Selfrunning cold electricity circuit from Dr.Stiffler

@All
My results from the current experiment:

Circuit description: SEC exciter-  1 AV plug with NE bulb-16.25 VDC input

SEC fired and tuned for max (subjective) NE Floating back plate            + leg current=55.6ma   - leg current=55.6ma
SEC fired and tuned for max (subjective) NE Hand over ckt                    + leg current=56.42ma  - leg current=55.9ma
SEC fired and tuned for max (subjective) NE Earth  Plate                       + leg current=60.28ma  - leg current=60.1ma
SEC fired and tuned for max (subjective) NE Earth Plate removed           + leg current=55.91ma  - leg current=55.6ma

Not only does it appear to provide a current path but once established a current imbalance also appeared to remain there. I'm seeing what appears to be more current in the positive leg than the negative leg after I read them balanced and then messed with the circuit by attaching earth ground to the plate. Removing the ground did not seem to restore it. Turning off all equipment and restarting did.

Best regards,

Fantastic. I will post a couple pictures here shortly on a test I have performed.

Great work and correct observation

I?d suggest to use cooling spray to verify these facts.
A nonlinear circuit might have lots of possible operating points -
by sligthly cooling parts of the circuit which might influence these
operating points (transistor and everything which heats up) - its
possible to "rebias" this circuit or to detect other operating points.
If you change the impedance of such circuit - you have the chance
that it "locks in" some where unusal - as if it locks in if you power
it up normally.

As long as you have an "asymmetric" circuit - (and there is no true
symmetric circuit) - the current in the supply wires will be different.


BTW: This can be very useful to estimate the relative output
power/frequency/bandwith of such circuit.

For those with the proto-boards with the Al backing plate and the JameCo 22uH choke with the coil in the base like Plengo, need to do one more easy and fast test. It seem no one yet understands what is going on here and sometimes a picture and a burned finger are worth more than explanations.

So the test is simple, disconnect the 22uH from the exciter collector (on the AV Plug side) and drop the end into a free connection pad. Power the exciter with 20vdc and tune for about 40+ to 50mA. Monitor the tenp of the choke, you do not need a thermometer, use your finger (be careful), don't start it and walk off, you will burn the choke.

Try it and lets all know.......

Here is the circuit.

*Trying again to update this.....

I was told some boards do not work the way I expect, so I wired one up and found a short wire jumper will allow it to work, I have included a picture.

Dr. Stiffler,
I will fire this one up when I get home from work and then post the results.

Best regards,

I tried as suggested with the choke. My work room is cold, I felt heat in about 10 seconds. I also noted that when my finger was on the choke the circuit current increased from the initial 45ma to 70ma.

@retrod
Great. maybe? How hot did it get? How long was the small jumper wire?
If it did not get HOT! be sure it is in a direction away from the power rail lines. In my example if I move the choke to the second connection tier away from the rails it will start smoking within 20 seconds.

Now the big question  if the choke and a pad or two consume this much energy how can any be left for all the LEDs one can drive, or LEDs, neon and motor?


This is a result of the 3.75pF global circuit coupling to the Al backing plate
