@Groundloop,
super dumb question: If I have a pulsating device that is delivering about 40ma for 1/2 hour and it goes down to 39.5ma in the next 1/2 then 39ma in the next and so forth, how long will it deliver 150ma?

I have this new thing now that is delivering that from a 9v battery. I want to know how long it should run until all the power is gone. I really appreciate your knowledge.

[edit: I forgot to give the most important: 20hz frequency at 10/90 duty-cycle. Reason in on the video http://www.youtube.com/watch?v=nii18Imr-A8]

Hi Fausto,
you don?t see the High Voltage spikes, cause they are "sucked in"by the battery capacitance.

If you would redraw your circuit like a normal circuit diagram with the coils at the collector
of the PNP  transistor you would see it better.
The small spikes are still visible with your scope shots, but if you would
reconfigure your circuit you would blow your transistors with the spikes...
Maybe you did already blew your MOSFET with it and this is why only
this "destroyed" MOSFET from your 1st circuit works with it and not many more ??

@hartiberlin
very interesting hartiberlin. I managed to blow 3 mosfets. The ones that are running are the ones that I did not scrow up. So that explains why I got the mosfets and in 2 seconds they stopped working and I was wondering how is it possible with dead batteries with about 3v or less.

Thanks for the info.

Fausto.

Okay, I'm Pretty bummed out. After a long day putting out some fires at work I came home to check on my little units battery voltage and see how it was coming along. Yes the voltage on my unit was still holding out but the LED's are almost so dim that you cant see them. So,  basically the batteries will hold a nice voltage but the current eventually gives out and does not perform any regenerative charging of the battery.

Was about the only thing I thought I had going today, now its not working out very well (sniffle)

Hi All,
if you would introduce a spark gap into the circuit
and use one electrode from gaphite material and
another dissimular metal electrode like copper
you could generate additional charges, that come into
your circuit and be able to charge up your batteries.

This would be the "external" source by using electron clustering
at the spark gap and direct conversion of carbon(conductive graphite)
to generate new electrons as charge carriers and produce external
energy, that comes into your circuit and will charge up your batteries.

Of course this spark gap has to be tuned for maximum
performance,but as in my Newman machine research you will
seeback spike currents, which will charge up your batteries,
if you have the right arc burning at the spark gap excited via
a high voltage BackEMF pulse making the spark jump.

Regards, Stefan.
P.S: I see, that Fausto is already doing something like this
with his burning relay contacts.
but if you will use better contact materials, like copper-graphite
the effect will bemore dramatic and a real charge up.

@Groundloop,
thank you. That's what I thought too. I just wanted to make sure with the words of an EE.

I am playing with my next proof of concept of the N.Telsa 4Switch (I see you are into that too on another thread) and I notice something very interesting. Pulsating with a relay I have a huge difference in the brightness of the LEDs (90+ LEDs now) and it will run for a much longer time. Off course with the relay I have the spark gaps (like Hartiberlin is mentioning) and it really makes a difference.

If anyone see my video they probably will laugh their as*$% of it.  ;D  (Hey proof of concept is just proof of concept, quick and dirty).

I had it running for hours delivering about 40ma until it dropped slowly to 30 then to 20 then to 10ma and still ran for 2 more hours with 4ma and I turned it off because I have to sleep and wife and baby dont like the tic-tac-tic-tac-toc, tic-tac-tic-tac-toc of the realys. Oh boy I am so ready to play with it today. My best performance speed is not what one would expect, not megahertz but mere 20hz (at least it confirms what Bedini said).

Fausto.

