    One more question, could you use an Arduino (with an atmega328 chip nonetheless) so that it's made easier to program?

    Great. Really looking forward to try this out since I need some dimmer packs but they cost a fortune.

    Can this take a 220v input (europe)?

  • Nope, that didn't work. I'm finding this to be very strange. It is clearly a signal issue since it lights up red on a GRB string and green on an RGB string. It is just the first address/led that's doing this.

    I have tried connecting a string of ws2811s to a pixel pusher but the first pixel is keeping its red colour on all the time. I tried this with a WS2812 strip to the same effect. So if its meant to be black, it's red, if it's meant to be green, it's yellow. Did you face this issue and how could it be solved. What might this be?

    Yes I'm pretty sure the rc file is ok.I set it to be a ws2811, in grb (for the string light) and in rgb (for the strip) order. The string light turns its first led in red and the strip in green. Mine are already swapped. Are yours swapped or did you attach the pin to the data line without swapping? I swapped so I could have data next to ground (+ C D - instead of + D C -)I'll try unswapping it. Great instructable btw.
