This weekend we dove headfirst into getting fluxengine and our 5.25" disk drive working with the floppy featherwing. good news is that we were able to add support to Adafruit_Floppy and with a little refactoring, add 360K disk MFM decoding. we thought we didn't have any DOS floppies but we did find one in a pile (mouse driver). we then used fluxengine to read the data off to verify before implementing mass storage support. once we got that working we spent a few hours on C64 disk reading, these disks are kinda odd and not formatted like 'normal' diskettes - there is a different encoding scheme and variable sectors per track! we also designed a feather esp32 v2 and a smol handheld game BFF for QT Py.
The Great Search - small 'cap-less' headphone driver
https://www.digikey.com/short/0b3v2192
For our tiny handheld gamer board, we want to have a headphone driver that does not require a lot of board space. even if the chip is small, most simple amps require output blocking caps to avoid DC bias on the speakers. but, now-a-days you can get 'cap-less' drivers, that generate a faux-ground. this makes for a very tiny board. let's find a chip that is small, but not BGA/CSP, that will fit nicely into our design
