This project details the development of a wireless Arduino frequency meter capable of determining the frequency of AC sinusoidal waveforms between 50Hz and 3kHz. Figures 1 and 2 depict the prototype hardware constructed for the transmitting and receiving functions. Figure 1 shows the transmitting circuit board which incorporates the frequency sensing components. Figure 2 presents

If you spend much time around industrial processes, you may have seen a vibrating bowl feeder at work. It’s a clever but simple machine that takes an unruly pile of screws or nuts and bolts, and delivers them in a line the correct way up. They do this by shaking the pile of fasteners in

Back in the 486 days, it was common to see a “Turbo” button on the front panel of many PCs, which was used to toggle between the CPU’s maximum speed and a slower clock rate that was sometimes necessary for compatibility with older software. Usually an LED would light up to show you were running

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

These days, streaming services are a great way to listen to music or podcasts on your computer or on the go. However, they lack one feature of the MP3 players and streamers of old: visualizations! [mircemk] is a fan of those, and has built a hardware spectrum analyzer that pumps with the music. The build relies

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
4 Methods to Choose Your Right Phased Array Transducer Continue Reading
Infineon adds GaN (Gallium Nitride) to its power portfolio: CoolGaN™ and GaN EiceDRIVER™ ICs. The next essential step towards an energy-efficient world lies in the use of new materials and technologies. Wide bandgap semiconductors enable greater power efficiency, smaller size, lighter weight, lower cost, or all together. Infineon is uniquely positioned in the power semiconductor
