Streaming audio around your house, such as podcasts, Internet radio or just some music is a great way to relax and can come in useful when throwing a party. But itâ€™s expensive. Use your pre-existing telephone wiring to run a house-wide audio system on the cheap!

The “master” jack which is pictured beside his laptop above, has an extra port which is for input. This takes the audio from the laptop and feeds it into the network. All the rest, which are stationed around the house accommodate 3.5mm headphone jacks. This means you can plug in big stereos or iPod earphones, whichever you prefer.
Probably the coolest thing about this hack is that the power to run the stereos is also supplied through the network via the Cat-3 telephone cable. This saves having two wires for each stereo running from each socket. You can see how simple the wiring is in the picture above â€“ that is the insides of a wall junction box with basic circuitry and soldering required.
