Cześć, szukam osoby do stworzenia prostego prototypu urządzenia safety (IoT) dla pracowników pracujących na wysokości (np. turbiny wiatrowe). Chodzi o szybkie MVP, nie finalny produkt. Zakres projektu: 1. Hardware (ESP32): - odczyt danych z akcelerometru (wykrywanie ruchu / brak ruchu) - integracja GPS (NEO-6M lub podobny) - obsługa przycisku SOS - wysyłanie danych przez Bluetooth lub WiFi 2. Logika: - wykrycie braku ruchu przez określony czas (np. 2–3 min) - wysłanie alertu (status + lokalizacja) 3. Prosty backend / komunikacja: - może być Firebase lub coś podobnego 4. (opcjonalnie) prosta aplikacja / dashboard: - mapa (lokalizacja) - status: OK / brak ruchu / SOS Cel: Chcę mieć działający prototyp do testów z firmą (demo), nie potrzebuję jeszcze perfekcyjneg...

I need a complete electronic design for a next-generation health-monitoring smartwatch whose signature element is a high-resolution micro camera mounted flush to the wrist side of the case. That camera will analyse the wearer’s skin to extract deeper, image-based health insights beyond the usual heart-rate and SpO₂ readings. I am open to your proposals on exactly which metrics image processing can reveal, provided they are scientifically sound and can be handled by an embedded processor in real time. Core hardware requirements • High-resolution skin-facing camera, paired with a wearable-class microprocessor powerful enough to process or compress the image stream on-device. • Minimum 16 GB on-board storage for captured data. • Bluetooth for data sync, a vibrant T...

I need a production-ready printed circuit board for a compact consumer-electronics tracker. The board has to combine Bluetooth connectivity for smartphone pairing, GNSS positioning for global location data, a LoRa module for long-range updates, and a 3-axis motion sensor to wake the unit only when it moves. Everything will run from a single rechargeable battery, so careful power budgeting and a low-power microcontroller are essential. Form-factor will be small enough to slip into a key-tag style enclosure, so component height and antenna placement must be considered from the start. I’m flexible on the exact silicon—Nordic, Espressif, STM, Semtech, etc.—as long as you can justify part choice against current draw, cost and global availability. Please take the design from ...

I'm looking for a skilled developer to create a unique vocal training device that incorporates wearable technology. This device will be designed to fit around the neck, utilizing sensors and Bluetooth tech. Key functionalities: - Real-time feedback on vocal performance - Visual feedback on a connected app Ideal Skills and Experience: - Expertise in wearable technology development - Proficiency in sensor integration and Bluetooth connectivity - Experience in building user-friendly mobile applications for real-time data display - Background in audio processing or vocal training technology is a plus Please provide samples of similar work and a rough timeline for project completion.
