Why People Can Always Tell When AI Wrote Your Text
Young adults are letting ChatGPT draft their texts and hard conversations. Here's why it's obvious and what actually works instead.
I'm seeking an experienced embedded electronics engineer to help develop a prototype for a wearable medical device or biosensor. The primary function of the device is yet to be determined, but it could be related to monitoring vital signs, tracking physical activity, or detecting specific biomarkers. Key requirements: - Expertise in firmware programming is essential. - Experience with wearable medical devices or biosensors is highly desirable. - Skills in PCB design, sensor integration, and prototype development would be a plus. The ideal candidate should have a strong background in embedded systems and a proven track record in developing prototypes for medical or health-related devices.
**Project Title:** Industrial Vibration Monitoring PCB Design (Schematic + 4-Layer Layout) – JLCPCB Compatible **Project Description:** We need a complete PCB design for an industrial IoT vibration sensor used in predictive maintenance of rotating machinery (motors, pumps, fans, gearboxes). **Important:** All components must be available on **JLCPCB / LCSC**. Prefer parts that are in stock or have good availability. Avoid parts that require consignment unless absolutely necessary. **Scope of Work:** - Full schematic design - 4-layer PCB layout - Component placement, routing, and silkscreen - BOM with **JLCPCB/LCSC part numbers** - Design notes (power sequencing, sensor power-down, RF layout) **Key Requirements:** **Core Components (use JLCPCB-available equivalents or exact pa...
Tôi cần xây dựng một hệ thống giám sát dựa trên Arduino để theo dõi nhiệt độ, độ ẩm, cường độ ánh sáng và trạng thái mất điện. Khi bất kỳ thông số nào vượt ngưỡng hoặc khi mất nguồn, hệ thống phải gửi cảnh báo theo thời gian thực qua SMS; nếu anh/chị có thể bổ sung thêm thông báo trên ứng dụng di động thì càng tốt. Yêu cầu chính • Mạch Arduino hoàn chỉnh kèm sơ đồ nối dây, danh sách linh kiện và mã nguồn. • Cấu hình ngưỡng linh hoạt cho từng cảm biến, lưu trong mã hoặc qua giao diện cấu hình đơn giản. • Gửi SMS tự động (ưu tiên dùng SIM800L/SIM900 hoặ...
Necesito un esquema y PCB completos en EasyEDA que integren los siguientes módulos y funciones: • Slot compatible para los módulos Lilygo SIM7000G y A7670SA. • Dos INA219 independientes: uno para medir la batería y otro para el panel solar. • Regulador de carga solar MPPT CN3791 para paneles de 6 V (entrada dedicada). • Sensor ToF VL53L1X integrado en la placa más un conector para una versión externa. • Cargador de batería basado en TP4056 con sus protecciones. • Conector para batería 18650 y, adicionalmente, para batería Fanso. • Encendido controlado mediante reed switch y MOSFET. • Elevador MT3608 fijado a 5 V. Dimensiones deseadas de la tarjeta: 110,54 mm × 32,89 mm (pue...
I’m working with Avishkaar AMS and need a skilled block-coder to help me push the platform’s limits. The goal is pure experimentation and testing, so we can tinker, iterate, and learn fast without being tied to a fixed lesson plan. The blocks you create will drive a small robot that also hosts a sensor stack. I want to see it: • move precisely and navigate around a mapped or unknown space, • sense and avoid obstacles in real time, and • log key sensor readings so I can later analyse the data. All code must be built only with the official Avishkaar AMS block palette—no external scripts or text-based hacks—so everything runs natively on the board. Comment your blocks clearly, keep each routine modular, and share the final program file along with a...
