We've talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using ...

The UFC23 sensor from ScioSense offers an ultrasonic flow converter for measurements in water, heat, and gas meters. The sensor comes in the size QFN32 package with a digital SPI interface. It uses a ...

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 ...

AS5600 is a library for an AS5600 / AS5600L based magnetic rotation meter. More exact, it measures the angle (rotation w.r.t. reference) and not RPM. Multiple angle measurements allows one to ...

I’ve just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m range, ±5mm accuracy, and Modbus communication over UART. The 0.15m to 40m ...

The monitoring of slopes’ dynamics is essential to ensure the safety of infrastructures exposed to landslide risk and to develop mitigation strategies. However, it is not always possible to perform ...

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 ...

Interested in audio-related projects? One of the most popular Elektor projects in 2015 was Burkhard Kainka's medium-wave AM transmitter design. Let’s revisit the creative Arduino Uno-based design.

SparkFun has launched a new Qwiic breakout board for the Acconeer XM125 60 GHz pulsed coherent radar sensor that can measure distance to humans even through walls and works at a distance of up to 20 ...
