First-person-view (FPV) flying, by adding a camera, video transmitter, and video goggles to the meat on the ground, is one of the best ways to experience remote-controlled flight. For just a few ...

This project is a Fixed Fast Fourier Transform (FFT) Spectrum Analyzer built using an Arduino Nano, a 0.96" OLED display, and a MAX9814 microphone module. The analyzer visualizes audio frequencies ...

This project provides a cost-effective solution for analyzing the RF spectrum in the 300-450 MHz frequency range. It is ideal for hobbyists and professionals working with ISM band devices, such as ...

Every machine has its own way of communicating with its operator. Some send status emails, some illuminate, but most of them vibrate and make noise. If it hums happily, that’s usually a good sign, but ...

Tektronix has introduced a family of multi-function mixed-signal oscilloscopes that can be configured into spectrum analysers. As with previous generations in the MDO4000 series, the MDO4000C provides ...
