Hi Gadget I would like the circuit but don't know exactly how to programme that chip that Groundloop was doing :-\
I already build the charger but it takes quite a long time to charge that Ucap.
Right now I have build the Rosemary heater circuit and doing tests on this.
Thanks
Andrew
Hi andrew ! . Well al the information to build the programmer and the program is here in the last 7 pages of this thread . IT is not that complicated to build a programmer and run the pic program to load the pic code . I will have to build one myself  and if i see a need i can sell the programmed PICs and the max chip . BTW . the max chip can be got for free as a sample from www.maxim-ic.com
.
I have about 10 more boards left after yesterday . I can give it to you for free if you are in the US . If you not then all i ask is postage .

If any other Serious Experimentors are willing to replicate this circuit or the feedback circuit i still have some boards left to give away with instructions and parts list  and all of Groundloops freeware information as well as mine compiled in an rar file for the experimetors who get the Boards . I also can supply you with a PIC programmer pre built if you dont want to tackle that part . they are 25.00 plus S/h  or you can build one . I have some 1500 farad Maxwell ultracaps also still availible on My site .

This is one key point with which I completely agree.
Please the audience to focus on this particular attention.
The fact that there is at the end of the coil Kacher and have agents all kinds elektropotokov (ie kinetic energy) and elektropotentsialov (ie potential energy)
IS WHAT TO LOADING CAPACITORS!


Russian to English translationShow romanization
So:
Kacher is based on the transistor during operation located in the cutoff (at the start of the first pulse active mode then the m-p is always locked.)
Will not go into what is already known.
Consider the fact that escaped the attention of experimentalists.
Workers are the results of the periodic pulses breakdown locked transistor.
Period tied up to the length of the second coil of wire (waveguide) at low power to 1 / 4 lengths.
At high power levels may result in additional nodes along the length of the coil.
The pulse duration is --- or rather the ultra-short.
Receives periodic pulses with very high porosity.
Furthermore.
A single pulse has a continuous frequency spectrum --- almost infinite in width.
But we have repeated series of pulses.

This changes the frequency spectrum - a spectrum of continuous turns in the comb - we have the energy distribution of pulses at different frequencies.
How can emit a lot of frequencies are effectively at the same time?
Linear conductor, even in the usual retinue solenoid pulse is not transmitted are effectively.
The transfer function of demand all conventional emitters is very low.
To send the effective value of the delta impulse in the environment requires unusual radiator - waveguide in which the phase velocity of the spectral signal components much smaller than in normal medium.
This waveguide is a spiral coil.

I'll describe more accessible:
Mentally divide the coil turns will get N emitters of different diameters
Each transmitter has its own frequency response (where N is the number of turns in the coil).
In the spiral coil transfer function for a delta pulse almost ~ 1.
Everything that is valid for a pulse with very short duration tends to 0.
This impact generates a shock fronts of longitudinal waves in an elastic medium (air, vacuum)
So I wrote about it on the branch of "oddities with bits" (p.171)
So if you see where the cone or spiral coil or waveguides is aware of the momentum transfer.
In Egypt, there are pictures wands in the form of a spiral pulse sacred technology (Wands of Horus).
Why sacred?
Because of the momentum effect it hidden super and super opportunities for energy.
Many authors hide it form their designs for this reason.
The geometry can affect the essence.
The fact that Kacher observed eddy processes also do not see eye, but can be attentive, logically understand. About wave longitudinal wave processes around Kacher yet little is written.
If possible, continue with Kacher I will try to lay out Pobol in this direction, because it is not discussed yet no where. Form field around the coils depends on their geometry.

Hi Albert,

I built two of your 650F capacitor chargers and they both work!  One I built with parts on hand and the other I used your exact parts list.  I have been able to recharge the cap above 2.5 volts multiple times with very little drop in volts on my 1.2 volt AA battery.  My only problem is that it takes over four days to charge up from .500 volts.  Can you tell me what the voltage and milliamps should be at the charging points indicated by the red arrows in this picture?  I have noted that when I connect the LED on the secondary that the voltage at the charging output points indicated by red arrows drops dramatically.  I really need to figure out what I am doing wrong that makes this charge so slow.

At what voltage should the LED come on?

Thanks for sharing this great little gizmo.

@All,

Attached is a zipped file containing the newest software for the feed back circuit.
For those of you that got a pcb from Gadget, please use a power NPN TO-220 type
transistor (MJ3055 or similar) instead of the IRF4905 as shown in the circuit drawing.

Also remember to cross the collector and emitter pins on the power NPN transistor before
inserting into the pcb for soldering. Remember to insulate one of the transistor pins with
a plastic tube or similar so that you avoid a short circuit between pins.

Use insulation for both the power mosfet and the power transistor on the heat sink.

Use a small light bulb on the load output. I use two 2,5 volt 0,2 amp bulbs in parallel.
The bulbs is there for a safety reason to prevent over charging of the bcap. The new software
will automatic turn on the discharge to load if the bcap reach 2,6 volt. The discharge turns off
at 2,59 volt.

The feed back from bcap to input AA battery will happen when the AA battery drops in voltage.
This voltage threshold is set by adjusting the variable resistor on the board. If the bcap has
a lower voltage than 1,7 volt, then no feed back to AA battery will happen.

Groundloop.

Groundloop;

Sort of as advertising...What is your opinion; "Is the JT showing overunity?"
Have you tried a normal electrolytic cap. in place of the Bcap. Does the
Bcap draw out more overunity energy from the JT then it would without it?
Does a non-rechargable (carbon/zinc) AA battery work Ok with your circuit?
Finally, can a large normal electrolytic cap. work in place of the battery?
(with inclusion of push-to-start switch before the battery).

I'm asking these questions since you presumably had some time to see
the JT in action. Thank you.

@mscoffman,

It was not until recently that I got the feed back circuit to run OK.

So the testing has just started. I have also worked on getting down the
current usage to the feed back circuit. Right now it is 7mA from the input
and that is WAY to high. My goal was less than 1mA usage. The PIC16F88
is a Nano Watt device, so I'm working on a new software that uses sleep
to get the power usage down. Unfortunately the pic mcu requires an external
clock crystal of 32KHz to be able to enter a low power sleep mode. So I'm
planning to try that out by soldering the xtal on the underside of the pcb.

I have tried a normal (16000uF 25V) electrolytic cap on the output
and the process was under unity.

I have not tried a normal not rechargeable battery on the circuit.
I have not tried a normal electrolytic capacitor on the input to the circuit.

Now to you question:
"Does the Bcap draw out more overunity energy from the JT then it would without it?"

That is what I want to find out, but first the current usage of the feed back circuit MUST be
tuned down to approx. 1mA or less draw from the input battery.

Groundloop.

Thank you again for your comments. Sounds like my thinking is getting slightly ahead
of the situation here; Sorry. Yes, I was considering a dual clock solution for
the microcontroller so it could coast at very low power until it found a specific
condition then speed up to 20Mhz or whatever to resolve it.  Definitely
power factoring. Your work has been excellent so far. Please keep some
of these questions in mind for future comment, if you will.

hello
no high voltage section in this forum.. man what gives..??
this isn't a joule theif .. but it was once the second stage to my jt..

the first video is a bulb lite.. nothing kool.. but it is bright enough

http://www.youtube.com/watch?v=HoLDlTv5YGw

and the second video is just high voltage fun..
but be warned that it is high voltage and could kill.. trust me!!!!!!

http://www.youtube.com/watch?v=n04977vS6b4

stay safe and have fun
