Answered Chopping or Adding to Pixel Strings

[Max Kabilafkas]

Is there any reason that I can't cut excess pixels from one string and add them to another? Assuming I manage my power requirements correctly.

as long as they use the same protocol then there is no reason as long as you as you say manage the power requirements

And remember that they are directional. They either have DI (Data In) DO (Data Out) or an Arrow printed on the circuit board.

I seem to recall a previous thread where a problem was encountered when the IC type changed even though their protocols were identical or nearly identical. For example a WS2812 to a WS2811.

Also just be aware some manufacturers use different batches of LED's which can result is some slight colour variations. This isnt a big issue for some props like house outlines, low density props, but with say a Matrix / High Density prop you may notice the difference.

I try to keep off cuts of pixels from the same order in separate bags in case i need to replace a faulty one.

Also note some 12v pixels have resisters and others have regulators, whilst will prob all work ok, maybe not best practice to mix and match these
