Hi and thanks for the great forum!

This is my first year with a light show, so I'm starting with a conservative setup (Arduino Mega controlling 100 WS2811 pixels in the form of a spiral tree with star topper and 32 relay channels to switch standard LED light strings using Vixen 3). After quite a bit of effort, it looks like I've finalized my Arduino code so I can concentrate on learning how to use each Vixen effect for my pixel tree (the relay channels are the easy part since they're just on or off)!

We should talk. I am also building arduino ws2811 controllers. Trying to drive 640 channels using parallel output to up to 8 strings of lights listening to up to 8 universes. It works well except my w5100 network card can't keep up. It will reliably receive 3 universes but the rest get dropped. I am currently waiting for some w5200 Ethernet cards from China with better Spi, burst mode support and twice the buffers to see if that helps. My arduino code has a couple of assembler routines for issuing the ws2811 data and transposing the e1.31 data into the ws2811 format so I can bit bang it out to 8 lines at once.
