Josh Petersen’s PiGRRL Zero remix adds audio using the I2S class-D audio amp and a mini metal speaker. He modified the design of the case, making it slightly thicker, and widened the overall length to better fit the gamepad PCBs. In the video above, he talks about his modifications and demos the audio with a play test of Super Mario Advanced.
Fantastic remix, Josh! I really appreciate when folks build on top of our projects and makes them better! That’s what open source hardware is all about =].
This is a modification of the PiGRRL Zero case w/ a couple different modifications. I’ve built three of these handhelds now, and have made some changes that will make the device a much better fit for closure and usability. Here is a list of the tweaks made to the original design for both cases:
Widen both cases horizontally 5mm to allow room for PCB and Adafruit screen/Pi Zero ~ I found that the clearance was tight with the SD card
Deepen top case 2mm to allow for more room internally and proper closure at the top of the cases
Reduce height to PCB screw pegs 0.1mm to make tighter buttons when installing the PCB’s
