DIY Green Laser Projector in 20 Minutes!!!!!!

[curryhouse]

Aw I thought this was actually 20min...

[whatisayworks]

20 minutes of your time and 6 minutes of ours :p lol

[zacktman]

you just wasted my gosh damn time

[llOneLifeOneChancell]

he sounds like the bear off of the cleveland show

[shawsbirdhouses]

y do you want this

[brandonmcgee17]

you should get some fog! then youll really have a neat effect

[hrag500]

r u armenian?

[dragonlasers]

The person in this video is Japanese American from memory.

[hrag500]

Oh, I KNEW IT!!!!! eather Armenian or Japanese

[caesarvegastube]

add a potemcimeter or regu... for motor and it's much beter to control the revolucions ! lol

[samsomiller]

are you the CEO at DL ? or just a worker? thanks..

[dragonlasers]

A worker :(

[samsomiller]

do you get lasers for cheap? wheres the factory?

[andy232005]

nice laser shame about the pipes motor and glass the laser is better on its own lol

[RomuloXK]

great idea...

(y)

5 stars :D

[240LHD]

The dancing part was funny.

[spartan5397]

why are your lasers soo expensive and do you make them yourself?

[dragonlasers]

High power lasers use expensive diodes need to be built to handle high temperatures which is also expensive.

Dragonlasers both manufactures and sells lasers.

[RukiVverh12]

Can you buy these laser in any stores? Or you have to basically order them?

Cause in stores you can just buy those small cheap red ones.... with like not even 1mW's of power.

Answer back.

[dragonlasers]

Basically you can only order good lasers online from websites like Dragonlasers

[PWMARTENS]

too bad that those lasers cost 300 dollars to 13500 dollars :(

[dragonlasers]

The portable lasers at Dragonlasers range in price from $99.99 to $1500

[Zlyzer]

And yet you advertise them as play-things..

[flavors23]

very bad for ur eyes. ur retinas can rot afta long exposure n stick 2 ur corneas. very dangerous

[Zlyzer]

Exactly. Very professional coming from Dragonlasers.

[MrOwnageJeff]

how much mW was that laser?

[dragonlasers]

That laser is a 250mW Spartan GW model.

[slasheitor]

how i know how powerfull a laser is?does the color matters?

[dragonlasers]

Laser power is measured in mW (milliwatts) and every one selling lasers will advertise how many mW a laser has.

Color and power are not related. For example you can have weak green lasers and powerful blue lasers.

[slasheitor]

thanks,but, i meaan, why a yelow 5omw laser coasts more than a more powerfull green laser?

[dragonlasers]

the process to make the beam is different and less efficient so orange lasers use more expensive components.

This makes them much more expensive.

[dragonlasers95]

You can get refractive glass from Dragon lasers

[kallaballi]

cool

[deathmaker159]

hahhhhhh!!!

[magic101magic]

where do i get refractive glass

[Ballpythondude420]

China? wow no thanks

[dragonlasers]

Do you realize the % of the things you use in your daily life that are made in China?

Even American brand name products such as the Ipod are made in China.

[Ballpythondude420]

So? The way for me to support our failing economy is to buy a 350 dollar laser from china? I'll find a company that manufactures in the united states. I'm not saying your products aren't good because of where they are made i'd just be more comfortable buying from a American company.

[dragonlasers]

Fair enough.

[motleycrueguy]

dumbass

[Ballpythondude420]

how am i a dumbass?

[haydz45]

lol laser's above 5mw are banned in the us! hahaha so you wont find an American company selling lasers!

[Ballpythondude420]

I might be able to find a canadian or british company though!

[dragonlasers]

You can find Dragonlasers, a Chinese company :)

[djsareawesome]

Do you live in the U.S.?

[dragonlasers]

Dragonlasers is in China

[liken64]

nice video

[ohhhwell]

I was just curious. o.o

[WestCoastRich]

Hey, like, take off you hoser!

[ohhhwell]

What happens if you point a Hulk Ultra at a pregnant womans belly?

[dragonlasers]

Comments like this are either poor humor or very irresponsible.

[ohhhwell]

Poor humor. ^_^

[paymybillz]

can u tell me what a viper 125mW green laser can do or make a vid what it can do thx.

[dragonlasers]

pm sent

[metallicadrummerboy]

LOLZ THE BABY WOULD GO BLIND! HAHAHAHA

[niceboar]

Wow you gotta be a fucking idiot to use that high powered laser indoors without goggles. Enjoy your retina scarring.

[ukAdamR]

There is no damage done unless the beam is pointing in your eyes.

[niceboar]

Yeah, there is. Look it up. Reflections off walls have caused eye damage at that power. But if you don't believe me go ahead and not use goggles at that power. Those little dots probably won't do it but just having the full beam on a white wall at that distance will most certainly.

[dragonlasers]

If it was a direct beam, you are right.

The transmitted/reflected beams from the diffraction grating have a MUCH lower power level that by itself is very unlikely to cause harm. The laser beams are also moving so there is basically no danger from this projector.

[MOZZWIGAN]

its ok but i dont think the image is that good for all the work u bin through

[dragonlasers]

You'd only need around 5 minutes more work to add an extra motor and diffraction gratings. That would make the projection MUCH better.

[highvoltspam]

i'm sorry, not too impressive.. a simple 3 motor lissajous produces nicer effects. adding a 4th motor (a coolerfan) that 'breaks' the beam, and you get even nicer effects.

btw, standing in the laserlight from a +50mw laserpointer without goggles is like looking to the sun with a telescope.. very dangerous for your eyesight. Even with a diffraction grating. Diffraction gratings have a zero order beam in the middle with still 85% of all it's power.

[dragonlasers]

Good points.

I don't have the exact figures on the power distribution but I think the quality of this grating is high enough to give a more even dispersion.
