@flathunter,

The circuit is up and running now. I'm currently lighting up three
ultra bright warm white LEDs. The input usage (with a 10K base resistor)
is 19,1 Volt @ 0,05 Ampere. The RF output of this circuit is all over
the lower HF band. Main frequency is at 1,68MHz. See image.

Groundloop.

@ groundloop

What kind of distance are you getting?

@stprue,

I do not have any top capacitor on the coil yet. I also do not have any second
coil with top capacitor. So I can't test for wireless effects right now.
The output to the LEDs is from two 1N4148 diodes connected directly
to the top of the coil.

I can walk downstairs in my house and still get an LED to light on an AV plug.  Any conductor in the house will provide the input.  The field is huge, and the house electrified.

@flathunter,

I have to keep the power down because of where I live. I can't
risk blowing up my neighbors flat screen TVs etc. :-)
I know the effect you are talking about and I have seen your videos.
The oscillator you made is a very nice and a smart circuit.
The resonant frequency is set by the coil going to
the base of the transistor and the circuit seems to run very well
without further tuning. It also have few parts and is easy to build.

Hi GLoop!

Im glad there are people here on OU like yourself who r interested in these oscillators - they are great fun, and seem to be able to provide a remarkable amount of light on very little power - sure, no doubt the thing needs tinkering with, but thats where we come in right?  ;)

Thanks for the simple explanation - im no expert with physics, but id like to try to understand some of the theory behind the oscillator.  The transistor acts as a switch right?  I was surprised i didnt have to tune mine when i set it up....is this because of what you're saying with the coil going to the base???  Can you go a little further with his idea??  teach me??  I wanna know more!

Ive noticed these filaments act differently by my oscillator - most of the new ones i bought turn into instant plasma balls (with minimal white light also).  Ive got 3 which dont act so poor.  1 spot lamp which is really bright but has a life expectancy of about 2 mins  (last 2 in video - identical).  1 40 W filament (osram, small) (first on video) which seems to work the best as it last longer - 2 parts burn with bright white light, and 2 remain calm but have a plasma colour.

The last one which is different is a 75W.....last one on my old video rom previous post.

@flathunter,

This is the first time I have seen and built this type of oscillator. And I can't say
that I'm an expert on radio frequency and Tesla "effect" oscillators. But I did build
another small setup to test my theory about the base drive coil. So I did wind a
small iron powder toroid with a collector coil of two turns and a base coil of 60
turns (circuit drawing and image of oscillator attached). The oscillator did run.
It could not be driven by a high input voltage but did run well on 2,5 Volt. When
the oscillator had started then I could turn down the input voltage to 0,6 volt
and the ampere draw was only 0,01 ampere. It stopped to oscillate when the
voltage was turned up to approximately 6 volt due to over powering the transistor
with DC bias via the bias resistor. The "Tesla" effect you are seeing is probably
because you are running the base coil open ended and every time the transistor
switch off (no current going via the base emitter) then the coil become open ended
in both ends and the voltage is free to swing to maximum high voltage level. The
frequency of the oscillator is set by the base coil (as I see it) because the transistor
base will be switched on and off by this coil. Every coil has a capacitor part (because
the windings is close together) and a coil part. This makes the coil a tank circuit (L/C).
The frequency is f = 1/2*PI*SQRT(L*C) where L is in Henry's and C is in Farads.
I have also attached a circuit drawing of a small oscillator if people want to do
experiments with small power.

Fantastic work GL and I would say they are much more then fun but fun none-the-less   ;D

This particular circuit needs much more research but only a few people are looking into it.....very unfortunate!

Anyways I'm glad you're interests have been peaked.

If you want I can re-post my basic circuit of the SEC for the 10th time so more people can test easily!  (I have done this in the  past with no enthusiasm)......

let me know   ;D

At all
tanks to revive  this thread here :)

Thanks Groundloop for your circuit and to have interest in this oscillator. i will give it a try anyway and as soon as possible.

But GL please take the time to wind a big coil (as per Gbluer (Slayer 007)  info ) because i am sure that you will be of atmost help to all of us .

Here my basic circuit (pix 1 ) and now Flathunder  and i  (and other on a other forum ) are working also with mosfet with  interesting result but i think we don't really (or at all) understand what is going on there. ???

And i am sure that very great improvement wil take place very soon. And probably with you,

Always ready to test every thing in my possibility

and good luck at all

Laurent

@stprue,

Yes please post your circuit drawing here. Always good to have several circuit options
available. I agree that we need to research this circuit more. It is a simple circuit to build
with a part count of 3, transistor, bias resistor and coils. My next goal is to wind a 110mm
coil to see some "Tesla" sparks going. I need to find a good hexfet like the IRF830 or IRF840
to drive that coil. I think I have the IRFPG50 hexfet and I think I will try that. But as I said,
I need to keep the output as low as possible due to close neighbors. If you ramp this
circuit up to several Watts then the near field will be very powerful and I can only speculate
what the field will do with nearby electronics. When Tesla was around there was no flat screen TVs. :-)

@woopy,

Thank you for the circuit drawing. Our posts crossed each other in cyberspace. I have planned
to build a big coil as described by @flathunter.

Hi Groundloop

My actual favorite fet is the BUZ 11 as it can support very high current and works very well with my coil setup.

and here the video and some description of the coils dimensions  (for a good plasma jet ) if it can help

good night at all

Hi Woopy and GLoop - Thanks for explanations and diagrams!!!!  They are great - please leave your sec here too, sptrue

I made this video to show the difference between different bulbs.  Look carefully at how the first bulb and last 2 bulbs compare with the middle bulbs.  They produce far more white light. 

http://www.youtube.com/watch?v=aF75AO0qfSc

You are completely right Woopy - those spots dont last more than a few mins.  The white light seems to crack the glass (that sound you hear - same as me!), but they are the brightest - maybe they need a little tampering with??  any ideas...???  The first bulb i think is also worthy of attention as its very different to the rest of the plasma globes....it has plasma, but not much....mostly power.....

Good luck guys!!!

This is the Exciter Circuit I will have been using...sorry for the repost!

Directions on how to replicate:

4KV Trigger coil
Top leg=output connect to pan
Bottom front/right=collector
Bottom back/right=not used
Bottom back/left= + rail

Transistor
Emmiter= - rail
Base=Pan
