Introduction
For many, graduation ceremonies are a solemn occasion, a milestone marking years of academic effort. But for Eric Park, a tech-savvy student, this moment took on a unique twist. Instead of simply walking across the stage, Eric opted for a project that transformed his ceremony into an impressive technical demonstration: a graduation cap running Rust.
Why Rust?
Rust is a programming language known for its safety and performance, crucial qualities in embedded systems development. Eric chose Rust for its ability to efficiently manage memory, avoiding common errors that can occur with other languages like C++. By using Rust, Eric ensured that his project would function reliably during the ceremony.
The Project Components
Eric's project involved several hardware and software elements. Here are the key components used:
- Digispark ATtiny85: A compact microcontroller, ideal for embedded projects.
- 48 WS2812B LEDs: These programmable LEDs allowed for dynamic lighting effects under the cap.
- Reed switch and magnet: To detect tassel movement, triggering the light animation.
- USB-C Power Delivery trigger board and power bank: To power the entire system.
Challenges Encountered
The development of this project was not without its obstacles. One of the main challenges was that the avr-hal and ws2812-avr libraries did not support the ATtiny85 out of the box. Eric had to fork and modify these libraries, including setting the default clock speed to 16 MHz.
This experience illustrates the learning curve often encountered when using Rust for embedded projects, but it also demonstrates the language's flexibility when used creatively.
The Final Result
Although the project took about five hours to complete, the result met Eric's expectations. However, he admitted that despite the ingenuity of the project, wearing it during the ceremony would have been "too flashy." Thus, the idea remained a personal engineering project rather than a public statement at the ceremony.
Conclusion
Eric Park's project shows how technology can transform traditional moments into unique and memorable experiences. For developers and tech enthusiasts, it's an excellent example of how Rust can be used innovatively.
