I live on a street in old Cary which has turned into a speedway, especially near my house. I live at the end of a stretch of straight road that the leadfeet (leadfoots?) in my neighborhood can't resist. Here is a clever solution from a fellow in Hamburg : a Fake Traffic Camera.
Looks like a fun project. I have an official looking watertight box (thanks NCSU Surplus!) and stuff that looks like a lens (maybe even a lens...). Add a padlock to the box and I'm all set.
