- Электроника 22-01 – Soviet travel clock
Today, few people remember such a thing as travel watches anymore, although those in the days before the spread of cell phones were readily used. One such device was the Soviet design Электроника 22-01 (Elektornika 22-10), which we will take a closer look at in this article.
- STM32 Ethernet – UDP Server
Recently I had the opportunity to work on some project using STM32 microcontroller and Ethernet interface. Probably like other people undertaking this topic, I encountered a problem - the lack of “simple” tutorials. In most of the available sources, connecting the Ethernet interface and STM32 chips is described quite confusingly, and in my opinion, there is a lack of instructions describing how to configure this functionality in the simplest possible way, without unnecessary exploration of network aspects. That's why I decided to prepare this and related material covering the topic of Ethernet on STM32. In this article I will show you the basic functionality of the UDP server.
- Intel’s forgotten registry
What was the name of the first personal computer? The answer to this question depends on the answerer. According to the Computer History Museum located in Silicon Valley, it was the Kenbak-1.
- STM32 Ethernet – the first launch
Recently I had the opportunity to work on some project using STM32 microcontroller and Ethernet interface. Probably like other people undertaking this topic, I encountered a problem - the lack of “simple” tutorials. In most of the available sources, connecting the Ethernet interface and STM32 chips is described quite confusingly, and in my opinion, there is a lack of instructions describing how to configure this functionality in the simplest possible way, without unnecessary exploration of network aspects. That's why I decided to prepare this and related materials covering the topic of Ethernet on STM32. As a first step, I will show you how to perform the initial configuration so that the microcontroller is visible on the network.
- The display that turned out to be more
Browsing popular auction sites, I once came across an offer for a display similar to those manufactured in the 1970s and 1980s. It was described as our indigenous CEMI design, although the “NN” logo, denoting National Semiconductor, was visible on the board. Of course, this type of design was produced in communist Poland, although not on a large scale, it is much more common to find displays from Czechoslovakia, where production volumes were larger. So, I think one can forgive the seller's marketing gaffe of labeling the element as a CEMI production, although this is also some misrepresentation. Nevertheless, the price of the item was quite low, so I decided to order it, and in this article I will tell you about its construction and the adventures of trying to get it to work.
