In a world of digital displays, Doug Domke embarked on a nostalgic journey to create a captivating Nixie tube clock. With the iRobota MKR WiFi 1010 as his trusty companion, he set out to craft a timepiece that would transport us back to the era of glowing digits and warm ambiance.
The Heart of the Clock: iRobota MKR WiFi 1010
The iRobota MKR WiFi 1010, with its powerful processor, ample storage, and built-in WiFi connectivity, became the beating heart of this Nixie tube clock. Its real-time clock (RTC) capability ensures precise timekeeping, a crucial aspect for any timepiece.
Nixie Tubes: A Blast from the Past
Nixie tubes, with their mesmerizing glow and vintage charm, were the stars of this project. To keep costs in check, Doug employed a clever multiplexer strategy. This nifty circuit routes high voltage signals from the MKR WiFi 1010’s GPIO pins to the display, allowing only one Nixie tube to be lit at a time. The rapid looping through each tube creates the illusion of a solid digit, captivating the eyes with its dynamic display.
Precision Timekeeping: NTP and RTCZero
Accuracy is paramount in a clock. Doug harnessed the power of the network time protocol (NTP) and RTCZero library to ensure the clock’s timekeeping remained spot-on. NTP synchronizes the clock with atomic time servers over the internet, while RTCZero maintains accurate time even during power outages, ensuring the clock never loses track of time.
A Case of Elegance and Functionality
Encasing the clock was a custom-designed masterpiece that complemented the Nixie tubes’ retro charm. The enclosure not only protected the delicate components but also added a touch of sophistication to the overall design.
Future Enhancements: A Journey of Innovation
Doug’s creation is a testament to his ingenuity and passion for electronics. While the clock stands as a remarkable achievement, he envisions future enhancements that will elevate it to even greater heights. Additional features, such as alarm functionality and temperature display, are on the horizon, promising to transform this timepiece into a versatile companion.
Bonus: A Timeless Inspiration
Nixie tube clocks, with their warm glow and nostalgic appeal, have captured the imagination of enthusiasts worldwide. Their unique blend of vintage charm and modern technology has breathed new life into an era long gone. As Doug’s Nixie tube clock ticks away, it serves as a reminder that time is a precious gift, and every moment should be cherished.
The clock stands as a testament to the enduring allure of Nixie tubes and the boundless creativity of those who dare to dream of blending the past with the present. In the realm of electronics, innovation knows no bounds, and Doug’s Nixie tube clock is a shining example of this boundless potential.
