Document cameras are expensive and don't have the field of view I was looking for. One day, looking at the back of the LCD projector I noticed it had a video input... This led me to my old digital camera that had a video output!
What you will need:
1. Digital camera with video output
2. LCD projector with video input mounted to ceiling
3. Cable to connect the two (1/8" mini jack to RCA)
4. Lots of batteries for the digital camera (if you have a plug... all the better)
5. 1/4-20 bolt/machine screw 0.5"-0.75" long
6. Three old yardsticks
7. Metal piece with 90 degree bend or the like
8. Pop riveter & rivets or equivalent
*(this is only a cheap document camera... if you already have the LCD projector)
Step 1: Camera mount:
The digital camera needs to aim at the work area to show what you are doing and be up enough to not get in your way or bonk your head. So I needed to hang it from the ceiling. The first time I did this the pole, from ceiling to camera, was to short... then I lengthened it.
