How can I make a small TV using a small LCD screen?
I have a movie project idea that requires the use of a prop with one heck of a twist. Im trying to make a "Crystal Ball" that can project a movie from the inside of the ball, and I need to find some way to make it work without the necessary use of any tv or usb cables, even though it can use them. (Ex: in one shot, the actor is holding the ball, and is visible from head to his waist, but there are no cables running from the ball) So it could use video data from an SD card or a USB and also be used as a TV. The largest ball I can find is a 3" diameter clear plastic craft ball from a nearby hobby shop in a neighboring town. I guess what im asking in a nutshell is "how small can you make a diy projector?" Any help with this will be greatly appreciated!
