Hi Jean-Marc,<div><br></div><div>As far as I can see, it is not easy to build a RF circuit from the scratch. It usually requires a lot of trial-and-error. So I prefer off-the-shelf modules. Currently I'm testing two different modules:</div>
<div><br></div><div>One is based on the very popular Nordic nRF24+ chip (around $5)</div><div><br></div><div><a href="http://www.hoperf.com/rf_fsk/24g/RFM70.htm">http://www.hoperf.com/rf_fsk/24g/RFM70.htm</a></div><div><br>
</div><div>I grabbed mine here</div><div><br></div><div><a href="http://www.futurlec.com/">http://www.futurlec.com/</a></div><div><br></div><div>The other one is Microchip MRF24J40 module (around $9)</div><div><br></div><div>

Hi Mahdi,<div><br></div><div>I happen to building a open-source wireless network for use with low end microcontroller systems such as Arduino. For now, the protocol takes up around 30K of program memory and 2K of data, which hopefully will be downsized to fit into Arduino Uno. If successful, it will be using off-the-shelf IEEE802.15.4 wireless module ($5 - $10) rather than wifi. So you can build each control/sensor board for around $10. I'll post the schematic and the source on my blog sometime later in this year.</div>

Hi, <div><br></div><div>I was wondering if anyone at the ModLab has played around with home automation. I have been playing around with this sort of thing for a long time, its really interesting now that things like the raspberry pi board are available at such a small size. </div>
<div><br></div><div>I was wondering if anyone knows of wifi switches and sensors that could be deployed around the house to control things like lights and lamps on the cheap that doesn't require a lot of installation and relativity cheap. I am hoping to build something small like a prototype and see where it goes from there. </div>
<div><br></div><div>I would like to use the raspberry pi as the controller and have sensors connect to it over the wifi and potentially have something like an iPhone do the connecting. I have built servers like this before, I just looking for some information on hardware and what is possible.</div>
