    Yes, it looks like they did it the correct way .. So the addressing is sequential from top to bottom on each drop. My next frustration is the price. They ended their presale prices on Jan 30th !

    Since all of the vendors go to a very small number of actual companies in China, I will bet there are others who would offer the pixel icicles like these.

    The icicles wired so each drop is a pixel are also VERY interesting. You would not have the vertical part of the matrix in your sequencing. But the color sweeps and movement across the ice look nice (and a lot less channels to mees with.

People have been asking for this for a while, but so far nobody has come up with a simple way to do it. You can fold
    This is what I don't understand. The data is the only part that is serial, the power is just a bus. Ray or any other manufacturer should be able to take a 2811 node along with 4 pin cable and route the data back up and onto the next line. This would seriously reduce any extra lengths of wire:

    As I veiw the problem, they would need 5 conductor wire on the drops, so the data wire can get carried back up to the top. The manufacturers could do that, but introducing changes to a mass production process adds the majority of the cost. This is why the Seasonal Entertainment versions cost nearly triple over a plain old pixel string.

    You would only need 5 if you have a 4 wire pixel. Using WS2811 as a 3 wire pixel, your 4th wire would be a data return. No clock signal on the WS2811's.

    Ooops good catch. It's hard to concentrate when I am at work ! most pixels are 3 wire these days. The bottom line is one more data wire return, to keep the addressing sequential. I suspect that the vendors will create their own standard for these. And they will always be more expensive due to the extra care required for the wiring. I would probably still try to work itout with common pixels, if not exactly like what Peter did.

    as I think about Paul's house compared with Peter's house, Paul would need the icicles to appear longer due to the larger house. So a larger spacing between bulbs would help, or use more bulbs .. somethine like 7 or 8 bulbs deep instead of 5.
