Concentric Rings/Circle Mapping

[Scruffynerf]

I’m going to move discussion of the above very cheap string to it’s own thread, due to some technical questions.

Timing of a cheap strand?

As discussed in Concentric Rings/Circle Mapping I found a very inexpensive set of 200 “fairy wire” addressable lights. I took the strand and attached it to my PB. the 3 wires are V+, G, Data. NOT V, D, G as usually found. I confirmed this. it’s RGB order perhaps it’s the 200 pixels, without added power at the far end (that’ll be my next trial but this was a quick and dirty setup), but it seemed VERY sensitive to timing: It seemed to prefer 333 and will light them all, but pixel 1…
