Step 7: Button Wiring:
This might look overwhelming at first but it is in fact pretty easy. Just take it step by step.
There are two routes to having your buttons wired:
1. You can buy a ipac controller interface board, which will be a little pricy but it is a lot easier and has more buttons.
2. You can buy two 14 input usb controllers and solder each connection. This is about $30 cheaper if you have a soldering iron and glue gun already. I bought the two Usb game pads at a second hand store for $2 a piece so I went this route.
Soldering up the button interface board:
First you need some wire. I used speaker wire but you can use network cable, or regular wire.
Take apart the usb controller so it looks like the image:
This is very time consuming and requires a steady hand. The connections are very close to each other and you can’t have a wire going across both. But once you are done it feels good.
To make sure the connection works go ahead and plug it into the computer. Then go to start > control panel >devices or game controllers> then click you usb game pad controller. Right click it click game controller settings> click properties. The screen should look like captured image:
When a connection is made it lights up red. If one of the directional buttons is being pushed the axes cross hair will go that direction in the picture above I was pressing left and down at the same time.
I used a spare piece of wood to keep things in order and help make it sturdy you don’t have to do this but it does help.
As you can see once the connection were soldered on, I hot glue gun it into place then stapled the wire down so it wouldn’t move. This allows the wires to be messed with and keeps the soldered joints from breaking off.
Connecting the buttons:
Once the game pads are tested and working. Go ahead and mount them in the arcade cabinet. I mounted mine right under the monitor support piece.
Connect one end of the wire to the ground part of the micro switch and the middle tab. Example image is given:
Then slip the micro switch into the button housing.
Once you connect all you buttons you are ready to go.
Note: don’t worry about connecting the up button with the up joystick micro switch it doesn’t matter when you run an emulator, you choose what button does what function.
