Bit banging a 3.5" Floppy Drive

  A floppy driver written in rust

Interesting and fun project! I found the MFM encoding page particularly enlightening as it explained why you have to write a full sector at a time on a floppy, even though there's nothing physically constraining you to that so far as I could see on the electromechanical/hardware side of things.

And on that page the "make sure the compiler didn't inject 10,000 lines of boundary checks" bit told me everything I needed to know about what language the project was written in :lol: - here's the link to the driver: https://github.com/SharpCoder/floppy-driver-rs

I'm glad to see the Teensy continuing to get love; I adopted it back when it was at v1 and v2 as it was just such a complete no-brainer of a better choice than the Arduino stack everyone was using back then. I think now there's even an Arduino-on-Teensy software stack, but I've moved to just using STM32 directly and have greatly enjoyed coding for that target in rust.

  Tools for accessing a floppy drive at the raw flux level

Take a look at the Greaseweazle https://github.com/keirf/greaseweazle to see what a really high-end solution in this space looks like. It's intended as a from-scratch alternative to the beter known KryoFlux.
