Acoustic Levitation?

I want to know if anyone knows a way to do this at home. Acoustic levitation is a way to levitate objects in space using sound waves. That site gave a very thorough explanation of how it works, but not how to do it. If someone knows how, I'd love to see an instructable.

Quantum Levitation

Wow, just in time for The Mad Science Fair- an awesome magnetic levitation set-up. The Superconductivity Group at Tel Aviv University have been working on thin-films of superconductive materials and have found some...cool effects.  The thin films will apparently have a few defects, resulting in very specific areas where the magnetic field permeates.  This rigidly constrains the composite, allowing even "up-side down" levitation! (locked in space, beneath a magnet.)  Would be so awesome to play around with but apparently the deposition of the superconductive film is a real challenge, not to mention the sapphire substrate. A forum post at HI Capacity had these links, probably after a member saw Gizmodo's article "What the Hell Magnets? Why Are You So Amazing?"

Electromagnetic and Magnetic Levitation

Hi! I am setting up a levitation system and need to estimate the amount of voltage and current that is needed for a 2" dia. coil to produce 4800 Gauss. I don't have any restrictions/requirements on the core, number of turns, etc as long as it would produce 4800 Gauss with a 2" diameter. How can this be calculated? (I have spent a lot of time googling for such information, but I am pretty confused and didn't find how to calculate this) Thanks!

Creating an electromagnet as powerful as an NeFeB magnet with same size

Is this possible?So I'm working on this project on levitation using superconductor and strong NeFeB magnets. I'm try to determine the possibility of replacing the magnets with electromagnets equally as powerful and of the same size if not smaller. But I'm bit skeptic about the idea as I'm not sure how possible it will be to construct such electromagnet (or buy them preferable). Is this something that is possible? can anyone reading this give me recommendations? thanks

Grounding a magnetic levitation circuit

I need help understanding the circuit attached, from what i understand is that i can power it from a 12V mains adapter. The one i have is 1 amp which i think is enough. But more importantly for the grounds, that i should connect them all up to the ground coming from the 6 pin on the left opamp. As though this ground would act as a central one, with all the other ones connected to it. Is this correct or not, if not then please explain to me how i should ground this circuit. I claim no rights to the content in the link and am using it for my own recreational purposes. http://uzzors2k.4hv.org/projectfiles/magneticlevitator/Magnetic%20Levitator%20circuit.GIF

Does Instructables have a policy or consensus on plagiarism?

I was going through all (yes, all) of the I'bles tagged in the Science category (to help populate the Physics Group) and ran across the following:Build Levitation Device. published by ermak777 on 12 Feb 2008.Build Levitation Device. published by kinofanat on 14 May 2008.The duplication is quite astonishing, right down to the typos in the description of the video. I've flagged the later edition as "Inappropriate", to help staff find it.

How to levitate a playing card with your cellphone!

I got about halfway through making one of these before I started questioning its seriousness. Is it a joke? Or, hopefully, is it valid? UPDATE:Don't you just love who gullible some people are? ; ) Anyway, now that I've shared this with everyone, should I delete this topic. I'm not sure how it could benefit anyone else by leaving it up, and I try to clean up my messes.If anyone knows the latter to be true, could you give the scientific explanation for why a cellphone can levitate a playing card?Looking up how to add a video now. :P Here's the URL in the meantime:http://www.metacafe.com/watch/448034/secret_science_anti_gravity_revealed_homemade Errr...Perhaps I'll make an Instructable on how to not read the entire set of directions in an Instructable on how to make videos. Mmmmm...recursion :P

Real-life Back to the Future 2 hoverboard

French artist Nils Guadagnin has built his very own hoverboard based on the hoverboards in Back to the Future II. It's pink, it's a board, and it actually does hover when placed on its platform. Integrated into the board and the plinth is an electromagnetic system which levitates the board. A laser system stabilises the object in the air. The board is hovering with the help of two CLM-1+ levitation modules made by Crealev. Hoverboard Project via geekologie

Embedded video bug

I updated a video in my I'ble for the EL wire contest judging period. Now the video is gone and alas, I am not a finalist! Sadness :-( Whether or not the video had to do with the judging, it looks like embedded videos are not displaying from Vimeo. I tried a couple times with a couple videos and none will display in my published I'ble. (https://www.instructables.com/id/EL-Levitation-Wand/). Thought you'd like to know.

Electromegnetic Levatation Glove?

