Heart Spark necklace shows the beating of your heart

Here’s an interesting bit of jewelry. Yes, I know, jewelry doesn’t generally seem like something that belongs on here, but bear with me. This circuit board shaped like a heart does more than just look geeky. It also features a set of LEDs that will blink. What’s cool is that the blinking can be set to match the rhythm of your heartbeat. Then everyone around you can see the beating of your heart.

The downside to this Heart Spark is that you actually have to wear a separate strap that reads your heartbeat and wirelessly transmits the information to the necklace. Really, what could be a more touching gift to your significant other than a necklace that shows the beating of their heart? Of course, they’ll never be able to hide anything from you, as you’ll see when their heartbeat starts to race. The necklace itself will set you back around $70, but the monitoring strap will have to be purchased separately for around $40.
