BINGO!!!   

200V RINGGINGGGGG PULSES ... 

x6 ill scope it later on today ... 

im impressed...


ist

useing 3904 and the same aaa battery

later has come early 

here are some pictures ..



scope is 50 v /div..

Great work     

Just  wondering  if I understand  this right

It looks to me like your scope shots were taken with the secondarys  not connected to anything .......is this right ?

If so ......  then   you are inducing   current  in the secondarys    then  the  flyback induces  current in  the primary

yes nothing connected to them but i could now wind a collector coil ...

of magnet wire ....  and the ringging fly back could come out like another primary ...

no
?

or i could rectify it as showen and have 6 feeds  but i may add a nano jt to power it with a little more voltage and a button cell ...   but i would reccomend changeing to a 3055 and protect it with a neon ..

ist!

warning!!  be carefull    if i ramped up the voltage ....    it could be a deadly stun gun!!!!

or 1 hell of a spark reactor 

oops i made an ooppeee  lol  my scope is on the 1x not the 10 times

so ya...  lol      its good tho   infact safer ....  lol

ill be back at it later on

peace!

if we increase our driveing voltage the our out will rize keeping the rest the same

im getting 1vdc to 25-30   no if i increased to 30 on the input ...  what will the out put be ?

this is easly done useing a 1 uf cap on the input of this coil  and chargeing it from a nano jt

and a button cell

I am impressed   

do you agree that you are  inducing   flyback   into the  primary ? 


I tried  a simple test    with an  air core  JT then  a   unconnected wire  core  ....... didn;t  notice any difference .........but ......  I didn;t have any real  current flowing ..... so  it probably wasn't  a good test

i can not say for sure at this point!!

but i can power 24 leds with out affecting the rinning pulse on the other coils .... 


hummmmm   i think all coils need to be loaded and then tuned to highest out put ...

i say this cuz my leds were not full brightness

but it did not change the wave on the scope ..

ok so im getting like 20 volts per coil i added 2 togather and my wave grew... up to 30- 35 no diodes

ok now i switched to a 4401 transistor im up to 30v ringinggg  per coil ... 

well i could add full wave rectifiers and some photo flash caps ...  then drain off as i desire 6 out puts of 30 vdc from a aaa sure is ok by me ....

yes.

Is this your primary?
Mine rings too as a primary...

I am finding that if the pickups are all coming from one toroid as this one will be.


I can put a very big load on the whole thing.
But, if I split it into 2 separate outputs, only one of the split parts will do the work.


It can be half and half, but it can be anything. 4 leds will put out 18leds or 18 leds will put out 4 leds.


They take turns. Even though the system can supply enough for all the leds, only one at a time goes on.

UNLESS...unless...
I am finding that by putting a coil of almost any kind, the lights stay on in all the circuits that have the extra coil.
I am working out the details, but a coil hooked up between one wire and the leds, will keep those on

...

warning!!  be carefull  ......ooppeee  lol  my scope is on the 1x not the 10 times

I have had to add a 33ohm resistor at the battery because the leds were hurting my eyes. The 33 ohm brought the light to almost out. I can see if something makes them change, but they are safe for me. (also safe for the leds, at one point I was blowing them too)

they are very bright with the primary at resonance.
...

if we increase our driving voltage the out put will rise keeping the rest the same
..
this is easily done using a 1 uf cap on the input of this coil  and charging it from a nano jt

and a button cell

Ist, if you put a small value resistor in series with the pos side of the battery, you can easily see the effect of changing the driving voltage without blowing more leds. (!)

Good stuff ist
thank you,
