I’m building a smart irrigation setup that links a Raspberry Pi edge server with several ESP32 nodes in the field. Each ESP32 gathers data from soil-moisture probes, compact weather boards (temperature, humidity, barometric pressure), and inline flow meters, then reports everything wirelessly to the Pi for processing. Here’s what I need from you: • Python (Raspberry Pi) and MicroPython/C++ (ESP32) code that ingests the raw sensor streams, pushes them through an on-device model, and decides—within seconds—whether to start or stop the main pump and which solenoid valves to open. • An ML pipeline: training notebooks, a lightweight model (TensorFlow Lite or similar) and the inference wrapper that runs locally. The model mu...

...MediaPipe or OpenCV will handle hand-tracking and gesture recognition. On the hardware side the code must remain portable to Raspberry Pi OS and Arduino-based prototypes, so a clean Python or Node.js bridge is essential. Here’s what I’d like you to deliver: • A Unity scene that compiles on Android and iOS, wired for AR Foundation with robust user interaction logic (tap, pinch, swipe, custom gestures). • Integration of MediaPipe/OpenCV scripts so gestures trigger in-app events with minimal latency. • A small library of optimized 3D models (Blender or Maya) that match the style guide I’ll share. • Clear setup instructions so I can rebuild and deploy on mobile and Raspberry Pi boards. I’m concentrating on AR/XR...

...script that will run on a Raspberry Pi 5 and do the following: • Watch a single GPIO input line for the HIGH digital signal coming from my Sony camera’s built-in AI output. • As soon as that digital signal is detected, drive a separate GPIO output that energises a small 5 V solenoid for five seconds, then automatically switch it off. • Debounce or otherwise ignore any further triggers until the five-second period is complete. The camera only provides a digital signal, so no protocol parsing is required—plain HIGH/LOW logic on the GPIO pin is all I need. The trigger itself must use the Pi’s native GPIO header rather than USB or networking. I haven’t fixed the exact GPIO numbers yet; feel free to suggest sensible defaults that wo...

...together a compact cyberdeck and need a clean, minimalist enclosure designed specifically for plastic fabrication. The aesthetic I have in mind is smooth, understated, and free of visual clutter—sharp edges only where function demands them, with generous radius fillets elsewhere so the shell feels as seamless as possible. The case will house a mainboard roughly the size of a small laptop, a Raspberry Pi, and a slim battery pack. I’ll provide the exact board outline, port locations, and cooling requirements as soon as we kick off; your task is to wrap that hardware in a practical shell that can be produced on an FDM printer now and, if all goes well, adapted for injection moulding later. Key points I need you to hit • Plastic-friendly wall thicknesses...

...runs on a Raspberry Pi 5 and identifies plant-leaf diseases in real time from the Pi camera. The same core model must also accept still-image uploads. All three disease categories—Fungal, Bacterial and Viral—have to be recognised with reliable accuracy. The user interface will be a Django web app. Within that app I want three role levels—Admin, Standard user and Guest—each with appropriate permissions for running detections, reviewing results and managing data. Please structure the code so that REST endpoints are cleanly separated; this will let me expose the following Android-ready APIs later on: live-video analysis, image-file analysis and retrieval of disease-history logs. Deliverables • Python inference engine (TensorFlow/PyTorch...

I need an enclosure modelled for a Raspberry Pi 4 B that will be printed first in PLA and later in PETG or ABS. The design has three fixed requirements: • Only the USB-C power port and the Ethernet jack are exposed; every other connector stays hidden inside. • A 5-inch touchscreen sits flush on the pi connecting to HDMI and GPIO headers underneath. I will supply product links, datasheets, and photos so you can match the exact footprint and height. The case should go up to the screen edge so it is all in one case for dust protection in my garage. • Heat must escape through slotted vents—your layout and pattern choice are up to you as long as they look clean and print reliably. No internal standoffs, screw bosses, or mounting posts are needed; ...

I want to turn my stock WowWee MiP into a fully-independent companion with far more capability than the original phone-controlled toy. The big push is to give it functional robotic arms—servo-driven, proportional, and strong enough to perform simple pick-and-place demos—while keeping the self-balancing chassis intact. To drive everything, I need an internal “brain” (Raspberry Pi, ESP32, or another MCU you’re comfortable with) that can: • run onboard code without any phone connection • store multiple programs in flash so I can swap behaviors on the fly • process a forward-facing camera for navigation and object tracking • handle voice-command triggers and speak back in character using a small speaker For interacti...

