Stock disc set before:

After custom mod:

How I did it:
I started by taking the disc apart, removing everything and cutting out the black plastic backing behind the C ring.


The plastic rings have a blue tint to them, just like the toy but with enough light it's a pretty light blue so I decided to leave them, besides I didn't want to deal with casting new rings.

First I tried some front firing LEDs, but they were actually too bright!

They were also too thick to fit in the compartment and still allow room for the discs.

So I went with two separate SMD strips, 21 diodes on each strand mounted back to back so it would fire around the outside of the disc and towards the center to illuminate the C ring and the TRON logo in the middle.

The next obstacle was figuring out how to get enough power to the SMDs in a small enough space to fit inside the compartment. An A23 12v battery did the trick. I removed the existing battery compartment so I could access the new battery from the same door.



I also drilled 4 holes in it for the holographic projectors. I wasn't too crazy about the stand it came with since it blocked off part of the outer ring so I modified two of the stands that came with the deluxe disc toys and combined them to make a new one.
