The bifilar pancake coil at its resonant frequency

[TinselKoala]

Booze hound!

Better watch out, the Drop Bear might come and getcha!

[ramset]

yeesh that bear gives me the creeps....

In the meantime perhaps a discussion of  these on topic experiments ?

I have many years sutying the pancake coils and this is my last video about my "multifilar pancake coil", this consist in six groups of pancake coils, one group consist in six pancake coils connected in series, all the groups are isolated from each other and all the pancake coils are in parallel in the same place (in a PBC PIPE) in my experiment i am using my circuit JL94 with two transistors like the drawing diagram that i am presenting in my video, when i move a magnet in the centre the circuit and the coils "enters in self oscillation" and all the groups "induces" the current to the led bulbs with great intensity, i have connected to the circuit only one group of pancake coils, the other groups are "pickup coils".
this is the experiment...: https://www.youtube.com/watch?v=0Ln7AEpxMeY

Grum's  replication of Nelsons schematic below [more replications to come]
https://youtu.be/m6lmd0HKxOw

the transistor schems below [posted by Tinsel] are for explaining the seeming "selfrunning" when the gate is removed in Grum's vid.

also to note the Neon bulb Vid will hopefully be discussed here too, as well as the power required to actually light this 80V NE2 neon bulb

Note ...there may be a few other ON TOPIC Vids added to this thread as time goes by

Neons like the typical NE-2 or NE-2a require very little current to light up quite well, once the "striking" voltage is reached. Typical currents are 400-800 microamps. And the voltage to sustain the glow drops a bit once the striking voltage is reached. So a "90" volt neon will strike at 90 volts and can stay lit as low as 60 volts, while needing only, say, 500 microamps of current. (But since the resistance of the plasma is very low, they can draw as much current as you will allow them to, with sometimes disastrous results, so current-limiting resistors are typically used in "ordinary" applications. )
So... figure for example 75 V x 500 uA = about 38 milliwatts of power or even less for a good healthy glow. This is not much more power than a typical high-brightness 5mm LED needs. Or, looking at the minimums, 60 V x 400 uA = 24 milliwatts. Whereas a blue LED at 3.3 V_f  x 10 mA = 33 mW.  So you can get a NE-2 to light up with ridiculously low amounts of average power especially if you pulse it with very short pulses.

Or I can, anyway.

Nice demos guys but you should focus to the problem, which is overunity from bifilar pancake coils. This it the only thing which matters here. You should think on it every time, you're posting something here, or you'll lose drive and later even motivation to continue and you'll become a resigned pathoskeptic like TinselKoala. Like it or not, the inventive mind requires focus to problem and a discipline. If you look at the biography of all great inventors, you'll realize, they were often quite average people in many aspects - but they were always sharply focused and dedicated to particular problem, which they solved. The mindless senile twaddling and tinkering fancy demos from JouleThief circuits is very comfortable and maybe entertaining life style - but it will not move us forward: even if you would make thousands of such an "experiments" during whole your productive life, you'll not become an overunity expert anyway.

I can see a connection point in NelsonRocha circuit and Jorge Rebolledo's layered pancake coils: these devices both generate the variable magnetic fields of the opposite polarity against each other like so-called bucking anti-Lenz coils. Such a fields produce a scalar waves in my theory, i.e. the compression waves of vacuum, which temporarily change the speed of EM wave propagation and create anapole condition for overunity. Instead of ferromagnet you can use the evanescent mode of EM wave propagation along wire as an active environment. The layers of pancake coils are better than single coil, but you should ensure, that the current will always flow in alternate direction across neighboring wires, which requires precious construction of coils.

Seems , are improving the interest in NE-2    i left a very nice book to people love "play" with them https://drive.google.com/open?id=0ByZY5hj0h0hXaGZZUGRVYklkM0U and another https://drive.google.com/open?id=0ByZY5hj0h0hXS3Npazk2blBzMWc
