Shak chasing 85000 reads the flame wars bring the crowd [maybe not completely] Archer is inspired by this [IMO]it gets /keeps him thinking    I think it human nature to have an adversary to beat    WELL I always did best in this venue maybe thats weird   Archer has much bigger adversaries [not here] then I ever had   Chet

You're right, competition does get the best out of people.

@freddy and exx,
It looks like you guys made a horseshoe magnet with the attracting force equals the repelling force at the end. So the traveling magnet dutifully goes from the start end to the end end. It seems you need the acceleration of the attraction side and want to get rid of the stop/repulsion side. So instead of thinking 2 dimensionally think 3. As your track goes to the 1 o'clock it is countersunk deeper into the backboard. If the force is reduced 1/4 by distance, the deeper the track sinks away from the traveling magnet, the less the stopping force. So when the stop end approaches the start end the forces are not equal. The stop end is way below the force of the start end, and the cycle can restart. Exx think ramping down the gravity side of the clock face. The traveling magnet stays in the plane but the magnets under the track move away from the plane until the stopping force is very very small.

I don't have the magnets to play with for this track/traveller setup, but maybe you guys can try it.

'Xactly (Exactly) so dude.

I've raised the plexi w/ uncooked penne pasta and had less of a wall, but less acceleration as well. I've been a BIG proponent of the ramp (as people know ) and will try that shortly both in static and dynamic (the Bat-track see-saw action) configurations to see what's going on.

I also have yet to tack any weight onto the roller arm and see how much it can get up to 12. Shak has a very good point that we shouldn't forget about the outside weights!

The things I'm finding most exciting about the results I've shown is that there need be no controlling arm to keep the roller on track which means it should be able to exert force from that effect and shaped MkE array arcs can assist lateral rod shift.

In fact, with the MkE, I don't see why the weights couldn't be magnetized on their outside edge and have the mags of the original RW arranged so they are repel ONLY to assist the track shift and negate momentum loss due to it.
The attraction arrays of the RW can be done away with, as trying to "shove" a roller sideways OFF the MkE track takes some real force, EDIT (I meant opposing field below.....durrrrrrrrrrrrrrrrrr) and creates as much "up" force as laterally forward force needed to force one past the other when the fields encounter each other "sideways" if you have the MkE in polarity sync (N/N-S/S) encounter.
This is why I tried the roller mag without the arm 1st to see how much centrifugal force it could withstand.
Seems that each sides attract of the MkE can handle some pretty good weight.
I still don't know............yet. 

The attract side of the was to assist the repel lift and then maintain the vertical position in the RW, while the repel side tapered proportionately in the same manner.

Attract starts strong and gradually weakens.
Repel starts with just enough to assist the attract side (figuring in the effect and duration of rotation) in lifting the weighted rod and increasing to a maintained point as once the rod mag is "skipping" on the tops of the repel fields at full strength, the attract side can be very weak, and again, not hinder momentum.
The field "end to end" effect is much like the Q-tip theory of mine where when the ends are meeting, each field is providing its own ramp (like trying to set one basketball on top of another) and the opposing ramps double the leverage effect to rob the least amount of momentum.


The MkE is an attract array all it's own and will keep a mag centered in the track up to a certain weight depending on the mag strength, so no RW attract arrays are needed (I do reserve the right to completely change this position once more testing has been done and I have more data as to whether properly spaced attract or repel ancillary mags could help with momentum consistency and conservation).

The stubborn bit is the MkE exit wall seems just as tough as the RW repel wall, even with the gravity assist MkE is able to harness that RW repel can't.

If we find the way to kill (or ramp) that MkE exit wall..............

.......... the wheel is done.

All that remains is fine tuning it to the RPM closest that centrifugal force will allow it to run.

RW is slow, but has torque.
MkE speed can (to my knowledge at this time) only be limited to the strength of the mags used, but has much less torque.

The idea that popped into my head while writing this is to make a stacked and touching pyramid of MkE arrays at the end of the track that are solidly touching to, in effect, create a magnetic field pointing down like this:

                                  N                  XXXXXXXXXXX           S
                                  N                     XXXXXXXXX             S
                                  N                       XXXXXXX                S
                                  N                        XXXXX                    S
                                  N                           XXX                      S
                                  N                             X                         S

That's how the world warps for me these days.

I'll give it a try here shortly, but the experiment requests and previous ideas are going to take a bit of time to get through, so if you're @ loose ends.........

Give it a whirl, Earl!

@All,

Just remembered in 'video 3 of shunt demonstration' Archer broke the wall using a small hill to get a gravity assist. You would have to lay the wheel down, add a hinge arm and use inward slanted hills with a roller. Tough, but it can be done. Let the games begin


@Queue,

I think Archer has said something about the arm for the new loop would need to be one sided. If you just need a little more to get there that may do it. He also said before that the arms should be light as possible with the majority of the weight concentrated at the ends.

Good Luck, Larry

Archer Quinn's Mayernik Array . ..

i hope Archer finishes his wheel soon. i have spent MANY hours playing with this array and to date have no luck closing the loop. I made a last video replicating AQ's lift from 10 to 12 over the wall and break out after gaining some momentum from gravity. Many have noted that with more magnets Archer could have lifted from 6 instead of 10 to be able to then close the loop.
Well i have more magnets .. i have many magnets :-)

The wheel and magnetic array in this test does both lifts .. from 6 to 12 over the top ..
AND
10 to 12 over the top and break the wall with seemingly lots of extra energy ..

The damn frustrating thing about this array and working/playing with it is that it always seems to be JUST ABOUT to work .. a little more energy needed, more mags , more powerful mags .. whatever .. always the same story .. little bit short to be able retstart the cycle and self perpetuate. I would happily buff and shine each and every magnet i have or own .. if i thought it would provide that extra . .gleam in the array's eye..

Trying to get a restart cycle .. using this array is just not happening .. IMO that is .
Prove me wrong .. someone .. anyone .. 
Archer Quinn.

i started prototyping arrays to appease my own curiosity and to know if what Archer was building might work.
i am still waiting for his wheel and i did purchase his plans so i guess eventually that chapter will tell.

As magnetic arrays go .. this one was fun to play with.
My fingers hurt :-)

Hi queue
Thanks for showing and explaining clearly what I have been trying to say since Archer first showed my onewaygate, I know you did your experiments because you thought it could be a good idea that may work but in doing so you validated what I have been saying and I thank you for that.

Another idea....
What if the plate/wheel was angled away from the array so that it is physically further away (more gap) near the exit point?

This might just change the location of the wall, but I was thinking that as the roller/arm gets closer to the sticky spot the magnetic attraction is reduced.

I will try to illustrate this when I get a chance for those that don't follow what I mean.

Sorry for just throwing ideas out there willy-nilly. I promise I'll be able to perform some experiments of my own soon. I currently have a few magnets on the way from the good old U.S. of A. It worked out cheaper for some bizarre reason, unless someone can point me to a good, cheap local distributor (I'm in Australia, near Sydney).

Hi Shakman
There is a place in mascot sydney that sells any type of magnet you want and will make specially designed magnets if you want to, I can remember the name at the moment but you can google magnets for sale in Australia to find it.
