This miniature airplane flashing flowing light DIY kit utilizes a classic 555 timer oscillator + CD4017 counting flowing light circuit design. The entire kit is shaped like a creative airplane, breaking away from the monotonous look of traditional square circuit boards. All components are through-hole, with loose and user-friendly solder joints, allowing even beginners to independently assemble and solder it. When powered on, the multi-color LEDs automatically cycle and flash. It serves as a soldering practice tool for beginners, and also as a fun DIY project for teenagers in science and craft classes. Once soldered, it becomes a complete, illuminated decorative piece.

Core product selling points:
1. Creative airplane-shaped PCB, maximizing fun.
Unlike conventional square training boards, this integrated airplane-shaped circuit board boasts a high-quality finish and can be used directly as a desktop illuminated ornament, significantly enhancing hands-on interest.
2. Self-powered by button batteries, portable with no external power supply.
Onboard dual CR1220 button batteries with built-in toggle switch. Simply insert the batteries to use; no adapter or battery compartment is needed. Simple to operate during training and easy to carry.
3. All through-hole components, beginner-friendly soldering.
Resistors, capacitors, LEDs, and chips are all through-hole components with large solder joint spacing, reducing the risk of short circuits and making soldering beginners easy to learn.
4. Automatic sequential flashing effect, dynamic and intuitive display.
After power-on, the multi-color LEDs on the wings and tail flash sequentially in a sequential flashing pattern, creating a clear and outstanding dynamic lighting effect.
