Hey, I am fairly new to lasers and so I only have my first build, a "100mw" from Deal extreme. I would guess 35-50 mW because it still pops balloons. I dont have glasses and so that's my first question, where can I get cheap safety glasses that protect from blue to green. I mean CHEAP! Also I have made an lm317 driver set to 120 mah. This will drive my laser I'm building, a PHR803t in an aixis. Now my biggest question is how many volts do I hook it up to? Can I use a 9volt? Or what? Thanks
