Create a Full-Motion Holographic Fan Display with Arduino Mega and High-Speed LEDs

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

This kit puts a full-motion holographic fan display in your hands — a spinning arm of addressable LEDs that paints crisp, floating images in thin air. You'll synchronize a BLDC motor's RPM with precisely timed pixel data on a WS2812B strip, using Hall effect feedback and an Arduino Mega 2560. The result is a programmable, mid-air canvas that can show animations, text, or even your own logo, making it a showstopping engineering project for hackathons, exhibitions, or your final-year demo.

What You'll Build

You will assemble and program a rotating LED fan that generates stable, high-resolution POV images visible from all angles. By the end, you'll have a self-contained display unit that you can control via serial commands or pre-loaded frame buffers. It's a fully functional, portable holographic projector that demonstrates mastery of real-time control, motor sync, and LED matrix rendering.

What You'll Learn

• Precise motor speed measurement using a Hall effect sensor and interrupt-driven RPM calculation
• Timing-critical WS2812B LED control to match pixel columns with the fan's angular position
• Buffer-based frame generation for smooth animations without visible tearing
• High-current power distribution design with filtering capacitors to prevent LED flicker under load

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This is an advanced kit built for B.Tech ECE and EEE students in their final year, Smart India Hackathon participants tackling display or AR/VR problems, and hobbyists who have already worked with addressable LEDs and motor control. If you're at an IIT, NIT, VIT, BITS, or similar institution and need a high-impact hardware project that demonstrates real-time embedded systems and creative engineering, this kit gives you everything to go from zero to a spinning holographic display.
