Cosmic Color Pixel Tree

Recommended Posts

I made a tree from 12 strings of Cosmic Color Pixels. There are 24 bundles in the tree, each bundle is made from half of a CCP string.The CCP strings are inside of a transparent tube to help keep them oriented in a uniformly. There is also a sphere at the top which uses 2 Cosmic Color Pixel strings. I made a demo/test sequence to TSO's Christmas Eve Sarajevo 12/24 (Carol of the Bells). The youtube video is at:

Very nice! How many networks are you running (and type)? I had 10 CCpixels strings and was never able to get them to do exacty what I wanted.

What tubing did you use?

Very nice! I especially liked how you did the spiraling effect across the strings.

Im a newbie on here and this is my first post but Ive been a long time reader of the forums. This is the most incredible tree Ive seen yet. Thanks for sharing.

Wow, Brian, nice job... Want to provide more datails on the tree? Materials, construction techniques, etc...

Thanks.

I am using 2 networks. 6 of the tree strings are on one network, and 6 of the tree strings plus the 2 sphere strings are on another network.

The "tubing" is the stuff they use to channel groups of wires with, they are called a "wire loom." It uses 300 ft of 1" diameter clear wire loom tubing. There is also a 1/8 inch thick rope that the tubing is zip tied to. The 1/8 inch polyester rope is big enough to zip tie to, but small enough you don't see it.

The sphere at the top has 4 rows of lights, each row has 24 pixels, plus there are 2 pixels at the top and 2 at the bottom for a total of 100. The controller for them is inside of the sphere. The sphere is made of two hemisphere's actually, and there is a clear plexiglass disc that is in the middle that both spheres attach to to give it strength. The mast is attached to the center plexiglass disc also.

2 networks? Are they regular USB LOR Networks? (not the superspeed or E1.31?? Wow, I am impressed! Are you using a lot of MACROS (I do not know how the SSE works really)

If I tweak a sequence to your nework specs (and you have time) could you run it an film it? It wonlt looks nearly the same sue to the difference in setup, but I would be able to see uniformity in the big transitions.

I am having issues and working with Dan (he has been busy though) and I am holding off on purchasing more until i get these problems (http://forums.lightorama.com/index.php?/topic/20956-ccp-santa-house/)resolved.

I skimmed through the topic you reference. You have quite the project going! Not many people have done such a dense matrix of RGB lights.

I am running 2 standard networks, they are not superspeed or E1.32. I am not using any MACROS. Everything is raw channel commands. However, realize that updating video requires more bandwidth than the sequences in the the test videos. The one place that is a stress test in my videos is in "Carol of the Bells" where it bursts into white, it is turning on every pixel to white. There is a small amount of lag but not much, but perhaps that is because it is turning on every pixel to the same color and I am told the LOR protocol does that better than turning every pixel to a different color.

It was interesting to watch your different test videos. The first one where you are running 700 pixels on one network shows a lot of lag. My tree and sphere have 700 pixels on 2 networks (300 pixels on one network, 400 on another). Make sure that in the LOR Sequence Editor that you have "Short range faster" selected for the network speed in the Netwok Preferences dialog box. If you already had "Short range faster" selected in that video, it is lagging more than I would expect.

Brian,

Let me get this though my febal brain. To make a tree like yours, I need 7 controllers (Light O Rama). One controller for the ball and six controllers for the tree. Which means I need to upgrade my lic. to 24 CCR. Have I got this straight?

Thanks

Thanks Brian, I guess I will update soon. I think after I get one of these supersatar sequence loaded into my LOR sequence editor, I think I'll be able to go from there. One other question. Each contoller has two strands of 50 ea rgb's. Does that mean it acts like two controllers? One controller per strand? And do you asign each string of lights a chanel like in LOR? I've worked on two songs so far and am pretty happy with the result, but, I haven't done anything but save them in the Super Star softeware. I built mine on you samples. This is really pretty cool software.

Thanks again for you help.

