Linux users pop up in the most interesting places, don't they?

In this case, I refer to a group of college students working on an electronic stethoscope that runs on a very small Linux distribution that runs from flash memory.

From their site:

The team is designing an electronic stethoscope that will:

* Record high-quality audio data from a patient's body
* Store this audio data in a convenient format
* Use a USB interface to transfer the audio files to a computer
* Reduce the amount of ambient noise that a doctor hears
* Be simple, accurate, and easy to use!
