I ordered 532nm 50mw Sizeadjustable Green Laser Torch [RF532-50mw-B03] - $31.99 : Rayfoss Lasers!, Rayfoss your trusable onlinestore a while back and it worked fine for quite a while. Then one day it just stopped working; sadly it was after the warranty had expired. I simply gave up on it. Yet today I decided to look into them again, and decided I wanted to figure out how to fix this thing. Does anyone know where I should start? How I figure out what's wrong? How to open it? What I need to fix it? Etc. Thanks guys, I'm hoping this will save me some money and will be a fun thing to do.
