[Voyage-linux] Re: Any Hardware Voltage Monitoring/Usage Sensors Available for ALIX boards?

[linux123]

I wanted to thank everyone who responded with this information. It’s a shame
that there are no software based sensors but I guess at the end of the day
it would only add additional overhead.

It’s interesting to hear that there would be a 5v regulator of some sort
just after the DC Input jack. If that's the case then I can see no reason
why the manual for the board tells you to use between 7-20v MAX. I chose the
15.5v value only because it matched the Wall Wart that came with the board
and planned on working backwards from there in terms of Input power once I
felt I had sufficient information to pull the trigger....err, I mean, twist
the knob lower

One thing I will mention is that I did have the board dialed down to the
12.5v range for a few hours one evening during a jam session and swore the
soundstage seemed a bit more distant than usual but it may have been the
beer talking to me. I will need to do further testing before I am willing to
say much more about that occurrence.

To "Jeff Mai", 

I would love to be able to feed the board between 9-10v but before I try it
out I am going to place a call into Ayre to find out how much juice the DAC
is looking for to run its circuitry. If the DAC is looking for 5v, then I
may need to stay around the 13.5-14v range for Input power in order to keep
everything happy.

Thanks again
