Was just wondering if anyone's heard of this guy. He's selling on ebay as lakotaoutlaw with an email address of xxoglala_outlawxx@yahoo.com. Got some neat looking hosts. One called thunderstick and the other blue arrow warhead.

Well, I guess I shoulda kept my mouth shut. Listing is gone.
That's what I also thought at first... as I said before, I've also talked to him on phone and he talks fast and low. The last time I had earbuds in and still couldn't understand him. After all this, my opinion of him has changed. Do tailcap spring shorts cause driver death, taking the diode with it? So far, I've been told no, it doesn't. So why is a nice guy trying to get sixty more bucks out of me for something he sold me and I didn't even get ten days out of it, by telling me something implausible happened that I supposedly caused just by putting batteries in it? Problem is,I was fixing to fall for it, until I talked to a few, more experienced guys.I just spoke with him on the phone for over an hour. He seems like a nice guy.
When I opened the host I could smell something burnt. Its some kind of Aurora X-06 with a rick trent sink, jib 1.4 amp driver, with the resistor side sinked, IC not sinked,and a solarforce tailcap using three 16340's for power.
That's why I was correct in getting him to send it back without fooling with it, then. He would have messed it up again. You know, the guy promised lifetime free labor, not parts, so legally I guess he had me there, and I'm not positive he would have made anything off the parts, unless the diode is still good. He wasn't gonna get anything else out of me just on general d***** principles, though. It would have been nice if I'd have listened to my gut the first time, then I wouldn't be in this position. But now the warning is out there, if he doesn't change his name up.This guy shouldn't be selling lasers.
Why he would use three lithium ion cells to power with a linear driver that is known to only require two (even fairly depleted) cells, is beyond me. But the fact that he would do that without heatsinking the IC? That's frosting on the cake of idiocy.
Here's what happened -
This guy built you a laser that draws 17W of power from his battery setup. A bit under 7W is dissipated by the diode in the form of optical output and heat. A bit under 2W is dissipated by the current setting resistor (which was heatsinked... great). But that leaves almost 9W of power to be dissipated by an un-heatsinked IC!
FYI, the math is: (4.1*3*1.4)-(1.25*1.4)-(4.75*1.4) = 8.82 W
Nothing broke your laser except for this guy's lack of experience. He built you a laser with a design that anyone on this forum would have known was completely foolish.
