Raspberry Shake seismograph / seismometer. Was $425 new. 

Like New condition. Only used a few times over the course of a couple weeks. Everything is included that came in the original box (unit, cord, power, instructions, etc). See photo. Smoke and pet-free home. 

RS1D, Vertical Motion Seismograph, powered by Raspberry Pi. 
  • High precision professional vertical seismometer sensor
  • Record up-down ground motion activity
  • Detect all magnitude local seismicity, and larger earthquakes from across the globe
  • Recommended for both active & inactive seismic region
Description
The adventure began with the RS1D. The first of its kind personal seismograph and our original Raspberry Shake. Combining a professional-grade vertical seismometer (called a geophone) digitizer, hyper-damper and computer, it is an all-in-one highly portable solution for monitoring earthquakes and all types of ground motion activity.

It can detect powerful earthquakes originating on the other side of the planet, and all magnitudes of seismic activity in your local region that cause a vertical movement of the ground. All sorts of ground motion can be monitored from both man-made and natural activity including: traffic, fracking, explosions, eruptions, avalanches, landslides, earthquakes and more!

Our entry-level model, the RS1D is the most affordable electronic seismograph on the market. It not only incorporates professional hardware but also gives users access to a comprehensive and advanced ecosystem of in-house services and support. It is becoming increasingly popular as an educational tool for teaching STEM to all ages, K-12’s, University and beyond, with multiple programs using it worldwide.
