Sometimes a clever hack of an off-the-shelf product can come courtesy of its dismantling and hardware modification, but at other times the most elegant of hacks can be made without ever turning a screwdriver. [Brian Lough] was given the request by a friend to replicate a commercial child’s night light that changed colour with temperature, […]

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive. That’s good enough for AM radio, anyway, but you’ll need to try this DIY FM receiver if you want to listen to something more

Sometimes, the best hifi gear is the gear you’ve already got. This is particularly the case in the cassette world, as high quality decks are long out of production. [Nick] liked his current rig, but wanted to be able to use it with a remote from across the room. Naturally, he set to hacking the feature

I’m a big fan of the ESP32 boards because of the number of communication options they managed to squeeze on the board, but I became more impressed recently when I came across the TTGO LoRa32 development boards which adds LoRa to the onboard communication features of the ESP32. The LoRa communication capacity of the board opens up a web

SkyTraq announced a 12- x 16-mm size PX1122R multi-band RTK receiver for centimeter-level accuracy GNSS positioning applications. The receiver works with all the four global navigation satellite systems using GPS L1/L2C, Galileo E1/E5b, GLONASS L1/L2, and Beidou B1I/B2I signals concurrently to maximize positioning availability even in difficult urban environments. Based on single-chip SoC design, PX1122R

In this tutorial, I will show you how to achieve wireless communication of variables between 2 Arduinos using the HC-12 module, that operates from 433,4-473 Mhz. HC-12s are wireless modules for arduino to arduino communication, because they can send multiple variables over long distances-ones up to 1km-using only 2 digital pins, not even PWM pins,

The newly released CDP-TX-07M and CDP-RX-07M inherit the compact, high-functionality, high-quality characteristics of their first-generation models with updated internal circuit design for the long-term stability and life needed for industrial applications. Saelig Company, Inc. has announced the compact, multi-channel CDP-07M UHF Narrow-Band Transmitter/Receiver Pair: CDP-TX-07M (transmitter) and CDP-RX-07M (receiver). The modules contain almost all of the components necessary for radio transmission

Contributing to delivery of wireless communication services that are stable over long distances and while moving at high speeds. Tokyo, Japan—Sony Corporation today announced the upcoming release of the CXM1501GR communication module, which is compatible with the ELTRES™ low-power wide area (LPWA) wireless communication standard that Sony has developed for IoT applications. Equipping IoT devices with this communication module enables them

Description: Serial communication between two Arduino boards – This tutorial covers the process of establishing serial communication between two Arduino boards. While the Arduino Uno or Arduino Mega typically suffices for various projects such as CNC machines or 3D printers, instances arise where a single board isn’t adequate to complete a project. In such scenarios,
