I’ve just been lying on my couch watching pretty lights for the past several hours. It’s a little over half wired and may need either power injection or a beefier power supply or both. It’s at 540 LEDs and works well at 10% brightness but the upper rows start to lose blue at 25%.

I figured out after soldering the headers for the layout shown previously that I could have stacked it vertically pretty easily for a smaller footprint. Like so:

I’m using one of my Pebble Buddy 4 boards even tho I’m using a standard Pixelblaze for this project. It’s handy because it adds a USB-C connector for power, and power to the LEDs isn’t routed thru the Pixelblaze board (so maybe I can drive more LEDs than if I was using the onboard USB micro connector.) It also adds a connector for the first strip, so I can easily detach the PB if I want to use it for something else or add a sensor board to it.

The idea is that I can bend it around the corner and tape it down.

This is the custom flex circuit I made to connect each row to the next. It was also an excuse to order a clear flex PCB from JLC. It sokders directly to the addressable strips and is one brick in spacing.

This is gonna be so good! This pattern is Marching Rainbow.

3 more rows up! The right ones are harder for me to solder because I’m right-handed and the angle is funny. Also I really wish I had thought to bring my head-mounted magnifiers from the shop.

@wizard The two rows running KITT, always my first pattern to make sure i have the LED setup and color order right. Don’t mind the loud music and me excitedly yelling.

Got an ugly-ass nonfunctional fireplace that someone painted black? I’ve got the solution! I’ve had the parts and custom flex boards for a while for this and just no time. Tonight’s the night! Powered by a @wizard Pixelblaze and their HDR strips. It’s gonna go all the way up the fireplace!
