A few applications of Raspberry Pi were not even in the slightest imaginations of the makers when they were planning to launch a kids programming software. And the most remote thing in that respect was a personal seismograph. The Raspberry Shake recently surpassed all expectations by collecting a fund of $70 000 that is ten times its original amount. The Raspberry Shake is a highly sensitive device that can detect earthquake of 2 magnitude along a radius of 50 miles while the earthquakes of 4 magnitude can be detected across a distance of 300 miles. As per its maker, Angel Rodriguez, the device is capable of detecting movements beyond this range as well however, it would miss out in terms of accuracy.

The core of this equipment is formed by a geophone, a special equipment that turns vibration into voltage. On the inner end of the geophone the coil moves with respect to the magnet leading to formation of current. You can see a better view of this here: https://youtu.be/vBID_tk5Bis
The small sized add-on board improves as well as digitizes the geophone signal and feeds the same to the Raspberry software. The system then time-stamps the collected information and stores it in form of a seismic industry standard format and sends the same in response to client’s requests. These requests are then relayed over screens of systems and smartphones. The complete arrangement is known as seismograph. The makers team behind this creation has been pursuing this task for their living. This one is smaller version of the seismographs Angel’s team has been making for earthquake observers and universities.
We suggest the users to not fall for the small sized and less priced seismographs, Raspberry Shake is better than all those in several respects.
