多年远离摩托车后,重新燃起的热情促使我开发了BrakeBright,一款旨在增强摩托车安全的智能刹车灯系统。一位CBT教练关于在发动机制动时使用刹车的建议启发了我,我意识到仅仅依靠习惯来应对如此重要的安全措施是多么不足。现有的解决方案都存在缺陷,这促使我创造了一种在发动机制动时自动激活刹车灯,并根据制动强度进行比例闪烁的装置。 BrakeBright的开发涉及无数个小时对原型进行改进,这得益于朋友摩托车的帮助,期间克服了诸如传感器精度和振动干扰等挑战。广泛的测试,包括在苏格兰NC500公路上的严格测试,确保了其可靠性。最终产品内置加速度计,具有防水和防振功能,并提供USB接口,方便用户更新固件和自定义设置。 第一批产品到货的那一刻,我感到无比的欣慰。BrakeBright旨在使先进的安全功能民主化,让所有骑手都能通过简单易安装的改装来获得这些功能。我的旅程证明了热情和信念可以将想法转化为现实。我欢迎各位的反馈和支持,因为我将继续为所有人的摩托车安全改进做出努力。

Hacker News 上的一个帖子讨论了一个项目,该项目旨在通过基于加速度计的刹车灯来提高摩托车安全性,即使没有激活刹车拉杆,该刹车灯也能在减速时亮起。评论者们就其有效性、必要性和潜在的故障点进行了辩论。 一些用户强调,由于大型车辆和分心驾驶,摩托车手的危险性越来越高。头盔刹车灯、反光胶带和摄像头被建议作为额外的安全措施。不断上升的死亡率和有争议的起因令人担忧,尽管受伤率下降为设备和方法的有效性带来了希望。 讨论还涉及摩托车上的 ABS 制动系统,强调了前制动器在保持稳定性方面的重要性。他们进一步讨论了在紧急制动情况下闪烁刹车灯的有效性和合法性。评论者强调用户应始终采取防御姿态,不要依赖他人看到自己。这包括公开携带武器,尽管许多用户对此表示反对。还有一些关于摩托车灯最佳放置位置的讨论。 一些人表达了对潜在的误触发、USB 端口可靠性和设备故障时的故障保护机制的担忧。

It began with a spark—a dormant passion reignited after many years away from motorcycling. Life had steered me in different directions, away from the saddle, but something deep inside pulled me back to the thrill and freedom that only riding offers.

Returning to motorcycling after such an extended hiatus was daunting yet exhilarating. I vividly recall my first CBT session: the nerves, the good-natured laughter at my clumsy mistakes, and the sheer joy when everything finally clicked into place. It was during this session that a critical moment of inspiration occurred. My instructor casually suggested lightly applying the brakes during engine braking to alert drivers behind that I was slowing down. Given motorcycles’ inherent lightweight design and strong engine braking, the risk of being rear-ended was significant.

It struck me profoundly how something so vital could be left to mere habit—this realization triggered my engineering instincts. Relying solely on human memory and habitual action seemed inadequate and unreliable. I wondered: “Could technology automate this essential safety process?” Thus, BrakeBright was conceived—a smart brake-light system specifically tailored for motorcycles. BrakeBright intelligently detects when the motorcycle slows due to engine braking, activating the brake lights even before the rider manually applies the brakes. Moreover, during intense braking scenarios, it flashes proportionately to the braking intensity.

Curious to see what was already available, I purchased one of the few similar products on the market. To my surprise, it relied solely on a basic tilt switch, rattling excessively during rides despite claims of “advanced technology.” The device was not only ineffective but also potentially hazardous. Drivers instinctively focus on brake lights; unless the brake light itself clearly indicates deceleration, most would fail to notice.

Interestingly, adaptive brake light technology already exists in high-end vehicles. BMW’s dynamic brake light, for example, flashes during emergency braking to alert trailing drivers, greatly enhancing road safety. Similarly, KTM motorcycles incorporate an Adaptive Brake Light system for better visibility during sudden deceleration. However, such advanced safety features have traditionally been reserved for premium models. My vision for BrakeBright was to democratize this essential safety feature, making it accessible to every rider through a simple, straightforward modification. Installation requires no special tools—using posi-tap connectors, BrakeBright easily integrates with your motorcycle’s existing wiring in just minutes.

Developing BrakeBright involved starting with a simple motion sensor and microcontroller unit (MCU) on a breadboard. Countless hours went into refining the device—tweaking, programming, and improving—long before I even had my own motorcycle license. As the idea evolved, I designed the initial printed circuit board (PCB) prototype, carefully hand-soldering tiny surface-mount components late into the night.

Testing presented another unique challenge—I initially didn’t own a motorcycle. My friend Johny generously volunteered his bike for field testing. I sent each prototype iteration to him, and he diligently provided feedback that guided continuous improvements. This iterative process spanned several months, steadily bringing BrakeBright closer to perfection.

By the third PCB version, I had my motorcycle and could directly test and refine the system. Challenges arose frequently: vibration jitter interfering with sensor accuracy, synchronization issues between sampling rates and engine RPM, and false positives during long rides. To visually verify BrakeBright’s actions, I installed an LED at the front of my motorcycle, enabling real-time monitoring. This hands-on method significantly improved reliability, particularly the flashing-on-hard-braking feature. BrakeBright employs a sensitive accelerometer to detect velocity changes accurately, determining whether the motorcycle is slowing due to engine braking or active rider input. It’s also engineered to be fully waterproof and vibration-resistant, ensuring dependable performance under any riding conditions.

Thousands of miles of rigorous testing followed, notably including Scotland’s iconic NC500 route alongside Johny—misty mornings, sweeping highland bends, and dramatic descents providing the ideal proving grounds. One vivid memory stands out: braking sharply on a tight, downhill hairpin near Applecross Pass, I observed BrakeBright’s flash sequence activate exactly as intended—clear, swift, and unmistakable. Riders especially appreciated BrakeBright’s flashing feature, noting how it significantly improved rearward visibility during intense braking situations.

Another challenge emerged when the initial BrakeBright unit required specialized equipment for firmware updates. Committed to empowering users, I developed a subsequent version incorporating a USB port. Currently, I’m finalizing user-friendly software utilities, enabling riders to easily update BrakeBright firmware, customize features, and personalize the system to match individual riding styles and preferences.

Months of effort culminated in the thrilling moment the first production batch arrived. I still recall opening the box at my workbench—the scent of fresh solder and cardboard filling the air—and seeing the finished BrakeBright units gleaming. Holding one in my hands, experiencing its meticulous craftsmanship and sleek design realized exactly as envisioned, was profoundly rewarding. I felt immense pride, a hint of nervous excitement, and deep satisfaction.

Yet, this is merely the beginning. The initial shipments and early customers symbolize far more than sales—they validate that risk-taking, passion, and belief can transform ideas into reality. With an open feedback loop and software upgrade tools nearing completion, I’m eager to see riders embrace BrakeBright, making it uniquely theirs.
