This is basic instructions on how to build a portable image projector that uses a green laser instead of normal light. The laser permits images to be cast great distances, and doesn't require focusing - it's always in focus.
This particular design is simple in order, more for the sake of keeping my short attention span on track for long enough to actually get this finished!
Let me know if I've missed some detail and I'll correct it.

Warning: Even a low power laser can cause permanent eye damage
