The Flashing LED Globe DIY Kit adopts a PCB three-dimensional structure design combined with motor rotation and LED light flashing circuit.Built-in 3 music atautomatic looping playing mode if turn ON music play switch. Also can adjusting the rotational speed. It is a very interesting DIY electronic kit which enables users to learn soldering skills.


Feature:

【ROTATING PLANETS】The lights on the elliptical PCB board of the DIY soldering kit illuminate in turns, creating a rotating effect akin to small planets, which is quite captivating. The exquisite design of the white waterfall light, with its interplay of light and shadow, seems to narrate a fantastical journey through the universe. Paired with such a unique lighting fixture, it enhances the indoor decor ambiance, allowing one to experience the mystery and beauty of the cosmos.


【BRIGHTNESS ADJUSTABLE】DIY soldering practice kit comes with a circular PCB board equipped with a potentiometer, allowing you to adjust the brightness of the blue LED lights. You can customize the lighting to a comfortable level according to your preference. This is a fun and practical project, suitable for soldering enthusiasts to practice their soldering skills and understand circuit principles.


【SPEED SWITCH】The base of the DIY globe kit is equipped with a motor, allowing the globe to rotate 360 degrees, adding a futuristic touch to it. By controlling the motor switch, you can observe various aspects of the kit, as if being immersed in the universe. Whether as a learning tool or a decorative piece, this rotating globe is a creative and enjoyable choice.


【BUILT-IN THREE MUSICS】The planetary kit comes with three sci-fi-inspired music tracks, allowing you to immerse yourself in the wonderful spectacle of planets orbiting the Earth. The music playback adds dynamism and emotion to this planetary model, making observations more vivid. Equipped with separate control switches, you can freely choose to turn the music on or off, making the experience more personalized.

Install 1pc SMD Components SOP-8KT148A Music IC at U1.

Please verify and confrm the installation direction of KT148A.

There is a dot mark on one end of the IC and there is a gap mark on PCB silk screen where the IC can place on. These two marks are corresponding to each other and are used to specify the installation direction of the IC.


Randomly Choose a Pad on the PCB, and Then Melt the Solder
