Step 11Final Light Up Smiley Face and more ideas...
Some ideas I have to to improve and extend this project are:
Add a sliding switch on the wood and connect it to the unit so you don't have to plug and unplug the Light Up Smiley Face. (If you were looking closely, the switch was in my original design. I just need to find one to add.)
Or...
Drill small holes in the CD and put the IC board behind the CD for more light reflection. This would be really time consuming and would require a different design (to fit around the CD), but the light effect could be really neat.
