I pulled out the trusty blue ray of death last night after a few weeks of neglect. (Didn't have the heart after a forum member had stolen from me) As a whizzed the mighty blue bar of fire across the crisp blackend sky, I heard someone across the street, wondering around in one of the yards yell, My God - What is it? At that instant the laser went from a normal bright beam to instantly dead! I mean just nothing. Now it was my turn to yell, My God!
My fairly new first build / First ever laser of a magnificent 2,800mw just blew up! It had only been used about a total of 15 minutes of on time, and never any longer than about 45 Sec. I pulled it apart and checked switch continuity. All good. Check the diode window. All good. Put the fluke on the batts, and first batt was a lowish 3.2V - OK. Second batt was 0 volts.
Huh?
0 volts??
0 volts!
OOOOOH - Then it hit me. Voltage protected batts! I threw them on the charger, and the mighty blue lives again!
