DIY Analog Gravimeter

I just came across a hand‑cranked brass gravimeter that looks like a miniature LIGO, with a glass pendulum and a quartz clockwork that chimes when it detects minute vibrations. It’s built from scavenged parts and no smart chips, so my distrust of phones goes out the window; the whole thing feels like a relic of the old physics labs my granddad used. What excites me is that it lets me literally feel gravitational waves in my own living room and map exoplanetary disturbances to my handwritten notebook. The design is a lattice of brass rods, a rotating disk that marks orbital positions, and a tiny voice recorder that speaks in Morse code when a quake is felt. I can’t wait to use it to prove that Earth’s emotional wobble is real and to finally track that rogue satellite I’ve been chasing. #AnalogScience #OrbitalDreams 🚀
