@plengo: did you already try to replace the battery by a charged cap? does it work "forever"?

@Silvije: had a look on your page. what do you mean by: "once started will continue oscillating indefinitely." I asume you did not disconnect the 3.5V power supply. Only the input pulses, didn't you? thanks...

Replacing the battery with a Cap will NOT work. You can put a "dead" battery and it will raise in voltage on this device. The battery has a varying resistance that changes as the voltage increases and the device oscilates. The cap will not do that so it will just discharge to the regular conventional theories of Cap and Resistors.

Thats why I replaced the second battery on the right of the diagram with a short so that the battery source on the left will "react" to a input current whereas a Cap would simply add or subtract from its current charge.

The oscilator presented by Silvije somehow works similiar to my circuit. I tried adding in series to the transitor another NPN or Mosfet and both will, once presented a voltage on the Base/Gate, will oscilate too. But for that to happen it has to be in resonance the whole circuit. You see, my circuits that I present here are not just "bad" circuits they are in fact transformations of original solid engineering designs that I just work on until it works and voila they no longer seams very logical or correct.

Ah, almost forgot (the reason for this one post). This circuit presents some of the characteristics of Radiant energy, why, because as I approach my body/hand to the circuit the voltage across points Vcd will decrease. Approaching into the coil produces no effects. The area around the transistor is where the focal point is the most sensitive. Now, how is that possible with so little voltage and current? And also, I have been running this thing with this same battery for 3 days now and the voltage goes up and down. When it goes up I try different designs than I see that it does not work and the voltage goes down, so I put back with the design that works (in this picture and the previous one) and it goes up again and the cycle repeats.

ps: S1 on the picture is a switch that I use to "trigger" the gate and cause the locked oscilation described by Silvije .
ps2: photo edited to show correct PNP transitor. Also works with PNP 3906.

@ plego no problem some folks never get it they just pic at whats not there because they can't e inovative har har har   thank you you don't have to tell everything ,,daah that way some onee hass to do some brain farts

I left this baby running for over 24 hours now. The starting voltage of the battery was 6.16v. The brightness of the LEDs are 3/4 of its full potential (at least in my perception). If I disconnect the battery it will show a voltage of 6.30v and after one minute it will go to 7+volts.

When is detaches a 9V battery from the circuit, this it suffers an increase of tension of some tenth of volt.  This makes difficult to measure the residual tension of a battery.

What I have not succeeded in understanding is if the tension 6.16V always been constant for 24 hours ?

@Plengo - "The area around the transistor is where the focal point is the most sensitive. Now, how is that possible with so little voltage and current?"

Is the transistor a FET type?. If so, then this is exactly what one may expect. Anything affected by an electric field can also affect an electric field.

But it is also to be expected to a lesser degree with any transistors. At all frequencies the power of the resonating circuit is still being switched by a very small unshielded package, that is, the transistors. The effects of voltage and current changes are always most pronounced at the point of switching, and is most evident in the arcing that occurs in an extending air gap when switching high voltages with mechanical contact switches.

@Plengo - " When it goes up I try different designs than I see that it does not work and the voltage goes down, so I put back with the design that works"

Have you tried letting the supply battery just keep charging up until it levels out at whatever voltage it may settle on, then use it to drive a resitive load, e'.g. a globe until it is fully discharged again?.  Then let it rise and settle into its residual tension after being drained before reconnecting and charging it all the way up to its highest voltage again?

If you could achieve this a number of times, then I think you might be onto something very interesting here!
P.S. Could you post all the specs on the battery?
