Motivation

The project was inspired by the Vesak festival, a significant religious event commemorating the birth, enlightenment, and passing of Lord Buddha. Having witnessed light displays during Vesak since childhood, I spent six months in research and development to fulfill a long-term dream of creating a personal version.

How It Works

The display utilizes WS2812B RGB LEDs, which are individually programmable. The system architecture involves:

• WLED Firmware: Burned onto an ESP32 C3 Super Mini to control the sequence of the LEDs.
• Xlights Software: Used to design various lighting patterns.
• Falcon Player: Runs on a Raspberry Pi Zero 2 W to store patterns and connect wirelessly to the WLED firmware on the ESP32 to run them.

Components

Hardware

• WS2812B-V5/W LEDs
• ESP32 C3 Super Mini
• Raspberry Pi Zero 2 W

Software and Services

• Xlights and Falcon Player
• WLED (including the native mobile app)
• EasyEDA and Autodesk Fusion 360

Prototyping and Development

• Initial Prototype: Started with 8mm diameter WS2812 LEDs attached to a laser-cut flex board.

• Iterative Improvement: Moved to surface-mounted LED strips to reduce wiring complexity.

• Final Version: The creator designed a custom PCB with individual surface-mounted WS2812B LEDs. Due to the complex, circular copper routes, Autodesk Fusion 360 was used for the routing design, while EasyEDA was used for the schematics & PCB.

Outcome

The final result is an assembled PCB that displays light patterns, often used in conjunction with religious imagery, such as the Birth of Prince Siddhartha.
