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. Implement Static Wear-Leveling and Data Scrubbing (auto-repairing bit-flips). Ensure the file system is exFAT for long-term cross-platform compatibility. Prototyping & Potting: Assemble one working unit. Finalize the project by Vacuum Potting the assembly in Alumina-filled epoxy resin to create a solid, airtight block.

Hi there, I’ve carefully read your project description and I fully understand the scope: designing a long-life, high-reliability archival storage device with redundant memory, automotive-grade components, bare-metal firmware, and sealed final assembly. This fits my skillset very well. With my background in mechatronics and embedded systems, I have strong experience in PCB design, reliable embedded architectures, low-level firmware (including USB interfaces), and designing systems with long-term stability and fault tolerance in mind. I can help you design the hardware (AEC-Q100 MCU selection, dual eMMC integration, 4-layer PCB with proper layout and component choices), and develop clean bare-metal firmware including USB MSC, mirroring logic, and data integrity mechanisms. I will focus on simplicity, robustness, and long-term reliability as required for a “set it and forget it” system. Given my experience, I’m confident I can deliver this efficiently and professionally. Just send me a message and we can get started right away. Best regards, Samuel Tshibangu

Hello, This is a highly interesting and advanced embedded systems project. I am an Electronics Engineer and founder of AXQUBIT TECHNOLOGIES, with experience in PCB design, embedded systems, and hardware development. I have worked on microcontroller-based systems and reliable electronics design for real-world applications. For your "Digital Fossil" concept, I can assist in designing the core hardware architecture and embedded system foundation, including: • Selection and integration of suitable MCU and memory interfaces • PCB design (multi-layer, reliability-focused layout) • Embedded firmware structure for data handling and USB communication • Basic mirroring logic framework and system architecture • Component selection focused on durability and stability For highly specialized aspects such as long-term reliability validation, advanced wear-leveling algorithms, and industrial certification, I can collaborate or provide structured design guidance. I focus on practical, scalable, and well-documented solutions. I would be happy to discuss and define a clear development scope for this project. Thank you.
