Joulethief SEC exciter and variants

[slayer007]

Hi .I discovered a strange modification which significantly reduces the current draw on both my Simple sec exciter and also Slayers exciter and may be worth trying on a joulethief.This is what i did.I added an extra transistor and connected the collector of the new transistor to the base of the original and the base of the new transistor to the originals emmiter and left the new transistors emitter floating.The current draw drops by over half and output is not realy effected.Whats more is you can keep adding transistors like so and the current draw comes down with each addition.If anyone has any thoughts on why this floating transistor is having this effect i would be really interested.
I have also had a think about the wireless transmision aspect of these circuits and come up with an updated simple sec reciever circuit but it works equally well with slayers exciter.
I am getting an led to light at over 2 meters distance.
I also did an experiment with slayers exciter and got it lighting an led on a vinegar battery so i think the lemon is a go'er .
Here is a vid of todays experiments and circuit diagrams of power saving mods and wireless reciever circuit update.Jonny

Jonny Great video.
Your receiver circuit looks like it's working very good.
Thats a good range to be working wireless.

I think the extra transistor is acting like a diode from the emitter to the base.
I tried it and it's just like you said the current draw was cut more than in half.
But my light output was also cut in half.I guess you get what you pay for.
But I could get it to light the 40 leds to 1/2 brightness using the cell charger and the led on the charger didn't even come on.
You can also get the same effect by using a diode from the emitter to the base.

@Slayer.Hi The first thing i did when i saw this effect was to swap a diode in and it doesn't drop my amp draw like the transistor does and i tried a few different diodes.My power output does not seem to have decreased much and in fact it may be working better for wireless but i will have to do some more tests.Did you try it on your circuit or the simple sec?Many thanks jonny.
@Xenomorph.Good to here from you and i hope you are well and your experiments are going good .Jonny.

Hello Jonny.
I tried it on my exiter circuit.
I had the 20w FL lit then I connected the extra transistor.
The current did drop from 50mA to 10 to 15mA the FL did stay glowing just a little.
Then I tried it with a 1n4148 diode fron the emitter to the base.
The current droped like with the transistor but I do think it did drop a little more using the transistor.A few more mA anyway.

Slayer's big coil

1 # I made a 3" x 14" coil, with a 9 turns L2
I don't have the big field as Slayer's one, and can just light dimely 2 x 10 W tubes.
I wonder where the problem comes from ?
- is it because I am not using a 2222 nor a MPSA06 ?
- is it because I don't use a breed board and don't have the capacitance effect ?
I just bought some 2222 today and will try again, with them, when I'll be back home.
I thought I would be the first to show an "Ever Lamp" (a lamp self-running, without battery nor capacitor), lighting a 20W tube and collecting it's light with my 5 W solar panel to supply the small 250mW necessary to run the circuit (5V x 50mA) but it seems that destiny was written differently... I can't get it to work properly for now ...

2 # The comparaison between Tesla coil (magnifying transmitter) and cohesion circuits (SEC) had been made in previous posts;
see post 405 and 422 : http://www.energeticforum.com/renewa...in-air-14.html
(I don't bring this subject for polemic but for objective investigation)

Transistor array for overunity

The cascading transistors reminds me Tom Bearden's story about the minuteman missile and the discovery of COP>1 with multiple transistors.

Quote: A frequency converter using 64 transistor stages and similar sophisticated feedforward and feedback mechanisms was placed in the original Minuteman missile, then deliberately modified to stop its demonstrated COP > 1.0 performance. Very quietly, Westinghouse engineers then obtained several patents surrounding the technology, but no further mention of it appears in the literature. End quote

I found the docs :

you might be on their trace !!
keep on the great work guys !

@JonnyDavro:

Do you remember your one magnet Bedini motor when you placed the little 12V Relais in front of the transistor base and that would reduce the current consumption?
Maybe the "Gods of current reduction" would be asked too much hehe, but it might further reduce the amp draw (if the oscillator is not disadvantageously detuned by doing so)
Maybe you can test that?
Good luck

@ Steph,

You do not want to be polemic, but i do not care.
SEC exciter is Tesla's resonator known as "magnifier" or a common oscillator setup coupled with an extra coil not inductively connected. It is not only the resemblence striking, its the underlying principles are the same also.

