In the past, demonstrations of standing-wave phenomena could be done using an actual, physical transmission-line setup called “Lecher Lines.” 1 This method required laborious measurements to determine ...

ArdOsc is an awesome Arduino oscilloscope project built using an Arduino Nano and a tiny 1.3” OLED display. Created by maker Peter Balch the Arduino oscilloscope can display data on a computer screen, ...

Cryptography ain’t easy. Seemingly small details like how many times a computationally intensive loop runs can give the game away. [Lord Feistel] gives us a demo of how this could work with nothing ...
