Lecture
This lecture presents a two-part system designed by Group 5, Elodie, Gonzalo, and Guillaume, to enhance needle safety in the Bernina sewing machine. The system includes a needle position indicator with a laser pointer and a finger proximity detection system that provides warnings and can stop the machine in emergency situations. The group explains the design process, from 3D printing relevant parts to connecting and coding electronics for the prototype. They also propose a solution to stop the needle in case of danger, outlining the potential implementation of an SPDT relay. The lecture showcases the prototype in action, demonstrating the functionality of the laser, finger detection, and the proposed needle-stopping mechanism.
