I see that the discussions are picking up on the using DMX and RGB or digital smart pixel strips. It appears from what I have read so far that for the "intelligent" pixel strips that there are 6803 controllers chips (which is what the LOR CCR's use) and a 2801 controller chips. I am not up on the protocols or implementations of either of these chips but am curious as to what are the advantages or disadvantages between them? Or are there other chip controllers out there that may be better suited towards the ultimate goal of using the intelligent pixel strips with LOR? I was scanning through Ray Wu's site last night looking at some of the 262 pages of LED strips - Boy! Needless to say that now I am somewhat enlightened and more confused than ever.  This is all new for me but so interesting as to the possiblities that it offers us for really insane lighting displays. It will be great to hear from those who are actively using or testing these now as to how they work. Thanks Bill

Awwwwww Shame on you Bill you didnt watch all the videos I posted did you. LOL One of them goes into great depth on the different chips and what they mean as well as a good clip on the fading difference and why that happens. It's this one I believe........ http://vimeo.com/19367640 Last edited on Sunday December 18th, 2011 01:08 pm by harrison0550 |

Oh man, I'm not worthy.  Sorry about that. I am meaning to go watch them though. Just got to excited and caught up in this I guess. Bad Bill, Bad Bill !!!! I'm going back to my basment now and reflect on my actions and unbridled haste at jumping ahead of things. Well actually I am building a couple of candy cane spinners this morning as I found 16 candy canes that I had forgotten all about last night under a spare bedroom bed! But I PROMISE to watch the videos and keep quiet till I have absorbed more (more what I can't say at this point )

I just watched a couple of the videos and my head is spinning. Hey Bill, put down the canes and watch the videos, you won't need to build the spinner!

Yea, I know. But the spinners are kind of fun and I have the things to do them without having to spend any money (which I don't have any of anyway!). So just to prove that I have actually been working this morning, here are a couple of pictures of the spinners so far. I only need to cut a couple of more pieces of wood for stiffeners and mounting points and these will be good to go. See being a bored and depressed person sometimes has advantages for me !!

Thanks Nothing fancy or elaborate like pixel strings, but at least it is 2 more elements to put out there and say "Hey look, I added more blinky stuff!". LOL Okay, back to work and then I will watch some videos.

Just to get back to some real on topic data here : I have both. The 2801 chip is better technically speaking. 6803 has a max of 256 shades of grey or 15 bit color vs 24 bit color on the 2801. The more levels you have, the more colors you can make. For me its really not an issue because I'm not looking for 16 million colors - In fact I usually just want Red, Green, Blue, sometimes purple and white, but really dont use the rest of the spectrum. How bright your actual light is depends more on the LED than the driver chip. They both work well, and they both are easy to convert to DMX.

This is what I believe is the actual difference between 6803 & 2801 based on my searches. Please correct me if wrong: 6803 5 bits per color (32 shades per color/32,768 colors) 2801 8 bits per color (256 shades per color/16 million colors)

And it makes a big difference when dimming. The CCR is a 6803, but the controller makes it act more like a 2801 as far as dimming goes! Donny

There are a couple discussions where LOR John commented about the CCR and it's magical use of the 6803 to create more colors than it's capable of... Post A Post B You need to scroll down to his posts, and there are multiple comments on both. If you're using raw DMX to control a smart strip, you need to purchase one that is capable of making use of all 256 step of dimming available with DMX programming enabled in the Sequence Editor. My sig has a link to David Moore's Vimeo page. Good stuff to ponder in there... Jeff

Light O Rama needs to make controllers available for different pixel modules and allow for user customization such as the number of pixels per controller and the type of pixel node that is being used. Example a user may only need 30 pixel nodes for a wire frame or to go around a window. In another location, 40 nodes or 10 nodes. Often pre-made pixel sets are either too long or too short and sometimes not useable for a given application.

I have watched dmoores demo on the chip comparison but was wondering if anyone has done a side by side comparison of these two chip types in a ribbon? I'm just trying to wrap my head around the dimming differences between these two chips. I am on the fence as to which to use for my arches. Thanks greg

Hi Steve If you look close you will see the cords and plugs hanging down the back side. These are the standard mini lights style candy canes. Nothing fancy. I had picked them up from a dollar store on an after Christmas sale day a couple of years ago. I just happened to find them hidden under a spare room bed while doing some searching and thought that it would be a nice quick project to make the spinners with them. They worked good for the display so now I want to make them bigger and double the amount of canes on each one! Though I have thought that I may use some 2 color (red and green) rope light to make extra sections in between each set of candy canes. Only trouble would be that it would make each spinner use 16 channels! Yikes! But it would look pretty cool.

I'm just trying to wrap my head around the dimming differences between these two chips. Why yes, I have in fact. HD video taken in full 1080P on my wife's Cannon EOS Rebel T3i doesn't show the subtle differences even in different levels of light in the room. It's almost full daylight in the room with all the curtains open as it faces south and the sun is low in the sky and shines right in. All the way to full dark, you just can't see the difference on video. The LEDs are too bright. I'm not knowledgeable to choose a filter to help, so I just gave up trying to capture it. What I did was take both ribbons, the 2801 is 60 pixels or 36 LEDs per meter, and the CCR is 50 pixels or 30 LEDs per meter so I treated them as dumb strips and dimmed every pixel at the same time. I created both devices in an animation and copied color fades and dims using combinations of color and individual R, G and B then full white identically across both devices. You can see steps with the CCR, you have to really look for the steps with the 2801. The colors of the 2801 just look better to me. A color fade has richer colors. ...and that's just my 2 cents. Jeff

Jeff, Would you say it is worth a $250 price difference between the two. I usually don't use a long dim on my arches and that is what I am looking to replace. Put it this way I would like to get the 2801's but then I need to cut something else out of the budget as per the wife.  Still debating on shich route to take.

I don't get your question, however I don't have all the facts. The CCR is a $250 investment, $200 or so during the sales but they're usually gone in under 3 minutes. A USB485 adapter is inexpensive and will provide DMX to a ribbon adapter. The Ray Wu store has WS2801 adapters and controller combos for around $120. A 12VDC power supply on eBay that could power 3 of these strips is $20 to $30. The only thing that could account for a large difference in price is an upgrade to S3 with DMX enabled, and Superstar too?... Jeff

Jeff, Sorry should have been a little clearer. The comparison I was looking for was ray wu's between 6803 and 2801 strips, not the CCR. The price difference on his site for me is about $250 between the two with what I am looking at getting. Sorry for the confusion.

You don't want to purchase the 6803 strips from Ray Wu if you intend to control them with a DMX adapter. The 6803 strip is 5 bit color. A CCR controller cheats a 6803 into believing it can produce color it can't produce. David Moore demonstrates this in his Vimeo videos for Holiday Coro by showing that an 8 bit ribbon like the 2801 has 8 steps of dimming before a 5 bit even turns on. I think it equates to 256 steps for the 2801 and only 32 for the 6803. So an LOR sequence would only have 32 intensities for 100 steps. A very limiting choice. You wanna talk about seeing the dimming step? The 6803 will step real ugly without a CCR controller... Jeff
