    I was about to comment that I also made a small LED panel, but then realized it was me.

    Here's the latest LED thing I'm working on (the design isn't mine): https://immich.home.stavros.io/share/oXerU8gnLn-dNHunPOg8lM8...

      How did you connect the individual smaller LED panels together? I guess the cool color patterns and the individual addressing comes from WLED then?

      Do you know if the panels can be bodged to be non square? There shouldn't be a lot of fancy wiring to screw up if it's all WS2812. Can you (delicately) chop a few LEDs out and bridge the connections?

      (hoping I have seeded this idea, so I'm not the first one to attempt this)

      Jokes aside this is super cool. I always find LED panels really interesting to look at under the hood. I’m so picky about the ones I like to use almost purely based on vibes when filming. They’re just one of those things that you immediately know you’re going to love or hate in post the moment they hit your subject

        What can I say, I'm addicted to LEDs. I tried so hard to not make that cube above, but I failed.

    On the topic of small LED panels, Jason of Evil Genius Labs has been making some really small LED panels [0] with addressable 1mm x 1mm LEDs (yes, individually addressable AND only 1mm on each side!). Fitting 128 onto a 1" circle is pretty sweet.

    I keep meaning to design some PCBs with them [1] but it's too far down my ever-growing list of projects to see the light of day...

      Why are you doing this to me

    I have a bunch of these 8x8 panels on their way from AliExpress right now for an art project that a part will look remarkably like the video. V1 will probably be a 32x32 just like it.

    I still haven't decided if I want to have a partition grid between the panel and the diffuser to make square edge pixels. It's definitely going to have a rp2350 inside. PIO is the best thing ever.

    The diffuser really makes this. The resulting effect looks great.

      It really did! It looked much better than I hoped, I really liked the result.

    This is neat! Any notes on the algo for controlling the output of the ws2812s?
