Comments on the article

The figure shows a schematic diagram of a stroboscope with two lamps that flash alternately. The stroboscope is assembled in the form of two separate blocks. The lamp control unit is made in one housing, and flash lamps are made in the form of separate blocks and can be taken out and installed in different places. The lamps are powered by one common block of high-capacity capacitors, this block is constantly recharged from the 220 V network through a doubling circuit.

The master oscillator is assembled on two elements DD1.1 and DD1.2. it generates rectangular pulses with a frequency of 5...20 Hz. The frequency can be smoothly adjusted by resistor R7. Elements DD1.3 and DD1.4 work as a trigger, controlling transistors VT1. VT2. The control signals are fed to the control electrodes of the thyristors VS1, VS2. opening them one by one. Powerful control voltage pulses are fed through separating capacitors SYU. JV for high-voltage transformers TR1. TP2. which carry out the ignition of the lamps HL1. HL2. The gas in the lamp is ionized and a powerful flash of light occurs, while the storage tank, consisting of a block of capacitors C1-C8, is discharged. Capacitors are charged from the network through a current-limiting resistor R1.

Switch S1 is used to discharge the block of capacitances through the resistor R3 after the end of work. This is to prevent electric shock when the strobe is turned off. The device is powered by 220 V without the use of a transformer. For the supply of control circuits, a parametric stabilizer is used. It is assembled on a current-limiting resistor R2 and a stabilizer on VD3, VD4, C9. The supply voltage level is 14 V.

Pulse transformers TP1 and TP2 are made independently. A ferrite rod with a diameter of 8 mm and a length of 30 mm made of 600NN grade ferrite was used as a core. The primary winding (I) contains 30 turns of PETV 0,25 wire; secondary (II) - 2500 turns PELSHO 0,1. When winding the secondary winding, each layer is insulated with capacitor paper. The ignition electrode for the IFC-2000 lamp is 10 turns of wire with a diameter of 0,5 mm. wound around the bulb.

The parts of the stroboscope are under mains voltage, so the housing and other supporting structures must be made of insulating material. The axis of the resistor R7, which controls the flash frequency, is isolated with a handle with good insulating properties. The discharge of a block of containers is judged by the glow of the indicator diode HL3, which glows when the containers are charged.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

diamond watch 03.01.2005

The German company "GFD", commissioned by Swiss watchmakers, began to make the most important parts of wristwatches from artificial diamonds.

This is an escape wheel (a wheel, the teeth of which, touched by an anchor fork, allow the entire mechanism to gradually turn) and a balance hair - the thinnest spring that supports balance fluctuations. Diamond parts are strong, characterized by reduced friction and wear, and almost do not change dimensions with temperature changes.

The company is silent about the manufacturing technology, indicating only that "no force is used in the process and no sawdust remains." Most likely, the details are cut from thin plates of synthetic diamond with a laser beam.