The main difference is that SEC is a small, toy size, solid state magnifier, that actually does not magnifies voltage that much (althouth has enormous Q, it fails to achive great voltage rise due to EM radiation etc)
. I do not have any o-scope or any measure decice, but judjing by the fact that it cannot burn the fast diodes 1n908 its volatge must be below 100volt.

By the way, this design allows ultra efficient oscillators, since a huge energy part is spent to heat (in common Tesla coils solid state or not) due to loose coupling between primary and secondary.

If you read Colorado springs notes, Tesla suggests ultimately a tight inductuctive coupling should be good for energy efficiency between oscillator (forced oscillation) and extra coil. But this in turn creates other problems due to mutual induction between closely coupled coils in the primary oscillator.

The SEC or else solid state magnifier is a clever arrangement that does not have the drawback of mutual induction (since a single coil for producing the pinging), only the parasitic capacitance of the transistor can pose a problem to the system.

Actually at some point i am planning at making a Solid state magnifier, ala SEC style, only bigger more to a normal tesla coil.

A note: Playing with my SEC 15-3, after reading Colorado Spring Notes and understood how those are supposed to work, SEC's performance and stability greatly increased if in the possitive pole of the battery you make a ground connection (etc a water pipe)

Slayer's coil attempt

Hi Slayer,
I got improvement after using 2 x 2n2222 in // and making a nice flat L2 and using a USD charger 5V from 2 AA.
But still I can't get a tube to full brightness, even a 10W.
May be it is because I don't have MPSA06, or may be I must change the wire size ...

- Did you try with only 2222 and no MPSA06 ?
- Did you try without the breeding board ?

And to get a good view of the light output, could you make a comparative picture with a 20W lit from the wall outlet ? because I still confused by my results.
Thanks and good luck,
David

Stephenafreter what size wire are you using?

The L1 coil I made I used 23ga. magnet wire and for the L2 coil I used 21ga. plastic coated wire.

Voltage also makes a differance in tunning.Try using a higher voltage and also try adjusting your L2 up or down to find the sweat spot.

Tunning coil

@Slayer
HI, thank you for your reply. I am using #24 for L1 and #23 for L2, but both magnet wire.
But I don't have the 2 collecting circuit, BEMF and reverse diodes on supply.
Does it work with the same light output WITHOUT the 2 collecting circuit, or are they a must, to get it to work ?

Yes I tunned it to maximum brightness by moving the L2 up and down
I am not looking for very low input now, but I want to get full brightness on a 10W tube, to make it a replacement of existing devices that run on 12V batteries ...
Thanks,
David

Edit: I just realized that I was not using the right wire size, I will change it to #23 and #21.
I just checked size here : American wire gauge - Wikipedia, the free encyclopedia

slayer007 circuit replication

@ slayer007

I tried your basic circuit and it works great. The LED on the phone charger looks bright so this is probably sucking power, but the tube is bright.

@Stephenafreter No the caps are not needed for the light.
They are just part of the collecting circuit.

@ Xee2 Nice work thanks for posting your results.

question for slayer007

@ slayer007

In your video with the big coil, the fluorescent tube seemed to light without any connections at all (as long as it was near coil). Is this true? With my replication circuit (using cell phone charger) a fluorescent tube will light with only one wire from the coil but it will not light without a wire.

I replaced my 2T:60T coil with a 2T:30T coil and the output voltage droped from about 600 volts to about 150 volts. Since the inductance was reduced by 4 it seems that maybe the output voltage is a function of the coil inductance. So, more idcuctance may mean more output voltage (and lower frequency also I suspect).

Yes the FL's will start to light about an inch away from the coil.
They will stay lit up to one foot away after lighting if your holding it.
I tried some bigger coils but I couldn't quite get the performance with them that I was getting out of the smaller coil.
There is a lot of different coil setups you could try it's just finding the right combination with L1 and L2.

wireless tube using slayer circuit replication

I was able to light a fluorescent tube wirelessly using slayer007 circuit. But tube ends need to be less than an inch from the metal plates with my setup. Tube ends can be about 2 inches from metal plates if 9 volt battery is used.
