Second Stage Joule Thief Circuits

[innovation_station]

 

im starting to wonder   lmao 

if we cant get thease AG coils to start jumping off the table 


lol

w814

has anyone else figured out the st badge b4? 

the massive kicks are kept magnetic ....  this is your porpulsion sys ..  for AG  find the right freq .. 

probally air core is best sutited   it use natures reconect as electromagnetic radiating push..

i know im off the hook ... lol  lost it some call it ... i personally think i found it 

if this was a huge ego and money thing ...  dont ya think i would have built and sold it ... lol

i choose the truth and now i have it ...  guess thats what ya get when you work at something ...

I just replaced gadget's right capacitor with a rechargeable battery; And charged it.  Oddly enough, I'm not using his circuit layout, simply the standard joule thief with the "Capacitor Appendage" that Gadget added minus the heater wire and switch.  ( i'm limited creatively here ).  Voltage started at 0.988volts and is now sitting at 1.207 down from 1.271 an hour ago when I pulled it off.  Source voltage started at 1.233 and is stable at 1.221.  Very interesting; I do take note that the voltage seems to be dropping as if the battery, charged in this way, is acting like a bleeding capacitor.  It will be checked tomorrow again.

I was thinking that making a bi-symmetrical model ( two joule thief circuits opposing one another where the source for one is the charged for the other - which is the source for the other...thus a recursive circuit ).  Perhaps a DIAC is critically placed between the two and might replace the need for a complicated switching circuit... honestly though, I think a circuit in this configuration would reach a resonance, peak, and hover around the batteries max voltage, at which point they would start producing heat ( the real indication   ).

I have not made the bi-symmetrical circuit yet.



Also, I tested the battery mentioned above after 16 hours at rest and it's dropped to 1.097V..  0.109v gain, and on the charger battery, a 0.012v loss.

Edit, I should add that in this particular experiment, I only charged the battery until it's voltage surpassed the source...this time period was approximately 35 to 45 minutes at the most... far less than Gadget's experiment.

@Groundloop, thankyou for that explanation.

I have reading to catch up on.

Hi jadaro,
I want to point out that you run the risk of reducing the output by an additional 0.7v when you add a second transistor.

And, did you have a light anywhere?
Like did you have a secondary with a led on it?

I am very curious about this part, because my secondary usually goes out if there is something substantial at the C-E junction..
I consider a battery substantial, so I wonder.

thank you.
I think this is very encouraging.

I'll include a picture of the setup.  There is no secondary, only the basic circuit, the only way that I know it's running is by testing the duty cycle and the frequency with my ammeter.  Which was 58.4% and 4.7kHz respectively.  Using the inductors ( similar to what you have in some of your picture ) I can vary the distance between them and alter the voltage and frequency characteristics.  At this point I'm not sure how relevant the duty cycle is ( duty cycle being how long the pulse is 'on' ).

This rather lack luster diagram shows where I placed the LED initially, however, when I hooked up the charging battery, it went out, so I removed it during the test.  I'm not surprised that it did this, the voltage rating on most light emitting diodes is 3.2v, therefore, the battery, having a lower cross terminal voltage invalidates the path as the voltage drops below this - at least, this is my understanding, perhaps a low voltage red LED would remain lit, but then in it's current position, would cause the path to the battery to invalidate, and so on...

On a different note:

There is no secondary in my circuit, using the pre-fab inductors, this is difficult and sensitive, although I have arranged them into such a way.  I'm NOT using a torroid for my tests; I believe that the circuit can be replicated with and without them given the nature of the phenomenon.

Although you are right about the flux remaining within the confines of a toroid, I believe then when OU presents itself, it will be dramatic and obvious.  This is why I alter the nature of the oscillator so that it may be duplicated through different means as to prove the theory rather than simply confirm the peculiarities of a particular setup.  ( Please note: I do not mean for the aforementioned to be inflammatory ).

This is also why I requested, in the joule thief thread, that we post the ohmic resistance of our windings, but this is just an afterthought.

Edit, I'm posting the milliamp usage of my circuit, the ohmic resistance of the coils is 3.8ohms each, with a battery being charged it uses 6.91ma, lighting a single bright white LED, it uses 7.27ma. Although the stated resistance in the picture is 1k, the path to the base from the positive terminal through the resistor is 985ohms, so the resistor is actually 981.2ohms.

Milliamp usage is actually surprisingly low.

@Jeanna, I'm aware of the voltage drops on the transistors and the diodes, I think that the oscillations easily overcome this, though they aren't to be ignore,

i have many osc designs ...  makes for keeping things stable..

great for stage 2

1 osc as many fets as you like  just to properly protect them is important

ist

then you can low volts many amp    go 60 hz lol with the right coil and you get ac ...

NO INVERTOR ..

are there anybody out there that want the real deal ?

i could make it like 1000 ways  eyes closed .. 

w

i was gonna draw a picture of this but i cant find a paper .. errrrrrrr

as everyone wants me to post a schem ..  this will be the first .. i hate to draw on the computer takes way too long ... 

but its simple  i will draw yo many schems if you MUST HAVE THEM! from ME!

how many do you want ...

this unit is called ist PULSED HOT DC TO AC CONVERTOR...   its simple  ..  fire 60 hz dc .. 1 pulse coil  2.6vdc  108 amp  secondary on a toroide core  or pickups as many as you desire...   could be made split mk style ..  or single  eather way AC IS ATAINED!

thank you

HURRY UP AND AWARD THE PRIZE MONEY!   i need to buy cores ... SO I CAN TEACH ON YOUR SITE

STEPHAN ...

ITS LONG AGO PROVEN .... 

OOPS DID I JUST OSBOLETTE ALL KNOWEN DIGITAL INVERTORS ... AND MINE WILL RUN FROM AN AA  JUST GOT TO DROP RECHARGE TIME ON THE CAP   

then get the snake chaseing its tail ... simple kids play

finally thursday i will have the money for the shipping ...  but i still only have the 1 large core ...

i could use 100 of em ...  i have many designs .. 
i will display all my work public in this thred ...

@STEPHAN

if you buy the parts ill build you A BIG  UNIT ..  that you can keep...  you may like to do that .... as were writeing history here ... as usual....  on many levels 

HOLY SH!FT!      YOUK NOW WHAT IM JUST PLAIN STUPID!    HA! I NEED ONLY 1 BIG CAP ...   000000OOOOOooooo LOL  now there getting cheep to build a PORTABLE AC 11O VOLT MANY AMP  UNIT POWERED  FROM AN AA ....THAT USES 5/1000TH OF A VOLT 

NOW  pony what do you think ... 

i dont want to see you picking on my SIS!!  or we will put you back in the barn!!!
