Ultrathin business card runs a fluid simulation (github.com)

Article summary

A business card has been created that runs a fluid simulation using a fluid-implicit-particle (FLIP) simulation. The card's design files and firmware are available on GitHub. The project is based on previous work by Matthias Müller and mitxela's fluid simulation pendant project. The card features a 21x21 LED matrix and a rechargeable battery.

What commenters say

• The project is an impressive example of a complex electronic device that can be built and assembled using modern manufacturing techniques.
• Learning physical simulations can be challenging, but there are many resources available, including online courses and tutorials, to help get started.
• The cost of building and assembling a device like this can be relatively low, especially when using services that offer PCB assembly and population.
• Hand-assembling a device with a large number of components, such as LEDs, can be difficult and time-consuming, but it is possible with the right tools and techniques.
• The use of surface mount assembly and pick-and-place machines can greatly simplify the assembly process, but may require specialized equipment and expertise.
• The project's design and firmware are open-source, making it possible for others to modify and build upon the design.
• The device's cost and complexity may make it impractical for widespread use as a business card, but it is an interesting proof-of-concept.
• There are many resources available for learning about physical simulations, including books, online courses, and tutorials, and it is a valuable skill to have in many fields.
