San Francisco based engineer needed I'm seeking an expert to create two remote-controlled mecanum-wheel systems for use in a live theatre show to control two moving set pieces. Wheels, motors and parts purchased independently by us. Requirements: - Forward/Backward/Side movement - Speed control - High precision in movements Ideal Skills and Experience: - Experience with robotics and remote control systems - Proficiency in custom remote control design - Strong understanding of mecanum wheel mechanics and movement dynamics - Ability to deliver smooth, precise control Please share relevant past work and ensure you can meet the precision requirement.

Seeking a Software Developer & Electronics Engineer building innovative IoT and embedded systems. Must have experience and sample project regarding Vending machine connected with Raspberry pi through MDB-to-RS232. Please include sample project screenshots or url. Answer one question about attached screenshot. "What do numbers in request mean? What is MDB Interface command to vend approval from Raspberry Pi? If you don't include above reference and answers, your bid will be ignored. Best

Build Mobile Robot Prototype (Motors, Sensors, 3D Printed Enclosure) I’m looking for a freelance engineer to help build a small mobile robot prototype. This is an early-stage, hands-on project. The concept, basic design direction, and initial 3D enclosure files (STL) are already defined. I need support turning this into a working physical prototype. The robot will: - move using a 2-wheel motor setup - detect basic environmental input (proximity/distance) - respond with simple movement and feedback (light/sound) - run structured behavior logic (idle, react, reposition) This is a practical build project, not a research or high-complexity robotics system. Scope of Work Hardware Integration Set up Raspberry Pi (or recommend alternative such as Arduino/ESP32) Integrate: 2x DC ge...

I need one production-ready showcase device built and shipped within 3–4 weeks. This goes directly in front of investors — it must look finished, not prototype. The device: A wall-mounted solar monitor called VEO. Round display showing live data. 24-LED NeoPixel ring glowing green (healthy) or red (fault). Compact enclosure. Power on → demo starts. No desktop, no setup. Your job: • Mount Pi Zero 2W, round display, and NeoPixel ring into a clean enclosure • Wire NeoPixel ring concentrically around the display • Configure Pi to boot headless directly into existing Python app (already written) • Ensure Wi-Fi auto-connects on boot Enclosure: 3D printed, acrylic, or machined — your choice. No exposed wiring. Display flush with front face. LED ring ...

I am bringing together three work-streams—hardware, machine-learning and front-end—to create a compact Near-Infrared (NIR) analysis unit based on a Raspberry Pi. 1) NIR Processing PCB I already have a Pi-based prototype on a breadboard; now I need a production-ready PCB that hosts the NIR sensor, analogue front end, ADC, power management and the Pi connector. You will provide the KiCad (or Altium) schematic, layout, BOM and Gerber files, then iterate with me until the board is ready for fabrication and assembly. 2) AI Training Once raw spectra reach the Pi, I want an end-to-end training pipeline that turns them into actionable insights. Expect to clean the data, design a model in Python (TensorFlow/PyTorch), and train it so future samples are processed locally on the Pi...

I need the full control system finished and polished. I have a Wittern 3589 vending machine already wired to a Raspberry Pi through an MDB interface. Core functions I still need implemented are: • Daily item limits – each employee may vend up to five items per day, with the count resetting at midnight. • Employee FOB management – the system must store up to 50 active FOBs. I should be able to add, disable, or swap a FOB for a new employee instantly from within the app. • Day-off scheduling – with a tap I can block or unblock the entire machine for specific calendar days (holidays, inventory, etc.). The interface must be available both as a mobile and a web app. All employee changes will be handled exclusively through these apps, not on the Pi itself. Rea...
