Selling pair of cables. Each cable is one foot long. Ends with bare wires on one side, and a 3.5mm audio connector on the other (female for one cable, male for the other).
Useful for experiments: you can measure the signals using an oscilloscope by connecting voltage probes to the bare wires. (Of course you can strip an audio cable yourself, but why go through the extra work when these are ready-made?)
In great condition; used only a couple of times.
Price negotiable. Cash only. Pickup on Cornell University campus.
