Holographic Fan Display Controller Kit — Arduino Mega + WS2812B LED Strip

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

Imagine crafting a floating 3D display that turns thin air into a canvas for your own pixel art, text, or animations — all driven by an Arduino Mega you programmed yourself. This kit puts the core of a commercial holographic fan right on your workbench, using a high-speed BLDC motor and a 144 LED/m strip synced by a Hall effect sensor. Perfect for engineering final-year projects, Smart India Hackathon demos, or ambitious maker installations, you’ll move from concept to running display in a single weekend.

What You'll Build

You’ll assemble a spinning LED arm that projects full-colour, 360-degree visible images in the air — from a clock interface to a company logo to animated characters. The Arduino Mega handles precise column timing based on RPM feedback, so every frame stays crisp even as the motor spins at over 2000 RPM. The finished display sits inside an enclosed box with its own 5V 5A power supply, ready to showcase anywhere.

What You'll Learn

• Writing interrupt‑driven code to synchronise LED column updates with a Hall‑effect tachometer signal
• Calibrating a brushless DC motor and electronic speed controller for stable RPM under varying load
• Designing a robust power distribution scheme that handles the high‑current demands of 144 RGB LEDs plus an Arduino Mega
• Using a slip ring to deliver data and power to a rapidly rotating assembly without tangling wires

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is built for final‑year B.Tech ECE/EEE students building their capstone project, makers preparing a compelling demonstration for Smart India Hackathon or a tech‑art installation, and experienced hobbyists ready to push beyond basic Arduino LED projects. If you’ve handled high‑current wiring and interrupt‑based programming before, the holographic fan will test your real‑time systems skills in the most visual way possible.

Built and Backed by Compoden
