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.

I plan  on switching to Linux  in the  near  future .
I don't  want  a scope  that  will prevent me from switching .

I am not sure  how well this works ........but it here  and   the Linux community is good at  fine tuning  these kinds of things .

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.

I agree  using  spools  of wire  does not  do a better job than  a  toroid .
What  I was  trying to find  was  a simple easy  way to make  a JT 

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.)

Yes it is possible   to  take   a pulse and  add to it with flyback
I  can  light my  90 LED array   and  have the   battery  voltage and  voltage across the LED array  slowly rising  .  It  usually takes  between  7 and 9 inductors   of different   of several  different kinds to  get to this point .    Feedback to the battery is also  required .
I have been working at  getting  to the self  charging  state with less inductors  ......limited  sucess  so far .
Resonance  is also  a problem ......it is  pretty easy to  get it to self  charge  at resonance ........but  you  will loose  resonance  when  the  voltage  changes  .......so  adjustments to  bring it  back into resonance have to be made every  few hours .

I  am  thinking  about  setting  the  resonant  point   below   the normal  operating  voltage  ...... so  output   of the circuit  would  go up  when the  battery  got low enough  to reach  resonance .   

I remember  Bedini  said that  a  battery  can't  charge and  discharge at the same time .
He always uses 2 batterys  because of this .

I do not think it  needs to be a problem
You  often put  a cap across  the battery .
If that cap is large enough it will act like  a  second  battery .
It will  absorb  the pulses  and  present  near steady current flow to the battery ... either  charging or discharging .

Like you   I think  that  each person following  their  own  path  is  a great advantage .
As you probably know  ..... my focus is on  making  JTs  from  stuff other than  purchased toroids .    and   also  using  inductors  for  creating   flyback  pulses  and feedback to  the battery

If you already have windows you may want to do a dual boot system. You can partition the existing drive or  install a small secondary drive if you have a desktop. This would cover all your bases and give you the choice of what software is more appealing or available. Plus if theres any data on the win machine you need you wont have to hassle trying to migrate it to Linux.

Yes   .......I have  had   a duel boot  system  for  a few years now .
I do not  boot up Linux very much  because  my only internet provided  for the last  few years is through a internet card that is not  supported by linux ......and  probably  will never  be supported  because it  has  been replaced by  a  USB  device.
I will upgrade  eventually ........but it  will cost me  double  what  I am now paying for internet 

I do not  remember  the file  systems that are compatable  with both  windows and linux .....but  I do remember  if you use the wrong one   you can't  get to the files on the other  system .

It is even on the newest version of ubuntu.
I downloaded it first then found somebody referring to it then found synaptic (on board installation app.) would just get it and bring it in plus all the necessaries and install it... and it did.

Yes, I remember

I just got back from radio shack.
I decided to buy a set of spools. They are packaged in narrow spools now, so maybe I can fit more than 2 on my stubcoil.

Right.
I kind of flubbed my explanation yesterday.
I am using the flyback pulses from the jt toroid and not changing the pulses at all at that point of origin.
With the pulses defined and being generated, I am now adding to them with inductors.
I am pretty sure there is no additional flyback, because the new/additional inductors are not part of the switching mechanism.

But maybe your comment is what I need.
Maybe this is the reason toroidal inductors seem to be so good in this application.
Maybe they ARE doing a kind of flyback...

I am glad you restated it. I think it is helpful for us to realize what each of us is up to... and maybe when we add to our focus or change it a little, too.
