This Arduino flight controller is designed for controlling a drone using an ESP32 microcontroller, various sensors, and PID control loops. It utilizes an NRF24L01 radio module for communication with a ...

Abstract: A machine is required when humans would like to work in different environmental conditions, such as toxic material, remote handling of bombs, health conditions, and sewage treatment. The ...

We’re all used to Bluetooth chips coming in QFN and BGA formats, at a minimum of 30-40 pins, sometimes even a hundred. What ...

A year ago, I’ve design reviewed an MCU module for CAN hacking, called TinySparrow. Modules are plenty cool, and even more so when they’re intended for remaking car ECUs. For a while ...

November 26, 2025: Nothing's changed with the best way to connect a PS4 controller to PC, as you'd expect since it's an older console. It's still a great pad, but if yours is losing some rubber on the ...

For every household name (think Bose and Sonos), there are a multitude of smaller speaker brands releasing everything from multi-room systems that will set you back hundreds to pocket-sized ones that ...

I've been a contributing editor for PCMag since 2011. Before that, I was PCMag's lead audio analyst from 2006 to 2011. Even though I'm a freelancer now, PCMag has been my home for well over a decade, ...

We've tested hundreds of smart home products in more than 20 categories to help determine which ones are best for every room in (and out of) the house. I'm PCMag's managing editor for consumer ...

The ESP32 is a microcontroller that provides an API for Bluetooth A2DP which can be used to receive sound data e.g. from your Mobile Phone and makes it available via a callback method. The output is a ...

Abstract: Distribution systems continue to grow and becoming more complex with increasing operational challenges such as protection miscoordination. Initially, conventional methods were favoured to ...

Bluetooth headphones have not been proven to cause cancer. Research shows that radiofrequency radiation (RFR) from these devices is low and not linked to cancer. Scientists say there is no increased ...
