Oh, I certainly have looked at some of the builds like jayrobs!
Again, there is no scale, so it is hard to tell, but this design is for a AAA battery... so I don't expect more than 400ma of output. Paul, the module it the top tube, and the whole unit acts as part of the heat sink
The user would only have to press his diode into the copper diode housing ( the one that is 11.95 x 12mm and contains the 9mm lens), solder the driver to the diode and just screw it in
I would love to make 2amp builds, but I like pocket size housings and I have yet to find a battery that can output that much current which is small. I do have a 2400mah AA... but because of the battery chemistry it outputs less than a lithium ion.
I like the simple small builds, 500mw is still a lot of power
but if nobody on this forum cares for that then I can make some 2w+ lasers
