• OpenScope MZ

    Recently I became the owner of Digilent’s OpenScope MZ measuring board. Every electronics, whether amateur or professional, needs to measure different electrical values. Sometimes it needs to generate a waveform at a given frequency. And even if he is a professional, he does not always need professional oscilloscopes or generators for such things. Sometimes simpler solutions are enough. For such solutions, in my opinion, it is the Open Scope MZ.

  • Encoder – how to use it?

    Most devices communicate with users in some way. Sometimes it is a blinking LED. Sometimes displaying a message on the display. Sometimes it is a requirement to press a button. And another time you turn the knob of the potentiometer. Another way to communicate with the user is the encoder. What is an encoder? The external appearance is similar to the potentiometer. And it is very easy to confuse him. However, his principle of operation is completely different. So how does an encoder work? In a very simplified way, this picture shows: In the figure, we see only a piece of the encoder. We see two circles (A and B)…

  • Script generating project files

    I mentioned in one of my posts about how I call my projects. It’s about naming folders, schemes, PCB designs and BOMs (Bill Of Materials). I used to do everything manually by myself. I created a folder, created the schema as a new one and saved it under the proper name. I did the same with other files and folders.

  • TINA-TI – adding an element model to the schema.

    I wrote about how to add elements to the schematic in LTSpice in this article: http://sigaris-electronics.eu/2018/11/ltspice-adding-an-element-model-to-the-schema/ . In this post I will describe how to add an element in Tina-TI from the official model from Texas Instruments.

  • My way of naming electronic projects

    In order not to get lost in our own projects, we must in a logical way call and label them. Everyone has their own way. In this post I will present my way to naming projects as well as describing PCBs. I met this method in one of the companies in which I worked as an engineer and in my opinion it is simple, clear and intuitive enough that I decided to use it also in private projects.

  • LTSpice – adding an element model to the schema

    LTSpice has a large built-in library of elements. But sometimes we need an element that is not in the library. Electronics manufacturers themselves provide models of elements that they publish in the form of text files.The easiest way is to add an element to the library. But sometimes I want to be able to send someone a simulated circuit. In this case, we had to attach all the elements in the library, and someone else would have to import it. But there is another way out of this situation and I will present this solution.
