Feedback To Source

[Koen1]

Yes, I believe I have seen something like that at some point,
if I could only remember where...

I was thinking of using potmeters to measure the battery charges,
then using transistors for the switching... but I haven't worked
anything out in detail. There's guys on this forum that can build
a circuit in their sleep, and I suppose they could work it out easily.


Still, you've got a highly interesting circuit there and I am quite
anxious to try and replicate it.

Koen

I was doing experiments with the circuit and I discovered that if instead of disconnecting the running coil by pulling the positive connection in order to stop the motor, we pull out and disconnect the negative connection from the trigger coil the joule thief circuit keeps working better.

So the circuit will have a switch to stop the motor on the trigger's negative wire. When the switch is open the motor stops and the batteries recover more energy while the motor is at rest. When you need the motor again the batteries are ready to go and run the motor.

I dont know if that will damage the joule thief coil, because it will be on all the time while there are source batteries installed on it.

What I know is that it charges the batteries better if you disconnect the trigger negative wire.

Thank you @lowq
Please explain with a schematic your point. It is very easy to say something negative without a schematic to prove what you are stating.
So please draw your suggestion on paint and if it is something with good base, I will try it.

I can do that. However John Newman claims you must use a battery to make this work.
A thought you might look more in to; You cannot look at amps or voltage output versus input separately. To verify the power output versus power input, you must compare the product of amps times voltage at output, and amps times voltage at input. Power is not amps alone, but a product of voltage and amps. Many people has been mislead by the thought that amps alone only matter when it comes to power. Just to "warn" you a bit before you scream "EUREKA!!"

Maybe this video you'll find interesting:

If the person on the video is you. You seem a very inteligent person.
There is a misunderstanding in all this.  If you have been following this thread from the beginning. You will know by now that the purpose I had is to make a pulse motor to run with a 1.5v and recharge the battery while doing so.

Ok. When I screamed eureka I was screaming not because of the newman motor. If you check the circuit again, you will see that the newman motor does nothing to feedback anything to the source.

The newman motor (I will say pulse motor, because any pulse motor works with this circuit) is just the one I had at hand to make experiments with, that do not take too much space.

There is a problem where I live and is that the wind seldom blows.  I bought a wind turbine kit. The wind does not blow. Then I need to device something to be the wind. In this case a pulse motor. The motor will not do any electric generation whatsoever. Who is going to do all the job is the 1.5v runner circuit.

If you take the circuit I posted and eliminate the pulse motor circuit completely and let only its 2200uf capacitor in place. This circuit will (with an old 1.5v battery) charge a pack of 4 1.5v batteries that somehow the charge given to them does not work on a camera to take a photo, but if you put back the pulse motor and run it with that same pack of batteries, it will work.

Dont be my enemy, Be my friend.
We can share information about motors.
I love electromechanics.  I am retired now, but I use to work on an electromechanic shop for ten years.

Again is not the pulse motor what charge the batteries, is the toroid or Joule thief circuit that does the job.

Lets be friends.

Hi,There is a very clever and gifted user on utube called "theDaftman".He has made a battery swapper circuit which monitors the voltage and when it reaches a level set by a pot ,it swaps batteries.He is using it to swap 12v batteries but you may be able to adjust it for 1.5v batteries.Here is a link to his video.You can download his circuit, details in vid.

Also you may consider using a 4 pole double throw relay.If you can find one which latches(these have 2 coils and have the advantage that they don't need continous power.)If you can't find a 4pdt latching relay,you may be able to modify an ordinary single coil 4pdt relay by adding another coil or use 2 latching 2pdt relays in parallel.Hope this helps.
