Simple stats script:

#!/bin/bash
clear
while [ 1 ]
do
 uptime
 df -h | grep Filesystem
 df -h | grep rootfs
 df -h | grep usb
 echo ""
 Temp1=$(cat /sys/bus/i2c/drivers/lm90/0-004c/temp1_input)
 Temp2=$(cat /sys/bus/i2c/drivers/lm90/0-004c/temp2_input)
 echo "MB T  = "$Temp1
 echo "CPU T = "$Temp2
 sleep 1
 clear
done

Insert it in a file. I called it stats.sh

chmod a+x stats.sh

and run with ./stats.sh

It updates every second and returns:

• uptime with load
• Disk space and usb disk space
• MB temp
• CPU temp

You can add all you want in there or remove what you don’t need :-)

Just purchased a PC Engines Alix 3d3. online from MS Distribution (UK) for ~£110.00. I have a plan for it… read on…

Specs follow:

First Mod: Heatsink with fan!

I noticed that my processor was going up to the 50′s plus degrees when working, so I decided to keep it cool by adding a Heatsing with a FAN. I found one on Amazon.co.uk, specifically designed for Graphics chips, so I thought it would be ok for my Alix. It came with a self-adhesive strip on the bottom which made installation simple. Then after seeing that an 18V supply for the Alix was too high, and hmm… I ran out of adequate resistors to step down the voltage… I hooked on the 5V supply right behind the Serial port! And that ensures i get minimal fan spin, and hence virtually no noise from the fan. The airflow is enough to cool down the heatsink, as there is a noticeable difference when the fan is operational and not.

Update: While compiling the kernel the cpu temperature stays below 42 degrees (Celsius)

Application:

I am now trying to develop a home-made GPS tracker with a GPRS modem to “report back” the location… More on this coming soon!
