I’m putting together a compact desk ornament that spins on command, and I need a complete PCB solution to drive the rotation reliably. The ornament will only move when a small switch is flipped—no sensors, no remotes, just simple manual control feeding a quiet motor. Main Features: • main power source is 5V from USB to DC power jack connected to board via JST-PH cable 2pin socket. • 3.7V 800mAH Lithium chargeable battery as backup power source, connected via JST-XH cable. • 3-way SPDT switch(on, off, timer) connected to the PCB via a JST-XH cable. • 3V DC motor with peak current around 3A, connected to board via JST-PH(2pin) • 2 mounting points (M3 size to allow M2.5 bolts) Here’s what I’m after: • Schematic and PCB layout for a ...

I already have a working PCB built around an Xsens MTi-630 IMU and an NXP MKV56 microcontroller. What I need now is a technician who can revise the existing firmware so the remote camera head delivers rock-solid motion compensation on set. Your task is to design and embed a custom sensor-fusion routine that blends gyro, accelerometer, and magnetometer data from the MTi-630, then feed that fused orientation into the motor-control loop over CANopen. I’m aiming for a balanced mix of speed and accuracy so operators never feel lag yet still enjoy drift-free performance during long takes. You will be starting from my current codebase (MCUXpresso / NXP SDK), which already handles basic hardware abstraction and CANopen messaging. The focus is on: • Writing or adapting a quaterni...

Need software enginner who will help for STM32 Programming Skills required : 1. C Programming and debugging 2. should know Free RTOS Concepts 3. Shall be able to prepare Design using state flow diagram and flow charts 4. shall be able to write the test cases to test the project in excel sheet TASKS are : 1. make PWM OUT Woking and control wheels 2.

Project Description: I’m building a small ROS 2–ready mobile robot platform aimed at undergraduate and MSc robotics education. The mechanical chassis and system architecture are already defined, and I’m now looking for an experienced STM32 firmware developer to implement the motor controller firmware. This is not a vague research project — a detailed firmware specification, protocol definition, and safety model already exist. The task is to implement them cleanly and robustly. Scope of Work: You will develop firmware for an STM32-based motor controller with the following characteristics: Core functionality: - Closed-loop wheel speed control (2 motors) - Quadrature encoder input (3.3V TTL) - PWM + DIR motor driver outputs (one per motor) - Deterministic control ...

I’m building an industrial-grade control panel that runs entirely on an Arduino and drives motors through fully programmed sequences—no manual switches or computer dashboards, just reliable, repeatable automation once the sketch is flashed. Here’s what I need: • An Arduino sketch that steps each motor through the required sequence, including start-up delays, speed changes, direction (when applicable), and safe shut-down logic. • A wiring diagram that shows every connection from the Arduino pins to motor drivers, relays, fuses, and any protection or feedback components you feel are essential for industrial duty. • Parts list with exact component ratings so I can source hardware that withstands continuous operation. • Brief commissioning guid...
