Back in the 1960s, kids didn't have Halo 3 or Madden NFL 2007 to entertain them. Even PacMan hadn't been invented yet. But that didn't mean there weren't any electronic games. One of the first was called Operation, and it challenged players to remove tiny plastic game pieces from the body of a nervous patient, who the game creators called "Cavity Sam." Players earned game money by performing various operations on Sam, but one false move would cause a buzzer to sound and Sam's nose to light up, signaling that the surgery had been botched. After 40 years, the original Operation game is still on the market, and Hasbro recently introduced a new Simpson's edition, with Homer as the patient (Figure).
In this project, you will build your own Operation game from foam board, wire, and basic electronic components, including a buzzer and an LED. In Challenge 1, you will set up the game board. In Challenge 2, you will make the electrical connections and try your hand at performing operations on your patient!
