I have systems driving 1000+ at a time... and have seen the evil that lurks :twisted:

Which seem to be as fast as 80 mhz. I have seen this number somewhere in the IoT example.
Maybe we can use this higher bitrate to modulate the ws2811 protocol.

I have just heard about Boblight. What a nice fantasy to have esp8266 handling all that.
