This is a ceiling mount I built for myself using some hardware, aluminum, delrin and some of my design and machining skills. My dad did some welding to weld the tube to a swivel plate toward the top. it features variable "pitch" and "yaw" adjustments just by swiveling it by hand with a small amount of force. I have friction material similar to Nylon in which is tensioned "just right" to my taste to hold the position. "roll" adjustment must be done by adjusting screw tension to the ceiling or shim plates. So far, it seems to be a very stable mount, it doesn't seem to wobble or sway.
One thing that might be considered interesting about this design is that I can remove the projector by taking out two thumb screws that lock a mount plate into place. The third and fourth picture illustrate this feature. The plate mounted on the projector itself has two slides that ride on the small square plate hanging from the ceiling, and those slides have thumbscrews in which to lock into conical impressions drilled into the plate that it mounts to on the ceileing part. A hope was to use this as a "quick release" so I can work on the unit or use it somewhere else.
The projector is an NEC MT-1040, or MT1040. It is an XGA resolution LCD unit rated for about 1300 lumens. I will admit that it doesn't have a spectacular black level, I wanted to avoid "rainbowing" in my first foray into the projection, so I avoided DLP units for now. I am willing to try out CRT, DLP and LCOS units at some point in the future, and I believe that this mount should accomodate the weight of a CRT as I've found that it can support my own weight when I try to hang from it.
The camera used was an old Sony Mavica FD-73. The images are not a totally accurate capture of the actual environment.
