Not long ago I received the Pi Switch kit from Pi Supply.
I have created a couple of videos to show what the Pi Switch is for, how to build it and how it works.
The first video is on how to build.
shortly I will add the one on how to configure the software part and how to use it.
The software that is currently available is only working for Rasbian Wheezy but a new one for Jessie will be available soon. For the moment I have created a little patch on my GitHub also thanks to Russel Davis (aka @ukscone) and we have asked Pi Supply to test it and upload it to their channel.
Hope this is coming handy for some of you!
