[Ray] has created RFToy, a simple gadget to aid in setting up wireless systems with a variety of common radio modules. RFToy is an open source microcontroller board running on an ATmega328. While RFToy is Arduino code compatible, [Ray] chose to ditch the familiar Arduino shield layout for one that makes it easier to install RF modules, and is more handheld friendly.
[RFToy] includes headers for the popular nRF24L01 2.4 GHz transceiver, as well as 433/315 transmitters and receivers found in many low-cost wireless electronic devices. The 128×64 pixel OLED screen and 3 button interface make it easy to set up simple user interfaces for testing new designs.
[Ray] hasn’t broken any new ground here. What he has done is create a simple tool for wireless projects. Anyone who’s worked on a wireless system can tell you that tools like this are invaluable for debugging why your circuit isn’t talking. Is it the transmitter? The receiver? Something else in the power supply circuit?
Check out [Ray’s] demo video after the break. In it, he sniffs, records, and plays back signals from several remote-controlled outlets. [Ray] also has a great demo of sending temperature data back and forth using an nRF24L01.

I read that as RFtoyuino, what is wrong with my head.
That is fucking neat. I love it
This was published just in time, I have been designing something like this for a while now to create a large sensor network to monitor temperatures and control heating around the house. Just need get buch of there and add NRF24 to the RPi and start logging data.
The all powerfull no-name Chinese manufacturers also make a module where they added a PA to the NRF24 chip, can go up to +20dBm of transmit power ;-)
I thought the same thing, just got a 5 pack of etekcity plugs for $20 , wanted to interface into home automation
Interesting this project still uses VirtualWire, and not “Radiohead”, which supersedes it!
I think this has use for many projects. I’ll put it on my wish list.
