OpenFlight

About

An open-source golf launch monitor built from a Raspberry Pi 5 and off-the-shelf Doppler radars for roughly $500 in parts, where commercial units run into the thousands. A sound trigger catches impact and the radar I/Q data is analysed in Python to derive ball speed, club speed, smash factor, launch angle, club path, spin rate and estimated carry. Sessions sync to FlightWeb, the project's hosted dashboard for shot history and dispersion trends, and raw radar data never leaves the Pi — only shot summaries are uploaded.
