JakeSoft:
You may be able to plop down a 16MB flash chip in place of your SD card on a future revision of DIYino. You'll get that USB-sound transfer feature you were looking for a while back in a conversation I remember. I could see two USB ports: One for the MCU, one for the sound. Might take up less room than the SD card too.
You remember right, once I reach break-even with my DIYino design, I want to embark on a quest for a high-end Arduino saber core. I already sketched up in my mind the core requirements:
- Flash instead of SD
- Equally important in my eyes is that it must have only a single USB port. An USB takes up nearly the same room as an SD, and latter is flatter.
- I think about an Atmega with more memory.
- Use flash to store arbitrary data accessible by the uC.
However this one I intend to do in a team.
