DIY An Arcade Table(2)


The previously prepared stereo speaker has come into use. Now I want to transplant the speaker into the table. In fact, there is nothing special about these tasks, that is, they need an extension cable and then output it through the 3.5mm audio jack of Raspberry Pi. Drill holes on both sides of the table and drill holes (10mm) at the edge of the table to place a volume controller. Then fix it with hot glue.

Remove the volume control section of the speaker and set it aside.

Making extension wire by welding

Drill a hole in the edge of the table to place the volume controller.

Mark the installation position of the speakers.

These holes are drilled mainly to hear the sound in the future and then fix the previous speaker and volume controller.


I plan to put the battery into the table. I put the connector into the bottom of the table and then use the extension cable to extend the power cord. Of course, we have connected the Raspberry Pi with the speaker before to deal with the signal problem. It is worth noting that I am wiring under the table here.


Make room for the power supply and connect the IEC connector to the power supply.

It is now possible to weld IEC connectors and power supplies and then install them.


After fixing the screws on the power supply at the bottom of the table, try to tighten the screws.

In this way, the Raspberry Pi, USB adapter and screen can be installed together. Of course, a power cord can supply the power.

Last modification

The most important thing here is the display screen. Acrylic materials are used here. Cut them into 550mm x 550mm thin sheets and pad them at the four corners. I also reserved a USB port on the side of the table for Raspberry Pi so that I could connect the keyboard when I needed it.

Connecting this to the Raspberry Pi can also be connected to the external port through it which can be regarded as a dust-proof effect.

If you follow the previous steps to protect the monitor, I have added plastic to protect the table. At this time, do not forget to remove them.

The previous thread opening is a little big. Cut a part of the scrap board and cover it.

Finally, install Retropie in the SD card. Then you need to coppy files with ELF suffix(start.elf, start\u cd.elf, start\u db.elf, and start\u x.elf) are copied to the SD card. of course, also NOOBs.
