Joule Thief

[Artic_Knight]

Jeanna i wind a big primary bifilar ranging from 25 turns to 50 depending on the toroid and then i use high resistance like 10 k on the base then i try different caps across the resistor . after i see the light get brighter i replace the resistance with one resistor and a pot in series to equal the resistance i found that worked . and i do my Tank circuit with the cap on the wiper of the pot and either end of the pot. Sometimes it works good on the unused end of the pot . sometime the cap works good on the other end  of the pot. after i get the circuit lighting a couple of WHITE leds i add a secondary . One my last unit i wound 90 turns 3/4 around for the secondary . i put a ceramic cap and diode on that in series . I take power off the secondary and i also take power off the primary Jt . I have found that when i  do that the total current draw drops 80% !! . If you need any help let me know . I have two i made this week and they are running on 300 millivolts and 2 millamps with the 04 transistor i sent you . 04 on the end of the number .Another little trick i do is put a diode and electro cap on the C E . This reduces the total current draw once the cap charges up . i run one led off there and the 25 off the secondary . the glow in the third picture is the EC led . It stays lit for about 2 minutes after i remove power . this is because of the electro cap on that junction .on this one i am using 4 capacitors 2 pots a resistor ,transistor ,33 turns bifilar part of it wound ontop and inbetween  the 90 turn secondary . Its wound different in that the collector wire is inbetween the secondary where as the base is in a bunble at the bottom . I don't even thing i could draw a schematic of it tonight . dead tired again .

wait are you saying your disconencting one of the 2 coils on the JT curcuit?  i heard some one talking about a single coil JT is that what your doing?

And???

This is what I see Nathan Stubblefield did.
He always seemed to have his generators in pairs.
I see them as a twisted pair of one copper and one iron wire we called the 5 and 6, twisted like the center tap of our joule thief.
Then these 2 were connected to another twisted pair of the other one.
And there was always this globe thing on the top (which is what I believe to be the sparkler. Inside like a vangegraf on the inside making the make and break.) He said you must never do anything with them... (the red and blue on the bottom and the top = 2 sets of these sparklers which equate to our transistor as in the C and E in the JT circuits)

And it was the secondaries that produced all the effect.


YEAY!

How does it perform?

hey jenna could you pm me with a drawing of that nathan stubblefield generator your talking about if you have one?

that EB stuff is wicked, the wave forms are soo unpredictable and changing, does the frequency change as well? ive got to reference some of teslas work but i think there is something hidden that will release a torrent of energy from the earth and NS might have a similiar idea.

Hi Artic . No i still have two wires three ends for a primary JT and an additional secondary . The difference is instead of winding the primary side by side or litz is i wind the base wire in a bundle and the collector coil in between the secondary . There are other differences shuch as the diode electrocap on the C E section of the transistor and ceramic diode on the extra secondary .. making a one coil Jt is easy you just need to use an inductor (looks like a resistor).

@Jeanna . you need to try a few things to boost the current . one if you can find a 3300 uf 10 volt cap put it across the Eb output . then take your best Jt with one led without a secondary and see of it lights . then if it dosnt hook a little super cap across that setup and wait . then see if it lights up . I made the Pill Bottle Jt for Greg as he has the same problem as you except he can't get a jt to work with a battery or an eb His hard drive failed and hes out of contact for a few weeks . So he is relying on me to show the lights . Its  almost to much to take on . the pressure . . I have a copper and galvanized pipe eb also and it outputs a weak .9 to 1.020 volts and it light several jts up . some dont light some do . the big Eb with the carbon and magnesium is the  way to go . you get chemical and magnetic currents . when the magnetic wave is gone the galvanic takes over . this one lights up a jt without a cap . but the goal of it is to charge an ultra cap and fire off the leds at night .

@ Jeanna,
I managed to post my videos to the MENU, but how do I get a link back to the JT page, say to here. I tried different ways but couldn't do this, help.

I ask you as I see you have succeeded with doing this with yours

Hi Jim,
Sometimes the most unfancy is the easiest.

I highlight the page, up at the top ... the URL
then once back in the reply message box,
I click the globe button and then
paste it into the center where the cursor is.

Remember to move the cursor out of the brackets when finished.

ta da!

That is what I did with your ger trx.

I made a little ckt on a breadboard,
then when it did not turn on the light in the BJTL spot, I added a supercap: 1F 5.5v .
Then when that didn't work, I added the diode and
when that was in backwards, I turned it right and it still didn't work.

...So he is relying on me to show the lights . Its  almost to much to take on . the pressure

Wow, that IS a lot of pressure. Take at least one friend along with you. You will need all of what a friend can do. Shows are really exhausting. You are "ON" the whole time.

.... but the goal of it is to charge an ultra cap and fire off the leds at night .

I like the idea of having the jt being mounted right inside and being run from a galvanized bucket with carbon rod dug into some sand or dirt, so I want to stick with the zinc, and I will change from the unknown shiny yellow metal to carbon welding rod next.

Thanks for the help,

jeanna
