The desktop LED spinning top kit is composed of a multivibrator circuit composed of triodes, LEDs, button batteries and vibration switches. The accessories are exquisitely made. The principle is simple and the assembly success rate is high. When the LED gyro is rotated, the vibration switch is powered on, and the multivibrator circuit works to produce LED flickering effects. Due to the phenomenon of visual persistence, there will be a series of patterns, which are vivid and interesting. Great for entertainment, but also for electronics enthusiasts.

Working principle of the circuit:
When the battery is loaded, the vibration switch S1 is disconnected, so the circuit does not work. When the gyroscope is rotated, due to the centrifugal effect, the vibration switch S1 is turned on, and the circuit works. The working principle of the multivibrator circuit is that when the power is turned on, the two transistors Q1 and Q2 will compete to turn on first, but due to the components The difference is that only a certain tube is turned on first. Then the two triodes in the circuit are turned on and off in turn, and the two light-emitting diodes are constantly cyclically emitting light. When the gyroscope is rotated, a straight line will appear on the bright LED. Thousands of lights are staggered, and every two lights are alternately bright, so multiple dotted line-shaped patterns appear.
