Product description This is a mini ultrasonic levitation device that can suspend foam balls The device consists of a single chip microcomputer a driver chip and two ultrasonic probes Mainly used for students or DIY electronics enthusiasts to learn about ultrasonic standing wave suspension Controlling the up and down movement of suspended objects is not currently supported Working principle Ultrasonic standing wave suspension is that there is a certain distance between the ultrasonic transmitting end and the reflecting end or another transmitting end called the resonant cavity distance and the transmitted wave and the reflected wave or another acoustic wave are continuously superimposed to form a standing wave The acoustic wave force on the object at the standing wave node overcomes the effect of gravity and finally achieves the effect of suspension Feature Power input DC12VAppearance size 40 40 70mmWeight 26gPackage list CommentDesignatorQuantitySMD STC15W104 SCM S0P81SMD TC4427 chip1SMD AMS1117 chip 5 0V1Plug in electrolytic capacitor 100UF 35V10805 Capacitor 10420805 Resistor 1K10805LED blue1DC2 1 power base1Ultrasonic transmitter T2M2 knurled single pass copper column M2x6 36M2 knurled single pass copper column M2x12 32M2 knurled single pass copper column M2x40 32M2 nut4Foam1PCB boardOne baseplate two launch pads3DC12V power supplyoptional1.
