Do not be discouraged Eng I think you are on track.

For cheap parts look at the capacitors and HV diode of old oven microwave, they are good alternatives in series and in parallel. Available and very high voltage.

regards spark2

ive had nothing but bad luck with microwave oven caps, internal resistors

i see it as u have wrongly connected ur spark gap and capacitor. connect as Don bertonee way but not Tesla Way as u have Diode in built in ur Flyback.

SEE IMAGE BELOW

I see U HAVE LATEST FLYBACK WITH INBUILT DIODE CONNECT ACCORDINGLY AS SHOWN IN FIGURE.

ITS BEST TO CONNECT THE FLYBACK WITH DON WAY AS SHOWN IN BERTONEE CIRCUIT BELOW. JUST REMEMBER
THE SPARK IS BETWEEN GROUND PIN AND LC CAP COMBINATION.
U CAN USE OTHER METHOD ALSO BELOW BERTONEE FIG. WHERE HT OF FLYBACK IS CONNECTED TO CAP THEN SPARKED TO COIL.

HOPE U GET IT WOT I MEANT IF NOT SHOOT UR QUERY.

I think I've tried that setup with SG in series and did not work. But to be sure I try it again.
Today I hooked secondary with diodes as Avplug to MO cap and it was charging
Thanks

maintaining resonance

Zilano would You please be so kind...

Will you give an example of how the calculation goes for maintaining resonance between primary and secondary when the natural frequency is used.
What is the natural frequency of the 12 m long wire and what of the 3 m /2x1.5 m/ long wire / this is a step down type /
I gave this parameters, if it is not god use another.


L1 parameter: L2 parameter:

12 m long 2x1.5m long
1 mm diameter wire 3 mm diameter wire
77 turns 7+7 turns
43 mm diameter of the coil former 50 mm diameter of the coil former



L1 for example measured with LCR meter gives the value 70uH and 3 pF
L2 for example measured gives 2 uH with 2.5 pF each of the two coil or let say 4 uH and 5 pF when joined

The output of the HV module /flyback transformer/ is 2000V and 25KHz


Here is a schematic :



first of all we are seeking for C1

Don't want You to feel under pressure but it will help a lot

wound using lamda/4 and 4 lamda with weights of primary= secondary

wound the primary on plastic tube that is slideable inside the secondary which is wound on the plastic tube.

now take primary coil wound on plastic tube attach LCR meter and note down L and C

do same for secondary but not with primary inside secondary and note L and C with LCR meter and use frequency calculator to find natural resonant frequency of ur coils.

LC Resonance Frequency Calculator at WhatCircuits.com

if u follow rule lamda/4 and 4 lamda then frequency will be approximately same for L primary and L secondary. and if there comes difference
it can be adjusted by sliding primary inside secondary.

remember

to calculate lamda length for full wave half wave and quarter wave

use this

Online Conversion - Frequency Wavelength Calculator

hope this helps

ps: since u r using coil natural capacitance and external capacitor also so the frequency is changed from natural frequency. so if u use cap + coil combination then u have C= C of coil(parasitic capacitance)+ C of cap.

natural frequency works when u dont attach any caps to coil and just work with L and parasitic capacitance of coil C( capacitance that happens naturally happen to be between turns of coil.)


refer my older deleted posts and u will learn more. and read Don document and 246 thing.

thief circuit

hi all
today i test a half of thief circuit
it is work as you see in pic

series spark gap?

@zilano:

didnt u once say serial spark gap wont give overunity? Cause in ur newest drawings u have it serial?
Or I misunderstood u there?
Or parallel spark is only for conversion from cold to hot after charge cap?

Kind regards

yes only for cold to hot conversion. just follow the don bertonee way of connecting primary then u will have less problems in secondary side.

if u can get ferrite rings say 10 ferrite rings of same diameter as thief circuit uses ferrite ring core. u will have overunity in ur circuit. the dotted lines u see r ferrite core rings in thief circuit
experiment n explore u r right on track. Good luck and best wishes.

hi zilano

i have but not same size .
i rewinding my device according to rules of length
but step down not as don smith step up is same rules
my cables length is 16 m and 4 m

different ferite rings

stick em togather and use them. listen solve step down later try to get overunity first. if u have less power fed than output its the best thing. step down can be done later in stage of plauson convertor. just experiment how to get more amps of the circuit using plauson.

more bright and hot bulbs means more amps out.

HINT: THERE IS A RESONANCE RELATION BETWEEN HV SPARK CIRCUIT AND THE LOCAL OSCILLATOR OF THE TWO TRANSISTOR CIRCUIT IN THIEF CIRCUIT. IF U CATCH THAT U WILL HAVE OVER UNITY.

Today I've did this and works well. I did a vid to the toroid and bulb which ends in an arcing on my toroid
Don Smith primary driver to toroid - YouTube
My secondary is charging the MO caps as I've said before with the avramenko diodes to an SG.
I've tried to light the bulb on the secondary SG but invain maybe I need more HV caps.
Thanks.

ok i will work on step up now
concern to thief circuit what value of capacitors and what do the second half of circuit?
