I’m building a discreet, necklace-style safety device that can be worn every day but instantly turns into a lifeline. With one press of its panic button it must both text an alert and place an automated call to pre-saved contacts, while an optional GPS module streams real-time location to a paired mobile app. I already have the concept sketches and a rough feature map; what I need now is an engineer or small team who can take this from idea to working prototype. Core requirements • Necklace form factor, lightweight and comfortable for continuous wear. • Dual-action panic button: simultaneous SMS/notification and voice call triggered through mini button • Plug-and-play GPS add-on that activates when pressing button and send live location to the parents • Low-power design: rechargeable battery targeting at least 72 h standby with BLE advertising • Simple companion app (iOS or Android first is fine) to receive alerts, show live map, and manage contact numbers. I’m open to the stack you prefer—Arduino, ESP32, Nordic nRF, custom PCB—so long as the final prototype is compact, stable and manufacturable. 3D printing for the shell is acceptable during this phase; final enclosure aesthetics can follow once the electronics prove out.

I can help take your necklace-style safety device from concept to a working, compact, and manufacturable prototype. I am an Electrical & Electronics Engineer with experience in low-power wearable and IoT system design, including microcontroller-based products, wireless communication, power management, and custom PCB development. I regularly work from early concept and feature definition through prototyping and hardware bring-up. For your project, I can deliver: • Compact electronics architecture suitable for a lightweight necklace form factor • Dual-action panic button logic triggering SMS/notification and automated voice call • Optional plug-and-play GPS module that activates on button press and streams live location • Low-power system design targeting ≥72 hours standby with BLE advertising • Custom PCB designed for stability, battery efficiency, and future manufacturability • Prototype-ready hardware suitable for 3D-printed enclosures I am flexible on the technology stack and can recommend the most suitable option (ESP32, Nordic nRF, or similar) based on size, power consumption, and reliability. I also design with enclosure constraints in mind to ensure the electronics fit comfortably in wearable products. My goal is to deliver a clean, functional prototype that proves the electronics and power performance before final enclosure aesthetics and mass-production refinements

Hello, I can take your necklace safety device from sketches to a stable, manufacturable prototype. I build low-power wearable/IoT hardware and can cover the full path: architecture, compact PCB, firmware, and a simple companion app. For the panic workflow, I’ll implement a one-press trigger that sends alerts (SMS/notifications) and initiates an automated call to saved contacts. For GPS, I can design a plug-in add-on or integrated module that wakes only during an emergency and streams live location to the parent/app to conserve power. The electronics will be optimized for a lightweight necklace form factor with a rechargeable battery target of ~72h standby while BLE advertising. Suggested approach: a low-power BLE MCU (Nordic nRF or ESP32) paired with a cellular module for reliable SMS/call, plus optional GPS activated on demand. We’ll prototype the enclosure via 3D printing while validating electronics, then refine aesthetics after the system proves out. Deliverables: working prototype hardware, firmware, basic app (Android or iOS first), and manufacturing-ready files/documentation for the next iteration. If you share your sketches, size constraints, and preferred contact flow (who gets SMS/calls first), I can propose a clear architecture and milestone plan. Best regards, -Srijan
