In a world where traditional clocks are often overlooked, 22-year-old Dutch designer Yvo de Haas has introduced a truly unique timepiece that stands out from the crowd. His "Hand-in-Hand" clock, designed using 3D printing technology, has captured the attention of tech enthusiasts and creative minds alike. What makes this clock special is its unconventional design: the minute hand is not separate from the hour hand but is instead attached to its end, creating a visually striking and functional time display.
Yvo, a self-taught electronics enthusiast, has always been drawn to innovative projects. He mentioned on his blog that he lost a clock during a move and wasn't satisfied with standard options. While he had previously built LED clocks, he wanted something more mechanical. This led him to create the "Hand-in-Hand" clock, an idea he had been thinking about for years. In fact, he first came across the concept five years ago through a classmate, and three years later, he decided to bring it to life.
The project, which took around 10 hours to print using a 3D printer, consists of 16 different parts. Yvo shared the design as an open-source project, making it accessible to anyone interested in building their own version. You can download all the STL files and code from his blog, allowing makers to recreate this unique clock at home.
Assembling the clock, however, requires some technical know-how. The list of components includes a stepper motor, a driver, an Arduino-compatible microcontroller, power supply, resistors, bearings, and various fasteners. While the individual parts may seem simple, the assembly process can be complex, especially for those new to electronics. Yvo emphasizes the importance of following his detailed tutorial closely.
He used a prototype board rather than a PCB, which means there's no pre-designed layout to follow. However, he provided a schematic that should make replication straightforward. For the circuit, he connected the 9V or 12V power supply to the microcontroller’s VIN or VBAT pin, while the 5V output came directly from the controller itself.
What makes the "Hand-in-Hand" clock truly unique is how it operates. Instead of tracking actual time, it uses the consistent intervals of the stepper motor to move the hands. While these intervals don’t necessarily align with real time, the accuracy remains sufficient for practical use. It’s a clever and artistic take on timekeeping that blends engineering with creativity.
This innovative design is more than just a clock—it’s a conversation starter. Whether placed in a modern home or a creative workspace, the "Hand-in-Hand" clock adds a touch of ingenuity and style. For anyone looking to explore 3D printing and electronics, this project offers both challenge and satisfaction.
