TJ-56-792 LED ballet girl rotating music box DIY kit

This DIY ballet girl rotating musical light kit is a fun soldering training kit designed for electronics beginners and elementary/middle school students in maker classes. The kit consists of individual electronic components, a uniquely shaped PCB in the shape of a ballet dancer, and a transparent acrylic base. Users assemble the circuit by manually inserting and soldering components. Once assembled, the ballet dancer rotates at a constant speed, simultaneously lighting up multi-colored LED sequential lighting with the built-in music box. It serves as an electronics training tool, a desktop decoration, and a creative gift.

Key selling points of the rotating music box:

1. Beginner-friendly soldering, ideal for those with zero electronics experience
Uses standard through-hole components with ample pin spacing, making soldering easy and an excellent teaching tool for beginners in electronics. 1. Learn about basic components such as resistors, capacitors, transistors, and IC chips through hands-on soldering practice. Master the basic techniques of manual soldering and thoroughly understand the basic electrical principles of simple oscillating circuits, sound and light drives, and motor speed control. Suitable for primary and secondary school labor classes and maker club training.
2. Three fun functions in the finished product, integrating sound, light, and rotation
* Multi-color flowing water light: Multiple colored LEDs are distributed on the skirt, which flash in a cycle when powered on, creating a strong sense of light and shadow atmosphere;
* Music box background music: Built-in classic music source chip, automatically playing soft background music upon startup;
* Controllable rotating dance posture: The rotation speed is adjusted by a side knob, and the ballet doll rotates 360° at a uniform speed to the music, just like dancing on stage.

3. High-value transparent shell, exquisite desktop ornament upon completion
The fully transparent acrylic assembly base allows a clear view of the internal circuit board and mechanical structure. The blue ballet PCB design is unique. The finished product can be used as a desk or workstation tech ornament, combining practicality and aesthetics.
