I’m putting together a straightforward location-tracking system for loads of non-perishable goods that move through warehouses, trucks, and rail cars. The core requirement is real-time position updates from departure to storage, with automatic alerts if a device signals potential theft. The hardware can be either single-use—so the receiver never has to return or recharge the tag—or a reusable unit that we can redeploy after each trip. I’ll need your help scoping both variants and producing an estimated cost per device for each. What I expect from you • A concise technical proposal outlining the recommended tracker form factor, network technology (e.g., GSM, LTE-M, NB-IoT, LoRaWAN), and back-end platform or API you plan to leverage. • A table or brie...

I need an Android application that authenticates against a Pepperstone cTrader account through the official cTrader Open API using the Implicit Grant flow. After sign-in, the user must be able to: • securely fetch and display current account balances, open positions, and full account history • place, modify, and close trades from both demo and live accounts Push notifications are not required, so everything should happen in-app. Please follow cTrader’s recommended OAuth security practices, store tokens safely, and make sure the same codebase can be switched between demo and live environments with a simple build flag or configuration file. Deliverables must include: • a clean Android Studio project (Kotlin or Java) that compiles without external tweaks • doc...

I need a complete high-frequency RF PCB laid out in KiCad for a signal-processing application. The board must integrate antennas directly on the substrate; no filters or discrete amplifiers are planned at this stage, so every trace, via, and ground return has to be optimized for clean, low-loss feed to the antenna structure. Scope • Translate my existing schematic (KiCad format) into a production-ready multilayer layout. • Model and route all RF paths with controlled impedance, proper stack-up definition, and tight clearance to meet high-frequency performance targets. • Design and tune the on-board antenna geometry, matching network, and keep-out regions inside KiCad’s PCB editor and 3D viewer. • Run DRC, ERC, and any KiCad integrated RF simulation tools ...

I need a purpose-built software package that lets me run my CNC‐based 3D printers from a single, intuitive interface. The focus is on day-to-day control and operation rather than design work: loading G-code, managing multi-axis motion, optimizing toolpaths on the fly, and keeping a constant eye on temperatures, feeds, and sensor feedback without pausing a job. The machines on my floor vary, so the application has to drive everything from a straightforward FDM gantry to more complex SLA and SLS setups. That means kinematics for rotary or additional linear axes, stepless speed changes, and smart re-slicing or re-planning if a collision or out-of-range condition is detected. Real-time monitoring is non-negotiable; I want live dashboards that surface spindle speed, laser power, material flow,...

I still have a working copy of our old “export” utility--a small .NET Windows Forms program that pulls voice recordings from our recorder software through its SDK--but the original source code is gone. I need someone who can decompile that executable, clean up the recovered code, and then refactor the tool so it runs purely from the Windows command prompt. Instead of the current dialog box, the new build must accept: • a start time and end time parameter that define the export window • a list of one or more phone extensions to filter the recordings Everything else about the workflow stays the same: the program will talk to the recorder SDK, fetch the selected recordings, and drop the files into a local folder on the same server where the recorder software already ...

I’m looking for an experienced FPGA engineer to create a one-off firmware build for an Artix-7–based LeetDMA/Screamer PCIe DMA card. The goal is to make the card appear on the bus exactly like my reference network interface card so automated heuristic checks see no difference. Scope of work • Re-order and modify the Capability Pointer chain inside so the PCIe config space layout mirrors the donor NIC byte-for-byte. • Implement full TLP transaction handling, including correct completion timing and status codes. • Provide accurate BAR sizing and address decoding as the original NIC does. • Add proper MSI / MSI-X interrupt setup with working vectors and masking logic. Context and constraints This firmware is for security research, not production ...

My 3D scanner streams PCD point-cloud files that contain spiral-shank bolts mixed with other hardware. I need a compact, CUDA-friendly C++ solution that runs directly on an NVIDIA Jetson Orin NX, spots every bolt in each cloud, records the head-center XYZ (and, if practical, its axis direction), and writes the results to a structured XML file. Performance targets • Accuracy: at least 95 % correct identification on the annotated dataset I will supply. • Speed: real-time or near real-time processing on the Orin NX under the standard JetPack image. You are welcome to build on open-source libraries such as PCL, Open3D, Eigen, cuBLAS or TensorRT, provided everything can be compiled through CMake and redistributed without license issues. Deliverables • Well-documented...

I operate a workshop that produces detailed limestone carvings on a CNC machine and I’m looking for a programmer who can take my artistic concepts all the way through to proven, ready-to-run code. Your core mission is 3-axis, 3D carving and modeling: preparing clean toolpaths that cut complex reliefs and sculptures accurately in limestone without chipping, chatter, or unnecessary machine time. You are free to work in Fusion 360, VCarve, Mastercam, or any other CAM environment you prefer—what matters is a smooth workflow and reliable results. I will supply either surface models or sketches; you translate them into optimized roughing and finishing strategies, simulate everything, and deliver the final G-code along with a brief setup sheet so my operator can load it and press Sta...

