The easyest one is to get a small vibe motor from an old cell phone and glue it to the back of a small mirror. Add a trim pot to the power going in, the different voltages produce different patterns. My avatar on the left was done in this fashion.
Now I may be wrong here but I have reasoned that if you spread a 10mw beam, with a line generator, over 10 feet that equals 1mw per foot....If you rotate a mirror to reflect the beam, every point gets the full 10mw repeatedly....... :-/
i dont have any of that stuff, i got a cd player ( im not allowed to break)
I can find some plastic mirror at my local craft store
And i have a few cd's that i dont need
I also got an old cell phone, i dont use
Could you tell me if i can make anything and instructions?
Yes, simple as that a mirror on a computer fan...the hard part is getting one line, it took ages to set up, most times I ended up with 2 lines (one from the front and one from the back of the mirror).
@ rip92 If your phone has a vibro motor, take off the eccentric weight, taking care not to bend the shaft, put on a mirror as described in the hand held projector thread I linked to earlier. That will give you a tunnel effect.
