What does HackerNews think of greaseweazle?
Tools for accessing a floppy drive at the raw flux level
These days, there's GreaseWeazle[0], setting the standard.

I haven't tested this, it's on my to do list.
I recently got the parts but haven't tried it yet. I have vinatge machines that otherwise need a real floppy controller and not a modern one (nothing found on any motherboards newer than 486's), or a catweasel (also no longer made) or a KryoFlux (the nuclear option and not open source).
Greaseweasel (https://github.com/keirf/Greaseweazle) has come along recently as an open source catweasel. (the pcb design files are there too, just buried away in a zip file in one of the wiki pages, not directly in git, so both hardware and software source is aclvailable. Follow Hardware Assembly -> F7 Lightning Plus, scroll to bottom)
But that's more complicated.
I love how the FluxEngine is really just a single off-the-shelf part. You don't even need so much as a wiring/pinout adapter pcb for the 34-pin connector. You can just solder it directly to the dev board.
