Note: This will only work for devices that are A. under 12volts. B. 10/100.

  This will NOT work with gigabit devices and support full gigabit speeds.
  Gigabit requires all 8 pairs to work properly. 

Pin 1 <-> data (Orange-White)
Pin 2 <-> data (Orange)
Pin 3 <-> data (Green-White)
Pin 4 <-> DC +Positive Wire 1 (Blue)
Pin 5 <-> DC +Positive Wire 2 (Blue-White)
Pin 6 <-> data (Green)
Pin 7 <-> DC -Negative Wire 1 (Brown-White)
Pin 8 <-> DC -Negative Wire 2 (Brown)

Here I will describe how to make your own parallel to LCD circuit. It is a fairly simple process.
I have also included a schematic of the circuit, I will explain how to read the schematic.

  This works for me to supply a un-regulated 12v and 5v line, along with 2 grounds.
  Be carefull with this one, and/or include a fuse so you don't smoke your cpu power
  supply if you 'accidentally' pull to much juice.. Have phun..

 Here is a schematic to the un-buffered ISP programmer I use for programming my ATMega8 microcontrollers.
 Seem's to work well with AVRDude on Linux, I have not tried many others, though net resource's it seem's
 to be compatible with most software for writing to the chips.
