Get ground from the Arduino to the common terminal of the buttons. Then, connect each of the buttons to D2 up , D3 down and D4 reset position.
In the final device we will use 25V but it is safer for the test equipment to work at 10V. If you use X10 probes then it is alright to use 25V throughout the process.
Get two probes and connect the grounds to a ground of the circuit, temporarily using the button pad ground is one of the easiest options.
Remember to put it back when finished. Signals from the same side are in phase while signals from opposite sides should be out of phase.
The easiest way to mark the polarity is to use the Arduino itself. This method does not require an oscilloscope or to poke the transducers inside.
Install the code from this section into the Arduino. Connect one wire to A0 and another wire to GND. When a transducer is connected between A0 and GND the signal will do one of the following things:.
It is important to not touch the transducers leg or the wires while doing that or the values will reset.
If it is still not possible to detect the polarity, poke the inside of the transducer with a thin wire and check if the spike goes up or down like in the obsolete method.
With a metal wire poke gently and repeatedly the inside of the transducer. Check the signal in the scope, if the first spike goes up, mark the ground leg.
If the spike goes down, mark the other leg. The transducers have polarity and they need to be marked. Do not trust manufacturer marks since they can be wrong.
This method is the one contained in the video, but we have an alternative one that is much easier one in the next step. First take ground and voltage from any of the Driver outputs.
Connect them to a transducer and also connect one probe to the same transducer. This probe will capture the emitted signal.
Take another probe and connect it to the transducer that needs to be marked, this will be the received signal. If the signals are in phase, mark the leg connected to ground.
If they are out of phase, mark the other leg. With the cable peeler, partially peel at the correct distance, later these exposed parts will be twisted around the transducers legs.
Once that you have made the cuts with the peeler, redistribute the plastic to keep a uniform length of cooper exposed.
Twist the cooper wires to make them more solid. Twist the exposed parts around the transducers legs, apply flux and solder.
Follow the pattern presented in the images. That is, all the grounds are connected together. The red wires of the same half go towards the same side.
This step is optional but it is convenient to check that all the transducers are connected correctly. Connect two extra marked transducers to the scope probes.
Be sure to connect the ground into the marked leg or at least connect the two transducers in the same way. With these transducers we can check the emitted signal of other transducers.
Transducers from the same half of the bowl should emit in phase. Transducers from opposite halves emit out of phase. Switch on the device, you should be able to feel a little bit the sound, or hear it if you point it into a big chunk of expanded polystyrene or foam.
Using an acoustically transparent sheet or tweezers you can place particles in the centre of the bowl above 1.
Depending on the size of the particle and how close it is to the bowl, you will be able to levitate it laterally or upside down.
It is also possible to levitate particles that are resting on a surface. We have presented how to build the most efficient device but there are others that require even less electronics although they are not as efficient in terms of levitation power to watts.
For the following devices you will need smaller transducers, wires and connectors, as well as a different version for the Arduino that generates always a 40kHZ signal.
Print the attached STL file. The transducers are fit in the bottom holes and they are all driven with the same signal. Question 9 days ago.
Hi, Please help me. I successfully made the tiny lev, and have tried to make the tractor beam but only one side of the array is working.
I replaced some of the wiring and tested it with a voltmeter and found the ground wires were fine, but the live wires weren't carrying a signal.
I am considering replacing the driver board but would appreciate any help. Question 8 months ago on Introduction. Hi there! I am trying to build this for my final year project in school and i do not have any experience when it comes to coding an arduino.
I have tried understanding the code but there are still many points where i do not understand. 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 8 months ago. To output data faster and in synchronized way you use PORTs which are a group of 8 pins.
Reply 8 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 8 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 11 months 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 12 months 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 11 months 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? Reply 1 year ago. Question 1 year ago.
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? Answer 1 year ago. 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.

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.
