As we have some people interested in this device.. and dave suggested a new thread for it, so here it is!!

seth and dlbarre... lets start the build!



Here it is my replica:

Input: 20V at arround 1.2A (24W) at best, im lightning 240V (15W) fridge's incandescent bulbs wirelessly at small distance, by the time of the video i was with somekind of problem and my performance was decreasing i was not able to find why, but in the first tests, before i made it, i was even able to light a 25W incandescent bulb and the 15W bulbs much more brighter!

This one goes to cosmir farmer, seth, dllabarre, luno, baroutologos, wings, abcstore, kdas, bolt!

Enjoy! YouTube - jujusalva's Channel

Hi Guys!

Lets pool our knowledge of this thingy. It seems to have many variations in design, so i suggest we get an idea of what constitutes a basic ''kacher'' or ''brovin generator''.

Both the schematics above mention 50/50/50 for the turns on the coils. Have you already tried either schematic Tantric? In the video i can see at least 4 coils, and on various air core pipes and one a flat pancake coil....this only confuses me more - perhaps just another variation on the initial design?

Perhaps someone here has a good idea of a basic Kacher design? Luno?? you seem to know the russian forums well.

When you all decide on a schematic, please translate the parts you're going to use so I can start.

Also translate any important build instructions if this isn't asking too much.

Thank you,

if the schematic is that one of your last post, that is a basic TC or Wireless Exiter!

i think the The brovin schematics from the video are the ones in my first post! that clearly mention 2 output coils, connected in different sides of the circuit, can you translate the text that is in those schematics images to english please?

thank youuuu

Hello @ All,

I have said it to OU.com forum, i will post also here.
Kacher is a very useful tool for studying HF electricity in all its glory. Contrary to any shocked-pulse Tesla coil (cap-discharge) that creates a "spiky" resoannce, Kacher will produce a very smooth one.

You can:
-light light bulbs and study one wire electricity transfer
-light FL tubes at a distance or connected to them
- see the "Gray phenomenon" of lighting a bulb submerged in tap water at full brightness (as Hair pin circuit)

...and many other things.

...

I have build some of them propose by Destine, (diagram few posts above)
What i see in luno's post and can be of value for tuning the Kacher is tha home-made variable capacitor between transistor base and coil.

I will surely give it a go.

@ABC Thanks for the simple schematic!!! what are the number of turns on each inductor?

@Tantric - thanks for the simple explanation on your private message - you da man!

Hi guys,

I have read something about Brovin's kacher on one of the most popular alternative energy Russian sites - www.skif.biz - Àëüòåðíàòèâíàÿ ýíåðãèÿ (...è èíûå àëüòåðíàòèâû).

As I understand it is a type of self-tuning Tesla coil.

The pri and the sec are not connected hardly by inductance. The sec gets radiant pulse from the pri and shuts off the transistor.

Regards,
kdas

Primary - 3-5 turns of heavy gauge wire, I use D~8mm
Secondary - the more the better

If it doesn't work, change polarity on the primary

Sounds simple enough!!!! Thanks ever so much for your help....i might go to the market tomorrow and get that transistor......do you know of any others which will probably work??
I can use the inductors i already have in my tesla coil and kapagen. lovely!


Ive got a printer here which has stopped working and is waiting for destruction, and recycling of components....probably a few transistors in there, eh? anyone know if they'd be up for this??? I'll try them anyway

hi,

that circuit will work with very range of PNP that is rated to the voltage and current that you will be putting in the system...

you can also use an NPN transistor like TIP3055, TIP31C, but that ones are rated to 100V i think... to use the NPN circuit, just invert the colector and emiter and put: emiter to battery negative, and colector to primary and end primary to battery positive!

my first taught is this was a new concept, but is the same concept of what the guys call as "Wireless Exiter"... the circuit is identical, but maybe this katcher is used with much more power?


Hi ABC, how much power are you putting in your KATCHER?

hugs

About 10-20W (18v, .5-1A)

Any power transistor will work just fine... Just don't get shocked by the scope shots

Hi guys

Ive spent the day trying to build the simple looking Katcher from ABC's post 14.

On this diagram, is L2 the secondary, and L1 the primary??? I assumed the opposite....i thought the output coil would be the one with as many turns as possible.

Havent had any success yet, but my resistor and transistor are getting very very hot. Im using an IRF630 (i think this is a MOSFET..but i aint sure....). Found it inside an old monitor.

any ideas where im going wrong?

