When you design the final board, consider making two boards - one for all your logic, and a separate one for all your user-facing I/O - blinkenlights, toggles, buttons, and so on, with something like a ribbon cable connection for them. Being able to separately mount your I/O from your logic board gives you more freedom when it comes time to put the whole thing into some kind of case. Nice read, thanks for sharing.
