CAT5 Ethernet cables to connect audio from my PC to my room stereo. My shop has a nice stereo on the far wall away from my PCs and work bench. Rather then purchase a long audio extension cable I scrounged up some CAT5 Ethernet cable and audio connectors, a few quick splices and a 30 foot audio cable is born. Sounds great!
A few hundred feet of CAT5 cable left over from a home networking project. Saved so the wire could be recycled.
RCA audio cables and a small stereo headphone jack also scrounged from a previous audio project where they were scrounged from some left over audio cables.
To splice the audio cables to the CAT5 start by picking two pairs of wires, I used the Brown and Orange pairs for Left and Right audio.
The wires are soldered and each connection is staggered to prevent shorts.
After building the cable check it with an Ohm Meter to make sure its correct. Then install.