NB Im using 6V/12V batteries, therefore no smoothing capacitors in my circuit. Just 2 coils and a mosfet and a resistor.

__________________
 

yeap my friend, the big coil (many turns) is the output coil! at the loose end of it you will see plasma!

you have to try all possible configurations, try to change the primary sides connected to the circuit... just swap them! if you dont have sucess, try also to change the side of the secondary that is connected to the base!

and dont forget the primary should be positioned near the wire end connected to transistor "base"!

if dont work, change the primary sides again! you will get ther!

hugs

EDIT: yes IRF is a mosphet, but try to download datasheet and see if it is "pnp" setup and you are connecting the correct pins to correct sides!

As I have read it is necessary to touch the base by screwdriver to start the process in some cases. And I am not sure that mosfet can help here. I have only seen bipolar transistors in this circuit.

__________________
 

This mosfet is switching type, your need a mosfet driver to close it, or will be still open and wil get very hot, and of course will not oscilate, get some clasis bipolar tranzistor if you want some sucess, in best way, some of ampflier classes. Some which be able to work on desired frequency (rez f of the secondary)

__________________
 

Cheers for the advice all of you!!!

I really appreciate it - all my builds are a group effort

I'll try and get a variety of classic bipolar transistors. In the end i destroyed my mosfets by trying to wire them up to a flyback transformer - they dont seem to work well for HV power source either.

Still, lots of fun like always!

Use a TV line o/p transistor they are usually rated around 1700 volts and handle about 70 watts. Make sure its on a good heatsink and it should work very well off a 12 volt battery.

It will blow your socks off!

hi bolt

how do i indentify wich one is the TV line o/p transistor?

i have to old tv's damaged in my garage...

@Juju

Sorry I've been away for the past week.

I'm trying to catch up with the Katcher.

Is this the schematic you all decided to use:

If so, what are the parts values you decided on?

Transformer?

Thanks,

Are you sure your wire is ~ 8mm diameter?
Thats huge according to this chart or this chart is wrong.
Regular, solid, 20 amp house wire in US is 2mm.

AWG to square mm Wire Gauge Conversion

Please clarify.

my friend, there's no need for the transformer!

you can feed the circuit from a 12v battery or wall adaptor...

he is right about the wire gauge, but you can use 5 mm wire, or even 1mm will also work...

in the video that i posted up in the thread you can see that the guy use very thick wire, close to 8mm or so!

from what i understand, the katcher circuit is just what we called the "slayer exiter"!

you can see the video of my katcher here: YouTube - jujusalva's Channel

Thank you,

Can you send me the schematic you used (translated to english) and the parts you used?

What size wire and how many turns for each coil?

I want to stop at the electronic store on my way home today to buy parts.

Thank you,

Hi guys!

Im buying some...

TIP3055
TIP42C

and..
MJE13009

I chose the first 2 as i found people on here using them for exiters and kachers. As i understand it (and its partly thanks to you juju) a kacher/brovin generator is pretty similar to a exiter/SEC or even a Tesla coil. I already have a Tesla coil, but it has been an ambition of mine to make a ''mini tesla coil'', as well as a big ''sh*t your pant'' tesla coil .


I chose the last one due to this website

Transistor Driven High Voltage Flyback Transformer Page.

where the tranny seems to work very well in a circuit with a flyback transformer. (wish i could find a CHEAP NTE 284 also.... : )....i dont see much difference between the circuit on the link above, and the kacher/exiter/mini tesla coil. Maybe im wrong?

Anyway - i need at least a 20 quid order from the shop im buying from.....so ANY OTHER TRANSISTORS RECOMMENDED FOR EXITERS/SECS/KACHERS/BROVIN GENNYS/SOLID STATE TESLA COILS????

All will be ordered and arrive in a week or two!

sory, just seen your post now, am i still on time?

my secondary is 0.3mm wire... 150ohm

the primary is 1mm wire, 5 turns (but you can use more thicker!

the schematic is that one in your post (PNP), but instead i use NPN config, i suggest TIP3055 or TIP31C... the secondary is connected to the base (on the side closer to primary), the primary is connected from batery positive to colector, and emiter goes to batery negative! if dont work, change the primary end wires!

to make it self start put a transistor of 1k to 5k from bat positive to base!
