    Hi All,
    I am planning my first synchronised display with a few thousand 2811/2812/APA102 pixels, several ESPixelSticks (home made using ESP-12 modules) and Vixen 3. Will also be experimenting with a homebrew controller(Arduino Due with FastLED or OctoWS2811, using an ESP-12 or W5500 ethernet interface). Hopefully be able to control a truckload of pixels)
    Anyway, I also have a ton of 31V AC lights (the ones with only 2 wires from the controller/plugpack) I bought in the post christmas sales last year (around 4000 leds). I was thinking of building the above controller fitted with several H-bridges (L298N - control up to 36V) to be able to switch polarity and have PWM dimming to get full functionality of the stings - but synchronised to my display.
    Has there been any prior work on a similar project, or am I pioneering here? Will be happy to share my experiences here if this is a new idea.
    Thanks guys...

    Thanks a lot for the quick reply! This is exactly what I am chasing. While it's a shame that I'm not the first person to think of this solution, it is nice to see that someone else has already done the hard work and has something I can just buy and not spend multiple weekens tinkering with. Nice use of a WS2803 - I would never have thought along those lines...