I've seen some devices which use electromagnets controlled by microchips (like this https://www.instructables.com/id/Electromagnetic-Floater/) to levitate small objects. I'm wondering if that same technology could be put into a sort of glove, allowing the user to levitate small metallic or magnetic objects, and maybe even pull or shoot* them? It would have a small electromagnet in each fingertip, as well as a larger one on the palm. All electromagnets could pull upwards on the object if the palm is facing down, and the object was below them. Only the fingertips would pull if it's facing up, and the object is above the palm, (but slightly below the level of the fingertips) The problem would be sensing where the object is, and adjusting the power of each magnet based on that position, and the the position of the electromagnets. *using actual magnetic repulsion would be tricky, but you could, say, have the object sit in the palm of the hand, with fingers outstretched,  then have it attracted to the electromagnets in the fingers, which turn off just as it passes by them. It retains its momentum and shoots out. So, if anyone want to confirm if this is feasible or not (or even want to make it), please post!

Anti Gravity Idea...

OK I had this idea. I was online and thought up this idea for an anti gravity machine. This is it: use extremely static negatively charged materials for anti gravity. It could work the same way lightning clouds do. The base of the cloud is negatively charged and the ground become positively charged. Now if the material of the anti gravity "thing" is charged with static electricity, wouldn't it repel the ground? Now I am by far no expert in any of this...I just thought it up. What do you guys think?

VAWT a new way to wind generation

Guys need help to realise its feasiblity and pros & cons. This project will comprise of a renewable energy source which is controlled by TI msp430 controller by closed loop system. This renewable energy source will use a magnetically levitated vertical axis wind turbine with single phase permanent magnet alternator made by our team. There will be 3 stationary wind guide vanes/flaps of concave shape on the outer periphery of turbine. These vanes will be controlled by dc gear motor for constant wind flow and protection against high speed winds. Using perturb & observe MPPT algorithm on DC-DC boost converter, constant DC voltage for GRID integration is made. A lower energy Bluetooth module will send data on user computer about whole system parameter, hence making the whole system to be smart and hence data is saved in database. https://www.youtube.com/watch?v=fC5hYLjhO9U

Can a magnetic propulsion system be achieved

Earnshaw's theorem states that a collection of point charges cannot be maintained in a stable stationary equilibrium configuration solely by the electrostatic interaction of the charges. This was first proven by British mathematician Samuel Earnshaw in 1842. It is usually referenced to magnetic fields, but originally applied to electrostatic fields. It applies to the classical inverse-square law forces (electric and gravitational) and also to the magnetic forces of permanent magnets and paramagnetic materials or any combination, (but not diamagnetic materials). Earnshaw's theorem has no exceptions for unmoving permanent ferro-magnets. However, moving ferromagnets, certain electromagnetic systems, pseudo-levitation and diamagnetic materials are areas to which Earnshaw's theorem doesn't apply and thus can seem to be exceptions, though in fact these exploit the constraints of the theorem.  Can we develop a safer cleaner transportation method that involves electro magnets that can propel cars using the city's grid to adjust the power on the street or road to move cars. similar to  famous movies vehicles like STAR WARS(c) Repulsor Lift(c) technology or The MATRIX(c) Ships OSIRIS?

Miniature chainsaw, mortar and ping pong blower

(a few tiny ideas) Basically a toy chainsaw that can cut through paper. Using hobby-R/C-like parts such as those tiny light motors would be a start. Reduced size, like a cellphone at most, mountable on a figurine soldier would be great. The miniature mortar should throw marbles on "mortar trajectories", you should be able to set the angle of the launch and (optionally) somehow the speed, though this wouldn't be necessary if the angle part is done well and the power is relatively constant at all shots. For ease it should be built only for angles above 45 degrees and the angle slider (or whatever the solution) should have marks (ticks) such that a user can remember and even create tables if he so wishes, in his war against coffee cups. Simplest solutions of "powering" would be rubber bands or coils from broken toys. A ping pong blower would be a tiny but strong fan (brushless outrunner motor) that keeps a ping pong ball "levitating" in mid-air straight up, but most excitingly even blown under an angle too. This wouldn't be a problem (physics takes care of it alone) just that the mount of the fan (ducted or not) should be operated and tilted as needed. This "levitron" would be a nice display on the desk running as long there's juice in the battery or else. Sorry if I'm not posting in the right place, these are just some ideas i'd love to build but i'm too clumsy and lazy :( Though my source of inspiration is the variety of USB gadgets commercially available, i'd like these to be more "free" and simpler if possible.

