Celebrate Valentines Day the Geek way!

This awesome heart shaped PCB is wearable. It has 20 red/white LED's around it's perimeter that blink in a variety of different patterns. It uses an ATTiny45 microcontroller that you can reprogram yourself with an Arduino, if you're so inclined. Has a lapel pin so that you can pin it to your shirt. Uses a CR2032 battery which gives it enough juice to run for 24+ hours nonstop.

Designed for Valentines Day 2013, my first small batch sold out well before that Valentines Day. So I had a much larger batch made and sold several more for Mother's Day. They're available year round now and I don't think I'll run out again. These are great to give to someone you care about, anytime, or on a special occasion like an anniversary or birthday. Mothers, fathers, siblings, girlfriends, boyfriends, fiance's, husbands and wives, life partners. They'd even be great to give to a secret crush. :) Buy a pair, have his and hers, or one for each of your parents.

Includes 2 batteries (per heart) (if shipped to a US customer, no batteries in International Mail, even Canada).

Comes fully assembled and ready to wear!
