The best lighting effect for a party: strobe. Over the past 3 years, I have collected about 15-18 strobe lights, everyone is delighted, although some do not like the quality of workmanship ... Hmm ... for 100 crowns (the price of one of my first ones) is quite an acceptable operating time of 10- ... discos.
Strobe circuit
Important features
There are a few things to keep in mind when assembling. So, the input resistance (the one that is 100 ohms) is ideally made from a 500 watt cooker coil... it heats up a little and has a resistance of exactly 100 ohms.
A capacitor can also be used with 100 uF ... this should increase the flash power, but it’s better not to do this, because the lamp burns out faster, and the power increases by 20 percent ... in short, it’s not worth it, it’s better to take a more powerful lamp.
The transformer is wound on any core, the main ratio of turns is 1/100 ... For example: on a segment of a ferrite rod (this is a magnetic antenna in a radio) let's say 40 mm long, with a diameter of 8 mm we wind winding 2 (400-500 turns of wire 0,3-0,6 .1 mm), wrapping after each layer with an insulator (wide adhesive tape or electrical tape, you can just use paper), and then winding 5 (6-0,8 turns of wire thicker than 1,0-XNUMX mm).
The setting is as follows: If there is voltage on the capacitor (about 300V), the thyratron (MTX-90) blinks, and the strobe does not flash, then: 1) either the transformer does not work 2) or the thyratron is covered 3) Or somewhere incorrectly assembled.
Light bulb wiring
If you disconnect the wires from the capacitor from the lamp, leaving it connected only to the transformer, then when turned on, the lamp will glow slightly blue ... if it does not glow, then high voltage is not supplied or it is too low. It is ideal to find an ISK-250 or IFC-2000 lamp for a stroboscope. There are also lamps (I have never seen them, but they exist): IFP-200,500,1500,4000,15000 J ... IFB-300 J ... IFT -200 J ... IFC-15,20,50,120,500,2000 J. It is probably clear that the lamp used from the IFC-120 flash emits only 120 J of energy, and for a COOL strobe you need a larger light bulb.

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, ... >>
| Random news from the Archive Indoor positioning technology
06.02.2014
Prima Research has patented a technology that allows you to track any radio-emitting device in three dimensions, such as mobile phones, tablets, RFID tags or computers.
The problem of navigation inside buildings, tunnels and other spaces closed to GPS signals is very relevant in the light of the spread of new services and geographic information systems. Most existing navigation technologies operating in such conditions are designed to work in two-dimensional space, that is, with conventional two-dimensional maps. This is usually sufficient for most tasks. However, inside buildings and other enclosed spaces, XNUMXD navigation is required. In addition, the passage of high-frequency signals is difficult, and reliable positioning is a difficult problem.
Prima Research's new technology enables highly accurate navigation with a minimum array of 4 synchronized receivers, a reference receiver, and an appropriate signal processor. The receivers form a tetrahedron that tracks the movement of any electronic radio emitting devices and determines their location. In small volumes, such as a single building, the positioning accuracy is very high and can be less than 1 cm. By increasing the network of receivers, it is possible to expand the observed space to infinity.
The advantage of the system is that it is able to detect any device without the need to install software on it. Thus, the system receives information about the location of the device, but not information about its owner, while maintaining privacy. The Prima Research navigation system can detect a mobile phone in a passing car or a person with an RFID tag entering a room, but the system does not receive the person's phone number or identity.
The unique digital sequence assigned to a new device is arbitrary and does not correlate with any personal information. From a legal point of view, Prima Research's new navigation system does not pose any problems because it does not work with confidential information and thus is not subject to relevant legal restrictions.
Because Prima Research's signal processor can work with any communication network, WiFi, 3G, 4G/LTE, unlicensed spectrum, etc., navigation can be provided for any device. This is critical for commercial services, law enforcement, emergency services, and other applications that need to work with as many devices as possible. Prima Research navigation avoids compatibility issues, potentially expanding the scope of this technology.
