At this stage I managed to wire up some leds and the pir sensor only in order to start to play with it, so after wired all up I plugged it into the wall socket and placed the sensor near the floor level, I noticed that the working angle is quite wide (120 degrees if I undersand well), so I will menage to place something circular, like a little slice of a plastic tube around it to make it triggered only if something is perfectly in front of it.

Meanwhile here it is a little trailer of the version 0.1a (thanks to Giulia for the Oscar awards nomination :) ).
