1.Introduction:
  It is a DC 12V Ultrasonic Suspension Electronic Soldering DIY Kit. The suspending device operates at a frequency of 40KHZ in the air and can capture light objects with a density of 2-3MM, such as foam balls. It is a very interesting DIY electronic product which enables users to understand the circuit more clearly and learn soldering skills.

2.Feature:
  Experience Ultrasonic Suspension fascinating principle: Using two ultrasonic transmitters that emit a 40KHz frequency to each other, the kit can suspend lightweight objects with a diameter of 2-3mm, such as foam balls.

  Using method is easy: Simply clamp the small foam ball with tweezers and place it gently between the two ultrasonic probes to see it float in mid-air.

  Learning Working Principle: It refers to the Resonant Tank distance between the ultrasonic transmitter and the transmitter. During operation, the emitted and reflected waves continuously overlap to form a standing wave. The acoustic force received by the object at the standing wave node overcomes the effect of gravity and ultimately achieves the effect of suspension.

  Intermediate project - challenge to assemble: It requires a bit of skill. There are 3 different chips that you have to solder directly to the circuit board. This is definitely a project kind of thing. Everything other than soldering the 3 chips was pretty straightforward--most of those went through the circuit board and were easy to solder and snip off the excess. A really fun kit to challenge!

  Improve Electronic Soldering Skills: This DIY kit requires hand soldering of various components, providing an opportunity to improve soldering skills while also increasing interest in electronic technology. It's an ideal choice for electronics hobbyists, school and home education to try.
