Just wanted to introduce myself. I've been a laser hobbyist on and off for about 10 years. I just recently jumped back in. This site huge and there is a lot of knowledge here! I have been using this site extensively. I found it much more productive searching with google than the "search button". It usually leads right here anyway (with good results). I usually don't post questions. Everything's already been posted here anyway, right? But... I got a lot of new toys coming, and I'll be tinkering with drivers and diodes and optics. If I absolutely am banging my head against wall, please allow me to post here. Thanks!
