I decided to start this thread and to dedicate it just to Mr Brovin and to experiments with his device(s).

I was playing today a bit with the Kacher. I just putted three coils on ferrite bar. All three coils same length and as om the picture below.
One side coil forms a feedback and he other end coil forms LC tank circuit.  My input was around 2.6V @ 0.4A.  Normally I am getting dumping wave form. But when approached the other ferite rod right next to this set up, the wave form changed in to the growing shape. 
Not sure If I can do something with hat, more to experiment. Just wanted to share some findings.

(sorry to mix this with grenade instead of just kacher :/ )
I have a set of like 12 coils that are all about the same inuctance... should be able to get them all near resonance...



I blew up another 3 transistors :(
I have a 2n3055.  I am able (now) to get 1.43Mhz resonance on other coils also...


Today (during the day) when I tried to get it to work the same way to allow the high resonance; it would drop into a 35Khz output; that looked like a square wave on the grenade... well it was definately a square wave on the collector and base *boggle* high resistance... I dunno if I've partially blown this transistor which is why it was where it was...


avoid discharging the output cap on the grenade rapidly; this can result in a back-spike to the kacher if direct coupled.... that's how I've blown up most of them... I feel a 5V zener on the base is a good thing to add... seems transistors lasted longer as long as I had that... it doesn't have to be big if you're at low power... but rarely does my base really go above 4V; unless driving with a high input voltage (27+V) and this also protects it from under voltage; several transistors go negative on the base  (not really sure if this capacitance should maybe be increased, and keep the negative dip?  Where does it go? Does it get wasted?  Seems input power goes down when the negative dip isn't there... recovery into low side is better?)


Is it allowed to call a kacher an exciter from time to time?  GBLuer exciter is exactly the same; except the transistor chosen and the resistances used...


http://overunity.com/8977/gbluerslayer-exiter/msg257355/#msg257355


http://www.instructables.com/id/How-to-Build-a-Slayer-Exciter/  (this has just a diode; a zener would protect overvoltage)  (I guess maybe could use a couple LEDs instead)


Google image search; gbluer exciter


*sorry I'm already expecting a no; when really the only choice is 'of course' so go ahead and say no and I'll not mention it again * :)
----
Yay that saved to post :)  database was crashed earlier...
*sigh* nothing working again...


Also think that pancake style coils would work well as primary/secondary variation... mine weren't secured well and have come apart :/

I also use 3055 tranzistors and also blew several of them yesterday :)  Some sound from my coil gradually increasing and- gone :)

As I have my Kacher on the ferite rod, I wondender how big role plays here the magnetic propagation delay.  There is some study made by Steorn - the Irish company who publicly presented some OU device several years back and than they got quiet :) 
Some of their finding in the pfd enclosed.

I found that shifting the primary on the secondary can dramatically improve output; such that there is a exact match in frequencies. 
I've moved my ground a few times; and maybe that's what the issue is now... it was working good :(  now it's all high current and no output....


this one part tests correctly; but it's like the internals are broken so that almost any gate voltage more than zero opens it.... (maybe it's the ground; sometimes it's just that I need to tell someone what I was doing)


I have these 3 coils that all oscillate together so I can light a flouresent at each one, but not between with only a ground connecion; was going to dig up that current transformer thing and try it between the coil and ground and see... oh and to connect top to top? and the second side is open?

Nice thread John,

i wanted to do some experiments with 2 Kacher coils driven by 1 primary for some time and i guess this thread is right for this.

In the back of my mind the following website and the below diagram plays a role allthough i am aware its very different.

http://www.bibliotecapleyades.net/tesla/esp_tesla_20.htm

Both kachers are running kind of, and there is some interaction as the streamers are mingling.

Need to set up the glas inbetween with a fixture so its more stable, and also a conductive groundplain underneath the 2 coils could improve the interaction.

Anyway, here the first video: https://www.youtube.com/watch?v=8xAmeFA-L2U&feature=youtu.be

Hi Itsu, some fine experiment you running. No fire balls yet ;) ? What about to try top capacitors with the charge breaker? I woud wrap the bulbs in kitchen foil and a piece of wire. Looking forward to see more on your chanel.

