Looks very nice. :)

I think laws are a little different here in Canada.. Hehe.

Deer hunting! Lol jk. Well, me and my GF have been doing some weed wacking with it! I was also thinking of making rubies using the laser. could be some fantastic click bait on Youtube!

To be honest I actually find some military 'rules' to be a little funny and ironic. Lasers that can blind, or bio/chemical weapons are not more 'cruel' than napalm or phosphor artillery, or many other weapons in use. I honestly think part of the reason for these rules is actually based on...

Yeah, it does make me wonder how far different military/weapon companies have gone with it. I can see why they would keep it a secret, as that type of weapon is in sketchy territory as you said. I mean, there was that bold claim from China that they were working on a near lethal laser rifle...

I am interested to know how far people/companies have taken this. It's hard to find much out there for portable hand held 'laser weapons'. I honestly think it's theoretically possible to make a 1kw laser rifle in current times, as I have fairly small bike batteries that can output 3-4kw bursts...

Thanks for the links. Yeah with laser glasses I was more referring to the bright white light when melting metal, doesn't get filtered very well by most laser glasses, if I do more welding, I might buy welding goggles to pair with laser glasses. Hahah, yeah those battery holders I bought were...

That is the plan. You might notice there is a rail on top of the gun. That's actually how the 'hood' sits over the laser diode. The slide is meant for any ad on's I decide to make. And that includes a beam expander. Today I was attempting welding with the gun. I bought some welding rods...

I was wondering if anyone has experienced eye injuries, or know someone that sustained serious eye injuries from lasing. I haven't seen other threads on actual accounts. I want to know stories, on simple/unlucky mistakes that led to eye or burn injury. Might be very insightful to some. It's...

Wow.. The second I posted this, the site went down for like 4 hours..

Hey everyone, as promised, here are some pictures of my WIP laser pistol with the Nubm31 designed from scratch with 3d printed parts. 8 Panasonic 18650s are outputting 260-280 watts, which after voltage step up ends up being 83v 3.2-3.3 amps. The gun is pretty ugly right now as some things...

I'll be posting pics of my laser pistol setup in the next day or 2 everyone!

I'm sticking it on the back of the gun above the handle grip. Yes, it's gonna look a little funny, but I don't care. :)

I would question the legality of selling such high power hand held lasers though. Perhaps sell it as a "portable laser welder", even though welding would probably be pretty difficult with this device, as it's power level isn't qualified for that.

no driver, I just plugged the diode directly into a wall outlet. :) Joking. I bought the array from techhood on ebay, and the driver is a cheap $20 voltage step up/regulator (running 32v-80v) rated for 600 watts from amazon(Seems good so far). Currently running just 8 Panasonic 18650s in...

I am having trouble understanding why everyone is using massive blocks of metal for cooling for the nubm31. I am using this $20 CPU cooler and it works amazing. Thing is barely luke warm at 3.4 amps. Cooling is about surface area and air movement. I mean, we have many years of tech behind...

I do get that, I was going to put 2 - 12v batteries in series. The problem is not with the output though, the damn thing simply cannot even receive a high amp input without exploding.

It's the nubm31 95 watt. This is what I am using for a driver, it's supposed to handle 600 watts.. https://www.amazon.ca/gp/product/B00C498MGY/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 Using my power supply I can only output 28v 5 amps which I am stepping up to 75+volts.(Which this...

Yes, and it 'regulates current'. Only seems to regulate output, and hooking up a high current source cause a massive surge to the unit. Any easy way to hack this?

First off, forgive my ignorance, I am a newb. I've been scratching my head over an issue I am having. How do you limit very high current from say a 12v lead acid battery to protect a driver? I hooked up a driver that was rated for 36v and is supposed to regulate current, but the driver popped...
