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).

- /hardware - An Arduino shield to easily connect a computer PSU and the 6 wires for the large digit driver backpack
This design is OSHW and public domain but you buy me a beer if you use this and we meet someday (Beerware license).
