Job Title: Experienced Hardware Engineer – Custom Embedded Linux IoT/Controller Hardware (Prototype) We are looking for an experienced Hardware & PCB Engineer to design a prototype expansion module/accessory for an interactive game controller environment. The device will be a high-performance, ultra-low-power embedded board featuring wireless connectivity (Bluetooth & Wi-Fi) and a 6-axis Accelerometer/Gyroscope (IMU) motion-tracking sensor suite. The target architecture is based on an Embedded Linux platform (ARM/SoC/SoM) with a heavy engineering focus on battery power optimization and custom power management circuits. Your main responsibility will be board-level schematic design, multi-layer PCB layout, component selection, and preparing production-ready manufacturing files ...

Request for a Custom Pre-Configured CAN/CAN-FD Gateway for EV BMS Development and Testing I would like to request a quotation for a complete, standalone CAN/CAN-FD gateway system. I am looking for a device that can be connected between the vehicle and the OBD connector using an OBD interposer, and that can operate independently without a PC using pre-loaded configurations. The main purpose of the system is development and testing of battery/BMS CAN communication in electric vehicles. The vehicles I would like to support are: * Tesla Model 3 * Tesla Model Y * Kia e-Niro * Hyundai Kona Electric * Volkswagen ID.3 * Volkswagen ID.4 I will provide the exact model years for each vehicle at the beginning of the project. Required functionality * At least 2 independent CAN/CAN-FD channels *...

I need a compact, high-performance microstrip antenna engineered specifically for satellite communication in the mmWave region. The goal is to move from concept through full-wave simulation to fabrication-ready files while meeting tight performance targets on gain, bandwidth, and axial ratio. Scope of work • Electromagnetic modelling and optimisation in a recognised solver such as HFSS, CST, or similar, covering the exact mmWave band that satellite links typically occupy. • Substrate selection with justifications (εr, loss tangent, availability). • Impedance matching network design to maintain ≤-10 dB return loss across the operating band. • Radiation pattern validation for both boresight gain and sidelobe levels suitable for satellite uplink/downlin...

We are developing a Shabbat-compliant smart alert lamp designed for observant households in Israel. The system connects Tuya-compatible smart lamps/switches with real-time emergency alert data (Pikud HaOref / Red Alert API). During Shabbat, the lamp must visually alert users (via color changes or preset light patterns) without violating Halachic principles (no user intervention, automated triggers, silent visual alerts, and local state memory). היקף עבודה ותחומי אחריות (Key Responsibilities & Scope): Tuya IoT Platform Configuration: Set up the Cloud project on Tuya IoT Developer Platform. Define Product ID (PID) and Data Points (DPs) tailored for custom smart lighting/alert states. Real-time API Integration & Bridge: Build a lightweight, high-availability backend bridge that ...

Potrzebuję funkcjonalnego prototypu niewielkiego systemu, który bezprzewodowo poinformuje o obecności osoby w pomieszczeniu. Co musi zrobić urządzenie • Czujnik ruchu PIR, zasilany wyłącznie baterią, wykrywa obecność. • Wskaźnik LED przy drzwiach – również zasilany z baterii – automatycznie zmienia kolor, gdy czujnik coś wykryje lub gdy pomieszczenie znów jest puste. • Między elementami nie może być żadnego okablowania; komunikacja ma być w pełni bezprzewodowa. Kluczowe wymagania • Bardzo niski pobór energii – zależy mi na długiej pracy na jednym komplecie baterii. • Stabilna, odporna na zakłócenia łączność (BLE, Zigbee, Sub-GHz lub inne rozwiązanie, które zaproponujesz). • Kompaktowe wymi...
