North Star is a weather - proof jacket integrated with a light emitting badge for nocturnal guidance intended for hikers and travellers in unfamiliar areas. As the wearer faces north the badge grows brighter, turning south dims the light gradually until it turns off completely when facing directly south. This simple dimming feature allows the user to maintain a constant heading by establishing the associated brightness. As a bonus the light emitted from the product helps the wearer see their way and also be seen by others in the dark.
By utilizing an electronic magnetometer and a set of twelve LED’s connected to an arduino lilypad microcontroller, the navigational lighting maintains high accuracy for the user. One AAA size and one standard 9volt battery are the power sources. The components are housed in flexible waterproof foam padding with thin black ABS plastic edge support to shield the direct light of the LED’s. The exterior of the assembly references the main zipper and pocket fold lines of the jacket: it is sewn into it to achieve full integration and durability. When batteries need to be changed the badge can be opened up with access to all components including the arduino microcontroller for recalibration of the compass if necessary.
