I was inspired by the many Game Boy Zero builds on You Tube, but one in particular where the user used an original Game boy cart to house the micro SD card. I give the user props for a good functioning build, but with my ability to design PCBs and some more knowledge about getting hardware working I set out to build my own. My project is all working in prototype form except for the audio at this point because i didn't buy an audio amp board for prototyping.What I did is design a set of custom PCBs to replace the original GB PCBs and clean up the project significantly. Even though i was capable of designing the battery charger and audio amp circuits myself, I took the lazy route and leveraged some readily available designs from Adafruit and copied the Layout and schematics into my project.
Specs,
Original Game Boy DMG-01 Case.
Custom Main PCB
Custom Cart PCB
Custom Button PCB with extra X - Y buttons.
Adafruit 3.2' SPI TFT screen
Mono 2.5W amplifier Circuit
2000mA hour LiPo Battery
Battery Charger circuit
Main PCB
Holds the Pi Zero in a cut out in the middle of the board. Bridges the Connections over to the Cart header for the Mircro SD card. Also bridges the required pins from the GPIO to the screen header. Has Micro USB port for charging. Has USB-A port for external devices. Holds the battery charger circuit and audio amp circuit. I will be using the basic PWM out gpio pin for audio. the audio on these games are pretty crude anyways. The battery connector sticks through one of the openings in the battery compartment with some modification to the opening. I decided not to try to bring out the HDMI port as it would have been very complicated and using a SPI screen the output of the HDMI is the same very low resolution of the built in screen. I am also using the extra GPIO pins for the buttons instead of using a USB device like the teensy. this eliminates the need for a USB hub if you want a USB port on the outside.
Cart PCB
replaces the cart board with a custom board that holds the Micro SD card. Replaces the card edge connector with a female 0.1 pin header. I will post pictures of the board layout software, but the actual implementation will become more clear once I have the boards on monday.
Button PCB
There were existing options for the DMG-01, but they only had A and B buttons, I used the super game girl board at first for prototyping, but it wasnt really designed for the DMG GB even though it was based on the original 2 button PCB--ABXY button pads didn't line up. I decided to make my own board specifically for the DMG GB with the extra X and Y buttons. I am selling the extra boards on Ebay. I received them today and have pictures.

Button Board PCB
To reach the goal of a chiptune/MIDI bluetooth Ukulele we have to :
- Build a playable ukulele
- Make it sound as an original gameboy
- Send it in a bluetooth chip to convert in MIDI
1. Build a playable ukulele :
The idee for this ukulele it's can be build without any modification of the gameboy shell without adding screw or glue.
In this intention I design a neck 3D print in one piece for an easy production and a better sound with standard ukulele tuner which can be found cheap an easly on the net .
The other piece which need to be build is the bridge. After week of trial, I found the best place is in place of START/SELECT buttons. With screw in the actual holes to fix it and supporting the strings tension.
About the strings tension, they are big enought to bend the plastic of the body. To reinforced the body I design a plate to replace the PCB and contercare the tension.
2. Make it sound as an original gameboy
The Game Boy has four sound channels: two square waves with adjustable duty, a programmable wave table, and a noise generator. But a yukulele get 4 string so it can't be use for it.
This audio-processor as all of this vintage console are not product anymore, so the best thing to do is to recreate this sound string by string.
Actual ukulele or other instrument pickup sense all strings at the times and the strings are not in metal, wich reduce the choise for the sensor. After some try I choose IR reflective sensor which are not so expensive and the consumsion are low (20mA each sensors) sun light resistant and with a good string sensibility.
The sound of the string is square-up with a fuzz effect with logic-gate use as amplifier to get the vintage touch and the warm of analogic sound.
All strings square sounds are mixed-up and send via a 2W amplifier to a speaker or headphone wich can be trim by thumbpot potentiometer.
3. Send it in a bluetooth chip to convert in MIDI
The power is provide by 4xAA battery from the original battery.
For the MIDI convertion we need for eache string this dynamic/volume signal and the frequency/note. Each of this signals is provide by the pickup and the fuzz effect wich square up the signal and send it to the ESP32.
Fer bluetooth connextion, I choose the cheap and easy ESP32 and a screen to enter into the menu with the gameboy playable buttons
All of the electronic and sensor will fit in one pcb.
software is not my best, but with the help of the maker community it will be possible!
