@jesus,

I will have to install photoshop to use my tablet also. I will do it, but in a bit. It is already 4PM and I need to do some things before I can get to it.

I will try once more with words.

Take the drawing you called jeanna's idea. make a second copy of that. Cut off the battery and the 10 r resistor.

On the first drawing add a 47uF cap across the battery.

Move the second drawing into place so the cut battery lines connect to the pos and neg sides of the 47uF cap.

Now, move the line that goes to the pos side of the cap to the battery side of the 10r resistor.

here is the jeanna's idea I am talking about. I will delete this when you have it for clarity sake.

Thanks ,
jeanna

You dont need photoshop. What you need is irfanview and paint. Paint comes with windows and irfanview is free on the internet. Just search for irfanview and the free versio will show up.

Also you can draw it on a piece of paper and take a close up photo of it with your camera.

Also the schematic from @xee2 can be taken into irfanview and converted to .bmp by saving it as .bmp. Then opened on paint and changed. Reopen on irfanview and save as .jpg with the changes done. It is very easy and you will use it the rest of your life.

Also on paint you can use a pencil tool and make rough drawings with the mouse.

Remember it is not giving you a fish, but teaching you how to fish.

By the way I will try to do the changes you explained. The point here is that using one of those given ideas the results are faster for all of us.

@ All:

Another long day on a case and I just got back.  I could not wait to post this, then I will go back and catch up...again.

I found the perfect supercap!!!!!  I have to wait to save up for it but it is the best deal in the supercap market I have found.  here is a link:  http://www.tecategroup.com/store/index.php?main_page=product_info&products_id=18

Get this: 2.7 volts 3,000 Farad....yes that's 3,000!!!!  $130.00 US.  This is only like $40 more than the 650 F caps I was looking at.  Digi-key had a price on a 3,000 F cap that was about $3,000.00!!!!  I am going to buy this thing as soon as I can.  Sorry for all of my excitement but, I can't believe this.  I can charge it with the earth battery at night and or solar during the day, and take it with my in my surveillance van and it will run my phone, mp3 player, recharge my digital camera....anything I want...for a long time.  I'll bet this will light a 48" tube or a CFL for a very long time.  See what you think.  This is a serious commercial unit like the use in trains and heavy equipt.

Keep up the great work everyone!

Be careful because sometimes it says that is a certain amount of Farads and it results tobe les than a quarter of the Farads specified.

@ Jesus:

I am sorry about your friend.  I am sure he will be missed.

Thanks!

Maybe you mean this? (Look at the @xee2 changed schematic.)

Hi guys

I made a second modified camera circuit, used the same B-brand camera,
but the circuit appears to be slightly different... It still looks nearly identical
to my previous one, and it seems to work the same too as I can light an equal number
of LEDs with it and it also powers the small fluorescent tube at the same brightness,
but I can hear the difference.

Really, when I switch it on (now have a working switch attached) it makes an extremely
high pitched sound which is of about the same tone as a tv tube makes, or like a
friend of mine put it "like a dog whistle".
Not many people can hear the sound, I have found that only people with sensitive ears
hear it and most people above 25 don't hear it. Especially people that play in a band
or people over 40 seem to be unable to hear it. I guess it's a high pitch in the same
region as that "Mosquito" device they use to scare off teenagers (what was it, 17kHz?).
The cat also really does not like this sound; he runs off whenever I switch the circuit on.
And in fact, it gives me a bit of a headache too, after a while.

Has anyone else heard this high pitched tone when toying around with a camera circuit?

The odd thing is that my previous circuit does not make the same high pitched sound.
Well, not all the time, that is... When I hook it up to the fluorescent tube and disconnect one
wire, and hold the loose wire in the same hand as the tube, the tube does light weakly
and I can hear a faint high pitched sound. But this is a lot less intense and of a higher
pitch than the sound this 'new' circuit makes.

Also, I have hooked the two circuits to the same battery and tube in parallel and this seems
to decrease the efficiency as the tube lights up less brightly when I do that. This in contrast
to Bill's videos where the tube lights up more brightly when he hooks 2 circuits in parallel.
When I hook them to the tube in parallel with each of the circuits on their own battery, the same
thing happens.
It seems the circuits are not in sync or something. Each one seperately lights the bulb to about
equal brightness but as soon as another is hooked up the tube dims.

As for the classic JT, I got some ferrite rings in the mail but they misread the order or something,
gave me way too slim toroids which are too small to wind a proper number of coil windings on,
so I have re-ordered a bunch of proper sized rings again... ...sigh...

regards,
Koen

     This camera circuit is trying to fill that capacitor with as much voltage as it can in the least amount of time from a low voltage scource.    What it does is it increases the frequency and impressed voltage of the charging of the cap in response to the back pressure of the cap. So as the capacitor voltage rises instead of waiting around outputing a set voltage it increases the frequency and voltage.  Everyone must have seen forensic detective shows on TV with all that crazy variable oscillator noise going off after every camera flash.  The camera flash unit itself is quite a deal.  The voltage ionizes the gas into a plasma which grows across the gas field from electrode to electrode.  When the streamer plasma spans the gap it appears as a dead short to the capacitor.  The current through the seed plasma is so intense that it radiates enough emwave energy to ionize more gas molecules.  The electrons upon returning to naturally ordered electron shells release photons absorbed during ionization.  Bright light.

jesus ....   your a good guy!!



i just know 

ist!

btw im not selling anything .....   it must be safe 100 percent     i think the jt is ok and the cam units as they are already in use main stream ...

Just to let you know, the solar light flowers are available in China for about $5.00 U.S. each. Nice try though.
They also have solar CFL lights for your garden or deck.

I didn't see anything about the earth battery feed, so you might have something there.
