This programmed pendant flashes its lights to the beat of your heart.
The Sensebridge team in San Francisco created this necklace, the Heart Spark. The LED lights flash all around the necklace circuit board.
The necklace has 3 different necklace options or you can just get your own. Sensebridge will soon have the schematics, layout and software so the nerd in you can come out and create this yourself. Or, you can go and buy this awesome circuit board pendant. Heart Spark.
