Good afternoon, dear ham radio. Each of you at least once in your life wanted to collect a Gauss gan, in other words a Gaussian gun. Today we will consider an option, perhaps one of the simplest schemes for implementing the project. The main part of the Gauss gun is a voltage converter. In this scheme, a fairly simple and powerful voltage converter based on the controller is used.

Gauss gan


The microcircuit plays the role of a pulse generator. Schematic isolation is made in such a way that the microcircuit generates pulses with a frequency of 50 kHz. The voltage of the pulses is 9 volts, this is enough to operate a powerful field-effect transistor. It is advisable to use the field workers of the IRF3205 or IRL3705 series. The transistor is mounted on a heat sink; it is convenient to use heat sinks from AT or ATX power supplies. The power of the converter is 70 - 80 watts, which makes it possible to charge a capacity of 2000 microfarads in almost a second. Used capacitors with a voltage of 400 volts, the total capacity of 4 capacitors is 13,200 microfarads. Pick up a 820 ohm resistor for 2 watts, since it will warm up.

The transformer is wound on cups, although a w-shaped transformer from computer power supplies (the larger one) can be used. The primary winding contains only 5 turns; each core is wound with three cores of wire with a diameter of 0.7 mm. The secondary winding contains only 12 turns of wire with a diameter of 0.4 - 0.7 mm, interlayer insulation is not needed. The peculiarity of this converter is that the charging of capacitors is automatically turned off as soon as the voltage across the capacitors reaches 300 volts. The LED indicates that the capacitors are fully charged.

Gun - made on a plastic pipe with a diameter of 8 - 9 mm. The coil contains 50 turns of wire with a diameter of 0.7 - 0.8 mm. The shells are pointed iron rods with a length of 3 cm and a diameter of 7 mm, they freely enter and exit the pipe. After charging the capacitors, all of their potential is transferred to the coil. Close the circuit with a powerful button for 5 - 10 amperes. At the exit of the pipe, the projectile speed reaches- 50 m / s.
ATTENTION !!! Do not aim the gun at people! the consequences can be tragic, because the power is sufficient for the projectile to penetrate the human body.

Power can be any source of constant voltage, which is capable of delivering more than 3 amperes of current to the load. Supply voltage from 9 to 18 volts (standard 12 volts). It is convenient to use batteries from uninterrupted power. The current consumption of the converter reaches 12 amperes.

    A conventional valdemar transducer is used in flash units.For reference, the capacitor indicated in the circuit costs about 1,500 rubles.
    Question to the author, how did you consider the capacitance and where did you dial 13,200 microfarads at 400 V? Capacitors of this capacity should be at least the size of your battery.
    And how was the speed measured? This speed can only be measured using a speed camera.

    The capacitor is 2200 microns larger than the 0.33 can from the same cola, and here they are at most 5 by 2 cm from

    in my opinion you’ve lost your brain somewhere, the railgun is easier to do, there you’re just getting tired of doing rails, plus there you need capacitors of about 1 kJ, which will cost oh how cheap.

    in flashes, a two-stroke scheme is used on a bipolar transistor, Waldemar Converter only if in powerful professional flashes.
    if there really was a 1kJ capacitor bank, then I would be lying under the table and laughing at this man. Such energy is not always put in a multistage Gaussian.

    We tested such a railgun back in 1994 ... only the name we had was our own electronic sledgehammer. The design may be different. It is based on a powerful high-voltage discharge through an ignitron. The circuit works on diode pulse sharpeners ... There are also industrial machines for stamping, punching holes and welding ... In short, this is our ancient Russian development ... It was licked and remade as a weapon ... But it is unpromising .... .....
