That’s insane! 🤯
A student built an acoustic levitation divide with an Arduino board.
He built it using an @arduino Nano, a motor driver, and 60 ultrasonic transducers that can levitate low-density objects in place indefinitely.
The transducers send out 40 kHz waves that create standing waves. The interference pattern produces nulls that trap objects. High-pressure areas form below and above the object, locking it in the low-pressure area between them.
The transducers produce two sound waves moving in opposing directions at the same frequency and amplitude.
The effect is that the low-pressure areas don't appear to move, like whipping a rope from both ends and having the wave meet in the middle.
Sound waves are oscillating at high and low pressures. By creating a sound wave that doesn't move forward (a standing wave), you create areas of constant pressure. 🔉
Objects get trapped in the null points between high-pressure zones.
The craziest part is that this was made more than 7 years ago!

Transistors, with their ability to act as switches or amplifiers, have revolutionized the electronics industry and are now used in countless devices that have become an integral part of our daily lives, like computers, phones, and televisions.
Hey Freelancers #Upwork workers, are you available for working with me?
Got Upwork plus account and have newer post getting to easy. I can swap to you some jobs if you are interested.
