History tells us probably not. Did the US pay anything for the extermination of native americans? Or for the generations of people who lived in slavery? Did Turkey pay for the Armenian genocide? Did Russia pay for the millions of people killed in gulags and the Holodomor?

While I agree this is a shit thing to do, I am looking forward to the influx of cheap hardware.

The tape head is basically a small and really sensitive electromagnet. Magnetized tape creates small disturbances in the magnetic signal. Amplify those disturbances and you get sound. Similar to an antenna, but only works in close proximity.

This also works in reverse. Feed an audio signal through the electromagnet, and the electromagnet will create the disturbances in whatever is next to it. You can do this to record to a tape, or you can do this to pass sound to another tape head, which is how these aux cassettes work.

You can build one yourself really easily. Just take the tape head from a broken player and solder to an aux cable. Take a cassette, remove the tape, and put the tape head in the middle portion so it comes into contact with the player tape head.
