• Silicone mat for soldering

    The hot-air soldering station is already almost standard equipment in the electronics workshop. To use it safely, the environment must be well protected from high temperature air. One such protection is a silicone mat recently bought by me.

  • Local Redmine installation

    Work on the project is inseparably connected with work on various tasks. To facilitate your work on them, it is worth having a tool that will facilitate task management. One of such tools is Redmine. Many engineers in their work met with Redmine. They have become accustomed to this tool and would also like to use it in home projects. Redmine is server software. So either we need to look for someone who will make Redmine available to others (usually a paid option), or to buy hosting and install it there (we have to pay for hosting), or install it locally on the computer. Because we are talking about home…

  • Import SPICE model into TINA TI.

    One of the most popular programs for simulating electronic circuits is PSPICE. Most manufacturers of electronic components do not have their own simulation programs. But in order to facilitate the work of engineers, they provide PSPICE models of their products. Fortunately, we are not limited only to PSPICe. In this post I will show you how to import PSPICE models into TINA TI.

  • [TINA-TI] Sweeping parameters.

    One of the incredible advantages of electronic circuit simulation programs is the ability to see how our circuit will behave when we change the parameter of an element in a circuit. And it’s even better if we can see on one chart the circuit response to different values of this element’s parameter. Let’s see how it is done in TINA-TI.

  • 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)…
