I've done a few projects in the past with led strips and the Teensy 3.2/OctoWS2811 shield with FastLED. I'm thinking of doing something larger and more complex, but not sure the right direction. Something modular and wireless, but each module is controlled via a single master controller, or interface.

Take an example of 2 independent (or more) light displays that are identical. Each has their own controller with identical code and can work independently, with various patterns. Now throw in a wireless option that can control both of them and sync them. So if you choose pattern 1, it will change to pattern 1 on both and run both in sync. Or, be able to trigger running pattern 1 on display 1 and pattern 2 on display 2 at the same time, etc.

It would also be great to somehow upload new patterns to the wireless units without reprogramming them. More of a plugin kind of thing, dynamically loading them like from a text file. Is that possible?

I noticed my holiday light strip located inside my front window is starting to flicker like crazy when turned on and during the animations. It seems like it's mostly during fades. The temps outside have been pretty cold lately - at or below freezing. After running for about 5-10 minutes the flickering goes away. Are these strips pretty sensitive to colder temps? I'm using 2812b's.

How many 2812B LEDs can a teensy 3.2 reliably drive using a single output port (continuous led strip) and a good level shifter (74HCT245)? I see numbers on the Octo2811 page but it doesn't mention if they are using all 8 outputs or what the config is to get at those numbers.
