..... .....  The spikes are being generated by the spark gap and it is here that gain in the circuit starts. .....

The trouble is that it makes too much noise.
It is a terrible sound.
Anyone who demonstrates it on youtube cannot talk over it while it is on.

The work is not finished, but this is my reason for wanting to use the JT or such solid state pulse maker to produce the same thing... but quietly.
It must be possible.
I am SURE that Tesla would have made a quiet version as soon as the transistor was introduced.

@MK1. I watched those videos and they are helpful. Thank you.
@Sparks have you not been able to produce the same effect but with a solid state device?

thank you,

in closeing for tonight guys ...  i took out the 1f super cap out

i can charge it and burn 2 leds normal and watch my super cap climb in charge ... 


just thought i would share it with ya!

ill make a video tommorow

nite!

ist!

     As the radio world started to push the envelope with producing shorter wavelengths it became increasingly difficult to create a valve that would hold up.  Resonance would setup inside the tubes themselves.  The standing waves or reflecting energy would create nodes and antinodes inside the tube with the accompanying polarized electrostatic potential between different parts of the tube.  The resulting discharge of this unwanted voltage would melt the tube down.  This is why the cyclotron or microwave oven was developed.  That is why we dont put metal objects inside microwave ovens.  The standing waves create nodes and antinodes on the metals and the electrostatic potentials rise high enough in the metal to ionize air.  The ionized air is then a perfect conductor between different parts of the metal and the sparks start flying.  Radio people want to produce one standing wave at the transmitted frequency so that the node of the wave ends up on the top of their antennae.  So for each oscillation only one wave is produced which travels on out of the antennae and dissipates into space.  Whereas Tesla wanted his waves to be reflected so he wouldnt waste energy pumping the antennae circuit.  He built a system where the oscillator is the antennae.  The standing wave ratio is pumped up to infinity.  Each oscillation staying inside the antennae.  He built his famous bifilar wound pancake coil which is an rc tank and once excited will selfoscillate for a long long time.  Each input increasing the power in the circuit.  What is called the scalar potential recognizes the energy density of space.  This cold current flows towards the oscillator out of everything then disappears.  I have seen it and have no idea where it goes or where it comes from.  It can be interrupted by metals and coils in the near field of the oscillator I am told and originates in the Earth itself.  It does not travel inside a conductor but along its surface if the conductor is insulated.  Weird science.

New video on the Tube of a Super Joule Thief:

I just found this and 2 guys pm'd me about it on youtube.  One guy said Lidmotor is already going to build one.  this circuit will work with an inductor made of only 1 turn of insulated wire, no core at all.  It uses 2 transistors, one npn and one pnp.

Worth seeing.

i built one of those two weeks ago...
theres a reason i didn't report back here with info...
he is lighting a 1.2 volt led with it... that should tell you something there..
before i could get it to light a 3 volt led i had to change alot of the circuit and then it use way more ma's
