Description: This is a mini ultrasonic levitation gadget to levitate foam balls. The device consists of 1 microcontroller, 1 driver chip and 2 ultrasonic probes. Mainly used for students or DIY electronics enthusiasts to learn about ultrasonic standing wave levitation. Does not support the control of levitating objects up and down.Working Principle: ultrasonic standing wave levitation is through the ultrasonic transmitter and reflector (or another transmitter) there is a certain distance (called the resonant cavity distance), the transmitter and reflector (or another sound wave) constantly superimposed on the final formation of standing wave, the standing wave node at the object by the acoustic force to overcome the effect of gravity and ultimately achieve the effect of levitation.Specification: ( Manual)Product Name:Ultrasonic Levitation KitInput Voltage:DC12VInput current:less than 70mALED(red):power indicator lightLED (green): ultrasonic levitation indicatorLevitation time: can be a long time levitation, test 24h levitation stability, the motherboard slightly hot.Dimensions: length 42mm, width 42mm, height 62mm, probe pitch 22mm, manual measurement in errorPacakge included:1 x PCB Circuit Board1 x Components1 x Supporting Manual
