Help! Controling light and sound with heart beat

Thanks everybody
I reconsider my project
You'r right, Its to much to do, and I havent got that much time
I wanted to do this myself, just to learn electronics.

So the new idea is to do live performance, where I use step sequencer to create simple beats in my hearts bpm.
what would be the best way to that
This guy did something interesting - Heart Beats for Music Hack Day MIT - YouTube
This would be easy because I wouldn't have to mess with electronics so much.
Is there a way to connect it with abletons master bpm, so that everything I do in ableton would be sync to my heart rate?
Or how difficult it is to make simple drum sequencer in Max/MSP?

Thanks
