> http://laserpointerforums.com/=20 There are some people on forums like that who know their stuff but I was quite disappointed at the number who (a) don't know how to drive a laser diode properly and (b) wave them around like toys NZ is introducing legislation in a few months to limit the more powerful lasers to those who can justify the importation, partly because of the d***s who shine them at planes But AFAIK no plane has ever been brought down or even compromised by a laser strike on flight crew. Yes, it's really really annoying but not 'dangerous'. You could cause more havoc on a busy motorway or intersection with a $2 keyring laser pointer Joe --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
