New Updated with sound and more mods with ATX power supply
About a year ago, I mod my Arcade1UP Street fighter machine with the Raspberry Pi and RetroPie. It worked great and fun.
Now, I’d complete the project with more mods. The new mods include a Logitech Speakers, old PC power supply (which I have it laying around in my house), an ATX breakout adapter to provide 5V and 12V power to the system. I also added a powered USB hub so that the LED buttons draw power from the USB hub instead of the Raspberry Pi.
- ATX power supply (if you do not have one laying around, you can get one cheap from Amazon)
- ATX power supply breakout adapter
- Wire terminal connectors (We need the 0 shape terminal)
- Wire cutter, stripper and crimper (That is what I use)
- Logitech Multimedia 2.1 Speakers
- Powered USB hub (My black USB hub was a gift from someone, but the one in the link should work)
- Thin wood board for mounting all the devices
Let's get started
1. Cut the cord
First, disconnect the power connector from the power adapter shipped with the Arcade1Up to the Display Controller.
Cut the end of the of the power adapter and crimp the round circle terminals to the wire of the section where the plug is.
The outside of the plug is negative while the inner part is positive.
2. Connect cords to the Breakout adapter
Connect the newly create power cable to the ATX power supply breakout adapter +12V terminal. Make sure Positive of the o ring terminal adapter connects to the Positive of the +12V terminal and the Negative connects to the Negative.
Test it with the multi-meter and make sure it is 12V and the polarity is correct.
Cut a microUSB cable and crimp the o ring terminals to the Red (+5) and Black (-) wire.
Connect the microUSB cable to the ATX breakout adapter +5 terminals. Measure the voltage like what we did with the +12. If everything looks good, you can test it with Raspberry Pi and ATX power supply. ( I tested mine with a old 1st gen Raspberry Pi. The one I used for the Aracde1Up is a Raspberry Pi3)
3. Connect the Power Switch
The ATX breakout adapter has a power switch on board. We are going to connect the wires from the pins of the breakout adapter power switch to the Aracde1Up Power switch so that we can power on and off the whole machine by cutting the power to the entire breakout adapter.
So let’s remove the power switch and volume switch assembly from the Arcade1Up control panel. In addition, remove the Volume switch complete from the assembly.
Connect the wires from the bottom of the breakout adapter power switch to the Aracde1Up power switch as shown in the photo.
Mount them on the thin wood board. I also added a powered USB hub for the Arcade Joystick and LED buttons. I connect a regular USB to MicroUSB cable from the ATX breakout adatper to the USB hub.
Now you can place the wood board at the bottom of the Arcade1Up machine. Then put the Arcade1Up power switch back to the control panel where the Joystick and Buttons are located.
4. Add the external speaker
For the Logitech Speakers system. First, lets remove the screws of the sound power and volume module and then remove the electronic part from the plastic box follow by disconnect the wires from the electronic board.
Connect the 12V adapter we made earlier from the ATX breakout adapter to the Display Controller
Fish the speaker power/volume cable through the Arcade1Up original Volume button hole. Connects the circuit board back to the connectors and put it back in the plastic box.
With that, you can now control the Raspberry Pi
5. Connects all wires and secure the devices
Install the Sub woofer of the Logitech speaker to the bottom of the Arcade1Up next to the Wood board as shown in the photo below (the black box on the right).
I used a double foam tape as well as couple small wood screws to secure the ATX power supply to the bottom of the Arcade1Up machine as well.
Connects the rest of the cables including the USB Arcade Joystick cables to the USB hub.
Connects the speaker mini jack to the Raspberry Pi
6. Mount the external speakers
Mount the 2 speakers on the Aracde1Up machine. (I use doubled sided foam tape to mount them)
7. Connect the power
Cut an opening at the back of the Arcade1Up machine to for the speaker power cable and the ATX power supply.
Connects a power cord to the ATX power supply and plug them to a power outlet.
(Note: the 3rd cable in the photo is my Wired Keyboard cable)
