How to play: Hold down the release button, insert the spinning top, then release the button to activate the switch and set the top spinning at high speed. Press the release button again to start the battle!

(Note: Be sure to release the spinning top before turning off the switch.)

Bill of Materials:

1. M2.5×6 half-round head machine screws ×7;

2. 604ZZ bearing (size: 4×12×4) ×1;

3. SS12F15VG6 toggle switch ×1;

4. 14500 lithium battery ×1;

5. TP4056 charge/discharge module ×1;

6. Miniature 130 motor ×1;

7. One rubber band.

Note: You can search for and purchase the screws and bearings yourself; for the other components, please download the documentation for the corresponding links (the linked version includes wiring, so you can assemble it directly. If you have a soldering iron, you can also purchase parts of the same size and specifications from Taobao).

Assembly instructions for the launcher:

1. Insert the small gear onto the motor shaft—this may require some force, as it needs to be snugly fitted. Make sure the internal stop is fully engaged.

2. Connect all components using wires. You can measure the wire lengths by pre-assembling the parts into the housing first. (Note: If you’re soldering the motor wires, pay attention to the orientation to avoid interference with the cover.)

3. Install the power unit into the housing;

4. Assemble the release mechanism: first install the linkage, then slip the fork over the rubber band and attach it, followed by the button. After installation, press down on the fork and test whether the button returns smoothly. If the rubber band is too long, trim it and tie it securely until the fit is just right.

5. Install the bearing onto the large gear, then fit the gear into the housing. The gear should turn smoothly; if it feels stuck, check whether the small gear is properly seated.

6. Install the switch paddle.

7. Attach the top cover and tighten the screws to complete the assembly.

Simply glue the two halves of the spinning top together. Remember to remove any supports on the main body!
