The whole thing hooked up



In the images below you can see how the keypad has been connected.  All the headers from the switches have been plugged into the PCB and the PCB cable is attached to the 10pin keypad header (as seen in the second image).  The GPO controlled LED's have been connected independently of the PCB and I have used spiral wrap to make the cables neater...





You can see how I have used heat shrink sleeving wherever I soldered and where short circuits could happen...

Yea yea, the DVD drive will get the work over when I got some spare time,
and I'm waiting for the replaced CDRW drive to return...

LCDC, what on Mars is that?

Thank you!!

I would like to thank the following people that helped make this 'mod' possible. Listed in no particular order....

  • The many peeps at BiT-Tech, HardOCP, ZapWizard, AW3K, Cheese, and Rob Arnold for the inspiration...

  • Chris Cotton, for his metal cutting skillz...

  • Gary Cho of CustomPCB for the great service in getting the PCB to me!

  • Henry, Adam and all of MatrixOrbital for making such fine displays!

  • The author of LCDC, simply the BEST display software...

VFD Lovin'!

I realized at the end of all this planning, that the LCD does not look 'brilliant' when mounted in the front of my case, but due to the beauty of my 'keypad PCB' I was able to apply it to the VK204-25-V VFD Module (shown below), just the same way!  Of course the LCD will find a spot inside the case...



Notice the trademark display controlling circuitry on the rear of this Noritake display!
