SIMPLE SEISMOGRAPH STRUCTURE
Eddie Shih
Taiwan
This creation is about a simple seismograph structure. The seismograph is equipped with a universal joint and an infrared transmitter pendulum inside a cover, so that the pendulum can swing with the shaking of the earthquake. The infrared transmitter is kept at a proper distance from a circuit board with several infrared receivers and can receive and communicate information to the AND and NOR gate
