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 ...
This noise generator has an adjustable bandwidth and a consistent amplitude no matter what bandwidth is selected. When working on a recent Design Idea for an adjustable filter, I wanted to use an ...
Invincible Season 5 cast grows as Jack Quaid joins as Gravitator, an autodidact engineer whose gravity gun has a documented ...
Among the ways Formula 1 has changed in the 21st century has been its adoption of driver-in-the-loop simulators. It all started in the early 2000s, probably at McLaren, maybe at Toyota or Ferrari; F1 ...
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 ...
In a University of Kentucky laboratory, three small spacecraft stand-ins slid across low-friction air tracks, nudging and pulling one another without thrusters, propellant, or physical contact.
A clock is by its very nature a device for measuring time, and thus it moves forward at a constant rate. But how about in a ...
There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...
The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more ...
This document is aimed at the Arduino developers, radio experimenters, hobbyists and anyone interested in building a receiver based on the Si473X IC family from Silicon Labs. This project is about an ...
