Thaelin,

you rule!


All, read up ....now build something that makes a mess of your rings.using bottles and coils


Then ...and only then after exhaustive mixing  tell me im full of it. Or there is not enough information

Excuse me because my English is not perfect and I can't understand "running with gain" sentence. Does it mean the usage of positive feedback to always adjust output power for wide range of attached loads automatically ?

@ BEP
   Thoes frequencies were relative just to the point. The actuals were
                Fundamental    35705
               3rd harmonic     107115
               5th harmonic     178525
               7th harmonic     249935

This is where they would run for the 15".

The pdf is 88k so I will try to tag it on here. If not, I will up the upload area
Its name is 0903_Harmonics.pdf

On an added note, funny how when you add the odd harmonics to a fundamental freq
how it goes from a sine to a square wave.

Yes - Fourier takes over here.

Your frequencies tried aren't new. What may be new to some is applying two frequencies say 35705 + 245000 can yield 4935.
How? A magnetostrictive core it will resonate at audio freeks that are subharmonics of the driving freeks' result.

(35705 * 7) - 245000 = 4935

So you have two drive freeks - 35705 and 245000

The difference is 4935 ( as seen by the core in acoustic/magnetostrictive mode )

The circumference of that part is acoustically resonant at 4935 but has its own magnetic field bacause it is carrying current.

That field - being in the middle of these outer coils - acts like a moving iron core - (ETR)

etc.

Speculation only folks - try it - it works but I'm not running with gain - yet.


Wah-Wah-Wah

@Wattsup,
A few pages back I posted a link to a book called Practical transformer hand book.
When I first saw this title I thought "pah what can this book teach me about transformers? I know everything about them". Now I realize I was very stupid.

I suggest you look at it. This and the comments in my previous post are from the same book.
