Hi TinselKoala,

Never heard of the term "Fire 2.0??"

Up to this point I really never made any SMOT devices but I knew a little about them.

 Tom, make sure you sand the edge of the transition ramp in to the curve so there is as less resistance as possible when the ball is entering the curve. If it has the slightest bit of a bump, it will be a resistance which will take away from the speed of the balls forward motion.
 It would also be good to see what the field looks like in the corners by using a magnetic field viewer and then create a curve based on what is seen.

Tom, did you notice TinselKoala's profile picture? It sure is a good concept that would only need the magnets special made to be like your concept but round instead of square.

Won't roll all the way around, either!

(Don't get mad, just prove me wrong!!)

 Well it will not with Toms set up the way it is but it will and does when the magnets are arranged differently. I started at the beginning of one straight a away and I have made it go completely around the curve to the next straight a way and then all the way down to the end where the next curve will start but I need more of the same magnets to go any further. I am not sure what is going to happen when I close the loop but I do know that the corners are not a problem to get around. I will post a video as soon as I add more magnets.

Hi Guys,

The way I see this is the long straightaway is the key in the design.  Its a must that the steel ball reach a certain velocity so it could have the needed energy to go around the curve. Or for that matter shoot off a tracks end if you are working with a single track segment as a startIng point.

The weight and size of the steel ball has to be taken into consideration also. An iron ball would be the best material to use.  I was using chromium steel bearings. The track walls and floor could be made of teflon which presents lowest friction characteristics.  My floor is rough plywood right now and the ball rolls.

I found that in the corner areas there is great attraction ( NO STICKY SPOT) to keep the ball from rolling onto the next track segment. If a very small magnetic track segment was made and placed in the long track corner areas at a 45 degree angle maybe the ball could pass over it and enter the other long track straightaway for another go around.

Tom, I just got home and I am now on my way to get the other magnets I need. The setup I put together is a U shape and the ball does not have to be at the start of the long rail, it even works from the start of the curve. I am having doubts about it working after I close the loop but that ok if it doesn't because I have enough now to take a ball over the top to make a gravity design work. Thank you for starting this thread and sharing your findings with us. If this works as I hope it to, I owe it all to you.

 I will post more with pictures when I get back and add more magnets to the setup.

Hi Nightlife,

I am extremely interested and excited  in how you made the magnetic U turn.  The track magnetic structure did not allow any air gaps between them so that dictated using a straight linear run.  I would love to see the jpeg layout of your track and especially your U turn magnet configuration.    Wow!

On most other tracks when you close the loop all track runner power dissapears.  With 4 track rail segments butting up to one another that problem did not occur for me.   In a long straight run with two U turns ending with a closed loop who knows?  I hope everything works out for you and you post all.

“How many folks are in the process of actually building this setup to give it a try?...
 After lots of experimenting I found that placing a large steel ball inside the square rail box will propel it
- Yes, I've tried.
Yes, that’s what I thought too – there’s no difference, rotor or ball.
But unfortunately there’s no rotation because loop of magnetic field is closed.
The same with one  magnet in rotor.
Will try with 5, hope will see any difference…
cheers

You are obviously using the wrong colors. Try getting some blues and browns in there.

Every working SMOT I've ever seen had blues as well as reds.

No, wait, I almost forgot--

There are (still) no working SMOTs !!

magnetman12003, I am curious to know what you think the problem was with Archer Quinn's various designs. What did he do wrong, that prevented his "sword of god" magnet wheel from working, and also his various SMOT attempts? Did he not have enough magnets, or not a long enough track, or what?

I did exactly what you did --see reply 42. The round plastic frame inside the tracks wont work. The ball has to roll on the strait section of the track for awhile  to gather up speed .

If only colors could make it run :)…

Yes, speed or shield. Maybe longer track will do the trick…
But again, "strait section" has open ends - magnetic "stream"; loop closed - no gradient, no movement...

But this (attach) magnetic gyro seems spinning a little longer than without this stator; maybe because all field around is equal.

Here is a video of the U shaped array I was talking about. It would work better if I had the magnets perfectly aligned and if the track was in better shape. I used 1/4 neo disc in sets of arrays of 4.disc per set. I do plan on doing more testing with this concept coupled with gravity.

Hi Light and welcome to the madness.

 Good job on your box and I look forward to seeing more of your work.

@all

Does anybody knows the whereabouts of a video that showed a washer rotaing in a magnetic field over an acrilic at great speeds?
It was on youtube, I watched it and was looking for it to post its link here as a contribution to the thread, but I could not find it again.
It is a circle of magnets like hamels, but instead of a magnet at the center, there was a steel washer. The circle of magnets was stationary and the washer was spinning at agreat speed on the center over an acrilic plate.

Hi Nightlife,

Awsome video, 

Thats proof that a U curve can be made that will allow a steel ball to roll around easily.

Did you use a steel strip insert on the tracks insides to keep the tracks U shape?   Can you draw out the magnet arrangement you used on the tracks U curve and post it?

I see you noted closing the loop stops action. No problem here either as this track is powerful enough to power a steel ball up a grade as I have found by experimenting.   So when the steel ball is close to the end of an inclined grade at some point the ball can fall through a hole in the tracks bottom to start its journey once more on the track below it.  -- No closed loop.

I am fresh out of block magnets right now but I do have about 2,000 ceramic 1 inch by 1/4 inch thick DISK magnets I might try.  I never thought disks would work.   Arranging them at 45 degree angles is going to be a horror story.
