https://stream.echo6.co/videos/watch/933d275c-95a8-4c79-b4dd-f20008ba1d47 Laser range sensors can measure long distances with high precision. Today we try to build not only such a range sensor. We want to use it also as laser speed gun. Will it better than our radar sensor? In video #181 we tried to measure speed using a cheap radar sensor. This project is still in the lab, and I expect an update in the next month or so. In the meantime, I started experimenting with another technology we already encountered in video #119: Time of Flight sensors used in LIDAR systems. This was one of my longtime wishes, and it became reachable when I saw these new rangefinder modules pop up on AliExpress. They have no display but a digital interface. Exactly what we need for our hack.
