A frequency generator is a very handy device in electronic design, development, testing and trouble shooting. It is such a kind of device which can generate the required frequencies which can be then applied directly to the target device for testing it. There are frequency generators which can generate the required waveform like sine wave,

I have a solar power installation using an Omnik string inverter. Omnik is a China based manufacturer of PV inverters and they make extremely efficient devices. Optionally, you can install a WiFi module to make it “connected”. I am very content with the device, with two notable exceptions. It “phones home” to a China based

What would you think about a program, made in the C language of the Arduino IDE, that makes the LoRa radio change frequency? This is what you will learn about in my video today, where you will learn about the differences between LoRa radio, LoRaWAN protocol, and encryption. We will then create a project featuring

Although nowadays many portable devices (smartbands, smartwatches, smartphones,…) are available that can detect the Heart Rate (HR) and perform trace analysis, chest strap belts-based systems (like the one in the upper part of thr picture) are still widespread and used, but lacking the possibility to record and export the trace of the measurements. In my

Introduction Modern phased array transducers for industrial NDT are usually made from piezocomposites, which in turn consist of many small thin segments of piezoelectric ceramic embedded in a polymer matrix. Phased Array Transducer comes in a wide variety of shapes, sizes, frequency ranges, and a number of elements. This technology is most often used to
