Freelance Industrial + Hardware Designer Calibration Wand + Smart Charging Dock

Location: Remote
Engagement: Freelance (Project-based)

We are building a camera calibration system for multi-camera tracking in sports/computer vision applications. As part of this, we need a custom-designed calibration wand that will include precisely spaced marker points (LEDs or passive markers) and a charging/storage cabinet with status LEDs and possible IoT functionality.

This will be a hardware prototyping project involving industrial design, 3D modeling for printing, and basic electronics/IoT.

• Design of a handheld wand with precisely spaced markers (e.g., LED points or reflective balls).
• Lightweight, rigid, and durable design.
• 3D printable STL/STEP files for prototyping.
• Battery-powered with internal wiring for LEDs.
• Should meet calibration accuracy standards (marker spacing tolerance is critical).

• Dock to charge the wand when not in use.
• LED indicators to show battery/charging status.
• Optional: Wi-Fi/Bluetooth integration for remote status checking (battery % etc.).
• Designed to be compact, safe, and manufacturable.

• Industrial Design (especially for ergonomic tools/devices)
• CAD modeling (Fusion 360 / SolidWorks / Rhino)
• 3D printing design best practices (FDM/SLA)
• Basic electronics (battery, LED circuit design, PCB is a bonus)
• IoT prototyping (ESP32/RPi, battery status, LED control, etc.)
• Understanding of camera calibration systems is a big plus

• STL/STEP files for both wand and cabinet
• Renders and exploded views
• Wiring diagrams / component specs
• BOM (Bill of Materials)
• Basic firmware/prototype (if IoT is included)
• Assembly instructions or video (optional)

34 weeks (initial design + revisions + prototype ready)
