    I need an experienced electrical engineer who can hit the ground running on-site in the Netherlands to commission industrial automation and control systems that are driven by Programmable Logic Controllers (PLCs). The equipment is already installed; what is missing is the final push—power-up, I/O checks, logic verification, and system acceptance—so production can start without a hitch. You will interface with my local installation crew, review and, where necessary, fine-tune the PLC code, walk the operators through functional testing, and generate the documentation required for hand-over. Familiarity with the usual suspects—Siemens, Allen-Bradley or comparable platforms—is essential, as is a pragmatic attitude toward safety and EU compliance. Deliverables I ex...

    I want a Raspberry Pi HAT that accepts a single USB-C PD input and breaks it out into three or four downstream USB-C ports that carry both power and data. Each of the three outputs should be able to negotiate its own Power Delivery profile while maintaining a reliable high-speed data link to the Pi (think USB 3 where practical, at least USB 2 if trace lengths make higher speeds unfeasible). Physical limits are the standard HAT outline, with decent thermal relief so the board can handle a fully-loaded 100W input without throttling. I am open to component choices.

The codebase already compiles and runs on the microcontroller, but several features still require clean, well-structured implementation, performance tuning and thorough testing directly on the hardware. You’ll be working exclusively with STM32 microcontrollers; no FPGA or other targets are involved. Please be ready to pull the current CubeIDE project from my repository, build it as-is, and then extend it in C++17 (or later) while respecting the existing HAL layer and project structure. Deliverables • Updated CubeIDE project with the new or fixed functionality fully integrated • Clear build instructions and a short change log so I can ...

    I am seeking a US-based hardware developer or electronics technician to assemble two physical prototypes of an RF-based proximity system. I have already developed the full source code and circuit schematics; however, due to a physical disability, I require a partner to handle the soldering, wiring, and physical housing of the components. Technical Requirements The project consists of two separate units: a Transmitter and a Receiver. Microcontrollers: Program and integrate 2x Arduino boards (provided/specified in schematics). Connectivity: Configure RF modules for proximity detection. Power: Integrate rechargeable battery systems (Li-Po or similar) with charging ports for both units. Assembly: Solder all components according to provided schematics. Enclosure: Mount...

    1) Project goal Design a single PCB device for testing cable harnesses up to 25 wires, where both ends of the same harness are connected to the board: Side A: 25 lines (A1..A25) Side B: 25 lines (B1..B25) Total: 50 signal lines on the PCB. The detailed test logic (continuity/shorts/mapping) will be implemented in firmware later. For this phase, the key deliverable is robust hardware (schematic + PCB) prepared for such testing. 2) Scope of work (hardware only) Electrical schematic PCB layout Production files: Gerbers + drill BOM (with specs and acceptable alternatives) Assembly files (pick&place/positions) preferred Short mapping table: MCP23017 pins → A/B line numbers (Firmware is NOT required in this phase. Optional “I2C scan / basic blink” is a bonus.) 3...

    I need an embedded engineer to help safely connect a PCB to a lead-acid battery pack in series and integrate 4 external sensors (temperature, humidity, water presence, etc.). The system must read data in Arduino IDE and, if possible, send it to an existing telemetry endpoint (HTTP/MQTT). Scope: Safe wiring from battery pack to PCB Best way to connect and mount sensors Connector and grounding recommendations Simple Arduino example to read sensors and output/send data Experience with ESP32, Arduino, sensors, and battery-powered systems required.

    I am midway through an online electrical training program and still have two graded components left in each module: the “learning activity” and the “content quiz.” Both are multiple-choice, can be retaken without limit, and I need a final score of 90 % or higher on every attempt that counts toward my record. You will receive screen-shots of every unfinished unit plus login access so you can work directly in the platform. Feel free to lean on AI tools or any personal reference material; the school places no restriction on outside resources. When you reply, please mention any hands-on electrical background, coursework, or certifications that show you can navigate these topics confidently. Deliverables • All remaining learning activities submitted with ≥...

    IEEE 33-Bus RTDS Model
    3 days left
    Verified

    I would like the IEEE 33-bus distribution feeder recreated in RSCAD v6 so that it runs smoothly in real time on my single-rack RTDS. The base network must be stable, clearly documented inside the workspace, and organised under three separate simulation cases: 1. Baseline (no DER, no EV) 2. PV + BESS + EVCS with V2G enabled 3. EVCS with V2G only I’ll provide the complete MATLAB data set that defines the component ratings, daily profiles, dispatch assumptions and any controller logic already worked out offline. Your task is to translate all of that into RSCAD, verify compile/run success at a 50 µs timestep, and deliver a balanced model that can be opened and executed immediately on the RTDS without further edits. Please let me know: • Your earliest start date and est...

    I’m looking for an experienced aftermarket specialist to help me squeeze more performance out of my sports car. The priority is performance upgrades, starting with an aggressive body-kit package and any complementary tweaks that will genuinely improve aerodynamics, handling, and acceleration without compromising reliability. Here’s what I have in mind: • Custom-fit body kit installation and precise alignment • Suggestions on any additional performance parts that pair well with the kit (intake, exhaust, ECU remap, suspension fine-tune, or upgraded brakes if they add measurable gains) I’ll provide the car, workspace access, and all agreed-upon parts in advance. Your role is to advise on the optimal kit, confirm compatibility, carry out the install, and road-te...

    I have been subjected to to “voice-to-skull” transmission, direct energy weapon and remote neural monitoring(remotely). My main concern right now is the physical discomfort it is causing—persistent headaches, muscle pain, fatigue, blurred vision,disorder sleep and many other things. I need help to stop it. You must have knowledge about RF wave, WIFI wave. Here is what I expect from you: • A brief consultation (voice or message) where you help me describe my symptoms and living environment in enough detail for an accurate assessment. • A written action plan that includes: – Practical counter-measures I can put in place immediately (shielding materials, RF detection equipment, grounding techniques, etc.). – Any recommended tools or devi...
