Current Status

• POC #4 on two different sized prototype PCB = ✅

Up Next

• Pick a PCB size (3x7cm vs 2x8cm) and create a case;

Introduction

• My daughter uses a wheelchair, it has an anti-tilt protection usually folded out (it's an arm that stretches beyond the wheel and keeps the wheelchair from tilting back);
• We need to help her up and down stairs and in order to be able to roll over the steps, the anti-tilt protection needs to be folded in;
• If the protection is left folded in, there is a high chance of her making the chair tilt back and high risk of a serious injury to her head;
• We need an alerting/notification mechanism to let the user and the helping hand know that the protection is not in its safe position;
• I am currently calling it: Wheelchair safety buzzer

Rough Idea

• The current mechanism is made of a spring-loaded tube inside another and locking at 180 degrees rotations;
• Attach a sensor to the top one and the magnet to the bottom one;
• Whenever they are not in close proximity, there is a constant notification until the protection is folded into its safe position;
• Side note: Eventually consider adaptability for other wheelchair models;
