I have an original Kickstarter Dual BigBox. There are a few posts on changing the code flashed to the EEPROM to alter the beep, i.e. freq and duration. As I'm going to replace the Rumba sometime soon and I don't want to re-flash the code just for that, it occurred to be that the beeper itself is almost certainly on the front panel and not on the board? If so it may be possible to either remove the electrical connection (cut a wire or track) or place a resistor in series or in some other way mute the sound?
