The TCI Seismometer. The TC1 is a vertical seismometer with a natural period of approximately 1 second. Open-source hardware - based on the Arduino Uno - boosts the longer periods in its recordings, so that teleseismic earthquakes are routinely detected, in addition to regional seismic activity.

Seismometers are devices that detect seismic events, usually by mechanically or electronically detecting the movement of a suspended mass. Miniature accelerometers inside smartphones and video games also employ tiny movable masses to detect movements, and even seismic events. My son Eric Mims developed a novel seismometer in high school.

A "seismograph" can be thought of as having three parts: 1 The seismometerwhich senses earth motion, usually producing a weak electrical output. Or more recently, a computer which stores, displays, and analyzes the digitized seismometer output, which incorporates time signals from GPS accurate to 0.

Seismometers are instruments that measure motion in the ground, like the shaking produced by earthquakes. This seismometer is great for the amateur geologist because it is made from a few easy-to-find parts. Its design based on a project found here uses the electromagnet found in a typical audio speaker to mimic a geophonea device that converts ground shaking to a voltage.

A seismometer is an instrument that responds to ground motions, such as caused by earthquakes, volcanic eruptions, and explosions. Seismometers are usually combined with a timing device and a recording device to form a seismograph. Such data is used to locate and characterize earthquakes, and to study the Earth's internal structure.

Created inthe Raspberry Shake is a personal seismograph that can detect local to regional earthquakes. Marketed toward makers and the earthquake-curious, it also has the potential to help professionals increase the station density of seismic monitoring networks. Credit: OSOP.
