Hacking Eric Boyd's (http://sensebridge.net) Heart Spark pendant, which pulses LEDs to my heartbeat via my Polar gym chest strap transmitter. I've been experimenting with a proximity sensor to light up the top 3 LEDs on the Heart Spark. It's been very much trial and error to get it to work with various voltage supplies, so far I've tried a 3V coin and a AAA battery with a step up voltage component. It works best as seen with a 4.4V supply from a variable mains adapter. In this video I'm testing it on my Hantek oscilloscope set up on my Ubuntu Eee PC.
