Howard Johnson Replication Tube Claim

[hansvonlieven]

You are talking about fascinating technical history here TK.

The lathe is almost as old as civilised humanity itself. The first lathes were adaptations of the potter's wheel which was foot operated and operated vertically. Soon they discovered that turning things was easier on a horizontal plane and they took the whole thing from there. Horizontal lathes were operated with a bow, as they are still used in some primitive societies.

We are talking pre-Egyptian for the ealiest recorded uses.

Just for fun

Hans is right when he says the smot device has been tried already but I think the effect of the aluminum on the pole glued to the plate is different.
This is actually not at all like anything Howard Johnson built and the added delayed effect of the aluminum plate is an entirely new concept.

Think of that little aluminum disk in everyone's electric meter. It rotates because of a changing magnetic field when you use power. With a spacing between the rotor magnets a similar condition may exist on Mylows disk where the field always pulls to a field already setup by the rotor magnets in the disk.

I understand all the reasons why Mylows motor probably does not work but if he says it does then I look for why it does because that is what we don't know.

Hmmm...

I finally had a chance to look at how the video analysis was 'probably' done. Of course you can't really tell because it really is just a video.
Certainly all possible on a Linux or BSD box with those applications.
Amazing how it is all so reliable when the original video source is only 'fairly' well timed then compressed in who knows what fashion.
I think I'll wait until I see a repeat on an duplicate motor without using a video recording before I rely upon that 'data'.
Oh! Sorry. There are no duplicates, are there?

Forgive me please if I appear to be a skeptic and I'm not jumping on the bandwagon.

All I wish to know is where are you folks hitting next? It would be nice to know what topic to avoid next. Certainly what videos and data to avoid posting would be good to know as well.

Nevermind, I forgot. I stopped sharing that type of info a long time ago.

Well, it may not be the same kind of motor, but I have posted a "NEW" Tacho Calibration video on YT for those who would like to test the validity of their remote analysis methods, whether it be in software or photodiodes taped to the screen... I logged the data on a calibrated non-contact tachometer with NIST traceable calibration, whatever that means...so one can use that video and compare the results from one's method with this graph right here:

(This graph is coarse; the data file has a sample every half a second. I can repeat at slower speeds too. )

(sorry I forgot to mention that this is a different one from those posted yesterday and is much easier to work with)

Hans and TK:

My Dad was a masterful machinist and he taught me every thing I know.  I asked him a similar question:  How do you make a machine that will make another machine to tolerances of +-.0001" with a machine that was built to +-.005".  He explained it to me and its too long and involved for here but, it has obviously been done so I guess that method worked, ha ha.  He said it was a good question though. (I was only like 12 at the time and just learning to run the machinery.)

Couldn't we do a test:

1. See how an analysis outcome is from a direct video source.

And compare:

2. See how the analysis outcome is from that video source after uploaded on youtube.

Thoughts?
