Ok, here are example calculations. I might made some mistakes based on understanding and will adjust it in an process if needed:

The base pipe diameter is 50mm and the length is 20 cm
Calclutated wire lengths (2piR*length / wire diameter (skipped at the moment)) according to http://www.1728.org/freqwave.htm
31415.926535897932384626433832795 mm - layer 1+2

7853.9816339744830961566084581988 mm - layer 5+6
=
1/4 wave 54977.871437821381673096259207392 mm - 5.453MHz - main grenade coil
full wave 219911.48575128552669238503682957 mm - 1.3632MHz

1/3 wave = 73303.828583761842230795012276522 mm - 4.0897MHz - tesla coil 1/4
Tesla full wave 293215.31433504736892318004910609 mm = 1.0224MHz

Inductor 1/2 wave = 109955.74287564276334619251841479 mm 2.7265MHz
Inductor 100th harmonics = 10995574.287564276334619251841479 mm 27.265kHz

P.S> Ruslan used wire of 2.5mm^2 (diameter 0.8mm) so you can practice and adjust this Also we have 2 layers not 1, so you need multiply length by 2

Cheers!

Thanks T1000.

My 2.5mm^2 is around 3.6mm diameter. The Tesla coil wire is 0.8mm.

If we multiply by 2 we get 146.6m (T coil) and 109.94m (grenade coil), which seems far too long, as does 73.3m and 54.97m!

Nope, he just was talking only about tube diameter, width, wavelength and frequency.

Hi T-1000. Ok, thanks. Where are you getting the stuff about the 1/3 wavelength from?
Akula talked about that in one of his videos, but Ruslan said he is tuning his tesla coil to run around
2 MHz, which is the full wavelength frequency for a grenade coil wire length of 37.5m, taking 37.5m as a quarter wavelength.
37.5 x 4 = 150m, which corresponds to a frequency of 2 MHz, ignoring the small difference the velocity factor
of wire makes.
All the best...

When Ruslan was explaining he stated this 1/3 wavelength so I am calculating according to his explanations.
Also we are typically speaking about 1/4th resonance but the truth will reveal as soon as all frequencies match between themselves.
And the grenade coil is standing wave receiver which add unknowns to standard radio receiver calculations so will see about it.

I haven't tried it yet, but using a tesla coil calculator app (JavaTC), a wire length of
37.5m should work out to about approx. 120 turns on a 50mm OD coil form, and should have
a resonance at around 2.827 MHz. That should be a winding length of about 20cm.
This is calculated using 18AWG magnet wire (0.82mm^2). This allows for a little spacing
between each turn to take into account the magnet wire varnish insulation. This is also assuming
I didn't make an error when using JavaTC.

Since tesla coils (as any coil) can have more than one resonance point, I am not sure if a kacher
driver would operate at that resonance point or another resonance point. I hope to find time to try
this, this coming weekend.

You can probably get it to resonate at a bit higher frequency if you use some spacing between
each winding. Once you add the top loading 'antenna' coil, this resonant frequency will likely
drop, so you may well need to start removing some windings from the secondary from there to tune.
All the best...

Thanks Void. I will shortly be at this point myself, so should be able to report my findings. I think the spacing will be important.

Hi Hoppy. The calculated numbers I got from that program javaTC seem a little strange to me,
so I will wind my tesla coil secondary within the next little while to see what is up. I am going to use
40m of 18AWG as a starting point and see where that gets me. Seems like the coil winding length should
be longer than 20cm for 37.5m of wire.

I'll see how it works out and report back.
All the best...

The diodes and choke in the green box makes the now dc voltage across the bulb go negative compared to ground, right?
At least it does with me, so ground becomes the more (60V dc in my case) positive side.

Hi Hoppy. It looks looks those numbers I got from javaTC were off.
I wound 40m of 18AWG magnet wire on a 50mm OD pipe (tight wound)
and the winding length came out to about 28cm. If that number was off then
the calculated resonant frequency for 37.5m may well be off as well. Probably have
to reduce the number of turns a fair bit, but we'll see.
Once I test with a kacher driver I will post back the resonant frequency, but I
will probably shorten to 37.5m wire length first to see what the kacher operating frequency
is for that length.
All the best...

Hi Void,

Thanks for your preliminary report.

