Got my blue ray built a few days ago which is running at 100mA. Something odd has happened to it though... It was working fine for the first 2 days with a very bright dot, easily visible beam in a dark room and stings the skin a bit.
I got home from work one day and put the batteries in and its gone somewhat dim... Not to the point where its no visible, it must have gone to about the brightness of a 10 - 15mW 635nm red. I have tried different batteries, rechargeable and everything and it doesn't seam to want to go back to the power it was. I even tested the batteries and they are putting out 4.5V which is the same as what they were doing before when it was working fine.
Not only has it gone dim but it now has a strange halo, well its actually a rectangle. It never used to be like that, it used to have a normal dot instead of the rectangle. See picture.
Any ideas whats gone wrong? I didn't leave any batteries in it or anything, I just put it down for the night and next time I used it this happened.
