Laser Light shows

Post by Zipper » Mon Sep 13, 2010 10:48 pm

I am interested in doing a laser light show at my camp for 2011. I plan to use commercially available lasers and follow the recomended safety procedures for same.

Are there any clearances I need from Burning Man to use these devices?

Much thanks,

Zipper

You'll need to apply for a Laser Variance (google it) if you are using above 5mW (cheap laser pen is 5mW).
Rather than buy lasers off the shelf (unless you are prepared to spend a lot) have a think about making your own effects - its not that difficult and by doing this you can also make them more playa proof!
Dont forget compressed air to keep your mirrors clean!

Seriously, Zipper, I haven't been able to find any word on the BM site about "clearances". You're mostly on your own. ;)

Apply burner principles, see how radically self-reliant you can be. :)

What class of laser are you using? Are they aimed at people (audience scanning), or above head height? I can't believe I am turning into an LSO. :)

From another post a year back as well:


Any laser that exceeds 5mW (regardless of color) will require permits from the FDA's Center for Devices and Radiological Health (CDRH). If it will be operated outdoors the FAA gets involved. There are also state regulations. I don't know about Nevada but in Arizona the Arizona Radiation Regulatory Agency (ARRA) issues permits. Fines for operating a laser light show without permits are in the thousands.

Here are a couple links:
http://www.fda.gov/cdrh/ocer/guidance/1639.html
http://www.faa.gov/about/office_org/hea ... /service_u nits/systemops/aaim/organizations/airspace_rules/laser/

In addition to being illegal, operating a laser with more than 5mW of power in an unsafe manner really is dangerous. These lasers should never be pointed at a person and can cause eye damage. There is a black spot in the vision of my right eye that was caused by a laser pointed into the crowd of a nightclub about a year and a half ago.

I have informed the rangers that many of the lasers operated at burning man are potentially unsafe. They never responded to my email and I still saw many "illegal" lasers last year.

If you want a laser to play with I'd recommend a green 4.9mW laser pointer. The human eye is most sensitive to green, so a green laser actually appears brighter than any other color (at the same power level).

I know someone manufactures filters that you can put over the end of a laser pointer to diffract the beam into an image like a star, heart, smiley face, etc.

If you want a laser that will do some crazy tricks for you then a fixture like the American DJ Krypto Sync might suit you. There are also less expensive fixtures that are comparable to the Krypto Sync but use red laser diodes.

http://americandj.com/ProductDetails.as ... egory=Lase rs&txtSearch=laser%20widow

here's a much cheaper portable one:
http://www.thinkgeek.com/geektoys/science/97ab/

There are also fixtures that use multiple 4.9mW laser beams to create a much larger effect without needing permits. Here's a link to the American DJ Image 8 DMX:

$30 on Amazon, but dim as hell unless you're getting high power ones that you need permits for.

But yeah. They make me smile, too. :)

I like the long haul optical network lasers in the 1350 nm wavelength.

Someone invariably turns one on and then stares into the emitter looking for light, until someone says: "what's that smell"?!

I'm actually starting an eplaya petition to ban all feathers, cigarettes, glow sticks and dangerous things at BM next year.

Zipper - check these out:


I own one and they are really fucking cool...
Work great for a small space - say under 400 Sq Ft.
You could always get 2-4.
The purple hazy BG they project is killer. Very trippy.
I had one running inside my Hexayurt last year and it was really fun.

As if it weren't bad enough that we have spammers like lightlase, but the fact that they perform forum post necromancy is just insult to injury.

oh man, that's no fun.
get above about 50 watts and they work real well for cutting off body parts. Had a 60 watt CO2 laser at work. Co worker "discovered" they work exceptionally well at trimming finger nails and tip of finger. at least it cauterized the wound...

My friend Jim just told me on Facebook at he got his three 1.5 watt lasers today for the 1 Mile Clock Project for Burning Man this year!

Every laser jock in the world worth his salt has a scar on his hand. Or a spot in the vision that won't go away. What fun!

I thought that 'nm' rating was the wavelength of light or color?
the 'mw' or 'W' rating was the out put power?

Yeah, but if they're in the UV spectrum, you're still going to have trouble seeing them, unless you got some fluorescent paint. :)
