TheDesktop LED Rotating Top Kitis a fascinating educational toy that combines science and fun. Powered bytwo 2032 button batteries, this innovative kit features a unique circuit design that creates mesmerizingLED light patternswhen the top is spun. With aworking voltage of 6Vand acurrent 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 only20g without batteriesand26g with batteries. Its compact dimensions (H: 33mm, Diameter: 54mm) make it easy to store and transport.
