If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a ...

This project provides a discrete transistor implementation of a multi-tone electronic siren, offering an easy-to-build and low-cost solution that replicates alarm effects found in classic two-timer ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Arc generator modules may be small in scale, but they offer big opportunities for hands-on exploration in electronics. Whether you are experimenting with arc simulation, testing circuit behavior under ...

If you’ve worked with germanium transistors, you’ll know that many of them have a disappointingly low maximum frequency of operation. This has more to do with some of the popular ones dating from the ...

Abstract: A new simple two-transistor four-dimensional (4D) chaotic oscillator is proposed using two sub-circuits, i.e. a modified single-transistor Colpitts oscillator, and another single transistor ...

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 ...

Engineers at the Tokyo Institute of Technology (Tokyo Tech) have uncovered some intricate effects arising when chaotic systems, which typically generate broad spectra, are coupled by conveying only a ...
