Sometimes it is necessary to obtain an imitation of the sound of a shot (in an electronic shooting range, various toys, etc.). A relatively simple electronic device allows you to simulate the sound of a shot from a firearm.

A noise signal generator is assembled on diode V1. Amplified by transistor V2, this signal is fed to a controlled amplifier (transistors V4 and V6). A key device is assembled on transistor V5.
In the initial state, the transistor V5 is closed, and there is no signal at the output of the controlled amplifier. As soon as a rectangular pulse (negative polarity) arrives at the input, transistor V5 opens and opens the controlled amplifier for a certain period of time. At the input of the transistor V5, a differentiating circuit R5C2 V3R6 R7 is included, which determines the shape of the envelope of the noise signal at the output of the controlled amplifier.
The signal thus formed through the voltage amplifier (transistor V7) and filter 34 (C6C7 R16C8) is fed to the output stage of the power amplifier (composite transistor V8, V9). The filter suppresses frequencies above 5 kHz.
There are no special requirements for the elements of the simulator, it is desirable to choose only capacitor C2 with the lowest possible leakage current (K53-1).
The establishment of the simulator begins with the setting of the transistor mode (indicated in the diagram) for direct current, for which it is necessary to first close the emitter and collector of transistor V5. The selection of the resistor R1 sets the maximum noise level in the loudspeaker B1. Then the jumper is removed from the transistor V5 and soldered to the terminals of the capacitor C2, and the input of the simulator is connected to the negative terminal of the battery. Resistor R6 is selected so that the voltage at the collector of transistor V5 is in the range of 0,08 ... 0,1 V, since this transistor must be in saturation. After that, all jumpers are removed and an impulse is applied to the input - a shot.

Artificial leather for touch emulation
15.04.2024
In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>
Petgugu Global cat litter
15.04.2024
Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>
The attractiveness of caring men
14.04.2024
The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
| Random news from the Archive Schematic diagrams for kombucha
05.03.2023
Cheap, lightweight, flexible yet durable PCBs are essential for wearable electronics. Her future may be based on flexible schedules based on bacterial cultures known as kombucha, or kombucha.
SCOBY (a symbiotic culture of bacteria and yeast) creates a dense, gel-like mass that is held together by the cellulose fibers of the bacteria. In addition to being a popular drink, kombucha cultures promise to be a useful biomaterial.
A team of scientists from the University of the West of England at Bristol used commercial cultures of kombucha to grow bacterial mats and then dried the resulting products, applied to plastic or paper, at room temperature outdoors. The rugs do not tear or collapse even when immersed in water for several days. One of the tested mats withstood oven temperatures up to 200°C, although the material does ignite on contact with an open flame.
The researchers were able to print conductive polymer circuits on dried kombucha mats using an aerosol inkjet printer, and also successfully tested an alternative method of 3D printing a circuit from a conductive polyester-copper blend. They were able to attach small LEDs to electrical circuits using silver-filled epoxy. The circuits functioned even after they were repeatedly bent and stretched.
Unlike the live kombucha mats he has worked with in the past, the dried SCOBY mats do not conduct electricity, limiting its flow to a printed circuit. Rugs are lighter, cheaper and more flexible than their ceramic or plastic counterparts. Their potential applications include, for example, the creation of wearable sensors and other devices.
Experiments last year by researchers at Montana Technological University (MTU) and Arizona State University (ASU) showed that membranes grown from kombucha cultures were superior to commercially available membranes at preventing biofilm formation, a serious problem in water filtration.
