From testing, it seems to require me to press my wrists quite hard against the macbook to get a somewhat accurate reading on the heartbeat. Non the less a cool project and I wasn't even aware my macbook has an accelerometer.

The laptop also contains a normal microphone. You can't access this without root; if you have that you have permissions to access the real microphone.
