Confirmation of OU devices and claims

[Void]

Hello All.
I've been busy reinforcing the device and making a new commutator. I used a low viscosity Epoxy resin that has taken over three days to fully cure.
An old boss of mine kindly donated a brand new 10 AH LA motorcycle battery and another former employer gave me a new DMM.
If all goes well with the machining of the commutator today I hope to show you all our progress.
Cheers Graham.

Hi Grum. Sounds good.

About pulsing 12v set up coils. Try using 1uf -10uf 400-600v for the capacitor being charge, and connect a bulb to it. We found some result with the same set up on coil but different types of capacitor being charge. 12v power input. on 10,000uf 4v is the only charge we get. On a 4uf capacitor we get 400v which could light  a build if the pulse on the coils are continued. We found that when we charge e.g. 10,000uf or 4700uf the charge are being converted to lower voltage let say 4v, which eventually dies out  and can not sustain the system.  But with 1uf -10uf 400-600v with just 1 pulse bulb could be lit continuously as long u give it a pulse. With lower UF capacitor we get higher voltage, and the voltage can make the system sustain.

Hi stupify12. Yes, I have been testing with different cap sizes and different switching rates
and different pulse widths and that sort of thing, but I am using solid state switching with
no motor and generator. If a motor/generator using a big flywheel is key to getting unusual
results, then I wouldn't see that in my tests.


Here are the results of one of my tests from yesterday in which I was using a small 5AH
SLA battery. I was pulsing the battery through a coil wound on a laminated steel core in this
test. My analog DC ammeter showed I was pulling a continuous average current of about 0.5A
from the 5AH battery for the whole 7 hour test run (my scope current probe showed an RMS
current of about 0.6A), and in this case feeding back pulses to the battery during the battery pulse
off time, and the little 5AH battery was still at 12.44V after 7 hours of continuously pulling 0.5A average
off it. It would appear that the pulses I was feeding back to the battery were being absorbed to some extent
by the battery, as the little 5AH battery was only dropping about 0.01V to 0.02V every half an hour, however
as can be seen in the attached graph the battery was still steadily dropping in voltage over the 7 hour test run
I did.

In this case there was no load connected to the test setup. I was just pulling current off the battery
in pulses and feeding pulses back to the battery during the battery switching off times. I will
probably continue to do some more tests with solid state switching using different configurations and settings
to see if I can see anything unusual. In tests I did where I was pulling only a small average current off the
5AH battery in the low mA range and feeding back pulses, the battery seemed to be able to hold at a steady charge,
although I didn't do a really long test run at that low current draw rate, but that is at a low current draw rate with
no load connected, so not very useful.

All the best...

Nice work Void, it's always good to have graphs.

But...it would be even nicer if you could do a comparison. Take two identical batteries, charge them both equally (charge each first, then connect in parallel and let sit for a while to equalize). Then connect one to the system you used to get the data for the above graph, and connect the other to an ordinary resistive load that will give you the same average current draw. Plot voltage vs time as you have done but for both batteries so the discharge curves can be compared.

Hi TK. Yes, I have thought of doing that if warranted (having a control setup to compare to), but in that test the battery
voltage was not holding so I didn't think it was worth the effort. However, if you take into account the Amp-hour
rating of the battery (5Ah), and consider that I was pulling approx. 0.5Amps average continuously for close to 7 hours,
then it appears that the pulses that I was feeding back in a closed loop back to the battery were helping
to keep the battery discharge rate slower than would be expected. At the rate it was discharging, it looks like
the battery might have been at around 12.32V or so at the 10 hour mark, if the discharge rate would have continued
at about the same rate for a further 3 hours. However, without feedback, after 10 hours the battery should have been about fully
discharged based on the 5Ah rating, so I would expect the battery would drop to around 11.8V or lower after 10 hours.
The results I saw were nothing too unusual though I think, as I was feeding back energy in pulses back to the battery
in a closed loop, so I would expect that it would slow down the battery discharge rate.

All the best...

Here are some results from another preliminary lower power battery pulsing test I am currently running.
Same type of 5Ah battery. Start voltage for this test was about 12.98V because I had
run a few short tests with a different setup with the same battery just before starting this new test.
(This SLA battery's unloaded terminal voltage when fully charged sits around 13.10V or so).
The battery voltage rose a bit to about 13.03V/13.04V after starting the test.

I started out pulsing the battery with 8ms width pulses which pulled current pulses from the
battery at about 340mA peak as measured with my scope current probe.  However, the pulsing frequency
is 1Hz, so the average current draw from the battery is in the low mA range, such as roughly maybe
50mA average or so, or maybe even less.  I am pulsing the current from the battery through the primary
winding of an AC transformer (to take the place of the winding for a DC motor or pulse motor).

In this test I am also pulsing a small 0.6W neon bulb as a small load with each pulse.  It is interesting
that although in the first hour I was pulling current pulses from the 5Ah battery at about 340mA peak,
once per second, the battery voltage stayed right around 13.03V to 13.04V for the full first hour of running.
The only current that I am feeding back to the battery is through the neon bulb load, making use of the
switching spikes to flash the neon bulb. I am not charging and discharging a capacitor in this test.

After a few hours I reduced the pulse width to about 5ms (from 8ms) as I noticed the battery voltage was
starting to drop a little bit (down to about 13.01V/13.02V). This setup has now been running for over 5 hours
and the battery voltage is now at around 13.00V, so it has only dropped about 0.03V or 0.04V after pulsing for more than
5 hours. Not too surprising I suppose since the average current draw from the battery is not very high
compared to the battery's current capacity, but I think it shows some potential. With some further fiddling 
to improve the energy recovery I may be able to get it better. Once I have it as good as I can get it, I may try to scale
it up to higher power with a larger battery to see how the battery voltage holds up while drawing much higher current pulses.
I am still working on ways to improve the energy recovery, so this is still preliminary.

Here's a very short video clip showing the transformer I am using for the coil, and showing the
pulsing of the small neon bulb load. It is not flashing quite as bright now since I lowered the the
pulse width to about 5ms after a few hours of running, but it is still flashing fairly bright. I will leave
it running until tomorrow to see how the battery voltage  holds up. It seems to be very slowly discharging
the battery though, so it will probably continue slowly discharging over night. No magic happening yet.
Short video clip:

(The analog ammeter seen in the video can't respond fast enough to show the true current peaks).

I have attached a scope shot showing the current pulses from the battery when
the pulse width was set to 8ms. With the pulse width set to 5ms, the current pulses from
the battery are peaking at about 250mA.

P.S. I am driving the gate of a MOSFET from a signal generator, so the switching circuit is not
being powered from the battery in this test. If it was, the battery voltage would no doubt be
dropping more quickly. Charging caps draws more energy from the battery as well, so you are
going to need to find a fairly sizable energy gain somewhere if you want to run the control circuitry
from the battery and keep the battery charged up all the time as well. Maybe the big flywheel
with a motor/generator setup and the alternating pulsing while coasting with the flywheel can
add something special into the mix.

All the best...

Well,after many hours work,and keeping as close as i could to Johns spec's on the 1985 energizer,--err 

Will not be wasting any more of my time on this heap of garbage.

Back to the big one,which has some sort of chance of working,
