the buck converter, MAKE SURE PLUS GOES TO PLUS AND MINUS TO MINUS (see the picture in aliexpress) now get some wires and run the output positive to one side of the button and run the other side of the button to your + banana plug. Then take your negative or neutral output and run to the - banana plug. now close it all up I used wood screws and enjoy. (i have added a wire diagram to make it easy to see wire) Parts: Buck converter: https://www.aliexpress.com/item/1005002279425631.html?spm=a2g0o.order_list.order_list_main.490.56c218020XwKlG button: https://www.aliexpress.com/item/4001165112842.html?spm=a2g0o.order_list.order_list_main.480.56c218020XwKlG wire Old Laptop power supply: 12-36v banana plug/terminal: https://www.aliexpress.com/item/32871933115.html?spm=a2g0o.detail.1000013.2.6a2933a3jwvscP&gps-id=pcDetailBottomMoreThisSeller&scm=1007.13339.291025.0&scm_id=1007.13339.291025.0&scm-url=1007.13339.291025.0&pvid=2ec1120a-fd9b-46d3-a367-d4f5dd5ff26b&_t=gps-id:pcDetailBottomMoreThisSeller,scm-url:1007.13339.291025.0,pvid:2ec1120a-fd9b-46d3-a367-d4f5dd5ff26b,tpp_buckets:668%232846%238113%231998&pdp_ext_f=%7B%22sku_id%22%3A%2265526350625%22%2C%22sceneId%22%3A%223339%22%7D&pdp_npi=2%40dis%21DKK%2117.66%2110.58%21%21%21%21%21%40210323b516715728853464930e54d7%2165526350625%21rec If you got any questions shoot me a comment or an email at: niko469aa@gmail.com
