DIY Ultrasonic Levitation Kit – 12V Acoustic Suspension Project

Build Your Own Acoustic Levitation Device – A Fascinating DIY Electronics Project

Experience the magic of physics with this DIY Ultrasonic Levitation Kit! Using standing sound waves generated by ultrasonic transducers, this kit lets you suspend small lightweight objects — like foam balls or small seeds — completely in mid-air. A perfect hands-on soldering project for electronics enthusiasts, students, hobbyists, and science lovers of all ages.

Made in Mainland China.

Key Features

• Acoustic Suspension Technology: Generates standing ultrasonic waves that create pressure nodes capable of levitating small particles in space — no magnets, no tricks.
• DIY Soldering Project: Comes as an unassembled SMD kit, giving you a rewarding hands-on build experience from start to finish.
• Dual LED Indicators: Red LED signals power on; Green LED confirms active ultrasonic suspension — so you always know the system is working.
• Stable Long-Duration Levitation: Tested to maintain stable suspension for 24+ hours continuously. The mainboard may become slightly warm during extended operation — this is normal.
• Compact Form Factor: Dimensions of 42mm (L) × 42mm (W) × 62mm (H) with a 22mm probe spacing — desktop-friendly and portable.
• 12V DC Power Input: Operates at DC 12V with a low current draw of under 70mA, making it energy-efficient and safe for bench use.

Frequently Asked Questions

Q: What power supply do I need to run the DIY Ultrasonic Levitation Kit?

A: The kit requires a DC 12V power supply with a current output capable of providing at least 70mA. A standard 12V DC wall adapter (not included) works perfectly for powering this ultrasonic suspension kit.

Q: Is soldering experience required to assemble this ultrasonic levitation kit?

A: Basic soldering skills are recommended, as this is an SMD-based DIY electronics kit. It is a great project for intermediate hobbyists looking to practice SMD soldering while building a visually impressive acoustic levitation device.

Q: How long can the levitation kit run continuously?

A: Testing has shown the kit can maintain stable acoustic suspension for 24 hours or more. During extended operation, the mainboard may become slightly warm — this is expected and within normal operating parameters.

Q: What objects can be levitated with this ultrasonic kit?

A: Small, lightweight objects work best — such as tiny polystyrene foam balls, small seeds, paper bits, or lightweight particles. Heavier or denser objects will not be suspended by the ultrasonic standing waves produced by this kit.
