Testing the TK Tar Baby

[TinselKoala]

Now.... originally it was believed that the FG might be supplying power to the circuit that went either into the load heating it up, or back to the battery keeping it from discharging. So it was suggested that the FG be isolated, which I tried with optoisolators. Result: isolation achieved, mosfets switch perfectly and no oscillations present. So I finally built the 555 circuit, but it seems that the main issue is still unresolved: the power supplied to the timer gets mixed into the mess in the Tar Baby main circuit, and even appears to be necessary for the oscillations (by providing that source bias current).

Right now I'm kind of stumped. How to drive the circuit with the timer (or FG for that matter) to make oscillations superimposed on the signal, with controllable pulse parameters, but without injecting extra power into the circuit?

I mean, once again..... it's a case of being able to duplicate her raw data but differing about the interpretation. It seems possible at this point that perhaps the circuit _could indeed_ have run continuously in the q2 oscillation mode, heating the load to perceptible warmth like the 50 + degrees C given in the video demo... without the batteries running down very much at all. But NOT because energy was coming out of the superluminal zipon flux, but rather because all or most of the heating power came from the FG, not the battery.

Perhaps you haven't seen this circuit of mine? It does what you are asking for, and is what I will be building to demonstrate COP Infinity.

Hi TK,

Sorry but I have no any connection with that video, I stumbled upon it accidentally.

Gyula

Well done, Gyula. I'm glad you posted that...

What did you discover about the 555 circuit? Did you have to make any changes from the original published diagram in the Quantum magazine article? I'd also like to know the resistance actually used in the series gate potentiometer... I always wound up running mine at almost minimum resistance. (You probably know that I did a lot of work with this Ainslie circuit a couple of years ago).

You got very little heat in your load at Ainslie's reported 3.5 or so percent duty cycle. Try flipping the duty cycle exactly inverted to 96.5 percent ON, and see if your resistor heat profile matches what RA published. Mine did....... 

What's the scope app that you are using? Does it use the sound card for input? I've been looking for a good scope app that will run on Linux (and is free... of course.....)

Thanks again, that was a blast from the past !

@Gyula:
Oh, well, thanks for posting it anyway. I've favorited it and I'll post my questions to the YT comments section, maybe the originator will answer.

@.99:
Yes, I'm aware of your neat solution and I intend to build your circuit too. Very neat by the way.  I'm going out to the component supplier today to see if they have finally received my inductance meter, and they should have the TC4426 in stock, I hope. Also I hope they have gotten some more PG50s.... somebody seems to have cornered the market around here, they are hard to get. I wonder if the cholos are using them in their stereo boot-rattlers along with those big 5-Farad electrolytics.

But really.... you and I both know that the "main suspect" will never never in a million years acknowledge that results from such a "complicated" circuit could possibly resemble, or falsify, hers. ("My circuit simply has no long wires or curly things or terminals or capacitors, Poynty Point, and this has been verified over and over by seven collaborators and an entire boatload of academics. Therefore your argument is invalid. Warmest regards, Posie Roaster")

That's why I want to try to use as much of her original circuit (whichever one) as possible and make some kind of "dropin" module that could simply replace the FG without the power injection and yet preserve the oscillations. That might be impossible, even though I was able to do it 2 different ways using the baby 2n7000 mosfets (cap coupling, very simple, and the optoisolators worked too).

TK,

That variable oscillator I designed around the TC4426 doesn't have a very wide range of frequency or duty cycle adjustment. It's just enough to play with things a bit and provide an adequate drive to the MOSFET. Feel free to use your FG or 555 there instead if you do build this.
