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...

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. Everything must be laid out and modelled inside Fusion 360, right down to the housing that will protect the board once it is fabricated. Here is what I need from you: • Create the full schematic and board layout in Fusion 360’s electronics workspace, optimised for straightforward sensor-integration and robust wired headers. • Export clean Gerber/Drill files plus the native Fusion 360 design so I can iterate later. • Model a 3-D printable enclosure in the same project file, dimensioned precisely to the finished PCB, with openings for the temperature-...

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 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...

I’m putting together a small interface that lets a 5 V logic line drive a 12 V DC mechanical relay while keeping the control electronics completely isolated from the field wiring. My plan is to repurpose an off-the-shelf two-channel relay module for the load side and pair it with a standard optocoupler breakout on the control side; you can choose whichever optocoupler best meets the brief as long as it fits the isolation goal. What I need from you is a concise, ready-to-build circuit design: • A clear schematic showing the 5 V input network, the optocoupler stage, any necessary current-limiting or pull-down components, fly-back diode protection for the 12 V coil, and the wiring to the relay board. • A bill of materials with exact part numbers so I can order everything imm...
