Introduction
The Whadda 3D LED Cube Kit (Model WSL8018B) is an educational and creative project designed for enthusiasts of all ages to explore the exciting world of electronics, soldering, and programming. This kit allows you to build a functional 5x5x5 LED cube, featuring 125 bright blue LEDs, which can be programmed to display various light patterns and animations. It serves as an excellent STEM project, providing hands-on experience in assembling electronic components and understanding basic programming concepts.
This manual provides detailed instructions for the assembly, operation, and maintenance of your 3D LED Cube, along with important safety information and troubleshooting tips.
Safety Information
Please read and understand all safety instructions before beginning assembly. Failure to follow these instructions may result in injury or damage to the product.
- Soldering Safety: Soldering involves high temperatures. Always use appropriate personal protective equipment, including safety glasses. Work in a well-ventilated area to avoid inhaling solder fumes. Keep flammable materials away from the soldering iron.
- Electrical Safety: Ensure the power supply is disconnected before making any connections or performing maintenance. Do not touch exposed wires or components when the device is powered on.
- Component Handling: Some electronic components can be sensitive to static electricity. Handle PCBs and integrated circuits by their edges.
- Adult Supervision: This kit is suitable for children and adults. However, adult supervision is recommended for younger users, especially during the soldering process.
- Proper Disposal: Dispose of electronic waste and soldering materials according to local regulations.

Tools Required (Not Included): Soldering iron, solder, wire cutters, wire strippers, small pliers, safety glasses, multimeter (recommended), computer with USB port for programming.
Setup and Assembly
Follow these steps carefully to assemble your 3D LED Cube. It is recommended to watch any official assembly videos provided by Whadda for visual guidance.
- Prepare the LEDs: Carefully bend the leads of each LED to form a 90-degree angle, preparing them for insertion into the cube structure. Ensure consistent lead length for uniform spacing.
- Build LED Layers: Solder 25 LEDs together to form a 5x5 grid. Repeat this process five times to create five identical layers. Pay close attention to LED polarity (anode and cathode).
- Assemble the Cube: Stack the five LED layers, carefully soldering the vertical connections between layers to form the 5x5x5 cube structure. Ensure the cube is straight and stable.
- Prepare the Main PCB: Solder all passive components (resistors, capacitors) and active components (transistors, microcontroller socket if applicable) onto the main PCB according to the silk screen markings and component values.
- Connect the LED Cube to PCB: Carefully align and solder the leads from the assembled LED cube to the designated pads on the main PCB. Double-check all connections for cold solder joints or shorts.
- Mount the PCB: Secure the main PCB to the base using the provided standoffs and screws.
- Initial Power Test: Before programming, connect a compatible 12V power supply (not included) to the power jack. Observe if any LEDs light up or if there are any immediate issues. Disconnect power if any problems are detected.

Operating Instructions
Once assembled, your 3D LED Cube is ready for operation and programming.
- Power On: Connect the 12V DC power adapter (not included) to the power jack on the main PCB. The cube should power on and begin displaying its default pre-programmed patterns.
- Programming:
- Connect the USB programming cable (if provided) from the main PCB to your computer.
- Install the necessary drivers and programming software (e.g., Arduino IDE, specific Whadda software) as instructed in the detailed online manual or quick start guide.
- Upload custom code or modify existing patterns to personalize your LED cube's display. Refer to the Whadda website or community forums for example code and tutorials.
- Pattern Selection: If your kit includes buttons or switches on the PCB, use them to cycle through different pre-programmed patterns or modes.

Maintenance
Proper care will ensure the longevity of your 3D LED Cube.
- Cleaning: Use a soft, dry cloth to gently wipe dust from the cube and PCB. Do not use liquid cleaners or abrasive materials.
- Storage: Store the cube in a dry, dust-free environment away from direct sunlight and extreme temperatures.
- Handling: Avoid dropping or applying excessive force to the cube, as this can damage the delicate LED connections.
Troubleshooting
If you encounter issues with your 3D LED Cube, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No LEDs light up. | No power, incorrect power supply, short circuit, faulty main PCB. | Check power adapter connection and voltage. Inspect PCB for shorts or incorrect component placement. |
| Some LEDs do not light up. | Faulty LED, cold solder joint, incorrect LED polarity, broken trace. | Check solder joints for the affected LEDs. Verify LED polarity. Test individual LEDs if possible. |
| Cube displays erratic patterns or no patterns. | Programming error, loose connection to microcontroller, faulty microcontroller. | Re-upload the default program. Check connections between the cube and the main PCB. Ensure microcontroller is seated correctly. |
| Smoke or burning smell. | Short circuit, incorrect component, reversed polarity. | Immediately disconnect power. Inspect for shorts, reversed components (especially electrolytic capacitors), or incorrect power input. Do not reconnect power until the issue is resolved. |
