The Desktop LED Rotating Top Kit is a fascinating educational toy that combines science and fun. Powered by two 2032 button batteries, this innovative kit features a unique circuit design that creates mesmerizing LED light patterns when the top is spun. With a working voltage of 6V and a current draw of less than 10mA, it is an engaging way to explore basic electronics and principles of light and motion.
Features
- Dynamic Light Show: When the top spins, a vibration switch activates the circuit, triggering a multivibrator that causes the LEDs to blink in a captivating sequence. Thanks to visual persistence, users will see stunning segmented patterns that come to life with every spin.
- Simple Circuit Mechanics: The kit includes a transistor-based multivibrator circuit, ensuring a smooth and reliable functioning. The two transistors alternate in conducting, creating a continuous cycle of flashing lights that produces illusionary moving shapes.
- Lightweight & Compact: Designed with portability in mind, the top weighs only 20g without batteries and 26g with batteries. Its compact dimensions (H: 33mm, Diameter: 54mm) make it easy to store and transport.
