In an optimistic mood I bought this one, it's a wireless transmitter 433.92Mhz
At home I have a set like this that uses 433Mhz to remotely switch devices on and off.
Before the Pi I was programming on the Fez Panda and for that device I have found some code how to control the wireless transmitter. I couldn't find it for the Pi.
Now my question is: is it even possible to control this transmitter via the Pi?