I've just finished testing my first Kacher secondary wind. I have 26m wound on 50mm pipe for a length of 170mm. Natural resonance using a six turn primary is coming out at 1.6Mhz, injected from SG. My wire is 0.9mm diameter and adjacent turns are not tightly closed-up. I have tried to space the windings slightly.

Hi Hoppy. Ok, interesting on the natural resonant frequency being at 1.6 MHz.
I imagine it will run at a fair bit higher frequency with the kacher driver in place
for a 26m wire length.
Added: JavaTC puts your resonant frequency at about 3.9 MHz.

Just for the halibut, I hooked up a breadboarded 2SC5200 kacher driver to my 40m wire
length tesla coil, with about 4 turns primary close wound on the bottom of the secondary.
With the power supply set to 12VDC, I am getting a sinewave at 2.5MHz. That is with
40m wire length, so the javaTC program seems to have been pretty close at estimating 2.83MHz
resonance for 37.5m wire length. If I shorten my wire length down to 37.5m and space the windings a bit,
I should get close to 3 MHz I would guess. I was getting a few mm's arcing to a screwdriver tip held
up to the wire end at the top of the secondary winding. This makes the bench power supply go spastic,
so it is risky with a bench power supply.

I have a 5KP10CALFCT-ND TVS diode (clamps at 17V max) from
the base to ground for overvoltage protection. I also had the chassis ground on the kacher circuit grounded to earth ground.

The kacher driver circuit was only drawing about 160mA at 12VDC with this arrangement.

Here's a scope shot.
Yellow trace is a probe placed a few inches away from the secondary winding.
Blue trace is the transistor base signal. Base signal looks pretty funky.

All the best...

Void · « **Reply #5951 on:** October 22, 2014, 01:59:07 AM »

P.S. I hooked up a large sheet of aluminium foil to the end of the kacher
secondary with an alligator clip lead to simulate connecting a big antenna coil on the end, and the
frequency dropped to 1.4 MHz. That's a 44% drop in frequency. Using that as a rough guideline,
it would appear that we should need a non top loaded frequency of roughly 3.6 MHz at least to still
hold to about 2 MHz once the large antenna coil is connected.
All the best...

hi guys,

I have just completed designing my Tesla coil to Yoke driver stage with duty cycle control which will be perfectly in sync with the Tesla coil at 1/60 the frequency of Tesla coil.

Long story short

-By placing 1 short wire <10cm which serve as Antenna couple of cm away from tesla coil with 2 protection diode 1N4148 across 74HC4017 supply rail from the Clk input.
Assume my Tesla coil is running at 1.60 Mhz it is automatically divided by 60 .Result would be =1600000/60 = 26666.666Hz or 26.666Khz.
This output frequency(Channel A in virtual scope ) is phase into 2 half positive and negative half and i have also implemented duty cycle control which is currently set to around 40% duty at the moment(cater for the dead time easily).

Using the above automatic frequency technique .To quickly down tune the tesla coil say from high frequency 2.xxMhz to whatever lower frequency.I merely would have to slowly insert ferrite into tesla coil and the yoke driver output would be in sync with tesla coil higher or lower frequency.

The only thing i have not confirmed if i need to create phase shifting stage like it was done for the nanosecond generator circuit version 7.0 which i have previously upload so that nano pulse appear middle.
This is to ensure that negative peak eg:1.6Mhz from tesla coil would be aligned with positive peak of sinewave eg:26.666khz at 1/60th frequency of tesla coil."Remember 60th Sub-Harmonics"

I will upload a youtube video later in the day provided if there sufficient time to demonstrate this simple but highly effective Automatic frequency control circuit with tesla coil placed near by.

I have this attached this untested version since phase shifting is not tested yet or if need to implement for the first stage.
----------------------------------
The only thing at this moment which there is no shortcut is the capacitor value selection eg:0.47uf or 0.47uf x 2 from yoke to 25 turns.I do not have a yoke or large nano crystalline toroid yet.

Please note in one the Ruslan video there is smaller value capacitor which was connected in parallel with 0.47uf capacitor.This is obviously used for fine tuning purpose.

------------------------------
Alot of "Mental" planning is needed before implementation.Primary objective to save time "Physically" in the end.

---------------------------------------------
Latest update-Look what i have just got from the postman on a local holiday today.
Large Nano-crystalline toroid from www.cwsbytemark.com as backup to the 2 different USSR Yoke core which is on the way.

Right.

Thanks, so we have to be carefull when using electrolytic capacitors there.
Guess it does not matter when using a PSU, it will work either way.
