1. Introduction
The MiOYOOW DIY Engine Gear LED Light Kit (Model GY21615-1) is an educational electronic soldering project designed to simulate the dynamic movement of gears within an engine using 24 integrated LED lights. This kit offers a hands-on learning experience in basic electronics, mechanical principles, and soldering techniques, making it suitable for STEM education and hobbyists. Upon completion, it functions as an interactive desk ornament with multiple lighting effects.
2. Safety Information
- Adult Supervision: This kit involves soldering and small electronic components. Adult supervision is recommended for younger users.
- Soldering Safety: Always use soldering irons in a well-ventilated area. Avoid touching the hot tip of the soldering iron. Wear appropriate eye protection.
- Component Handling: Handle electronic components carefully. Some components are sensitive to static electricity.
- Power Source: Use only the specified DC power source. Do not connect to incorrect voltage or current.
- Small Parts: Keep small components away from young children to prevent choking hazards.

4. Setup and Assembly
Follow these steps carefully to assemble your DIY Engine Gear LED Light Kit. Refer to the included paper manual for detailed diagrams and component identification.
- Component Identification: Before starting, identify all components using the provided paper manual. Organize them to ensure easy access during assembly.
- Soldering Preparation: Prepare your soldering station. Ensure your soldering iron is heated to the appropriate temperature and you have solder wire and desoldering braid/pump readily available.
- Solder Components: Begin by soldering the smallest components (resistors, diodes) onto the PCB first, followed by larger components (capacitors, ICs, LEDs, switches, DC jack). Pay close attention to component polarity (for diodes, LEDs, and some ICs) and orientation as indicated on the PCB silkscreen. The PCB is clearly labeled for easy connection mapping.
- LED Installation: Install the 24 LEDs according to the PCB markings. Ensure correct polarity for each LED.
- Mechanical Assembly: Once all electronic components are soldered, assemble the mechanical structure using the provided screws and nuts. This typically involves attaching the PCB to the base and securing any protective covers.
- Final Inspection: After assembly, carefully inspect all solder joints for cold joints, bridges, or incorrect component placement. Ensure all connections are secure.

5. Operating Instructions
Once assembled, your Engine Gear LED Light Kit is ready for operation.
- Power Connection: Connect the provided USB power cable to the DC power jack on the kit. Plug the other end into a compatible USB power source (e.g., computer USB port, USB wall adapter).
- Power On: The LED lights should illuminate automatically upon power connection.
- Change Lighting Modes: Locate the switch labeled for lighting modes (typically a push-button or toggle switch). Press or toggle this switch to cycle through the 4 dynamic lighting effects.
- Adjust Flashing Speed: Locate the switch labeled for flashing speed adjustment. Press or toggle this switch to select from the 5 adjustable LED flashing speeds.
