Has anyone created a rotating light blocker tube for a fixture before?
I'm trying to create a slow rotating tube within a tube light blocker for a black light fixture I have. The fixture measures 2inches by 2feet and is a fluorescent tube style. I want to be able to have the outer tube rotate around the light, have a slot cut into it so the light can come out but when it's past the light, the hole is blocked by an inner tube so no light escapes. I figure the RPM would be about 2-4. This is for Halloween. The inner tube would be fixed into position and the light fixture be attached to it.
Does any of this make sense? If it does and you know of another project like this, please send me a link.
