I'm scared to own one of these due to accidentally destroying someones eyesight, or my own.
[QUOTE=Extroll;24124373]I would love to take this to school and light things of fire.[/QUOTE]
wow
The video hurt my eyes at the beginning
Im tempted to build this.
Holy fuck I read the title as "How to build a [B]1mW[/B] laser" :ohdear:
[QUOTE=superdinoman;24128559]Im tempted to build this.[/QUOTE]
For all the parts + 4 special batteries and charger (you wont actually need all 4 batteries)
~$165
VS
$299 for the equivalent manufactured 1W
Considering new laws, US Customs, and benefits in just replacing specific parts if broken, it's a good deal. If you know how to put it together.
Video saved to my computer just incase.
Definitely going to make one of these eventually.

You don't live in Australia do you? Forget what your not allowed to have, but all the good ones are illegal here.
[QUOTE=SGTNAPALM;24100070]The fact that any idiot can own this and just wave it around without restriction scares me deeply.[/QUOTE]

they are. lasers like this are banned in the us.
the maximum you can have in the us is really low.

Only <5mW can be imported, laws govern the class & licenses, offensives (like pointing a laser at an aircraft).
It's not classified as a weapon, it is no more danger to anyone than a kitchen knife
Would the individual parts get past Australian customs?

No, but if you want to be sure you'd have to check with them.
[QUOTE=sa2fan;24099924]Pretty awesome. I have a 50mW greenie. [/QUOTE]
What the christ, 50mW seems pretty scary.
[editline]asdf[/editline]
Nevermind, got mW and MW's mixed up. Jesus christ, that'd be scary as balls.
[QUOTE=sa2fan;24101724]People often exaggerate on how many things in can burn. Like what you said, walls. I won't, it's not 100W or some military laser. 1W is about the limit of someone having a laser.[/QUOTE]
Even 100W can't burn through walls effectively. I once burned through a razor-blade with a [b]focussed[/b] 10W and a a 55W laser. It works when the waist is small enough (200-50 µm). But as big as the laser-beams are in that video (2-10 mm), it's not possible.
For burning through a wall I'd suggest using an industrial 100 kW CO2 laser (focussed of course).
You guys be sure to start with a simple build as he mentioned or you'll poke your eye out.

Define "low". Even 30 mW can badly damage your eye.

Wow, where did you get those?
[QUOTE=aVoN;24136788]Define "low". Even 30 mW can badly damage your eye.[/QUOTE]
well then don't buy shitty unfiltered lasers
[QUOTE=sa2fan;24136819]Wow, where did you get those?[/QUOTE]
he probably works somewhere that deals exclusively with industrial cutting or something
don't bother, even if you could get your hands on an industrial cutting laser, it's not going to saw through houses from a mile away. plus you'd need nothing short of several welders masks and a HAZMAT suit.
I know some people have succeeded in over-volting laser diodes in the past to get more power out of them, and water-cooling them on top of that. Wonder if that'd work with one of these...

Pot mode?
The price of this project would be completely ridiculous
[QUOTE=Turnips;24105694]I can see this being a new way of mugging people, run up a to a guy and shine this in his eyes so he's blinded, then steal his shit.[/QUOTE]
Permanently blinding someone is totally worth $40!

verses buying the manufactured equivalent, it's better

True the USA laws are ridiculous.
In Australia the restrictions only apply to hand held laser pointers

An idiot wouldn't be able to assemble this.
People wonder why I freak out when they beam me with a laser, I have no idea if they are fucking around with one of these high powered ones.
