except AC mains is sinusoidal while the laser pulse graph would have a rectangular pattern from maximum to 0.But I'm sure you could make a sinusoidal pulse laser :)

Keep telling yourself that and you'll end up like this guy http://www.theonion.com/content/video/courageous_man_refuses_to_believe :D Seriously, don't try to remove your girlfriends moustache with a laser, you can give her some nasty burns and scars.

Awesome! but , maybe I'm not remembering correctly, but didn't someone already had a laser warning tattoo? I remember there was a thread....

They were made from a bar with a hexagonal section and were damn hard to cut off too....I messed up two saw blades.

Well changing the Nd to CTH makes all the difference since that's the actual active stuff that does all the lasering(that's why Nd:YVO4 does the same as thing as Nd:YAG).The YAG.YVO4 is only an optical medium to hold it in.Btw, can't you pump Nd:YAG with 808nm LEDs?You'd have to get them pretty...

Well that's certainly an interesting post. But this looks like it would rather help you avoiding such situations.Besides you'll pretty much have to go all the way to know what you should do if you were the victim already caught right?I know the point is not to be caught in that situation, but...

Thanks everyone! :D That odd look was what I was looking for.A bigger aperture for a smaller beam just doesn't look right to me , even though the difference in diameter is huge here, lol. Besides , I wanted to keep the dust that gets inside to a minimum :D Anyway, my machining skills are...

Well there are laser removal devices but they are not to be operated by just anyone. I think they use a low powered red laser for aiming and a pulsed YAG that does the burning.Removal has to be done one hair at a time. You could probably build it but it won't be that easy.And if you do build...

Are you sure lasers are being used this way? Cause the way I imagine it, smoke that isn't already visible won't show a beam from a laser in daylight unless the laser is pretty powerful, considerably more than 30mW of green I would think. :/

spammeriffic :D

Well I saw the video if you mean the Future Weapons entry.But that's plain BS.Wickedlasers is selling a huge heap of BS and this is just part of it.Their strong point is advertisement and flashy looks.And that video is just advertisement. I wouldn't be at all surprised if we found out that they...

I made a RCR123 barrel for my DX30 because it was a POS and getting very unstable at low voltages from 2xAAA NiMHs.So I carefully dissasembled it with the non-destructive hack and slash on the lathe method to be put in the new host lol. The body is aluminum and the caps and button are brass.The...

They don't work because you're supposed to put the video ID between them (giBNVcgiPZc in your case) not the whole URL. Good luck with the scanner, looking good so far :)

Seriously, I can't understand why you would give such advice? It's not "designed" to temporarily blind, it's just a 100mW focusable green dpss laser just like anyother 100mW focusable green dpss laser appart from the fact that maybe it's somewhat shockproof so you can mount it on your gun...

Most likely it's not possible, and if it were I don't see why it would be cheaper.And yes those aren't meant to be dissasembled.I tried opening one up with the "drilled wood and vicegrip" method that just messed up the black paint and finally succeded with the "butcher it on the lathe" method :)

Wow awesome!! I thought they were all photoshoped to death, I can't believe they're real! How is the last one obtained?

This is going to be really amazing if you actually go around and build it!! Ambitious indeed.Also looks a little expensive and time consuming. Can you post some pictures of the parts you have? I'm especially interested in the 5 button lock, I'm not sure I've seen any of those.And are you going...

I know one of the hardest metals is chromium, harder than titanium.But anyway, metals are almost always best used in alloys.You can probably get harder stuff with some quenched alloys or tungsten carbide.But on 700+ MPa on the Brinell scale, titanium probably wouldn't be too easy to machine. :/...

You'd better go with aluminum like everyone else.Copper is pretty nasty to machine too, aluminum , on the other hand , is pretty smooth.And the difference in heatsinking abilities is negligeable. The aixiz nut thread can be done on the lathe if you don't have the right tap.I just finished making...

It's mAh not mA/h actually, not quite the same thing :P But anyway. what kind of battery life do you get? And can the big battery really handle such a huge current draw !? :O
