[QUOTE="RoChess, post: 1217933, member: 18896"] You can do the exact same thing as me then. I simply have HTPC that runs a USB cable to Arduino Leonardo, which runs 2-wires to WS2812B light-strip, which is powered separate by a 5V/10A brick. No soldering was required, and the main struggle ended up finding Arduino code that worked (and switching from pin 4 to pin ~11). On the HTPC I use AmbiBox software and it has been working awesome. So your only issue is finding a Linux version of the [URL='http://www.ambibox.ru/en/index.php/Main_Page'][B]AmbiBox software[/B][/URL] that will allow you to specify capture zones on the screen that will drive each matching LED. If you want to use different LEDs then you might require additional components to drive them, or at the least different Arduino code to control them. Should not be difficult, from a quick Google search I can see AtmoLight plugin for VLC working just fine on Linux, and I'm sure a standalone version like AmbiBox, or an integration with your Linux media solution (Kodi/Plex/etc) exists somewhere. The reason why I was forced to abandon Hyperion solutions that would work stand-alone for any HDMI device, and not just for HTPC, is that no 4K support exists for the frame-grabber that is required for the Hyperion to understand what LEDs require activation. If one ever arrives I can always convert what I have now over. As for photos, as linked above, I've only made them of the aluminium angled diffusers that I taped to the back of my TV to hold the LED strip, and did not take photos of the 3D printed box that the Arduino is in, or a video of the final results. What I like about the diffuser strips taped to the TV with special 3M strips is that I can remove everything without leaving a single trace in the future. Will see if I have time this weekend to make a video, though in the end it will be pretty much be identical to all those other videos on YouTube, and I do not have a 4K camera to capture the 4K output anyway.
