Chile: Teen Warns About Earthquakes via Twitter (@AlarmaSismos)

TNW Latin America features the work of 14-year-old Sebastian Alegria (@sebasak), a Chilean teen sending earthquake warnings on Twitter through @AlarmaSismos: “The way it works is ingenious: Sebastian bought a domestic earthquake detector for only $75. He then replaced the internal circuit with an Arduino board which interprets the signal. He proceeded to connect the device to his server. Job done: instead of ringing, the hacked detector was now tweeting!”
