Project Overview: I am looking for an expert Embedded Systems Engineer to design and build a single, high-reliability storage device meant to last 50 years without repair or maintenance. This is a "set it and forget it" archival project. Scope of Work: Hardware Design: Select an Automotive-Grade MCU (AEC-Q100, e.g., NXP S32K or ST SPC5 series). Implement Dual-Redundant 256GB Industrial pSLC eMMC chips (mirrored for 128GB usable space). Design a 4-layer PCB with ENIG (Gold) finish. Use Ceramic Capacitors (MLCC) only; strictly avoid electrolytic/tantalum. Hard-wire a gold-plated USB-C pigtail directly to the PCB. Firmware Development (Bare Metal): Implement USB Mass Storage Class (MSC) for driverless PC compatibility. Develop RAID-1 Mirroring logic between the two eMMC chips. Imple...

Hi there amazing freelancers, I have a relatively simple wiring diagram that I need converted to a KiCad file to send out for 3rd party fabrication. Please see attached image and diagram.

I am developing a new consumer hardware product that blends traditional cultural design elements with modern technology and usability. The product will be a small, handheld electronic device with a strong focus on: Industrial design (premium look & feel) User interaction experience Compact and ergonomic form factor Heat-related internal functionality (low-to-moderate heat system) Replaceable/refillable component system ⚠️ Important: Full concept details will only be shared after signing an NDA.

My motor-driven inspection robot already works, but its electronics and code now need a serious upgrade. The mobile unit talks to a control box through a 100-metre twisted-pair cable while a vision camera streams live video, so every watt saved and every microsecond trimmed matters. Phase 1 – Mobile Unit I want the existing PCB completely re-laid to improve thermal behaviour, noise immunity and overall robustness. You will analyse the current board, then redesign it for cleaner power distribution, better signal integrity and easier field service. Schematics, PCB files (Altium or KiCad preferred), BOM and production-ready Gerbers are expected. Phase 2 – Control Box Inside the controller several separate boards handle power, comms and motor control. I need these consolidate...

I’m developing a commercial product that relies on a set of interactive elements—speakers, sensors, and LED displays—and I need clean, production-ready schematic diagrams that tie them all together. The core of the job is translating my functional requirements into well-documented circuitry that in-house team can follow without second-guessing pinouts, signal paths or power budgets. This is an interactive piano that plays audio files. You’re free to work in whichever design environment you’re most comfortable with—Altium, KiCad, Eagle, OrCAD, or any other professional tool—as long as the resulting files can be shared in their native format plus PDFs for quick reference. What I expect from you: • A complete, logically organised schematic sho...

I’m upgrading an existing research-grade air-monitoring prototype and need fresh expertise on both its brains and its senses. Right now the unit records basic gas, temperature and humidity data, but sensor accuracy drifts and the firmware is held together by quick fixes. Hardware goals My first priority is the sensor chain. I need informed recommendations on higher-precision sensors and transducers, signal-conditioning circuitry, and a calibration strategy that produces traceable, publication-ready data. If swapping microcontrollers or revising the PCB layout will improve stability, please outline the change. Software goals The current code captures data but offers little filtering, self-diagnostics or scalability. I want clean, well-documented firmware (or a lightweight desk...

I am building a set of compact, plug-and-play factory modules—currently a welder, a mixer, and an extruder—driven by a single Raspberry Pi RP2040 brain. For each module I need both the electronic heart and the mechanical body designed in tandem, so the PCB layout, electrical schematic, 3D enclosure, and any mounting or cooling features all fit together flawlessly. Your task covers everything from component selection and trace routing through to printable CAD models, with the RP2040’s pin-mapping and firmware headers fully accommodated. If you can suggest clever inter-module connectors, safety interlocks, or space-saving enclosure tricks, even better. Deliverables • Complete electrical schematics (KiCad or Altium) for welder, mixer, and extruder • Production...

I have a V2 Nintendo Switch tablet and I’m ready to take it beyond stock capabilities. Specifically, I need a hardware-level installation of a Picofly chip so the console can support extra accessories and any future custom expansions I may add. Here’s what matters most to me: • Clean, professional solder work with minimal cosmetic impact • Firmware-safe routing so all standard functions (Joy-Cons, Wi-Fi, dock) remain intact • A short demonstration video or photos showing the chip working on my unit before return shipping You tell me the exact turnaround time, the shipping steps you prefer, and any warranty you put on your workmanship—then I’ll get the console in the mail to you right away.
