@ Hoppy:

Thank you for your sincere and intelligent reply.  Actually, as I have stated on OUdot com many times, I don't really believe in OU.  Nature loves equilibrium and unity so, I think we have to be happy with that.  The fact that someone can run something at X input and get 2 X out of it just tells me that we don't really know where the other input is coming from, but, it is coming from somewhere.  This is just my opinion.

The main problem I see with actual replication on this, and other, sites is....lack of finances.  Heck, I just got another computer out of the dumpster at my apartment complex and I know there are things I can use out of it. (and I will)  Take the Joule thief topic for example.  I started that topic and have posted 19 videos on youtube on my work there.  I too have had folks that said....well I did not have the 3904 transistor so I used something else, and I did not have a ferrite toroid so I used something else, and I did not have the 1k resistor so I used a 2k resistor instead and.....your device does not work at all!!!!

This can be very frustrating to say the least.  And yes, wire size, transistors, capacitors, and all other components are all variables on this stuff.  My way of replicating is to build it exactly like someone else did and then....tweak a little here and there and hopefully get better results. (sometimes not)

Anyway, I can tell you and I are both on the same wavelength here so I will shut up now.  Thanks again for your very respectful and intelligent response to my post.

Bill

Hi,

Attached is my newest circuit drawing for my two coil pulse motor/charger.

I use one FGS 12V 7A GEL (drained) battery as a input. Battery voltage is 9,24V.
On the output I have a similar battery. This was also drained (10,5v) but has climbed
to 11,25 volt during the last couple of hours. My design goal was to try to mix some DC
current through the coil with the AC current in the coils. I have tried to measure
both the input current and the output current. My moving Iron meter shows no sign of input
current. (Although there must be some small current flowing.) The moving Iron meter shows
a very very very little output current. I do not know how big it is but I do know it is bigger
than the input current because the needle has moved a tiny bit upwards! You can draw
your own conclusions since you already know the output voltage to be bigger than the input voltage.
I'm NOT claiming any o/u yet because there is difficulties doing an accurate measurements when
the currents are very low.

Hi,

Here is my solid state variant. One battery connected.
If the battery is charging then o/u else not.

I can see the circuit is oscillating by a dim light in the Neon bulb.

Battery start voltage: 10,32V

Circuit drops the battery voltage to 10,28 when first connected.
Then battery gains 0,01 voltage approximately each 1/2 hour. (So far.)
Battery has gained voltage to 10,30 after 1 hour of running.

I will keep this circuit running and report back in some hours.

[EDIT-1] Circuit has been running for two hours now. Neon bulb still glowing dim. Battery voltage 10,32 Volt.
[EDIT-2] Circuit has been running for three hours now. Neon bulb still glowing dim. Battery voltage 10,32 Volt.
             Seems that the voltage increase is leveling out now. No gain in one hour.

Groundloop.

@groundloop:
There is something about this circuit I don't understand.
Back EMF is caused by switching off the transistor after being on.
That causes the bottom of L2 to have high voltage.
That would mean current is pushed into the minus pole of the battery.
Which means discharging the battery after already being discharged while the transistor is switched on.
What is wrong with this analysis?

Note: assuming the red pole of the battery is the + pole

Hi robbie47,

I'm not sure I understand this circuit myself. :-)

The circuit IS oscillating. I can see that a high voltage is created that light the small 65
volt Neon bulb. The coils is connected so that when the transistor is conducting current
through L2 then the magnetic field hits L1 and brings the base low, thus shutting off the
transistor. Then the L1 flips around and triggering the transistor again. The diode chain will
drop the voltage input on the collector by approx. 5,4 volt. That way the single diode is free
to conduct current to the battery. This will happen because the current always goes the
path of low resistance. The circuit has back emf voltages of approx. 65 volt. Because of
the single diode the L2 coil can only push a charge into the battery by the negative terminal, I think?

If there is someone out there that have another explanation, please correct me. All I know is that
the oscillator is running and the battery has gained voltage. It MAY just be that the voltage pulses
eliminates sulfur buildup on the battery lead plates, thus we see a gain in voltage.

Close to 4 hours run and the battery voltage is: 10,33

@Groundloop:
Great results!
If the neon is lighting up, this means the emitter of the transistor is at high volts (> 65 Volts) at some time in the oscillation.
Are you sure you have drawn the coils correctly in the above circuit?

@robbie47,

Yes, the coils is connected as shown in the circuit. The solid state is the same as my motor. I have
just stopped the rotor. See earlier post on how the motor looks like. The rotor is from a computer fan.
I have removed the fan blades, the electronic and the rubber magnet inside the fan hub. I have NOT
removed the iron ring inside the fan hub. Then I epoxy on two Neo magnets.

Edit-1 Added some images. You can see the neon bulb glowing. Also remark that both pins in the
          neon bulb is glowing. This means that the voltage over the bulb is AC.

@groundloop:
OK, thanks for your confirmation and the pictures!!.
I really want to replicate this if your battery continues to charge.

[deleted].
[Edit] From the pictures I understand that you are using the bottom coils, which is a bifilor wounded one?

Any idea what the oscillation frequency is of this setup?

@robbie47,

Yes, it seems that the iron metal ring inside the plastic hub is the magnetic link between the coils.

My coil are wound onto two plastic bobbins measuring 47mm diameter, 18mm thick, 15mm center
hole. The spools are approx. 80% full. I did use 0,25mm enameled copper wire. The DC Ohm on
each coil is approx. 48 Ohm. The distance between the coils is 52mm. Neo magnets is grade 35
and are round 14mm diameter and 8mm thick. One magnet has North out the other South out.
Rotor and coils are epoxy glued to a plastic box. The magnets are epoxy glued to the rotor.

Both coil is SINGLE wound. Two separate wound coils.

My frequency counter says 48,9 kHz.

@groundloop:
Thanks for correcting me on the coils and sharing all the details!

Your ventilator components wonders me.
I am used to having a magnetic ring inside the 12V ventilators I am using.
The cores of the 4 coils inside are independent and isolated from each other.
You must have a different ventilator type there, since you talked about rubbery magnets inside that you removed.
Does that mean the coils inside this ventilator unit are all mounted on the metal ring?

@robbie47,

No. I only use the fan rotor. I have removed ALL coils and pcb inside the fan. Then I cut the
four legs to the fan housing. I cut off all the fan blades and use a little sand paper to get
rid of the fans remains. I take out the circular rubber magnet inside the hub but leave the
iron ring because it is difficult to remove the iron ring without damaging the hub. Then I glue
two magnets on the outside of the hub. Now I have a two ball bearing rotor that spins
very freely. The only coils is the one you see glued to the plastic box. The fan was a 80mmx80mm
computer fan.

Edit-1 Added a scope shot of the oscillator. (Use hand held camera so quality is not very good.)

@groundloop,
Thanks again for the details of the rotor.
So, basically the rotor is not moving in your present setup?
What is the position of the neo's towards the coils you use? Are they facing the coils or 90 degrees rotated from the coil entries?

@robbie47,

No the rotor is stopped by hand. The rotor align itself North / South because of the low friction in the bearings.
The oscillation starts by itself when I flip the rotor a couple of times. This to trigger the L1 coil. Then I stop the rotor.
Then I adjust the variable resistor to highest value without the oscillator stopping to run. The oscillator will run when
adjusted so 10K is in series with the base of the transistor. I maybe fit an extra resistor later on.

The battery voltage is now: 10,34

I will run this circuit through the night to see what the voltage is in approx. 8 hours from now.

@groundloop,
The oscilloscoop pictures helps a lot understanding the circuit.
It seems you measured it with the probe AC coupled?
