Homemade ECG

So I live in New York now. Specifically, I'm in Brooklyn, at least for two months while I work on finding someplace permanent. It's exciting to be in a place where there is so much hacking/tinkering/making activity going on.

I attended a class on Bioelectricty tonight and got to make a do-it-yourself ECK circuit on a breadboard. This screenshot is the bioelectric signals my circuit detected when I stuck three electrodes on my chest.

Very cool, no?

I'm thinking I'll head over to NYC Resistor tomorrow for craft night. I'll probably take my Arduino and see what I come up with.
