I need three distinct road scenarios built in SUMO—urban, highway and rural—each reflecting real-world geometry and traffic behaviour. For every segment you create, the network has to respect the exact length and width I will supply, include the specified number of lanes, apply the correct speed limits and position signboards where noted. The finished work must be delivered as a fully validated SUMO XML network file ready for simulation; no additional conversion on my side should be necessary. Please attach a detailed project proposal that outlines • the tools you will use in the SUMO suite (e.g., NETEDIT, NETGENERATE, additional Python scripts) • how you plan to translate my measurements into the network, handle signboard placement and verify compliance &bu...

I have an ESP32 DevKit V1 (CP2102) already wired to a PZEM-004T V3, an ADS1115 16-bit ADC, one SCT-013-010 CT sensor, and three DS18B20 waterproof probes. With this hardware I need working firmware and a simple cloud-hosted dashboard that can: • Detect and log the compressor state (ON/OFF). • Detect, log, and quantify both the indoor fan status(ON/OFF) as well as fan current or speed. • Read room, inlet, and outlet temperatures. • Calculate hourly power consumption (kWh) and total run-time for the compressor and each fan. • Push every reading over Wi-Fi using pure HTTP requests formatted as JSON. On the front end I want a live web dashboard that combines graphs with raw tables so I can flip between trends and exact values. The visuals should update in n...

I want to create a branded control board that keeps the familiar Arduino UNO R3 footprint yet swaps the ATmega328P for an ESP32. The finished board must: • expose the usual analog inputs, PWM outputs, serial ports and full digital I/O • break-out every pin through sturdy screw terminals instead of header pins • carry an on-board battery cradle for two 18650 cells (3.7 V each) and an integrated 2-cell BMS • arrive pre-flashed so it shows up in the Arduino IDE exactly like a normal UNO-style target Because the unit will be wall-mounted, an ABS enclosure that matches the board outline, standoffs and connector layout is part of the job. I need mechanical files (STEP/STL) alongside the electronics deliverables. Deliverables 1. Schematic, PCB layout and Gerber/ODB files 2...

I’m putting together a pick-and-drop mobile robot inside CoppeliaSim and I need a clean, well-commented Python script that handles two core tasks: • Closed-loop motion control: A PID controller should drive the differential wheels so the robot follows a straight or curved path accurately, with easy access to kp, ki and kd for later retuning. • Vision-based sorting: Using a simulated camera feed, the code must identify basic red, green and blue objects, command the gripper to collect the detected item, then deposit it at a defined drop zone. Everything happens in simulation, so feel free to make full use of CoppeliaSim’s remote-API calls, Python, OpenCV (or a similar vision library), and any helper utilities you find convenient. The scene already contains the robot...

I’m building a proof-of-concept that lets an ultra-low-power board—specifically an ESP32—capture image data and immediately flag early-stage oral cancer. Because the hardware budget is tiny, I need a novel, highly compressed AI architecture that still reaches clinically useful accuracy and inference speed at the edge. The device will ingest live image data from a camera module, run on-device preprocessing, then execute an AI-based model (think pattern-recognition and other machine-learning techniques rather than simple thresholding) fast enough to give instant feedback without off-loading to the cloud. Latency, memory footprint, and power draw must all stay within the ESP32’s limits. If you’re interested, send a detailed project proposal outlining: &bu...

I have a microcontroller-based board that will sit in the field and quietly record temperature readings from one or more digital sensors. Your job is to write the embedded firmware that pulls those readings at set intervals, time-stamps them, and stores everything persistently in a neat, easily downloadable file (CSV or similar). Core needs • Reliable polling of the attached temperature sensors (currently using a standard one-wire digital device, but code should be abstract enough to swap to I²C if required later). • Configurable sample rate—default 1 Hz but changeable over a simple serial menu or compile-time constant. • Local, non-volatile storage on the board’s microSD slot; automatic file rollover when a maximum size is reached so nothing is eve...

I’m taking a brand-new IoT device from idea to working prototype and need an embedded expert who can move smoothly between board-level decisions and low-level code. The scope touches every layer of the stack: • Firmware development • Hardware design • Sensor integration Day-to-day, you’ll be writing tight C/C++ for the MCU, using Python for test harnesses or quick validation scripts, and advising on component choice, schematic capture, and PCB layout. Expect to bring up the first boards, tune power consumption, and create the drivers that let all sensors report reliably to the cloud. Deliverables I’m counting on: 1. Complete schematics, BOM, and ready-for-fab Gerber files. 2. Well-documented firmware (C/C++) with build instructions. 3. Python t...

I have an existing Python-based program built on an established automotive industry framework, and I need to turn its current manual verification and validation steps into a fully automated process. The focus is squarely on software testing: the goal is to generate a clean, well-structured script (or set of scripts) that can exercise the application under realistic conditions, log results, and flag regressions without human intervention. During a short call I will walk you through the codebase, the framework dependencies, and the exact pass/fail criteria we already use in production. From there, you will design and implement the automation logic in Python, wiring it into our CI environment (Git, pytest, or an equivalent runner—whichever you are most comfortable with). Clear, well-co...

I need two simple yet reliable prototype nodes that can sit outdoors, wake up at a configurable interval, pull a register line from a Modbus-compatible soil probe, and push that reading through a Meshtastic link. No commercial polish required—the goal is to prove the data path end-to-end. Scope of work • Recommend and source—or at least specify—a compact board, radio module, and battery pack (AA-powered) suited for outdoor use. I currently have no hardware on hand, so component guidance is essential. • Write Python-based firmware (preferred language) that: – Powers the Modbus interface, retrieves the probe value, and sleeps between cycles to conserve the batteries. – Publishes the reading over Meshtastic in a lightweight JSON or CSV payl...

I need someone to get to the bottom of an annoying issue that shows up whenever I connect an external keyboard and mouse to my Windows-based laptop. The mouse fires off ghost clicks on its own, the pointer stutters, and League of Legends—along with a few other everyday apps—slows to a crawl even though my ping and frame rate look normal. Here’s what I already know: • I swapped in another set of peripherals and the exact same problem sticks around, so it’s not the hardware itself. • The lag is visible outside of League, so the game isn’t the lone culprit. • Windows, chipset, BIOS, graphics, and peripheral drivers are fully up to date. What I’m after is a clean, repeatable fix (or set of fixes) that stops the phantom clicks, rest...

I’m building a small toy that plays a single prerecorded sound. To make this work I need a PCB design built around the OTP voice chip, a LiPo battery with its recharge module, and an on-board micro speaker. A simple momentary push-button should trigger playback; no other activation modes are required. Space is at a premium: the entire populated board, battery, and speaker footprint must fit comfortably within roughly 3 cm × 3 cm x 4 cm. Deliverables • List of components • Connection intructions Please choose components easy to be found in the web, cheap and use as few as possible.
