This article explains an upgraded smart solid-state AC switch system that uses microwave Doppler radar instead of traditional ...

In this project, I present a simple and efficient circuit based on an ATtiny85, capable of converting an analog voltage into a digital frequency (V/F). This small module allows me to measure the ...

If you want to protect a system from being hacked, a great way to do that is with an airgap. This term specifically refers to keeping a system off any sort of network or external connection ...

I’ve been working with computers for ages, starting with a multi-year stint in purchasing for a major IBM reseller in New York City before eventually landing at PCMag (back when it was still in print ...

The LED matrix 8x8 is a system of 64 interconnected LEDs that, with the help of the MAX7219 LED driver, light up as programmed, and all of this is located on one board and is truly easy to use. You ...

A cheap USB-programmable analog output is great for setting intensities, power levels, or general analog signalling in many experimental contexts. There are lots of solutions when you want one or two ...

Abstract: In this work, the accelerated aging experimental tests of LED samples packaged with different kinds of LED chips were carried out under 85°C/85% relative humidity (RH) moisture condition. It ...

Abstract: This paper highlights the benefits of employing active LED drivers with reduced power processing to improve efficiency. These drivers are equipped with power-factor correction and ...
