Software:Solar Power
These scripts save significant power by shutting down HDMI, Ethernet, USB ports and connected USB devices.
To use them call buspower_up at the beginning of hive.sh and call buspower_down at the end of hive.sh.
WARNING! These scripts are in alpha testing and not for production release.
Oops, after running 24 hours, there were lots of hung processes:

A work around?

sync_clock.sh
Syncs the clock. Called by cron and rc.local.
/home/hivetool/buspower_up
timeout 20 /usr/sbin/ntpd -qg
/home/hivetool/buspower_down
rc.local
- Turn off HDMI (saves about 20 ma.)
- Set the clock on boot up. (Note ntpd must be disabled.)
/opt/vc/bin/tvservice -off
timeout 60 /home/hivetool/sync_clock.sh
crontab
Syncs the clock four times a day. (1:07, 7:07, 13:07, and 19:07)
