Light trap
    #610688 - 02/26/12 03:44 PM (12 years, 1 month ago)

I need some advice as to how to let in air, but exclude light. I must not be searching right. Can anyone point me in the right direction?

So you're trying to built a dark room with ventilation and can't find anything?

I want to pull air through a vent in a box and into a filter. I want to be able to turn on the lights in the room anytime I want and know that I'm not disturbing the light cycle in the box. I want the vent to let no light in and let air in.

Well you just put a couple of right angle bends in the tubing.  Pretty simple.  You must baffled.

I tried that by constructing something like a periscope without mirrors. While greatly reducing the light from a flashlight, 2, 90 degree turns didn't eliminate all light. Think I'll add another turn and try again.
