Video projectors are great. They can easily produce a very large image to watch. With that large image comes a large screen, and who wants to look at a large screen when not watching TV? Well, [Steve] didn’t either so he set out to make a powered retractable screen for his projector. The best part about this one is that it is done in true DIY/hacker fashion. The parts used are definitely not intended to be used as anything close to a projector screen and the overall cost is kept to an absolute minimum.
The business end of this project is an electric screwdriver. It is mounted to a shelf that’s sole intent is to support the contraption. The screen rolls around a standard cardboard tube. A screwdriver bit, wooden dowel, bronze bushing and water pipe fitting are responsible for connecting the drill to the cardboard tube. Holding the bronze bushing in place is a clip that is intended for broom handles and the like. The whole thing is covered up by a cornice to hide the hackery.
To raise and lower the screen, [Steve] has to reach up and manually push buttons on the screwdriver. In the future we’d like to see a wired or IR remote to control the screen so it can be raised and lowered from the comfort of the couch.
