My desktop’s hard drive suddenly vanished from both the BIOS and the operating system. All cables and power leads appear firmly seated, yet the drive will not spin up or register on any SATA port I try. I need a skilled hardware repair-focused technician to diagnose the root cause and bring the drive back to a state where it is reliably detected again. The job is strictly hardware-level: testing the drive on proper benches, checking the PCB and controller, inspecting the power delivery, replacing or repairing any failed components, and verifying the unit in a working test rig. If a donor board or firmware flash is required, please let me know beforehand so I can approve sourcing. Deliverables • A repaired hard drive that mounts consistently on a standard SATA interface &bu...

I have a custom board built around the STM32G031 and I want a clean, production-ready firmware project created in C with STM32CubeIDE. Your first task is to bring the microcontroller to life: set up the system clock, configure the required GPIO pins, verify the build, and program the device. Here is the scope I need covered: • Create a CubeIDE project that targets STM32G031, using either HAL or direct LL drivers where it makes sense. • Configure clock tree (HSE, HSI or internal PLL as required) so the MCU runs at the specified operating frequency. • Initialise all GPIOs I mark on the schematic; direction, speed and pull settings must match the hardware design. • Build, generate the .hex/.bin files and flash them onto the board through ST-Link over SWD. • ...

I need an embedded-software specialist who can take my collection of Wi-Fi and LoRaWAN gateways and assorted sensors and knit them into a single, production-ready IoT platform. The job covers the full stack from firmware that runs on the edge devices through to the application layer that users will see. Core capabilities the platform must deliver: • Data collection from every gateway and sensor • Robust device management (on-boarding, remote configuration, OTA updates) • Built-in analytics so I can visualise trends and run simple rules without exporting data elsewhere You’ll be free to recommend languages, embedded RTOS options, and cloud back-ends, provided they reliably handle both Wi-Fi and LoRaWAN traffic and scale cleanly as more hardware is added. Deliverables...

Hello Yernaidu, Thank you for your proposal. I'm interested in working with you on my Big Hero 6-inspired modular micro-robot project.

Two independently controlled robotic arms with adjustable angles and a target of 360° rotation. 4. Forward and backward movement mechanism. 5. Robot-to-robot docking and separation mechanisms. 6. Relative position detection between robots. 7. Bluetooth communication and microcontroller firmware. 8. Python-based PC software...

1. Project Overview & Architecture The goal of this project is to design a set of modular, decentralized expansion PCB boards for grow tent automation. Instead of a rigid central mainboard, each expansion board functions as an independent node powered by a localized ESP32-C3 Supermini module, communicating via Wi-Fi/MQTT through ESPHome into Home Assistant. To reduce clutter and eliminate the need for multiple external power supplies, all boards will share a common power distribution concept: 12V DC Input (via standard 5.5x2.5mm barrel jacks or terminal blocks) with onboard step-down regulation (e.g., Buck converters) to supply 5V and 3.3V where needed, allowing a single 12V barrel power supply to be daisy-chained across boards. 2. General Requirements for All Boards Microcontroller: ...

I am looking for an experienced power electronics engineer or engineering team to design a residential-scale hybrid solar inverter for commercial production. The project involves developing a single-phase, 230 V AC, 50 Hz pure sine-wave hybrid inverter that integrates rooftop solar panels, a lithium battery bank and the utility grid. The design should prioritise high efficiency, reliability, safety and ease of manufacturing. I prefer an engineer with previous experience designing working solar inverters, grid-connected converters, MPPT controllers and bidirectional battery systems. An existing, validated reference design that can be licensed or transferred is preferred. 1. Target Specifications Rated power: 1–5 kW continuous AC output: 230 V RMS, single phase, 50 Hz Output wave...

I need a skilled PCB designer to convert my existing through-hole PCB, designed in Fritzing, into an SMD PCB for production using KiCad. The design works great, but I need it to be SMD. Requirements: - Convert the following components from through-hole to SMD: - ICs (including ESP32, A7670G modules, and charge controller) - Use of standard footprints for all SMD components. Ideal Skills and Experience: - Proficiency in KiCad - Experience with SMD PCB design and layout - Familiarity with the specified components (ESP32, A7670G, charge controllers) - Attention to detail and accuracy in design Please provide samples of previous SMD PCB designs.

My BMZ Power2Go Work portable power station—just 14 months in service—shut down abruptly while delivering a steady 1 600 W load (it is rated for 2 500 W continuous, 3 600 W peak). Since that moment it refuses to charge or power on; every status LED remains dark. I need a battery technician who can carry out a full diagnostic and bring the unit back to life. That means opening the enclosure, verifying cell health, checking the BMS, charger circuitry, DC-AC inverter stage, and any internal fuses or relays. Once the fault is identified I want the defective components replaced or rebuilt so the pack can once again charge fully and supply its original output ratings without thermal or voltage irregularities. Deliverables: • Detailed test report outlining root cause, measureme...

iPhone Battery Management System inside-out and can work across software, hardware, and firmware layers to alter the way battery health data is reported. The goal is to change the internal metrics that feed the Health section in iOS so the device shows revised capacity, cycle count, and related statistics without triggering errors or safety lockouts. Can you make a Custom device that can be use on a factory level,hat helpful to change battery health and cycle by just connecting the battery BMS only. Scope • Reverse-engineer or otherwise access the BMS firmware and its data pathways. • Modify the algorithms or calibration tables that calculate battery health. • Validate the change on real hardware so the phone operates normally under charge, discharge, and idle state...

Hello PCBWay, I need you to design and supply a fully assembled, programmable PCB for a battery-powered motion recorder. I do not have a schematic and cannot solder components myself. Please check whether an existing design could be adapted to reduce the cost. **Shape and size** - Rectangular PCB with rounded corners. - Standard credit-card dimensions: 85.60 × 53.98 mm. - Keep the PCB and components as thin as practical. - A separate flat LiPo battery will sit behind the PCB. Please keep the battery area clear of tall components. **Hardware** - A low-cost, low-power microcontroller that I can program myself. - An onboard 3-axis accelerometer and 3-axis gyroscope. - Two assembled push buttons: 1. Power on/off. 2. Start recording; press the same button again to stop and save. - One pro...

I need a production-ready PCB for an industrial ranging device that will be integrated into larger automation machinery on our factory floor. The board has to combine three core capabilities: robust signal processing of the sensor data, reliable high-power outputs to drive downstream actuators, and on-board wireless communication for status reporting and firmware updates. The footprint must stay within 80 mm × 60 mm, operate from a 24 V DC rail, and meet industrial EMC/EMI standards (EN 61000 family). A multilayer stack-up with controlled impedance traces for the RF section is expected, along with generous creepage/clearance on all high-current paths. Deliverables • Schematic (Altium or KiCad) • Fully routed Gerber/ODB++ files ready for fabrication • Annotated ...

I need a complete electrical design for a true-online 600 W UPS that will operate in a home environment.
