Yu oscillating Generator ---- Overunity YOG Model

[Cloxxki]

All very nice and complicated, but the inventor stated that a tail fin would also turn the magnet, at the cost of a bit air drag. If this air drag is less than the array's gain, by all means use that! You get the same weight distribution, just as the cost of a bit of drag, rather than under suspicion of possible gain from the turning device itself.
The gain in the servo assisted video is huge. Seems a smartly cut tail should not spoil that party, if indeed the servo input doesn't enhance the swing significantly now.

   OU could be proved via purely mechanical (tail fin or counter weights to turn the magnets) or electrical (servo).  When electronics come into play watts in vs watts out come into play.  AC readings on output can and probably will make OU a tricky subject until verified by some 'credible' source (it's like groundhogs day on many OU stories which are precipitated by honest misreadings). 

It really depends on how comfortable you are with electronics vs mechanical engineering.  Pick your poison, they both present their own challenges.  Impressed with the mechanical work up to date.  Best of luck.

Synchro1,
I like what you are saying. Flip vertically instead of horizontal. Using a small slotted lever to push/pull forward.
Is it like this? 

The auto door lock pop would probably cut the energy time by 50% or more

There is another possible method that is has been weighing on my mind.
Sometimes called the Smart Alloy, Muscle Wire or Memory Metal, is an alloy that "remembers" it shape. You can reshape the wire, but when temputure is applyed it returns to the preset shape.

Here are some videos of the alloy.

Here you go Howard, how about this:

I am going to add some "colour commentary" for you:

When the mercury switches trigger the solenoids to fire they will rotate the magnet by 180 degrees.  You want to fire the solenoids with just enough energy to make the 180 degree turn and no more than that.  Therefore you want to use a transistor to fire each solenoid where the pulse width is timed by a 555 timer setup.  You can use the CMOS version of the 555 timer and use very small timing capacitors and a very large timing resistors to reduce the power consumption of the 555 timing setup to almost zero.  Therefore the only real energy you will use is to fire the transistor, and you keep the firing time of the pulse to a bare minimum.  The solenoid only has to "launch" the rotating magnet on its trajectory to the opposite depression in the metal plate where it will remain locked in place until the the next half cycle starts and the opposite solenoid does the same thing.  The magnet is basically pseudo "coasting" as it rotates around the 180 degrees.

This is basically a ping-pong game between two solenoids that are the "bats" and the magnet is the "ball."  The game is being played as slowly as possible so as to use the least amount of energy possible.

There is one minor complication related to the sloshing mercury in the mercury switches.  You don't want to accidentally trigger the solenoids twice.  Therefore you need at least three 555 timers, one each to time the pulse for each direction and a third 555 timer that is the "lockout" timer that will prevent any retriggering for about one (?) second once the first trigger fires.  You figure after about one second you are guaranteed the sloshing mercury will not generate a second trigger.

So to do this you need a quad CMOS 555 timer ship and a one or two CMOS flip-flop chips and perhaps a few CMOS logic gates.  Using this setup more than 99.999% of the battery energy will be used to fire the transistors and power the solenoids and less than 0.001% will be used for your timing circuit.  For all of this to work the magnet has to be perfectly balanced in its housing.

To make it as efficient as possible the ends of the solenoid plungers should not have any rubber bumpers on them because the rubber will dissipate energy.

If you have access to a machine shop and know your stuff or know somebody that knows his stuff  the mechanical stuff should be doable.  Drilling a shaft through the center of the magnet should be doable but would have to be done very very slowly, or perhaps you can find a stock magnet that already has a central shaft that is already perfectly balanced.  I am not so sure about the ball bearing setup, it could actually be a small wheel on a good bearing with a spring-loaded fulcrum, or some variation on the theme.  I am not a mechanical guy but I have to assume that somebody would be able to build this without having to go overboard.  If you know about electronics, the timing circuit is trivial and could be breadboarded in a day.

One last thing, you have to drill a shaft that's mirror-image to the shaft that is used to hold the spring-loaded ball bearing.  I did not show that in the drawing.  That's really debatable though.  You could balance the magent some other way if you wanted.

Then there is another interesting school of thought that just occured to me.  You could intentionally keep the magnet unbalanced so that when you are at the end of the swing the magnet wants to "fall" down.  In this case the solenoid will need even less energy when it fires because the magent will "fall" into place and lock after it rotates by 180 degrees.  So in this case you are using gravity to "help" the rotation process along.  In this case you will use less battery energy, with the trade off that you are now drawing some of the gravitational potential energy out of the pendulum.  Every time the magent is "released" by the solenoid and "falls" into the opposite 180 drgree position, you are lowering the center of gravity of the magent system but just a tiny bit - and that represents sucking some energy out of the pendulum.

Just adding a few more thoughts.  Something similar to what I am describing probably already exists in real life as an off the shelf part.  It would be some sort of mounting for something that will "click" in one of two positions that are 180 degrees apart.  Some sort of an actutator system that would be used in factory automation or process control.  The finer and more delicate the mechanism, then chances are the more expensive it will get.  Something that you could simply mount your magnet on top of and then build something to hold the solenoids in place, etc.  With enough Google searching, you could probably find something that will work.

An off the shelf part may have some sort of spring tension mechanism so that you could adjust the "stickyness" for when the setup clicks into place.  You need just enough "stickyness" so that the magnet will not "unstick" itself as it experiences torque as it passes through the array.  The lower the "stickyness" setting, the less energy you have to put into the solenoid to "launch" the magent through its 180 degree rotation.

My original point still stands, when the magnet rotates it will be fighting against the external magnetic field from the array and a little bit of energy will have to be expended to do this.

Also, every time the magnet rotates, you are expending energy to "launch" it and put rotational energy into the mass of the magnet.  When the magnet "lands" in the depression 180 degrees away, this rotational energy is lost forever.  Therefore in theory you would like the magnet to rotate as slowly as possible to reduce the amount of energy lost for this step in the process.

Ultimately you could tune all of the paramaters just right so the minimum amount of energy is expended to do the 180 degree rotation.

Good stuff MH.

Howard,

Reluctance to perform a test without the magnet array is either out of fear, or arrogance, or a combination of both. That's pure emotion--it's not science.

Please set your emotions aside for a brief moment and consider running a test without the array present to observe how it behaves. That would be science. Surely you must also be curious?

Give it a go--the worst that can happen is you gain more insight into the various interactions going on
