A dog owner has used his Raspberry Pi to build a noise-sensing circuit that opens the door for the canine when it barks.
Dave Hunt’s project was posted on the Raspberry Pi website (http://www.raspberrypi.org/archives/4274), with Hunt saying that the barking of his new dog to be let in and out drove him to design the Pi-Rex.
For those who wish to create their own Pi-Rex doggy-door, Hunt has posted expansive instructions and details on his website (http://www.davidhunt.ie/?p=3132). The meat of the circuit is a noise detector adjusted to respond to barking noises which fires a door-unlocking motor when the sounds are detected.
Hunt, who lives in Limerick, says he picked up the necessary audio detection circuit in high-street store Maplin for €9.99, and that construction took a swift half-an-hour.
While the door currently only opens, Hunt specifies that the invention is only a proof of concept, not a security fashion.
