What, if any, indicators of system status or activity are available on the Pi?
Audio - I'm talking about a beep when it's turned off, or a series of beeps indicating POST information, etc.
Video - Does it have a power on LED? What about a disk activity LED, like you get on the front panel of a lot of PCs etc.
If none, are there any peripheral options available to connect via USB in order to present such information?
I am considering a headless project for use in-car, (continuous loop recording of audio, parking sensors etc). And I would like to know that it's working without having to login etc.
