We were doing some remodeling at the old hackerspace and cut a wire from an old intercom system that was doing nothing but hang in the way. A while later we noticed a puddle under it, thought not much of it. Later there was a bigger puddle and then the jokes got more incredulous. WTF the building is bleeding? It’s very thin oil, possibly used for lubing the cable up when it was pulled through the insulation jacket, but that’s a lot of oil for that. This is unshielded, untwisted audio cable, maybe it’s some sort of shielding or impedence matching?. We’re a bit stumped out here at i3Detroit, anyone got a clue?
UPDATE: the wire doe ave some electrical inulation and the conductor are not made of paper. The colors are red, black, and yellow; the pinout could be anything, but I think it’s probably power, ground, and signal.
