Stefan,

I used SCR because the low trigger voltage and current needed to switch
them on. The very low voltages in this circuit demands components that
can work at this low level voltages. I will find a solution.

Alex.

Hi Alex,
Here is a site you might find useful, they have many different types of switching circuits, and it's all open source with clear schematics.
There is also a way of working with these guys to develop the circuit with your requirements,
this is a very big site and hopefully will have what you need.

i add

if you wonder why i have not said any more bout my SUN CIRCLES...

it is because there is a TREMENDOUS intrest in them .....   ::)

and i really need to get something into production..

wow

i can say is this universe is far more than any will currently beleave ...

w

from the info i was given and the maps that were drawen ..  there many hidden planets ..  humans do not see.. 

prymids on many ..  as well as a ball  i here there is a hotel that is a temp  shuffel place ...  ;)

huge things are happining out there .. it is best you wake up ..  im almost 100 percent sure the TESLA SHEILD  INDUCES WAKE UP ...  8) :o

All,

I need a peer-review on this circuit.

Improvements, why it will work, why it won't work etc.

Alex.
Alex the Secondary is OPTIONAL and will not charge the Bcap as a Normal JT . Charge come from the C E junction .

for only those that this draws an intrest to ...

i have a message to deliver and a star map ..

 :o

first off this .. is new..  and ill tell you all noone has access to info as such ..  ;)

the events unfolding in the time to come .. will shock you .. im not talking of my inventions and such things....  ::)  that is OLD NEWS..  hence why most of the older crowd are well aware ...  :)

any how  there is a hot planet and a freeze one  im male from freeze and male from hot .. i have rejoined and become ballanced .. there 20 of us ..  the superviser ship is NOW at the FREEZE plannet being repaired .. and ready for round 2 ..  they HAD TO REPAIR IT WITH CRYSTAL..... imagine...

the super vizer is soon scheulded to return to THE RAINBOW CRYSTAL STAR SHIP!   mars is mentioned earth is mentioned the sun is mentiones  the vaccume hole is mentioned ..

you will not beleave ..  any how after repair it is COLLECTING... you will not understand this .. unless your a LIGHTWORKER..   ;)

peace ..

it was said i should post a picture of the map ...
lets just say i will have updates.. as time passes

w814

FIRST DELIVERY WAS FRIDAY ..
next is monday..

10  are brought .. per trip   3 from  sun  3 from freeze 4 from my plannet ..

i posted this here as the FIRST TRIP ...  was some of the ones i work with ...  ;)

anyhow ..

i dont force this on you .. 

lol

you get to live it !  ;D :o :o :o :o

if you dont beleave me that is your choise .. no worries here ... lol

when a 5 and 7 year old deliver this info to yourself..  with the darn explanation i can not argue ...

maybe then you will beleave ....

thank you !

w  this is post #4014 ..... hummmmmm   think that means anything ......  :D 40 14's hummmm

now i can understand how you dont understand as i dont understand yet ..  im aperntly half and half ... so i have been told..... :)

just cuz i dont understand something does not make me close a eye to it ...  if this was the case ...  i guess i would not be a resercher .. 

ill tell ya humans never built the cosmos..  because you would already understand what im teaching ....  lol  ::)

WAKE UP  :o 8)  looks at   69 .....  dont they look like a pair of spirals ..  3  perhaps the 3 feilds produced..   and would it not make sence there 2 pair ...   to a BALLANCED GYROSCOPIC SUBATOMIC PARTICLE ..   kinda like ...   cold + cold - 0  hot + hot - THAT MEANS MIN 6 FEILDS 3 IN OPPSISITE DIRRECTIONS .. and when they smak perhaps an interferience pattern  apears ..

008 = quick sand plannet there many ..... be wize...    mars is showen in the map ... as is earth   

x reps quick sand!

in the star map hand drawn ...  mars is the planet with the 1 in it ...   just look all will spell it out plain as day ...  ;)

All,

I'm sorry to report that the self run board does not work as planned.

Today I did build and test the board. The SCR does switch on at approx.
1,6 volt but they do not switch off again. So when the battery feed back
scr switch on then the current available is big enough to keep the scr on.

Another problem is the forward current Germanium diode. This diode is
direct in line with the input AA battery via the coil. So when the discharge to
load SCR switch on then there is a DC current through that diode and to
the output load that keep the SCR on all the time.

I also tried to use a separate winding on the toroid. But the output from the JT
was above the 8mA SCR switch off current, so the discharge SCR just stayed on.

My conclusion is that this circuit does not work with the JT circuit at all.

Alex.

Alex,

Don't give up yet. I think your on the right path. Sorry to take so long to post this suggestions but........
And it also looks like a lot of unnecessary crap is also going on. I hope things get back to normal soon.
Anyways, would it be possible to incorporate some type of timing circuit with the SCR so that when it turns on, the timer would shut it off after so many seconds. Then, if the battery was still below the threshold it would just turn back on again.

Just a thought.

@MrMag,

Thank you for taking time to help me with this circuit.

Yes, I have also been thinking and have designed a new circuit. In this circuit I use a 5 volt
relay. The relay will turn on when the (two series) bcaps reach 5,1 volt. The zener will open
at 5,1 volt and trigger the SCR. The SCR will switch the double relay. The relay will stay
switched until the voltage over the bcaps has fallen blow the relay holding current. Then the
relay will switch back again. The result will be that the bcaps is discharged into the load
through the hexfet transistor. At the same time another zener will be connected to the bcaps
and back to the AA input battery. This will top up the battery. That is the plan. I have
started to build this circuit.

Alex.

Alex,

I really hope it works!!! Please keep us informed.

It's too bad that things need to get so complicated just to do what seems a simple thing.

Hi Tim,

Yes, but I have tried to avoid using 555 or other current hungry components.
This circuit will not use any power from the bcaps until the relay switches on.
The relay itself uses very little power, only 140mW. I also hope this circuit will
work as planned.

Alex.

Have you looked into this component:

http://www.national.com/mpf/LM/LMC555.html#Overview

Apparently it's exactly the same as a 555 except that it consumes very little power compared to it.

I agree, the 555 is hungry.  Though they make power efficient models, they are extremely small!  Pictured on an inch scale, numbered divisions 1/10th of an inch.

555's use alot of power to charge up the timer cap, and then it just discharges that cap to ground!
It's wasted energy and that i why i never use them in FE circuits.

It's also possible to use a Crystal driven Nanowatt PIC microchip and adjust the frequency through pressing up/down buttons or by simply changing the code,and offcource by (voltage) sensors so it switches when it senses the cap is full.  :)

It's very easy to do, and the last one also protects the cap from overcharging.
