Welcome to my first Instructable!
This hack is a reuse of the old 40 pin SCSI cables.
I was tired of using breadboard space for loading up a bunch of resistors for driving a 128x64 display on microcontroller projects.
It turns out you can use a SCSI hard drive cable for conditioning signals from your device before it gets to the breadboard.
SCSI cables have 2 rows of 20 wire lines running from one of Female Headers to a middle Set of female headers to the other end of female headers. Both rows are accessible at any of the headers.
The 128x64 LCD I am using has 20 lines to attach to my breadboard. I soak up alot of breadboard space conditioning these signal lines with resistors, potenetiometers or capacitors. I decided to use the middle headers of the SCSI cable to add these components in.
Row 1 of one end of the SCSI cable attaches to the breadboard with header pins. Row 2 of the other end attaches to my device, the 128x64 LCD.
I believe this has more potential to make projects more modular, perhaps by adding a small perfboard to the middle header for more conditioning of your data lines.
