yeah complex is not great in my mind I like simple these things will work apparently to about 100 feet about 30m which is great and you chuck them in and forget about them , they're also slimline I used a pigtail on each end and 13mm double wall heatshrink to cover the board and 8mm heatshrink each side , shrink the 13mm first then slide the 8mm over each end and it's self sealing no silicone required and nice and tidyTrue. Alec does make Pixel Extenders which work pretty good, but are a lot more complex
I think it cost me about $67 AU for 20 of them delivered from memory so $3.35 each but I would have no problem if they were a little dearer as they just work so well and there's no having to put them in xlights or the controller , completely invisible and you can put them anywhere start of the string . middle , 3/4 way through no problem, they work with any string/strip you don't have ones for 2811 and another for a different chip it doesn't matter what chips you're usingI did a buffer PCB design a while back but never released it. Does that mean i should work out a price? What do the others sell for?
