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 must act on current soil-moisture rea...

I need a concise Python 3 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 default...
The embedded system comprises 2 STM32 boards connected to their own 7 sensors, 1 motor, and 3 relays. Each is connected to a central Raspberry Pi 4 board. The RIGHT STM32 board also has a TFT ST7789 2inch display. The Raspberry Pi has its own 5-inch display (connected via HDMI) and is connected to a battery BMS via UART and controls the main ON/OFF switching of the exoskeleton system driven via a 48V 10A relay. The Raspberry Pi also controls the operation of a 5V air-pump via a relay able to deliver 1.5A. 1. Graphical user interface (GUI) developed for the STM32 to drive the ST7789 display. The detailed requirements for this GUI are presented in Figure 3. 2. GUI developed for the Raspberry Pi display. The detailed requirements for this GUI are the same as for STM32. 3. Software for...

I need help building a working prototype of a small interactive toy. The prototype requires: A pop-up mechanism (using solenoids, springs, and/or small motors). Integration with Raspberry Pi or Arduino for control. Wiring/programming to operate the mechanism. A simple phone/web app to trigger the toy remotely. Requirements: Experience with mechanical design and prototyping. Hands-on skills with Raspberry Pi/Arduino electronics. Must show past project work (photos, CAD, or GitHub). Signed NDA. Deliverable: A working physical prototype (not just design files) that demonstrates the pop-up mechanism controlled by Raspberry Pi/Arduino. Budget: Budget will be discussed based on scope and experience. Please provide: What’s your estimated cost? How did you arrive at that numbe...
I’m putting together a new Raspberry Pi build that will run Ubuntu rather than the standard Raspberry Pi OS. My own experience level is advanced, but I’d like another seasoned set of eyes to speed things up and help polish the system. The job focuses on: • Reviewing my current headless Ubuntu image for best-practice partitioning, bootloader tweaks, and basic hardening • Tracking down and fixing the boot-time warnings that surface in dmesg and journalctl • Suggesting and, where sensible, applying performance optimisations—overclock settings, thermal management, swap behaviour, I/O tweaks • Writing or refining a few clean Bash/Python scripts for unattended updates and off-device backups We’ll work entirely over SSH, so no hardware shipping...
I’m building a small sports POV camera system (VisionCam V1) using a Raspberry Pi Zero 2 W + Raspberry Pi Camera Module 3 Wide (IMX708). I need (A) a simple power/charging board design and (B) a reliable recording service/software for the Pi. Important: My total budget is $600 max for the full scope. Please do not apply if your quote will exceed $600. ⸻ A) Power / Charging Board (Pi Zero 2 W) Goal: Stable power + safe charging for a LiPo, designed for a compact wearable camera. Requirements: • LiPo charging via pogo-pin contacts (no open USB charging port preferred) • Power-path / load sharing so the device can stay on while docked/charging (no reboot) • Stable 5V output to Pi Zero 2 W (with enough current margin) • Battery protection features (basic prote...

The goal is straightforward: as soon as an ESP device is present—whether connected over Wi-Fi or broadcasting in monitor mode could be spotted in hidden places
I need a complete Python application that 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 (...
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 interaction I’m l...
I’m ready to move from concept to working prototype on a home-security robot that focuses solely on emergency response—specifically, detecting 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-L...
I’m building a proof-of-concept access controller that uses Fujitsu’s PalmSecure 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 &bull...
