Elektronikai tervezés Jobs

I am developing a wearable electronic device for sports such as padel or tennis that allows players to easily record points during a match. The system consists of a small button worn on the player’s shirt that communicates wirelessly with a courtside speaker. When the button is pressed, the system updates the score and announces it audibly. Current Stage: Prototype development. The goal is to design a functional, low-cost, and manufacturable electronic system that can later be scaled to production. System Components: 1. Wearable Button Unit * Small, lightweight device clipped to the player's shirt * Single push button input * Bluetooth Low Energy (BLE) communication * Rechargeable battery (Li-Po) * USB charging circuit * RGB LED status indicator: * Gr...

I need an engineer who knows ETAP inside-out to build and run a full fault-current model of my power system. The single-line diagram is ready; what’s missing is a cleanly-configured ETAP file that captures all protective devices, conductor data, and transformer parameters so I can see worst-case fault duties before equipment is ordered. The task centres on: • Setting up (or sanity-checking) the short-circuit module, clearing any data inconsistencies, and choosing the correct ANSI / IEC calculation options. • Delivering a concise PDF and the native .etap file that lets me trace each bus, breaker, and transformer contribution. I’ll provide the drawings, manufacturer sheets, and any utility data you need. Please highlight any data gaps early, walk me through the mo...

Necesito un diseñador electrónico que me ayude a pasar de idea a archivo Gerber una placa de 15 × 15 cm lista para fabricar en JLCPCB. Componentes que debo integrar: • 1 ESP32 montado tipo “solder-on”. • 4 pantallas LCD conectadas por cable. • 4 relés con su respectivo LED indicador. • 2 módulos de 315 MHz, previstos con conectores tipo header (tal como los quiero montar). • 1 módulo para tarjeta micro SD. Aún no dispongo del esquema eléctrico, así que también requiero apoyo para elaborarlo y validar la asignación de pines, trazos de alimentación y señales. Cuando el circuito esté claro, necesito: 1. Diseño del esquemático completo ...
