Well... on that: Why does it seem so very difficult for manufacturers to get this correct even remotely? Most of the cheaper (say <$100) commercially produced pointers have such bad drivers that the current varies wildly with battery voltage.Ummmm, How about buying a laser with a real constant current driver, battery voltage falling off should NOT greatly change the current in a modern laser,
It would be interesting if someone were to disconnect the diode from the driver and see what kind of current is possible and then look up the specs for the diode. It would be cool if we could have a suggested current for the cheapo greens that one could set using a test load so that its not just blind pot modding. Thats really the problem with pot modding, as you suggested, that it is just a guessing game.^^^ diodes are diodes. they don't come with a driver. any hobbyist that makes their own lasers "pot" mods the driver to set the current to the laser diode. But this is done safely because we know the max, and long life settings for all the bare diodes on the hobby market are.
Now with complete lasers already sold there hasnt been the research done. So that is why it is not a good idea to pot mod your premade laser. Unless you don't care about ruining it. Then by all means, crank that bitch up!!! I do. LoL.
