Record heartbeat?

I would think that any heartbeat monitor with USB would work fine. I "think" I remember seeing somewhere that a Suunto watch has this capability.

Thanks.

But is was looking DIY project.

it depnds how DIY you want to get, and how accurate you want it to be.

what purpose are you creating this for?

and by DIY, do you mean the hardware or software?

a simple microphone taped to your chest, with a program to log the sound changes and record them as BPMs would qualify.

I mean DIY hardware.

I was looking for sensor and instructions which would get bpm thru mattress or thru sheets during night. This way it is not attached to person.

More times than not, a DIY project like this ultimately ends up costing more time and money than what you can just buy off the shelf...unless you seriously want to play with the hardware needed to make this happen, I suggest you just go and buy an off the shelf sports heart rate monitor that can record and transfer data to a computer via usb...you can find one here for only $75USD...i'm willing to bet that you can't re-create the same functionality for a paultry $75...

Also, if you are wanting to build this little project to monitor someone's heart while they sleep because of a medical condition, I also suggest that you scrap the DIY project and speak to a physician about acquiring the appropriate equipment to do the job properly...

Either way, good luck!
