[sdiy] NIC-based wave folder/shaper

Agreed... the bounding circuit would be better... but I thought
it might also be more complex because most of these use the negative
feedback path... and in the NIC there are two feedback paths.

Brute force bounding of the output could work... I'd still try
the power supply pins first beacuse of the simplicity of it.

The higher frequencies might not matter anyway... old arguement of the
harmonics being above human hearing anyway...
