Open Source Flip-Card with FLIP Fluid Simulation

This project open-sources a flip-card business card featuring a fluid simulation based on the fluid-implicit-particle (FLIP) method. It includes PCB design files (kicad-pcb folder), a standalone fluid simulation crate (fluid_sim_crate folder, based on Matthias Müller's work), a rechargeable battery design (inspired by cnlohr's project), a WASM simulator for debugging (sim_display folder), and RP2350 firmware (flip-card_firmware file). Further details are available in each folder's README.
