Doesn't SuperCard Pro already do this?  The hardware isn't open source, 
but the USB control protocol to read and write flux transitions on an 
entire track is open and well documented.  And there are already several 
tools to exercise the protocol.  Sure, one could replicate the hardware 
work for kicks, but that isn't the real heavy lift.  Advanced tools for 
manipulating the flux images for low level encoding, high level format, 
and file system is the prize.  The Amiga ADF disk tools project is a 
really good start... (supports dozens of formats beyond Amiga).
