Selfrunning cold electricity circuit from Dr.Stiffler

[plengo]

@Dr. Stiffler,

congratulations Doctor. Amazing stuff. THank you!

I could reproduce the experiment tonight and oh boy, that thing runs and bites. IT is very impressive. I could light up over 80 leds. It has very weird behaviors. Touching the hand reacts a little bit differently from the other experiments that I have shown at youtube. Once I turn the circuit on it takes about 2 to 5 seconds for it to regulate to the point of lighting up the LEDs.

I could not run it above 9v because my transistor would simply burn. I ran it also using a 9v battey and it runs very nicely. I will try tomorow to measure more the input/output to see if overunity is there. This design reminds a lot of Bedini SSG concerning the High Voltage. And it is true, do not touch it unless you want some shock. This kind of electricity is definitely different from the other one I could create using only the FuncGen and lamp coils (as I have been talking previously). This electricity feels more fluid and it is not cold at all. If seams that it permeates everything almost like a gass around the surfice of everything around and any thing changes the whole dynamics. Tonight was my first time really playing with this kind of electricity and before I only have heard of it.

I can barely wait to play with it more tomorow.

@all
please do it. It is so simple my daughter could build it. It is really fun and there is lots os things to learn here.

I also posted some videos at http://www.youtube.com/watch?v=_zXH5WJjXtQ (there are at least 3 videos for tonight).

Well done !

I have just watched your 3 Youtube videos and be cautious to touch
it.

What frequency do you have at your output ?

If it is in the Khz range only, then it surelywill hurt,
when you touch the high Voltage.

When you are theinMhz range, there the skin effect
should prevent an electrical shock, but it might just
be then a heat burn on your skin ?

Do you have a scope and can post scopeshots
at the transistor collector versus ground ?

Many thanks again for your hard work.

I think I must try to use also just a simple transistor
and use input current.
In my last testI get 30 Volts across the 10 LEDs.
But the current is hard to measure.
One meter shows
about 1.4 mA and another shows about 4 mA
and a 1000 Ohm shunts also shows about 1.25 mA
on the scope...
( as my scope head is only 100:1  I must use a bigger shunt,
but with the 1000 Ohm shunt the brightness is not reduced, when
I have this in series with the LEDs... hmm, that is curious...)

@plengo,
please put a big metal plate or alufoil in connection with your LEDs,
then they will light up much brighter..

As promised, I have now created a printed circuit drawing for the Thomas oscillator that you can use for your own NON COMMERCIAL USE.
This has not yet been reviewed, so if you are timid, do not build this unless you are willing to make your own modifications, at least until revision 1.
For those of you experienced with PCB layouts, please take a look, and let me know if you spot any problems, missing traces etc.
All artwork and an explanation document are contained in the file ThomasPCB.zip (attached)

Enjoy,
DerrickA

P.S. The drawing below will probably show up about twice the size of the actual circuit board. (2X)  This board can fit up to 80 LED's  (yellow circles).

Do you plan to sell any of those PC boards......I sure would buy one if you did..I would prefer that the top of the 220K resistor went to the collector instead of + of power supply (if my old eyes are right) but not a problem to modify it that way....Ben K4ZEP

Thanks Stefan.

What frequency do you have at your output ? It is 2.5 mhz. On the picture you will see the pulses and the TDiv is .2useconds (.2 microseconds).

And you right, if I touch it just lightly enough it burns as if it was very hot.

Osciloscope set to both probes at VDIV 5v and TDiv is .2useconds (.2 microseconds).
The first picture is the colector and ground with probe at 1x. Second picture is the negative of the diode at the avramko plug and no ground (second lead is disconnected), probe set at 10x. Third picture is both signals together. All signals are center screen zero, in other words, above half of the screen is + and below is opposite current and it is -.

Last picture is both signals again (collector and ground / avramko plug negative) but with both probes set to 10x so that you can have a better view of the potential difference.

Input voltage now is 9v and 130ma. I have tested with many voltages and currents and I can get all LEDs to light at 4.5v input, current at around 50ma but them I need to connect a big spoll (lamp wire or ground) to any LED to light them.

At 12v and no limiting on the current which can go to 250ma I dont need the spoll anylonger. All LEDs fully bright (hurts the eye) BUT can not run it for too long because transistor gets so hot that it burns.

I was able to run it with 12v and 60ma if a 223pf cap is between the base and ground. LEDs seams to be the same brightness and scope still shows the same waves/voltages/times.

I dont think I got this transistor base setup to the proper voltage/amp because I dont think it is turnning on/off once the whole thing runs. I can disconnect the resistor from the base after it is running and nothing changes. Anyway, the whole circuit presents lots of "stray capacitance" everywhere ( I really think this cold electricity or radiant electricity behaves like a gas anyway) which could affect the base of the transistor.

Dr. Stiffler is right about its auto-resonance. Even if you insert or remove LEDs, resistor and caps, it finds its best frequency automatically. It must be because of the oscilations from primary and secondary turnning on/off the base of the transistor (very similiar to SSG from Bedini).

I have much to play still. More measurements to come. Just wait.

My transistor is PNP 2N3906. I tried with other ones but this was the only one I could make it work so far. I have to tune the hell of this thing. The other components are the same as specified by what EMdevices printed some posts ago. The LEDs that I am using are not all in series. There are 25 in series all the rest are in parallel in different configurations.

Dear Non-funded Researchers,

Per K4ZEP recomendations 11-22-07

The Thomas Driver, as described in post #889 11-22-07, can easily be modified to increase its power output 23% (from 65 LEDs to 80 LEDs) while at the same time reducing its relative current consumption by 22% (70 mA to 54 mA).

1) The switching transistor was replaced with a 2N2905 fitted with a 2 watt heat sink (very obsolete - but has a higher power capacity than the 2N4104 used previously). This is a silicon PNP device that required the polarity of the battery to be reversed. Fortunately, the Thomas Driver is so simple that it can easily accommodate this change with no other circuit modifications.

General Description of the 2N2905 for reference:

Type: General Purpose Amplifier and Switch ? Silicon PNP (circa 1975)

Vce = 40V  (Needs to be higher as observed Vce in this circuit is in excess of 60V)
hfe = 200 at Ic = 150 mA
ft = 200 MHz
Pd = 800 mW  Metal Case

This swap out demonstrates how the characteristics of the switching transistor can positively impact system performance. This transistor is, most likely, still not the optimum model available for use in this kind of application.

2) Replace the fixed Silver-Mica feedback capacitor (56 pF) with a variable air capacitor (13pF to 110pF shown) and adjust for maximum peak-to-peak voltage across the collector-emitter of the switching transistor. In this example circuit a performance hump was found at a setting of 36 pF.

It is highly recommended that researchers who intend to explore circuit development with the Thomas Driver and its future variations consider investing in a selection of variable air capacitors. Having this adjustment feature certainly helps ?tune? the circuit for maximum performance especially when a number of different switching transistors are being evaluated.

3) As a side note. The AV plug sub circuit in this example circuit contains no filter capacitor. Adding one has no visible effect on current consumption or brightness level of the LED?s

Again, No OU is claimed for this example circuit?s operation (at this time). The switching frequency of the blocking oscillator is 1.67 MHz while the resulting ringing frequency is 8.47 MHz. The green test clip shown connected to the LED array is the means by which the number of Load LED's are selected.

Submitted for your consideration
