Hello, this is my first real post, so hello. I have mounted a metal octagon shaped piece from a bicycle headstock onto a DVD drive motor. When I shoot my laser at it while its spinning, I still just get one single dot instead of a line. Can anyone tell me what I need to do differently? Could it be my $3 laser pointer from petsmart isn't strong enough to produce anything but a single point? If anyone is actually interested I can probably get a picture of it. Thank you!
