@ resonanceman

Very interesting. Thanks.

I hope you will post more of your tests with them.

Attached is my test fixture for testing my replication of K1zm toroid circuit for lighting filament bulbs. My capacitor is only half of his capacitance so it should charge up 4 times quicker to a given voltage and hold 1/4 the energy when at the same voltage. The neons are a safety feature to limit the capacitor voltage to 240 volts so it will not blow up.

The capacitor will charge to 140 volts in about 10 seconds. At this voltage there is enough energy stored to flash the 7 watt bulb to about the same brightness as in his video.

I was unable to get 2N2222 transistors to work well with the turns on my toroid. But, the MPSA06 transistors seem to producing about the same power.

i have a question

who can and will answer?

if i have 4 caps ... and 4 realays  like so and

if i had a jt in front of it


    J     1      1       2     2      3      3      4     4
    T    cap relay cap realy cap relay cap relay

THEN I COULD GO -------- = FILL CYCLE  ________ = DRAIN CYCLE
           ----------------------------------------
    J     1      1       2     2      3      3      4     4
    T    cap relay cap realy cap relay cap relay
                  _________________
           
OR YOU COULD GO .. 

    J     1      1       2     2      3      3      4     4     =   120V VIBRATING 
    T    cap relay cap realy cap relay cap relay  =    RELAY

just some ideas ..

as the cap 1 charges to the relay value it closes and begins to charge cap 2 then relay 2 closes ... and so on .. if you increased the voltage of the relays and cap values along the way .. you could probally acheive any desire you wanted ..  you can then chase it with a drain cycle ..  that would take good timeing ..

in the last text art   you see a vibratting relay that has a high voltage supply and what ever value cap you wish to discharge ..  it is powered from the cap cascade you could use it to do many things

agin just some ideas

W

hint ...  if you have the MONEY .... i guess you could do this with boost caps .......   fill  and drain at 12vdc via invertor ... 

or build a few power supply coils ...  and run RIGHT THROUGH  high amp ..... 

: ) ; ) 

it must be christmas year round round here ...

xee2
you once said that a friend sent you some xenon flash tubes..
well i had a friend send me some 1uf 630v caps and three of them in a series with one on those flash tubes for a spark gap instead of using a scr or triac.. does some very , very interesting stuff..
i hope you know what i mean..
i think the doped conductors in the tubes are causing a boost in output.. .. ..

@ kooler

I like investigating new discoveries. Thanks.
