A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more sophisticated ...

Looking at some anecdotal stories as well as some reasonably valid survey data, it seems that STEM-related subjects are getting serious interest from students at all age levels; STEM stands for ...

Chaotic circuits can arise from either computed (using Analog Computers or Digital Computers) solutions to coupled differential equations or from unstable systems/circuits. A new open-source circuit ...

This repository contains simple yet fundamental digital circuits built and simulated using Cadence Virtuoso. It is intended for students, educators, and enthusiasts who want to understand how basic ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

A transistor tester can be a handy addition to your electronics workbench. This versatile transistor tester design, first presented a decade ago, enables you to quickly assess the functionality of NPN ...

Such are the breadth of functions delivered by integrated circuits, it’s now rare to see a simple small-signal transistor ...

A simple, low-cost autonomous robot car that follows a black line using IR sensors and transistor-based circuits — no microcontroller required. This project demonstrates how to build a line-following ...

While the I²C bus is theoretically capable of running for years without interruption, in practice, sensors eventually “lock up,” halting communication across the entire bus. A simple transistor ...
