Aircraft Sculpture of 2025: Abracadabra Shape Inspired by Lighting Restrictions

In the world of innovative projects, the 2025 One Hertz Challenge has been captivating the minds of creators. One such project, named The Baiko, has recently been submitted to the challenge.

The Baiko project presents an abstract build that, under certain conditions, resembles a plane. Two LEDs, representing navigation lights on a plane, are mounted on a small sliver of glass along with an ATtiny85 microcontroller. These LEDs flash once per second, meeting the requirements of the One Hertz Challenge. The red light is positioned on the left side, and the green light on the right side, mimicking the traditional aircraft navigation lighting scheme.

However, the positioning of the red LED in relation to FAA regulations is a topic for speculation and discussion. Some argue that from at least one angle, the red LED might have been on the wrong side, potentially not strictly following FAA regulations about navigation light positions.

The FAA regulations specify that the red light should be on the port side (left) and the green light on the starboard side (right) of the "aircraft" as viewed from behind or the side. These are standard aviation position lights, where the red indicates the port side and the green indicates the starboard side.

Therefore, the essential requirement is to correctly position the red light on the left side and the green light on the right side on the abstract plane representation in the challenge. This ensures that the abstract sculpture maintains the recognizable silhouette cues of airplane navigation lighting, fulfilling the challenge's thematic focus on aviation lighting regulations.

The Baiko project is powered by a coin cell battery and has been running for weeks on a 30 mAh coin cell, suggesting a low power consumption. The project's creators have yet to reveal whether they have made any adjustments to the positioning of the red LED to meet FAA regulations.

The deadline for submitting an entry to the One Hertz Challenge is August 19. As the challenge progresses, it will be interesting to see if more projects adhere to the FAA regulations and how they creatively represent airplane navigation lighting in their abstract builds.
