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 wiring diagram in the pictures)
Parts:
Buck converter: https://www.aliexpress.com/item/1005002279425631.html?spm=a2g0o.order_list.order_list_main.490.56c218020XwKlG
Wire
Preferably red and black to make it easier for yourself.
Old Laptop power supply: 12-36v
I recommend taking a look in your local thrift store, or looking at home it just needs to be relatively small and the buck converter will accept anything from 6-36v 1-10 amps
