Hi, everyone. I’m super excited to share my fireplace project, it came out even better than I imagined. So I moved earlier this year and the new place has a non-functional fireplace that the previous people painted black because….I have no idea. I think they thought it made this 1960’s bungalow look modern or something. Anyway, it was a big black thing in the middle of a room painted white and it was kind of an eyesore. But yanno what black is great at….being a backdrop for LEDs! And it just so happens that the grout spacing between the bricks was perfect for a typical addressable strip. So I got a pile of HDR SK9822 strips, designed a quick flex pcb with brick spacing to connect them all (because fffff snake wiring 23 strips), hooked up a Pixelblaze, and now have a super bitchin LED matrix in my living room. It’s 45 pixels across by 23 high, 1035 LEDs. I’m injecting power into 4 places, after 270 LEDs. The LED data is currently being entirely driven by one Pixelblaze Standard, but after 10% brightness, it starts to glitch. So I’m going to break it up and put a synced Pico in the middle. The 2D patterns look great, and I soldered up a sensor board so it’s also sound reactive. I also had to get the matchstick IKEA lamp so I could have it in the fireplace under the fire patterns. 
I’ve also got more build and action videos on my mastodon feed, starting here: Alpenglow Industries (Carrie): "Got an ugly-ass nonfunctional fireplace that some…" - Mastodon 🐘
I’ve still got some buttoning up to do, but this is one of the best things I’ve ever made. It’s really awesome to have a giant LED canvas in my living room, it makes me so happy. Many thanks to @wizard for helping me get the proper mapping and for poking around with adapting patterns. And many thanks to @zranger1 for making some really fantastic 2D patterns.
