Flip-card is a project that combines hardware design (using Raspberry Pi RP2350 as the main controller, 21*22 LED matrix) and software implementation, aimed at displaying fluid simulation (FLIP) effects through a business card-sized device.
This project utilizes existing fluid simulation algorithms (FLIP) and hardware design, achieving high-performance firmware implemented in the Rust programming language, with all functionalities centered around the Embassy framework, which is also the most convenient way to get started with embedded Rust.

Project author: Nick Johnson
The PCB design files are located in the “kicad-pcb” folder, and the fluid simulation logic is included in the “fluid_sim_crate” folder.
In terms of details: the fluid simulation is based on Matthias Müller’s FLIP algorithm, and the rechargeable battery design references cnlohr’s tiny touch lcd project, with firmware optimized for the RP2350 microcontroller.

I previously recommended a fluid pendant project, a creative embedded project similar to this one, featuring a high level of completion.
