[arm-allstar] UPS Suggestions...

[Jesse Royall]

 I looked at this option as well but wanted to keep things running during the day. Sometimes I was in and out and figured I could keep the Read/Writes down if it just stayed on all day and kept things registered since I was having registration issues. Sometime I could register first thing in the morning.. then it'll stop working for a few days then it'll register and work for a few hours and then stop. Rebooting at times seemed to make it stop working for a few days.

 I want to make everyone aware that in the howto's at hamvoip.org there is a
power shutdown circuit that will shutdown
 the Pi and any associated radio properly upon power failure and return
power when it comes back up. We had boards made to do this which are
available unpopulated or wired.

​While this is different than a UPS backup as it does not sustain operation
in a power failure it might work in some applications. It was intended for
unattended power shutdown in a portable or mobile application.
