Mini SNES Pi Zero w/ Functional Switches

thingiverse

This is a build guide for a RetroPie project, specifically a mini retro game console using an Raspberry Pi Zero. The text describes in detail how to assemble and wire the components together, including the power switch, reset switch, USB ports, and LED indicator. Here are some key points from the guide: 1. **Surface Preparation**: The surfaces of the switches and keys need to be sanded smooth for proper operation. 2. **Spring Insertion**: The pen spring is inserted into its designated slot on the perfboard. 3. **Power Switch Assembly**: The Power switch can be attached directly using a #4-3/8'' screw. The spring and Reset switch should look like this, with the spring pushing the switch back into place. 4. **Reset Switch Testing**: Test the functionality of the Top switches by inserting them into the bottom shell and checking that they move up and down smoothly. 5. **Component Placement**: Follow the diagram to populate the perfboard with the USB connectors, tact switch, and mounting screw. The placement of these components is critical for everything to line up properly. 6. **Wiring**: Use a diagram to refer to when wiring all the components together. The power switch is connected between the Pi and the barrel jack, the reset switch is connected to GND and GPIO3 on the Pi, and the LED is soldered to the 3.3V pin and GND on the Pi. 7. **Power LED Assembly**: Apply heat shrink tubing to the LED, solder a resistor and some length of wire to it, and test fit it in the case. 8. **Final Assembly**: Line up the power switches, screw the top and bottom shells together, paint the Eject panel and controller ports a dark grey, and enjoy your new retro gaming system! This guide provides detailed instructions for building a Raspberry Pi-based retro game console using a RetroPie installation. It covers assembly of the components, wiring, and final assembly to create a working console.
