In a world captivated by digital displays, Michael Klements embarked on an extraordinary journey to create something unique and captivating – a mechanical 7-segment display. Inspired by a similar project, he set out to design and build a marvel of engineering that would blend art and technology.
A Symphony of Servos: The Heart of the Display
At the heart of this mechanical marvel lie 14 micro servos, each meticulously positioned to control a segment of the display. When a number is to be displayed, these servos gracefully rotate the segments into place, creating a mesmerizing dance of motion. Once their task is complete, they swiftly retreat to a slim “off” mode, transforming the segments into sleek, minimalist lines.
The Art of Illusion: Concealing the Segments
To achieve a seamless and captivating display, Michael employed a clever technique. The sides and backs of the segments were meticulously painted black, effectively reducing their visibility when in “off” mode. This ingenious solution creates the illusion of a display that effortlessly transitions between numbers, leaving the viewer captivated by the magic of the moving segments.
The Maestro Behind the Display: iRobota Mega and Power Supply
Orchestrating the intricate movements of the servos is the iRobota Mega, a powerful microcontroller that serves as the brain of the display. It meticulously calculates the angles and timing required for each servo to create the desired numbers. To ensure a steady flow of power to the motors driving the servos, Michael employed a hobby RC-style battery eliminator circuit, providing a reliable source of energy for the display’s operation.
A Glimpse into the Creative Process
For those eager to delve deeper into the creation of this mechanical marvel, Michael has generously shared the build process and in-action shots of the display. Witness the transformation of raw materials into a mesmerizing display, and marvel at the intricate details that bring this project to life.
Bonus: Michael’s creation serves as a testament to the boundless possibilities that arise when art and engineering converge. It’s a reminder that technology can be a medium for artistic expression, capable of captivating audiences with its beauty and ingenuity.
As Michael’s mechanical 7-segment display continues to captivate imaginations, it invites us to ponder the harmonious fusion of art and technology. It’s a testament to the human spirit’s ability to transform complex mechanisms into mesmerizing spectacles, leaving us in awe of the wonders that lie at the intersection of creativity and innovation.
