@jesus
 Theres no reason My circuit couldn't work powering your motor and feeding back . If you wind a regular 40 turn Jt  then wind two more secondaries one with 12volts and the other 12volts ,replace the dc converter  and test run the Newman on the Jt output . you will need variable resistor in any circuit you put a load on to tune it for an output .. Have you tried that ? solder some wires on your pot so they can stick in the holes

Thank you!
The problem is that I cant make the circuit to work from the pulse motor coil output. I am making experiments and already I have the photos that I will post tomorrow.
Another thing is that, in order to accomplish my goal, the feedback has to be to the 1.5v battery of the 1.5v to 12v booster circuit.
If I cant feedback to a 1.5v battery, then I have not accomplished my goal.

@gadgetmall

You are important here too.
The test 4 will be with your toroid recomendation.
Please fill the question marks or write the answers on a post.

Ok let me take a look at that beginning schematic again ... Because the Newman motor is supposed to charge itself . It is Done with two contacts opposites the run contacts. Now i was told the run contact should be as tine as possible just enuff contact to spin then again the contact Just break the pickup contact catches the back spark and feeds it back with a diode to the run battery  much like Bedini circuit . Its the timing of the contacts that make it over unity and run it self . I guess you know that though But i will have another look after My and my little one eat some tomato soup . We have been playing int he snow all morning .. FUN!!

Ok i just rethought this . What if you take the outputs ? ? and Put a Bridge on it then run it back . you probably all ready tried this with similar results of system stopped working ?  Have you tried this mod to your circuit . Look .

@gadgetmall

I tried something similar but the circuit was not the one I have now.
View it here:
http://www.overunity.com/index.php?topic=6362.msg146283#msg146283

As soon as I get the parts from goldmine I will try your suggested configuration. On that order there comes 2 good small bridge rectifiers. They dont take too much space on the breadboard.

@all

Any of you tried smoothing the bridge dc output with 2 caps and a resistor? The bridge output needs to be stabilized to work properly.
Sorry if i am out , i did not get a chance to read everything yet. :-[

Welcome @mk1.
On the answer to @gadgetmall I posted this link:
http://www.overunity.com/index.php?topic=6362.msg146283#msg146283
It is something like your graphic here but without the resistor.
The connections are going to the 12v side, but if you take the positive from the rectifier and connected it to the 1.5v battery as feedback to the source, the motor stopped just right then and there.
When I finish the three tests I am doing. By the way the third is your toroid idea. I have not built it because of the wire price and my recent unemployment. But I will look for old transformers wire. Or just do it with #26 and #30 wire left from other experiments I did in the past.
I will then will test your ideas, @gadgetmall ideas, @spinner ideas and any other idea that can help us to get a true feedback to the source.

In my experiments on feed back the problem a got was the higher voltage by the feedback raised the operating voltage , and killed the output.
I think it needs to be brought down to 1.5v to be effective.

This is a really nice tread you got here!

@ Jesus . The problem i had with My feedback circuit that you corrected the polarity was that it would stop the oscillation unless i put a pot in there to balance ot the feed back to the battery ..Its like the resistor idea of Mk1's only variable because all these joule thieivs are using different wire cores transistors . the best way i have found with all the variables is to use two pots  one on the bias and one on the feedback secondary . as far as the number of turns to get your 1.5 volt charging and running its got to be at least 2 volts higher and at least a few Ma's above the discharge rate . again Mk1 might know the answer . I know on my bedini piggy back coil is puts out 100's of volts until i feed it back to the battery then i read 15 volts on the cathode side of the large diode i use . and it always is about 2 and a half volts above the primary running battery . so i feed 100 plus in to 12volts and it equates to 2.5 volts over the battery and 20 ma over the draw of the system ..

My circuit gives with the voltage divider.98v one way I think that 3.98v the other way. so the high voltage is no problem here.
I know that there is high voltage because the neon bulb lights very brilliant. But when I measure it gives the mentioned voltage.

That sounds interesting. I noticed that when the battery I connect is of some voltage also happens the same you are explaining. It has happened to me too. Just the motor used to stop.

@all
I will post the results I have for the people that are following the thread and finish the experiments with the transformers or joule thiefs. I will test also your ideas and I will post my results.

I do not have fancy equipment. I only have a digital meter and an analog meter, also a strong desire to succeed.

The 555 would not be affected by changes to voltage , When you send more voltage the timing of the core is killed By the change in freq.The resistor and transistor would go,but you need to power the 555.
A 1.5 volt zener diode would be nice , they just don't make them.Any type of system will make you loose some juice.

Thank you. Your comments are very valuable here.
The problem I had with the 555 circuit specifically rhe one shown here: http://www.overunity.com/index.php?topic=6362.msg149570#msg149570 was that it took all the voltage produced and there was not any more left for recharge the battery. I say this because even thoug there is high voltage present, it is almost nothing with a load present, the 555 on this case.

@all

As promised here are the results of yesterday tests.

I took the transistor out from the toroid transformer, put a 104 capacitor at the transformer's planned output and connected it to the 1.5v battery positive. The voltage raised from 1.28v to 1.31v and stayed there for several minutes. After a while it drop down to 1.30v and stayed there.
The rubber band around the rotor got broken suddenly and the motor stopped. I got rid of it and the motor is still running at 1.30v.
After a while it drop to 1.29v. So it is not charging, it is just spending the voltage more slowly. I added a white LED as a charging diode and the situation stayed the same.
I changed the LED for a 4148 diode and the voltage increased to 1.34v, but then it began to drop down as before. It went down to 1.32v after a while.
So this test is not charging. At least the motor does not stop when the connection is made.

The toroid transformer worked without transistor because the voltage and current comming from the pulse motor coil is pulsed by the pulse motor transistor. Also on this way it acts as an inductor coil.

I tried this other configuration of the JtTransformer.
It does not work with only 7 turns as a pickup coil.
It does not give any voltage at the 7 turns output coil.

I was going to try this other configuration of the JtTransformer.
Remember, the goal is to feedback to 1.5v battery.
The original idea is here:
http://www.overunity.com/index.php?topic=6362.msg149796#msg149796

But according to the other tests I have made, no matter what toroid or transformer is connected on the output coil, it does not work properly.

I will begin to plan the other ideas given by the members of the forum. I will make some graphics first to know in what direction I am moving. It suppose to be in the direction of the feedback to the source.
