I was starting to doubt my oscilloscope because I keep seeing
this odd thing where the power levels suddenly jump and stay there
for a while ... and then start to go unstable ... and jump back
down to the way they where. I've been seeing this
on the amplitudes of sine waves ... but in this video I capture
the same sort of thing in the X-Y mode of the scope.
Just to rule out that my scope or something I'm doing is causing this,
it would be good if others could try to reproduce this observation.
One thing I have noticed is that the scope probes STEAL energy
from the Bashar STA. Anything coming in contact with it will
PULL power from it ... making measurement a challenge
on these big AIR coils.

I have a question about the formula for resonance for LRC circuits.
Here is the question.
The equation:
Fr = 1. / (2.*PI*sqrt(L*C))
is the formula for when L & R are in series. Note that R
plays no role.
For parallel resonance we have:
Fr = (1. / (2.*PI*sqrt(L*C)) ) * sqrt(1. - R * R * C / L);
Hence R does play a role in reducing the resonant frequency lower.
The QUESTION:
What if the value for R * R * C / L is greater than or equal to 1.?
Clearly it can be ... and clearly this formula fails.
I know the answer is probably to use calculus.
Are any of you familiar with how to solve for this?
If R * R * C / L == 1, this would imply that Fr goes to zero.
When > 1, we enter the realm of square rooting negative numbers
resulting in a strange TWEAK to the resonant frequency.
I suppose it would start to RISE again above zero in a parabolic
way ... but it is probably not that simple.
Its interesting to contemplate what occurs when the MATH
doesn't work using these simplified EM theory math equations.
-- update --
OK, I tinkered with this a bit ... putting a variable resistor in series with the coil,
and a cap across both of them. As the resistance starts to go higher, at some
point the circuit ignores the coil ... and the current takes the capacitor path only.
The coil is effectively switched OUT of the circuit.
I've been experimenting with the Super Joule Thief circuit and the Bashar STA,
and I may now have some modest battery charging happening.
I have to study this more ... but it certainly is interesting.
I modified the circuit from the one I just showed in the previous video in
the following way.
For PNP, I used 2N3906.
For NPN, I used 2N3055.
LRC circuit is Bashar STA as coil, 2.7nf CAP (or there about),
and 100k Ohm resistor (1/4 watt).
I moved the variable resistor (POT) across the BASE of the PNP,
so that I could carefully adjust the input level to that sensitive
transistor. No need for a power transistor here as this one serves
as the first waveform inversion -- feedback path.
Battery changed to a "almost dead" 12V sealed lead acid battery.
A heat sink is required -- recommended on the 2N3055.
The POT offers an interesting way to TUNE up and down
the linear curve of that PNP ... and there are some spots
of interest .. depending upon how dead your battery is.
You can use batteries in the range of 1v to 12v here ...
although the more voltage, the more pronounced the effect.
Low voltages probably require smaller transistors..
and greater care in resistive losses.
Remove the LEDs ... and place a DIODE that takes back EMF
from NEGATIVE to POSITIVE across battery ... such that any back
emf from Bashar STA will essentially "charge" the battery.
With the POT, I can dial around and produce a sort of
saw tooth charge pulse to the battery .. using the back EMF.
Interestingly, the Bashar STA receives a bit of extra energy
due to reception of events ... and does a better job receiving
when it is pulsed regularly.
I imagine what happens is that there is sort of a cork-screw
back and forth magnetic field created with the pulsing flux ...
and this field is subject to PRESSURE from the environment.
Its like a vibrating spring with lots of tension ... and as
little bumps and jars happen due to incoming events, it
wiggles back into the oscillator circuit and produces a slight
extra amount of current INTO the battery.
The charging is slow slow slow ... but this may be
demonstrating a principal that can be refined.
I am finding this is a bit tricky to balance ... because the slightest
miss tuning ... can cause the battery to DRAIN .. and not charge.
This approach is reminiscent of the so called "scalar wave battery charger",
only I am using a LARGE air coil which is not subject to the losses
that occur in ferromagnetic coils.
I have more to go here to better understand this ... but wanted
to pass immediately to anyone interested these early findings.
Absolutely excellent. I bet if you pulsed it at some harmonic of one of the fundamental oscillations in the earth's magnetic field it would draw the most power from space-time. Also, the transistors getting hot is a major power leak in the system -- the on times need to approach zero along with the transition times. Mosfets and a good driver will probably result in much more efficient use of the battery.
Here is how the mosfets would be arranged, if you wanted to try my two stage cap charge/discharge circuit instead of just hooking the coil up to the battery through the transistors.

