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