Hi,

How did you came up with the bifilar, aluminumfoil covered toroid wire?

Did you meant that the source battery voltage is fluctating, or is the voltage fluctating up and down between the source battery and the charged battery?

It is great that you can charge a battery from a sourche which is not decharging (It will keep me awake for a few nights thinking on how this is possible). So if you place a volt meter over the 1,5V battery, it will read 1,5V for two days straight without sign of voltage drop while you are charging the other battery (Unless the source voltage is fluctating)?

Can you place an amp-meter in series with the source battery, and do the same with the charging battery? Just to see how much amps there is flowing through these two batteries (Considered the knowledge about the voltage over each battery). If you have an "average-switch" on the two meters, you can for a period of time see the average current drawn from the source, and the current which is charging the other battery.

If you have time, you can also make a watt-meter. You can find these analog "bulk" meters on ebay or something. The needle in this analog meter is driven by an electromagnet in stead of the moving magnet you find on analog amp, or volt meters. The stator is also an electromagnet (As usual). So you will never read any values unless you have input on both electromagnets. Basicly it is both an amp-meter and volt-meter in one operation - also with at least three wires for measuring both amps and voltage at the same time. The scale is therefor logarithmic. Perfect for reading the power in true-time.

I hope you don't think I'm fooling now. I'm serious about these questions and ideas.

It does seem correct. Just remember to take one bare wire from one side and one covered wire from the other side and join them. That is the joule thief center tap. There should be one bare and one covered left. It is just as a bifilar joule thief toroid coil as your drawing.

That cable you show on your link is not the one I used but if it has bifilar strands inside it can be used.

The one I used was taken from the cable that comes from the source power of the house to a monitor. When I opened the discarded monitor there was three aluminum wires around a long toroid and I saw that the cables were comming from the cable mentioned.

That was what turned on my inventor's mind. I asked myself, what would happen if I built a toroid coil with it, and the rest is history thanks to @pirate's counseling about the battery conditioning needed....

You simply are not reading the thread.

@all

Because we are going to use super capacitors eventually, I got this information about them.
I will post it here for later reference.

@all

I found this circuit interesting. I will include it here as a possible self runner. The inventor claims that it produces its own power and feeds it back on a loop. I think that it deserves a try.
It is a joule thief coil circuit, divided onto two coils. I mean a two coil joule thief. Instead of the bifilar coil, it has the same connection with separated coils. It uses no battery is the claim the author has.

There is a lego version that says that it is not true.
Does anyone has done it?

Jesus,
Just a thought: leave out the transistor and resistors, simply connect the two coils one to one with the right polarity and align the two coils in the right way (90 degrees +/- a correction to solve timing)

Question: what will happen when one uses different coil values ? Nice puzzle......

Such a construction starts to look like a coil version of the WipMag motor by the way

Maybe we should start a separate discussion thread on this

Thank you @robbie47.

There is a topic about this already!

http://www.overunity.com/index.php?topic=6829.0

There is one member at the end called @vince that did one without the resistors, only the transistor. He needs our help. Lets see if we can help him with positive counseling and ideas to see if we can solve the problem that the coils does not generate enough voltage and current to activate the transistor.
