Selfrunning cold electricity circuit from Dr.Stiffler

[Loki67671]

Well finally after a bunch of blown transistors and I have finally come up with results that burn the fingers without blown-up my transistor. 

First pic is the waveform.The probe is after the variable choke and the ground is hooked to the negative.  This form seems to give me the greatest results so far.

Second is the of the Voltage and Transistor Temp ...
15.3 Volts 0.04 Amps
31 C / 89 F

Third is of 22uH Choke
74F

Fourth is of the Neon
145F

At the last is the Board Layout - I have seperated the power input off the board.  The large pin board that I was using seemed to have to much capicitance and I was getting termal runaway on the transistor when the neon was at its brightest.  At least this is my take on it.  I am sure the Dr, has a better explanation then what I can offer up at this time.

You didn't tell any fibs about beating on it until you understand.    I will offer a little advice here and please don't take it wrong but if your scope is in the BASE tank circuit, i.e. attempting to measure the waveforms in the tank, then what is really going on, I suspect, is that the monster tunes up to some set point that must, because the scope is connected there, include the scopes input Z. When you have this running what happens if you disconnect the scope from the base circuit? It will prove beyond difficult to determine what is happening. IMHP you need to get away from the desire to directly measure this oscillator. It is very difficult to do properly even with the finest of test gear. Take the scope out of there and just wind a "sniffer" coil to connect to the scope probe. You can explore with that somewhat but even there the results are not what we would think.    It's not going to be that easy.

I am not trying to discourage you any way at all.  I am trying to offer a little guidance from the master of rebellion, i.e. ME, and say that measurements in this device, as with any other circuit and especially high Z circuits, are very effectively placing the testing gear into the circuit and becoming part of the overall circuit and it's operation. So what we wind up doing is fooling ourselves into thinking we are measuring something but in reality the results are very skewed and not what we think.  I have done this over the years, several times! 

Concentrate on building the circuit as close to the posted diagram as you possibly can. I have caught my transistors, and blown them up too, heading for or actually going into thermal runaway, if they make it to thermal runaway you will know because it's going to fry before you can do anything about it, because I have my tuning way off, or some other factor. That of course is a catch-22. Heat the transistor up and the hfe goes up giving greater gain which of course causes the power the transistor is using to increase thus continuing the process, in a very very short time frame, until we have burned plastic cases instead of transistors.  Been there and Done that 2!

PM me and we'll take some of this offline, if your interested,  to avoid sidetracking the main flow of this thread. I know I'm guilty of the same. What do you want from rebels! 

Best regards and keep at it,

Jim

You might ask yourself the question on why is the transistor going into a super heat mode causing it to destroy itself. You have a one meg off the collector to the base. Without th 22uH connected to the collector, the transistor may pull 1 to 3 mills. So you should ask, what is the added source of drive that forces it to this point. When tuned that energy appears in the load?

You did not state the ambient temp, I like to know the differential.

Smart move on getting the power feed and decoupling off the board.

Place a one ohm in series with the ground leg and then scope that, you will see how effective your decoupling really is and the peak currents, could be an amp or more.

@Dr. Stiffler

  I have been thinking about the theory behind excessive heat observation on neon gas excitation at special frequencies, at given gas volume and pressure. And makes to build a bigger neon lamp and build bigger  SEC exciter. 

   Can you comment on the nature of Neon gas excitation?
   Do you think it is ball lightning happenning in Neon lamp?
   A bigger neon lamp can be used for steam production? And house heating?

   Best Regards.
