Wow, thanks for giving me the idea of cd-rom motors! A quick Google showed tons of sites with information on modifying and using them.
I'll be sure to check out that RC groups site.
For my purposes I can probably even just glue the mirrors directly on to the rotor can.
I only found one motor on any of those sites that's brushless, and there aren't many specs that they show for it.
Maybe I should just cannibalize a few computer fans. It would certainly be easier than trying to hunt down the motor separately.
Some of those sites are pretty cool though, thanks...
Hopefully this is the appropriate forum for this sort of question, but I was wondering if any of you might know where I could buy small brushless DC motors online.
I've been Googling around for a while, but most of the ones that I found are too large and expensive for what I need, as they're...
You can get arc shaped magnets with the magnetic orientation you're looking for at rare-earth-magnets.com. I hope it's what you need. :) I would have posted a direct link, but I don't have 15 posts yet.
Thought you guys might find this article interesting and that maybe it would spark some conversation.
What are your thoughts on this? I think it's pretty incredible, but there has to be something that limits the process so that he can't take power away from the motor completely.

Here is a 20.5" x 36" fresnel I just found that you can buy for 80 bucks plus shipping. http://www.alltronics.com/cgi-bin/item/24L021/32/20%2E5%22%2DX%2D36%22%2DGiant%2DFresnel%2DLens
Some of them are a bit out of your price range, but here are some more to choose from if you want...
Assuming the lens could survive the already concentrated energy, I don't see why not.
For the budget thing, how can we keep a limited budget in mind if we have no idea what that budget is? Are we talking tens, hundreds, or thousands of dollars here?
*tsk tsk* They're called welding goggles my friend...:rolleyes: The biggest lens I have is a 8.5"x11" fresnel page magnifier.:frown: Douglas, your question might be easier to answer if we had a general ballpark on your budget.
