Heh heh. The pulse sensor is just a sensor AFAIK. If you want to collect heart rate data, you're going to have to supply a computer, a power supply, and some code at the minimum. For a portable device, I'd look an arduino and something like this ( http://www.adafruit.com/product/1141 ). That'd let you collect heart data over a long time (like, a day or a week). You might need to go to model airplane batteries for your PSU. We did some rough calculations at Freeside yesterday and decided that a 9V battery would last about 4 hours just running the LEDs. The data shield might want more power than the heart LED array does. I configured the sensor to clip to my earlobe, where it seems to be reasonably sensitive and not uncomfortable.
