MylowHJ Replication - Discussion

[AquariuZ]

never mind.

Sure TinselKoala, sure.

So you failed to notice any changes at all between these last two videos hmmm.

There are two different Mylows:

One is enthousiastically showing the world his Howard Johnson replication
The other one is reluctantly showing the world crap while he knows he is going to have to self destruct.

One Mylow is Pre-Sterling
The other Mylow is Post-Sterling

Please check when Sterling and PES first became involved in this project and cross check the dates of the videos.

Interesting huh? ...or is that also too much to ask?

Further discussion is futile, I know what I know and I know what I see.

And I also know what I am going to do.

Can you guess?

I don't suppose it is even remotely possible that there is some one else nearby. No, that would be too easy.

No, I'm not going to do the acceleration analysis. You do it. I'm tired. And it is you, after all, who is trying to make a point. I've already made mine, so if you think this video is proof of anything I suggest you , yes, try to replicate it.

Who? The invisible man?

Again: if the wheel is in full frame, unless there is an invisible hand of god sustaining the momentum, the wheel should decelerate if the setup does not work. If the disc is intermittently accelerating and decelerating (gaps!!) then the setup is authentic. No hand, no hidden motor.

Go on, admit it, you want to know too.

And ofcourse you are tired, you have been spending the last 24 hours proving to the world the setup can be faked and you did a great job in exposing the last project as a fake.

Your government is grateful, really.

Touko performed perspective correction  (he mentions the need to do so in his vid comments, maybe you didn´t notice)  and then tracked the dot, it´s angle in each frame then being derived with standard geometry. The plot he produced was a true representation of the angular velocity of the disk as a function of time.

Not sure how video compression could affect the plot in any way other than introducing very slight noise to the curve, please eleborate.

P.S.Enjoy your flight.

Thanks.

Thank goodness it is delayed. The hurry-up part of the problem was solved with a phone call.

As for the graph shown and perspective correction.... No. I don't recall reading that in the video. Since I've used all of the apps I saw mentioned I doubt I misunderstood what I did see. I do recall you mentioning it in one of your posts.

The graph is confusing at best. There are no numbers, no way to determine range of angular velocity. If the bottom of the chart was zero (so I assumed) then I couldn't believe the RPM would deviate that much over one rotation. At least not unless he didn't perform the correction.

To me the sine shows rotation of the elliptical. The reported speed will change at each quadrant because he is on an angle.

I do recall him mentioning balance and wobble. That should show up only as minor noise instead of the complete sine.

As far as I'm concerned the graph shows speed degradation after the rightful kick wears off just after passing the stator, slight slowdown just before the stator and a repeated kick just after it.

I would love to view it again. Anyone have a link?
or better yet, some numbers to go with the graph?

Just like everyone else my understanding of all things is based upon my experiences. I can easily understand folks screaming foul and finding ways to prove it foul.

After all, it is much easier to debunk than make it work. Especially if you have absolutely no experiences with things that defy explanation using common information.

Not that I have, of course

Hi Bep,

My thoughts on the overall sin wave are:

If you externally drive a disk that is not level and unbalanced you will observe in its velocity profile one sin wave per revolution. It will not manifest as noise it will be a sin wave.

Remember the graph plots speed as a function of time.

One half of the sin wave, the bottom half, is caused by the rotor going uphill. They don´t want to go uphill and so slow the disk down.

The other half of the sin wave, the faster top half, is caused by the rotor mags going downhill and so adding to the disc speed.

So with a rotating unbalanced and not flat disk you will see this sin function.

Numbers on the graph are not really needed, we can tell how much X axis is required to make one rev because we get one rotor&stator interaction spike for every one revolution. Plus the absolute speed on the y axis does not really need to be known.

To make things even more intuitive, imagine a disc that´s not just a little off the horizontal, imagine one at 45deg or even vertical 90deg, then I´m sure you can visualise how a weight on it will swing faster at the bottom of the circle and slower at the top, those two extremes of velocities make up the top and bottom of the sin wave. Kind of like a pendulum that goes all the way over.

However just by seeing  the sin wave does not PROVE external drive. But what gives it away is the fact that the half of the sin wave that is on the opposite side to the rotor&stator interaction.That half of the sin wave shows accelleration over it. Clearly indicative of acceleration not due to the stator mags.

lol mylow made me think alot, I´ve spent too long writing on this subject, gonna have to get back to my HV pulsed cadaceus experiment, and making a flyback driver that doesn´t fry ICs so often. Back to the shadows, where the real work is done!

Greetings All

I just received this link in my email and I figured best to pass it on.
