This project is very old. It's been "finished" for several years.
The developer is a very good engineer and the product reportadly works well, however the PCB design is rather clunky.
If only the PCB had been designed to be the same form factor as an FDD it could have gone inside the computer instead of the FDD!
If the USB connector had been a mini-USB connector the cable could have been inserted through the hole in the computer case left for the floppy disk.
