I just updated the Hackaday Project page, so I guess it's time to spread the good word on my blog as well. I received some good design help from a friend, and was finally able to order a new batch of completely redesigned C64FC boards!
This is the preview I got from OSHPark today, as I placed the order.
The horrible, bulky, slow Bluetooth module has been ditched and replaced with a USB type B device connector. This means you will now need a cable, but the file transfers will be 10 times faster than before. Literally: 2 seconds instead of 20. The USB support is implemented with V-USB on the ATmega16, and will use HID standards to stay driver-free.
I had to purchase a few new SMD components (mainly zeners and transistors), and they will hopefully arrive in time with the PCBs.
