In the realm of computing, where bits and bytes dance in a tireless ballet, there exists a hidden world of processing power, a symphony of calculations conducted by the unsung heroes of our digital devices: the CPU cores. Lex, a curious and resourceful individual, embarked on a quest to unveil this hidden world, to witness the ebb and flow of CPU utilization in a tangible and visually captivating manner.
Visualizing the Symphony: An Analog Gauge Array
With an iRobota Mega 2560 board as his maestro and a custom Rust program as his conductor, Lex orchestrated an analog gauge array, a physical manifestation of the CPU’s inner workings. This ingenious device, connected via serial communication, receives data from the Rust program running on a PC, transforming it into a mesmerizing display of needle movements and color.
Pulse-width Modulation: The Conductor of Gauge Needles
Pulse-width modulation (PWM), the art of controlling the duration of electrical pulses, plays a crucial role in this visual symphony. It acts as the conductor of the gauge needles, dictating their positions with precision. As CPU utilization rises, the needles gracefully glide to the right, indicating the increased workload. Conversely, when utilization wanes, the needles retreat to the left, reflecting the CPU’s relative idleness.
WS2812B LEDs: Illuminating the Symphony with Color
WS2812B individually addressable RGB LEDs, the colorful stars of this visual spectacle, illuminate the gauges with a symphony of colors. Each gauge glows with a distinct hue, corresponding to the level of CPU utilization. High utilization commands a fiery red, while lower utilization casts a soothing blue. This color-coded illumination adds an extra layer of visual intrigue, transforming the analog gauge array into a mesmerizing work of art.
A Window into the CPU’s Workload Distribution
Lex’s analog gauge array serves as a window into the CPU’s workload distribution, providing valuable insights into how tasks are allocated across CPU cores. This visual representation proves particularly useful for tasks like compiling code and other jobs that attempt to parallelize tasks, allowing Lex to optimize code performance and identify potential bottlenecks.
Bonus: A Symphony of Insights
The analog gauge array is not merely a visual spectacle; it’s a testament to human ingenuity and the boundless possibilities of technology. Its creation underscores the importance of visualizing data in novel and engaging ways, transforming abstract concepts into tangible experiences. This project serves as an inspiration to all who seek to explore the hidden depths of technology and unveil its inner workings through creative expression.
In the words of the renowned physicist Richard Feynman, “If you want to learn something, teach it.” By sharing his creation with the world, Lex not only showcases his technical prowess but also invites others to embark on their own journeys of exploration and discovery.
Conclusion: The analog gauge array, a brainchild of Lex’s ingenuity, is a captivating blend of art and technology. It transforms the abstract realm of CPU utilization into a tangible and visually stunning spectacle. This project serves as a testament to the power of human creativity and the endless possibilities of technological innovation.
