Step 8Shine some LASER light on the mirror
WARNING: LASERS ARE NOT TOYS!
Make sure you do not point them at yourself or your friends. With reflections the path of the laser can be somewhat unpredictable. Always be careful, you can seriously damage your eyes even with low power lasers!
Keeping this in mind, take the laser pointer in your hand and shine it on the mirror, so it bounces off it and hits the wall. The spot will dance around as the mirror wiggles and you will see a persistence-of-vision image if it cycles fast enough.
Happy times - I hope - your projector works!
To finish up, mount the pointer permanently on an angle looking down, pointing at the mirror. Here you will need some ingenuity. The details of this will depend on what you're using for the housing and what else you got at hand. In the pictures you can see the part used in the original cardboard housing that Bjorn of Origatronica fame helped me make.
The button is most easily kept pressed with some kind of a clip. Probably you can use a clothes-peg.
Lasers work best, but If you don't have one, you can try to use the sun as a light source. Or a strong spotlight shining from reasonably far away.
