My goal here is to run a motor with a 1.5v or 9v battery and charge the battery while running the motor.

The question is:
If I have a circuit, like the camera circuit, that increase the source voltage from 1.5v to 12v, How I can feedback to the source battery without conflict between the two different voltages?

Jesus

Here is a simple thought. (probably too simple)

If the source battery is 1.5 vdc and your circuit ups it to 12 vdc, why not feed that to 8 1.5 vdc batteries in series so they add up to the upped source voltage?  Then you would not need anything to step down which would create more losses.  Once the 8 1.5 bats are fully charged, pull out one and use it for the source and put the first one in the series of eight.  Actually, you could do this with a simple switching set-up.  Tie all 8 bats in series but have a lead to each one so you can select any one of them and also include the source.  I am not explaining this right but basically, Bat 1 is the source, bats 2-9 are the destination.  When ever you want you can make bat 2 the source and bats 1, and 3-9 are the destination.  This is sort of what I have been thinking about.  At first, I would use manual switching but later, after you have established that this works (IF) then you can make an automatic timed switching network that would select the appropriate bats at the correct time, once you know when/how often, this needs to be done.

Probably a crazy idea but, when I first started making my Bedini SG motor, this is what I always wanted to do.  I have not finished my motor yet, I keep getting sidetracked by other interesting but related things.

Great topic by the way.

Thank you @pirate

Here is another piece of the schematic as it is working right now.

Even though only a few responded to this thread, the whole thing is this:

Happy holidays!

@ Jesus:

You have this running right now?  How is it working?  Or, are you still building it?  If you have the ability to make a video or post some pictures, I would love to see it, even if it is not completed yet.  I can sort of follow schematics for the most part but, to me, there is nothing like seeing it in 3d.  What type of motor are you using?  There are some very efficient and very powerful dc motors out now for things like the RC market and robots.  These motors did not exist 15 years ago to my knowledge. I can't wait to see what you have.

The motor is running already. I finished it a year ago.
At the moment my photo camera is not disponible but as soon as I get it together again I will post some photos.
The motor is not that impressive, the value is on the circuit used to make it run.
I am using a newman motor. Running it with a 1.5v battery circuit.

@ nievesoliveras

I happened to run across an interesting video on UTube yesterday where someone is using an SG setup with an extra solenoid coil to feedback into the run battery http://www.youtube.com/watch?v=LczzeeyfFoA&feature=channel_page

Unfortunately you can't see much in the way of wiring but he mentioned in another video that he will be making available some drawings soon. 

Regards,
Paul

Wow, that is cool.  He is taking extra power off of the back side of his core.  It didn't appear to slow down his other charging circuit so I guess this is really extra juice for free.  Nice video.

@goat @pirate

Indeed it is a good video. And he states on the more info section that it is a special coil he has.
He adds to it a diode and connects it to the source.
I was trying to do that with the camera circuit. Adding the capacitor taken from it and adding a diode to the output. Then connecting it to the battery.

The problem has been the festivities have got me ocuppied.
I have now to reorganize myself again and begin to make tests and experiments till I hit the jackpot of attaining my goal.

@pirate

Thank you.

I think I found the recipe to get the 1.5 volts from the same motor coil.
It is:
Desired voltage = Coil output X R1/R2

It is been said that this formula gives the correct values of R1 or R2 if you already know the coil output and one resistance value.

I could be wrong though.

@all

This was the last experiment I did.
On the breadboard, the circuit on the left is the supposed Bedini self running circuit. The circuit on the right is the 1.5v to 12v booster circuit. (Could not get it self running)

I must now incorporate to this one of this two other circuits using the formula posted before. I will need to read a pdf file about electronics I got from the internet in order to understand how to properly divide the voltage to get 1.5v to run either the Joule thief circuit or the camera circuit.

Either of them will be used to feedback to the source at least 2v. I know that it puts out around 1000v dc the camera circuit and the joule thief around 60v0lts ac.

I will try to feedback to the source the output of either one without dividing the voltage.  Then I will try with the voltage divided.

In order to understand and for later use i will include this composition of the series resistors explanation.
