The parts arrived for the RPM meter that uses an Arduino and reciprocal counting to get a three-times-a-second update rate with 1rpm resolution. Arduinos plus ready-made modules are a very qick route ...

The tiny violin is made of platinum and is just 35 microns (35 millionths of a meter) long and 13 wide. To put that into perspective, a human hair is typically around 17 to 180 microns in diameter ...

After this tedious step, he designed a PCB that hosts an Arduino Nano to accept input, two MCP23017 GPIO expanders to give it enough outputs, and CD4066BE CMOS switches to trigger the connections.

This letter analyzes and compares the performance of full-duplex relaying (FDR) and half-duplex relaying (HDR) for ultrareliable short-packet communications. Sp ...

Then we get our hanHere’s the full list of power banks we've tested, which range from small wireless banks to large, multi-device batteries. Amy Skorheim for Engadget MagSafe-compatible ...

Traditional self-interference cancellation (SIC) methods are common in full-duplex (FD) integrated sensing and communication (ISAC) systems. However, exploring new SIC schemes is important due to the ...

The Raspberry Pi is a popular single-board computer (SBC) and often the star of the show when you need a powerful brain and control hub for your DIY programming projects.. However, many Raspberry ...
