[12/14/17] - I was waiting for Helder's practice boards to practice on before moving on. I finally felt confident enough to solder the button PCB to the raspberry pi. I also modified the sound card. It was a challenge getting the headphone jack off, but I managed to do so. I scratched the board a bit but I think it'll be okay. I also glued the bottom down with the L and R buttons.