Regarding having one primary for two secondaries, you may also be interested in this guy's videos.
He is not using tesla coils, but self wound transformers (his last video uses an air core  transformer) but
his approach should be applicable for use with kacher driver circuits. I believe he is testing with both phase
opposing secondaries, and also with phase opposing primary windings. He calls his transformer a 'free energy' transformer,
but he actually doesn't have the equipment to do proper power measurements. What his videos show
is that adding a light bulb load does not increase the input current to the primary. That doesn't say anything about
over unity of course, but it is still interesting. He doesn't have a scope to look at the phase relationship between the
primary voltage and the primary current, and I would guess that when he connects the light bulb load that the
input phase is shifting, increasing the input real power consumption. A person would need a scope to confirm. Anyway, this approach
could probably be adapted to a kacher-brovina driver. Read the description section for his videos. He has English descriptions of what
he is doing in the videos.

Nice :) Unfortunatly I noticed the article was talking about MegaVolts... so he's already expecting to start with a HV supply with a spark gap instead...


but those are quite lively ends on your coils

Hi itsu,

This experiment of yours have given me ideas for suggestion.
The result would be similar my simplified version in my head.
Assembled just 1 tall tesla coil but primary coil is in the middle.
Both ends of tesla coil is connected to mini sphere place quite near to each other at the top.But one side of tesla coil there is ferrite rod placed in it to intentionally reduce it's resonance frequency which was similar as another half of tesla coil.

Example both half resonance was at 300khz.But after placing ferrite another half can be made to resonate 1/2 of it's original frequency.

Nano or microsecond pulse eg:via spark gap is still the key to unlock this tiny fireball.
I noticed spark can go through thick sheet of glass as also seen in your video.Isn't this wonderful surprise.

Hello Itsu,

The respecitve document by William Lyne deals with creating ball-lightnings and not mutual discharge between the hot terminals of both coils.

the two coil are too close. One can see that the big coil discharges into the small one. The stronger em-field of the big coil chokes the small coil so the small coil can not work properly

It would be necessary to experiment with variation of  the distance between the two coils and variation of the primary so that
for example you have two primaries put in parallel or in series with each other.
Also small spheres are necessary at the hot side but what size ?

Calculation of the capacitance of a sphere against space or ground:

C = C = 4 pi εo ε r

permittivity of vacuum = εo = 8.854187 10 exp-12 As/Vm

http://de.wikipedia.org/wiki/Permittivität

relative permittivity of air : 1.00053

example of a sphere with radius r = 0,05 m ( 10 cm diameter)

C = 12.566 * 8.854187 10 exp-12 As/Vm * 1.00053 * 0.05 m = 5.566 10 exp-12 As/V = 5.566 pF


You have entered a very complex work.

Regards

Kator01

Thanks for your comments and suggestions guys.

i am aware its very different from the linked document, but like mentioned by d3x0r, the used potential there (Megavolts) will be impossible to create by me.

I just wanted to see what is going to happen and perhaps put some idea's in someones head.

I guess i have to make some spheres (10/15cm diameter) to put ontop.

For now i put the glass plate in a fixture and was able to tune with my hand either the big or small coil to produce a stronger streamer which seems to happen when the small coil is exactly double the frequency (1120KHz) of the big coil (560KHz), but i need to verify that by additional measurements somehow.

Kacher Delamorto,
https://www.youtube.com/watch?v=3ZN1zFzgQkk  Shame he doesn't give us exact values IN/OUT.  I think I'll give it a try over weekend.

Also I have some document about Brovin kacher. It is in Russian. I will make a translation in my free time. Quite interesting text.

Still fooling around with the dual kacher, now fitted with a topload and put on a groundplane.
Primaries are in series from 1 driver.

With a tuning aid, i can tune the smaller kacher into the double frequency of the bigger one and kind of lock both

I have no more streamers, even with 24V @ 4A, but the transistor heats up rapidly then.
