Alright, guys, I'm trying to make a kick ass laser pointer as seen here in this video:
I have everything that was talked about in the video except for the housing and flashlight (which I don't really need at the time.
I got the laser diode out of a 16x DVD burner like the video said to do.
I also have the 2 "AA" batteries to provide the voltage needed.
Now, how come this isn't working? I have followed the videos instructions. I have checked the battery assembly with a multimeter to make sure it is working correctly.
