It’s always nice to simulate a project before soldering a board together. Tools like QUCS run locally and work quite well for ...

Making airplanes with foam board is really handy since this material is very cheap, easy to work with, and durable. It's the same material the channel Flite Test uses in their builds. I recently tried ...

In part 3 of this series, we used Kirchhoff’s voltage law to derive the branch currents and node voltages for an unbalanced Wheatstone bridge with five known, fixed resistors (Figure 1). Now, we ...

There’s a long history of devices originally used for communication being made into computers, with relay switching circuits, ...

Abstract: Due to the increasing threats from possible large-scale quantum computers, post-quantum cryptography (PQC) has drawn significant attention from various communities recently. In particular, ...

Abstract: Low-noise current readout circuits are essential in modern scientific and industrial applications ranging from nanopore sensing to quantum systems. This tutorial-style paper presents a ...
