When you make a generator of a tractor beam that can lift objects with DIY

For SF works like "Star Wars", as a technique to attract spaceships and luggageTractor beam"Will appear. In reality, we succeeded in making a tractor beam that floats objects by floating ultrasonic waves in 2015, but after more than one year passed, it has become possible to create generators considerably easily It seems.

The "tractor beam" itself focuses the laser light strongly and generates a very small amount of nanometer to micrometer unitDielectricMoveOptical tweezersIt is realized as. After that, as a technique for collecting fine samples even in vacuum in space explorationNASA advances researchIt was.

After that, in 2015Asier MarzoMr. et al.'s research team realized a tractor beam that allows objects to float and move in the air using ultrasonic waves.

About 2 years from there, "How to make a portable tractor beam" that you can do if you try hard is published on YouTube.

"Let's make your own acoustic tractor beam" ...


The electric circuit diagram looks something like this.


First, I will make a bowl with a 3D printer.



Soldering Arduino.


And the program.


Charge the battery.


Cut out hands next.


Drill a hole in the bowl ......


Drill a hole to hold it and attach it to your hand.


Hold boards and set them in your hands, and smoothly connect cables and so on.



Install the power switch.


It gradually becomes like it.


TransducerCheck


Attach the transducer inside the bowl.


Solder the cable to the surroundings.


Switch on after various work.


Succeeded to float things.




Links to materials are not prepared at the moment, but anyone will be able to get a portable sound tractor beam, if released.
