The first side of the keyboard had been wired, it was time to start on the second side. Of course, the buttons have not been installed, but the sign on the back of the PCBs says, "SOLDER SWITCHES LAST," which is there for a good reason. PCBs from the first side were fastened in place with wood screws.
An ordinary 4-conductor coiled phone cord was salvaged for this project to become the connecting wire between the halves of the board. Phone cord is ideal because it can be ordered inexpensively, it is still a common commodity because of the prevelance of VOIP phones, the coiled wire is great for a flexible out-of-the-way cable which looks nice. Coiled USB cables can also be used in this case used if they have all four conductors. One end was bulked up with electrical tape so it would stay secure inside a nylon wire strap. 6.35mm (1/4") straps were used. They are a common item for running television cabling.

Fastening the boards to the wooden platform
An ordinary 4-conductor coiled phone cord was salvaged for this project to become the connecting wire between the halves of the board. Phone cord is ideal because it can be ordered inexpensively, it is still a common commodity because of the prevelance of VOIP phones, the coiled wire is great for a flexible out-of-the-way cable which looks nice. Coiled USB cables can also be used in this case used if they have all four conductors. One end was bulked up with electrical tape so it would stay secure inside a nylon wire strap. 6.35mm (1/4") straps were used. They are a common item for running television cabling.
Coiled phone cord attached to one side of the keyboard
The second side of the keyboard was attached in much the same way. Each wire was assigned to a specific pin. In this example, the white wire was Vcc, the pink wire was SDA, the blue wire was SCL, and the yellow wire was GND. In the same way that the first board to be wired was a 1x4, the second half also connected to a 1x4. Since the data lines were meant to be in parallel, it didn't matter where I tapped off the data and power pins, in this case, they came directly from the controller.
