[Vik] sent in this easy little project. He purchased a $3 spy ear, a easy 3 transistor amplifier, and attached a stethoscope end. little modification was necessary, primarily just scraping a bit much more space in the microphone tube. The end result is a very cheap electronic stethascope that can be hooked to a computer or other speakers for multiple people to listen to.
