Telecommunication protocols: OSI model (continued)In the previous part (link), we divided all the layers of the seven-layer OSI model into two groups. We examined the first four layers that…1d ago1d ago
DAC0832 Digital-to-Analog ConverterDigital-to-analog converters (DACs) are often built into microcontrollers but tend to be slow, noisy, and lack resolution. So, we…Nov 11Nov 11
Using PLC on DC power linesModern energy systems are circling back to direct current but with a fresh, tech-savvy approach. Solar power generation, for example, is…Oct 22Oct 22
Between Analog and Digital: ComparatorsSometimes, there’s a need to compare two voltages. A special circuitry stage exists to serve just this purpose — a comparator. Today, I…Sep 30Sep 30
Disadvantages of Mean Well LRS series power suppliesThis post will not include information about power supply heating, ripple size, etc. Because it is all in the previous post…Sep 23Sep 23
Telecommunications Protocols: Open Systems Interconnection (OSI) ModelUsually, the analysis of communication protocol stacks begins, relatively reasonably, by considering the seven-layer Open System…Sep 16Sep 16
How does logic work? Decoders and DemultiplexersGreetings to all the fans of microcontrollers and digital chips! Today, we will get acquainted with decoders and demultiplexers that allow…Sep 10Sep 10
PLC: data transfer over power linesIn electrical networks, the voltage typically alternates at a frequency of 50 or 60 Hz or is direct current. However, power cables can also…Sep 4Sep 4
How does logic work? The magic of the CD4017 decimal counterHi there! In the previous post, we talked about binary counters. They count like this: 0000b, 0001b, 0010b, 0011b, 0100b, 0110b, 0111b…Aug 31Aug 31
We’ve created a controlled resistive load. But why?!But for real, why? After all, there are many ready-made devices for this role. And even if you do make one, everyone knows that the best…Aug 25Aug 25
