My old cooling system improved recently ! | 2016-11-24 | my-old-cooling-system-improved-recently | post | Hacking |
It's been almost three years since [I've written an article]({% post_url 2014-01-29-refresh-system-active-passive %}) on a cooling system I've came up with, for the raspberry PI.
Beforehand, the fan was enabled once the PI was plugged in, and never stopped...
Now, there is a script which decides when enabling the fan (based on a time slot and a temperature limit) with the help of a MOFSET N transistor commanded by GPIO Pins (Yeah, again !).
However, the script is still run each minute :
# crontab -e
... add in there :
* * * * * bash /root/PICool.sh > /dev/null 2>&1
And you may also want the wiring scheme of the system :
PS : The DC motor represents the fan which is close to the processor unit on the chip.
