I have a working Arduino Nano sketch that I now need running on an STM32. The project must be opened, built and flashed entirely inside STM32CubeIDE, so please base every file and configuration step on that toolchain. Key points you will handle • Rewrite the existing sketch for the chosen STM32 device, configuring clocks, GPIO, interrupts and peripherals exactly as needed. • Replace the current Arduino-style calls with HAL-based code generated in CubeMX, keeping the program logic identical. • The original sketch drives an OLED via a third-party library; the same display has to work on STM32, so include whatever open-source driver (U8g2, SSD1306 HAL port, etc.) you feel is most stable. • Alongside the source, provide a short step-by-step guide that shows how t...

I need a complete electronic design for a next-generation health-monitoring smartwatch whose signature element is a high-resolution micro camera mounted flush to the wrist side of the case. That camera will analyse the wearer’s skin to extract deeper, image-based health insights beyond the usual heart-rate and SpO₂ readings. I am open to your proposals on exactly which metrics image processing can reveal, provided they are scientifically sound and can be handled by an embedded processor in real time. Core hardware requirements • High-resolution skin-facing camera, paired with a wearable-class microprocessor powerful enough to process or compress the image stream on-device. • Minimum 16 GB on-board storage for captured data. • Bluetooth for data sync, a vibrant T...

I need a LabVIEW developer to create an inventory system focused on managing our supply chain. The system will specifically handle raw materials and requires real-time tracking capabilities. Key Requirements: - Supply chain management focus - Raw materials inventory - Real-time tracking of inventory levels Ideal Skills and Experience: - Proficiency in LabVIEW - Strong background in supply chain management - Experience with real-time data tracking systems - Ability to design user-friendly interfaces Please provide examples of similar projects completed.

I already have firmware running on an ESP32-based board that includes an RJ45 RS-485/UART port, two analog inputs, several digital I/Os and a small audio stage that automatically answers a SIP/VoIP call and plays audio through an on-board speaker. What I need now is an elegant extension of that code so the same board can also feed data to– and receive commands from – an IoT dashboard app. The new build must keep every existing VoIP feature intact while adding: • A clean, non-blocking interface between the VoIP tasks and the new IoT task set. • Support for both voice playback and tone generation exactly as the current audio path provides. • Reliable sampling of the two AIs along with any DI events, packaged for MQTT/HTTP (whichever you find lighter on re...

I need a clean, well-commented Arduino sketch that drives a small traffic-light prototype using LEDs, push-buttons, and a couple of sensors (e.g., ultrasonic or IR) to regulate flow rather than just cycle through a fixed sequence. The idea is to simulate a real intersection where vehicle presence triggers state changes while manual override buttons allow testing of special conditions. Here’s what I expect: • The code must compile on the current Arduino IDE without extra libraries beyond the standard ones. • Normal operation: red, yellow, and green LEDs follow proper timing, but a vehicle-detection sensor shortens or extends green time to keep traffic moving smoothly. • A pedestrian button interrupts the flow safely, inserting a walk phase before resuming. &bul...

Hi I will share the details with the shortlisted candidates. thanks

I need a working bridge that lets my Meta Quest 3 drive an igus ReBeL robot arm in real time over Wi-Fi. When I wear the headset I want to see and manipulate a 3-D model of the arm; every movement of my controllers or hands should be translated instantly into joint commands so the physical ReBeL mirrors my motion with minimal latency. You will handle both sides of the link: capturing pose data inside the Quest (Unity, Unreal or OpenXR—whichever you prefer) and streaming it wirelessly to the robot, then converting it into the motion commands accepted by the standard ReBeL control interface. A simple UI inside the headset that shows live joint angles and an emergency-stop button is also required. Deliverables: • Headset application for Quest 3 with live arm visualisation and con...

I need an interface connector for carrying sensor readings from Ultrasonic datalogger by Modbus cable RS-485 with a male connector. The PCB interface is to be built with a 6-pin military female connector at one end and printer cable connector at the other end that will be used to connect to a laptop USB port to download the data (Refer to picture attached). Requirements: - Use a female 6 pin military connector (standard adapter) for the military connector and a female print cable connector on the other end, with PCB in between - No custom cable is needed - Ensure compatibility with Modbus protocol - Encapsulate the PCB into aluminium pot or similar for robustness Ideal Skills and Experience: - Expertise in Modbus communication - Experience with military and printer cable connectors - ...

I need a compact, student-friendly iron-repulsion electromagnet that can serve as the centerpiece of a science-fair exhibit. The core requirement is a coil system that pushes a small iron slug or plate away with visibly adjustable force. Key functions to build in: adjustable repulsion strength (a dial or digital control that varies current), wireless or IR remote control for hands-off demos, and a simple safety lock that cuts power instantly if something behaves unexpectedly. Because the device will be handled by middle- and high-school students, absolute electrical safety and clear operating instructions are essential. To make the project reproducible, I will need: • A working prototype capable of at least three distinct strength settings and a demonstrable off-site trigger v...

Computer Vision Developer – Sports Video Analysis (Mobile-Based) Description: We are looking for a skilled computer vision developer to assist with building a prototype system that analyses sports video captured from smartphones. The goal is to detect and track fast-moving objects, identify key events within video footage, and generate structured outputs (e.g. timestamps, event detection, basic classifications). This is an early-stage prototype, so we are looking for someone who can work quickly, think practically, and help shape the technical approach. Key Responsibilities: Develop object detection and tracking models for fast-moving objects (e.g. ball tracking) Process video input from 1–2 mobile camera angles Detect key events (e.g. impacts, direction changes, motion pa...

I am looking to have someone build me a site like this one....

I’m outfitting my scale model airplane with an LED lighting system that switches on automatically whenever someone (or another object) comes close to the aircraft. The motion-sensing method must rely on proximity detection rather than vibration or general movement. already has lights. looking to install motion sensor and on off toggle switch. the touch sensor it currently has is shit and wont stay on for more then 20 sec.

I’m building a small arcade-style attraction made up of six identical stations. Each station will recognise when its hand-held controller is lifted by means of a magnetic sensor—or any other proper kind of sensor —then launch a three-minute countdown. Here is the user flow I need you to realise: 1. Controller is lifted → internal timer starts. 2. An OLED screen at that station immediately shows the remaining time, counting down in real time. 3. When the three minutes expire the screen simply replaces the countdown with a clear “Game Over, move to next zone ” message + a buzzer or light; 4. Once the controller is set back the system must reset itself, ready for the next player. Hardware thoughts so far: magnetic (reed or Hall) sensor to detect li...

I’m building a small desktop-sized robot whose single purpose is to press real-world buttons for me while I’m miles away. The device must execute precise, complex multi-axis motions, then recover to a home position so it can be triggered again. I already know it will live on an ESP32, Arduino or a comparable microcontroller, but I need an experienced partner to turn that concept into a reliable, working prototype. Here’s the vision. A lightweight end-effector reaches out, lines itself up, and delivers a repeatable press with enough force to register the button yet gentle enough not to damage it. Everything is driven from a secure web interface so I can log in from any browser, watch the robot’s status, and command a press in real time—no local Bluetooth tethe...
