Magneticaly Levitated Turntable Platform. (1 Viewer)

Danny,

That may be the case but I am not giving up just yet..
Not all minds think alike and I may just stumble upon
something that works for me.. If not it will have been
a fun little experiment..

 

[Hank Frankenberg]

Brett, how about this: two rods attached to the base that go through holes in the top plate, right? Make the holes maybe 1/4" larger in diameter than the rods. Line the holes with a soft material, maybe foam tape, so that when the rods are touching the sides of the holes, they are touching the soft lining material, which would probably result in very litte vibration transfer. Experiment with different lining materials. Let us know what the results are.

Aren't the two pieces still coupled even if they are totally suspended with magnets? Wouldn't vibrations still be transfered to the top plate even if it were supported only with magnets? Think about it. If I floated one magnet over another, and then lowered the bottom magnet, the top magnet will lower the same amount as the bottom magnet.

Am I wrong in my thinking?

It would still "look" cool!

Ron,

That's actually a good point about the magnets still
transfering vibrations even if there is no physical
coupling of the 2 plates. Your thinking isn't wrong
at all. Low frequencies will cause vibrations in any
material anyway, even if it is completely decoupled
that's just fact I guess.

Hank,

You would have to line the holes with teflon or some
other ridgid material. If you use anything remotely
soft it won't stay lined up with magnets in a repulsive
configuration that's why the Dodd Audio and SAP unit
use hard steel rods to keep the top lined with the botom.

I am pondering a scheme using the magnets in an attraction
only setup and pulling the top plate in all directions.
It may work, it most likely won't..

There is no holy grail here I guess, unless you use some
Liquid Nitrogen and Superconductor Magnets

this is probably a bad idea, as it will make the vibration problem worse, but try this:

where the vertical lines are 'walls', the horizontal dashed lines is the floating plate, and the solid is the base

I'm aint no rocket scientist, but I would think that having a wall on either side would stop the top plate from sliding off, though it might be resting on the wall, trasnferring virbrations...

I don't see the whole point behind all this levitating though... why would you want to float your CD player? to reduce vibrations? the CD certinly wont skip. I've had my 5 disc carousel CD player in various places without it ever skipping once (it's sat on top of my TV for a while, not the sturdiest place).... I don't mean to put anyone's ideas down, but I just think this is overkill. I mean, how 'noticeable' can the difference be by levitating a cd player? You might as well hang it from the ceiling by string or wire.

Sorry, just the two cents of a tired and argumentative 16 year old...feel free to argue with my points, I'd love to know my faults...

Mark,

Actually the levitation deal is for a turntable not for my
cd player

It's just a brainstorm I had and something to play with if
I am bored (and I am....)

But my tube amps are enroute so I won't be bored come Thursday
Wahoo!

 

[Jeff Braddock]

Brett,
Did I ever email you the article on how to make your own heat pipe? I know you wanted me to, but I can't remember if I ever got around to it.

Ok, here comes the argumentative side of me again... what would vibrate that much to cause the turntable to skip?

you don't have any pnuematic devices in your media unit, do you?

 

[Danny Richie]

Mark,

The CD player or turn table need not skip to be effected by vibrations.

Vibrations in stands, shelves or whatever it is setting on can transmit noise that can be heard in the music.

For instance those that have tried the Levitator report a lower noise floor level. Space between notes are quieter. Soft subtle passings containing low level detail is clearer, etc.
