[arm-allstar] Shari Node Fan Control?

[David McGough]

Chris,

Controlling the fan should be very easy to accomplish using the "gpio" 
command included with HamVoIP.

You can retrieve the current CPU/SoC temperature using this command:

/opt/vc/bin/vcgencmd measure_temp


A little script to monitor the temperature and turn the fan 
on/off, as needed, wouldn't be more than a few lines of code.
