By Antonio Velasco, it was actually to build a weather station as part of UC Irvine’s Open Project Space. But he wanted to experiment more generally with comms for applications involving the use of outside sensors or controllers. Basically, it’s an introduction to Nordic’s single chip 2.4GHz ISM transceiver for ultra low power networks…
“The nRF24L01 module is a component that allows for wireless communication between two separate Arduino boards. It utilizes the NRF24 radio transceiver and, on a PCB, attaches to an antenna to create a functioning radio transceiver. It uses a 2.4 GHz band and baud rates of 250 kilobits per second, 1 megabit per second, and 2 megabits per second. It typically performs best at a range of up to 50m, but with low interference, it can possibly go much further. I’ve been able to have it work outside of my dorm while having the receiver inside.”

His writeup, which is on the DigiKey website. covers an introduction to the Nordic module, the pin outs for working with Arduino, the PCB he created for the project, and setting up the channel numbers for his network.
“There’s more ground to cover when it comes to coding for specific applications, but this should provide enough information to get you all set up and started on your wireless projects. While there are a number of transceivers out there, I personally find the NRF24L01 a perfect place to start given its ease of installation and the smooth compatibility with the Arduino.”
Thanks to DigiKey for highlighting this one. Note that it comes from the Maker.io section of the distributor’s website, where they feature a number of projects (for example a PiPyPirate Radio, based on a Raspberry Pi, is already catching my eye).
