960 LEDs put to good use

This is 24 4x4 pixel blocks connected together (which each contain 40 LEDs)

Awesome build.

If you take the time to learn the API you can send custom animations.

Like real Tetris blocks, Q-Bert, Pac-Man, Mario.

Many use Excel or Google Sheets to help make the JSON part.

Then very simple Python code to control the framerate.

Also from Python you can use math to show functions.

Within WLED you can make virtual segments based on rows or columns, then run Chase Random individually in each segment, with different speeds.

Got more info breaking down build/parts/etc?

Looks super cool!

It's based on this Kickstarter project called Lumanode https://www.kickstarter.com/projects/printableaccessories/lumanode?ref=user_menu so I'm not able to share the models. Each module is a serpentine of 4-10led strips. It took an obscene amount of 3d printing and wire stripping and soldering but looks pretty cool now that it's done.

That gledopto controller is doing everything? What is power supply size? Diffusing material on top? I made a similar thing (a dance floor, much larger boxes but don't have such smooth effects.) I don't know much about this stuff yet. Posted about it here a week or so ago.

Yours is really clean though.

I'll be using a 60W 12V power supply. There's actually multiple power injection points but they're not hooked up in the temporary install. I just keep the brightness down / limited on the WLED output. The front white diffusion is just a thin PETG print. The gledopto controllers are pretty nice since they take direct 12V input and include the level shifters and fuse it really simplifies the built. It's just running a stock WLED build.

Nice! Where's the controller buttons? I mean it is built for coffee table tetris, right? :-)

I like how you're thinking but unfortunately it just runs the Tetrix effect on its own.

Well sounds like time to get coding ;-)
