911 Cross

thingiverse

This project is designed specifically for the Autodesk Fusion 360 Challenge (prompt #1), a wearable device aimed at keeping individuals safe during their commute. The primary objective was to create not only a functional design but also a full-size, 3D-printed model to test its effectiveness in real-world scenarios. The wearable device takes the form of a rosary, featuring a single button that can be pressed to send a signal to police or other contacts. The cross is connected to a smartphone via Bluetooth technology. The button itself contains a multicolor LED light that provides information on the device's state, such as low battery (red), charging in progress (blinking green), and full charge (green). Additionally, a vibromotor can be used to alert users of important events. Charging is facilitated through a small wireless dock station, which utilizes a coil in the cross to transmit energy when it is placed on the base. This design ensures that the rosary remains compact and unobtrusive. The device's innocent appearance and affordable price point prevent any potential for greed or aggression. A magnet located at the back of the cross enables users to attach the rosary to a fridge, transforming it into a stationary emergency button. It can also be placed on a rearview mirror in a vehicle or anywhere nearby. The beads feature threaded shafts that allow users to adjust the chain length, making it suitable for wear as a necklace or belt. The entire design was created using Autodesk Fusion 360.
