Description
🌈 "HAPPINESS" 3D LED Sign with ESP32 and WLED
A challenging yet rewarding decorative lighting project, perfect for experienced makers looking for a unique, fully customizable piece of wall art.
This large 3D sign spelling "HAPPINESS" is designed to be printed in separate, modular pieces. This approach allows for a clean wiring process and easy access to all electronic components. The lighting is driven by addressable LEDs controlled by WLED, offering endless, dynamic light effects.
✨ Key Features
- Modular Design: Each letter is printed separately and then glued together, ensuring perfect alignment and structural integrity.
- Removable Cover: The top section of each letter is removable, simplifying LED installation and any future maintenance.
- Advanced Control: Utilizes an ESP32 (specifically the ESP32-C3 model) running WLED firmware for complete Wi-Fi control over all lighting effects.
- Integrated Cable Management: Built-in holes and channels allow for seamless and hidden cable routing between the letters.
⚙️ Electronics and Materials
| Component | Specifications | Notes |
|---|---|---|
| Microcontroller | TENSTAR ROBOT ESP32-C3 | Recommended for its small form factor and Wi-Fi connectivity. |
| LEDs | WS2812B 5050 - 60 LEDs/meter | For dense and bright illumination. |
| Total LED Length | Approx. 6 meters (about 20 ft) | Ensure you size your power supply correctly (≥2A at 5V). |
| Optional (Shifter) | SN74AHCT125N | Recommended to shift the data signal voltage (3.3V from ESP32 to 5V for the LEDs) for improved reliability. |
| 3D Print Material | PLA/PETG in various colors | Thin walls are suggested for light diffusion. Consider opaque colors. |
