Fully functional micro arcade machine using a Raspberry Pi model B or B+.
I always wanted a tiny arcade machine for my desk, I decided to build it as small as possible. It may look simple from the outside but a lot of engineering went into building it. After months of development and 8 printed prototypes later, its finally ready. I decided to post the build steps here and links to the 3D printed parts so anyone can build one for themselves.
3D printed parts are available in more colors, check the link below.
Painting instructions are optional, you can paint it anyway you want.
update: added vent holes on the back panel.
1X LED Sequins warm white, pack of 5 (#1758)
Painting supplies (optional)
Start with getting the audio board and speakers out of the Mp3 player case.
I would recommend to test it first and make sure its working before proceeding.
Connect the screen audio board to the raspberry pi
Test all the hardware/software to make sure it works. there are many tutorials and videos online on how to set up emulators on the raspberry pi, the following will cover only the general steps that I did to get it working.
Plug the Raspberry Pi into a monitor for better viewing resolution.
Press ESC and exit to command line. type in (no quotations) "startx" and press enter, this should start the OS which will show a desktop.
Download Retrogame https://github.com/adafruit/Adafruit-Retrogame and copy it on to the Raspberry Pi with a thumb drive.
Extract on the desktop and install Retrogame, (follow the install instructions) this will allow cabinet buttons to connect directly to the GPIO pins on the raspberry pi, instructions can be found here: https://learn.adafruit.com/retro-gaming-with-rasp...
I started with the purple color cabinet, keep in mind its also available in white for custom painting.
If you ordered the white unpolished material, rinse it thoroughly to clean off all the loose powder and dry it with a hair dryer.
Do not separate the buttons yet, leave them attached for easy handling and painting.
The 3D printed parts can be painted anyway you want, its made of nylon, it wont dissolve with alcohol or acetone. You can use pens, markers, acrylic, enamels, car paint, almost anything.
For a smooth surface finish, before painting the case, wet sand the parts first.
Always cover the paint with clear varnish, this will keep the paint protected from repeated handling. Make sure any paint is completely dry before applying any clear varnish this will prevent the paints from reacting with the varnish.
The following steps describe how I made mine:
Keep the push buttons clear of glue in case they need to be replaced, all you need to do is desolder the pins and snap them out from the back.
