Can u please advise me in the following questions? Thanks alot!!! So i am using an arduino nano, but i do not see a pin B2.
So which pin are u actually referring to? Also, i noticed that you are mostly only controlling one pin, but i thought we are supposed to control the output of 4?
What is the logic of the code doing, especially when the buttons are pressed. I thought all it is doing is changing the phases of certain transducers but the code looks extremely complicated.
I bought 10mm transducers instead. Am i still able to control the particle to levitate up and down? Im so sorry that im asking so many questions but i really tried understanding but am having serious problems.
Help will really be appreciated!! Thanks again!! Answer 9 months ago. To output data faster and in synchronized way you use PORTs which are a group of 8 pins.
Reply 9 months ago. And also, would i be able to manipulate particles if i use 10mm transducers but i scale down the 3d model of the dome?
Question 9 months ago. Hi, I just wanted to ask if is it possible to trap gas with this and move it around, or will it just leak out.
Trying to get this to work. Its will affect plate of water and move pieces of foam against table when upside down. I believe that the transmitters must be certain type as I can see no error.
Reply 1 year ago. Everything seems in order. Can you try with a small styrofoam sphere 1 or 2mm diameter , you can grab it from white packaging.
Could you take a picture of how the levitator deforms the water surface? Question 1 year ago. Hi I made it but instead of blinking sound l hear the sound continously.
Is some thing wrong? I tried to levitate small unolit pieces but it just moved and rotated. Answer 1 year ago. You can grab some from white packaging.
To check that they are emitting could you put a big chunk of styrofoam in front of it or a sheet of tin foil it should make some noise.
The link for the transmitters ended up getting me 10mm instead of 16mm, which I should have noticed before ordering.
Will 10mm transmitters work if I am able to mount them to a resized bowl? Hey, set everything up, but when I switch it on I can hear the transducers let out a steady pulse sounds like one per second.
Also, each component is flashing along with the pulse the display on the converter, L indicator on the nano, etc. Nothing is levitating, what's wrong with it?
I can't seem to find it, but the same effect happens if I disconnect the common ground from the transducers to the motor driver. Introduction: Acoustic Tractor Beam.
More by the author:. About: Build your own cutting-edge devices coming directly from UpnaLab. UpnaLab is the future interactive devices lab working with Ultrasonics, electromagnetism, lasers and more.
Components: 30x 16mm 40kHz Transducers The MSO-AH10T are the best but minimum order is , they are good so perhaps you can save them for future ultrasonic projects.
The transducers will be mounted in this bowl. This shape allows to naturally focus the beam. Attachments Bowl. It is very important to leave the OUT side of the Converter closer to the bowl.
Remove the indicated jumper of the Driver and keep it for later. Put the jumper between the D10 and D11 pins. Drill two through holes above the Driver.
Drill tree through holes below the Arduino. We will pass wires through these holes. The power switch provides current to the circuit either from a DC barrel or from the battery.
We will provide 7. Tining the tips of the wires will facilitate putting several wires in the same hole. These four wires will transfer the signals from the Arduino into the Driver.
Connect Arduino. A0,A1,A2,A3 to Driver. First Connect the battery be sure to use the right polarity. Switch on the device.
Rotate the potentiometer counterclockwise until you see 10V in the display. This step is optional but it is about time to check that everything is working fine.
Before the driver the signals should be 5Vpp and after the driver 10Vpp. If you have a multimeter and some copper tape, this method is quite simple to perform.
When a transducer is connected between A0 and GND the signal will do one of the following things: Signal goes down or remains at 0. Then, mark the leg connected to GND.
Signal goes up or remains at Then, Mark the leg connected to A0. Attachments nanoScope. This method for marking transducers is much easier than the previous one.
Just connect one probe to the transducer. Put the transducers face to face and check the signals in the scope.
Mark all the transducers. Put the transducers in the sockets with the marked legs pointing upwards towards the top. You do not need to populate the bottom row.
We need to wire the transducers to deliver power into them. Measure the needed length for the wire and give three extra hands for connecting it later.
Pay attention to the numbers, these numbers correspond to the driver numbers. Connect the ground from the bowl into the driver ground there will be another wire there.
Connect the 4 red wires from the bowl into the outputs of the Driver, respect the numbering. Transducers with the wrong polarity should be desoldered, rotated and resoldered.
Now that all the components are in place, it is time to reattach the bowl into the handler. Connect the ground from the bowl into the driver ground there is already another wire there.

Gravity impulse and gravity propulsion beams are traditionally areas of research from fringe physics that coincide with the concepts of tractor and repulsor beams.
A force field confined to a collimated beam with clean borders is one of the principal characteristics of tractor and repulsor beams.
For example, Robert L. Forward , Hughes Research Laboratories, Malibu, California, showed that general relativity theory allowed the generation of a very brief impulse of a gravity-like repulsive force along the axis of a helical torus containing accelerated condensed matter.
The mainstream scientific community has accepted Forward's work. But the works by Forward, Dröscher, and Häuser could not be considered as a form of repulsor or tractor beam because the predicted impulses and field effects were not confined to a well defined, collimated region.
The following are a summary of experiments and theories that resemble repulsor and tractor beam concepts:.