I need a Python-based 2D game that captures a classic space theme and runs smoothly on PC. I already have the core concept sketched out—think fast-paced arcade action set against a scrolling star field—but I want you to handle every technical detail from setting up the Pygame (or similar) framework through to packaging a playable build. Key goals • Core loop: player-controlled ship, enemy waves, scoring, basic power-ups. • Clean, modular code so I can expand levels or tweak mechanics later. • Lightweight graphics and sound assets that fit the retro space aesthetic (original or royalty-free). • Final deliverable must run on Windows without extra installs beyond Python itself; include an easy installer or clear README. Please include in your proposal...

I need a Windows application to automate a PS5 user-switching workflow shown in my video. The software should use an HDMI capture card and computer vision (OpenCV/template matching/OCR) to detect what is currently displayed on the PS5 before performing each action. I do NOT want a simple fixed-delay macro. Workflow: Private Match → PS5 Control Center → Profile → Switch User → select next pre-added profile → return to the game → handle “Your profile was signed out” if shown → wait for “Downloading Game Settings” to finish → verify Private Match is loaded again → automatically repeat with the next profile. The developer must also provide a reliable method for the Windows PC to send controller inputs to the PS5, including...

Zephyr and LVGL developer: build 5 navigation models for a smartwatch OS We build MintWatch, a 454x454 round AMOLED watch running our own OS. The firmware is Zephyr with LVGL, written in C, and it builds today for native_sim on a desktop as well as for the watch silicon, so you can do this entire job on your own machine with no hardware. We need five new operating system models added to the existing set. What a model is here A model is not a theme. Our tree already separates the two, and this job is only the first half: Home: what is on the screen when the wearer is doing nothing. A watchface, an app grid, a conversation, a scrolling list of text. These are different devices, not different skins. Navigation: what every gesture does from home. Peers on a line, sheets over a home, cards in a...

I need an embedded developer who can write reliable, production-ready firmware that squeezes extra performance from aftermarket automotive modules. The immediate focus is on three devices: • CNG timing advancers • O2 optimizers • CKP sensors The end goal is measurable performance improvement, not just basic functionality, so timing accuracy, fast signal processing and rock-solid stability are essential. I am not certain whether any legacy code exists for these boards; you may be starting from a clean slate or refining half-finished firmware. Either way, I will supply the hardware, electrical schematics, and any reference data I can gather. You will advise on toolchains, microcontroller families and calibration workflows, then deliver: • Complete, compile-ready...

I’m working on a personal project that leans heavily on SymPy, and I’ve hit a limitation with the way the library handles division when both operands are integers. What I need is a clean modification to SymPy’s source so I can keep every operation strictly in the integer domain—avoiding automatic promotion to Rational objects—while preserving all of SymPy’s usual behaviour for non-integer or mixed-type inputs. Here’s what the job entails: • Identify the precise spot in SymPy’s core (likely sympy/core/ or related) where integer division is resolved. • Implement a path that returns the floor-divided Integer result (e.g. 7/3 → 2) or, if you prefer, expose a switch/flag or subclass that activates this behaviour only when reques...

I’m looking for a skilled mechatronics specialist who can jump straight into the electrical and software-programming sides of my machine-building project. The mechanical portion is already under control in-house, so your focus will be integrating, testing, and refining the control electronics and embedded code that drive the system. You should be comfortable reading and updating wiring schematics, selecting or replacing critical components, and writing clean, well-documented firmware or PLC logic that keeps everything running reliably. If you can also implement quick diagnostic routines and safety interlocks, even better. Scope at a glance • Review existing electrical design, spot weak points, propose improvements • Develop or optimise the control software (C/C++, Pyt...

I want to automate our technical-support channel on WhatsApp so customers can get instant answers to their most common questions without ever waiting for a live agent. The flow should be entirely rule-based: the bot simply matches incoming messages to a predefined set of question-and-answer pairs and replies with the correct solution. No natural-language processing is required at this stage; clear, deterministic logic is preferred because it keeps maintenance simple and ensures answers remain accurate. I will supply the full list of frequently asked questions (FAQs) and their responses. Your job is to build the WhatsApp Business API (or a reliable provider such as Twilio or 360dialog) integration, create the decision tree that recognises each FAQ keyword or short phrase, and return the co...

