Joule Thief

[Mk1]

Just a hello to all.  Finally caught up on the reading in this tread   WOW!!!!!

I was intrigued to this tread when i saw Lidmotor’s post on the JT  Resonance Effects For
Everyone To Share . Then saw Pirate’s lighting  400 led’s

Jumped out of my chair, ran to the one and only Fugi camera in the house and tore it apart.
After trying to decipher the circuit found Jose Pino's site and proceeded to de-solder parts off the
board. Anyway hooked up a modified CFL pushed in the battery!!!!  arms, Fugi board and CFL
went flying through the air. After modifying another CFL and carefully putting the battery in I
had some great light.

I normally do not join the treads and reply, and do not have anything to contribute as yet.
But as you all know there are a lot of us out here following, doing and learning as we go.
So a hardy  THANK YOU ALL and who knows maybe I’ll come up with an idea to share with
you.

I truly believe that man’s salvation is when we learn to understand one and other and share that
knowledge .  However as bad as it is!  “and this scares me” it will probably get worse before
most learn to understand.

Hi , RAF , welcome , you did good registering, you get a chance to ask question and increase your chances to get it before its to late, and yes i am sure that there are many of you guise out there.

You out there , come join , we are all needed !

@ RAF:

Thank you and welcome to our group here.  Good job on your Fuji.  Please feel free to contribute anything that you think someone might find interesting.  This is a good friendly and helpful group of folks here and the more of us, the merrier.
Welcome.

@MK1:

Thank you for your tuning explanation to General Jim.  That was very concise and informative.  (I am printing it out to save)  You explained it so well that I think that even I understand, ha ha.  That is great information for our group to have, thanks.

still playing the the green unit ....  i have it liteing the led on the jt  i then put a full wave bridge rectifier there i made from 4002 diodes

so it lights the led i read 1.95 vdc off the bridge

i have a led across the secondary ....  it is lit ..... i also have a led across the feed back winding it also lites ...


i added a magnet too it adds more to it .... and when at the right distance i notice a big jump on the bridge ...  im building more bridges for all other coils ...

ist

here is a pic

now i cant stop blowing leds on my secondary with  leds lit on other coils


i took another pic for you guys ....  i added a neon   it is lit too and my recharge voltage went up now it is 3.5vdc  feed back out got brighter 

jt led went dimmer ...

@ Timmy1729

Does anyone have any idea what motor he was using in his other two videos? If it is in something
I have at home I will use that. If not, I am going shopping later anyway.

Tried this a while back it is a dc motor with one of its armature pickups broken off.
This causes a dead spot in the armature windings, and gives a pulsing affect of the current from
the battery.

“Note when i did this i used a unmodified dc motor “ so maybe the pulsing has some thing to add
to the setup.

Hope this is what you wanted to know. If so i would use a dc motor i had laying around rather
than buy a good new one

well looks good i just added the last led


on the 2nd feed back coil ... it lites aswell   all are lit  and i have rectified 1.5vdc off jt side ...    i need to make new bridges i will make 4 of them

jt side it will be 4001 diodes hv side secondary   will be 4007 diodes    feed back coils will be 4002 doides   for a total of 16 diodes

i will add a picture when it is finished and see if i can find enough meters to tap all outputs to get voltages ...
