...don't get me wrong, I've been searching long and hard. Today, of course, the experience of 2014, recall is difficult, but the scheme is there, and even a working model, photos and waveforms...
Photo setup and waveform data of the author of the scheme from 2014.
First, the repetition, the Repetition of the first.
The aspirant, went further and increased the size and the voltage source. The Replicator two stable device, with different parameters of the components. This means only one thing - the working principle of the scheme is repeated.
Still a few posts finder under the name "Transistor"
For the fifth day running as a nightlight generator assembled on the circuit is not square. Given the fact that the initial voltage was 2.8 volts. During the day, the battery went up to 3.8 volts and then the battery controller stabilize the charge at 3.8 volts, with a load of 3 LEDs. At least some joy. The forums are a complete stagnation and no progress. Something to start with wow. If you have something interesting to share. Deal with criticism easier than to take soldering iron in hand .
He said, "transistor"? Translate one day recovery system (reverse pulse), charge supply battery from the mobile phone, which is structurally embedded mini controller battery level. This node does not allow the voltage of the battery to rise above a 3.8 volt. For beginners and those interested let me explain: the voltage charge pulse above the level of 3.8 V with a current component is sufficient for battery.

... from the condenser depends on the brightness of the glow.Without it worse .In my case 0.68 UF. Guys how can you talk about the scheme, not collecting it and not feeling it? What would it collect and it is necessary to debug a couple of hours.By the way the first layout works for 8 days kept strictly voltage of 3.8 volts . The layout in armored core works worse. The diode is according to the scheme of the author ...
...Well, what about the evidence=I have the coolest devices out there besides the arrow and the electronic tester maybe it's good. As a result of 10 days I even used to, and native, too, that in the room in the hallway and in the basement all day and night lights.Three generators from not square the plow day and night, the voltage on the battery 3.82 volts in the pharmacy. And when I ran them there, and three volts were not. Interestingly when you shift in the direction of increasing current increases the current transistor and the oscillator frequency and the charging current. Have been working on a new generator in the case of the factory lamp 5 led as a show finish. If all goes well in the future car batteries with a strong generator of this type and with a powerful led lamps for lighting...
...Base and collector windings are included here not as blocking.
Thus without the LEDs Led1 scheme will not start.
Moreover, the opening of transistor base voltage immediately leads to the triggering diode Led1 through the two windings, which are the additional props. One of these windings has a time constant set by capacitor is 0.5*. So that the burning time of the LEDs is determined by this capacitor (in first approximation). Without it, the time is determined by the attenuation of the current in the coil connection.
After Led1 goes out, developing the process of closing of the transistor due to occurrence of a locking voltage on the base winding of the transistor. Led2 at this moment have a self-inductance of the second ring, developed through the revolution of communications and the capacitor is 0.5*.
The charge, "visiteuse" on the transition collector-emitter through the first EADS Tr-RA, then goes back to the source through the same collector winding.
From the usual blocking arrangement differs in that the closure of the transistor is not connected with saturation – no transformer (it is not saturated), no transistor. Closing process controls Led1 according to the scheme described above.
The fact that the current consumption from the source in the opening phase of the transistor is much greater than that of the conventional blocking - at the expense of Led1. ...
This view, I brought in order that the analysis of the scheme is different for everyone.
There is still repetition of this scheme is Not square.
The repetition of the second ( nick "wersila")
Quote: "He is also very Moody to the choice of components. All the same, from 12 to 17 MHz is not huhry muhry. Atpaw second ICE can hand the amplitude to increase , and even more than with the led. The transistor is better to put high frequency. For example, the same КТ3102, but better higher power. I think it is fashionable to do composite-type emitter-follower. In General, the gene class, seven feet under the keel! If you already have two write that the Accu is being charged, then it must be so."
The repetition of the third (nick "AND")
Quote: "On the General wave of enthusiasm, ran a scheme is Not square. Had 30 minutes. Earned the first time. Transistor кт3102АМ. How many will work, we'll see. Not square, thank you!"
My "vision" of the scheme:
I for simplicity of perception painted "transformers" in the core nuclei (cores). In the design we have: the System a blocking-oscillator (R1-C1-L4-VT1) which are structurally placed at the core of the transformer TR1, together with the windings: Bifilar (L1-L2/1) and 0.5 round (L5/1). Actually core sets the operation of the transistor. The second core forms a transformer with windings TP2 of the second bifilar (L3-L2/2) and 0.5 round (L5/2). Have both cores via the L2 and L5 sections which form a common "inductive" communication. How can it work scheme.
