I doubt that there was an actual injury. I think the reporter half-assed the news piece and interpreted "blinded" as injured. If you take into account atmospheric attenuation over 5000+ feet and divergence, you'd need something extremely powerful with very expensive optics to get anywhere close...

You just have to avoid exceeding the power rating. For five lasers, you certainly would want to double check, but if you are running them at low levels, I think there's a decent chance that it would work, especially if you used two cells. The trouble with a build like this is that increasing...

You strapped 10 5mw green modules to a pair of gloves... I can see ~75$ for the lasers, 5$ for the battery, another 30$ for the gloves and material. You could buy some of those cheap 7$ ebay pens, pot mod them down to safe levels, solder the switch close, and chop off the end just below the...

Are you planning on selling any bare heatsink kits at any point?

Any word on this kit?

Thanks! That's very helpful!

I saw that thread and a few others, but they focus pretty heavily on the electronic design rather than the design specs. They don't really answer my specific questions. I have no problem going at this from the electronics end of things, but I'm just having trouble getting info on what I need...

Hello all! I'm looking to do a driver design with a friend, just to help teach ourselves about power electronics. I've done a bunch of reading on the forum, but I have a couple of questions. I'm sorry if they are common knowledge, or if I missed a thread with that info in it already. (I tried I...

That's false. Any good glasses should easily protect from a direct hit in their blocking region. If you use OD1 glasses, then, yeah, maybe.

Remember that the inverse square law does not apply to lasers. That's the whole point. :) Laser attenuation is more or less linear for all distances where beam divergence is small.

Thanks on both counts!

I had to finally register to ask this: Will we be able to purchase these lasers directly from Jetlasers as soon as they are available? I am sold.