Magnetically Propelled Bicycle

I was told that I should make a forum topic out of this. So here it is:Here is a link to my upublished instructable:Magnetically Propelled BicycleI came up with this two weeks ago while I was day dreaming about levitation and magnets.The idea is that one stationary magnet set up on the middle of a bicycle negative facing front, can push two magnets bolted together, each facing negative, with an axle running through them and wheels on opposite sides. So when the stationary magnet'ss power is increased, the two magnets in front will be pushed, thus rotating the axle where the wheels are attached, adn obviously the wheels are turned.I say "when the power is increased" because hopefully an electro magnet can be used. I am not sure, but I think an electromagnet can be hooked up to a car battery, and then with some control device, more electricity can be sent to the magnet, possibly increasing the power ( I don't know much about this stuff so help me out here.Look at the schematics for all of the anatomy.I have not figured the turning system out completely, in the intro picture you may see that the turning wheel is connected to the rear by a bar ( In the way I believe it may work there will be two bars side by side, I can't really explain it yet). That is how I plan the turning to the controlled.If you have any ideas for this project, add a comment. I have not made this yet and am still creating it.Please, do not steal my idea, I am only 14 and just started inventing. I have no idea how the patenting system works and I do not have the money for it.I would also like to know more about electromagnets, how they work and where to buy them. I saw one site where the best electromagnet can "pull" like 1300 pounds, so this thing should go pretty fast if it is built properly. I reallly want to know if it is possible for electromagnets to push, that is the whole Idea for this. But if they can't, I've already drawn a simple schematic for pulling the wheels which is on the next page.I also want to add that the stationary magnet cannot be level with the rotating magnets, it will have to be a little above, and if you add a mechanism where the stationary magnet can move up and down, you can control the bike forwards and backwards.Hopefully, no one has a patent on this ( I've searched and haven't found one). And hopefully this will replace fossil fuel vehicles, although I doubt the government will allow that. THE WHEELS/ROTATING MAGNET IS NOT ATTACHED TO THE BICYCLE. IT IS ONLY CONNECTED BY AN AXLE RUNNING THROUGH IT. JUST LIKE A BICYCLE OR A CAR. Here is a link to what I was sorta thinking:Here Just turn it horizontally and add wheels to the ends. The gyro- thingy is like the rotating magnet and the base is like the stationary magnet.

looking around for tutorials

I am suggesting tutorials on the following. All passive components and prefereably vacuum tubes can be used to build the following circuits.   Analog computers that are programmable and hopefully intellegent. with these you should process many signals at the same time. and instead of displaying results on an oscillscope, make a monitor and a gui.   I have a theory for a power supply. I think it works im not technically able to build the entire circuit yet. It's all passive. its a passive AM radio that sends a 60 hz sine wave. then on the other end you have many many antennas attatched to a passive receiver circuit. because each antenna will induce an electric field from the air, you should be able to get lots more power out of the circuit than you put in. and because its antennas, its compact and light weight.   And if you can figure it out, you can build plasma rockets too. I need some more information on how plasmas travel through an electric field.   but you know if you want to, you can build cars, boats planes, houses, cookware, sensors, surveilance, recording studios, 3d printers etcetera in passive electronics and post tutorials on it.   I am getting somewhat close to growing carbon based electronic components on a tree. I have some(a few) molecules in mind and I am starting to research and make progress on sequencing DNA.   If you want this information it is simply yours. but I need analog flight simulators, spaceflight simulators, weather simulators that use chemistry and math to predict the weather, ocean simulators that simulate all of the bathymetry of the ocean to predict surf and erosion.   aircraft designers. I have a motor that i am designing like the following. It only uses permanent magnets at the moment and it works similar to an alternator. If you can figure it out, you can build it too.   I have an alternate way to make bearings by using cylindrical magnets(the kind with the hole in the middle) and one is attracting and one is repelling. this should be able to make it so that the magnets levitate and spin freely.   Again if you want this information it is yours. YOu can also make analog computers compatable with software that exists today like linux. it is possible. it just takes some time and some thought.   ANyhow anything you want make it wireless make it programmable and make it and post tutorials on it.   I want EVERYTHING to be wireless from the computers to the recording studios to the rockets.   ANyhow thanks and have fun and stuff and it might be fun and it would help everyone and would help your compnay to produce these tutorial but you know wireless guitars, wireless amps, wireless record players wireless cnc machines, wireless laser cutters wireless induction cooktops etcetera. you can even make a record player that instead of using that metal thing to vibrate, you can use like sonar. You know this is just some cool stuff to consider developing. The radio based power supply will work, it just needs some fine tuning and same with the motor, but yeah have fun and be easy with this stuff itll take a while. but you know if you build rockets, spin the rockets to create a strong electric field, but you know i could use tutorials on how plasmas move and accellerate through an electric field etcetera. and for god sake, build EVERYTHING!
