Tim's GBZ [WIP]

[Tim]

Hi guys!

so i started my build probably a month ago and i'm nearly finished. The only parts that i am missing is the powerboost and a 18650 cell. My goal with this project was to keep the Pi removeable. I did that by using a GPIO-Ribbon-Cable. Because no Teensy or USB-Hub was used, i saved a lot of space to realize this.

Main parts i used:
-Pi Zero (of course )
-Gameboy Replacement Shell
-PRS-Tech 4-Button PCB
-GPIO-Ribbon-Cable
-Mini HDMI to HDMI Adapter
-PAM 8403 Amplifier
-Gearbest Screen
-Buttons and Buttonwells from a fake SNES-Controller

I started the project by drilling the X and Y holes into the case. I had bought an 10.5mm drill bit but in the end i used my dremel because the big drill really messed up the plastic around the holes even tough i pre-drilled them with smaller bits.

Next i cut out the sreen bezel with my dremel. I used some tape to mark the area that is needed to hold the screen protector.

For the L and R Buttons i wanted to use the original buttons that came with the Shell so i also put some 10.5mm holes in the back.

While i was doing the electronics inside the Gameboy i was that hyped of finishing it that i absolutely forgot to take some fotos . This is how it looks now:

You can see that i placed the Raspberry quite differentely than most others because i needed a lot of height to fit the GPIO-Connector.
In the battery compartment i already made space for the 18650-cell and it fits perfectely. The PCB's for the L and R buttons between the Raspberry and the battery compartment are hold in place with some metal pieces out of a food tin that i bend and superglued in place. The halves of the shell are removeable because i used connectors wherever i could. I also wanted to use a full HDMI output for using standard cables. After a bit of cutting, it fit nicely. The lowpass-filter is hidden right under the pi. It's outputs are bridged together with two 2.2kohm resistors. The headphone jack, volume wheel and the missing USB-port still need to be glued in after testing.

From the outside my Gameboy looks like this right now:

The buttons from the SNES-Controller are too small but it works and i can fix that later. For the Screen cover i used the one that came with the Shell. I removed it's paint with some nail polish remover and painted the new border with Grey nail polish. I didn`t pull the protective film off yet, so there are a lot of bubbles and scratches visible.

I probably made a lot of mistakes in writing this because i am still learning English, so feel free to correct me . (and comment)

hey that mini hdmi to hdmi is a great idea did you make it like that or was it just a simple take it out of casing that the parts came in? if this is the case can you post a link to the kind you purchased? If not where you bought parts and wire gauge?

I used something like this:

but the cables inside are very short so you don't have much options with placing the pi.
I think this has longer cables inside:

Thank you this really helps me a lot! going to use this in my second build.

Hi Tim,

Are you able to use HDMI or composite without changing your settings? (HDMI ON if wired at startup, else composite ON)

Good job for your GBZ
