Inside one of my retro treats, the Soviet calculator Электроника МК-52, about which I have already prepared an article“Электроника МК-52 – Soviet calculator in orbit”, as well as in some respects its twin design Электроника МК-61, one can find rather mysterious-looking integrated circuits.
If one Internet trivia site is to be believed, the most manufactured thing in the world is a transistor. This may be true, but the authors of this information must have also taken into account those placed inside silicon cores, although they are not single elements. After all, in discrete circuits there are at least two resistors per single transistor, also the Internet fact can be questioned quite easily. However, whatever one may say, transistors in one form or another are quite common in electronics. It is thanks to them that a whole branch of digital and logic circuits was created, which, along with increasing computerization, have become the building blocks of the modern world.
Some time ago on one of the popular auction sites I noticed a rather interesting offer. It was a module of unknown origin with a small VFD lamp, which I suspect was the seller’s main motivation to get rid of it. After all, fluorescent designs sell quite well, though not as well as Nixie lamps. …
When taking DC voltage measurements with a multimeter, we usually don’t think about its accuracy. Receiving a result of 5.1V, when we expect something in the neighborhood of 5V, we assume that the multimeter’s indication is correct, telling ourselves that simply at the output of the power supply or the USB port of the computer …
In today’s world, the importance of various types of devices from the “smart home” category is growing day by day. There is nothing surprising in this, after all, thanks to these, sometimes very simple equipment, we can remotely control home lighting, heating or ventilation. Besides, thanks to all kinds of sensors, reading temperature, humidity and light intensity has become much simpler. The data collected by the system can be used to intelligently manage actuators such as relays. In other words, today’s technology allows us to build really complex structures at a low cost, which we can call a smart home.
Modern microelectronics is one of the fastest growing areas of science and technology. Its relevance to our daily lives is immense, as it is thanks to microelectronics that we can use advanced electronic devices, such as smartphones, tablets and laptops, which have become an integral part of our reality. In today’s article, we invite you to take a deeper dive into the fascinating world of silicon, where we will consider the construction of elements such as transistors and diodes.
The modern world is constantly flowing toward the future, driven by incredible advances in technology. Central to this dynamic process is the electronics that underpin most everyday devices. One of the key foundations of electronics are structures called integrated circuits, which have been revolutionizing our ability to process information and communicate for years. However, when we look deep into electronic chips, we see that they are made up of structures such as transistors, diodes, resistors and even capacitors. These elements are placed together, on a single piece of silicon, which makes them significantly different from similar structures placed on printed circuit boards. In this article I will tell you a little about silicon electronic structures, the foundation of today’s technological world.
In today’s dynamic world of electronics, we are constantly using advanced technologies that enable us to perform tasks faster, more efficiently and more conveniently. One of the most remarkable developments that has affected our daily reality is the invention of the integrated circuit. These small but powerful electronic components, typically containing hundreds, thousands or even millions of elements on a single silicon wafer. Chips have revolutionized our world in ways we could not even imagine before. But in order to explore the history of integrated circuits, we need to go all the way back to the 1920s, to the days of tube designs.
Today I have for you another material in the series about the integration of ESP8266 modules with Apple HomeKit. This time I’ll talk about how to connect and control the popular WS2812B programmable RGB LEDs.
There are quite a few different types of smart home systems, also known as smart home. Each has its own advantages and disadvantages, and choosing the right system really depends on the individual user’s preferences. One such system is HomeKit from Apple. In this and subsequent materials in this series, I would like to tell you a little about how to integrate HomeKit and the well-known ESP8266 modules. I will show you how to configure such a module so that its operation can be controlled from an iPhone, MacBook or Apple Watch. In addition, we will connect to the outputs of our microcontroller various peripheral modules, the operation of which will be controlled by ESP.