أريد بناء لعبة قتالية ثنائية الأبعاد تلهمها Shadow Fight لكن بروح مختلفة تماماً. سأقدم لك القصة والأفكار الرئيسية، بينما أتوقع منك تنفيذ اللعبة كاملة باستخدام ‎HTML5/JavaScript‎ أو أي محرك خفيف يتيح النشر على الويب والهواتف. الفكرة ينتشر فيروس غامض يمنح بعض البشر قوى خارقة؛ منهم من يوظفها لحماية الآخرين، ومنهم من يستغلها لنشر الفساد، فيما يتحول بعض الضحايا إلى وحوش مفترسة. اللاعب يختار بطله المفضل ويمضي في حملة قصصية تتدرج عبر مدن مهدَّمة ثم مختبرات سرية وصولاً إلى معقل الزعيم الأخير. الرسومات أحتاج أسلوب رسوم متحركة كرتونية بألوان واضحة وتفاصيل تُظهر ملامح الشخصيات والأسلحة، لا ظلال سوداء. الواجهات والقوائم يجب أن تبدو حديثة وتعمل باللمس بسلاسة. الخصوم • بشر بأسلحة وتقنيات متطورة • وحوش بقدرات خارقة • كائنات هجينة تجمع بين ميزات الاثنين خصائص اللعب –...

The goal is to launch a new TRC-20 cryptocurrency on the Tron network that ships with three core capabilities: native wallet support, real-time transaction tracking, and an on-chain staking mechanism. Token creation should follow current best practices for Tron smart contracts, including upgradability and pausable safeguards. Once the contract is live, I will need seamless wallet integration so holders can store, send, and receive the coin through both mobile and web extensions (TronLink, Trust Wallet, etc.). A lightweight block-explorer style dashboard or API that surfaces transfers, balances, and staking statistics in real time must accompany the launch so activity is always transparent. Staking is central to the token’s utility: users should be able to lock their balance for...

I need a specialist to build the core firmware. The brain of the machine is an STM32 MCU and it must coordinate three key subsystems—motors, heaters, and fans—through a pair of Trinamic drivers (TMC2209 and TMC5160). Your code will run in Embedded C/C++, parse incoming G-code, and translate it into smooth motion and reliable temperature control while guarding against every fault scenario a printer can face. Here is the scope in practical terms: • Motion: drive multiple stepper axes with proper acceleration/deceleration, junction deviation, and micro-stepping using the two Trinamic driver families. • Temperature: read NTC thermistors, run a well-tuned PID loop for hotend and bed, manage cooling fans, and shut everything down on thermal runaway. • Safety &...

I am rapidly up-skilling in CUDA C++ and want an experienced mentor who can walk me through the real-world use of the core foundational libraries—Thrust, CUB, and libcudacxx. My main need is to see clean, well-explained example implementations and concrete use cases rather than abstract theory. Here is what I have in mind: • Short, focused code samples that highlight best-practice patterns in each library (device vectors, reductions, custom kernels, cooperative groups, etc.). • Step-by-step explanations of how these examples map to GPU execution, memory hierarchies, and performance considerations. • Guidance on how to slot each snippet into an existing CMake-based project so I can experiment immediately. I already have a CUDA 12.x toolchain set up with Visual ...

I’m wrapping up the hardware side of a 3.5 kW single-phase on-grid inverter I’m building for my own use and now need well-structured C firmware to bring it to life. The goal is solid, standards-minded code that will: • keep the inverter phase-locked to the utility grid (grid synchronization), • sample and report key electrical parameters in real time (power monitoring), and • trigger a fast, orderly shutdown whenever limits are exceeded or the grid disappears (safety shutdown). I will share the full microcontroller pin-map, schematic details, and any manufacturer SDKs I already have. You’re free to work with bare-metal C or leverage vendor libraries as long as the final build remains portable and easy for me to maintain. Clear comments, interrupt-...

I’m running an iPhone 13 on iOS 16.5.1 with the rootless Dopamine jailbreak and I need a custom tweak that makes Safari believe it is receiving a live camera feed while, in reality, it is streaming a pre-recorded video. Existing “virtual camera” solutions fail with Safari/WebRTC, so this must be built specifically for that environment. Primary goal • Whenever a website opened in Safari asks for camera permission, it should receive a continuous MP4 video I have stored on-device—not the physical rear or front camera feed. There is no need for overlays or live-feed switching; the real camera should be completely bypassed. Configuration • I’d like to point the tweak to the video of my selection in the camera roll or via a static file path (e.g., th...

My PEL-600 channel-letter bending machine in Malmö has ground to a halt because the controller software now refuses to run, citing a “service-life / authorization” limitation. I need a CNC programmer who can visit the shop, get hands-on with the machine, and bring it back to full production. You will be looking at a Windows-based control PC that drives proprietary motion cards and servos. The job starts with classic software troubleshooting—locating exactly where the license or runtime lock sits—then moves into custom software work so the machine boots cleanly every time and stays reliable. Whether this calls for patching the existing executable, rewriting key routines, or building a lightweight replacement interface in C++/C#, I’m open, as long as the G...
