Step 1: Make the Spinning Mirror
steps 8 & 9 here-http://www.instructables.com/id/EXB5CA21JPET9K5F7Y this
is the genius of the project.
I Used a little 3 volt radio shack motor with the cog on it, and drilled a
hole in the bottle cap. Then I pressed the cap on the cog and put a lot of
super glue gel on it.
For my needs mounting the mirror at a 45 degree angle produced a vortex that
got too big in too short of a distance, so I just glued the mirror in the
bottle cap at a couple of degrees so I could get a tube of light.
Step 2: Make the Motor Mount & Attach to the Base
I had to use the 2x3 bricks on top and bottom because when I sinched the zip ties down It spread the pieces and those bricks held the assembly straight.
