Heart Spark jewelry beats to your heart


Heart Spark is a heart-shaped pendant which flashes LEDs in time with your heart beat. A polar chest strap with transmitter (sold separately) is used to measure your heart beat, which is transmitted wirelessly to the pendant. An arduino-compatible circuit captures each beat as it happens and flashes LEDs. Schematics and board layout will be available soon. [via]
