Folks go way fast on my street. I would like to (INEXPENSIVELY <$100) make a way to make a “speed trap” to find out just how fast these cars are going and go visit with the specific perpetrators and show them the data.
I assume I could set up some type of sensors that would get the front of the vehicle at point A, measure time to point B where another sensor picks up the vehicle. Nothing perfect, because I can go buy a hand held device for just under $100.
I have an Arduino Mega board, I have a couple Propeller Dev boards.
What should I use for sensors…daytime use? Street is about 20 feet wide, I haven’t measured.
Any pre-existing C, C++, or Spin programs out there already made for this that I could modify? I guess biggest cost would be the sensors, right? Part numbers would be really awesome too.
