I am building a proof-of-concept 2D LiDAR unit from the ground up and need a mainland-based embedded electronics engineer who can handle every step of the design and bring-up process. The goal is a compact indoor scanner that excels at obstacle detection and terrain mapping while holding tight, high-accuracy tolerances. What the work involves You will take the idea from blank sheet to working board: optical layout, high-speed signal processing, motor/galvo drive, power management, firmware, and a simple USB/TTL data interface that streams polar coordinates for fusion in my existing SLAM stack. Expect heavy use of Altium (or KiCad), STM32/ESP32 class MCUs, precise timing control in C/C++, and low-level debugging with J-Link or OpenOCD. I will handle mechanical housing once you define env...

Engineering Proposal – Slim Custom Jewellery Tablet (MVP) We are looking for an engineering partner to develop a slim, premium, purpose-built touchscreen tablet for our jewellery business. The device will run our proprietary jewellery software and should provide a complete integrated solution: * High-quality touchscreen optimized for jewellery images/design exploration * Android-based embedded system or another suitable OS * Processor, RAM, storage and Wi-Fi * No camera required * Slim, lightweight custom enclosure * Reliable power/battery system * Automatic launch of our application on startup * Kiosk/locked-device mode * Internet/cloud connectivity * Local database and synchronization * Jewellery gallery and product exploration * Jewellery creation/configuration * Customer and prod...

I need a complete electronic hardware solution for a therapeutic, drug-delivery device that administers medication via inhalation. The brief covers everything from early-stage architecture to a working, testable prototype. The hardware must precisely control dose release, monitor key parameters such as airflow and temperature, and log usage data for later analysis. Size, power consumption, and patient safety are critical. Expect the design to comply with IEC-60601 and ISO-13485 principles, ready for eventual regulatory submission. To keep the project clear, here is what I expect to receive: • Detailed schematics and PCB layout files (Altium, KiCad, or similar) • Component-level bill of materials with sourcing information • Firmware source code to drive sensors, act...

I will supply a complete schematic, dimensioned drawing, and parts list for a small 90 × 190 × 40 mm panel that holds four illuminated push-buttons, two status LEDs, a few relays/diodes, and screw-terminal break-outs for power plus two simple on/off inputs. Every component value, wire gauge, and mechanical placement is already locked down; there is no design work left to do. Your task is purely hands-on: build one fully-functional unit exactly to the drawings. I’d like the circuitry laid out on stripboard (or another point-to-point method you’re comfortable with), all joints soldered, and the harness inside the enclosure bundled neatly for strain relief and easy future service. The case itself should be plastic, as noted in the documents. Before shipping the finis...

I already have a complete schematic for my single-phase energy-monitoring circuit; what I need now is a production-ready PCB layout that faithfully follows it and fits the enclosure I have chosen. The board must match the exact outline and mounting-hole pattern of my reference enclosure, so you will get the enclosure model and mechanical drawings from me on day one. Once the layout is finished, I will need the full Gerber/NC drill set along with the editable design file so I can review trace widths, clearances, and layer stack-up before we send it to fabrication. Deliverables: • Complete, error-free Gerber and drill files • Native design file (Altium, KiCad, or similar—your choice) • Brief design report highlighting key layout decisions and any DRC/DFM notes ...

I need a full-stack hardware designer to turn my concept into a manufacturable prototype board built around Rockchip’s RV1126B. The board must carry 2 GB LPDDR4X, a 32 GB eMMC, microSD slot, on-module Wi-Fi/Bluetooth, and a MIPI-DSI connector that will drive a touch display used strictly for user interface and control. Because this is a prototyping/testing build, I am happy to iterate, but the first revision should already be hand-solderable or assembly-ready at common fabs. Key integrations • Two USB 2.0 ports will each host an external Wi-Fi video receiver; please validate bandwidth and power budgets. • An existing STM32F405-based SkyBrain RC subsystem must be brought onto the same PCB (or docked through a high-speed mezzanine) so every one of its functions—...

I’m building a 150 W power-supply card that will live inside industrial machinery and must keep running in a harsh environment riddled with temperature swings, vibration, dust and electrical noise. The board has to deliver two isolated outputs—24 V for the actuators and 5 V for the control logic—at the same time, with total combined power not less than 150 W. (Discreet preferred, can go with module-based also) I need a complete, production-ready design package: schematic, PCB layout, annotated BOM with orderable parts, and all fabrication files. Thermal modelling, component derating and clearances should reflect industrial-grade safety (IEC/UL standards) and 24/7 duty cycles. I’m fine with Altium, KiCad or OrCAD as long as the files are editable in Altium. Before ...

I need a working prototype of a portable SIM-bonding unit that merges multiple 4G LTE links to deliver a single, higher-bandwidth connection and tunnels all traffic through an IPSec VPN. Scope of work • Hardware: board design, enclosure, integrated high-gain antenna, SIM tray/slots (minimum 4), battery and power-management circuitry. • Firmware: real-time link aggregation logic, automatic cell reselection, fail-over, IPSec client with configurable policies, and a simple captive portal or serial console for first-time setup. • Management software: web UI plus optional CLI/REST API to show bonded throughput, per-SIM stats, signal strength and VPN status, with secure remote firmware-upgrade capability. • Documentation: schematics, BOM, mechanical drawings, firmw...
