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 !

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 ......  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    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,

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.
