We modified a $40 bathroom scale - leveraging its sensors and swapping out its electronics for ours, to power the ballistocardiograph

Ballistocardiograph: noun "an instrument for recording the movements of the body caused by ejection of blood from the heart at each beat."

Thinking this was extremely cool - and could have implications for non-invasive health care, I teamed up with a friend and turned a bathroom scale into a BCG

 I'm not going to lie, this is one of my personal favorites. You can stand on this scale, wait a minute, and see your heartbeat in a near-equivalent resolution to a $1000+ EKG machine - but for ~$40.

 Here you can see that it is sensitive enough to detect the QRS & TUP heartbeat complexes - the same signals an EKG measures.
