• Unfortunately the video link points to https://example.com/docs
  • How do you get the flashing LED synced up to the spinning pinholes? Maybe the motor provides some positioning feedback so you just have to line it up once…
  • It's stunning. The video speaks for itself. Please scale this up, like way up back of a truckbed size. This would be delightful to see spinning and running IRL.

    Then get a grant and make one as wide as a city street

  • eat it hdmi
  • Okay, that is genuinely amazing.

    Love it, thank you for sharing and for being inspiring :-)

  • I can see this being applied to hubcaps in the future.
  • Absolutely fantastic!

    The video URL doesn't seem to be correct, through. ;)

  • about the same idea as nipkow disk

    nowadays when people don't want to go the rotating led bar way, which requires very high density led strips (hundreds of ~200-400 mil smd leds) and the accordingly complex control circuitry (basically an FPGA per bar + high speed bus, etc), they do nipkow disk but with individual leds instead of holes. this way you can get away with tens of leds while still having a reasonable sized picture and not that much bandwidth to drive it.

    edit: another, less sophisticated take is for example
