The board must interface with: . 1x air pressure sensor · 2x 3‑digit seven‑segment displays · 1x 7‑digit seven‑segment display · Oxygen sensor · 3x 12V solenoid valves – controlled via on‑board MOSFETs · 1x flowmeter – pulse output, interrupt input · 1x 10‑key touch keypad · 2x I2C LCD displays (16×2) · 1x water level sensor...

I already built the user interface in SquareLine Studio for an Elecrow 7" CrowPanel (ESP32-S3). The layout consists of four full-screen background images with four transparent touch buttons placed on top. Pressing a button should simply toggle a corresponding light by driving one of the three external relays wired to the CrowPanel’s GPIOs; touching it again turns the same light back off. What I still need is the firmware that ties everything together: • Import the SquareLine-generated LVGL project, read the touch events, and link each of the four on-screen buttons to its relay output. • Drive the relays through ESP32 GPIOs with proper debouncing and visual feedback on the button (e.g. highlighted state while the light is ON). • Provide a clean PlatformIO o...

I need a standalone Data plugin DLL that plugs straight into Amibroker and streams Sharekhan market data in real time into Amibroker , while also back-filling the full historical record—tick-by-tick, 1-minute, daily and monthly—for every symbol I subscribe to. Only one broker feed will be active at any moment, and for this first release that feed is Sharekhan; however, the code structure should be clean enough that I can wire in for other DATA API Vendors / Brokers later without a rewrite. Core requirements • Real-time stream: millisecond-level updates pushed from the Sharekhan Data API with automatic reconnect and gap filling. • Historical loader: on initial sync the plugin must pull tick, minute, daily and monthly bars until Amibroker’s database is fully...

I’m looking for a clean, lightweight Android application whose sole purpose right now is to control my ESP32-based hardware. The interaction must be through on-screen buttons only—no sliders or voice commands at this stage. Tapping a button on the phone should send an immediate command to the ESP32 so the device reacts with minimal latency. I already have the firmware running on the board; what I need from you is the Android side: screen layout, reliable connection logic, and simple feedback to confirm each command was sent. I’m open to whichever transport layer you feel is most robust with the ESP32 (classic Bluetooth, BLE, Wi-Fi sockets, HTTP requests, etc.); just outline your choice and why. Data monitoring and alert notifications aren’t required now but I&rsq...

I already have a custom carrier board laid out, but the power section needs a quick revision—the existing regulator must be swapped for a different power regulator before we move to assembly. The current design is finalized, but one power IC is out of stock and needs to be replaced with an available alternative. I’ll provide the current schematic, layout files (Altium/KiCad), and the BOM; your task is to integrate the new regulator, verify all power-integrity considerations, update the PCB documents, and get the board ready for manufacturing again. Once the hardware files are final, I’ll need help bringing the board up in software. Specifically, I’m looking for boot-ready firmware plus the low-level drivers required for the OS I’ll be installing in-house. The...

I need a developer who can wire my prop-firm account into their public API and then build an automated trading bot that runs on top of that connection. You will receive the API key, endpoint documentation, and my strategy logic; your job is to translate that into clean, dependable code that places and manages trades hands-free. Because this will ultimately control real capital, stability, reconnection logic, and proper error handling are essential. I also want simple configuration files so I can tweak risk parameters without touching the source. Once everything is in place, a brief walkthrough video or live call showing the bot executing a test sequence on a demo account will serve as acceptance. Deliverables: • Fully functioning API integration module • Automated tradi...

I’m looking for a fully-automated trading bot that operates on Polymarket and follows a clear trend-following strategy. The core requirement is that once the bot is live it can open, manage, and close positions without manual intervention, reacting to price trends in real time. You’re free to choose the programming language and tech stack, provided the final solution is reliable and easy for me to run on a VPS. A straightforward configuration file or dashboard that lets me adjust risk parameters and market filters would be ideal. Robust error handling and basic logging are a must so I can monitor performance and diagnose issues quickly. Because I need this finished within a month, I’ll appreciate a concise development roadmap, quick progress check-ins, and well-commente...

