Selfrunning cold electricity circuit from Dr.Stiffler

[Spokane1]

Dear Non-Funded Researchers,

One more important modification that will be of great assistance in this exploration:

Replace the fixed inductance on the "primary" side of the antenna loop stick with a variable inductor as shown in the photo below. With this modification I was able to find an oscillation mode that provided enough voltage gain to light all 92 LED's in the load array, however it came with the cost of additional curent from the supply battery (81 mA). Adjusting the inductance has a profound effect on the measurable DC current at different capacitor settings. The example inductor was modified by removing one layer of copper wire. It now has a range of 1.6uH to 16.5 uH. The original 1" - 10 Turn hand wound fixed coil had a value of 2.6 uH. It is shown in the photo (disconnected) to display its relative size difference.

It is my technical belief (at the moment) that the function of the added primary inductance is to reduce the effective coupling between the coils on the loop stick.  When k=0.755 then 3rd Harmonic voltage addition is possible. See "Induction Coil Theory and Applications" Taylor Jones 1932.

The variable inductor allows several more modes of operation to be evaluated. I have attached some .GIF images from my scope to show two examples of the many. The attached scope traces are the taken from the voltage across the collector ? emitter of the switching transistor. D005 is the mode that is running all 92 LED's at a moderate brightness, while D005 is a different mode in which the LED's operate at a much lower brilliance but at only 30 mA. (I don't know if this site can handle .GIF images so they might not be displayed)

The adjustments between the variable capacitor and the variable inductance are interactive. It will take patience to explore all the resonance possibilities that this circuit can provide, even a circuit as simple as this one. I would suspect that only certain operational modes are candidates for any hoped for OU properties.

Submitted again for your consideration.

@ Ben K4ZEP

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

While I wasn't planning to sell the boards, you can easily have one manufactured for yourself, at reasonable cost via the internet. Just follow the  steps (below). Often, this can be a next day delivery.  While I was originally planning to make my own board, the thought of drilling 160+ LED mounting holes, is making me think twice, so I will consider splitting the cost on a board order with you, as there is often a minimum quantity of 3 or 4 boards involved. So if you do decide to order my unmodified circuit, let me know. (Also if you have new extra ferrite coils...)
As for your other question, I think you mean the 330K resistor. My circuit board is based on the 'Thomas' schematic at http://www.drstiffler.com/ce4.asp  This correctly connects the base of the transistor (middle terminal) to 12 volts. Feel free to edit the PCB art for your own use ( see Step 5 below). If the change turns out to be an improvement, let the forum know, and I will consider making it a permanent revison.

Regards,
DerrickA


HOW TO GET THE CIRCUIT BOARD MADE FOR YOU
1) Download the ThomasPCB.zip file from my earlier circuit board post.
2) Extract the ThomasOscillator.pcb file from the unZipped ZIP file.
3) Download ExpressPCB  (the program I used to make the circuit with) from http://www.expresspcb.com/  (This is a FREE program)
4) Open the ThomasOscillator.pcb in ExpressPCB
5) (Optional) If you wish, Do any editing to the circuit you want, for your own personal use.

    (The rest of these instructions are excerpted from expresspcb.com)            
6) Before submitting an order, you can get an exact quote to have the boards made using the Compute board cost command from the Layout menu.   
           
7) To place the order, select Order Boards Via The Internet from the Layout menu (you must first have your .PCB file loaded).   
           
8 ) In the order form, fill in your name, address and email address. Select the manufacturing option you want (i.e. Standard, Production, 4 Layer-Production, etc) and enter the quantity of boards you need.   
           
9) To pay for the boards, enter your credit card information into the order form.

Note: The only method of payment we accept is credit card. We accept: Visa, Mastercard and American Express. The credit card information must be entered into the ExpressPCB program at the same time the order is placed.   
           
10) Before your order is sent, you will have a chance to review the exact cost. To submit the order, press the Send button. You will receive email confirming the order within one hour.

Hi All, I am making huge progress.
I saw, that it is best to place the 2.2 uH coil directly in front of the AP !
Then I just put instead of the 2.2 uH coil another litz coil onto the core in front of the AP plug. Now I have this way 3 coils on the core and am using a BC 555 Thomas circuit oscillator and the LEDs are really bright now at 15 to 30 mA and 12 Volt input.

Ben K4ZEP is Ben Thomas, developer of the Thomas Oscillator. The circuit on my web site is a modified version (modified by me) with Ben's permission. Please be aware of this should he comment about changes, I think he is making reference to his original design of which he has commented to 'Spokane1' in suggesting the tunable base cap, etc., just FYI for you all.

@Spokane1 and @All

If you can not hold one end of a neon and touch the other to the input of the AV Plug, SEC conditions is not possible. If this HV is not present and interface is not established.
Both sides of the neon will light at the Plug input. Then when touched to the output of each diode, alternate neon electrodes will light to match polarity.

Thanks....

With a magnet near the core and the coils I can now control the core ringing and adjust for optimal brightness of the LEDs and minimal input.
I get the optimal brightness at mimimum input current, when I have some ringing ontop the positive wave. With the magnet I can control this ringing and adjust for minimal input power, while the LEDs stay at the same brightness.
At my collector versus emitter at my BC 555 NPN transistor I get a p-p voltage then from around 1 to 40 Volts !
With the magnet I can control this amplitude peak and the higher it goes the better it is and the less input power it draws at the same brightness...!