...break-ins and sending instant alerts. The core idea is a mobile unit that patrols designated zones, recognises unauthorised entry, and pushes real-time notifications (sound, SMS, or app-based) to my phone while triggering audible deterrents on-site. Here’s the shape of the work: • System architecture: advise on the right combination of sensors (camera, PIR, ultrasonic, mic), onboard processing (Raspberry Pi, Jetson, or similar), and wireless protocols so the robot can run edge-based computer-vision without relying on the cloud. • Detection pipeline: develop or integrate a lightweight model—OpenCV or TensorFlow-Lite is fine—that reliably flags human intrusion in low-light and daylight conditions, minimising false positives from pets. •...

...sensor on a Raspberry Pi. I already have the broad concept sketched out; what I need is a partner who can take it from idea to a working, desk-tested prototype. Hardware setup, software development, and full PalmSecure integration are all in scope. That means choosing the right Pi model, wiring the PalmSecure unit and any relays/LED indicators, and making sure the power budget is solid. On the software side I’m leaning toward Python or C++ on Raspberry Pi OS, but I’m open as long as the PalmSecure SDK runs reliably on ARM. The application must handle: • User authentication via palm-vein templates • Secure data storage and quick retrieval of templates and event logs • Real-time system monitoring and reporting (attempt co...

...visual identity and need a designer who can translate the stories behind each name into clean, versatile logo art. “Have your say” should feel like a quiet refuge: the warmth of Hygge, a calming corner where someone writes their thoughts in a journal or colours an intricate page. Think peaceful scenes rather than obvious pens or notebooks, and keep your palette inside teal/aqua, mustard yellow, raspberry, moss green, or indigo. The end result should reassure the viewer that their voice will be heard and held in a safe, natural space. “True North Strong” must shout Canada at a glance. Picture a rugged lumberjack, one boot planted on a log and a Canadian flag resting on his shoulder, with subtle nods to pine, lakes, stars, or tundra in the background. ...

I need a seasoned PCB designer located in Pakistan who can take a concept right through to production-ready files. The boards you create must interface reliably with Arduino, Raspberry Pi, and FPGA modules, so familiarity with their pinouts, signalling levels, and power budgets is essential. You’ll start by translating my functional requirements into clear schematics, then handle the full PCB layout, component selection, and DFM checks. I expect well-organised source files plus manufacturing outputs—Gerbers, drill files, pick-and-place, and an accurate BOM—with every revision traceable. If you prefer Altium, KiCad, Eagle, or OrCAD that’s fine; just let me know which environment you’ll use so I can open the files on my end. Because these boa...

I am looking for someone that can write some software either for the Raspberry Pi or an ESP32 that is a SIP client that will register with a remote Asterisk server and wait for telephone calls. When a call is received the software will answer the call then hang up. If the callers number is in a list of valid numbers the software then activates a GPIO line, otherwise it ignores the call. It then goes back to waiting for a call. If you choose to write for the Pi it will be running with the SD card in readonly mode so it will have to store any variables in RAM. The list of valid phone numbers will be downloaded from a remote API - just a simple RESTful JSON client with a token for authentication over a secure (https) link. The software should refresh the list once every...

I have a working furnace test-rig with a Raspberry Pi, an IR camera pointed at the molten metal pool, and a stepper motor that adjusts the power input. What I need now is a clean, reliable Python program that closes the loop between size of the molten metal zone and stepper motor control. The flow is straightforward: the camera streams infrared frames, the script tracks the pool width in real time, and the stepper motor turns to raise or lower power so the pool stays within a target size. All components are already wired and bench-tested; you can SSH into the Pi as soon as the project begins. Key features the code must ship with: • Real-time monitoring of the pool size (OpenCV or a comparable library is fine) • Auto-calibration routine that maps the wi...

...by an image classification and object detection pipeline that identifies weapons and potentially dangerous objects, such as firearms or other threatening items, directly from video frames. By fusing behavioral cues with object-level visual evidence, the system achieves more reliable and context-aware threat detection, significantly reducing false positives. All processing is implemented on a Raspberry Pi–based embedded hardware architecture, integrating a camera module, onboard computation, and peripheral communication units. Once an abnormal action or threatening object is detected, the system flags the individual of interest, tracks their position, and triggers predefined safety responses such as real-time alerts, visual markers, alarms, or secure communication wit...
