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.

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!

We’ll be bringing all of these to Maker Faire Bay Area next weekend! They can be finished as a necklace, fish hook earrings, or lobster claw earrings for hooking onto hoops, your choice. #glowies #alpenglowies #ledjewelry #makerfaire #mfba2025 #makerfairebayarea

Production today starts with a little dip in some conformal coat to insulate the exposed pads and wires. #glowies #alpenglowies #ledjewelry
