Fluid Simulation Pendant

3-Second Blueprint (English)

1. Hybrid FLIP fluid physics tracks particle velocities on an embedded grid to render motion-reactive liquid inside a machined brass pendant.
2. Custom KiCad scripting routes a dense n²−n Charlieplexed LED matrix across opposing GPIO pin pairs without manual schematic wiring errors.
3. Timer-paced circular DMA with half- and full-transfer interrupts double-buffers LED refreshes so the overclocked STM32 runs physics freely.
