EarthquakeLogger
Very simple system I made in ~2.5 days that logs accelerometer (ST LSM9DS1) data over WiFi using an ESP32.
Created in the wake of M5.4 Zagreb earthquake that happened 6 days ago - I'm running this 24/7 logging to a Raspberry Pi in hope of detecting one of the subsequent aftershocks (which has not happened yet).
Still very WIP and bug-ridden.
