I'm not sure about it as well so I don't want to spend a fortune trying it out if its not going to work LOL so I have not changed anything yet, This was just an idea if the captret thing would work.

The transistor ambient square wave driver circuit works fine. I don't need to change it, But if I can find a better way to drive it, Id like to explore that as well.

Negative Resistance Amplification. Just pondering today as it is related to my circuit as I use this for a driver with the transistors (way back to the first post in this topic)
And was just pondering over its effects in general. Thinking of ways I could better utilize this whole stage. Or maybe even build something better. Or modify what I got now. Who knows. Just one of those pondering days.  :-\

Negative resistance devices are really interesting! Because when a negative resistance device gets voltage applied to it, an increase of voltage (within the negative resistance voltage threshold range) Decreases the current usage. Because of this reaction. Negative resistance devices such as tunnel diodes. Where used in early oscillator circuits and amplifier circuits, But their usage, As a low current device. Made their popularity fast diminishing. As the demand for more RF power increased. The transistor's better current handling. Simply bridged that gap and was better to work with on low frequencies outside the microwave band as the tunnel diode was mostly a "Two terminals" system. As transistors have 3. 

So the first thing one wants to think of when they learn about negative resistance. In a matter of getting free energy. Is simply to calculate your regular circuit or device's resistance in ohms. And to just "counter" it. With the same resistance of negative equal value. Consider our circuit uses10 ohms. One would think of just adding 11 ohms of resistance in the negative 11 value ( plus 10 ohms next to -10 ohms would show up as an infinite perfect shorted out conductor of pure 0 ohms resistance) of negative resistance and tada free energy. Our fantasy circuit (negative resistor injects current back) now supplies the extra current to counter the positive resistive load!

But no, Close but no cigar. We don't actually have negative resistance devices that are in the -ohms. One can not just order from a factory a negative resistor of -11ohms. If it was only that easy huh! But what we have in electronics. Is a noticeable effect called negative resistance, This acts upon a change of voltage. By bringing the DC voltage up in a tunnel diode, At some point once you reach this positive voltage threshold. The internal resistance of the already positive resistive device, drops slightly. So for example. To simplify, If the resistance at 1 volt is 100 ohms, And you raise the voltage to 2.5 volts. By doing this. You enter the negative resistance threshold voltage range of the tunnel diode, This acts upon the device and causes the ohms to drop to 15. Please notice it is not a value of -15!! So now at 2.5 volts, The device shows a positive resistance of only 15 ohms. Notice how the resistance is still positive and will always be. We call it negative resistance. Because if you plot it on a curve tracer. You can notice the effect from the drop of resistance with a voltage increase within a certain  zone. If you push it some more. And go over this voltage threshold, Current usage goes back up and the resistance goes back to 100 ohms. Back to the same positive resistance value in ohms, where we first started at 1 volt.

Some thoughts....

So its clear we can't run a pure "Negative Resistor" to generate free energy. Ah darn!!
But what we can do is experiment with tunnel diode's low current/voltage AC amplification properties. And run it as an ambient AC current amplifier.

Can this effect be used as a very low voltage and current input "DC bias" AC amplifier and have more on the output side with such an apparatus device, as a whole consisting of multiple combined systems to make operational?

For example. If one was to build one of Tesla's Colorado Springs alike high frequency oscillator, His magnifier transmitter, And have nearby the pickup coil/loop/antenna on a separate receiver device/circuit, for example with tunnel diodes, Using just a small isolated DC input low voltage/current drive. Like a battery of 1.5 Volts DC, Or a solar cell in the sun etc for the source of small DC power at the receiver/amplifier circuit... And with the help of this negative resistance, AC amplifier circuit configuration on the receiver device. Could perhaps couple the AC (radiant) energies generated by the magnifier transmitter nearby and other nearby radiant energies. It could "Suck" in ambient or as Tesla calls it "Ether" and rectify this amplified AC output stage to DC and get more current on the output as a "Whole" using multiple systems together as one apparatus?

But your probably thinking, If everything is to be looked at as one device. Then we must look at the generator's power input  requirements as well. The magnifying transmitter stage.  And at the ample amounts of power Tesla has driven into it, This would probably take a while before we could match an output of more on the receiver side. If ever even possible! But with that said......

Food for thought, How would you go about in proceeding with these types of experiments?

