Setup and Assembly Instructions
Follow these steps carefully to assemble your planetary motion kit. Refer to the included paper guide for detailed diagrams.
- Prepare Components: Unpack all components and organize them. Identify the different PCBs (base, globe, ring) and electronic parts.
- Solder LEDs to Globe and Ring PCBs: Carefully solder the blue LEDs onto the designated pads on the globe and ring PCBs. Ensure correct polarity (longer leg to square pad).
- Assemble Base Circuitry: Solder the motor, switches, potentiometer, speaker, and other electronic components (resistors, capacitors, ICs) onto the main base PCB according to the circuit diagram in your paper manual. Pay close attention to component values and orientation.
- Mount Motor: Secure the motor to the base PCB using the provided screws.
- Connect Globe and Ring: Attach the globe PCB to the central shaft and secure the LED ring around it. Ensure electrical connections are made as per the instructions, often involving small springs or wires.
- Assemble Layers: Mount the assembled globe and ring structure onto the base using the standoffs and screws, creating the multi-layered planetary model.
- Final Connections: Connect the USB power cable to the designated power input on the base PCB.

Maintenance
- Cleaning: Use a soft, dry cloth to gently wipe the surface of the kit. Avoid using abrasive cleaners or solvents.
- Storage: Store the kit in a dry, dust-free environment when not in use.
- Component Check: Periodically inspect solder joints for any signs of cracking or corrosion. Re-solder if necessary.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| LEDs do not light up. | Incorrect LED polarity, poor solder joint, faulty LED, no power. | Check LED orientation, inspect and re-solder connections, verify power supply. |
| Motor does not rotate. | Poor motor connection, faulty motor, rotation switch off. | Check motor wiring, ensure rotation switch is on, inspect solder joints. |
| Music does not play. | Music switch off, poor speaker connection, faulty speaker/IC. | Ensure music switch is on, check speaker wiring, inspect solder joints. |
| Brightness adjustment not working. | Faulty potentiometer, poor connection to potentiometer. | Inspect potentiometer wiring and solder joints. |
