This project is a simple, variable-frequency sine wave generator built on the Arduino platform. It uses Pulse-Width Modulation (PWM) to produce a digital approximation of a sine wave, which is then ...

Strictly speaking, a Theremin uses a pair of antennae that act as capacitors in a specific R/C circuit. Looking at [aritrakdebnath2003]’s MIDI THEREMIN, we see it works differently, but it does play ...

Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

Later, I helped a friend disassemble a Tesla model, and the mass of circuit boards inside was overwhelming—until I drew 5 ...

Environment Variables are responsible for storing information about the OS’s environment. Different apps and programs require different configurations and it is the job of Windows to ensure that each ...

If you want to see or check the names and values of Environment Variables in Windows 11 or Windows 10, here is how you can do that. There are mainly four ways to find almost everything about the ...
