Case for Papilio Duo FPGA and LCD Projects

thingiverse

This is a straightforward instance that encloses the Papilio Duo FPGA board, 7" LCD screen, and analog joystick. I utilized it for a Mandelbrot fractal explorer project. The SketchUp file is available if anyone wishes to customize it for their own Papilio Duo project, such as a Papilio Arcade project, or even a project using another board like a Raspberry Pi. A short YouTube video of my fractal project with this case can be seen here: https://youtu.be/OqxMnT_Ruuk. The text in the YouTube link contains more information about this FPGA project:https://github.com/elkayem/Mandelbrot-Explorer A few details on the hardware: The mounting hole pattern is designed specifically for the Papilio Duo, and it mounts with M2 nylon bolts. It can be easily modified in SketchUp to mount a different board (e.g., other Papilio boards, Arduino, Raspberry Pi, Beaglebone, etc). The LCD mount fits a 7" LCD screen with display driver board. The one I used can be found by searching "7 inch 1024*600 TFT LCD Display Driver Board HDMI VGA 2AV for Raspberry Pi" on eBay. A picture of the one I used is included. The case design includes a mount for the display driver on the back of the LCD screen, using M2 nylon bolts. A mount is included for a PS2 style analog joystick. There are many joystick modules available with slightly different hole patterns. An image of the one I used is included, which can be found at all the usual sources for a few dollars. Search for "joystick module arduino" and you should be able to find this one. Or modify the SketchUp for your own module. My project required two buttons and rotary encoder, all of which required a 6mm diameter hole. Your own project may require something different. The hole placement and size can easily be modified in SketchUp. The top and bottom of this case attach together using M3 standoffs. I used two 30mm male/female brass standoffs connected together. I intentionally did not raise the walls of the case all the way so I could easily access the electronics inside while the case is closed. Again, the walls can easily be raised in SketchUp if you desire a sealed case. Hopefully someone finds this all useful. It's a pretty specific application, but the design can be modified to suit your own project's needs.
