Step 6: Start Floating

All that is left to do is start floating the objects.
This is done by holding the object under the magnets and slowly bringing it up. When It nears the point where it wants to float up, push the button. This will set the level to float at to the current height.

Next, hold it just below where you set the hold height, so the LED lights up. Hold it there until it simply floats out of your hand. This happens because the microcontroller slowly adjusts the hold height up, to where the electromagnets have enough power to control the object.

You may also notice some buzzing coming from the electromagnets. This can be easily fixed by inserting some padding around the electromagnets.

If you do make this I would love to see some photos. It would also be great to hear any comments you have.
<p>I have one of these devices -- a levitating globe. It's driving me bonkers because when the globe is suspended, I can hear a persistent noise. When it isn't (just glued to either the upper or lower magnets), the sound stops. What can I do to fix this? I find the noise very distracting, but nobody else can perceive it (I can hear significantly higher pitches than the average person which is why I think I'm picking it up).</p>
You should try adding a smoothing capacitor. The AC can generate a frequency through the electromagnets
Sorry what I ment to say is the transformer might make a frequency in the circuit
<p>I want to ask, what type of full H bridge IC that you use there?</p>
<p>I didn't Make it this way, but i made one. I have an instructable coming out soon on it.</p>

Do you have to set the location of the floating object with the button? Or can you test it find the point where it floats then turn off the current flowing to the magnets and let it drop. Then when turning the current back on, will the object return to the position that you initially tested??
<p>Also, where is the arduino file you mentioned??</p>
<p>Hey, I am looking at your project and hoping to build one. I just wondered about the wire coils, how many times were they wound around the magnetic core??? Please reply ASAP, I'm fast encroaching a deadline and need all the pointers I can get. Thankies!! </p>
would it be possible to make this into a hand held version by reversing the magnets to it is being pushed up rather than pulled up? this could be made into a glove similar to an iron man repusler. it will have to be a powerful electromagnet, but is would be Definitely worth it! the effects are ENDLESS! Magneto! Hadoken! Deathstar! dragonball!(have not been a fan of the last two, so no clue :P ) <br>what do you think?
You will need copper which repels
<p>Is the NO Button a push button or a switch?</p>
no button would be a normally open button
<p>Ttat is magic ! I don`t know why him can control the power. Who can help me ,I want to do such things.</p>
<p>Hey dude I'm having a hard time understanding the power inputs, I haven't worked from electrical schematics before and the H bridge I ordered is not like yours, any chance I could get your email and I could rack your brains? Cheers James</p>
Awesome ible...
wonder if you could beef it up and make floating furniture
And then sit in it. That would be awesome. Or a floating bed-sized ferofulid ball that you could sleep on.
it would suck if it stopped working when you were sleeping SMACK!
<p>&quot;Hey, what happened to the power...&quot; *BOOM* &quot;Whups, grandpa's up&quot;</p>
i think the ferofluid would be a bad idea the second you lay on it you would fall through and be soaked in it. not to mention you might drown.
Fill a waterbed with it?
that would probably work better but theres no telling what shape it would be or if it would float at all
It would spike you though
make it weak then
It would just be a regular water bed then
no, it'd be a really badass waterbed
It be a really badass floating water bed. PWNT fools.
It would be a watery blob,if it was in a skin of some kind it would be a cool bean bag chair
and if your pants were magnetic... now we're getting somewhere! haha
Owww, ultra wedgy
they actually do have floating beds but they are expensive<br>
send me a link i'd like 2 luk at it <br>
<p>I need to check this out at home</p>
DANG! <br>
holy crap thats cool<br>
<p>I wonder if you could coat a gemstone with molten iron on one end and float it.</p><p>Or if you could float liquid iron itself, since the process of making permanent magnets does involve melting the metal.</p>
<p>do all of the parts create the micro controller or do you need both</p>
<p>Where did you get your program from?</p>
Could you get the items part numbers? I am trying to make it and it is hard to find it without it.
This would look cool levitating ferro-fluid.
I totally agree. Although you'd need a permanent magnet for the ferrofluid to glom around, since it can only hover things that are already magnetic. Or invent a type of ferrofluid that naturally has its own field.
Use it as a thermometer or something; have the hover height depend on the temperature.
