This is the third disc modification I’ve done and it was quite a bit of work.It follows on from the previous modifications I’ve done to the disc which allowed for continuous lighting with a 9V battery.

You’ll need:

about 25 LEDs (3.2V, 20mA) (get more because you’ll burn out a few of them while building)

10 resistors (130 Ohms)


electrical wire

I connected 3 LEDs to a resistor in series, and then connected 6 sets of those in parallel. If you don’t know electronics, don’t try this.

If you’ve done it right you’ll have 2 wires running in concentric circles. For me, the negative was on the inside track and the positive on the outside.

I also wanted this disc to be white and not blue. For that you need to remove the blue plastic wheel around the disc and also the inner “C” ring. Do that by pushing it out from the inside with a screwdriver tip. For the new rim and C ring get some clear plastic PVC tubing from eBay and just glue it in place. I also used snow spray on the inside of the tube to help disperse the light from the LEDs. It would also help to paint the inside of the C ring with white acrylic paint.

After that, connect both circuits up and tape them into each side of the disc. I inserted a switch in there too but didn’t have time to connect it.
