Literary Clock Scripts

See source repository -- https://github.com/knobunc/kindle-clock

What is this?

This is a repo to make installation and maintenance of the "literary clock" for the Kindle a little easier. All credit to tjaap, you can see his instructable at: https://www.instructables.com/id/Literary-Clock-Made-From-E-reader/

How to Install

1. Jailbreak your Kindle, install launchpad, python, and usbnet. Instructions are at step 2 of https://www.instructables.com/id/Literary-Clock-Made-From-E-reader/
   1. I would make a directory of all of the uninstall scripts on the device too, so removal is easier
2. git clone the repo to somewhere you can rsync from
3. Install your private key in /mnt/us/usbnet/etc/dot.ssh so rsync will work for updates
4. ssh into the kindle
   1. If you want to use usbnet rather than wifi (on Linux):
   2. Copy the launchpad/startClock.ini to the launchpad directory on the USB filesystem on the Kindle and hit shift shift spacebar to reread the launchpad config (or just Restart, the timing can be tricky)
   3. Start USBNet with shift n
   4. Enable the network interface

sudo ifconfig usb0 192.168.2.1/24

5. And ssh in (-a disables agent forwarding so we can test our key). There is no password, hit enter.

ssh -a [email protected]

5. On the kindle rsync the utils directory:

/usr/bin/rsync -rltD --omit-dir-times --delete-delay --delay-updates [email protected]:kindle/kindle-clock/utils/ /mnt/us/utils

6. Install the needed cron jobs:

mntroot rw
cat >> /etc/crontab/root <<EOF
* * * * * sh /mnt/us/timelit/timelit.sh
5 0 * * * sh /mnt/us/utils/update.sh > /mnt/us/updatelog 2>&1
EOF
mntroot ro

7. Add a boot script to cleanup the clockisticking file... since it shouldn't be after a boot

mntroot rw
cp /mnt/us/utils/clean-clock /etc/init.d/
cd /etc/rcS.d
ln -s ../init.d/clean-clock S77clean-clock
mntroot ro

8. Sync everything over with an update:

cd /mnt/us
sh /mnt/us/utils/update.sh

9. Tell launchpad to reload its config:

/etc/init.d/launchpad restart

10. Type shift c to start the clock (and to end it). You may need to wait a moment between the shift and the c for it to register correctly.

Usage

Commands added to launchpad:

• shift c: Starts or stops the clock
• shift n: Starts or stops usbnet
• shift u: Kicks off a manual update
