Fireworks Earrings

Of all the articles I have written, it seems that the most popular one was the December 2014 Christmas Earrings project. I received a ton of emails asking me to make other types. I thought it was interesting that the version designed using a microprocessor and surface-mount (SMT) components was far more popular than the simple one using through hole parts.

Since the Fourth of July is coming, I thought this would be the perfect time to introduce some new designs for other holidays and occasions, except this time I would make the earrings adaptable. These new circular versions include fireworks, a Jack o’ lantern for Halloween, and the timeless happy face that can actually change expressions — sad, happy, mischievous, winking, surprised, disapproving, etc ...
