"Turn your phone into a nuclear reactor (by plugging it into a wall outlet served by a nuclear power plant)"
Very funny.
However, your analogy is not equivalent to, nor an example for, what I said. There's a difference between a phone's own USB/audiojack interfaces and a wall outlet.
Why do some people get so hung up about minor things in life. The OP has done a fantastic job, not just building it, but both the delivery and mechanics.
