Title: Projector Shutter
Post by: Stephen Swaffer on May 03, 2021, 01:00:28 PM
Can anyyone recommend an external projector shutter? Honestly doesn't matter if its dmx controlled or just a hardwired contact closure.

I've searched and found some manufacturers-but few dealers.

Are you interested in a DIY project?

NorthlightDMX has one:

I once made a couple out of tray type computer CD drives. Take everything out of the drive enclosure except the motor and tray. Secure cardboard or black wrap in the tray.
The motor is usually 12VDC, so find a wall wart of sufficient rating and hook up to the motor with a DPDT center off switch (basically reversing polarity to the motor so you can apply power to move the tray in and out). Mount CD drive in front of projector lens. Done.