Thanks for the advice. I don't have a lot of experience with MOSFETs,
but will search around and try to gain some circuit diagram understanding.
My formal education in electronics in college only touched on
basic transistor theory.
What I am trying to do, and I'll show this in Ep. 20 .. is to create a sort
of FLUX GATE approach ... pulsing the coil .. and watching what occurs.
So being able to control pulse width, duty cycle, amplitude, etc.
would all be good.
I was thinking it might be nice to have a little circuit that takes
the 600ohm impedance signal generator (or computer PCM) output and runs
it through power-transistors so that a person could
PING a coil with lots more current. Coils respond to dI/dt ...
so you want lots of current ...
I see one guy on youtube uses styrofoam in his coil to watch
for shape changes. Excellent.
Last night I was thinking rice crispies after seeing some videos
on static electricity.
Anyone have a nice circuit that can be driven from output of
signal generator -- w/o damaging the signal generator?
It probably would be safe to use optoisolation .. so that
high-voltages can be present on business end.
"The problem with regenerative amplifiers working at these very
high gains is that they easily become unstable and start to oscillate."
It seems the problems that occur with the old-time
regenerative radio designs ... may be a boon for
designs that want to capture received radiant spikes
and trigger oscillations.
I'm looking at Colpitts Oscillator circuits, Armstrong, etc.
Colpitts is interesting in that you can use one inductor
and two caps for the resonant frequency.
It is a CURRENT AMPLIFIER.
For Armstrong you would need some sort of tickler coil near
the Bashar STA ... not as a secondary like in a Tesla coil ...
but rather as a feedback pickup coil.
Armstrong's oscillator, in the radio days, was known to go
chaotic very easily ... which is a good thing if you want
crazy -- wild oscillations.
We have Solar energy -- solved. We have wind energy -- solved.
Why not "solar wind" energy?
Imagine the so called sea of energy ... zero point.
Everything that is zooming around outside and in your room
and throughout open space (ignoring faraday cages for the moment),
is constantly wiggling. Yes it wants to reach equilibrium and go
back to the "zero point" ... but it is being buffetted and changed
by incoming events from the Sun, etc.
We also have the Earth's field NMR phenomenon. In my location,
which has a field strength of about 40 to 50 nanoTeslas,
the electrons will SPIN at a frequency of about 2080Hz when
subject to the earth's field.
Match that .. and your device is a fluxgate magnetometer of sorts
and is able to observe subtle differences in the field strength.
If that field is BUMBED and JARRED ... your device is no longer
in balance with the Earth's field ... and hence goes CHAOTIC
for a time in its oscillations.
It stands to reason that using ferromagnetic cores will result
in losses that are too great for such a subtle energy.
Air coils, on the other hand, especially large ones of low resistance,
can probably do this fluxgate trick much better.
My research into Hendershot and his so called "fueless generator" led
me to start to conclude that Hendershot was some how
taping the Earth's field ... since the Earth is a sort of generator ..
and we now also know that it is a highly "charged" body trying
to release its energy back into space (as shown by Nasa research
on lightning, etc.).
So it seems reasonable to assume that with a large air coil,
a steady pulsed flux in that coil, and a simple oscillator circuit,
some effects might be measurable.
Wouldn't it be fascinating to learn that many researching in this
so called "free energy" area are simply making devices that
PULL energy that is being received ... using SPINNING magnetic
fields -- which is the common theme here.
One advantage to a "air-coil" approach, over spinning motors,
is that you have near-zero inertia. Energy is lost due to heat and
friction ... so lets not SPIN anything physical. Lets spin only
the field ...
Imagine a TOP or GYROSCOPE that you get spinning on a flat
table. A subtle little wind will BLOW it across the table
or perturb its motion. The wind is a vector force pushing in a certain
direction. If you set up a wind that gave positive feedback
to the gyro ... it would spin longer ... or faster .. etc.
The centrifugal (is that the right term?) force is an F=ma
like equation. Reduce m to near zero and increase a towards
speed-of-light and you start entering that relativistic dream world,
where logic is defied. Where space-time is in a different
relation to the one we live in. Yes it takes a bit of energy
to keep the SPIN ... but like a vaccuum cleaner,
it can pull in nearby subtle energy floating by and involve
it in the vortex ... only to be zeroed out again on the other side.
Any given particle travles with its momentum as before, its just
being BENT along a different path as it enters the spinning field.
Current is the VOLUME of stuff going by relative to time.
By involving more particles in your current .. you increase your
current. An upward and downward oscillating vortex is probably
the most optimum geometry to do this ... and so ask yourself,
what sort of coil structure could create such a back and forth,
in and out, vortex oscillation?
