Still on the test bench. Have tested laser pointer module and solar cell about 6 meter apart so this should work. Now I need lots of cable...
I still want to use a reflector so I can have all electronics on one side of the road and just a reflex, mirror or something on the other side.
Now one laser pointer is more of a laser lamp. The point is about 5x5 cm at 6m distance. May need to change it.
