Ratpack - the Remote Control
 Sven Kräuter

Frank, Sammy & Dean were a great team known as the "Rat Pack". What's true for these fellows is also true for Sinatra, Ruby and Arduino.

The remote control was the result of an awesome workshop session where we played around a little with different ideas.

It is basically on online on/off switch that's connected to a server. On the over end there's an online controlled LED that lights up if the server says to.

Quite nice if you think about what one can do now based on this little toy!
