    I am working on a compact RF application based on Silicon Labs’ SI4010 transmitter and now need a fresh set of expert eyes to get it production-ready. The hardware is already roughed-in and the core firmware skeleton is compiling, but performance still falls short of our targets in range, spectral cleanliness, and power efficiency. Your task spans three focused areas: • Schematic & PCB audit – flag layout, matching-network, or decoupling choices that could be detuning the front end. • Firmware tuning – refine register settings, timing, and wake-sleep sequencing in the SI4010 API so we hit our duty-cycle and current-draw goals without sacrificing link reliability. • Validation – document improvements with spectrum-analyzer plots, RSSI ver...

    I’m looking for an engineer or a small team to deliver a working prototype of the electronics for a automated shutter project. The system runs on 24V DC and drives two brushed DC motors (each actuator delivers roughly 50 Nm at the output shaft through mechanical gearing). The electronics will sit inside the actuator housing, and I want Wi-Fi connectivity with Home Assistant integration (preferably ESPHome, MQTT is also fine). My preference is one ESP32 controlling both motors, with encoders (A/B) on each output shaft. I will not use limit switches, so the design should include reliable end-position handling without them: travel learning/calibration, position tracking via encoders, and safe stopping based on current sensing and/or “PWM commanded but encoder not moving” l...

    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 outputs range from 20V to 5V. The Pi should get power from the HAT on the I/O pins. Power over Ethernet as a power input would be great but it is not mandatory.

    My heating installation is already wired with motorised valves and PT-100 temperature sensors; what it still needs is a clean, reliable control program running on a Schneider Electric PLC. All field devices will communicate over Modbus TCP/IP, so the job centres on writing and testing the logic that opens or closes each valve, reads every sensor, and enforces the temperature set-points and safety limits I will provide. You’ll work directly in EcoStruxure Control Expert (Unity Pro), mapping the correct holding/input registers, building the sequence logic (ladder or structured text—your choice), and setting up alarms and manual-override modes. Once the code is ready, I’ll load it on site; remote commissioning support through VPN is essential to fine-tune timing and confirm...

    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
    4 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...
