Raspberry Shake began making simple but highly-accurate seismographs for use by students and citizen scientists. The Raspberry Shake 1D used a single, vertically-oriented geophone for detecting earthquake activity. The company then responded, with the Raspberry Shake 3D, to demand for a professional-grade seismograph that could detect earth motion in all directions. The third iteration, Raspberry Shake 4D, by popular demand, went back to a single, vertical geophone but added three accelerometers oriented to detect motion in all directions. The 4D model meets standards for seismic monitoring on construction sites. The latest offering, the Raspberry Boom, measures infrasonic atmospheric noises coming from volcanoes, meteors, aurora, wind farms, breaking icebergs, and more. OSOP, a company that develops early warning civil defense systems for natural disasters, launched the Kickstarter campaign for the Raspberry Shake, and now it’s doing the same for the Raspberry Boom. Some assembly and connectivity are required.
