The Circuit look complicated  :)  My last Circuit i was Dealing with a resistance of 61 ohms thru the two coils . I have found building the fan bedinis that two will feed back the other one had over 90 ohms resistance thru the coil . it maintained a feedback but eventually decreased the run battery. the other powersupply bedinies i build all had resistance of 30 ohms and lower they would not feed back so 61 is a number of ohms that will feed back on my circuit . you could try putting a varable resistor between the spot of connection to plus feed back and see if theres a sweet spot it would run and charge  ??  .Just a Thought ... the Neon will not be needed in your circuit as it could Blow something if you let the cap charge up like i did before i put the feedback on thus a big spark . I think you wont do that !!you have sensitive circuit there .

It is not that complicated, it is just the coil output directed to the positive of the 1.5v battery as on your circuit.

I will try to find the sweet spot with a varaible resistor and a 10ohm resistor as on your circuit.

When I tried the circuit with a 12v battery. The motor never stopped, but the battery was drained slowly. No charging.
I will eliminate one neon bulb, the second one, and try with a resistor and a pot to get the sweet spot.

The circuit terminated as it should look working to get the sweet spot.

that top diode should be in series with the positive primary to allow one direction only not to the cap ??
no its not that complicate it just the booster ur using my be blown by my mod as  it feedback high voltage and i didnt want you to burn it out .. . there need to be a way to isolate the primary battery from your converter . im thinking a diode and capacitor array .. just rambling on that thought ..

@gadgetmall

Thank you!
So it should look like this.

@gadgetmall

Pardon my ignorance, but the pot in your circuit is on a different position than on my circuit.
I can be wrong though.

your are going to need two pots . leave the Bias pot there . i was just trying to explain that the resistance of my fan coils may allow me to feedback but your resistance of your coil may be different . the second var resistor will allow you to compensate threrfor a sweetspot between your motor stopping and charging . i always never use the end post on my variable resistors by the way . I dont need the secondary pot cause my resistance is perfect allowing me run feedback without my motor stopping .

Is this schematic okay?

Hey jesus,

Got to admire your unwavering determination..

A thought occurred to me...maybe its been tried - maybe its just a wacky idea, I don't know for sure...so I thought I should toss it out there anyway...just in case it really is a good idea.

What I wondered was...is it possible to charge the battery using a pick up coil...and maybe even do work with the motor at the same time ?

I wasn't knowledgeable about pick up coils and such back I worked on the concept...so who knows...to me it seems half way logical though.

Regards...

I will test as soon as I get a well deserved rest and clear my burned out mind.

That is exactly what @gadgetmall claims he did with his first circuit posted on this thread. He made a video of his work: http://www.youtube.com/watch?v=LczzeeyfFoA

Thanks jesus...I somehow missed that posting.

Didn't mean to steal any of your thunder gadgetmall :)...great set up and great potential.

Its encouraging to me that I was on the right track.

thanks guys . im proud of it and My second self runner charger .the first one Jesus is talking about is here for replication at a thread Goat started Fusionchip's Bedini Feedback to Source!!!  If you care to look . I want to Build a Newman motor Bad I just don't have anymore money to spend as i am unemployed and disabled  . In a Jam Right Now . The Newman Motor i will Build will run from Contacts only . I understand this type is very easy to get to feedback By adjusting the contacts and using bedini idea of capturing the back spike which is way higher that the run voltage .I think it Should work for Jesus on his electronic circuit if the transistor he uses switches fast enuff to generate good back spikes but i know contacts will . I got to go to sleep . Im dead tired too . Gnite .

@all

I assembled the pots as the circuit depicts. The motor did not run. Playing with the pots I could not set the second pot, the output voltage had no change at all. Discharging.
I eliminated the second pot and the second neon bulb. The motor run when the pot was not biasing. Discharging.
I changed the pot for a 1k pot. By the way I was using 2 of 50k that I had available. the motor run very well but I could not find the sweet spot. Discharging.
There is just one spot with either the 50k or 1k pot that the motor does not discharge anymore, but it comes slowly to a stop.
The only difference I found is that the neon bulb stays on even though the motor is off. This is at that spot where it does not discharge anymore. But it does not recharge either.

I need better parts. Exactly the 10k pots needed with wire extensions soldered so it can be set on the breadboard without having tangled wire everywhere.

I will make some more tests and try another approach.
