laser spirograph tutorial

[tony70516]

hey guys this is my spirograph for my 100 mW green. (which hasnt arrived yet but ill post updates when it does!)
its very simple, gets the job done, i havent added potentiometers yet but i will.
what you need.
2  12V brushless cooling fans (radioshack)
2  4XAA battery holders (radioshack)
1 switch (radioshack)
foamboard (or any other houseing and base material, its your call. i like foamboard the best!)
hot glue
solder

the whole project comes out a little over 25 bucks.
the thing that kills you are the motors they're 12 bucks a piece.
i know i shouldve taken pics as i built it but i didnt realize i tried to paint them as best as i could.
please post comments and replies. tell me what you think!
I tested this with a crappy led light and it works beautifully i just need my laser to post some really nice pics.
thanks

ps. i apologize for my aweful setup of all the steps. hope you understand.
thanks again
