    Hello People

    I deicided i wanted to have my retropie setup on a more portable setup so i deicided i buy an old gameboy.

    So anyways , my setup is a rasp pi b+ 18650 4400mah and a 3.5″ lcd screen.

    I´ll just post a few pics and add more info later. The usb/network ports are covered by a game cartridge not show in the pics.

    SLowly getting there. Only thing missing atm is the following:

    Install speaker and amplifyer
    Position the screen in correct place and hot glue it to place.
    Change screen settings in configs file.
    Wire up all the buttons to the GPIO pins
    Small wire cleaning.

    I use a 1 cell 18650 charger to charge the 2 18650 cells. That is then connected through a power switch ( used the original one positioned in the volume slot ) and then to a dc-dc conerter that takes the voltage up to 5.2 volts.

    The LCD i could use on 5 volts without any mods so i got lucky :)

    More to come later on…..

    And here is a short video showing it. In the video i use a snes controller since i havent wired up the buttons to the GPIO pins yet.

    Need to put the micro usb connector on straight later. But really happy that the case closes perfectly. Atm its just closed with 2 pieces of black electrictape but will be closed with screws later on :)

    Soon time to start on the second one. After i showed pics to my friends i got a few orders :)

    Nice project!

    I just started something similar with a 3D printed case. I’ll actually be using one of those cheap usb snes controllers and soldering the leads directly to the pi rather than messing with the GPIO pins, maybe something like that would be an option for you.

    Kind of like this (although I’ve found a way to keep the controller PCB in-tact with my build):
