Mechanical Resonance (Projects)

Hey brad

Just a curious thing.  When we have say 1 subwoofer and it plays at 100db at 100w, and if we add another sub at 100w we get 106db. Now, it takes a doubling of power to make the single sub get to 103db. So from what I know, we can run 2 subs at 50w each, same total power of the single sub example and we will have 103db. Do you see the advantage???



Would be interesting to see.    Lol, if you put 25w each to 4 subs, you get 106db.  12.5w to each of 8 subs, 109db.

So now, if it works with 2 coils in series and the pendulum moves more, then I suppose we can count on even more savings from the pendulum movement.

Hope I got that right. Have to go. didnt eat today yet.

So, if you happen to have another drive coil just like the one you had shown in the vid and put it on the other side of the mast, then put it in series with the other coil for a push pull config, at the same total power input (will have to make voltage adjustments to get the same total power), you should get more movement of the mast for less input.

We are on the same wave length here,as i just came in from the workshop to grab a coffee,and catch up on the post here. Thing is,i am half way doing exactly what you suggest above lol.
I have just been pulling another one of those transformers(that i have boxes of)apart to get the primary coil from.

The same thing applies with magnetic field's,where if you add two fields together that are the same in strength,you end up with nearly 3 times the field strength of one of the magnet-not just twice the strength.

I am using a strip of spring steel,so i would think that i am also loosing a bit of power to eddy currents as well--but not much,as the steel strip will have a high magnetic field induced into it already by the neo PM.

I also want to place an air core coil around the PM,so as i can see what happens to the field of that PM when the electromagnet fires--there may be some answers in there.

One odd thing i have found,is when you shift the frequency of the electromagnet above the resonant frequency of the oscillating strip,the amplitude coils output shifts out of phase one way,and if i reduce the frequency of the electromagnet below that of the oscillating strips resonant frequency,the amplitude coils output shifts out of phase in the opposite direction .

Much more to discover,and much more fun to be had.

Very cool Brad

My day is free tomorrow.  If you noticed the mags at the bottom of my strip near the base, I was applying the drill input there. Almost right above the base brackets and can get the vibration to happen pretty darn good. My later plan for that it to make a short duration, high power, pulse coil to 'tap' (may even hear it ) the lower magnets. Like Tesla did with the tapper box on the building.  Now what smoky was talking about that I just realized now is to up the freq and get the strip to say have a bend in the strip at 2 times the freq, possibly the top is near as still as the base, and up the freq again and have 2 bends in the vibration if the strip.  More neat stuff to do.

Like you said, I can see a lot of things to work with and do here.

When i was getting the battery to oscillate on the JT circuit, at times it was hard to lock in to the batts peak freq and as I slowly adjusted the resonance would grow then jump to another phase and lower level, and the same back in the other direction.  Havnt gotten to finding out why it happens in one config of parts values and not another. But possibly similar to whats happening for you. Obviously your mast shifts out of phase on each side, as I doubt that your pickup coil just so happens to be reacting at those freq.

to avoid any confusion with what I was talking about...
I have drawn an image.
pardon my crude artistic abilities.
the red arc represents the path of travel (standing wave)
of the rod.
the green line is the "other half" of the wave, the mechanics of which do not really apply to this set-up.

the result of this, the mathematics we use here, are half-wave mechanics.
the "wave-length" represented by the distance traveled, and the associated 'arc' of travel
establish a mechanical 'wave', which propagates at the velocity of the rod.
This is half of the total wavelength of the standing wave being created.

like sending a pulse down a rope tied to a post.
the pulse hits the fixed end, and the resulting wave travels back in phase
the result with the rope, is constructive interference, and an increase in amplitude.

Here, amplitude is fixed, and the result is an increase in 'torque', and to some degree, velocity.

the other thing to consider, is the length of the rod.
its kind of like a pendulum + a spring.
it will assume a certain vibration.
examine a single-pulse and let it oscillate.

in part because of the location of the drive-magnet/coil input
and in part because of a constant resultant between the 'springyness' of the base,
the type of metal (density), and its' length.

when the drive coil freq. approaches a frequency the rod likes to oscillate at,
it will take less power, and greater torque and "distance" will be achieved.

on the return stroke, once the rod is oscillating,
in resonance, it has the maximum swing length.
the rod can approach during the time the coil is charging.
this sort of "loads" the coil,
giving it a harder kick
very little changes happen to the magnet itself,
but the magnet is "deeper" into the field when the coil kicks.
if that makes any sense...
There is also some degree of 'reverse' induction, as the drive magnet approaches the coil.

anyways, here is my stupid picture..

The ever so mysterious flywheel engine, here is perhaps a more revealing video then the others out there, where somebody from a foreign country demonstrates what seems to be Free energy.

And what do you think of this concept? Would this create overunity?  I design this, I do not think it will work, but there may remain... A bigger secret, the pulse of Lawrence Tseung^, is it true?

There good old explanation, I have also the vague rememberance of reading some theory about a nasa shuttle, where they would, "break the shuttle", at the right moment, pardon my ignorance I dont remember nor did I fully understand the significance of that article.

If you wish to make a motor with mechanical resonance, I believe it is pointless and impossible, I am sure, it was tried too much.
