Bug's first Pi 3 Gameboy (No AIO)

Post by TheHappiestBug » Tue Nov 07, 2017 6:36 am

Hello,
I'm starting my first* GB3 Build and have almost all the parts. I am NOT using an AIO.

Pi 3
GB shell
Button sets
Rubber pads (accidentally got nes pads, have to trim them) Now using 2x sets of GB pads
Kitsch-bent pcb
USB audio (still in mail)
Small Speaker
Arduino Pro Micro (broke my first one, new one in mail)
USB port
-Charging circuit/step up circuit
Micro USB port-
Now using powerboost!
BW screen
2x psp joysticks
Clear cartridge shell
Lots of hot glue sticks
3d printed parts (screen bracket, button holder, button guides, screen jig)


So far I have stripped the pi 3 (check out Eccho's GREAT guide), tested my case mods on an old DMG, and set up Retropie settings. I really liked sotasystems build, and plan to use the psp joystick guide he made (I had it working till I bricked the pro micro)

I want to thank HoolyHoo for his awesome 3d printed parts, moooarcuuuus for the same, Wermy for starting everything, sotasystems for guides, and Chedda for the excellent Pi 3 pad pin-out. (pad-out?) Will update with pictures soon!

No pics yet (sorry) but last night I did carve out the battery compartment and test fit pads. The cutting of my nes pads were uneven, so I ordered some GB pads. My 3d printer (a printrbot play) is out of commission for a broken hotend. :( I'm trying to print my parts somewhere else, but no luck so far. I'll try and post pictures tonight, and then post more when I get some parts printed.

Here are some pictures of the stripped Pi 3! I went the I-Don't-Trust-Myself-With-An-Iron route and removed the metal casing on the ports with my flush cutters, clipped each pin down, then removed the plastic interior and trimmed the pins very short. Because I went this route, however, I'm using the pads for data. Thanks again Chedda! :D I removed camera and display ports by using the cutters to remove the plastic outside and desoldering/triming each pin. I covered both in electrical tape and accidentally ripped of a few pads, but thorough testing showed that the pi worked fine. I did basically the same thing for GPIO. I just cut really hard, removed plastic, and desoldered/trimmed. I did nothing to the HDMI, because i'm not skilled enough to go anywhere near that thing. :lol: I found a way to get my parts printed, so more updates coming (at least by Sunday). I may do a post about the general outline of my build in the next few days (I love it when build logs have those)

My parts are being printed, and I can update more later today. Right now I wanted to do a general outline of my build: I wanted to use a pi 3 for the extra power so I can play n64 games on the go. This is my second gb build, but my first was awful- I wasn't using real tools, I had a hack saw, some screwdrivers, a broken soldering iron, and a hot glue gun. That was it. I did everything on the floor of my garage. As you can imagine, this didn't work out. I eventually trashed the case and just kept the parts. That's why this build was so inciting-I ordered about 40$ worth of stuff off kitsch-bent and already had the screen, battery, and my pi 3 (that was the one for personal use). I had a broken GB I bought for 15 dollars, so I've been testing mods out on it.

Anyway, I want this build to be somewhat basic- a d-pad, an analog stick in the middle, and A/B/X/Y. I have some black SNES buttons I'll be using for L/R and some tactile buttons for L2/R2. I have a 5 position switch I was planning to use for C-buttons, but since I'm using a pro micro that won't work. I've heard a lot of people say that they never use the d-pad In n64 games, but one of my favorite n64 games is Kirby 64, which uses it primarily. I think I may have to put in another stick for c-buttons so I can play Ocarina and Majora's Mask. The problem here is that I really want a stick in the middle- If anyone has suggestions for ways around this, I'm open! :) I am using a traditional BW screen, a 2500 mah battery, and cheap powerboost alternative I found on ebay b/c power-boosts are expensiveeeeee. I know that 2500 mah is small, but I don't need it to last forever. *UPDATE-using a real powerboost now!* I'm using USB audio, trying to get volume control from in retropie so no pot, I have no headphone jack. (I only have Bluetooth headphones, so I don't have a need for a jack) That's basically the whole build! I'll update with pictures and updates later tonight!

Quick update-will add pictures/more info later. I subbed my cheap power-boost for a real one, finished face mods, mounted the holder for my joystick and x/y buttons, cut out the screen, and mounted my USB port, power-boost, screen, speaker, and power/ground rail. Stay tuned! :)

I have Pictures! So far I've
-Done all case mods (except L and R buttons)
-Installed screen and flipped it in software (used HoolyHoo's bracket)
-Glued in x/y/psp joystick bracket
-Glued in psp joystick and wired it up
-Wired controls to Leonardo, used micro-USB adapter to connect to pi
-Stripped and installed Pi
-Installed battery and power-boost
-Installed power switch
-Added power and ground board (homeade)
-Installed speaker
I still have to
-Wire up USB audio (already have board stripped and wires attached)
-Attach all my USB wires and 2 remaining power wires
-Close up the case

Here are some more pictures!

I just finished wiring up and screwing up the case, and realized some of my wiring is causing the pi to be at a power warning. I've identified the problem, and will get to fixing it soon. :)

Err, normally the power warming occurs when your power supply (booster or battery) cannot supply enough current... are you sure this is a cable related issue ?
