I am in the process of putting together a temporary projector for s show tomorrow since I can't run my big system, and I am having some issues. I have a 532 module that is always in, but has a connector at the front for I think blanking. When I ground one of the pins the beam is off. When I remove from ground beam is on. I need to connect this to my PANGO card, on intensity /Blanking first I tried hooking it up to pin 3 on what I think is the postive on the board, and - to pin 25. Beam was still on. Tried switching, and beam stays off. Does anyone have any safe blanking inverters schematics? (preferably one that I can go to radio shack and build?) also I would like opto Isolation if possible.
ANY help would be greatly appreciated!!!!!!!!!!!!!!!
Thanks!
I have attached a picture of the laser, and board.
