So a 1w gatling style chinese thing is getting delivered to me today, and I'm stoked, but I can't stop daydreaming about a 5-7w laser. I'd like to slap together a sweet build, but have a few questions, and definitely need to find a proper host.
Here's what I want.
Nubm44/nubm08(???)
G8 lens
Host for 2x 26650s
Beam expander
Driver.... (Super x drive from dtr work for this setup?)
And a module of unknown size.
So on to the questions:
1. I'm aware the m44 has garbage divergence, so is the m08 really all that much better?
2. The m08 is the diode used for 5w lasers right? Maybe over-driven a bit?
3. I don't know what size the host/module should be?
4. I think the super x drive is the correct driver for this as 2x 26650s = 7.4v in series. Not sure how to properly adjust it though. Something about a test load and I guess I turn a pot with a DMM hooked up somehow? I've done research but I still don't know exactly what to expect.
5. Optics?! It looks like a g8 lens can screw right into a module, but how do you mount a focus lens and a beam expander? Is there a 2 in 1 BE + focus lens? Or is there a host that somehow accepts both?
6. Battery connections. So the host itself is the positive and I still need a spring for the negative battery terminal to driver?
7. Theres some other spring involved inside the module too? For the lens or something? Please explain.
8. Money. How much should I expect to pay for all this crap? Hopefully less than the $350 or whatever it is that sanwu wants for a 7w striker.
Thanks for any answers. I've done a lot of searching and reading in this forum but It's hard to understand what exactly I'm supposed to do without the laser parts in front of me for reference. I was thinking to buy internals from dtr but still need a host at least. I don't want to buy a bunch of mis-matching parts and have multiple shipments for things I forgot. Your expert guidance is appreciated. Thanks.
