    Acoustic Tractor Beam

    Hi Asier,Two questions:I successfully made the tractor beam and everything seems to work fine, however I am getting a small ticking/popping sound from my transducers. Is this a sign of a short circuit or something similar?Second, what are the important parameters here for scaling up this project (larger hemisphere)? Is spacing between the transducers important relative to sound wavelength?

    Hello, would these transducers work? The data sheets are very similar.http://vi.raptor.ebaydesc.com/ws/eBayISAPI.dll?ViewItemDescV4&item=131590233040&category=36332&pm=1&ds=0&t=1487787421761