Kaplan, Senior Research Engineer, Electronics Division, Ryan Aeronautical Company, San Diego, had conducted experiments that justified planning for a more comprehensive research program.
In , Copenhagen physicists, L. Laurent, Nordisk Institut for Teoretisk Atomfysik, indicated general relativity theory and quantum theory allowed the generation and amplification of gravitons in a manner like the LASER.
In , Russian Professor of Chemistry, Yevgeny Podkletnov , and Nieminen, Tampere University of Technology , Tampere, Finland, discovered weight fluctuations in objects above an electromagnetically levitated, massive, composite superconducting disk.
Certain combinations of disk angular speeds and electromagnetic frequencies caused the fluctuations to stabilize at a 0.
The experiments with the toroidal disk yielded reductions that reached a maximum of 1. Reports about both sets of experiments stated the weight loss region was cylindrical, extending vertically for at least three meters above the disk.
Qualitative observations of an expulsive force at the border of the shielded zone were reported in the Fall of Italian physicist Giovanni Modanese, while a Von Humboldt Fellow at the Max Planck Institute for Physics , made the first attempt to provide a theoretical explanation of Podkletnov's observations.
Modanese described several effects in terms of responses to modifications to the local cosmological constant within the superconductor. Several groups around the world tried to replicate Podkletnov's gravity shielding observations.
Clive Woods, Department of Electrical and Computer Engineering, Iowa State University , those groups were not able to overcome the extremely challenging technical problems of replicating all aspects of the experimental conditions.
Unnikrishan, Tata Institute of Fundamental Research, Bombay, India , showed that if the effect had been caused by gravitational shielding, the shape of the shielded region would be similar to a shadow from the gravitational shield.
For example, the shape of the shielded region above a disk would be conical. The height of the cone's apex above the disk would vary directly with the height of the shielding disk above the earth.
That factor and others precipitated a recommendation to reclassify the effect as gravitational modification instead of gravitational shielding. The gravity impulse generator received further theoretical support from David Maker and Glen A.
A team of scientists at the Australian National University led by Professor Andrei Rode created a device similar to a tractor beam to move small particles 1.
This method confines particles to the centre of the beam using photophoresis , whereby illuminated sections of the particle have a higher temperature and thus impart more momentum to air molecules incident on the surface.
Owing to this method, it is impossible for such a device to work in space due to lack of air, but Professor Rode states that there are practical applications for the device on Earth such as, for example, the transportation of microscopic hazardous materials and other microscopic objects.
John Sinko and Clifford Schlecht researched a form of reversed-thrust laser propulsion as a macroscopic laser tractor beam.
In March , Chinese scientists posited that a specific type of Bessel beam a special kind of laser that does not diffract at the centre is capable of creating a pull-like effect on a given microscopic particle, forcing it towards the beam source.
They show explicitly that the necessary condition to realize a negative pulling optical force is the simultaneous excitation of multipoles in the particle and if the projection of the total photon momentum along the propagation direction is small, attractive optical force is possible.
Functioning tractor beams based on solenoidal modes of light were demonstrated in by physicists at New York University.
Orbital angular momentum transferred from the solenoid beam's helical wavefronts then drives the trapped objects upstream along the spiral.
Both Bessel-beam and solenoidal tractor beams are being considered for applications in space exploration by NASA. In , scientists at the Institute of Scientific Instruments ISI and the university of St Andrews succeeded in creating a tractor beam that pulls objects on a microscopic level.
Physicist from the Australian National University successfully built a reversible tractor beam, capable of transporting particles "one fifth of a millimetre in diameter a distance of up to 20 centimetres, around times further than previous experiments.
In , a team of researchers have built the world's first sonic tractor beam that can lift and move objects using sound waves. In , a research team from Tel-Aviv University led by Dr.
With this optical screw, particles were easily conveyed with controlled velocity and direction, upstream or downstream of the optical flow, over a distance of half a centimeter.
Science fiction movies and telecasts normally depict tractor and repulsor beams as audible, narrow rays of visible light that cover a small area of a target.
Tractor beams are most commonly used on spaceships and space stations. They are generally used in three ways:. In the latter case, there are usually countermeasures that can be employed against tractor beams.
These may include pressor beams a stronger pressor beam will counteract a weaker tractor beam or plane shears aka shearing planes a device to "cut" the tractor beam and render it ineffective.
In some fictional realities, shields can block tractor beams, or the generators can be disabled by sending a large amount of energy back up the beam to its source.
Tractor beams and pressor beams can be used together as a weapon: by attracting one side of an enemy spaceship while repelling the other, one can create severely damaging shear effects in its hull.
Another mode of destructive use of such beams is rapid alternating between pressing and pulling force in order to cause structural damage to the ship as well as inflicting lethal forces on its crew.
Two objects being brought together by a tractor beam are usually attracted toward their common centre of gravity.
This means that if a small spaceship applies a tractor beam to a large object such as a planet, the ship will be drawn towards the planet, rather than vice versa.
When the beams are manipulated correctly the target is drawn along with the interference pattern. The target may be moved toward or away from the emitter by changing the polarity of the beams.
Range of the beam affects the maximum mass that can be moved by the emitter, and the emitter subjects its anchoring structure to significant force.
