Hi Gwhy and all,

I just got my magnets and balls today.  I have been playing around with different tri-gate arrays and it seems that if you remove the back magnets you get less of a wall and even better if you extend the beginning and ending of the array.. I also found out that using this configuration that there is just a little wall if you go through the array, but if you go over the array, like you show in your videos, seems to be no wall at all... please try and let me know if you get the same results.

I have attached the configuration that I used, but I used 4 gate sets instead of three and when going over the array.. seems to be no wall.
Edit: playing with it more.. still maybe a little wall.. can't tell.. I'm using a piece of cardboard and can't see the array.. I wish I had a piece of the clear plastic.. I'll be ordering some of that next.

I can't do video so I'm hoping that someone else gets the same results and can video it.

Hi Jason,
    Thanks for the info, I will try it out as soon as I get a chance. I will try and put a vid up aswell.
Cheers.

Playing with it more.. still a wall  :(

Sorry.. I still would like video of your latest setup.

Thanks,

I noticed you bridged the first gate.. I tried bridging all the gates and gained a lot in acceleration.  Also seemed to reduce the wall.   :)

The only problem with bridging them all is that it comes back after the exit.. Edit: I tried it a few more times.. added more gates and most of the time it was able to pass the exit without coming back.  Very impressed with the acceleration by bridging all the gates..  after playing with these different configurations, I take back about the walls (I didn't have the array perfectly level.. the last two setups were level).. I think the wall is about the same with all the setups I've tried so far.. so the only bonus is the acceleration.  Edit2:  I found that if you bridge all the gates that you can't start in the array.. you have to start at the beginning..  without the bridges you can start anywhere inside of the array.

Hi Jason,
    It is suprising how much difference it makes if it is all on a slope, even just a couple of degrees out can give false results. Keep up the good work .
P.S you can get slightly different results if you replace the BB's with nuts ( as in nuts and bolts )  size m6 and m8 are a couple I have tried, seems to smooth the array out ( i.e no negative spots ) but positive power decreases.

I must be doing something wrong with the setup as my image comes up different

Not sure.. here it is showing polarity.  I don't think having the extensions helped reduce the wall.  I set the magnets strength to 100,000 microTeslas (the max streangth) by right clicking on the magnet and choosing "Change data" from the menu.

@4Tesla

I used 3 shorter segments instead of one long one for the "outriggers", changed it thinking that was my error, but ended up looking the same.  Oh well.

Well that may be why I still get a wall, because I don't have long magnets.. I used two short magnets to make the longer magnet when I tested this setup.  Something to still try if that makes the difference?

Edit.. and it looks like I should have used three.. that could have also been the problem, but I think the reason I still had a wall is because it needs to be one long magnet and not three short magnets stacked.

I don't thing three short mags connected together should make that much difference in vismag as long as they are really butted up to one another. Just a little out can make a difference though.

@all

On a level plain the roller do not quite get thrown clear of the last tri-gate as I said before ( its very close ) but what I did do was to put another MkE array about the same length as the tri-gate array away from the  the last tgate and with very carefull placement ( distance ) the roller could be pulled free of the last tgate and into the MkE array  ;D . Some may say so what, but the cool thing was if you placed the roller at the very point it starts to get pulled into the MkE array and then remove the MkE array the roller do not get pulled back into the tgate Which may mean that there is something going on with the interacting fields ( on a positive side  ??? ). I need to get hold of a longer piece of plexi so I can see ( hope  ??? ) that 3 sets of Kgates will make the roller accelerate, that will be a step in the right direction.

@all
    Well it was a bit of a let down  :( putting a second Kgate after the first showed that it was not going to accelerate. The roller don't get thrown out so far after the second gate. So conclusion is the roller needs to get thrown well clear of the pull back of the last tgate to stand any chance of success. The 3 mags shorting the first  tgate can be removed and do not need to be there they have very little if no effect on performace of the Kgate. I think I'm gonna continue looking at running the roller backwards through the array using a seasaw motion, if this is setup correct it appears that the roller can start on a level plain be puller up a very small incline tip the seasaw and that small decent is enough to brake the wall on the other end and end on the same level as it started and be clear of the pull back in. I need to set this up more accurately just to confirm. I will do a vid with the results when I have the chance.
