Hello everyone, I would like to start playing around with acoustic levitation. Apologies if this is the wrong sub-forum... I psoted in General, as I am not sure where the best place would be for this. My question: What equipment would be needed to start a simple acoustic levitation? I have no idea what "transducers" to acquire. And would I then need a waveform generator? Anything else? An amplifier? I attach an image for reference... that's basically what I'm trying to do. Nothing laboratory grade... more "home tinknering". All advice is greatly appreciated!
