Kacher Brovina from a 220 volt network

Brovin's kacher is a demonstration invention, very similar to a Tesla coil, but made according to a completely different design.

The kacher generates a voltage of about 1000 thousand volts, can light fluorescent lamps and gases in flasks, it also produces sparks and you can play with them, since the voltage frequency reaches 250 Hertz and the current passes through human skin.

Details

To make the device we need a few parts, namely:

• 1. Choke for fluorescent lamps or mains winding of a transformer. (preferably 100 watt)
• 2. Diode. (I took 31DQ104L, preferably more than 2 amps, with a margin)
• 3. Ceramic or film capacitor marked 105 (1 µF) at 400 volts.
• 4. Two 50 kOhm resistors. and 10 kOhm. (variable resistors can be used)
• 5. Two zener diodes.
• 6.1. Field effect transistor, suitable for IRF740, IRFP460 and many others. (maximum voltage 350 V)
• 6.2. A bipolar transistor (if there is no field-effect transistor) is ideal for line transistors.
• 7. Cooling the transistor and inductor. (cooler and radiator)
• 8. Copper wire 0.10mm - 0.25mm
• 9.Power cord (preferably insulated)
• 10. Plumbing pipe 5cm - 11cm in diameter (small 2.5cm is also possible, but the effect will be worse)

Where can I get what?

You can take almost any diode, and they are in many circuits, most often at the power input as a diode bridge. (If it’s critical, you can try at 1 ampere, but if it gets warm, it’s better to change it)

Capacitors must be on the TV boards and power supply boards of various devices. Zener diodes are most often also found in power supplies.

There are plenty of resistors in all boards, and if you don’t have the required value, you can connect them in series or in parallel.

Field-effect transistors are difficult to find and simply unsolder (they are available in the power supply, but it’s better to buy them), so you can take a bipolar transistor from the TV that is located near the line transformer.

In summary: a TV or power supply is best suited as a donor.

We also do not forget that you can replace all the elements with others and supply not 220 volts, but less, and the result will be the same, but the sparks (streamers) will be smaller.

Manufacturing Kacher Brovina

First, let's wind the secondary and primary coils. We wind more than 1000 turns of thin wire on the pipe. The more turns and the larger the diameter of the pipe, the better the effect. It is very important to wind the coil to the coil, without overlaps and in one layer.

(This is the secondary coil)

We make the primary coil around the secondary coil from the network wire. (5-15 turns) You may not be careful here, but for the sake of aesthetics you can try. You need to wind it in the same direction as the secondary coil.

Next, we assemble the diagram. I assembled everything with a canopy, since there are not many elements and there is simply no point in making a board. The transistor will heat up, so it must be screwed to the radiator; it is advisable to put a cooler on the throttle so that it does not heat up too much.

We solder the coils to the circuit and plug our kacher into the outlet. (220v) If nothing works for you, then you need to swap the leads from the primary coil.

(The one with the thick wire)

When everything is working you will see sparks coming from the wire from the coil. You can touch them with your hands! And other iron objects.

You can also put something iron on top and the power of the coil will increase!

If we bring an ordinary light bulb to the kacher, we will see beautiful plasma in the lamp, like in a plasma ball. (Caution: the lamp gets hot and may burst)

At a short distance, fluorescent lamps and gases in the flasks should light up.

Thank you all for your attention. If you have any questions, write in the comments.

There are plans to create a singing kacher with an interrupter, but this requires materials, and there is currently no money to purchase them.
