Raspberry Pi Desktop Retropie Arcade & 7" Screen

This is a desktop arcade measuring 200mm wide and about 180mm deep.

It is meant to use arcade parts and a raspberry pi 3 or compatible board.

There's access to the SD card along the right side.

#Instructions

First off mount the raspberry pi, the buttons and speakers in the panels. Once this is done you can mount the USB header and power supply.

I just drilled holes to mount the power supply and USB button controller in the case. Due to the millions of options for these out there there are no hole or bosses included.

Once the parts are mounted you can snap the screen into the bezel and mount the circuit boards for it. I found the USB Power cord way too large on mine so soldered the power wires right to the back of the plug on the board to save space.

Install Retropie on your SD card, put ROMs in and go! See Retropie's website for details:

#Parts List

• Raspberry Pi 3 B+
• USB Game Encoder
• 24mm Arcade buttons
• Dual USB Panel Mount
• Hook-up wire
• 32GB SD Card
• 7 in non-touch screen
• IEC power inlet with switch
• Short HDMI Cable
• A decent 5v 5amp power supply
• 16mm power Button
• M3x10mm screws
• Stereo Amp
• 40mm Speakers
• Arcade stick
• 2 x 40mm 5v fans, I used good ones for quiet performance.

This is what I bought and what I am designing it around. You don't have to buy the same but do know this is what I used.

So far the screen slides into snaps on the back and the front button panel is hinged. When you install the speaker cover it ties it all together securely.

I used hot glue to secure the screen in the frame and superglue to attach the speakers. The buttons have cutouts in the back so they can snap in easy.

#Updates

• 12/12/18 Worked on it all day and uploaded the progress. At this point it's 90% complete. All the listed parts have been ordered and printing will begin this weekend once I can confirm the screen layout.

• 12/15/18 Got most of the parts in today and decided to go ahead and change the design to make assembly easier. The whole front panel now is attached to the button panel making access much easier. Unit still goes together on the main body with just 6 screws. All files updated!

• Update 2! It's now in line to be printed. I have all the parts and the STLs have been edited. I added a 6 button center panel for MAME style games. The extra 3 buttons give you coin, player 1, player 2 for true arcade style gaming using small push buttons like https://www.amazon.com/gp/product/B0119FH5Z2

• 12/16/18 Printed some of the parts and making minor tweaks. Changed the speaker surround size and made it taller for easy gluing. I am building mine with MAME buttons so I can attach the MODE of the USB arcade controller to one of them. Edited the mount for the audio amp and volume knob.

Edited the screen hood so the standoff for the board are positioned so the board can be glued to it. This way many boards fit and fit more reliably.

• 12/23/18 Updated all files! Machine is built and working great. Made some slight design changes to make assembly easier.

• 12/27/18 All files updated and ready to go. Test prints and first unit came out perfect.

• 3/12/19 Updated parts list and instructions.
