can i make a cd ir laser solderer?
iv seen a lot of projects using dvd red lasers to light matches and other cool stuff. a lot of faqs for almost all of these projects had the "can i use a cd diode" question and the universal response was "cd uses ir so u could be almost instantly blinded without knowing it" but military lasers used to safely blow up mines, pipe bombs, ect from far away (awesome!) are ir. are people saying no ir because of morons that would not only use it without goggles, but would also show their friends it lighting a match while invisibly damaging their eyes, or is there another reason why dvd readers and cd readers and writers shouldn't be used? also, is there any easy way to combine and focus multiple laser diodes? if it just takes ir blocking goggles then an ir laser soldering system would be worth it, not to mention pretty kick-ass.
