Electronic magazine “COOLER”or
Website simple interesting radio circuits, is dedicated both to professionals involved in the design and assembly of complex electronic digital devices, and to beginner radio amateurs taking their first steps in electronics, trying to understand the principle of operation of radio components - transistors, microcircuits, pic and avr controllers. The site contains only proven radio circuits of simple LED effects, alarms and power supplies. A large section contains descriptions of metal detectors of all popular home-made models - Terminator, Tracker PI-2, Chance and, of course, the famous volksturm, with the assembly of which begins the path of many radio amateurs specializing in assembling equipment for treasure hunting. For novice spies, we have collected a large collection of proven circuits for bugs and radio microphones - on transistors and specialized microcircuits. All diagrams are provided with drawings printed circuit boards And detailed description transmitter settings.
It should be remembered that a powerful FM bug can interfere with FM broadcast radio stations, so try to respect the law. A pressing problem today is the issue of selection and operation of chargers. Now almost any electronic portable equipment, including mobile devices, battery powered. At the same time, the types, voltage and other parameters of the battery may vary greatly. Therefore, assembling a homemade universal charger will be completely justified, especially in the event of a breakdown of a rare standard one that is not available for sale.
In our age scientifically technical progress, when the development of electronics and radio engineering is increasingly miniaturized, mastering the work with microcontrollers of the popular pic and avr series will be mandatory. Using the ATmega MK, you can create small and very functional devices that would have dimensions 10 times larger if they were made using transistors and conventional digital chips. Simple programmers, the basics of microcontroller firmware and interesting circuits on pic16f84 - all this is on the radio circuit website. Despite the large number of other radio technical resources for beginners - radio cat, soldering iron, radio pilot, we try to introduce you to you with the highest quality and quickly useful diagrams and the latest in radio technology. Progress does not stand still, and now such a traditional area as lighting has begun to change and improve every year. In just under 10 years, the incandescent lamp has undergone an evolution, first into a fluorescent lamp, and then into an LED lamp. How to choose or make your own LED light bulb, lamp or flashlight - see the LEDs section. And if you have a question about finding the right schematic diagram
or setting up the operation of a device you assembled yourself - contact the forum, where our moderators will quickly and professionally advise you on any amateur radio issues.
Parametric voltage regulators are still used to power low-power electronic products, so it is necessary to be able to calculate them.
Often, when repeating finished structures, the operating conditions of which differ from those recommended by the developer, it is necessary to analyze the operation of the parametric voltage stabilizer to clarify the resistance value of the ballast resistor.
These problems were solved using a file developed by the author in Microsoft Excel. Two options for calculating a parametric voltage stabilizer and a calculation for analyzing the operating conditions of a zener diode in a finished circuit are presented.
The objects of calculation and analysis in the examples are parametric stabilizers of two well-known designs of power amplifiers audio frequency. This is from Interlavka and from Andrey Zelenin A.
In commemoration of the 50th anniversary of the invention of radio by the Russian scientist A.S. Popov, celebrated on May 7, 1945, the Council of People's Commissars of the USSR decided: given the most important role of radio in the cultural and political life of the population and for the defense of the country, in order to popularize the achievements of domestic science and technology in the field of radio and the promotion of amateur radio among the general population, establish the annual “Radio Day” on May 7.
From the Resolution of the Council of People's Commissars of the USSR
dated May 4, 1945.
On May 7 (April 25, old style), 1895, Russian engineer Alexander Stepanovich Popov, at a meeting of the Russian Physical and Chemical Society, demonstrated a spark wireless transceiver radio system that allowed the exchange of information signals.
In the hustle and bustle of everyday affairs, we somehow forget about significant dates. And this date should be remembered and proud. This is our life, our bread, our hobby.
Once again, everyone who is in one way or another connected with electronics, Happy Holidays!
Hello friends! Probably everyone has spent the night at least once with a soldering iron in their hands amidst clouds of rosin smoke, driven only by the idea of creating something special, new, sounding or working differently from others. How many microcircuit pins were cut off after repeated soldering, how many chips were killed by static electricity after scratching the head!
