For power injection, do you need to run both a positive and negative wire from the power supply to the injection point? Or can you just run a positive line? If you have a negative running through the controller and through all the lights inline in that way wouldn't a negative line for each power injection be redundant and unnecessary?
When you show the diagram at 8:50, could you just ground PSU1 and PSU2 together? Also if you use the same PSU to power the pixels and the controller do you need to run a ground from the controller to the pixels?
power supple injection from the same supply would you not over load it. say 200 pixels at 2.5a but if you inject at the 100 point mark would that put the power supply upto 5amp. So ideally what supply is needed for current per strand
Man throwing shade on us Mericans! That's funny though. I think of Aussies as the grandfather of pixel lightning! In the end we all help each other. It's not a competition and we all bounce ideas off one another.
Question that wasnt answered here and I cant seem to find the answer, how do I split the data wire from the controller to multiple strips, as in 2 or more strips having a parallel data line instead of series?..... or are you not able to do that?
I believe you would have to have two data lines. Although an interesting idea if you could copy it in some way to split it for things you want to run the same pattern.
Need to know the max amperage of the power supply and then it will only run at 80%. So if you had a 5vdc 10amp power supply it will only be able to run continuously at 8amps. Think 5v pixels of 100 are roughly 3amps at max white but most run their shows at 20-40% brightness. If that all makes sense. Hope it helps!
Those EUROTRASH types hmmm your arrogance and ignorance shows.... at 10.45 that’s not a person that doesn’t it for a living us properly trained folks know better and the correct way.
2022 I'm not an electrical engineer, but this is crap. I just bought 60/m 5 meter strips so that is 300 pixels and the first pixel is no more white than the last one.
The us guys do it this way... we’ll maybe one guy. But that’s idiotic. I can probably find an Australian that does it that way too In all cases it depends on the specific scenario and application
Thanks for posting this, always good to learn new stuff in the light show world!

Great video and diagram !

8:50 PSU3, on the other hand, is vitally important!

I have 2 PSUs, how many pixels would you run maximum with that? Each have 2 outputs and my pixels are the ws2811 5V. Thanks in advance?

@9:00. Those Americans don’t think you have to hook up the negatives. Damn Americans
@10:45

You obviously have to tie the negatives together. That’s the case in all electionics. Otherwise the signal baseline moves.
I wonder if its because they are using multiple power supplies and dont want to connect the + to both PS together?
