I'm familiar with Assembly/C/C++, so this question is focused on the hardware side.
Context: I want to have a real time heart rate monitor so that I can see, on my computer screen, my heart beat. [Want to test biofeedback / controlling of heart rate.]
Now, I know that there are those runner's bands that people wear on their chest that provides an approximate heart rate every minute, and some of them even has a usb port to provide a time series after the fact.
However, I want real time data.
Question: Where can I get (what are these things even called?) a wireless device that can (1) measure my heart rate in real time and (2) broadcast it in wifi or bluetooth .. or anything I can pick up with a PC?
Thanks!

I'm guessing that you want one of these things: TI EZ430-Chronos
Basically it's a watch with an interface for those pulse-rate sensors, and some other type of wireless link to PC's. Oh, and of course you can program the microcontroller in the watch to do whatever you want.
If that didn't get your pulse rate up, here's some more things: 3-axis accelerometer, pressure sensor, temp sensor, 96-segment LCD, and USB dongles for wirelessly connecting to a PC.
The best part, it's available for US$50!
Happy Hacking!
