Here’s a great project by Walt aka alishl06 from the adafruit forums:
A BIG THANK-YOU to Adafruit for the plans to build the Video Wall. I built one and integrated it in this year’s Christmas Light Show. I put it inside the Wreath. Look close! https://www.youtube.com/watch?v=OqVRfI24wBw
A Raspberry Pi handles the Videos. I built an interface that goes between my Christmas Light Controllers and the Pi to specify which Video the Pi has to run. The Raspberry Pi I am using is the one I got for free when I ordered the parts for the Video Wall!!!
Thanks for sharing this, Walt! Keep up the awesome work!
