-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.
