The original schematics and firmware sources for my existing motherboard are no longer available, yet I still need to keep the product alive and solve a series of recurring hardware failures. The immediate objective is to reverse-engineer the board in detail so I have a complete, accurate picture of how every power rail, I/O interface, and embedded controller is wired and programmed. Once that knowledge is captured, I want a refreshed design that removes today’s failure points and is ready for a short production run. Work starts with non-destructive teardown, high-resolution imaging, net tracing, and firmware dumping via JTAG/SWD or any other proven technique. From there the task moves into schematic recreation (Altium Designer or KiCad preferred), BOM generation with current compon...

I’m building an automated live-play poker table and need the complete RFID hardware blueprint that will let software read every chip on the felt in real time. The table will hold well over 100 tagged chips at once, and I want reliable High-Frequency (13.56 MHz) reads at a maximum distance of about 10 cm from the antennas under the layout. Your task is purely on the hardware side: define an architecture that can see each chip as stacks move, bets slide, and pots grow, then pass clean data to the software team through a simple API or wired interface of your choice. Key expectations • Robust HF antenna array layout sized for a poker table, including multiplexing strategy to handle >100 simultaneous tags without collisions or dead zones. • Reader, controller, and MCU/FPG...

I need a compact 2-4 channel analog MEMS microphone array built around an XMOS processor.

Your code should compile and run on the free tools from XMOS; please include any scripts or tuning utilities you rely on. Deliverables • Production-ready Gerbers, pick-and-place file, annotated schematic • BOM with supp...

I’m building a small-footprint PCB around the ESP32 that will serve as the core of several IoT devices. The board must expose reliable Wi-Fi, Bluetooth, and flexible sensor headers so it can drop straight into prototypes and low-volume production runs.

I have three existing Altium Designer projects that must be refreshed before the next manufacturing run at JLCPCB. Both the schematic and the board layout need attention. On the schematic side I already know the exact edits: a handful of parts have to be added or removed, several nets must be reassigned, and a few voltage- and current-related values updated. Once those changes are in place the PCB layouts have to be brought in line—rerouting where required, keeping the original board outlines and mechanical constraints intact, and making sure every DRC/ERC check comes up clean. When the files are solid I need a full, ready-for-upload manufacturing package: • Updated Altium project files (.PrjPcb, .SchDoc, .PcbDoc) • Gerber and NC-Drill set generated with JLCPCB’s ...

I need a full architecture and layout for an advanced, multi-sensor PCB that will regulate heating, cooling and humidity inside a pharmaceutical machine. The board must interface with temperature, humidity and proximity sensors as standard, while leaving room for additional inputs such as light, pressure, water-level and high/low-voltage detectors. All sensing channels have to support automatic failure detection so the system can trigger the right alarm—heater, compressor, open door, over/under temperature, over/under voltage, pressure deviation—without user intervention. On the connectivity side I want both wired and wireless options: LAN, USB, CAN-Bus and RS-485 for plant integration, plus a wireless link for cloud dashboards.

I need help turning three off-the-shelf modules now sitting in my glasses prototype—a USB 2.0 hub, a USB audio codec (mic plus stereo out) and a dual-channel Class-D amplifier—into one long, narrow board that can slide inside the temple arm. The space I have measured is roughly 80 mm × 15 mm, so the layout has to be linear rather than squarish, with components placed to keep the height profile as low as practical. The board will run exclusively from the host’s 5 V USB rail; no batteries or additional supplies are planned. Because this is for voice prompts and basic media playback, a standard-grade codec is fine—I’m not chasing audiophile specs, just dependable microphone input and clean stereo output that won’t hiss or pop when the amp is idle. A...

Oil pipelines are commonly buried 3–5 feet beneath riverbeds to protect them from environmental exposure and mechanical damage. However, riverbed scour and sediment transport during floods or strong flow events may remove sediment and potentially expose the buried pipeline. Continuous monitoring of riverbed elevation is therefore essential to ensure pipeline safety and to understand sediment dynamics. This project proposes a Smart Rock monitoring system designed to measure riverbed scour and elevation changes. Each Smart Rock contains an embedded absolute pressure sensor that measures water pressure to estimate local water depth. By combining these measurements with the absolute water surface elevation, the absolute elevation of each Smart Rock can be determined. Since the pipeline ...

I want to build a small, self-contained charging station that wakes up only when it “sees” a bottle and a can. The core will be an Arduino (any recent 32-bit board is fine) tied to a solar panel and battery pack. A lightweight AI vision module or camera running something like TensorFlow Lite or OpenCV should continuously—or on a duty-cycled basis—look for bottles. The moment a bottle is detected, the system must move straight into the charging routine without waiting for external confirmation; no alerts, no logging, just automatic activation. What I need from you • Complete Arduino firmware that integrates the vision trigger with the charge-controller logic. • A schematic / wiring diagram showing how the camera, solar panel, charge controller, and any...

I have already drafted a full specification for a simplified television remote control aimed at older users, complete with ergonomics, button layout, and overall product vision. While I finish the patent application, I now need a skilled partner to bring the electronics and software to life. On the hardware side, the priority is circuit design.
