I have a Siemens IOT2040 already running Node-RED and two flow-meters that expose their readings over Modbus registers. I need a clean flow that polls those two devices, keeps the register map exactly as it is, and republishes the same data over Modbus TCP so a Crimson-based PLC on the other side can read it without extra parsing or scaling. There is no data pre-processing involved: whatever the meters expose is what the Crimson PLC must see. All I’m after is a reliable bridge with tidy, documented Node-RED nodes and comments so future edits are easy. Deliverables and Remote Work: 1- I will provide access to Red node and computer connected to the IOT - work can be done remote connection or on your workstation then imported here, 2- There will be UIs on the Node Red to see wh...

I need an engineer to take my concept for a high-voltage DC-DC converter and translate it into a complete, build-ready design that slots straight into a renewable-energy storage setup. The converter will accept 24 V DC at the input and deliver a regulated 165 V DC output. Efficiency, thermal management, and long-term reliability matter far more to me than squeezing every last cent out of the BOM, so component quality and sound topology choices come first. You will own the full electrical design flow—topology selection, key-component sizing, magnetics specification, control strategy, and all supporting calculations. I expect LTspice or an equivalent simulation environment to demonstrate stability, transient response, and efficiency before we move on to hardware. Once the numbers look...

I already have a solid Beckhoff TwinCAT program running one of our stations stations. I now need that proven logic adapted and commissioned on a second, nearly identical arm so it operates just as reliably. The work starts with reviewing the existing TwinCAT 3 project, mapping the EtherCAT I/O for the new cabinet, tweaking motion parameters where the mechanics differ, and then loading everything to the CX controller. After deployment, I will need the full functional test: start/stop, homing, safety chains, and a complete production cycle to prove repeatability. Once the arm is cycling cleanly, spend some time beside the line with my maintenance crew. A practical “teach-as-we-go” session is perfect—show them how to tweak set-points, clear common faults, and pull updated ...

I’m putting together a dedicated, distraction-free reading device and need a hardware specialist who can take it from concept to working prototype. The display has to be an AMOLED panel of at least 11 inches—no compromises on that vibrant contrast. This will be a reading-only tablet, so efficiency, eye comfort, and battery life have priority over raw processing power. Wireless connectivity is essential for loading books and updates; Wi-Fi is mandatory, Bluetooth is optional. In addition, I want physical page-turn buttons on the bezel so users can flip pages without touching the screen. Touch input itself is welcome but not a requirement. Here’s what I’m expecting from you: • Source and validate the 11″+ AMOLED display and its driver board • Desi...

My Euroart JG168BL dual-zone wine fridge is stuck on an E4 error, which points to a faulty NTC temperature sensor in the upper chamber.

I need to reproduce every technical element of a published study on an Electric Vehicle dual-charging system inside MATLAB/Simulink. That means rebuilding the paper’s mathematical models, running the same simulations, and then matching the resulting plots, tables and efficiency numbers through solid data analysis. I already have the PDF and a partial set of parameters (converter ratings, battery specs, and a few controller gains), yet several key values are missing. Your first task will be to track down or logically derive those gaps so the model behaves exactly as described by the authors. You’ll be working in MATLAB R2025a (Simulink + Simscape Electrical). Each subsystem—DC-DC converters, dual-port charger topology, control loops, and SOC estimation—must be orga...

I need a clear and professionally drafted electrical single-line diagram based on the electrical load list along with safety features that shows how power will be distributed throughout a small-scale gas plant facility. The drawing must follow the NEC (National Electrical Code) so that it can be submitted directly to our local authority for review and later handed to the construction team without additional rework. Scope of work – Capture the complete power distribution path from the utility tie-in through to all downstream loads, including metering points and breaker information. – Use standard electrical symbology and layer naming so I can easily integrate the file into our master AutoCAD set. A clean PDF export is also required for circulation.

I am looking for an engineer or team that has already completed full-scale retrofits on large-format CNC equipment and can bring an HB03/TS150 JUARISTI up to today’s standards. The scope is comprehensive: the control system must be replaced, all electrical components re-engineered and rewired, and the mechanical assemblies fully overhauled so the machine leaves the shop in “as-new” condition. What matters most to me is proven experience integrating modern CNC controls into legacy iron without compromising accuracy or rigidity. If you have recently worked with Siemens, Fanuc, Heidenhain—or another controller you feel is better suited—let’s discuss the architecture you would recommend and why. Likewise, I’d like to hear how you handle mechanical scr...

For my current university project I have to build a compact PCB whose only job is to collect data from several temperature sensors and route those readings to the rest of my prototype through simple wired connectors.

I already have a data table that lists torque, phase-U voltage and current at several operating frequencies under two control modes: the ordinary V/f scheme and the 87 Hz extension. The figures I plotted from that table are wrong, so I need them rebuilt from scratch in MATLAB. Scope • Write a clean, well-commented MATLAB script (or live script) that reads the table, calculates the required values where necessary, and then produces accurate plots of torque, voltage and current versus frequency. • Each plot must overlay the two operating modes—standard V/f and 87 Hz—to highlight their differences up to the 50 Hz corner frequency. Beyond that point only the 87 Hz data continues, exactly as in the table. • Axis labels, legends, units and titles should be clear...

Project Brief: Stealth-Modified Automatic Parking Disc (Certified for Public Road Use in Germany) Project Goal: I want to technically modify a certified electronic parking disc approved for use in Germany (must have an official certification number and ECE approval), so that it continues to automatically update the displayed parking time even after the vehicle has been parked. This modification must be invisible and undetectable from the outside, meaning the device must look and behave like the original product to any observer or parking enforcement officer. Background: Standard electronic parking discs are designed to detect when a vehicle is turned off and then freeze the display at the next permissible half-hour mark. This allows parking enforcement to determine how long the car has b...

I’m arranging a series of one-hour classes that blend hardware design (VLSI and PCB) with software development in Python and Java.

I maintain a fleet of mission-critical electronic control boards that must run flawlessly around the clock. Although the hardware is operational, I want to squeeze every last drop of performance out of it and harden the supporting security stack. Your focus will be on two fronts that matter most right now: • Bench-testing the optocouplers and comparators on the boards, then fine-tuning or replacing any part that introduces noise, latency, or inconsistent thresholds. RS-485 paths are already stable, so your insights should drill straight into these analogue front-end components. • Re-creating my SOC lab scenarios, walking through the logs, alerts, and incident chains, and flagging bottlenecks or mis-tuned rules that slow response time. Packet captures, SIEM exports, and a fu...

I’m updating the lighting throughout my house and need a clear, well-thought-out plan that focuses on functional use. The scope covers the living room, kitchen, and all bedrooms.

Because the blowers and DAF units must tie cleanly into the electrical network, you will be leading the electrical connections and integrations as well—paying particular attention to insulation and protection so we avoid any start-up surprises. I am counting on a Mechanical Engineering graduate with 5–10 years of industr...

I have a production-ready, IGBT full-bridge welding inverter that already powers both TIG and MMA processes, yet the embedded side still needs a final expert pass before release. The control board is built around 8051 and STC MCUs running Keil C51 firmware, and every line of code directly shapes arc stability, HF start, AC balance, soft-start, and safety interlocks. The short-term goal: review, tidy, and extend the existing code so it drives the power stage flawlessly in TIG and MMA, AC and DC. That means refining PWM timing, gate-drive dead-time, current-feedback filtering, and all the little state-machine details that separate a decent welder from a great one. Core tasks and deliverables • Audit the present C51 codebase, flagging race conditions or timing pitfalls. • Im...
