@ magnetman (and anyone else attempting to build this setup)

be very careful when playing with the "butterfly" effect as you guys are calling it.
ALWAYS ALWAYS have some sort of "brake" or wheel stopper, if you lock this thing into fixed oscillations in the right configuration it can accelerate exponentially, ( means it will spin faster and faster until it tears itself apart)
and pieces can go flying around the room at dangerous speeds.

you're not quite there yet, but this approach you're taking here is getting close to a fixed magnetic oscillator, and should be treated with caution.

im not by any means attempting to discourage you from your efforts, im just saying to be careful, i had no idea such a thing was even possible until i nearly killed myself, scared the wife and put holes in the walls from flying magnets!!!! 

the system i had fed off of each other, which is what i think you're trying to do with the "swivel" magnet on the stand???

with this kind of spinner i dont think you have to worry because the ball will just break free from the magnetic field and start to slow back down, but if you fix the spinner this "failsafe" goes away, and opens the door for a potential runaway.

just thought i'd throw that out there, 

----------------------------------------------------------------------------
as far as attaching a pendulum to the spinning disk.....

there are so many sides to that i dont even know where to begin..

so i guess first lets start with the action of the pendulum while its spinning.

im assuming the disk is spinning at a considerable rpm, so the pendulum i believe would not "swing" at all, but just spin with the disk.

if its paramagnetic it may be attracted to the disk, wich will have an effect on the entire system, if its a nonmagnetic metal, there will be all kinds of "eddy currents".

so said pendulum would be best to be made of a plastic or other nonmetal materials.

of course, for the pendulum to swing, i cannot be spinning faster than a predetermined rate directly proportional to its mass, or as stated above it will not "swing", so attached to a slow moving disk nonmagnetic metals could be used. 

secondly i shall address the "kick" you which to achieve from the slowly spinning pendulum -

though most concievable attachments, the force you willl achieve is verticle.
or would otherwise hinder the action of the pendulum.
this verticle (downwards) force could be used to offset the balance of the (slowly) spinning disk.
perhaps through this you could maintain the disks motion.

i am unsure how to impart the force back to the pendulum - [if anyone has some insight on that it would go great with my perpetual milkovic hammer idea...].

also not sure if the "slow spin" is even workable in this type of spinner??
a fast spinning disk would surely impart forces into pendulum that would prevent it from swinging.

-- IF the pendulum is not spinning with the disk, but rather attached to the plane the disk spins on, then a fast spinning disk could work, provided the plane was allowed to swivel from the verticle force imparted on it by the pendulum.

[ sorry for the long run-on post, i could expand on this for days from so many angles, but i think it would drive all interest out of the entire subject, so i'll leave you guys with this little piece of my thoughts for now]

Hi Smoky2,

Presently I am using a regular Hamel spinner. The smaller ring magnet with steel ball setup.  No disk magnet spinner setup presently since this is working out real well.

The spinner itself spins real fast while all the while its traveling in a perfect 9 inch circle. Thats why I can cut a center hole in the level table its on and it will spin in a complete circle around and around that center hole. The center hole allows the pendulum arm to swing side to side.  Real sweet setup so far.  If the spinner shoots the off its table later for any reason I will slow the pendulum arm down by adjusting weight and lenght. Have not got to that point yet. Thanks for the heads up.
  No ferrous metals used in the entire construction except a 316 stainless steel non magnetic T NUT  is used to secure the pendulum arm to the large ring magnets tilt table Y yoke.

Hi All,

An Update:

I just finished making and installing the table for the spinner with a hole in the center. The hole has to be large enough so that the pendulum arm can swing free allowing the spinner to travel around it.

To small a hole and you wont be able to tip the large ring magnet balance beam head to allow the spinner to move.

To large a hole presents a problem of tipping the large ring magnets balance beams head to much. This allows the spinner to fly upwards to the large ring by attraction. Both magnets could be damaged by this action. Also the spinner might fall through this hole by accident.

All this is very important. Keep everything LEVEL as you construct this device.  A good bubble level is a necessity.

Right now I am adjusting the weight at the end of the pendulum. If you allow this weight to go to articulate fast you will see the spinner spin in an ever and ever larger circle untill its magnetic fields break free and it flys off the table. That happened to me already but I was prepared and expected that.

By adjusting the weight at the end of the pendulum I hope to reach a point that the pendulums weight regulates the spinner travel. The spinners ever changing weight as it travels around under the ring magnet  then controlls pendulum movement. Hopefully I can reach a state of hands off self sustained motion. Not there yet.

Remember as the spinner travels under the large ring magnet it is lifted up moreso at different points in its circular table travel by the large ring magnet.
In other words the large ring magnet now holds a large part of the spinners weigh making the spinner itself lighter at that particular point in its circular travel.  You wont actually see that weight shift by looking at the spinner while its moving around but the pendulum action feels the weight shift.

Thats what makes this device so interesting.  Movie to come later.

Hi All,

I have constructed a finished and painted duplicate model of what I have made so far. For anyone that does not have the time, patience, tools, or ability to construct this device checkout my Ebay auction # 110212978123 What you see on the auction page is now painted and has the spinner table attached. The spinner spins on its table.

Please remember that presently this device can be operated using one finger.  It is not self powered yet.  Thats for you to experiment further with as I am doing.

hey Tom,

Great work !!  i love the You-Tube video

i just made one with a 1-inch ball bearing and a microwave magnet !
