Back in the 486 days, it was common to see a βTurboβ button on the front panel of many PCs, which was used to toggle between the CPUβs 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 …
An interesting aspect of time-varying waveforms is that by using a trick called a Fourier Transform (FT), they can be represented as the sum of their underlying frequencies. This mathematical insight is extremely helpful when processing signals digitally, and allows a simpler way to implement frequency-dependent filtration in a digital system. [klafyvel] needed this capability …
OMRON Corporation ofΒ Kyoto, westernΒ JapanΒ globally released its new MOS FET (*1) relay module βG3VM-21MTβ onΒ December 2, 2019. The product is the first electronic component in the world (2) to adopt a βT-type circuit structureβ (3). With a T-type circuit structure consisting of compact-size and longer-lifecycle solid-state relays that output signals using no physical contact, the relay …