Tesla used huge voltages and currents for his experiments, Today we don't need big "Tesla" coils to bring our voltage up to spectacular voltages and high frequency. Our capacitors are smaller and more efficient today, our L/C circuit components are much more stable today. And we now have transistors and tunnel diodes, So with that said, With just a tiny 2n2222A transistor fly back type of circuit. Low voltage and low current, Can produce plenty of high frequency and high voltage spark!(think of fly zappers!) Even with just one battery of 1.5 volts DC, That little oscillator will produce an electrostatic like intensity zap if you touch! I done this myself many times. Perhaps such a simple circuit or device could be used in part to replace Tesla's huge voltage requirements and huge transformer structures to get high frequency AC. For his magnifying transmitter to function. I think we can replace most of this "Transmitter" or driver circuit  with tiny solid state parts! If we can figure this out, Then perhaps, Just perhaps, We could find that the wireless receiver station nearby, generates more output then input when adding the math, combined together with the drive requirements of the transmitter.

Tunnel diodes are current limited devices so, One would think that you will never get huge amounts of amplification from a tunnel diode amplifier setup, But perhaps if we don't need much of input power at the "Transmitter"  We can get more on the output as little as that more may be, If we can charge a 12 volt battery or run a led lamp for "free" and show a proof of concept. Why not. Again probably because tunnel diodes are low current. Many experimenters look beyond. I think an important key for any chance that this concept may work is that I just have a feeling that as long as we have high voltage high current oscillations, We can saturate the nearby area with radiant high frequency energy and that perhaps is the key to making this work?

Raycathode:
Err can you still get Tunnel diodes ? most of them in the 80 were Russion I used them as a time bas trigger whats more is they would blow dead easy.
any way you can fabricate a very close device with a p and n channel junction pair of fets jut never tried it with the now available power version
if you can only get the one polarity you can use a transister for the polarity you cant get.

So anyway how you going to get free enery with it ? the old TV sets use to use a fly back diode or boost diode do you know haw that works
and how it works or the idea behind it in a TV set lopt circuit ? most people dont know, do you ?

Just open for thought. I already experimented with the tunnel diodes as ambient amplifier circuits and it works fair. I can get over 12 volts DC with it. But the current is only around 50ma, It jumps around depending on local conditions of experiments. That is why for  now I only use it as a trigger for switching and discharging a capacitor producing a pulse wave. But that is where I am at for  now. On it's own I can't do much more with it. So I worked it in with my project as a "stage" or section.

So I was thinking about Tesla'a Colorado springs experiments,  These coils where not the typical Tesla coil we all talk about.  What he was working on and nobody knows 100% what the final goal was, But many speculate it was in part for the Wardenclyffe Tower.?

Looking at these coil assemblies, They look more like primitive HF radio spark transmitter circuits. Tesla's work shows various networks of these L/C circuits. Some extra coils where capacitor shunted, Others where  not. He played with various configurations until he got the optimal what he called magnifying effect. Looking at some of these circuits more closely it looks like his high frequency generator was also coupled into a high frequency receiver and he tuned all for max smoke with tuning and resonance. His Transmitter was also in part the receiver and the sparks you see in the photos from from the receiver coil(s) acting upon the tuned vibrations of its L/C tank stage. He also had to "isolate" some stages with capacitor shunts on some of the extra coils in the circuits. Looking at his Colorado notes you can see all these configurations in more fine detail.

He had a system in mind, Not as big as providing the world with unlimited amounts of Free energy with his Wardenclyffe Tower. But also explored the possibility of short range low power transmitting. With similar effects. And he did have some results with this. And this is where I am heading towards...

Tunnel diodes can be used as an AC amplifier and they don't require very much DC drive. Downside. They are a low current device. I know!!

Maybe even "background" noise could drive this negative resistance amplifier. with DC bias.

Tesla's coils also generates all kinds of high frequency harmonics, Very strong ones, He could go ahead tune and utilize. He describes it as well.

So creating a fundamental note or vibration but tuning into one of its upper harmonics generated out of the coil, As long as the vibration source keeps operating at the fundamental frequency, If an object, (in the case of electric circuit then an L/C circuit,) nearby at a higher frequency starts to vibrate in resonance, The vibrations just keep getting more and more and more powerful or intense on the "secondary" device. I Think Tesla wanted to utilize this effect somehow.

I know it works similar with RF as I have built some tiny very crude signal generators over the years and the basic ones with no filtering cause not only harmonics but what appears to bring in close proximity to the coils all kinds of super strong radio waves from other sources nearby mixing in and creating all kinds of frequencies and what seems like a whole mess across the spectrum with not only my harmonics but for some reason "sucking" in all the junk nearby and injecting that into the awful mix. Even creating some new ones! But it must be magnetic or something as this effect is only in close proximity to the transformer coils.

So what I'm getting at is maybe all we need is a sort of "bait" signal and we can then help ourselves to these strong local generated "radiant" noises and perhaps we could get more output from the receiver side, taking everything else, like other signals and ambient noises with it into consideration.
