He now says it is fake with batteries:

Yea, this guy, I dunno.

First, like said already above, those bolt heads would have to have been lathed hollow and probably the nut with the bolt screwed to it to fit that battery in there.

And why not show the actual battery if the battery is short enough to fit between the cutoffs of the head and nut of the fake bolt?

Also, when he shows the rotor spinning in one direction, the led's are dim, but in the other direction they are bright. With a battery, the led's should light where ever the magnet is, as long as the coil gets juice from the reed closing, the led's should light during the coil collapse when the reed opens. If there is a battery

If he would have pulled the hollowed out bolt cap off of one of those coils, I wouldnt be writing this.

The schematic is correct as in the led's will only light when there is coil collapse.

But I wanna see the coil taken apart to see that battery, the battery he shows in the vid. I realize that the wire is supposedly wound around the battery, but just leme see the top or bottom of the battery in one of those coils.

Dang, its hard to believe and admitted faker.  lol   Cant even get that right.

This bit I know: Sometimes we believe what we want to believe.

The bit I don't understand is grown up people behaving like juveniles even if they admit to their deeds.

I have come up with a method to make a standard "toy"
DC motor like one might build oneself that has a special
2 part commutator. Basically it uses an optical disk and
H-Bridge to control the field current direction based on
the rotor phase and then logically "nands in" a N.C. normally
closed reed switch position detector mounted on an
adjustable spatula like he has.
 
The concept is that you build this DC motor first and get
it to run. Then once it runs remove the applied DC field current
and rewire the field circuit it to what he said he had. The
operational parameters should be pretty much the same
between the two putative motor operating modes.

The thing is that a pure magnetic motor versus a dc motor
with no commutative field current reversal should operate
using iddedic methods. That is if you can build a commutatorless
DC motor you will also be able to build a pure magnetic motor.
 
The way it would work is that a shorted field coil with a low resistance
shunt would allow rotor magnets to intrude with only true LENZ braking
losses then when the coil is unshorted the rotor poles suddenly see each
other through the now in-series field coils.

If I had this to do fake It might require a Bedini mirror circuit inside each or one
field coils along with the battery - the reed switch could then be fake inoperative.
Also the faces "N" and "S" marked in ink on the magnets might lie. The reed switch
would work if the postion of the rotor magnets was always "N" incomming.

He must show the coil with the battery and the resistor inside to clear things up, in his schema the battery is shorted with the coil, but maybe if the reed is closed and opened, the coil in series with the battery will produce a kick that turns the magnet rotor, but how did the led survive the hv inductive spike? or the battery is regulating the voltage?

Well according to the diagram, it looks like he soldered one of the leads of the coil to the batteries casing(-) near the positive terminal. Like he removed some of the wrapping that covers the battery. So it is in series with the coil and resistor.

Also hiding the resistor with the battery means even more space needed in the cavity of the coil. The coil doesnt look lumped like it is beside the battery, so it must be top or bottom.

Im getting on the bench now to try to see if the led lights. Just a simple circuit, no motor.  Was going to do it last night but got distracted with other things.

I need to see the led light. If it does, then there is a reversal of magnetic field before a reversal of current flows.

Check any literature on switching power supplies. During the field collapse when input is disconnected from the inductor, current always flows in the same direction as the input produced through the inductor. Not reverse emf. Not back emf. But a continued forward current.

Mile High and I had discussed this at OUR when he put us "pulse motor builders" to a test of figuring out what was going on in a particular motor circuit.

Well I did describe what I thought. I also did not know which polarity of the output capture diode was in the circuit, yet I claimed also that the diode could be set as either polarity and the capture capacitor would still see a higher than source voltage, because of field reversal that can happen if there is no load during the first collapse.

If the capture diode is in a position that current from the source IS directed to the output cap, there is still additional currents from the collapse and reversal happening anyways.

So I need to try it in this case to see if the reversal happens, as I have seen before, just not the way this guy does it with the battery in series with the current from field collapse. But If it does, then my my description to mile high is correct, but he did not agree. Nor did he explain why. ;]

When I first discovered it, I didnt know what was happening at first.  It was when I was running a second pulse motor stage with stored collapse energy from the first stage. The diode could be in either direction and the second stage cap was getting higher than source, but a different polarity than normal collapse capture. But I did find that the source would send additional power to the second stage if the diode was set to do so. But I remember specifically to use the diodes polarity so that the source did not make it to the second stage storage cap directly. Or else others might say that the source was powering the second stage also, not just the first.  Even if the timing were set differently between the first and second stage. ;] 

All coils have some capacitance. So a coil in itself can oscillate. In a regular coil,not bifi, etc, the freq of oscillation would be very high due to very low capacitance distributed throughout the coil windings. A bifi will have much greater capacitance thus lower oscillation freq. So even with a regular coil, the field can reverse if there is no load to stop it from happening via damping due to the load.  Like loading an LC while ringing. It will kill the ringing.

Even in Falstads circuit sim, you can apply a scope shot of a coil, and if disconnected from a source, with no direction for current to flow in either direction, the coil will self oscillate at very high freq. ;]

One thing that intrigues me is, can we use this field reversal to our advantage. ;]  Always thinkin. Even with ideas from possible fakes. ;]

Thanks Bob

There is always something to learn. The circuit is unusual.  If you read my last post in the This Might Blow Your Mind   thread, this circuit in the reveal of the fake simplifies the Ossie circuit to get the collapse back to the battery with only 1 reed, not 2. I describe it there. ;]

The guy that did the clip made a mistake in his circuit because it makes no sense.

However, if you move the two batteries around then it's just the same old circuit that makes the LEDs blink when reed switch opens.

reed switch bottom ->  batt negative -> batt positive -> 5-ohm resistor -> coil -> reed switch top.

If you can look at the diagram in the YT clip and follow the above then you will see how each battery would be placed in the bottom horizontal connection line in the schematic.

Relative to the corrected schematic, when the reed closes the current flows up through each coil (remember the batteries have moved) and the current flows down through the reed switch in the center.

When the reed switch opens the current continues flowing up through the coils but now it flows down through the LEDs to complete the circuit.

There is no high-voltage spike at all.

You notice that even though the batteries have been moved, the 5-ohm resistor is still soldered to the positive terminal of each battery.  So it's conceivable that he got mixed up when he made his schematic.

I just put a sim circuit up that shows the reversal of current(actual bemf). And it works in the real world.

I suspected that the circuit was not correct also at one point, but I remembered that reversal can happen. In that circuit, the leds wont conduct if the current continues to flow in the same direction from the coil. The cathode would have to be on the top side of the led(diode) for current to flow as you say. And if you flip the led that way, the led would just drain the battery at all times, except when the reed is closed.

Look at the sim with codes above. Actually, make the circuit for real. Either way I am right. ;]  I just proved it.

I explained this to you at our. But you didnt agree then either. ;[

The larsko circuit works as shown. Its just not a common situation. It had me going for a bit also, till I did something about it and tried and proved. ;]

Its simple. If I have to make a vid.....

He just posted a third video with a wrong circuit diagramm...

http://www.youtube.com/watch?v=fM6-4D74bi4

 This way the circuit is drawn, the LEDs DO NOT light up due to the BackEMF pulse !
He just shorted out the LEDs with the Reed switch !!
If he wanted to pull a prank he should be able to draw a correct circuit diagramm...
Also it would be nice if he would have  dismantled the motor to show the hidden batteries inside the coils...
Otherwise people might not believe him as the batteries looked too long to fit inside the coils...


Also User Mopozco has made a video about it:

Here is the wrong circuit diagramm from Larsko quickly drawn just one coil leg...