I’m building a high-speed communication interface on an STM32-based board and need production-ready firmware written in C/C++. The microcontroller is an ARM Cortex-M series device, and the single most important goal is to move packets through the interface as quickly and reliably as possible—latency can be modest as long as overall data throughput remains very high. You will design and code the full communication stack, configure the peripheral clocks, DMA, interrupts, and buffering strategy, then expose a clean API that my application layer can call from RTOS or bare-metal. Low-level register work is fine, but you’re equally welcome to leverage STM32 HAL/LL or CubeMX if that accelerates development; the final code must compile under STM32CubeIDE or GCC-based Makefiles...

I’m creating a complete historical total-conversion mod for Mount & Blade: Warband and need an experienced modder who can take the concept from rough notes to a fully playable release. The goal is to replace every native asset that matters—world map, factions, troops, dialogs, equipment, music and UI—so the game feels as though it was originally set in the chosen historical period. You should already be comfortable with the Warband Module System (Python), OpenBRF for mesh and texture work, and the typical companion tools such as Morgh’s Editor or Blender when custom models are required. If you have experience scripting advanced features like diplomacy, formation AI or custom settlement mechanics, that will help the mod stand out. Deliverables • A co...

I have several ongoing initiatives that each require their own AI agent—some conversational, others focused on data extraction or decision support. I need someone who can take an idea, choose an appropriate framework (for example, Python with LangChain or Rasa for chat, TensorFlow or PyTorch for analysis-heavy tasks), and turn that into a production-ready microservice or packaged module. Typical flow • Review the project brief with me and translate objectives into agent capabilities • Propose the tech stack and model choice, clearly explaining trade-offs • Build, test, and fine-tune the agent, then expose it through a clean API or SDK • Hand over clear documentation and lightweight maintenance scripts (Docker or similar) Because each project differs, modul...

I want a production-grade, fully automated trading system that sells NIFTY options through the Zerodha API, written entirely in Python. At the start of every session I will manually type a single NIFTY Futures price—this is the fixed “Reference Line.” The bot must store that value, keep it unchanged for the whole run, and switch side logic only when I restart or deliberately reset the strategy. Live futures above the Reference Line put the strategy in BUY SIDE mode; below it switches to SELL SIDE mode. Rather than choosing strikes by distance, the script must pick the option contract whose premium matches a target price that I will supply. Orders, position sizing and exits have to follow that premium-based selection on whatever side is active. Data comes only from the Z...

I have a finalist for a low-latency software-developer role and want an experienced engineer to run a focused technical assessment. The candidate works daily with C++ and Python and claims deep exposure to network optimization, real-time data processing and high-frequency trading systems, so the interview needs to probe exactly those areas. You would design and host a live, screen-sharing session that dives into lock-free C++ patterns, kernel-bypass networking, profiling tools, latency budgeting, and Python-based data pipelines. I will forward the résumé and any code samples in advance; you prepare the questions, run the interview (Zoom, Meet or similar) and challenge the candidate with practical problem-solving rather than trivia. Deliverables: • 45-60 min techn...

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 ...

Context and constraints This firmware is for security research, not production ...

A retro 16-bit horror adventure is ready for its code backbone. The pixel art, environments, and audio are already well underway; what remains is the entire gameplay logic. Scope • Character controls: smooth 2-D movement, context-sensitive interaction prompts, and controller/keyboard support. • AI behavior: unpredictable enemy pathing, simple state-machine–driven stealth detection, and basic NPC scripting. • Inventory system: pick-ups, limited slots, item-use events, and save/load persistence. Engine & Language Unity with C#, Unreal with C++, or Godot with GDScript all work for me—choose the stack you feel most confident with and outline why it suits the project. Workflow 1. Set up a clean, documented project template. 2. Implement core syste...

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.
