Why are we watching videos of tin sheeting now? When was the last wheel progress video?

I am not demanding a completed wheel like these other asswipes. It would be nice to see the progress he is making on the wheel, however.

Only three days or so left for the deadline. PM cycles are almost there.
It looks like Archer got the switch working by now.
I can't wait too

Go Archer Go!

just a thought here but....

has anyone tried placing a coil around the ferrite, in attempts to collect the collapsing field when the 'switch' contact is broken???

{EDIT} - my thinking behind this lies in my experimental evidence that the induced field in the ferrite is stronger than the field at the contact-point.

meaning it takes less energy to remove the contact-point, than it does to remove an object from the magnetized ferrite.


So, it stands to reason the colapsing field would provide more energy than it took to remove that small pin.
Mechanical Inductor/Generator anyone?

@ all builders, I believe there has been some confusion about "switching" ferrite. You CANNOT switch the poles WITHOUT greater power that created them when they were cast. But you can " switch on" a greater strength than they already have via Archers demonstration. i.e. put a magnet on steel to line up it's monkeys and it is magnitized, ferrite is soft iron , soft ( cheap) ferrite is like a mettallica cheap drunk   , wave your north pole and she will line up. Wave your south pole...nothing happens that is unless you have a big swinging north pole and she will change teams. 

@ Que, Greta vids, help me out here, I believe the metal rod extension held it in place, not the intensified field effect on round line suppresion (WTF) ferrite mags.(as good as your vids were, i would have liked to seen the effect without the ferrites), I just feel like your comments about iso ferrite created alot of confusion about everything. I love Canada. They got great whorebags.  damn you!!  and FYI check out Robgallagher on youtube, he'll get those big ass neo's apart.

if my comments mislead anyone it was for sure unintentional .. .
It has been my opinion since iso ferrite became the savior to the sword several days back that the ferrite was NOT indeed the answer to this problem .. and i said it too.
It is still to date my contention that iso ferrite will not make the wheel round ..

as for the pole switching ..
the iso ferrite that came from the emi suppresion clamp filters ( you saw those pieces on the wheel in my first video ) . .do in fact pole flip ( imo ) .
Or at least thats what i thought to be happening in my experiment to see if the ferrite could play a role as repulsive ..
Normally ferrite is attract mode only to a NEO ..both poles .. no matter what kind of ferrite it is ..
heres what i did that convinced me this pole flip thing was in fact accurate.

i took two equal strength neos ( smaller ones ) and set them so their poles repelled each other in my hands.
Lets say the magnet's poles were south and south - facing each other.( repulsion)

With the 2 magnets in repulsion ..
To the south side of one of them i stuck a piece of my iso ferrite were it happily clacked itself to the magnet  stuck to the south pole.
So the ferrite now stuck to the magnets south side also has it's south paw on the same side as the magnet ..

So with the ferrite now attached to the NEO's south we have something like this magnetically
N-NEO-S   S-(Ferrite)-N...S-NEO-N

The ferrite has adjusted it poles in consequence of the now attached neo's much stronger poles

So now try this ..
With the Ferritebacked NEO in one hand very slowly start to approach the other NEO..

At first.. further away you will start to feel a small amount of repulsion as the two south poles repel each other.
as you slowly approach the two NEO's  together .. the repel strength will build a bit ..

The ferrite is repelling the south faced NEO .. but when you cross a certain threshold near closer proximity
suddenly all the repulsion disappears - and the ferrite now clacks/jumps itself up against the other neo in full attraction mode.

i believe the only way the ferrite could exhibit this behavior is to have flipped it poles under the stress of the two neo's and changed them so that is attracted to the two neos one on each of it's sides ..

SO now you have two NEO's with a piece of ferrite in the middle which is attracted to each NEO on it's side.
If you did everything like i wrote it and you now remove the ferrite from between
the two NEO's - they should still be in their full repulsion mode. 
What just happened ? ?
i thought the ferrite flipped it poles ..
Thats why i made the statement ..
When i discovered this it was because i was looking for a way for ISO ferrite to play a role as repulsive ..

Cheers

P.s more coming a bit later ..

Well then......

The playing amounted to herbal remedy as I have no ferrite mags (Oh woe is me!), but after medicinal care I decided to finger paint to explain my latest tangent.

The attached pic is a top view.
Please assume the bottom is a mirror image (this means 2 "C" shaped ring neos top/bottom).

The rest should be self explanatory with the captions in pic.

@ capt

Nice to see you've done a 180 and are posting REALLY GOOD content now.
Man, it was a long time coming, but you're making up for it!

I love the "wonderbar" (flat crowbar)!

@X000

Nice use of allegory in your explanation  dude!
Although I'll pass up the Metallica chick for Allison Krause or Ricki Lee Jones (maybe Sheryl Crow).   

@ smoky

Still lurking in the shadows, but if it aids and abets such good insight, it's all good.

@ all

Slice and dice this concept (smoky's additional content may mean a few design changes in it, but I can live with that) kids!



P.S. Turning either the outer MkE array track or the inner neo hub mag could effectively be the on/off switch.

EDIT

With the consideration of the neo hub and the soft iron rods, a leaf spring follower might not be necessary depending on spacing between the rod and the hub.
