+# Bash Scripts #
+
+I teared the notifier apart and placed the notifier's board inside my home server.
+Due to its size, the RGB LED creates some interesting optical effects if you place it 2-4cm
+behind the venting holes.
+
+Here are some simple scripts that use various data to set the LED's color.
+
+
+
+## mled-discomode ##
+
+This script simply cycles through all available colors. I called it disco mode due to the optical
+phenomena that take place as the light crosses the air vents.
+
+
+
+## mled-cputemp ##
+
+This script works really well for my machine. It uses the `sensors` program to get the CPU
+temperature.
+
+If the CPU is at or under the low threshold, the LED turns blue. If it is at or above the
+high threshold, the LED turns red. If it is in the middle, it gets green.
+
+It is actually very informative for the machine's state. You can easily detect CPU load.
+
+
+
+## mled-iowait, mled-iowaitdetailed ##
+
+My home server doesn't have any LEDs for HDD activity, though it has plenty of HDDs.
+These two scripts attempt to make up for this shortcoming when I need some quick profiling of the machine.
+They actually work better than common HDD activity LEDs because they are based on iowait percentage in one
+second periods (adjustable).
+
+`mled-iowait` has 3 levels, so you get only to set a low and a high threshold.
+
+`mled-iowaitdetailed` has 6 levels of activity, so you can set 5 thresholds. Also below the lowest threshold,
+it sets the notifier to off, which turns to be a good approach.
