This is my first instructable. it is a simple method to change a 2 battery (1,5v) gameboy advance classic to use USB instead.
!! WARNING !!
this is a no warranty instructable and i done this knowing that i could have burned the gameboy.
What you will need:
3 diodes 1n4007;
its is simple to make its just soldering exactly like the last diagram shows.
5v USB ------------>|-->|--->|---- +Battery Gameboy
GND USB ------------------------- -- Battery Gameboy
This will convert the 5v usb to ~2.9v.
I tested playing with a few cartridges i have and so far: no resets happened, no smoke coming from the inside, no heat problems.
unfurtunely i dont have the internal photos 'cause i closed the back before i could take photos and right now the gameboy is with my cousin.
Thanks for reading,