@EMDevices ,
                            So after a bit of pondering, I need some input from you guys when you have time whether after the holiday or whenever's clever.  Im going to build a mini tpu and i'm wondering whats the best replication or set of specs thus far to start from. For input a cap or a bank of 5 5.5v supercaps filled to 1.8v full capicatiance and have it be able to power a few led's and have an output for usable power whether im trickle charging a nimh or some form of usable constant dc .  The source of the 1.8v approx 2 ma is our earth battery config and they dont get used up... I kept telling myself man that isnt much juice then a new memeber of our fourm reminded me of a simple point .. the earth battery we have is not a battery of variable resistance its a sink that has a pure charge output so i figured charge a cap bank directly off of it since it has a very fast time constant for filling them and draw from that bank at whatever interval the micro tpu would need to do its thang... Thoughts and design specs would be appreciated and again this is EM's thread so i mean in no way to change the topic here i just figured i could round up a little help when you folks had some free time. Thanks again
                                                                                                    Joe

@ Groundloop
          Thanks for the quick reply i will pass the circuit along in the earth battery thread,  I figured somethign along these lines would be my best chance to get a usable ammt of power from what alone is  just a small unlimited potential... its all how fast ya sample it. Any suggestions are welcome and this can be replicated with just one peice of mg block and a carbon or graphite rod as well zinc and copper work too. 
                                                                                                           Thanks again
                                                                                                                               Joe

Hi All (first post here)

Please allow me to express my sincerest admiration to you all for all your continued quest for truth and discovery of OU for the betterment of mankind, I've read about and tried all kinds of different things over the years and so here is my first post about the closest to near perfect of an experiment I've tried over the years :) 

@ Plengo - I put together your 4 Tesla switch circuit today and so far I am very impressed at the results!!!

I messed around with several different configurations and found the best light versus NO voltage loss, actually the battery is a used normal alkaline 9 Volt transistor down to 7.47 volts for a long time now, but the thing is that after messing around with different configurations and bringing it down to as low as 2 Volts it has sprung back up to 7 and stayed steady for the last 8 hours while maintaining the best light output that I could find without dropping the voltage over time :)

I'm using a BUZ271A Transistor and a coil from an older Bedini SSG (see pics) and got it to work without any fiddling around except for removing the resistor in place of the 2 X 1N4004 diodes back to back on the negative in a + - - + configuration between the coil and the negative feed to the diodes to get a better light off the first diode, oddly I had the same setup for the diodes on the positive side of the diodes but after changing configurations I couldn't get back to that setup without using a 1N4001 and a 1N4004 - + + - on the positive side of the diodes, seen that type of behavior in a couple of Bedini type experiments too, something about spitting the positive (gotta get it just right) ;)

I haven't added the diode setup to the first pic as I'm only working with mspaint here and didn't want to mess up your diagram any worse than I already have :)  You should be able to see the diodes in the other pics.

Merry Christmas to all, may the OU Santa be as good to you as you all deserve and that's plenty lots of  OU EXPERIMENT GOODIES that he can afford  :o

Paul

Hi Groundloop

I know it's hard to believe but I've double checked the circuit and it's as I drew it, the battery stayed stable for over 8 hours when I posted but in the morning I found it to be down to less than half the voltage down from 7.5 to 3.5V.  I made some changes to the original led's in the circuits layout with only 2 LED from 5 plus a couple of changes in the other diodes in the positive and negative connections and it's been running for over 6 hours now at 3.5 Volts without going down, I'll let it run overnight again and see where its at tomorrow.

Don't ask me why but this circuit doesn't behave as it should, after reading some previous posts on the micro tpu where someone mentioned an LED that was installed backwards in the circuit and still worked, I've purposely switched diodes backwards to what they should be and the circuit still runs???  I think that there maybe some leakeage in these breadboards that allows things to happen that shouldn't or that there is something else going on.

I'm attaching a close up picture but unfortunately my camera is only a run of the mill and doesn't take very good close ups, I hope you can see the first pin (PIN 1) is connected to the positive of the battery, PIN 2 is going to the positive lead of the first diode which is also connected to the first side of the coil, that same coil conductor is then going to PIN 3 of the FET. 

I hope that I'm not throwing more variables into this thread than was necessary as that was not my intention, I just had the FET lying around and no other PNP transistors to try so I took several approaches until it worked and after seeing run for such a long time I decided to show it in case it was something of interest.

Speaking of which, I'm off to get some more transistors tomorrow to try and properly replicate Plengo's original and later designs but this configuration sure is strange.

Thx, Paul
