Hi I'm new to the forum and new to lasers. I'm a musician and always loved to watch lasers at concerts, now I'd like to add lasers to my own performance, i've read some threads about safety, what to begin with, diodes, housing, etc. But I'm not sure if I need that for my application. What I want to have a few laser effects, like tunel and other more I see on Pink Floyd Pulse dvd (downsized of course :yh and a fog machine to start. I've been looking at some dj laser projectors on ebay, but i'm lost. Also I can't control it since I'm playing, so it gotta have some kind of start by sound, or a on/off footswitch or maybe a computer program. Of course I'm just starting to learn about it and want to start small and have fun with it. Any help would be appreciated, thanks.
