SF Did you try <a href="https://raspberryshake.org" target="_blank">https://raspberryshake.org</a>/ ?That site seems very commercial to me.I helped set up a seismometer at a K-8 school a few years ago with an educational group that did the same thing but more science and less sales. <a href="https://www.iris.edu/hq/sis" target="_blank">https://www.iris.edu/hq/sis</a>You will find the Raspberry Shake alongside many others that are both build-it-yourself and commercial.Raspberry Pis are great! I have 5 or 6. But you could reuse virtually any old PC lying around for this application.  As other people here have said, Pis are hard to get right now. Please don't give in to the greedy scalpers charging many times the list price! Don't let it stand in the way of science and learning. Get started by reusing old or alternative equipment. (For example the "Libre Le Potato" looks good at $35 (Yes that's its name!)
