Stubblefield coils (bifilar) and speculations

[protonmom]

I should probably ask this question in the jt forum, but will ask it here also.  (Actually I did ask this once before, but never got an answer to it.)
Could someone please give me a shopping list of the type/number for any diodes, resistors, transistors, caps, etc., I would need to make a proper workinng jt?  Also where is the best online place to buy these parts? 
I saw some so-called super caps on ebay but they were those cylinder type caps.  Do we use those big ones, or the flat round ones?  Can any parts off old computer monitors or television sets be used for the jt?  Also, I have Fuji, Kodak, Polaroid, and many off-brand instant cams.  I know there are diagrams for some of them but has anyone tried those off-brand ones?  They would be such names as Walmart, Rite-aid, etc.  I just hate to throw out all those cameras if they can be used.

Also, Jeanna:  Could you tell me again, how to tell which of the Fuji cams is the best one to use?  I don't have many labels remaining on these cameras...just enough of the label to show it is Fuji...so is there some other marking inside, perhaps, that would show me I have the correct one?  Maybe you have a picture of the innards of that one?  Thanks.

Shopping list.
You will get 10 toroids so notice that you can get 10 of everything else. Verrrry cheap.
Allelectronics is my source. There is no minimum and the shipping is flat $7.
Tor-23   10/$1 I love this little guy.
1K ohm resistor 10/$0.50
Get a 1k ohm pot. 5/$1 while you are paying for shipping.
2N3904 5/$0.75
or
2N2222 same price so maybe get some of each.
Plus, you will very soon want at least one 2N3055. ($1.35, I think.)
Battery holders are 70 cents each, but very difficult to make well. I get 5 AAA and 5AA just to have a variety.
They have some leds that are bright enough, so get 5 or 6. Later you can get 100/$9.00 from china on ebay.

Get one or 2 of their small breadboards to save on de-soldering when you experiment.

Electronic goldmine has my second favorite which I use to make real winning MK1 toroids.
It is called a medium filter and is also used as an inductor. It has red wire on 2 sides.
The goldmine also has a cheap toroid called medium.
It is a bigger one that lots of people have but I do not like it very much. It is 5/$1.
The goldmine has good prices too but has a minimum order size of $10, I think, so I usually keep a list going for goldmine purchases.
The shipping is also $7.
Also, I have experienced more delays with the goldmine than with allelectronics.
They are both good places.

Can any parts off old computer monitors or television sets be used for the jt?

Yes, but others need to help here.

Also, I have Fuji, ...  I just hate to throw out all those cameras if they can be used.

They can usually be made to work, but you need to look at the circuits page that Bill put up to get those.
My pic of the right fuji is there too.
Look in the joule thief forum area then choose the one called circuit diagrams or like that.

Briefly, you want the fuji that has the black smooth button on the front.
This camera uses a AA not a tripleA.
Freeenergy found a third fuji so I don't know anymore.
It is one of the main reasons to wind them yourself.

As far a the best instruction is concerned, I like the video from makezine the best.
I remember now, that you cannot watch this, but if you can somehow get to a library or friend's place,
it watch it 3 times then go for it.
They have a pdf at makezine that helps too.

Bill used the instructables one, but I think there might be a mistake or a part that is unclear about the wire connections.
But at least that is not a video.

I am sorry for not answering before!

  Jeanna, thank you very much!  That is very helpful, and now I can start ordering.  I just didn't want to go off in a hurry and order the wrong items.
It looks like I will go with allelectronics.  I have not been to their website yet, but if YOU buy there, they must be good.  (I highly respect your opinion)
Not a problem that my ? never got answered before as we all get so busy.
Well, I will go check out that site and see what goodies they have to offer.  Thank you again!

Additional parts for the JT?

If you want high voltage, a defunct CRT filament tube from a TV will have a high voltage transformer and so will a microwave oven(the  Microwave O ven Transformer---MOT).

These can even be found by the sidewalk or road as junk.  For free.

What I meant was a transformer that gives a step-up ratio in voltage of, say, 500-1000:1 .  Car ignition coils work just as well.
