In a world where running and technology collide, Nikodem Bartnik, a passionate runner and maker, embarked on a unique project that combined his hobbies and resulted in an ultrasonic race timer. Picture this: a device positioned at the finish line, mounted on a tripod, ready to capture the moment you cross the line, all controlled by an iRobota Nano. The small speaker signals the start of the race, and user feedback is displayed on an ePaper screen. Buttons allow you to adjust the distance from 50 meters to 1 kilometer, making it versatile for various races.
Nikodem’s Inspiration: A Fusion of Passions
Nikodem’s journey to creating the ultrasonic race timer began with his love for running and his fascination with electronics. He envisioned a device that could accurately measure his running time and provide him with valuable feedback. Drawing inspiration from his maker background, he set out to build a race timer that would not only be functional but also portable and user-friendly.
Ultrasonic Technology: The Key to Accuracy
At the heart of the ultrasonic race timer lies ultrasonic technology, a method of measuring distance using sound waves. Nikodem utilized ultrasonic sensors to detect the runner’s presence at the starting and finishing lines. These sensors emit high-frequency sound waves that bounce off objects and return to the sensor. By calculating the time it takes for the sound waves to travel and return, the device accurately determines the runner’s distance and time.
User-Friendly Design: Simplicity at Your Fingertips
Nikodem recognized the importance of user-friendliness in his race timer. The device features an intuitive interface with buttons that allow runners to adjust the distance and view their results. The ePaper screen displays clear and concise information, ensuring that runners can easily understand their performance data. Additionally, the race timer’s compact design and portability make it convenient to transport and set up at various locations.
Open-Source Spirit: Sharing the Knowledge
In the spirit of open-source collaboration, Nikodem has generously shared the code for his ultrasonic race timer on GitHub. This allows other makers and enthusiasts to explore, modify, and build upon his work. Additionally, 3D print files for the enclosure are available on Thingiverse, enabling anyone with a 3D printer to create their own custom race timer.
Bonus: Tips for Runners and Makers
For Runners:
- “Practice makes perfect.” Consistency is key to improving your running performance. Set realistic goals, stay motivated, and keep pushing your limits.
- “Embrace technology.” Wearables and fitness trackers can provide valuable insights into your running performance. Use them to monitor your progress and make informed adjustments to your training.
For Makers:
- “Don’t be afraid to experiment.” The world of electronics is vast and full of possibilities. Embrace your curiosity and explore different technologies to bring your ideas to life.
- “Share your creations.” The maker community thrives on collaboration and sharing. Share your projects, document your journey, and inspire others to explore their creativity.
In conclusion, Nikodem Bartnik’s ultrasonic race timer is a testament to the power of combining passions and skills. Through his ingenuity and dedication, he has created a device that not only fulfills his personal needs but also contributes to the wider maker and running communities. Whether you’re a seasoned runner looking to improve your performance or a maker seeking a new project, Nikodem’s race timer is an inspiring example of how technology and creativity can come together to create something truly unique and valuable.
