PSP: PiStation Portable

This is my Retropie Portable implementation. I put it together as a design challenge, a chance to learn more about using the Raspberry Pi, and to have a fun hand-held battery-powered gaming console.

My main design goal was to have good ergonomics. This design fits nicely with my large hands, with an analog joystick that I find more comfortable than a D-pad. I really didn't like the feel of the little tactile membrane buttons everyone else is using, so I opted for these nice 16mm illuminated mechanical pushbuttons instead. They have a really smooth action, feel much nicer for prolonged play sessions, and have the additional bonus of being panel mount instead of PCB mount which makes fitting them in the case simpler.

There are only 2 pieces to print with this design. Admittedly, they are large pieces, about 240mm wide. Mechanical assembly is simple, nearly all the electrical parts attach to the case with small self-tapping screws, most of them to the front half with just
