First off i would like to thank rdubbs007 for the easy tutorial!
I wanted led's on top and bottom tho so this is how I did that, keep in mind that my install is less than satisfactory in my opinion only due to the fact that I only had 1/4 watt resistors lying around and i feel they are quite huge for this application and it looks sloppy I think. I will also say sorry for the pic quality I need a new camera and it really shows bad here.
Here is a pic of the top of the nand-x you can see the red wire is getting power for the led's on the bottom of the nand-x you can also see which side is the positive on the led's on top so you know which side to solder the power wire to. Viewing the nand-x so you can read the writing on top, the Left side led's power is on the Right and the Right side led's power is on the Left
Here is a pic of the bottom of the nand-x you can see what I mean by the 1/4 watt resistors are large for this application and would be better with smd or at least 1/8watt also you can see were I got ground for the bottom led's its at the bottom left were the 4 resistors connect also from the top its a hole marked GND on the bottom right.
Here is a pic of the top put back together and illuminated with pink led's
Here is a pic of the bottom put back together and illuminated with green led's
The resistors you use will vary depending on led color you pic but i used 68ohm for the pink on top and 100ohm for the green on bottom and I used 30gauge wire for the power wire from top led to power the bottom led
There is not enough source voltage to run them in series.
I could have run them in parallel and it would have looked cleaner but only having 1/4 resistor on hand it was gonna be ugly anyways so I felt it was easier to wire each one individual and let the leg of the resistor hold the led in place.
