FAQ's

Q: How does the bead levitate?
A: The transducers create standing waves and produce 2 high pressure zones. The bead is sandwiched and held in-between these two zones.

Q: How does the bead move?
A: By changing the frequency of the sound waves emitted, the standing waves appear in different locations.

Q: Can the bead move sideways?
A: No, the tractor beam only allows the bead to move up and down.

Q: Do they all have to be Transmitters or Receivers or can you have a combination of them?
A: From testing, we found that they all have to be Transducers. You could also use transducers that are combination Transmitters/Receivers.

Q: How much power is needed to run the device?
A: You will need a total of 25 volts per levitation device to run each device, but you should be able to test all the components at 10V.

Q: What do I do if I don't have access to a 25 volt power supply?
A: You can easily buy a small DC-DC voltage booster that will allow you to take a small 5 volt battery and boost the voltage to 25V.
