On another thread you mentioned speed?


Regular and extra crispy ( more better)


How to discern? ( or recipe?

So, If Jeg is still interested in the Ruslan Generator,
May I have a suggestion for Jeg.

The schematic below is a bit incomplete.
Can you complete this schematic?

Hi Color
I hope this will work for you.
Enjoikin's circuit has many flaws and mistakes. Using tl494 for HF is a waste of time. Mama company suggests to work with it up to 300Khz. Enjoikin overclocked it but still it is not the optimum way.

In place of TL494 i built a gate oscillator able to go up to 6MHz. By using 1nf for timing capacitor i have a control between 100KHz - 2,5MHz. But If you go to picofarad range then 6MHz is possible. In my board, with no capacitor at all, it reaches a frequency of about 6,5MHz.

First circuit, takes a pulse at the upper left corner, and creates a pulse which is controllable in phase and in width. This pulse goes in to a mixer with the HF oscillations and there you are. You have two outputs here, one normal and one inverted.

Second circuit in addition it uses an extra oscillator which can drive/modulate the HF pulses without any external pulse. This circuit can work as a sync like before, but it can also work as a stand alone burst generator without the need of an external pulse trigger like in the previous circuit. It just needs a small jumper or a switch, to connect the modulator in to the circuit as long as we don't use it for synchronization. So two operations in one board. The drawback in this second circuit is that it outputs an inverted waveform so it also needs an inverted mosfet driver like tc4429. The reason for that is that i used all my available gates and didn't want an extra IC just for one gate. But if you have space for one more IC, then build the double output method like in the previous circuit.

I hope later i will find some time to make a small demo-vid.

Regards
Jeg

I promised, so I will post how the generator works.

Hi If you go through all the Ruslan stuff Russian and Lithuanian publications his device (grenade) is a mathematical equation
meaning the need to stick to that equation or alter the whole device to all mach up using the new values in that same equation.

I don't want to go into that too much here but  he used a push pull out put of each side of 18 Khz thus equaling 36khz total
and wound his grenade with 41.64 Meters of wire.

I can't prove this because I haven't built or experimented with such a build nor do I intend to but there is a man who has
dissected one of his 200 watt devices.

here is a digital replacement of the LM494 circuit of sorts using a 4013 one to produce a 50/50 sqr wave and another to
decide two equal dead time (to reduce zero crossing current and over heating) outputs using 2 CD4093 chips.
the device should be easy to phase lock the katcher and grenade and divide down from a phase lock VFO.

The resister was a 3K3  and the preset a 20k
Te caps were 220pf and a 4700pf

새마을 노래(박정희 작사·작곡)

새벽종이 울렸네 새아침이 밝았네 / 너도 나도 일어나 새마을을 가꾸세
살기 좋은 내마을 우리힘으로 만드세

초가집도 없애고 마을길도 넓히고 푸른동산 만들어 / 알뜰살뜰 다듬세
살기 좋은 내마을 우리힘으로 만드세

서로서로 도와서 땀흘려서 일하고 소득증대 힘써서 / 부자마을 만드세
살기 좋은 내마을 우리힘으로 만드세

우리 모두 굳세게 싸우면서 일하고 일하면서 싸워서 / 새조국을 만드세.
살기 좋은 내마을 우리힘으로 만드세
