[KDE] battery monitor

There's another thread that shows how to use python
to control the LEDs; this can be easily integrated into
a battery monitor script so that when your battery gets
below a certain level the LEDs start blinking red.

For example, here's my battery monitor script:

Code:

#!/bin/sh

X=`battery-status | awk '{print $4}'`

if [ ${#X} -lt 5 ]

then

  play-sound /usr/local/kde/share/sounds/KDE_Notify.wav &

  kdialog --title "Battery Status" --msgbox ". . . . . . . . .  $X  . . . . . . . . ." &

  python /home/user/blinkenlight &

fi

This runs every 10 minutes via cron (yes, if you look you
can find a cron that runs on the n810).

the python script looks like this (thanks to eber42):

Code:

#! /usr/bin/python



import time

import dbus

bus = dbus.SystemBus()

obj = bus.get_object('com.nokia.mce','/com/nokia/mce/request')

iface = dbus.Interface(obj,dbus_interface='com.nokia.mce.request')

led_pattern = 'PatternError'



# led on

iface.req_led_pattern_activate(led_pattern)



# wait 5s

time.sleep(5)



# led off

iface.req_led_pattern_deactivate(led_pattern)

Well, it's fun if nothing else ...

Re: battery monitor

You can control the LED from a shell script: no need for Python for something this simple. See Changing the led colour indicators?

Re: battery monitor

thanks for that - much "cleaner"

Is there any central collection of "how to control your
tablet" tutorials and such that deals with things like
controlling LEDs etc?

Re: battery monitor

no, there's not a central place for these types of info. you have search/google/hunt for them all over the interweb. i know it sux, but iiwii and it's something we all learn to tolerate.

Re: battery monitor

sadly...

there is a wiki on this page, dropping it there would be a nice start. or at the very least a link.

hmm, a gui front end for cron is maybe something this
tablet could make use off...
