View Thread: Laser Tracking Camera
  • User profile image

    In my last article, we saw how a stepper motor could be controlled with a computer by connecting it to its parallel port. This article will extend it to build laser following camera panner, which tracks and turns towards any laser dot in the camera's field of view. I'm assuming that you have already built a computer controlled stepper motor. If not, go through my previous article for information on how to build one. After you successfully build your laser following camera, you could use your own ideas and creativity to build even cooler things. For example, you could extend this project and build a cool laser following robot, or maybe even an autonomous laser guided turret which shoots down targets you point at!
