I had a negative ion generator in my bedroom, and anything plastic (mains plugs and sockets for > example) within a few feet of it was covered in a fine dust within a week. And while the mirror wouldn't be more positive, if I'm correct the laser sure will be as all these laser modules have a positive case... Some of that dust would probably get to obstruct the lens in the laser soon enough. -- pete@petertodd.ca http://www.petertodd.ca -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
