SparkFun Speed Trap
This is a project demonstrating how to display instantaneous speed from a LIDAR on two large 7-segment displays.
Note the handprints on the wall...
The new LIDAR-Lite from PulsedLight is pretty nice. It outputs readings very quickly. From multiple distance readings we can calculate speed (velocity is the derivative of position).
