First an foremost.
Thanks for collaborating/sharing on a very fun and satisfying project! You helped this old Carpenter/Linux hobbyist put a bit of “bling” on his media center TV.
Linux frontend running xbuntu 14.05. (Ya needs an update)
Hyperion installed with Kodi 17 and the hyperion.kodi-master plugin.
Arduino Duemilanove w/ATmega328 driving a ws2812b strip w/250 LED's.
On a 65'' TV.
Just took a week of light reading. A quick fabrication of a suitable frame to hold the LED's. A bit of hot glue, solder and some wires. A head bang or two for dumb wistakes. And it works very well, and most important Looks Great!
No questions yet still reading and tweaking.
Just a Thanks.