When you connect the battery to the circuit elements of the circuit current flows. The current flows in the coil L2 through the two sections and the Led 1 . If the voltage source is sufficient, it will light up if there is not enough, accordingly, will not light up. To the base of the transistor, through the winding L4, so does the current. In the winding L5 , current will only result from counter currents of the windings L2 and L4. there is still a lot of nuances might have, but for a first understanding enough. The incoming current to the base of the transistor it opens. And current begins to flow through the coil L1. since this winding has half as much resistance than two windings L2 consistent, it will be more current, respectively, the core paramagnetics, and through the winding L5, will give momentum to the magnetization reversal of the second core. The current in the coil L2 does not change its direction, and the tension in the string will increase, which will cause the illumination of Led 1. At the same time the current in the winding L3 to glow is in the opposite direction (Yes I was not mistaken. contrary to the current direction of the led it runs, but it doesn't light) . And most importantly, the current in the coil L1 closes the current in the control winding L4, which turns off the transistor. (this element of the blocking generator). At the time of turning off of the transistor, we have "inflated" the magnetic field in both cores, and promise to self-induction in the system. A self-induction, that is, if just the occurrence of the induced EMF, when "the absorption of the self-magnetic field coil"
Due to the phenomenon of self-inductance in an electric circuit with a source of EMF when the circuit current is established not instantaneously but after some time. Similar processes occur in the open circuit, at the same time (with a sharp opening) the value of the EMF of self-induction will greatly exceed the EMF of the source.
We are interested in the processes by opening the circuit. But we should not forget that the current in the circuit will flow in the Right-hand rule (in our case "for solenoid"). Just keep in mind that the current caused by the magnetic field formed in the thread in which conditions are more favourable. It's a closed circuit and the total resistance in the loop. Here in this moment at first glance a lot of controversial moments, but first try to understand. We will deal with regulation of the battery charge.
The basis of charge is a current and voltage. That the current started moving in the direction of battery voltage "external source" must exceed the battery voltage by N times. As resistance elements must be relevant, of course, and the field potential. If the voltage EMF of self-inductance depends on the frequency of the Magnetic induction and length of the conductor which is exposed to this magnetic induction (she is descending in nature), which approximately can be calculated by the formula:
EMF (volts) = In (Tesla) x ω (m/s) x L (meters)
As you can see the current strength we have in the formula for determining the EMF is not! The dimension of the current need to be read by another formula according to Ohm's law for the complete chain, with a small clarification.
I (A) = EMF - U bat. / R + Rn +r0
The dimension of the current will depend on the difference between the voltages of self-induction EMF and the battery voltage divided by the sum of resistance of the utilization circuit. Thus, our charging current is the dimension of EMF is not zero, and battery voltage.
To perform the sufficient conditions of guaranteed battery from us is only good thread with windings L2 = (L2/1 + L2/2). It only remains to clarify whether the current flowing through the led in reverse direction? Please refer to omniscient network request and find such material.
The voltage is 25 volts applied in the reverse voltage will bring the crystal down , voltage 12 – 15 volts in the reverse direction is completely safe for the LED. The operating voltage of the led application in the back doesn't light and doesn't take down the crystal.
As you can see, it's not secret data. The self-induction current in the battery in the diagram are Not square comes this way, and led in the register switching is not lit. In this case, the winding L2 connected in series, act as if the individual components by absorbing each its own field increasing the core voltage. In this register shift
It turns out that there remains uncertainty about the job, briefly closed winding L5 through both core. At the moment of switching the winding L1 with the appropriate direction of current in the winding L5 of a current in the opposite direction, which excites the magnetic field of the second core. Probably it is this combination does not allow the cores to reach full saturation. In the period of the register of inducing the impulse of self-induction, the direction of current in the winding L5 will be opposite to the direction of self-inductance current threads L2, which beneficially affect the process of recycling of the energy stored in the magnetic field in both cores. For each battery voltage, it is necessary to calculate the parameters of the device personally, but that's part of the design.
In my opinion. it is advisable the scheme to be supplemented by two elements: Diode Zener diode VD1 and VD2. If it is a scheme to do large voltage. Well, the circuit of the led Led1 to add the appropriate resistor so that the reverse diode ominal led with a resistor.

Not a square clever, that's why he passed and did not develop further not know. There is only a military option that will examine with the participants of the Project "Source". The scheme can collect any. anyone with the slightest sense circuitry. Soldering iron to hold is not enough, you also need to think about.
