Take a look at the Applesauce.
It hooks up to a lot of different floppy drives and records and decodes the flux.
Version2 of the hardware is being sourced and should be available in a few months.
Good grief, there are more of these things floating around than one can
shake a stick at. The Greasweazel is perhaps the cheapest, using a $3
($1.30 or so from Aliexpress) STM32F103 "Blue Pill" board.
It's almost trivial doing this if you don't need the "eye candy".
Basically you run a timer in capture mode, with capture triggered by an
edge on the drive's "read data" line.
Modern MCUs don't even break a sweat doing this.
It's nice seeing the proliferation after many years of harping on the
subject...
