Senior Hardware Engineer: Turnkey ESP32-S3 PCB Design (18x35mm) Project Overview I am seeking a senior hardware engineer to design a professional, 4-layer, double-sided PCB for a high-performance travel IoT device. This device acts as an IR blaster, local AI audio monitor (for volume/occupancy), and environmental sensor. Completion Criteria: This is a turnkey electrical project. The project is considered complete only after I have physically tested the manufactured boards and validated that all sensors, voice features, and power circuits work as specified. Core Hardware Specifications MCU: ESP32-S3-WROOM-1U-N16R8 (16MB Flash / 8MB PSRAM). Antenna: connector for external flex-film antenna. Dimensions: Strict 18mm x 35mm footprint. Storage: Molex 104031-0811 MicroSD socket (Push-pull...

I have fifteen disassembled original first generation "cigalike" e-cigarettes waiting for fresh new cells. The spent batteries still have to come out; I’ll supply the brand-new replacements along with step-by-step instructions I’ve written from my own repair notes. Once each cell is tinned and soldered, the board and wiring need to slide back into the original metal tubes that I will ship with the lot. After reassembly I need every unit verified for both firing (making sure the LED end eliminates, and it produces vapor,) and charging. A simple functional puff/hit-to-vape check is the first pass, then confirmation that each battery takes and holds a charge using a charging USB that I will provide. If anything reads off, I’d like a quick note so we can decide whe...

I need a complete hardware-to-firmware solution for a low-power, standalone temperature and humidity monitor that relies on 4G/LTE rather than Wi-Fi. The core will be an ESP32 driving a SIM7600G module, paired with a DHT22 sensor. Collected readings must be published over MQTT to my Supabase/PostgreSQL back-end. The device will sleep most of the time, wake on schedule, take a reading, push it securely, then drop back into deep sleep. It also has to recognise a lost cellular link, attempt reconnection gracefully, and log any failures for later review. Power comes from a Li-po pack, topped up through a USB-C port, so the design needs an efficient charging and protection stage. Please deliver: • Complete, readable schematic (PDF + source) • Production-ready PCB layout with G...

I am looking for someone who specializes in repairing automotive modules such as ABS, Power steering, ECU modules. I am looking for someone who can be my go-to person when it comes to technical assistance and support as I am a beginner. Would like someone to recreate the board in software to become easily readable and easy to trace faults. Need someone who has experience in bench testing these modules so that when my customers receive them they will be working.

I’m looking for a skilled hardware-and-firmware engineer to create a SMART Power Distribution Unit that I can move quickly into production. The unit must include: • Remote monitoring of every outlet • Per-outlet and aggregate energy metering • Built-in surge protection that meets standard safety ratings I’d like the communication layer to run over SNMP, so please plan your microcontroller, Ethernet stack, and MIB files around that protocol. If you normally add Modbus or HTTP support, feel free to flag that as an optional extra, but SNMP is essential. 1 inlet 220V 20A, 8 outlet 220V 5A. It case refer 1U measure. Mechanical parts are manufactured by ourside. Core deliverables I expect: 1. Complete electrical schematic and PCB layout (Altium, KiCad, or s...

precision Track Glucose Monitoring System Full Description The Precision Track Glucose Monitoring System is a wearable, continuous glucose monitoring (CGM) prototype designed to deliver accurate, real-time glucose data for individuals managing diabetes and related metabolic conditions. The system uses an electrochemical biosensor to measure glucose levels in interstitial fluid and converts this data into actionable insights through integrated microelectronics and wireless communication. At the core of the device is a high-reliability printed circuit board (PCB) platform, engineered to support precise signal processing, low power consumption, and compact integration. This allows the device to maintain clinical-level accuracy while remaining lightweight and comfortable for everyday wear. T...

I’m putting together a small outdoor rack and need an electronic sensing solution that can tell me, in real time, whether something has been placed on—or removed from—each shelf. Cameras are off-limits, so I’m looking for a clean sensor-based approach that works equally well with mixed materials such as metal, plastic, or any everyday composite an item might be made from. Because the rack will sit outside, the hardware must shrug off normal weather exposure—sun, light rain, the usual seasonal swings—but it doesn’t have to survive arctic freezes or tropical monsoons. A compact, low-power design is preferred, and I’m open to ultrasonic, IR, capacitive, load-cell, or any other sensor technology you feel is best suited to the job, provided it st...

Preciso desenvolver um Módulo de Distribuição de Energia com 18 saídas, inspirado nos PDM15 que já uso como referência interna. O objetivo é assegurar três funcionalidades cruciais desde a primeira versão: proteção contra sobrecarga em cada canal, monitoramento remoto em tempo real e controle individual de todas as saídas. Quero comandar e visualizar tudo numa interface web amigável, acessível tanto em desktops quanto em smartphones; portanto, a parte de firmware e a camada de software devem expor servidores HTTP-REST ou WebSocket que facilitem integrações futuras. Ainda não defini requisitos de compatibilidade com sistemas externos, então o código e o hardwar...
