KryoFlux is an advanced software-programmable FDC (Floppy Disk Controller) system that runs on small and cheap ARM7-based devices and connects to a host PC over the ubiquitous USB connector. It reads (and in the future, will write) flux transitions from magnetic media (most commonly, floppy disks) at a very fine resolution. KryoFlux can read data with no regard for what disk format or copy protection a disk may contain, and it can also read disks originally written with different (and even varying) bit cell widths and drive speeds, with a normal fixed-speed drive.
KryoFlux is available for free for private non-commercial use. You will however need to build or buy a board based on our open hardware design.
KryoFlux supports dumping any floppy disk to “stream files”, which contain the raw flux transition information. It supports output of a range of common “sector dumps” (e.g. ADF) to allow you to use your dumped images right away in your favourite emulator.
