Kindle Weather
STOP, THIS WILL BRICK YOUR KINDLE, ONLY FOR LINUX GEEK.
UNLESS YOU KNOW ALL THE FOLLOWING LINUX COMMANDS, GO AWAY, THIS IS NOT FOR YOU.
Big Thanks to Matthew Petroff for his sharing.
This project is fully based on the project shared by Matthew Petroff: http://mpetroff.net/2012/09/kindle-weather-display/
Without his kind share of this great work, my kindle 3 might still sleep in the dust.
The changes I made:
-
Use
crontab
instead ofkite
or stoppowerd
by changing thesuspend_levels
. -
Reorganized the
weather_script.py
by spliting weather API out. -
Change
weather-script-preprocess.svg
to fit the weather API. -
Warn user when low battery(less than 10%)
-
I tried to change
weather-script-preprocess.svg
to use<image>
tag for external image which allow me to easily change the icon, but I failed to at the rsvg-convert point. So still in embedded way.
License
- The code is in MIT license.
- The
weather_script.py
file is based on the work of Matthew Petroff 2012, MIT license. - The
weather-script-preprocess.svg
and its embedded icon are under CC0 Public Domain Dedication license by Matthew Petroff also. I(Gris Ge) did small change to fit the weather.com API.
Pre-requirements
- Kindle 3 wireless (Only tested on this one).
- The API key from weather.com
- Kindle Jailbreak and USB network.
- A kindle WIFI accessible Linux server with
python2 pngcrush librsvg2-tools
.
HowTo
Kindle Side
Jailbreak your Kindle and install USB network.
- The above wiki pages works on me. The tips would be disable wifi at the initial login, then change root password, change ssh config to allow wifi login, set as auto start, reboot.
Install weather display script
- Edit the
URL
indisplay-weather.sh
by pointing to your own http server. - Create folder
mkdir /mnt/base-us/weather
. - Make sure kindle root mount point is writeable
mntroot rw
scp display-weather.sh root@k3w:/usr/bin/
- Make sure
display-weather.sh
is executable viachmod +x
on kindle.
Setup crontab
-
Execute
mntroot rw
. -
Add this line into
/etc/crontab/root
5 6-22 * * * /usr/bin/display-weather.sh
-
Changed above line to suit your needs.
Keep your kindle connected to a USB power during use.
- I(Gris Ge) don't suggest your to hack kindle in order to stop the auto suspend, you might face batter drain. Please collect your kindle to a USB charger always.
reboot
command.
Reboot your kindle via Server Side
Install httpd daemon.
sudo yum install httpd pngcrush librsvg2-tools python2 -y
sudo systemctl enable httpd
sudo systemctl start httpd
Create weather output folder with correct permission.
sudo mkdir /var/www/html/weather
sudo chmod 777 /var/www/html/weather/
or usechown
.
Setup crontab
-
Create a script named as kindle_weather.sh like below:
export KW_INCLUDE_SCI=1
^ Include China Shanghai Composite index.
export KW_LATITUDE=30.6586 export KW_LONGTITUDE=104.0647
KW_AIRPORT=CTU
^ If you have airport in your city, use something like instead
export KW_WEATHER_KEY="<I_WILL_NOT_TELL_YOU>"
^ Weather.com API key
export KW_AQI_CITY="chengdu"
^ aqicn.org city name.
export KW_LANSCAPE_LEFT=1
^ Lanscape left mode(usb port at your right side).
KW_LANSCAPE_RIGHT for usb port at your left side.
export KW_OUTPUT="/var/www/html/weather/weather.png"
/home/fge/Source/kindle-weather/weather_script.py ```
-
Add this line to
crontab -e
to refresh weather every 30 minutes during 6AM to 10PM:
0,30 6-22 * * * /home/fge/bin/kindle_weather.sh 1>/dev/null 2>/dev/null ```
Create initial weather PNG

http://<your_server_hostname>/weather/weather.png
