Build festive decorations using Arduino and Raspberry Pi with these five creative holiday projects and video tutorials ...

An hourglass tells you what it is in the name — a glass that you use to measure an hour of time passing by. [EDISON SCIENCE CORNER] has built a digital project that mimics such a thing, with little ...

If you’ve got an RTL-SDR compatible receiver, you’ve probably used it for picking up signals from all kinds of weird things. Now, [Jaron McDaniel] has built a tool to integrate many ...

The UM3750 chip and clones were used in many applications, ranging from alarm systems and automated gates to smart sockets. These microchips generate only a baseband output waveform: the actual ...

Abstract: Low-cost tethered buoys are important for seawater observation, coastal area monitoring, and pollution sensing. Underwater sensor networks operating at 433 MHz (ISM band) suffer high ...

Arduino project for receiving and (in the future) transmitting signals using a 433 MHz RF module. Currently, this repository contains code for a 433 MHz signal receiver, which allows reading signals ...
