It might not be necessary to calibrate, if the raw value is sent to

It is still be necessary to ensure the values are within the range of

Yes, nice aren't they? I would not use Arduino where power was
critical. I had assumed that since a server was involved, one more
device wouldn't stretch the power budget that far, especially given
the benefit that voltage monitoring brings.
Oh yes, we will have a fitPC2 and a dreamplug
Keep it simple is probably the best…
I've got an Arduino Diecimila, which is quite big for our purpose, I
also have a PIC32 Pinguino board, which is really great but too much
powerful…
Xavier, we could make a really tiny board, or buy one, with a small
microcontroller (Microchip is best for USB

Dear XS developers,
As we plan to install and deploy a fitPC2 as a School Server in our
NosyKomba deployment in Madgascar for OLPC France, we plan to powered
it with the 12 VDC power-rail (powered by solar panel + battery +
regulator).
=As we did it with another XS installed but powered by 220VAC
I understand the requirement. There are two approaches.
One measures voltage, and when it goes below a threshold begins
shutdown, and when it goes below a final threshold it disconnects the
load.
The second approach is a charge controller, which estimates the
capacity of the battery bank by