I’m sitting one evening, looking at the microcircuits sent for me in the online store, which at best will arrive in a week or two, and suddenly the question arises in my head: “Is it possible to somehow speed up the process of developing a device, yes, so that you can immediately show it to the customer?” At that time, I had just been ordered several accessories for an electric guitar. And I, having enough experience in handling the Proteus circuit creation and modeling system, decided to resolve this issue with the help of this program.
Progress, as we know, does not stand still. Especially in electronics.
In our times, when you can easily fit half a computer on a square centimeter of a board, and special programs allow you to virtually “test” the developed device without ever picking up a soldering iron and a tester, this article may seem hopelessly outdated.
But who knows - maybe it will be useful for some beginners.
Well, let the experienced ones perceive this text as another tale about how the surviving radio destroyers live in the remote wilderness (the Far East, very distant), where I think civilization will not reach very soon.
There are sites on the Internet called photo banks. There are quite a lot of them. But one leaves a simply mesmerizing impression on me. The life of the first half of the past and some moments of the century before last have frozen. And the quality of the photos is great!
I won’t spend too much time on antimony, I’ll just share a couple of photos that I liked. Moreover, they are directly related to our topic.
The caption under the photo in the photo bank reads:
June 1924 Carl W. Mitman, Technical Curator of the United States National Museum (Smithsonian Institution) holds what was probably the first radio tube, made in 1898 D. McFarlane Moore* from New York. The radio waves emitted by this lamp launched a bomb that destroyed an entire block and demolished a small copy of the battleship Maine.
Once again, looking at the homemade “noodles” from a computer, amplifier, speakers, etc., a completely spontaneous thought was born - “why can’t the wires be something that won’t spoil the interior”?
The idea was born quite quickly. But the virtual implementation took a lot of work: about 5 hours of modeling and rendering.
But we're not talking about 3D modeling.
Dear Datagorians, in your opinion, is the idea worth implementing?
What are its pros and cons?
This is a translation from Ukrainian article that I decided to introduce the Datagorians to when I read
Photo by Alejandro Gonzalez Novoa
Author of the article V.L. Karlash V accessible form explains the advantages of different loudspeaker drivers based on their technical characteristics. However, the article is purely technical (the author is a candidate of physical and mathematical sciences) and, in general, does not take into account the acoustic design of the loudspeaker, as well as such important concepts in modern amateur radio practice, such as “I like the sound - I don’t like it”, “expensive - expedient."
It is also worth considering that it came out in 1983, when some models of our speakers did not yet exist, and Soviet radio amateurs had no idea about many good foreign speakers (unfortunately).
I know from myself, if some design doesn’t work out, or if there’s no fault in the TV, amplifier, and... well, the mood is not right - you need to “switch” to something else, get distracted. Then, with renewed vigor, everything will go like clockwork.
I suggest you all take a little break from amateur radio affairs, please yourself and your relatives, or give a gift to your friends.
Hello friends!
Do you love role-playing toys? RPG? No, I’m not asking - you sit in them for days, abandoning your affairs and forgetting about your responsibilities. Time for business, time for fun. I'm asking if you know what they eat it with. After all, if not, then you will not be able to fully experience all the laughs described below.
Famous studio Bethesda just released the game The Elder Scrolls V: Skyrim, which swept around the world with foam and pathos, receiving maximum ratings and scores from critics and players.
It's no secret that toy developers go out of their way to try to bring their games closer to reality.
And not just in terms of graphics. Graphics are simply a matter of technology: home PCs are becoming more and more powerful, the graphics are becoming more and more beautiful, and now a transparent tear is running down your rosy cheek, covered with pores and downy hair, and the bottomless sky, the sun and who knows what they have drawn there are reflected in it...
What is this?
This is a youth, student open-air festival that has been held annually in the Altai mountains for 15 years. It is unique in its own way, since the festival format combines many areas. In two and a half days, from the main stage (and there is also a smaller, alternative), a crazy mixture of performances pours out non-stop: KVN performers, rappers, DJs, dance groups, rockers (from rock and roll to alternative), and something else fun.In the clearing during daylight hours you can meet painted people (body painting), buy paraphernalia and something exclusive (handmade fair), take part in seminars, watch a costume competition, and graffiti artists paint everything they can spray on. And with the onset of darkness, firemen put on a truly mesmerizing fire show. And, of course, fresh air, the nature of Altai...