Yes, each CCP or CCB controller acts like two controllers and will control two strings of 50 pixels or bulbs each.

When you configure them in "Dual Normal" mode, you only set one Unit ID, but internally it uses that Unit ID for the first string and it uses the unit ID after that for the second string. So for example, if you had 3 controllers and 6 strings, you could assign the controllers unit Ids like:

08

0A

0C

The unit Ids used for the 6 strings would be:

08

09

0A

0B

0C

0D

After watching your video of the pixel tree you did, I set up a patice tree. I only have two CB100D's nt the moment and only one is working. I attached my strings to a 1/4 nylon rope about every 2 feet and then put the wire loom over them. I attached the rope to some short bungee cords and left slack from the controller and where I attached my first zip tie on the rope. I zip tied the wire loom about every 4 feet. Seemed to work pretty well. However, I think I might change the rope to cottom, as I don't think cottom will streatch as far as the nylon rope. And I might do away with the bungee as well. I think I will also have some conduit rolled into a circle for the bottom of the tree to attach everything to.

 

Any thoughts on my idea?

 

Thanks

I think you have improved on what I did. I put the CCPs inside of the wire loom and then zip tied the wire loom to 1/8 inch nylon rope. The problem I had was that the lights slide around inside of the wire loom and in some places it was hard to get the pixels lined up right. By attaching the CCPs to the rope first you can move them up and down on the rope to get them aligned.

 

I used 1/8 inch nylon rope because I did not want the rope to be visible. You used 1/4 inch nylon rope, are you able to see it in the dark when the lights are on?

 

As for using cotton rope, realize that cotton rope stretches more than nylon rope. The advantage of cotton rope is that it is less "slippery" so the anything zip tied to cotton rope stays put better.

If you are worried about stretch, 1/16 galvanized vinyl coated aircraft cable works well, and does not visibly impact light output. And gets a good marks for not slipping.

When I import my visual pixel tree into my SuperStar. It is defaulted to 50 pixels. I change it to 25 pixels. Everything seems to be working fine. But when I first started sequencing. I had left it on 50 pixels on the import screen. However, when I imported using 25 pixels the grid has a count od 24 long and 24 down. I assume that is what I need to be using. The sequence seems to work no matter with I used (25 or 50). I have changed and saved all my sequences to use the 25 pixel setting. I hope I'm doing it right.

On the 50 pixel setting, the top half of the  grid is brighter the the bottom half. So I have moved all my morphing to use the top half of the grid. But with using 25 pixel setting, I don't have the bottom light grid showing. But as I said, the sequences seemed to work in either setting.

Am I right to import my visualizations using the 25 pixel setting?

 

Thanks

I think importing the visualization using the 25 pixel setting will work best in your case. As you say, it will still work with a variety of settings, so the bottom line is to use the one you like best.

Is there a limitation to the number of controllers you use on a single network? In some of the tutorial videos I see people using aux networks etc. I am ramping my show from 6 standard controllers to 12 standard controllers and 12 RGB controllers and want to make sure I am planning properly.

If you are using 115K speed I recommend no more than 6 CCRs on a network. If you use the new 500K speed you could put 24 CCRs per network if you want. But I would recommend sticking with 6 CCRs per network even using the 500K speed. The only cost to adding a network is the cost of the USB485 adapter and the cost of another cat5 cable going from your computer to the controllers. The extra performance is well worth the cost and effort.

 

As for standard 16 channel controllers. You can put at least 20 of them on one network. So in your case I would recommend putting all your standard controllers on a network. And then using Aux A and Aux B for your CCRs.

 

Note that if you use the new 500K speed on your CCR controllers, you need to update the firmware on each CCR controller, and if some of your 16 channel controllers are not gen3 you cannot use 500K speed on them. So it is a good idea to have your 16 channel controllers on a different network than the CCR controllers, then you can set the 500K speed on the CCR networks and keep the network for the 16 channel controllers at the speed you are using now.
