This is a small ultrasonic suspension device, which can suspend foam balls; <br/>2. The suspending device 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 small objects that are stably suspended in the air for a long time, and the main board is slightly heated; <br/>3. The circuit mainly consists of one microcontroller, one driver chip, and two ultrasonic emission heads; <br/>4. Simple operation: clamp the small foam ball with tweezers, gently place the foam ball between two ultrasonic probes, and the foam ball will be suspended; <br/>5. Mainly used for learning and understanding ultrasonic standing wave suspension, suitable for students or DIY electronics enthusiasts to learn ultrasonic standing wave suspension.</p><p><strong><span style="font-size:20px">Parameter: </span></strong><br/>Power input: DC5V (0.5-1A) <br/>Frequency: 40KHZ <br/>Working temperature: -25 ℃~85 ℃ <br/>Appearance dimensions (finished product): length 45mm * width 44mm * height 66mm <br/>Working principle: Ultrasonic standing wave suspension is achieved by a certain distance (called resonant cavity distance) between the ultrasonic emission end and the emission end (or another emission end), where the emitted wave and the reflected wave (or another sound wave) continuously overlap to form a standing wave. The sound wave force acting on the object at the standing wave node overcomes gravity and ultimately achieves the effect of suspension. <br/>Play: Clamp the small foam ball with tweezers, gently place the foam ball between the two ultrasonic probes, and the foam ball will be suspended.</p><p><strong><span style="font-size:20px">Package include: </span></strong><br/>Set 1: <br/>DIY loose parts shipping list: <br/>Upper PCB board * 1 <br/>Lower PCB board * 1 <br/>Ultrasonic emission head T * 2 <br/>M2 * 4 screws * 5 <br/>M2 * 7 double copper column * 2 <br/>M2 * 39+3 copper pillar * 2 <br/>M3 * 6 screws * 5 <br/>M3 * 15 double nylon columns * 4 <br/>25V 47UF * 2 <br/>TYPE-C seat * 1 <br/>104 single stone capacitor * 3 <br/>101 ceramic capacitor * 1 <br/>4.7K resistor * 1 <br/>1 ohm resistor * 1 <br/>1K resistor * 1 <br/>10K resistor * 1 <br/>200 ohm resistor * 1 <br/>1N5819 diode * 1 <br/>3MM LED turns red * 1 <br/>150UH color ring inductance * 1 <br/>STC15F104W (burned program) * 1 <br/>TC4427 * 1 <br/>Foam balls * several <br/>8P IC socket * 1 <br/>MOC34063 * 1</p><p>Set 2: <br/>Ultrasonic levitator finished product X1<br/></p></div></div><p><br/></p>
