Hi Shakers,
Whenever someone talks about “seismographs” it’s common to associate the word with a needle jumping around and scratching the surface of a physical drum. Today, however, seismographs with a physical drum are pretty rare.
Check out our new blog post telling the story of Jon Sammels who became captivated with earthquakes and ended up creating his own physical drum seismograph, and live streaming it along side a couple of Raspberry Shakes on his own YouTube Channel!
