I've decided to start saving up money to build my own spirograph. I'll use 532nm, 405nm and 660nm lasers for this project. That should give me a nice variety of colors without spending big bucks on a 473nm laser. I'm looking at 50 to 60mW of green. I know I'll need around 180mW of 660nm but i'm not sure about 405nm. i know it will be a PITA to align the beams but that is part of the fun.
I am going to compile the list of needed parts here. Feel free to let me know if I am forgeting something.
project box of some sort
couple motors - probably use PC fans
couple surface mirrors
motor controls - obtainable at radio shack
beam dimmers - obtainable at radio shack
power source - probably 12v
lasers
a way of combining beams
I am looking at this for a green module. I'll probably get the heatsink from them also. http://store.nexternal.com/shared/StoreFront/product_detail.asp?RowID=165&CS=jmm6360&All=
I'm willing to pay somebody to put a high powered DVD diode in a housing and custom heatsink with 4 holes drilled for mounting. It just has to be powerful enough to match the brightness of a 60mW green.
I know it is hard to get enough 405nm to match the brightness of 60mW green right now. This is the reason I am going to take the time building this. The 405nm portion will probably be the last thing I wait on to finish this project.
I am open for options on the box this will go and and powering it. It would be nice to have the power supply built inside the box or have a 12v high amp output phone charger or something similar. The reason I say 12v is because I might use computer fan motors to put the mirrors on. The ones I get will probably be running around 6000 to 7000 rpm @ 12v. I might even mount a 80mm fan in the box for cooling. I am thinking about mounting the lasers and motors on a seperate board inside the box. I'll try to find some spring mounts to help cushion the laser/motor board.
I am open to help and suggestions. I just want the final product to look as nice as possible.
