DIY Acoustic Levitation Ultrasonic Standing Wave Controller Solder Practice Kit

• The TJ-56-551 Ultrasonic Levitation solder practice kit contains all the components needed to levitate small foam balls within standing ultrasonic acoustic waves
• A great gift for those interested in electronics and soldering
• Once assembled, the device requires a 5.5 x 2.1/2.5 (mm) 12V DC power adapter (not included)

This DIY ultrasonic levitation kit is ideal for those learning how to solder and who would like to learn more about electronics. Features: This is a small ultrasonic levitation device that suspends foam balls; The levitator operates at a frequency of 40KHZ in the air, and can capture light objects with a density of 2-3MM in diameter, such as foam balls, ants and other tiny objects that are suspended in the air for a long time, and the main board is slightly heated; The circuit is mainly composed of 1 single-chip microcomputer, 1 driver chip and 2 ultrasonic transmitters; It is mainly used to learn about ultrasonic standing wave levitation. It is suitable for students or DIY electronics enthusiasts to learn ultrasonic levitation standing waves. Product parameters: Power input: DC 12V (0.5-1A) Frequency: 40KHZ Working temperature: -25℃～85℃ Appearance size (finished product): length 44 mm * width 40 mm * height 66 mm Working principle: Ultrasonic standing wave levitation is through the existence of a certain distance between the ultrasonic transmitter and the transmitter (or another transmitter) (called the resonant cavity distance), and the continuous superposition of the transmitted wave and the reflected wave (or another sound wave), and finally forms Standing wave, the acoustic wave force received by the object at the node of the standing wave overcomes the effect of gravity, and finally achieves the effect of suspension.
