Color Junior

Jeg, like my dad, is like a teacher with outstanding talent in various fields.
I really thank you but the real talent is your father who made all this progress without gear! Its like the mission impossible movie  :)

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

The man for this is AG! But i anyway need a sync board and so i will try your circuit the next days i hope.

Best regards

Jeg :

It is true that AG has created this forum,
I and AG are a relationship between someone who knows nothing.

Below is a picture of my shades.
This is a clear picture of me. ;D ;D 8) 8)

Since we have summoned all the schematics from the Russian site above, there will be a lot of useful information for Jeg.
It's not about making Tesla run at Mhz from scratch.
It is a technology that is amplified (synchronized) tenfold at about 16Khz, so you only need to operate Tesla in the range of 16Khz to 200Khz.
And listen to the members of the bear (zlatko2013).
The one who provided all the schematics by a member of Gom (zlatko2013).

https://www.youtube.com/watch?v=LGvNv2EXKkU
https://www.youtube.com/watch?v=BPjzpL24Y5A

And reject the words of members who are wary of bear members.
In particular, ignore the words of the member "nnaill".
I too have experience of failing experiments because I was tricked by "nnaill". ;D ;D 8) 8)

Please be patient with enjoykin4 circuit, do not trust.
This is a circuit diagram that deceives members by using discontinued parts to make Mhz that does not work. ;D ;D ::) ::)
For enjoykin4 circuit, refer only to the part that the Gom member says. 8)

zlatko2013 :

добавлю от себя - на поиски информации которая указана выше ушло 3 месяца. Были и другие схемные решения - которые были собраны но не подошли. Потрачено примерно 15000 руб. Так что это не дешевое удовольствие. Думаю что информация выше съэкономит и время и деньги - на сбор этой установке...
А вообще это все лишь для того чтоб в конце концов проверить - есть ли эффект CE или нет. Так давайте же зажгем 4 КВатта!!!

I will add from myself - it took 3 months to find the information that is indicated above. There were other circuit solutions - which were assembled but did not fit. Spent about 15,000 rubles. So this is not a cheap treat. I think that the information above will save both time and money - on collecting this installation ...
In general, this is all just in order to finally check whether there is a CE effect or not. So let's fire up 4 kW!!!

Why bother with an LM494 you know it's not going to work at 2Mhz , when is all you need is a CD4093 and to create the dead time from a CD4046 VFO
and simply divide it down for demodulation.

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

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

1) The 4,7nF capacitor goes to pin13 and not to pin8 as you have made it above.
2)The IC we want is the 74LS132 schmitt quad nand gates. Without the letter "D" at the end which i think is the smd type of the IC.
3) In your drawing you forgot two more gates so you need one more IC for them. In total you will need 3XIC's in a total of 10Xgates. Look the original circuit again above.
4) When you finish your board you need to attach 100nF ceramic capacitors straight on pins 7,14 of all your three IC's
5) I am afraid that you will need an oscilloscope to adjust and learn the behaviour of the board.

That is the associated video which will give you an idea of the layout.

The business of modifying/upgrading old ready-made items to new ones is one of the most thriving businesses around the world.

This is a good example of how a promissing thread got totally diverted in to the ground. Yes. The agents live amongst us.

Mr Plasterer  Perhaps Jed has a ware house full of old Low Power TTL devices  ;D ;D

At some stage Ruslan bless him  :o let the cat out of the bag in the Russian language
when he started selling his devices some where on this tread the young lady on this
thread posted a link to it not all that long ago but it's such a mess god knows where
it is now, but its still on here only find it and go through it all.

There is this posting some years ago that works as far as generating the timing
pulses is concerned. I knocked up the first 2 stages on a bread board the delay
and the pulse width section and fed it with a CD4047 oscillator and used a CD4093
at 15 volts and it worked well after a bit of experimentation but ran out of components
after that  8) :-\ :-\

Regarding Color's 494 circuit I couldn't get the 494 to lock on the correct place  and
it kept trying to lock while having some kind of unstable  'twitch' where the data window
appeared to try a synchronous lock, It was just a wast of time. Any way such is life.

Yes too sloppy here
And a bit vague on what is being said


I think a new fresh separate topic at all forums will be good !


For teaching purposes ( educational tutorials on how to save our planet


Also we have “open source” experimenters in need of equipment ( India and other places)
And probably funds too or at least parts





Not just one mans opinion
