Most of my ESP32 projects are there to solve a problem. They control lights, act as voice assistants, or tie into Home Assistant automations that play a part in enabling my smart home to work without ...

This project implements a simple digital oscilloscope using an Arduino Uno microcontroller and a MAX7219 4‑in‑1 8×8 LED Matrix Module. The system samples an analog input signal, converts it into ...

Solarpunk is sometimes thought of as the “good ending” to cyberpunk– there’s technology, but it’s community-focused instead ...

The ionosphere is of great importance to shortwave radio transmissions, since it allows radio waves to be refracted and ...

Abstract: This work presents a 5T2C pixel circuit for active-matrix (AM) micro-displays in near-eye display applications. The circuit supports monochrome micro light-emitting diode (micro-LED) ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...
