This Instructable works off the same idea we used for the Laser Pumpkin. We used assorted products at our disposal from Laserglow.com and Novalasers.com to create a festive laser display all coming from a Christmas Tree.

Step 1: Prepare Your Lasers.

For this project we used an assortment of continuous operation lasers from Laserglow.com's Brightline Series. The lasers ranged in power outputs of 25 mW to 40 mW, but you can use lowered powered units, but it won't be as awesome.

We removed the mounting brackets and prepared them with matching power supplies to be placed on the tree. If you don't have access to continuous operation lasers you can use a regular laser pointers by taping the button so it stays on. Your battery will die eventually, but you'll have a temporary solution to create your own display. Green laser pointers can be purchased from both Laserglow.com and Novalasers.com.
great job, the laser show is beautiful
this must be what the borg would put up if they were Christian.
Hi Joe,<br/>Christmas isn't a Christian holiday - it's really very pagan. <sup>_</sup><br/>
Christmas was the MASS of Christ. The Son of God. There is no Christmas without Jesus. Anyone who can read basic words would know this. One day God will prove that Jesus is the reason for the season.
Jesus wasn't even born on December 25. There was a pagan holiday on December 25 and the christians adopted that date.<br />
yeah actually he was born on the25th :P if not then when??<br>
in april
&nbsp;&nbsp;I can't believe it took 11 months for someone to respond to that comment. So thank you. I can't stand people who don't research anything and just believe what's right in front of them.
it started as a pegan holiday but was adapted to a more religious christian version by the roman catholic church during the reformation. (the day means different things depending on the religious beliefs of the person.)
You are confusing &quot;Christmas&quot; with whatever they called their pagan holiday.&nbsp; I'll readily admit that the early church appropriated some pagan dates in order to help convert people.&nbsp; But if it is called &quot;Christmas&quot; we are referring to the birth of Christ, and therefore the Christmas holiday celebrates just that.&nbsp; Commercialism, different religious (or nonreligious) traditions falling on the same date and Santa Claus notwithstanding.<br /> <br /> I hope this was timely enough for komecake.<br /> <br /> Happy New Year, btw. . .<br />
I thought that was the point of the Borg - they were Christian. "Your culture will become our culture, free thinking will be sacrificed for the good of the many, refusing to give up your culture to ours is futile, as we will overwhelm you with more advanced technology..."
Hehehe that tickles me.....<br/><br/>&quot;ONE OF US!!!&quot;<br/><br/>I'm pagan but I don't mind Christmas because it gives the Italian side of my family an excuse to make the best food on the planet and eat continuously over a 48 hour period <sup><span class="underline"><sup>. That is the meaning of Christmas right, feast? Feasting and new stuff and cutting down pine trees so they can slowly die in your living room. Ahhh, America.</sup></span></sup><br/>
2 1/2 years for me to read this, but I hate when people bring religion into my Christmas! haha
if you look at startrek cannon, the borg's assimilation is in the interests of promoting their own evolution, taking on the advantageous aspects of each species they assimilate.
why is the video down because of copywrong?
I wouldn't say that.<br><br>Whoa! I did!<br><br>No, wait...
pretty ......AAAHHH MY EYE!!!!
eye? <br />
This is for the damaged eye comments: Where sunglasses!
Old comment, yes, but sunglasses will do nothing to protect your vision from lasers. If anything, they make it worse by making your pupils dilate. Eyes+lasers+sunglasses=blind spot.<br/>Anyone who is thinking of using sunglasses as laser protection- buy some certified glasses!<br/>
i thought the tree would burst into flame
In the video, I expected it to break in out in techno music and have lasers flash all over, guess I was wrong :(. But I think you'll win the holidays contest :)
yhea it kinda gives that impression
I thought that too. Like it would be all quiet and slow, and suddenly the lasers would turn on in techno or something. lol
same lol
Yeah first thing springs to mind are young eyes staring unknowingly at a beautiful tree ***And I spy not a single WARNING label anywhere on this Instructable*** Perhaps you should just put the idea up on some kind of a website, lots of pictures and videos, and a how-to, then leave it at that? May I suggest nobody builds this at home lest some poor so and so thinks its not incredibly dangerous, which it appears to be. Incidentally is that a WHITE laser I see in that picture? How do that?
Go suck tree.
Quite random. Still, anything with lasers is cool.
Could you also add a couple lasers to one of those fiber optic trees that came out a few years ago and get a similar effect?
i love nova lasers
Well, looks kindov dangerous to me. If someone looking at it took a laser in the eye....
You used &quot;a selection&quot; of lasers that <em>start</em> at $189.<br/><br/>Any chance of producing an 'ible that requires rather less than $1000 of your lasers?<br/><br/>Maybe a single laser plus a load of beam-splitters?<br/>
Mirrors? That was my first thought -
a project for after my first million!
OMG it looks like its a version of Transiberian Orchestra Laser show! TSO is awsome This idea is perfect for my tree wickedly foshizzle!
I think this is brilliant, but surely not very practical. You can just imagine your grandparents sitting there on Christmas day. 'ooo they're nice light *Wooaaww* where did everyone go, erm.... I hate to alarm anyone but I can't see'<br/><br/>How do you stop yourself and others getting blinded?<br/>
My kids love this. Will have to play with the idea. So, not just for grownups!!! Good post.
love the cat in the vid*hahaha great job, kinda wish pink floyd was playing in the background +1
HeWantsRevenge:<br/><br/>No way is anything PF did as awesome as music by the late great Vince Guaraldi Trio for Christmas eve music.<br/><br/>You will find this to be true when you are old enough &amp; get married (great smooching music!)<br/><br/><sup>_</sup><br/>
ok... I have a 35 foot Norwegian pine in my front yard AND I live just south of LAX. How quickly will homeland security be knocking on my door? What's the throw on these lasers. Bob (the tree) would look too cool and my neighbors are sooooo competitive.
lasers beams are the true meaning of Christmas.
WOWOWOW! Nice work nova! Geesh i wish i could afford some of those lasers you have! Great job!
nice, hope a laser tracking missile doesn't follow it :)
lmfao! hey didn't think of that. we can't point lasers at the sky where i live so this is a useless idea. we'd have to keep it inside and well that's not as fun.
neat but we couldn't have this outside.. we are near airports and having any laser outside pointing anywhere specifially at the sky is a call for a knock at the door by the feds. :(
While looking cool, this is very dangerous to your eyes without proper protection!! Very disappointed that a company would peddle there high price items in this way.
Proper eye protection was worn during the setup, and with the beam-splitting diffection gratings in place each laser beam was verified to be less than 4mW total power. It looks a lot more powerful than it is because we used lots of hazer and long exposure photography. No one was at risk during this instructable.
This is really cool. too bad I don't have the money to purchase this many lasers.
this is cool. i can imagine it: "wanna go to a laser light show?" "sure!" when you pull up to your house your buddy goes: "i thought we were going to a laser light show?" with a grin you reply: "We are." then you crank up that christmas tree and have the whole block down there... AWESOME inctructable! why not make the lasers move to some music? THAT would be cool.
