Joule Thief

  if you took off  your  original  secondary  and  placed  3 or 4 spools of wire  on the  coil just like the  first  red one ...... you might have  pretty good output .

I agree. I have used the full spool and it is rather good. But my hand wound toroids are as good.
I would need to buy another 3 pack to add more. I probably will.

If you have 2  doors  that open at the same speed .........but  one of them is 10 times  bigger than the other ..... 
you can move what every  you want to move through  the large  door  sooner than you can  get it though the smaller  door .

I like that bigger door metaphor.

Here is the thing for me.
I am starting with volts and pulses and making more volts with pulses.
It is very clear to me that raising this voltage to a much higher amount would take much fiddling, but that is basically all.
...to start with a pulse and to increase the flyback to usable amounts.

I am letting others devise the battery charging set ups, as you know.
I saw in the second video linked by MK1 today that bedini thinks that putting it into a battery is the only way.
I like how he said that the chemistry of a battery changes when treated to this kind of voltage, but I do not think it stops with a battery.
I have nothing against a battery especially after what I heard from bedini, but I think there will be a way to make usable ac (pulsed dc) from magnetic pulses.
I believe there is a way to increase the output from a given input of pulses.

But I will not be making the whole unit.
We are all sharing our ideas and we are all making a combined creation.

I want everybody to follow their own interests, because as we do that these elements will all pull together to make a terrific whole invention.

(I am living the future I desire.)

Hello, does an 10 MHZ oscilliscope tell you on the screen... things like AC-voltage or DC-voltage from Joule thiefs ?
or such as frequency etc.
Or does it just have lines on the screen???

The battery for this scope is $60. You can buy it later if wanted.

There are cross platform scope software.
If push comes to shove you can always do a dual Os boot system if you have a windows Os also.

One thing lacking was a utility to "null out" 50Hz or 60Hz, but mabe scopes dont have this, but sound jockies can get these things to stop mains hum from being a problem. Hmm now you got me thinking.....

The shorter the probe cables the better.  A dedicated circuit for the scope is the best way to go as long as the ground wire is on a separate ground bar instead of being hooked to the common neutral bar. A neutral wire is a hot wire and you can pick up transient spikes off the neutral bar from any other loads like refrigerators,mixers or anything with a motor.
Cheap soundcards for audio is a different story. I have a dedicated outlet for recording Audio using star grounding. I still picked up hum from the Computers soundcard. I used a hum eliminator to get rid of it.

Mine which is a velleman scope called HPS10 gives you the choice of which items to display. You can display ac and dc if you want it to.

What you will see on the scope is a moving drawing of the pulses over time. In most cases the moving part of the drawing is too fast to see it drawn out and you see a bunch of spikes jumping or rolling, but that has to do with the speed of drawing and your eyes among other things.

You can display the lines if you want them or not. Even if you do not display them there is a time/div read-out which is your essential read out and it will be shown based on those lines.

For instance you might have 4v/div. So where ever the line dividers are, they are 4v apart. But I never show them because there is a digital read-out that tells me the ac peak to peak voltage which is what I use.

I use peak to peak because I am interested in the peaks and I can see if they are spiky or smooth.

We are using spiky and the thinner the spikes the better for our purposes.

You find the frequency by putting markers on the wave at the same place+1 of the wave. This will tell you in Hz (cycles per second) or  length of second between the markers. It is written right on the screen.

I hope that answers some of your questions. It took me a while and a lot of help too.
