I received this brilliant LED triple helix, a gift from @graemegets! 🤩
This was from a gift exchange with a small group of maker friends. It came with 450 2mm LEDs on three thin strips, driven with a #PixelBlaze by @wizard.
More details 🧵👇

1. A dark 3D printed triple helix with a very thin strip of vibrant RGB LEDs on each helix arm. The LEDs are pulsing smoothly between different colors. The cylindrical helix is completely hollow inside.

  @graemegets @wizard much better, it's now wireless, with a built in lithium battery and charger.

  @graemegets @wizard I am pleased to announce that I have mastered gravity! ⏳😁

  1. The same LED triple helix described in the previous posts in this thread. In this video, the helix is tilted back and forth. The LEDs that are lit change in response to the tilt, making it look like the contents of the helix are falling due to gravity.
  jwhevans repeated this.

  @graemegets @wizard I had to blast some Mega Drive, of course. 😁

  @graemegets @wizard the output expander also includes a microphone, so here's a selection of audio-reactive patterns. 🔊

  1. A video of the same LED triple helix as described in the previous two posts in this thread. In this video, the LEDs pulse in response to the music being played. Several different audio-reactive patterns are shown, each of which respond to the music in different ways.

  @graemegets @wizard Of course I immediately cracked it open and added a sensor expander to the #PixelBlaze. I also set out to get it fully mapped in 3D. The combination allows for motion-sensitive patterns like this.
  Later I hope to make this more granular than just up or down, with a smooth particle physics simulation. ⏳

  1. The same 3D printed LED triple helix described in the previous post in this thread. In this video, the LEDs are simulating sparks falling from the top towards the bottom. I reach in and pick it up, and rotate it so the top is now the bottom and vice-versa, like an hour glass. The simulated sparks reverse direction, so they're always falling.
