There is a simple idea/thought - The launch monitor you build yourself. Progress, proven.
OpenFlight is a real launch monitor built from a Raspberry Pi and three off-the-shelf radars — about $500 in parts, open source top to bottom. FlightWeb is its cloud: every session uploads itself, and your trends live forever.
An Open-source launch monitor and Cloud... community inspired and built this may be one of the coolest projects I have seen come out in a long time.
