PALZero

thingiverse

With plenty of love shown for the North American SNES for raspberry pi cases and the more aesthetically appealing (imo) PAL version being left behind, I decided to model one to suit a Pi-zero with working buttons and front facing USB ports. It's a very easy print but requires some soldering for the USB ports and network card to work. I have written a draft guide for this, but made a mistake with the GPIO wiring for the buttons. I aim to update this soon. In the meantime, here are the steps to follow: First, assemble the case by snapping in the USB/LAN hub and securing it with glue. Next, trim the excess PCB on these hubs to fit properly. The LED wires can be soldered to the PiZero on the 5v and GPIO pin, routed up through the bottom to keep the top from getting cluttered. Make sure these wires are snug against the PCB with as little exposed wire as possible. The first button soldered in is followed by the second button. The buttons can then be screwed into the button mount. Button caps added, I added a drop of glue to the top of the buttons to keep them from rattling around. The faux cartridge slot can be glued in place from the inside. Test fit of the buttons shows my case is a bit rough on the inside from the printed supports. Happy with the fit-up, I glued it in place. The HDMI adapter and power cable can be placed in their slots. A craft knife was used to make a tiny bit more room before gluing it in place. The SD card can be prepared with RetroPie now, everything needed for this can be found here: https://github.com/retropie/retropie-setup/wiki/First-Installation Assembly all done, time to program the buttons and LED. Guide for this will be uploaded soon. Here are some additional details that were not included in the original guide: * The LED needs a 270Ω resistor wired to the 5v wire and then covered in heat shrink. * I used black heat shrink on the 10KΩ resistor and made a note of it so I don’t get them mixed up. * Just labeling the wires so I remember which resistor is which. * The power switch can be fed through the top of the switch mount and secured in place with glue after connecting it to the ground wire on the power supply USB cable. * A dab of epoxy was used to hold it in place. * Trim the LED wires to length, about 75mm will do.
