I like this one, from the same maker as the Arduino one above, but not using Arduino I think:

The sphere magnet doesn't want to flip over!

Check this guys channel on Youtube.  He has like 10 videos on his devices showing his experiments and progession.

Yep, he's the one who did the sphere levitator. Good find!

That is cool and it looks like he is using four coils as far as I can see. Note the oscillations, I noted similar effects when levitating a 1" dia x 1/2" N42 Neo. I believe drag falls by the V^3 rule and a small flick would cause my levitated magnet to oscillate for hours. It kept oscillating so long I got bored and just turned the damn thing off.


That setup is a bit of a catch 22, if he is only using coils then at that distance the power draw would be large and if he uses a PM in the center then he would saturate his coils again increasing the power draw. It's a vicious circle although an Arduino and PID loop would easily solve the oscillation/hysteresis issues. It would also be fairly easy to apply a MPPT algorithm, not max power point tracking but minimum power point tracking if a central PM in repulsion were used.

TK and All:

OK, I have a weekend and some time.  I also have a salvaged roll of zip cord and, an 8" toroid from a huge transformer.

What would happen if I wound this toroid with the zip cord, bifilar so I don't have to separate the cord, and used a light bulb for a load, because if I shorted it my breaker would blow....and then, took a disk magnet and attempted to hover it above this toroid?

What would happen?  I realize that it would not be self-correcting as there are no hall sensors involved, but, would not the polarity of this toroid be reversing at 60 times/sec?  Is there a sweet spot distance/perfect weight that might hover with this cheap and dirty set up?  I have over 100 1/4 inch neos here that I could stick to a disk and vary the repulsion of the hovering disk if needed.

My question is...if there is 0 chance of this ever working, I will work on something else this weekend.  If there is a small chance that this "might" work, then I will give it a go.

I also have about 40 hard drive magnets I can use to keep the hovering disk from sliding off if needed also.

My other projects are on hold at the moment, and I am looking for something interesting to do.

What do you think?

Thanks,

Bill

PS  I realize that the hovering crystals video was due mainly to the visual effects of the crystals with simple leds showing through them, but, I think that the combination of hovering and the crystals, and the leds was simply brilliant.  Maybe I am easy to please but it was cool.

PPS  I was also just thinking that I could vary the amp draw by using different wattage light bulbs as well.  A 100 or a 150 bulb would draw a lot of amps through the toroid.  Of course, maybe this is a fool's errand.

This student has several levitators on this page.  (scroll down to see them)

He has one design that uses no hall sensors.  This kid really builds some nice stuff.  Here is a photo of one of them.

A very creative use of the levitators.... a back to the future desk top hover board!

Very nice indeed!

I've still got a long way to go, and I can tell that my finished project (if I ever do finish) is sure not going to look as nice as those do.    :'(

But my Hall sensor order arrived this afternoon and I put together a little testing and demonstration circuit:

TK:

Nice video!  Thank you for making it very clear how the hall sensors work.  I really like your circuit as it has many other uses besides repulsive magnetic levitation.

I began fooling around with the non-electronic old school style Levitron (spinning magnet top hovering over speaker magnets) and found out that there is a very narrow window of weight and height that this thing will work in.  No hovering here yet, but getting close.  Very interesting effects when over the hole in the center of the large magnets.

Well, I think I figured out that that guy with the beautiful hovering crystals device was simply using this commercially available
device from a hovering globe display

http://www.amazon.com/Fascinations-Levitron-Globe-World-Stage/dp/B002W8IH4Y/ref=sr_1_4?ie=UTF8&qid=1418577848&sr=8-4&keywords=floating+globes

It appears that he removed the magnetic disk from the globe (which it says you can do to hover your own items) and placed a piece of plexi over the base and then added the crystals.  It is still a nice effect, just not totally home made as I first thought.

I am really tempted to try to sell some stuff and purchase this device to play with.  Of course, I will take it apart, ha ha.  This is the lowest price I have found so far......I will think about it.

Bill

PS

Here is one without the globe (who cares?) for $52.00.  This is now the cheapest one thus far.

I wonder if he/it can levitate some of the sh!t he spreads here, or maybe some that he licks from the kings rim ?

Serious replies only.

This post speaks for itself.  I am only quoting it to preserve it so when it is edited, we can all see what was originally posted.  I suppose it would be nice if he at least used complete sentences but, oh well.

Those who can, do, Bill. Those who cannot do, just insult those who can. You know that. Let the pottymouth adolescent spew his garbage, it matters not one whit to people who actually build things that work, like you or me.

Boy, trolls sure get irritated when you troll them back.

Guess a dose of their own medicine isn't to their liking.

Cap happens to hold Patents in Canada and the US...with all artwork and specs done by his truly it shood be noted.

i rather doubt these 2 bozos have ever had an original thought.
