The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more ...

We often feel that we are "on the same wavelength" with one another, but can science identify and engineer this phenomenon?

How microcontrollers and single-board computers coordinate high-speed RF acquisition and generation. How SCPI and UART commands let simple controllers use advanced measurements without FPGA ...

Although it dates back to the early days of the Marconi Company in the 1920s, the Franklin oscillator has remained a relatively obscure circuit, its memory mostly kept alive by ham radio operators who ...

I'm trying to get block detection working on my HO scale model railroad. I found this page and liked the idea of using current transformers to detect the Digital Command Control signal inducing ...

Abstract: Slope monitoring systems using a wireless sensor network is an efficient technique to track slope movements or failures. Instability in slope contributes greatly in hazards caused to lives ...

Audio frequency detection is the process of identifying the pitch or dominant frequency of a sound signal. Three common methods used are Fast Fourier Transform (FFT), AutoCorrelation, and ...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor ...

This project demonstrates an Arduino-powered wireless frequency meter that can measure the frequency of sinusoidal AC transmissions ranging from 50Hz to 3kHz. Figures 1 and 2 show prototype ...

Jumperless V5 is a one-of-a-kind, programmable breadboard based on a Raspberry Pi RP2350B microcontroller that lets you skip the jumper wires and jump right into prototyping. It is described as “an ...
