Joule Thief

[jeanna]

I need some help and advice since I am unable to get this working.
Could someone please verify and correct me where I am wrong.

Thanks
J

can you put a pic on here so we can see?
I agree for the first troubleshooting reverse the led.
Double check that the bifilar is connected right. You need to connect the end of one to the beginning of the other for this to work.
Have you watched the makezine video on youtube?

If you have not yet, I recommend watching that 2 or 3 times then dive in.

Is that an american transistor?
I think it is not. That means the placement of the base and collector/emitter pins are in different spots.

BTW, welcome to the joule thief forum!

I just put this on the downloads section. 2MB

It is a must see!
You can even hear my voice. I got pretty excited, you'll see why!

Here is what I have been working on lately.  I'm getting very interesting results on sinleg turn tap windings.  169vdc on 10 turns on the b/c coils and 8 on the pickup.  I was also using leds which showed interesting stuff happening.  Yes the LEDS are coming off the b/c's. not sure if anyone has done this but it's pretty cool.  I divided the pickups so that I could put that gain back into the circuit....nice increase.  It will light a neon too.

This is using 1.5vdc@.15a but goes up or down depending on what I play with.  oh yeah...really low resistance somewhere between 0-30ohms.

@stprue

That looks great. Now I must know what type of camera do you have?

Hmm,
You ought to be showing us the results of a stepdown transformer.

?

I know you can get surprising results from a single turn pickup/secondary, but 169v is stretching my sense of reality.
Not if you had even 40 turns, but one turn secondary and 10 turn collector/10turnBase primary?

What do you think is happening?

Anything could be happening today. I found some radiant energy from a joule thief, so why not 169v on a single turn secondary?

pretty cool.

edit:
Oh, I see 8v on the pickup
169v on the C-B
So, is that transistor action?
Are you reading this across the C and B?

i just thought i would inform the public ... 

b4 someone tryes to rip my work off...  that im doing ...

cuz im poor ... 

im makeing POWER POINT demos FOR THE ELECTRIC CAR INDSTRY ..  FOR A POWER SUPPLY ... 

as well as i have ideas i also have dreams of 1 day makeing it in this world ... 

so i must stand back and SAY THANK YOU TO STEPHAN AND EVERYONE INVOLVED ON OVERUNITY ...

this site documents time and date of ORIGINAL IDEAS ... 

portection for the poor ones out there ... 

of course when i perfect my design ..   THOSE THAT HELPED ME I WILL IN RETURN HELP THEM ...

PEACE ...

BUILD THE LAST UNIT PROVE IT WRONG ... TOO    AGIN YOU CAN NOT!

WILLIAM

btw theres where your 1/4 wave length fits ...    tapping the harmonics ?   might that be ? 

i have seen many bands on my scope ...  some i assume are voltage and some are maybe amparage nodes ..

i just got done drawing up my 6 phase 2 freq pnp npn in sync  ring .....  wow i dont even know what to call the darn thing ... 

lol

so there will actually be 12 jt coils as primaries .. 3 pnp and 3 npn per phase all wound same dirrection ... like the 5555 coil

i will likely use 5 turn / per  only 1 lap ...  as my cores work well with 5 turns ...

it is a 1.5 k core .. grey feroite 5 5/8 "

the goal of this unit is dc output .. to a BATCAP.... lol

of course ill only build it from a few aaa batteries for now till i have a BUNCH OF ENGINEERS  ..

i like to play safe ...

i wound a simple unit to show half of my advanced unit i just spoke of ...

first picture is half of my first phase .. this is npn ...

second picture is npn pnp 1 phase ...  i will dubble this for 2 phases .. but im out of room on this core ... lol

i did this to show how my simple advanced units will operate ..  sure i can do this in the mk2 winding unit ... lol i already have it drawen in pencil .. 

hows that for retarted lol  48  jt wires ends ... hummm   12 transistors 2 3 led chasers ..

you can see plainly how simple it is ...   

key toroide tuneing .. wire length mass to mass tuneing phaseing flip flop ... bla bla ..  lots too it but

seams damm simple to me ... 

Hi Ist and Everyone . I have not logged on in a while . I got My Digital storage scope and have not even unpacked it yet in a week . I have been experimenting thought in between daddy stuff / beach vacation and whatnot . .
IST this Cncerns Open Source . I have a Patent Pending on one of My Toys i sell and the patent office says open source is not worth PooP !! Anyone anytime can steal your idea and patent it even though you might have posted the information years ago . ITs a FaCT !! So if you dont want it to be free and make money then dont post it cause some one with money will steal it and there is nothing you can do about it . I have a provisional patent on  My E-Light and have already Bought the Eturinitylight.com Site . To patent somthing you have to have a patent search Done By a Lawyer . Its 399.00 Dollars Us .. Then if your not stepping on anyones Toes the provisional patent is issued for one year for 299.00 Us . Then you can make Deals with Manufactures to Build and Market your idea and Collect Royalties and still own the patent . Very Expensive !! But i just wanted you to Know that Open Source Is a place where ANYONE can take your idea and make it there own if they have the 700 bucks !! JFYI . My E-light is My own Circuit and I did not steal it . I plan To make My Daughter a Better Life when I get to old to move and see . So far the patent search on a 1 volt three led self recharging spare battery using dead batteries is looking VEry good . No one has it . BUT if i didnt have a provisional patent Someone could steal just the Idea and patent it . They Don' t even Need a working Model . They can Patent the Idea and you will not make a Dime if they Do . 

I have Learned a Lot From My Patent Lawyer .Take Heed My Information . No i wont take your ideas but someone could . Anyways . I Blew up My lab tonight with an hho drycell and a new torch tonight . What a Mess and LOUD!! . Im still shaking but ok . It just Blew potasium Hydrox all over everything including me and busted My Brand New Bubbler tank:( . damn . on a good note i have a Cool Jonnydavro selfrunner/SelfCharger  that has 5 small coils on it all running leds and Jts and High Watt leds from 1 milliamp at 2.4 volts (ultracap) .. A Video Shortly when i can get the time to upload all the Vids i have been Recording . . I must catchup now as the last post i read was somewhere in the 600'' ahhh.. Peace and Sorry for My Common Off topic chatter but its the most read thread  and My Friends are here .
