@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.

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. 😆

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

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.

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

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.

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’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 liked the patterns the dark space made in this one. No mapping has been done yet, this is just a result of the snake-like wiring.

Behold! It is now sound reactive. (sound on).

I finished installing the LEDs today! The soldering was more awkward than I thought it was going to be, especially as I got higher. I started soldering two strips together on the right side, (the more awkward side for me) on the floor, and then taping them up together.

The last bit of attaching the boards and power on the right side, and soldering the custom flex circuits on the left side. I then realized that all my little USB power supplies were weaksauce and having a hard time supplying enough current. I ended up running to my shop and grabbing a beefier USB power hub.

Success! All 4 sections of strips are working!

Now the fun begins. @wizard Pixelblaze running Xorcery 2D.

@wizard Pixelblaze running Eye of Sauron. This might be my favorite pattern.
