Galileo Live

Galileo Live is a voice-guided physics lab that runs on any phone. Most schools can't afford motion sensors or air tracks, but every student carries a camera. You pick an experiment (a cart on a ramp, free fall) by voice or from the catalog, calibrate the scale by tapping the ends of a ruler, and record a clip of up to 10 seconds. Galileo finds and tracks the object, converts pixels to meters, fits the motion model, and returns the acceleration, its error against theory, and plots of x(t), v(t) and a(t). One tap produces a LaTeX lab report with a generated setup diagram. It works in English and Spanish as an installable PWA, with no special hardware. Built entirely during the hackathon (first commit Oct 27, 2026). Live app: https://galileo-live.vercel.app, i
