I’m rolling out a new generation of eco-friendly EV charging stations and need a full-featured management platform built from scratch. Here’s what the first release must do for me: • Energy usage monitoring for every session and charger • Remote control—start, stop, reboot and schedule charging • Secure user authentication Role-based access is essential. Administrators configure the network and view global analytics, end-users simply authenticate and charge, while maintenance staff receive real-time diagnostics and alerts. The platform must also talk seamlessly to our existing energy-management system through open, well-documented APIs so we can optimise load and incorporate on-site renewables. REST/JSON is preferred, but I’m open to ...

I need a working proof-of-concept that hardens my wireless network by analysing live traffic and flagging hostile activity the moment it appears. The model must reliably catch the attacks that worry me most: Denial of Service (DoS), Man-in-the-Middle (MitM) intrusions, classic packet sniffing, and ARP spoofing. Everything has to run in real time on a modest on-prem machine, so efficient feature extraction and lightweight inference are a priority. The task breaks down naturally into three parts. First, capture and label representative WLAN traffic—public datasets are fine as a starting point, but I also want a small tool that lets me pipe raw pcap streams into the training set so the system can learn my network's quirks. Second, build and train the detection engine: a wel...

I already have three published papers on electric-vehicle charging and a university-approved thesis template. Your mission is to mould those papers into one seamless Ph.D. dissertation, written and typeset entirely in LaTeX on Overleaf. You will receive: • the official structure document my faculty expects • the full set of formatting and submission guidelines • the three peer-reviewed articles (source files and PDFs) What I need from you is a logically connected thesis that: 1. Re-orders, edits, and links the existing papers into unified chapters (intro, literature review, methods, results, discussion, conclusion) while preserving each study’s integrity. 2. Adds any bridging text, contextual background, extended literature coverage, and future-work ...

I need a compact, production-ready circuit that brings reliable wireless communication to a new consumer-electronics device. The work begins with schematic capture and component selection, moves through PCB layout, and finishes with ready-to-manufacture Gerbers, a complete BOM, and clear test guidelines. The radio link is the heart of the design, so careful RF layout, antenna matching, and regulatory-compliant power levels are essential. Bluetooth LE is my preferred protocol, though I am open to Wi-Fi or other 2.4 GHz solutions if you can demonstrate lower cost or better battery life without sacrificing performance. Please plan on: • Delivering editable design files in Altium, KiCad, or Eagle, plus PDFs for quick review • Calling out any critical components with ...

...opening cartons. Now I need to see it come to life in the form of one or two fully working prototypes that prove every feature actually functions. Functionality and quality are my top priorities. The prototypes have to write cleanly, shine a steady laser, and retract the blade the instant pressure is released. To make that viable all day, battery life and a convenient USB-C (or similarly compact) charging solution are non-negotiable. Safety is equally critical: the laser must include recessed button for activation, and the ceramic blade mechanism must lock away reliably inside the body. The housing should showcase a seamless blend of brushed aluminium and stainless steel so it looks and feels like professional surgical instrumentation while keeping weight balanced in hand. Ergo...

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 &bul...

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 ...

My spare MacBook has suddenly stopped seeing any wireless networks, even though the other computer on the same desk is happily online. I’m on macOS and, so far, the affected machine can’t detect a single network—home, hotspot, or neighbour—so it’s not just my router. What I need from you is a real-time remote session (Zoom, TeamViewer, or your preferred secure tool) to: • diagnose why the Wi-Fi interface is blind • walk me through any Terminal commands, SMC/PRAM resets, or network-interface reinstalls required • verify that the Mac can once again scan, join, and hold a stable connection I’ll stay on the working computer throughout our session for screen sharing and chat, and I can reboot the faulty Mac as many times as n...

I need a fast, professional Ekahau site survey so I can design a rock-solid wireless network for our warehouse.

I’m looking for an experienced PCB design engineer to create a compact PCB that integrates LTE and GPS functionalities in a single module. The design must include onboard antennas for both LTE and GPS, a charging circuit, and debugging options. All other design and component details will be discussed over chat. --- Functional Features (Antenna Design Requirements): The PCB should include onboard antennas for both LTE and GPS, similar to the integrated antenna design used in ESP32 modules. Antennas must be PCB-etched or chip-type, without external connectors. Proper RF impedance matching (50Ω) and matching networks should be implemented for both antennas. Ensure antenna isolation, ground clearance, and tuning for optimal LTE and GPS signal performance. Include ant...

I have a clean AutoCAD master file and clear mark-ups that show exactly where each speaker, wireless access point, camera, and lighting keypad belongs on every floor. What I need now is a polished set of four separate drawings—one for each device type—where those points are inserted on every floor plan and identified with standard industry symbols and call-outs. The locations are already determined, so this is primarily a drafting and annotation task: copy the base plan, drop in the symbols at the marked coordinates, label them in a way any integrator will immediately understand, and keep the layers tidy so the elements can be toggled on or off later. Deliverables • Four DWG files (Speakers, WAPs, Cameras, Keypads) reflecting all floors • Matching PDF...
