The exposed electronics are cool, but not everyone's idea for jewelry, so I decided to try and do something to make it look better. Of course the first thing I thought of was casting it in a solid block of resin, but that would be difficult to do without breaking the switch and the USB port. I will probably still drown it in hot glue at some point, but in the mean time I simply painted it all black.

The acrylic paint didn't catch very well on the metal parts, so to avoid "dirty" look I just scraped it completely off them.
