GLPA Workshop - A Simple and Programmable Lens Shutter for Your LCD Projector

  • presented by Dave DeRemer

LCD projectors are portable, relatively inexpensive and quite handy for PowerPoints or video segments during programs. The main-concern, however, is that when there is no video section showing, the LCD projectors leave an annoying large gray rectangle on the dome. Our solution is not really unique or innovative, but it works! With a special geared motor, a transformer and a light baffle, you can create your own LCD video shutter.
