  1. Can this laser “flower” effect (not the actual playing) be copied by using a flashing laser beaming on a rotating mirror? If you would regulate the pause between the flashes?

    1. Well, just read through his project log.
      He is using a (omnidirectional) light intensity sensor to measure if there is a reflecting object within the ray.
      As the laser ray are generated one after each other over time, one sensor is enough for any number of “harp-strings”.

    1. I think the webcam would just make it super hard (with the vision system software) Plus the rotating mirror would interact with the framerate, unless you synchronize the motor to the webcam framerate (how would you even know when the webcam begins a new frame?).

      1. Alternating black and white marks on the mirror shaft, then program the camera to ignore frames where there isn’t a white stripe in a specific part of the picture?
