Whenever you hear the transformerless supply term, you initially imagine the capacitor-based solution, which means a high voltage capacitor in series with the mains line, then a bridge rectifier, a Zener diode, a filtering capacitor, and so on. Such a circuit is not just able to deliver...

An ultrasonic range finder is a useful tool in a variety of real-life and robotic applications, such as in obstacle avoidance and distance measurement systems. The ultrasonic range finder measures the distance by emitting a 40KHz pulse of ultrasonic sound that travels through the air until it...
What are the characteristics that make a good electron tube? I understand that the purpose of an "electron tube" is to act as an amplifier or an electronic switching component for high power systems, but what is the ideal composition of one? Schematically they are comprised of a cathode, a grid...
Since the site rejected my disclosure of that explanation of an innovative approach to energy conservation; I won't use this site for any purposes other than the usual SCOTUS.

Most systems today involve both analog and digital components, and digital components in a lot of cases would be communicating with each other via some form of serial communication interface (I2C, UART, SPI or any other). In such a scenario it might be useful to have a way to simulate these...
Unfortunately in 2019 I decided to end selling on ebay. There is many reasons to that. I have left all my electronics things in the UK. Now only recently I started over again from zero, bought a soldering station and some parts. I have a new project. a 7segment LCD glass controlled by a...
