This is a simple way to make the iNecklace light glow any color of the rainbow. In fact, it’s so simple you can change it any time you want in a few minutes. No soldering required!
The iNecklace from the Maker Shed makes a great gift. It's a sophisticated and elegant piece of jewelry with a beautiful pulsating white glow. As beautiful as that white glow is, it's also exactly what I wanted to modify.
