A bit old in the blogosphere, but still a goodie, the $500 Thinklabs ds32a Digital Stethoscope comes with a 2GB iPod Nano and special recording attachment that allows you to record the sweet beats of your patient’s heart. The stethoscope technically will work with any recording device that has line-in or mic inputs. However, Thinklabs prefers the iPod Nano because of it’s interface and size.

One warning: Do not connect the stethoscope to a powered laptop or PC, otherwise your patient’s nose might light up.
