Re: FS: >90mW Blu-Rays, two models: OPEN
Oh, there is one thing you all should know about these lasers. They have a tiny driver (13x9mm), that boosts the voltage and constantly adjusts it, to achieve constant current. The driver can give the diode the exact same power down to 2.4V.
Due to the way it works, you would not notice any decrease in power (not even on a meter), until the battery is completelly empty. And since you will be using protected batteries (or at least you should be), the battery will simply shut down at 2.75V.
The laser suddenly shuts down, and the first few times it happened, i got very scared, even tho i should know this..
It'll scare you too, but if the laser suddenly shuts down, just press the switch, to to turn it OFF, and put another battery in. The best thing to do is charge one battery, and use the other.
The switch should be OFF when changing the battery, or your laser will blink ON and OFF, while you're putting the tailcap on. Diodes usually don't like this too much, so you might want to avoid it. There is of course a cap directly on the diode, to soften the blow at power ON/OFF, but it's still better to be safe than sorry.
Sometimes, when i show someone a laser of mine, they first point it around, and then they start blinking it. At that point, i usually want to hit them. ;D
