A vibrator helped me debug a motorcycle brake light system
A tale of debugging hardware with unconventional methods. How I perfected the firmware of BrakeBright (a motorcycle safety device) using a vibrator.
That’s exactly why BrakeBright has a built-in USB port, to deliver firmware updates, new features, and performance improvements to every rider, for free. That trip helped resurface a specific edge case I’d seen before: at constant high speeds, the brake light would occasionally flicker briefly, even without any real slowing down. And here’s where it gets smart: if the light turns on and shuts off in under a second, the system assumes it just saw a false positive as a real decelerating or braking event would last much longer than a second.
