“Mystic Merkaba” is a light sculpture inspired by sacred geometry. Sound-reactive, 3D-printed, with 1,080 addressable LEDs. I originally built this in April-May 2019 as a group totem for EDC 2019, then refined it and brought it to camping trips, parties, and Burning Man 2019.
- 1,080 individually addressable LEDs in 36 acrylic tube segments
- 16 3D printed connectors + electronics box + battery box
- Aluminum pole extendable to 10ft (max totem height)
- Can be held as a totem, or stand alone with collapsible carbon fiber legs in the field. Attaches to optional base for more stability.
- Disassembles to fit in carry-on size suitcase for air travel
- Raspberry Pi 4 + Teensy 3 + OctoWS2811 driver
- Custom 211 Watt-hour Li-Ion battery pack (6s2p removable 21700 cells to enable TSA travel)
- Custom Python+NumPy rendering engine, and Teensy firmware for streaming pixel data
- All effects are parametric and can be randomized.
- Wi-Fi connectivity + Web UI for interactive adjustment of parameters
- Modes include:
- Sound reactive effects with frequency bands
- Beat synchronous (BPM-based) effects
- Color modes: full RGB effects, and grayscale mapped to color palettes
- Addressing modes: polyhedra parts (large/small tetrahedra + center octahedron), linear segments, volumetric (xyz), spherical projection
- Compositing modes for layering multiple effects (base colors + mask)
- Playlists for pre-selected effects, or full randomization
