@all

This obsession of mine to get feedback to the source has been very expensive for me. On the last test the four LEDs got shorted. I dont know why or how. All were in series.
I know they are shorted because they do not work on their respective place on the 4 different transformers joule thief and they have a reading both ways with the ohmmeter.

@ Jesus:

It is very easy to burn or short out an led....trust me, I have fried many.  Especially the small 5mm ones.  If they call for 3.5 vdc and you feed 4.5 or 5 or higher vdc into them, they burn bright for a short while...then ....poof!  My guess is that you are feeding more volts (or amps) to them than you might think.  This is just a guess though.  It might actually be a good sign.

Thank you @pirate. I will wait for the goldmine parts. they havent come yet. There is no LEDs on the order though.
I need a job.

Good job on your video! (5 stars)  That was quite a spark when you hooked up the positive output back to the + battery terminal.

Hey Guys Thanks . I can't see why anyone else can't do this . I think its possible the 48 volt fan Might be giving the Extra energy ,more turns in a bigger package . you can get em at gold mine for 2.75 . i bought three. Its a  toy because i can only make the fan run forever but not actually use the power from the Secondary for anything else. I'll Just stick in on a Shelf and Let it run and when some one ask What is That Chirping  i'll show em. I might have the same problem i have with the Big Selfrunner in that it might cook the battery over time ..

Never saw 48 Volts Fans yet,
please specify part number and post a link
where it can be bought online.

Many thanks.

P.S. How long did you run it already with a dead 9 Volt battery ?
or can you already run it just with charged supercapacitors
without any battery ?

@ Stefan:

That was going to be my next suggestion....see if it will run on decent sized supercaps with no battery.  I did that with the joule thief circuit and it works well.  If anyone is interested, I posted a link in the JT topic to Digi-key (where I get my supercaps) and it shows the ones I am getting next.  2.7 volts 400 Farad,  about $30.00 ea.

@gyulasun

I made the changes and made the tests. When I added three LEDs the motor kept its slowness. I then added a 2200uf cap and the motor accelerated a little bit. But it continues to be slow.
The charge does not improve. Maybe I am doing something wrong. A photo and a schematic is included. The battery is disconnected.
I had to put a contrast wall behind the LEDs in order to see them. That paper does nothing to help the circuit.

Jesus

Hi Jesus,

Very sorry that my suggestion did not work as expected,  I based it on your measured circuit you included in your Reply #143 a bit earlier. 
I think the basic problem is the diode bridge connection directly to the Bedini output, a kind of isolation would be needed,  probably a third coil wound directly onto the pulse motor's presently 2 coils could directly drive the diode bridge, giving an ground-independent output  (i.e. the bridge cannot "see" any other voltage or current galvanically from the rest of all the circuits). 

rgds, Gyula

@hartiberlin
Hi . This was My 9th Bedinipowersupply .I gave them Away for Christmas ! you are talking about the first one . The one with the 48 volt fan is running off a 12volt battery and Just Built last night .  . .
yes . i will get a number for you but this is Jesus's thread and i just posted My latest Video for encouragement for Him and His Project. We can Discuss It on My Thread Started By Goat` : Fusionchip's Bedini Feedback to Source!!! There is a picture of My fan Back there !

@Pirate . I will Try that . So many Things I was Asked to do with it .  Thank you Guys and Thank you Jesus for the Space here .

@jesus

Your alternator project , if you recoil it with soft iron coil , you will reduce the magnetic pull and reduce friction , This is a old story that most won't even try.

I have not had good luck lately.

Dont worry, I am just learning here. If it can be done I will do it.

I am trying to obtain a circuit that converts the alternator on a motor, but I forgot where I saw that information.

@mvmcman

Thank you!
You should make your posts on the thread not on my email.

I received @gadgetmall feedback to the source circuit. I made some small editing and post it here as an example of a working circuit and as reference.

@gadgetmall

You are always welcome on this thread.

Jesus

@all

I tried this version of @gadgetmall circuit and the results were not different than the results from the circuit with the rectifier.

I used a flash circuit cap 300v 80uf and I configured the circuit as the graphic.
When I try to run the motor with all connected, it does not run.
If I disconnect the wire coming from the output coil to the 300v cap, the motor runs.

This is a crazy situation I have here.
