Big Joule Theif

Slayer JT

Hi Slayer I had build your JT circuit in the past with a 1.5v;2n3055;2n2222 and 20T;20T;480T to light a CFL.
Is it possible to modify this circuit to charge a 12v car battery? Should I insert a big cap?
Any help please?
Thanks

Hi folks, Hi morpher44, I have a ss bedini/joule thief bifilar just waiting for a mod like this. So my understanding from reading his patent is that this shield made of ferromagnetic wire between primary and secondary will enable more diverse loads to be maintained with optimum output at secondary due to resonance being maintained better or that the shield causes less of a reflection back upon the source/primary caused by the loaded secondary. Either explanation would be a bonus for the JT or bedini solid state oscillators. Thanks for pointing out that Tesla patent.

Tesla patent #433702

I was looking over this patent of Tesla's
ELECTRICAL TRANSFORMER OR INDUCTION ... - Google Patent Search
and had this interesting thought.

In this patent, Tesla claims that by shielding the cores slightly,
a magnetic field threshold has to be reached before it fires over
to the secondary. In this way he can create a slightly
longer phase LAG.

If the goal in the Joule Thief is to achieve a nice low-wattage
resonance, and given that the transistor will INVERT or phase
shift the waveform 90 degrees, you want your Joule Thief transformer
to also phase shift EXACTLY 90 degrees for whatever resonant
frequency your shooting for.
By constructing a transformer this Tesla way,
it might be possible to achieve a constant-current on the
secondary -- allowing for additional LOAD to be placed on it
w/o altering the resonant frequency.

Anyway, for those Tesla geeks out there, take a look at
this patent and see if it "sparks" any Joule Thief ideas.

Hi folks,
I was watching Lidmotor and Jeanna's videos earlier, LIdmotor's "Lightning Maker" and Jeanna's Multiple Secondaries,; and something dawned on me. Why not take 3 to 6 joule thiefs and put them on a torroid evenly spaced, pulsed to rotate, and then put the collector secondary around the whole thing, all 6 170volt tiny 4KV Trigger Coil thieves (armature) acombined on one collector. Well, it beats Stan Meyers Iron Gas bull****, and it's likely what Steven Mark was doing. Hey, take it one step further than that, and use the 6 thieves to pulse 6 lightning makers mounted on a torroid and wrapped with a collector. Hail Tesla! Maybe not major amperage output, but that's not needed if you use the kv pulsing (rotoverter) big caps, instead of heavy amps. Well, just wanted to put this out there.
Mike East...

Finish it. Allow 30% of the core to be bare and then wind bifilar 2 / 8. Then when you find the "Right Stuff" a comparison will be enlightening ;-)

I noticed that I put one too many 6's in the part number, it's G6683. The advert says they're from Nippon Ferrite but I can't find anything about this company on the web.

But I did find a list of Ferrite manufacturers and distrib's, many having catalogs, and at the very bottom, a link to DL5SWB webpage with a program for toroid and inductor calculations and design.
WORLD WIDE FERRITE MANUFACTURERS

I have so many JTs driving LEDs that I don't really have any real reason to drive a CFL.

[jeanna]

@Jeanna---SUCCESS!!!

yeay!!

I started messing with it and tried adding a second then a third transistor (2N2222) to the circuit to HOT ROD the thing. It is like putting a bigger carburator on a car engine. It eats more fuel (higher higher voltage and more amps) but the perfomance goes up.

I saw you did that on something else. Is this just what more silicon will do?
I have seen that the physically larger transistors both take more amps and produce higher volts, in the same way you are describing this.
It could be an interesting way to fine tune the amount of amps juice needed to run the dc part of the circuit.
(But, at this moment, I prefer using the rheostat to control the amps draw.)

Thank you,

I will check out the video.

Happy New Year

Here is a video from Chilliqueen on youtube.

YouTube - Super Joule Thief - RLC resonant circuit.

It's another JT circuit very interesting design.
Looks like a must try.

@Slayer----We think so much alike. A YouTube viewer contacted me and gave me a link to one of Chilliqueen's other videos and I ended spending an hour watching his videos. This particular one I favorited and is a must try simple circuit. I really like the way that he is experimenting with electronics and showing how this can be learned with a few components, a piece of cardboard, and tape. Thanks for posting it here. Maybe we can get him to join in the fun at this forum.

@Jeanna---SUCCESS!!! I got the little toroid wound and it works. I just wound 3T, 9T, 110T with the 110T wound in two layers. It is all "green" wire. It lights up the LightsofAmerica bulb (still unmodified) on a AA. I started messing with it and tried adding a second then a third transistor (2N2222) to the circuit to HOT ROD the thing. It is like putting a bigger carburator on a car engine. It eats more fuel (higher higher voltage and more amps) but the perfomance goes up. This is Dr. Stiffler's idea and after I saw what it did on a JT I stopped and tried it on my old SEC 15. I made a video of that but didn't post it here because it didn't fit in anywhere.
It is at my channel.
Happy New Year!!!

@watson

I started to wind a lot of turns of 32 gauge wire on one, but it's tedious and I didn't finish. I don't think I have anywhere near a hundred turns. I may try to wind some primary and feedback winding over it and try to drive a few neons or a CFL something like that.

Finish it. Allow 30% of the core to be bare and then wind bifilar 2 / 8. Then when you find the "Right Stuff" a comparison will be enlightening ;-)
