Answered Pixel Wiring Advice

Morning

I'm currently trying to convert some large Solar powered white Garden Balls to pixels

I have gotten some WS2811 PCD boards


My question is.... I want to mount 2 of these per ball... now I would like to know if i can split the Data coming in so they are both just 1 pixel..

Now I know I can use my F16v3 and just do grouping / virtual strings But i'm hoping there would be away to avoid this
Could I split the Data coming in to the start of both pixels but then only come out of 1

Thank you brains trust

You "shouldn't" have any trouble doing this. If you are running longer distances between "pixels" then it might present a problem but if under 10m from F16 and less than 3-5m between pixels you should get away with it.

Why not use Dumb RGBs?

Thanks Alan

Maybe I should add some null pixel buffers to help.... now where can I get those

Hey DJ

That would mean 12x 4 core cable runs back to my controller....

Plus during the off session these will be in my garden running off a PI

If I can’t make to it work, I’ll just go with one

I'm wondering why 2 per ball?
I used these https://www.aliexpress.com/item/42m...s-inside-20pcs-a-string-IP68/32640399824.html
which fit 1 snugly per ball and they are quite bright, or (dare I say it) are you balls bigger than mine? I used the Reject Shop ones.

Hey Oz
I made up some with reject balls


The big ones I have are 30cm ones from bunnings

I would suck it and see whether you need them. Easy to add after you've knocked a couple up to try. Link on my signature to my website and I have lots of the nulls in stock. They will definitely allow you to drive into 2 parallel pixels.

Well I kinda went another way.. I needed to order some more bits from ray so also order some 3w 2811 leds.... 1 of those per large ball ... much easier
